Description

Technical Field

[0001] This utility model belongs to the field of installation and disassembly tools, and specifically relates to an adjustable wrench. Background Technology

[0002] A wrench is a common installation and disassembly tool. It primarily uses the lever principle to tighten or loosen bolts, screws, nuts, and other threaded fasteners. Some wrenches can only be used with bolts and nuts of a fixed size. Other wrenches have adjustable openings, allowing them to tighten or loosen bolts and nuts of various sizes; these are called adjustable wrenches.

[0003] The main advantage of an adjustable wrench is that its opening width can be adjusted within a certain range, thus enabling the tightening and loosening of nuts and bolts of different sizes.

[0004] Current adjustable wrenches primarily rely on two relatively parallel, fixed and movable surfaces to contact nuts and bolts for tightening and loosening. However, with some nuts and bolts having hexagonal or polygonal heads, the small contact area can cause slippage between the wrench and the nut or bolt during tightening. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustable wrench to solve the problem of slippage between the wrench and the nut or bolt caused by the small contact area during the use of current adjustable wrenches.

[0006] To solve the above-mentioned technical problems, this utility model provides an adjustable wrench, including a rotating handle, which is cylindrical, and a wrench fixing component is rotatably connected to one end of the rotating handle. A wrench fixing clamping part is fixedly connected to the wrench fixing component.

[0007] The wrench fixing assembly is also provided with a turbine chamber, in which a wrench turbine is provided, and the wrench turbine is provided with an external thread.

[0008] The wrench fixing assembly is also provided with a wrench movable clamping assembly. The wrench movable clamping assembly is C-shaped and is slidably connected to the wrench fixing assembly. The wrench movable clamping assembly is also provided with several turbine teeth, which are connected to the wrench turbine. When the wrench turbine is rotated, the turbine teeth are slidably connected to the wrench turbine. The wrench turbine is used to drive the wrench movable clamping assembly and the wrench fixing clamping part to move relative to each other.

[0009] The wrench fixing assembly is also provided with a second movable clamping part. The wrench fixing clamping part, the wrench movable clamping assembly and the second movable clamping part together form a wrench clamping cavity, which is used to accommodate nuts or bolts.

[0010] Furthermore, a second movable screw is provided on the side of the second movable clamping part away from the wrench clamping cavity. The second movable screw is provided with external threads. The end of the second movable screw away from the second movable clamping part is provided in the rotating handle. The rotating handle is rotatably connected to the second movable screw.

[0011] Furthermore, the end of the rotary handle connected to the wrench fixing assembly is provided with several limiting grooves, and the end of the wrench fixing assembly connected to the rotary handle is provided with several limiting holes. Limiting pins are provided in the limiting holes, and the limiting pins are slidably connected to the limiting grooves.

[0012] Furthermore, the wrench movable clamping assembly is provided with a screw cavity for the second movable screw to pass through.

[0013] Furthermore, the wrench movable clamping assembly is provided with a first movable clamping part, which is used to clamp the object being clamped. The first movable clamping part is also provided with a limiting cavity, which is used to limit the second movable clamping part.

[0014] Furthermore, the wrench fixing assembly is provided with a first limiting hole, and the wrench movable clamping assembly is provided with a limiting bolt on the side away from the wrench clamping cavity. The limiting hole is used to accommodate the limiting bolt moving in the first limiting hole.

[0015] Furthermore, the wrench clamping cavity is a hexagonal hollow cavity.

[0016] Furthermore, the wrench fixing clamping part is provided with a movable cavity, which is slidably connected to one end of the wrench movable clamping assembly.

[0017] The beneficial effects of this utility model's adjustable wrench are as follows: Due to the design of a wrench fixing component, a wrench movable clamping component is also provided on the wrench fixing component. The wrench movable clamping component is C-shaped and slidably connected to the wrench fixing component. A second movable clamping part is also provided on the wrench fixing component. The wrench fixing clamping part, the wrench movable clamping component, and the second movable clamping part together form a wrench clamping cavity for accommodating the clamped object. The design of the second movable clamping part increases the contact area between the adjustable wrench and the nut or bolt, thereby reducing slippage. Attached Figure Description

[0023] To better understand the purpose, structure, and function of this utility model, the following description is in conjunction with the appendix. Figures 1 to 5 The present invention provides a more detailed description of an adjustable wrench.

[0024] like Figures 1 to 5 As shown in the figure, an embodiment of the present invention provides an adjustable wrench, which includes a cylindrical rotating handle 100. One end of the rotating handle 100 is rotatably connected to a wrench fixing assembly 200, and a wrench fixing clamping part 210 is fixedly connected to the wrench fixing assembly 200. The wrench fixing assembly 200 also includes a turbine cavity 220, in which a wrench turbine 230 is disposed, and the wrench turbine 230 has external threads.

[0025] In this utility model, the wrench fixing assembly 200 is further provided with a wrench movable clamping assembly 240. The wrench movable clamping assembly 240 is C-shaped and is slidably connected to the wrench fixing assembly 200. The wrench movable clamping assembly 240 is also provided with a plurality of turbine teeth 250. The turbine teeth 250 are engaged with the wrench turbine 230. When the wrench turbine 230 is rotated, the turbine teeth 250 are slidably connected with the wrench turbine 230. The wrench turbine 230 is used to drive the wrench movable clamping assembly 240 and the wrench fixing clamping part 210 to move relative to each other.

[0026] Understandably, the wrench fixing assembly 200 is also provided with a second movable clamping part 260. The wrench fixing clamping part 210, the wrench movable clamping assembly 240 and the second movable clamping part 260 together form a wrench clamping cavity 270, which is used to accommodate nuts or bolts.

[0027] In use, rotating the wrench turbine 230 will drive the turbine gear 250 within the wrench turbine 230.

[0028] The wrench slides upward, thereby moving the movable clamping assembly 240 closer to or away from the fixed clamping part 210. When clamping a nut or bolt near the fixed clamping part 210, the design of the second movable clamping part 260 allows more surfaces of the nut or bolt in the wrench clamping cavity 270 to contact the movable wrench. With a larger contact area, the nut or bolt is less likely to slip when the movable wrench tightens or loosens.

[0029] To further reduce the probability of nut or bolt slippage, a second movable screw 261 is provided on the side of the second movable clamping part 260 away from the wrench clamping cavity 270. The second movable screw 261 has external threads, and the end of the second movable screw 261 away from the second movable clamping part 260 is disposed in the rotating handle 100, which is rotatably connected to the second movable screw 261. The end of the rotating handle 100 connected to the wrench fixing assembly 200 is provided with several limiting grooves 110, and the end of the wrench fixing assembly 200 connected to the rotating handle 100 is provided with several limiting holes. Limiting pins 280 are provided in the limiting holes, and the limiting pins 280 are slidably connected to the limiting grooves 110.

[0030] Understandably, in addition to rotating the hand turbine 230, the rotating handle 100 can also be rotated. Since the second movable screw 261 is threadedly connected to the rotating handle 100, when the rotating handle 100 rotates relative to the wrench fixing assembly 200, the second movable clamping part 260 will move away from or closer to the rotating handle 100. After the wrench movable clamping assembly 240 and the wrench fixing clamping part 210 clamp the nut or bolt, if there is still a gap between the second movable clamping part 260 and the nut or bolt, the rotating handle 100 can be rotated to move the second movable clamping part 260 closer to the nut or bolt, thereby further clamping the nut or bolt and further reducing the possibility of slippage.

[0031] When the rotary handle 100 is rotated, the position of the rotary handle 100 and the wrench fixed clamping part 210 will not change under the combined action of the limiting pin 280 and the limiting groove 110, and only the position of the second movable clamping part 260 will move.

[0032] The wrench movable clamping assembly 240 is provided with a screw cavity 242 for the second movable screw 261 to pass through. This design allows the wrench movable clamping assembly 240 to have a wider range of motion and avoids the influence of the second movable screw 261 on the wrench movable clamping assembly 240.

[0033] The wrench movable clamping assembly 240 is provided with a first movable clamping part 241, which is used to clamp the object being clamped. The first movable clamping part 241 is also provided with a limiting cavity 243, which is used to limit the second movable clamping part 260. This ensures that one end of the second movable clamping part 260 always slides within the limiting cavity 243, preventing the second movable clamping part 260 from moving outside the wrench fixing assembly 200 due to the rotation of the second movable screw 261 or other reasons, thus preventing the failure to clamp the nut or bolt.

[0034] In this invention, the wrench fixing assembly 200 is provided with a first limiting hole 290, and the wrench movable clamping assembly 240 is provided with a limiting bolt 244 on the side away from the wrench clamping cavity 270. The limiting hole is used to accommodate the limiting bolt 244 moving within the first limiting hole 290. Under the combined action of the limiting bolt 244 and the first limiting hole 290, the wrench movable clamping assembly 240 can only move within a limited range where the wrench turbine 230 and the turbine teeth 250 can always contact each other, thus preventing the wrench from failing due to the wrench moving beyond the contact range between the wrench turbine 230 and the turbine teeth 250.

[0035] In some embodiments, the wrench holding cavity 270 is a hexagonal cavity, which allows for more efficient turning of hexagonal nuts or hexagonal bolts.

[0036] In other embodiments, an adjustable wrench is used to adjust the hinge or latch.

[0037] The wrench fixing clamping part 210 is provided with a movable cavity 211, which is slidably connected to one end of the wrench movable clamping assembly 240. This design can increase the movable range of the wrench movable clamping assembly 240.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
