Problems solved by technology

[0003] However, during the use of the adjustable wrench, the user needs to adjust the opening size of the adjustable wrench, but the adjustment is cumbersome. For the disassembly of nuts with different specifications, this will increase the operating time, and the existing adjustable wrench has a single function. , does not have the function of stable clamping

Embodiment 1

[0025] Embodiment one, with reference to Figure 1-4 , a wrench that can be quickly adjusted and has a clamping function, including a first handle 5, a first clamping block 9, a second clamping block 10, and a second handle 12, and the first handle 5 and the second handle 12 pass through each other The interlocking discs are hinged to each other, and the first handle 5 and the head end of the second handle 12 are respectively connected to the second clamping block 10 and the first clamping block 9 by fastening the adjusting bolt 6, so that the user can Adjusting the bolt 6 changes the fastening strength of the first clamping block 9 and the second clamping block 10, which facilitates the control of a certain angle to the first clamping block 9 and the second clamping block 10, and the first clamping block 9 and the second clamping block 10 are mirror images of each other, the end faces of the first clamping block 9 and the second clamping block 10 are provided with a slider fi...

Embodiment 2

[0026] Embodiment two, refer to Figure 3-4 , the slider 7 is superimposed by two cuboids with a square cross section, wherein the width of the small cuboid is the same as the inner width of the chute rod 8, and the inner contour of the slider fixing groove 13 is the same as the outer contour of the small cuboid of the slider 7 , when the slider 7 moves in the chute rod 8, it can still keep the first clamping block 9 and the second clamping block 10 moving in parallel, and the first clamping block 9 and the second clamping block 10 are oppositely clamped Anti-slip strips are evenly provided on the surface to increase the surface roughness, thereby improving the clamping force of the clamped object.

Embodiment 3

[0027] Embodiment three, refer to Figure 2-4 , the first handle 5 and the center position of the end face on the same side of the slider 7 are connected to the rotating seat 4 through rotation, the side wall of the rotating seat 4 is welded with the screw rod 3, the outer wall of the screw rod 3 is slidingly sleeved with the clamping plate 2, and the screw rod The end of 3 is screwed and connected with fastening nut 1, the cross-sectional profile of clamping plate 2 is U-shaped, and the length of screw 3 is greater than the distance from the axis of rotating seat 4 to the tail end of first handle 5, so that the user can pass clamping plate 2 The fixed angle control of the first handle 5 and the second handle 7 is realized, which is convenient for the user to connect the round tube to the first handle 5 or the second handle 12, thereby increasing the torque and reducing the difficulty of operation.

[0028] Working principle: when in use, when the first clamping block 9 and th...

Abstract

The invention discloses a wrench capable of being quickly adjusted and with a clamping function, which comprises a first handle, a first clamping block, a second clamping block and a second handle, the first handle and the second handle are hinged to each other through discs that are coupled to each other. The first ends of the first handle and second handle are respectively and rotatably connected with the second clamping block and the first clamping block through fastening and adjusting bolts. According to the invention, the first handle and the second handle are hinged, the ends of the first handle and second handle are respectively and rotatably connected with the second clamping block and the first clamping block through fastening and adjusting bolts, and then sliding blocks are fixedon the end faces of the first clamping block and second clamping block, on the same side, the two sliding blocks are in sliding connection with a same sliding groove rod, so that a user can achieve quick adjustment of the size of the wrench by pressing the first handle and the second handle inwards during use.

Description

technical field [0001] The invention relates to the technical field of hardware tools, in particular to a wrench that can be quickly adjusted and has a clamping function. Background technique [0002] A wrench is a commonly used installation and removal tool. It is a hand tool that uses the principle of leverage to twist bolts, screws, nuts, and other openings or casings that are threaded to hold bolts or nuts. Wrenches are usually made of structural steel of carbon or alloy materials. The wrench is usually formed with an opening or a sleeve hole for clamping a bolt or a nut at one or both ends of the handle. When in use, an external force is applied to the handle along the thread rotation direction to twist the bolt or nut. Manual wrench is also called ordinary wrench. It is mainly used in ordinary life and work. It is relatively simple to use. It is mainly divided into single-head wrench, double-head wrench, adjustable wrench, ring wrench, multi-purpose wrench, percussion...
