The invention relates to a dental handpiece driller clamping device, which comprises a pressing element and a shaft sleeve, wherein the pressing element is positioned at the top inside the shaft sleeve in a way capable of vertically sliding; the upper end of the pressing element extends out of the top of the shaft sleeve; a driller clamping element is arranged in a position, corresponding to the lower side position of the pressing element, in the shaft sleeve; two notches which are in vertical arrangement and can be opened when being pressed are oppositely formed in the side wall of the top of the driller clamping element; the top of the driller clamping element can be extruded by downwards pressing the pressing element, so that the notches can be opened to tightly clamp a driller arranged in the driller clamping element; and an elastic element used for upwards rebounding the downwards pressed pressing element is arranged in a position, corresponding to the position between the pressing element and the driller clamping element, in the shaft sleeve. The dental handpiece driller clamping device has the beneficial effects that the clamping device inherits the advantages of a KV shaft core; meanwhile, the elastic element for upwards rebounding the pressing element is added; the driller can be released by the driller clamping element by downwards pressing the pressing element again; the driller change speed is accelerated; the corresponding pressing force is smaller than that in the prior art; and the user experience enhancement is facilitated.

The invention relates to a special escalator running sliding seat which runs up and down around the handrail in the stairwell, and is mainly used in buildings without elevator passages. The lower track, the upper track and the arc-shaped curved track of the guide pulley constitute the handrail-shaped automatic rotating track and can rotate up and down the stairs. The sliding guide bearings on the upper and lower ends of one side of the sliding seat are located in the upper and lower tracks and the power Under the action of the device, it runs up and down along the automatic rotating track. The escalator running controller is located on the sliding seat, which is used to control the working state of the power unit and receive the information sent by the floor controller. The floor controller is located in the stairwell of each floor.

The invention relates to a handle assembly (10) for a door (60), in particular for a motor vehicle door (71), having a pivotable outer handle (11) that can be arranged on the outside of the door (60), a first (12) and second bearing arm (13), which are arranged at opposite ends of the outer handle (11), wherein both bearing arms (12, 13) are configured to engage through recesses (62) in an outer skin (61) of the door (60) into the inside (63) of the door (60), wherein the outer handle (11) can be pivoted from a closed position (43) into an open position (42) during an opening movement (40), and from an open position (42) into the closed position (43) during a closing movement (41), wherein the movement directions (44) of the outer handle (11) further lie in one plane of movement (51) during the opening movement (40) and the closing movement (41) and wherein the recesses (62) are arranged at least essentially in one door plane (50) which is perpendicular to the plane of movement (51) and defines an outer half-space (52) directed toward the outside (65) of the door (60), in which outer half-space (52) the outer handle (11) is located, and an inner half-space (53) directed toward the inside (64) of the door (60). The invention further relates to a door (60), in particular a motor vehicle door (71) having a handle assembly (10), and to a motor vehicle (70) having a motor vehicle door (71).

The invention discloses an ultrasonic welding machine, which comprises a working table, an ultrasonic welding head, a cooling device and a clamping table. There is a first cylinder, the lower part of the front side is slidingly connected with the ultrasonic welding head, the top of the ultrasonic welding head is fixedly connected with the first cylinder, the cooling device is arranged on the periphery of the ultrasonic welding head, and the upper surface of the piston rod of the second cylinder is provided with a chute , the bottom of the clamping table is equipped with sliders, the clamping table slides on the chute and is fixed by bolts, the movable column is connected with the motor through the movable device, and the inner side of the movable column is provided with a pressure sensor, intelligent control The effect of the column automatically approaching the clamping table can adapt to the welding of pipes with different diameters, which is beneficial to prolong the life of the ultrasonic welding head and cooling device. The control switch is more convenient for personal operation. The structure of this device is simple, and it has obvious practicability and efficiency.

The invention relates to an electrical connection member, in particular to a cable connection device. The cable connection device comprises a male plug and a female socket, wherein the male plug comprises a plug body, one end of the plug body is connected with a first clamping head, an annular groove is formed in an outer wall of the first clamping head, the annular groove forms a prop-against surface and a sliding surface, the sliding surface inclines, a convex part is arranged at a high end of the sliding surface, the convex part is arranged on an outer wall of the first clamping head, the convex part is provided with a bevel surface, the bevel surface is smoothly connected with the sliding surface, a jack is arranged in the female socket, a pawl is hinged with a side wall of the jack, afirst spring is connected between the pawl and the side wall of the jack, a first wedge rod is connected with the pawl, a through hole is formed in the side wall of the jack and is used for the firstwedge rod to penetrate through, a second wedge rod is arranged at one side of the through hole in a sliding way, and a second spring is connected between the second wedge rod and the side wall of thejack. By the cable connection device, the problem that a clamping head is easy to naturally slide in the prior art is solved.
