Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of disassembly tools, in particular to an anti-dropping wrench. Background Art
[0002] A wrench is a commonly used installation and disassembly tool. It is a hand tool that uses the principle of leverage to turn bolts, screws, nuts and other threaded fasteners with openings or holes. A wrench usually has an opening or hole for clamping a bolt or nut at one or both ends of the handle. When in use, an external force is applied to the handle along the direction of thread rotation to turn the bolt or nut.
[0003] Existing wrenches are usually divided into two categories: box wrenches and open-end wrenches. When using the two types of wrenches, the joint parts are sleeved on the outside of fasteners such as nuts and bolts, and then the nuts and bolts are loosened or tightened. However, the upper and lower surfaces of the wrench are connected, which often leads to axial slippage during use. Excessive force during use can easily cause safety accidents, which is dangerous, time-consuming, labor-intensive, and inconvenient to operate. Utility Model Content

[0021] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of an anti-drop wrench of the utility model in conjunction with the accompanying drawings.
[0022] like Figures 1 to 6As shown, an anti-slip wrench comprises a wrench body 1, a fixed wrench opening 11 is arranged at one end of the wrench body 1, and a plum blossom wrench opening 12 is arranged at the other end. The design of the two openings enables the anti-slip wrench to adapt to the use requirements of different working conditions. The wrench body 1 is provided with a T-shaped groove 13 at the connection between the fixed wrench opening 11 and the plum blossom wrench opening 12. A limit component 2 that can slide in the T-shaped groove 13 is arranged in the T-shaped groove 13. The limit component 2 can slide to the top of the fixed wrench opening 11 or the plum blossom wrench opening 12, which can effectively prevent the axial slippage of the workpiece to be processed during the working process by affecting the fiber of the nut or screw to be installed or disassembled.
[0023] A connecting plate through hole 131 is provided in the middle of the T-shaped slide groove 13, and the connecting plate through hole 131 is a rectangular structure. The limiting assembly 2 includes a workpiece limiting plate 21 arranged above the T-shaped slide groove 13. The workpiece limiting plate 21 is an arc-shaped structure as a whole. A thrust handle 22 is connected to one end of the workpiece limiting plate 21, and anti-slip grooves are provided on the thrust handle 22. The anti-slip grooves can increase the friction between the thrust handle 22 and the staff, which is more conducive to pushing the thrust handle 22 to a suitable position. A connecting plate 24 is provided below the thrust handle 22, and the connecting plate 24 is perpendicular to the thrust handle 22. The connecting plate 24 passes through the connecting plate through hole 131 and is connected to the slide groove limiting plate 23. The connecting plate 24 is also perpendicular to the slide groove limiting plate 23, wherein the length of the connecting plate through hole 131 is longer than the length of the connecting plate 24, and the connecting plate 24 can move back and forth in the connecting plate through hole 131.
[0024] When in use, the staff selects a suitable wrench opening according to the workpiece to be processed, then inserts the wrench opening into the nut or screw to be processed, pushes the thrust handle 22, pushes the workpiece stop plate 21 to the top of the nut or screw to be processed, and finally performs installation or disassembly. Pushing the workpiece stop plate 21 to the top of the nut or screw to be fixed can effectively prevent the problem of axial slippage of the workpiece to be processed during the work process, can achieve fast, efficient and safe construction, improve work efficiency, reduce the occurrence of safety accidents, and ensure the safety of the staff.
