[0002] A wrench is a tool frequently used in the mechanical field to turn and tighten bolts, nuts, and other objects that are difficult to turn by hand.

[0003] Often, due to limitations in the workspace and environment, the operating space for removing nuts is quite narrow. Existing ordinary wrenches are generally straight-lined, with the wrench head and handle molded as one piece. When encountering particularly confined spaces, they are inconvenient to operate because they cannot flexibly adjust the angle. Traditional wrenches have the following problems: Inconvenient torque control: Traditional wrenches cannot accurately control torque, which can easily lead to damage to screws or nuts; Poor anti-slip performance: When tightening or loosening screws, the wrench is prone to slipping, resulting in inconvenience in operation and even safety hazards. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of wrench with adjustable torque and anti-slip function, so as to solve the problems mentioned in the background art that traditional wrenches cannot accurately control torque, which can easily lead to damage to screws or nuts; and that the wrench is prone to slipping when tightening or loosening screws, which can cause inconvenience in operation or even safety hazards.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel wrench with adjustable torque and anti-slip function, comprising a handle and a control rod rotatably mounted on the handle, wherein the control rod is provided with a disassembly assembly for disassembling a nut, the handle is provided with an adjustment assembly for adjusting torque, the handle is provided with a limiting assembly for limiting the adjustment assembly, the disassembly assembly is provided with a replacement assembly for replacing the wrench head, and a plurality of anti-slip rings are fixedly installed on the axial sidewall of the handle.

[0006] Preferably, the disassembly assembly includes a first chamber formed on the control rod, a connecting shaft fixedly installed on the first chamber, a connecting rod rotatably installed on the axial side wall of the connecting shaft, a fixing block fixedly installed on the first chamber, and mounting grooves formed on both the fixing block and the connecting rod. A locking rod is inserted through the mounting groove, and a wrench head is fixedly installed at one end of the connecting rod.

[0007] Preferably, the adjustment assembly includes two limiting blocks fixedly installed on the inner wall of the control rod. Two first sliding grooves are formed on the axial side wall of the control rod. The handle is slidably connected to the axial side wall of the control rod through the two first sliding grooves. A threaded groove is formed on the inner wall of the handle. A drive disk is fixedly installed on the inner wall of the handle. A base is threadedly connected to the threaded groove. Threaded rods are rotatably installed on the two limiting blocks. The drive disk and the threaded rods are threadedly connected. The threaded rods are fixedly connected to the base. A pressing disk is fixedly installed at one end of the threaded rod. A torque spring is provided between the pressing disk and the fixing block.

[0008] Preferably, the limiting component includes a limiting disc fixedly installed on the axial side wall of the handle, and the control rod has a plurality of limiting holes, one of which is connected to a pin.

[0009] Preferably, the replacement component includes a mounting plate fixedly installed at the lower end of the wrench head. The mounting plate has four second sliding grooves and two fixing holes. A replacement head is slidably installed on the four second sliding grooves. The replacement head has two fixing grooves. An arc-shaped block is slidably installed on each of the two fixing grooves. A miniature spring is provided between the arc-shaped block and the fixing groove.

[0010] Preferably, the size of the arc-shaped block is the same as the size of the fixing hole, and the position of the arc-shaped block is the same as the position of the fixing hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. When the torque of the wrench needs to be adjusted, the handle, drive disc, and threaded rod work together to move the threaded rod forward within the handle. This compresses the torque spring through the compression disc, thereby adjusting the torque and increasing the wrench's torque. This prevents inaccurate torque control, which could easily damage screws or nuts. Once the torque is adjusted to the correct position, inserting the pin into one of the corresponding limit holes will prevent the handle from continuing to rotate and thus changing the torque. The anti-slip ring here prevents the wrench from falling off during rotation, which could cause inconvenience or even safety hazards.

[0013] 2. When the replacement head can be replaced for nuts of different sizes, first insert the replacement head into the mounting plate along the second slide groove, and then the arc-shaped block will enter the fixing hole through the action of the micro spring, thereby fixing the replacement head and the mounting plate together, which can tighten and loosen nuts of different sizes.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: Please refer to Figures 1-3 A novel wrench with adjustable torque and anti-slip function includes a handle 1 and a control rod 11 rotatably mounted on the handle 1. The control rod 11 is provided with a disassembly component 2 for disassembling nuts. The handle 1 is provided with an adjustment component 3 for adjusting torque. The handle 1 is provided with a limiting component 4 for limiting the adjustment component 3. The disassembly component 2 is provided with a replacement component 5 for replacing the wrench head. Several anti-slip rings 6 are fixedly installed on the axial side wall of the handle 1.

[0021] The disassembly assembly 2 includes a first chamber 21 opened on the control rod 11. A connecting shaft 22 is fixedly installed on the first chamber 21. A connecting rod 23 is rotatably installed on the axial side wall of the connecting shaft 22. A fixing block 24 is fixedly installed on the first chamber 21. Both the fixing block 24 and the connecting rod 23 are provided with mounting grooves 25. A locking rod 26 is inserted and connected through the mounting groove 25. A wrench head 27 is fixedly installed at one end of the connecting rod 23.

[0022] The adjustment assembly 3 includes two limiting blocks 31 fixedly installed on the inner wall of the control rod 11. Two first sliding grooves 32 are opened on the axial side wall of the control rod 11. The handle 1 is slidably connected to the axial side wall of the control rod 11 through the two first sliding grooves 32. A threaded groove 33 is opened on the inner wall of the handle 1. A drive disk 34 is fixedly installed on the inner wall of the handle 1. A base 35 is threadedly connected to the threaded groove 33. A threaded rod 36 is rotatably installed on the two limiting blocks 31. The drive disk 34 and the threaded rod 36 are threadedly connected. The threaded rod 36 and the base 35 are fixedly connected. A pressing disk 37 is fixedly installed at one end of the threaded rod 36. A torque spring 38 is provided between the pressing disk 37 and the fixed block 24.

[0023] The limiting component 4 includes a limiting disc 41 fixedly installed on the axial side wall of the handle 1, and a plurality of limiting holes 42 are provided on the control rod 11, with a pin 43 inserted through one of the limiting holes 42.

[0024] In this embodiment: When the torque of the wrench needs to be adjusted, the handle 1 is rotated, causing the handle 1 to drive the drive plate 34. Because the drive plate 34 is threadedly connected to the threaded rod 36, it can drive the threaded rod 36 to move forward within the handle 1, thereby compressing the torque spring 38 through the compression plate 37, thus adjusting the torque and increasing the torque of the wrench. This avoids inaccurate torque control, which could easily lead to damage to the screw or nut. When the rotational torque exceeds the set torque value, the locking rod 26 will deviate from the mounting groove 25. At this time, the connecting rod 23 will contact the inner wall of the control rod 11, making a sound, which informs the operator that the set torque value has been exceeded and work needs to be stopped. After the torque is adjusted to the correct position, the pin 43 is inserted into one of the corresponding limiting holes 42, which can prevent the handle 1 from continuing to rotate and thus changing the torque. The anti-slip ring 6 is used here to prevent the wrench from falling off during rotation, which would cause inconvenience in operation or even safety hazards.

[0025] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 4 The replacement component 5 includes a mounting plate 51 fixedly installed at the lower end of the wrench head 27. The mounting plate 51 has four second sliding grooves 52 and two fixing holes 53. A replacement head 54 is slidably installed on the four second sliding grooves 52. The replacement head 54 has two fixing grooves 55. An arc-shaped block 56 is slidably installed on each of the two fixing grooves 55. A miniature spring 57 is provided between the arc-shaped block 56 and the fixing groove 55.

[0026] The size of the arc-shaped block 56 is the same as the size of the fixing hole 53, and the position of the arc-shaped block 56 is the same as the position of the fixing hole 53. When the replacement head 54 is inserted into the mounting plate 51, the arc-shaped block 56 enters the fixing hole 53 through the miniature spring 57, thereby fixing the replacement head 54 on the mounting plate 51, which makes it easy to replace the replacement head 54 according to different types of nuts.

[0027] In this embodiment: When the replacement head 54 can be replaced for nuts of different sizes, the replacement head 54 is first inserted into the mounting plate 51 along the second slide groove 52. Then the arc-shaped block 56 will enter the fixing hole 53 through the action of the micro spring 57, thereby fixing the replacement head 54 and the mounting plate 51 together, which can tighten and loosen nuts of different sizes.
