Intracavity incision anastomat

The invention discloses an intracavity incision anastomat. The intracavity incision anastomat comprises a fixed handle, a closed handle and a jaw opening and closing transmission mechanism which is connected with the closed handle. The closed handle is used for opening and closing a jaw, the closed handle is further connected with a closed handle linkage part, and a locking area is arranged on the closed handle linkage part. The locking area can be locked with an unlocking switch which is fixed on the fixed handle. The fixed handle is provided with a jaw closing safety device, and the unlocking switch can be limited by opening the jaw closing safety device. The locking area can not be locked with the unlocking switch when the jaw is closed, the jaw closing safety device is closed, and the locking area is locked with the unlocking switch when the jaw is closed. In the instrument original state, the jaw closing safety device is placed in the opened mode, closing and opening of the jaw can be operated freely, unlocking operation is needless, and using is convenient.

Clamping jaw device

The invention relates to a clamping jaw device. The clamping jaw device comprises a supporting seat, a guide disk, a hand-hold seat, a locating plate, at least two clamping jaws mounted on the locating plate and the guide disk in a clamping mode, and locking bolt, wherein the guide disk and the hand-hold seat are mounted on the supporting seat and arranged oppositely, the locating plate is mountedon the guide disk and abuts against the hand-hold seat, and the locking bolt penetrates through the locating plate and is connected with the hand-hold seat. At least two arc-shaped grooves rotatablyand symmetrically distributed are formed in the guide disk. At least two clamping jaw openings rotatably and symmetrically distributed are formed in the locating plate, and the clamping jaw openings extend in the radial direction of the locating plate. The clamping jaws comprise clamping jaw parts, guide columns convexly extending from the clamping jaw parts and clamping blocks convexly extendingfrom the clamping jaw parts, the clamping jaw parts penetrate through the clamping jaw openings, the guide columns are located in the arc-shaped grooves, and the clamping blocks correspondingly abut against the guide disk and the locating plate. The clamping jaw device can be adjusted adaptively according to actual requirements, the clamping jaws are closely matched with disassembly and assembly grooves and cannot slip, the operation efficiency is high and the protection performance is high, the clamping jaws with different types and numbers can be correspondingly replaced according to the sizes and numbers of the disassembly and assembly grooves, the universality is high, the using cost is low, and the clamping jaw device is quite practical.

Three jaw adjustable socket ratchet wrench

A three jaw adjustable socket ratchet wrench apparatus comprised of a permanently attached adjustable socket head assembly having three radially positioned jaws which ride trilaterally within an upper cylindrical housing; the extended wrench embodiment has a flexible ratcheting head and a permanently attached three jaw adjustable socket that swivels angularly from +90 folded to +45 to 180 degrees to −45 degrees back to 180 degrees; the extended swiveled arm female lug end is attached onto the male lug of the ratcheting head which has an and an extending cylindrical, shelled, knurled handle which extends outward in two extended distal lengths which can be locked in any of those three positions with the aid of a spring induced détente steel ball bearing; the extended swiveled solid arm has a longitudinal horizontal channel where the outer knurled slide handle rides outward from fully retracted to mid extension adjustment to full extension for extra leverage for high torque requirements; the three vertical jaw members of the adjustable socket head end are abutted inward at 15 degrees to the jaws upper housing radial walls of the same angular taper; each of the jaw member have an interior 120 degrees V-notch which becomes a hexagonal configuration when they are trilaterally spaced apart to accept standard hexagonal configured nuts and bolt type fasteners of various; the adjustable socket's head has a lower driver embodiment having a vertical ⅜ square male shaft that protrudes downward and within the internal central and vertical portion of the ratcheting wheels square female slot; the square male shaft has a vertical through vertical hole to accept a vertical male threaded shaft to control the three jaws to be activated during manual rotation in either a clockwise rotation to expand the jaws opening, and counterclockwise rotation cause the jaws to close in a tapered path; the vertical interior shaft has an upper helix pitch thread screw to accept a horizontal threaded disk of the same thread pitch, the horizontal disk nestles within the horizontal and interior slot on each of the three jaws members, the jaws adjustment in ether rotation is influenced by the users rotation of the lower affixed serrated adjusting knob on the exterior bottom end of the ratcheting head, the ratcheting head having a protective cover plate that is located just below the adjustable sockets lower driver embodiment and nestles into the ratcheting head cavity; the internal vertical adjusting threaded shaft is located between the bottom exterior surface of the ratcheting head and between the radially located jaw members of the sockets' upper housing; when the knurled bottom knob, attached to the main vertical jaw adjusting screw, is rotated by the user, in either direction, this rotation activates the radially positioned jaw members to either move upwards or downwards in a 15 tapered degrees path depending on the axial rotation the use user wish to adjust the three jaw members to; the interior of three jaws are configured hexagonally, 120 degrees v-notch, to grasp a an hexagonal fastener to either tighten or loosen upwards or downward depending on the axial rotation of the main vertical bottom knob; the three jaws maneuvering is accomplished by a smaller, upper diameter actuator ring horizontally seated within a lower internal pocket of each jaw member to influence their movement in either an upward or downward and tapered motion; the main vertical thread screw is attached and retained to the bottom of the adjusting knurled knob; the ratcheting head has a ratcheting pawl that swivels to a reverse to forward ratcheting directions, when the user clicks the ratcheting pawls thumb lever to either a forward or a reverse direction this option will either lock the ratcheting head to tighten a selected bolt fastener or loosen a selected bolt size in the pawls opposing direction; the ratcheting wrenches extending arm has three extended positions for a type of torque requirement needed.

Clamp structure

A clamp structure includes a base plate, a pair of first jaws, and a pair of second jaws. The first jaws extend respectively from two sides of the base plate in a face-to-face manner and form a first jaw opening at their ends. The first jaws are also formed with a pair of cutouts that face each other. The second jaws extend respectively from the pair of cutouts towards the base plate and form a second jaw opening at their ends. Each second jaw has a hook-shaped configuration composed of a first arc near the second jaw opening and a second arc away from the base plate, wherein the first arc has a greater curvature than the second arc. A junction box and a solar panel which are bonded together can be inserted into and thus clamped by the clamp structure so as to be secured against lateral shifting.
