A type of anti-slip wrench

Abstract

This utility model discloses an anti-slip wrench, including a handle, an anti-slip sleeve, a fixed head, a rotating wrench head, and a locking structure. When the rotating wrench head rotates, the rotating pressure plate rotates it into the fixed head. Under the action of a spring, the insertion rod is inserted into the fixed head, and then the positioning block is pressed into the locking groove, limiting the pressure plate. The anti-slip pad is then pressed into the locking groove, and the elastic pressure pad compresses to generate elastic force, thereby positioning the rotating block and ensuring the stability of the rotating wrench head after rotation, preventing wobbling. When adjustment is needed, the push rod is slid to the right by the pull block, causing the insertion rod to slide into contact with the limiting pressure plate. Then, rotating the pressure plate causes the positioning block to move out of the locking groove, making the rotation adjustment of the rotating wrench head convenient and easy.

Description

Technical Field

[0001] This utility model relates to the field of wrench technology, specifically to an anti-slip wrench. Background Technology

[0002] A wrench is a commonly used installation and disassembly tool. It is a hand tool that uses the lever principle to tighten or loosen bolts, screws, nuts and other threaded fasteners. Anti-slip wrenches have anti-slip sleeves on their surfaces to prevent slippage during use.

[0003] Existing anti-slip wrenches have the following problems: To reduce the need to replace wrenches of different sizes, existing anti-slip wrenches are equipped with multiple interchangeable and adjustable wrenches, which are selected by rotating. However, the existing adjustable wrenches are prone to wobbling after adjustment, resulting in instability. Utility Model Content

[0004] The purpose of this invention is to provide an anti-slip wrench to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an anti-slip wrench, comprising a handle, an anti-slip sleeve provided on the handle, a fixed head provided at the end of the handle, a rotating plate head provided in the fixed head, a locking structure provided in the fixed head, the locking structure comprising a rotating block, a rotating block provided on the rotating plate head, a locking groove provided on the rotating block, a pressure plate connected to the fixed head, a spring assembled in the pressure plate, a push rod assembled in the pressure plate, an insert rod provided on the push rod, a pull block provided on the surface of the push rod, and a positioning block provided on the surface of the pressure plate.

[0006] Preferably, the rotating plate head is provided with four wrenches of different sizes, and the rotating block is provided with the same number of slots as the wrenches, and the positions of the slots correspond to the wrenches.

[0007] Preferably, the insertion rod can be inserted into the fixing head.

[0008] Preferably, the pull block protrudes from the surface of the pressure plate, and the surface of the pull block is provided with a pull buckle.

[0009] Preferably, the fixing head is provided with a locking structure at both the front and rear ends, and the locking structure at both ends is identical.

[0010] Preferably, after the pressure plate is inserted into the fixed head, the positioning block abuts against the inside of the slot.

[0011] Preferably, the positioning block has an elastic pad inside, and an anti-slip pad is fixed on the surface of the elastic pad.

[0012] Preferably, the anti-slip pad has a beveled end.

[0013] Compared with the prior art, the beneficial effects of this utility model are: After the rotating plate head rotates, the rotating pressure plate rotates it into the fixed head. Under the action of the spring, the insertion rod is inserted into the fixed head, and then the positioning block is pressed into the slot, limiting the pressure plate. Then the anti-slip pad is pressed into the slot, and the elastic pressure pad is compressed to generate elastic force to position the rotating block, ensuring the stability of the positioning after the rotating plate head rotates and avoiding shaking. When adjustment is needed, the push rod is slid to the right by the pull block, which then drives the insertion rod to slide into contact with the pressure plate limit. Then the pressure plate is rotated to move the positioning block out of the slot, making it convenient and easy to adjust the rotation of the rotating plate head. Attached Figure Description

Detailed Implementation

[0016] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0017] Please see Figure 1 and Figure 2 This utility model provides an anti-slip wrench, including a handle 1, an anti-slip sleeve 2 on the handle 1, a fixed head 3 integrally formed at the end of the handle 1, a rotating plate head 4 rotatably connected in the fixed head head 3, four wrench heads of different sizes on the rotating plate head 4, and a locking structure 5 in the fixed head head 3.

[0018] Specifically, rotate the rotating head 4 to select the appropriate plate opening for the bolt size, then put the plate opening on the bolt, and rotate the handle 1 to tighten the bolt. The anti-slip sleeve 2 provides an anti-slip effect during use.

[0019] Please see Figure 3 , Figure 4 and Figure 5 This utility model provides an anti-slip wrench. The locking structure 5 includes a rotating block 51. The rotating block 51 is fixed on the rotating head 4. The rotating block 51 is located inside the fixed head 3. The rotating block 51 has a slot 52. The number of slots 52 is the same as the number of wrench openings, and the position of the slots 52 corresponds to the wrench openings.

[0020] A pressure plate 53 is rotatably connected to the fixed head 3. A spring 54 is installed in the pressure plate 53. A push rod 55 is installed in the pressure plate 53. The spring 54 is fixed to one end of the push rod 55. An insert rod 56 is fixed to the other end of the push rod 55. The insert rod 56 can be inserted into the fixed head 3 to fix the pressure plate 53 in the fixed head 3. A pull block 57 is provided on the surface of the push rod 55. A positioning block 58 is integrally formed on the surface of the pressure plate 53.

[0021] Among them, the pull block 57 protrudes from the surface of the pressure plate 53, and the surface of the pull block 57 is provided with a pull buckle for easy pulling.

[0022] The fixing head 3 has a locking structure 5 at both the front and rear ends, and the locking structures 5 at both ends are identical.

[0023] After the pressure plate 53 is inserted into the fixed head 3, the positioning block 58 abuts against the inside of the slot 52. An elastic pressure pad 59 is provided inside the positioning block 58, and an anti-slip pad 510 is fixed on the surface of the elastic pressure pad 59. The end of the anti-slip pad 510 is inclined, which allows the positioning block 58 to be inserted into the slot 52 better, and the anti-slip pad 510 abuts against the slot 52, which has a better effect on positioning the rotating block 51.

[0024] Specifically, when the rotating plate head 4 rotates, the rotating pressure plate 53 rotates it into the fixed head 3. Under the action of the spring 54, the insertion rod 56 is inserted into the fixed head 3. Then, the positioning block 58 is pressed into the slot 52, limiting the pressure plate 53. Then, the anti-slip pad 510 is pressed into the slot 52, and the elastic pressure pad 59 is compressed to generate elastic force, so as to position the rotating block 51, ensuring the stability of the positioning after the rotating plate head 4 rotates and avoiding shaking. When adjustment is needed, the push rod 55 is slid to the right by the pull block 57, and then the insertion rod 56 slides to contact the limiting pressure plate 53. Then, the pressure plate 53 is rotated to move the positioning block 58 out of the slot 52, so that the rotating plate head 4 can be adjusted conveniently.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
