Description

Technical Field

[0001] The present application belongs to the field of wrenches, and in particular to an anti-slip wrench. Background Art

[0002] In the field of mechanical assembly, a wrench is a commonly used installation and removal tool. It mainly includes an open end that matches with fasteners such as bolts, screws and nuts, and a handle connected to the open end. When in use, the open end is put on the fastener, and the handle is twisted using the principle of leverage to achieve the installation and removal of these fasteners.

[0003] The existing publication number is CN110370210B, which discloses a wrench changing device, including a handle, a connecting assembly and two locking assemblies. The connecting assembly includes a wrench sleeve and a connecting piece, and the connecting piece and the handle are installed together through a fixing piece.

[0004] Although the above-mentioned wrench can be used to tighten fasteners in a narrow space, it is easy to slip out of the hand when in use, has a weak anti-slip ability, and poses a safety hazard when in use. Utility Model Content

[0005] The purpose of this application is to provide an anti-slip wrench to address the above-mentioned technical problems, so that the wrench is not easy to slip out of the hand when in use, has strong anti-slip ability, and reduces the safety hazards when using the wrench.

[0006] The present application provides an anti-slip wrench, comprising a handle body, a wrench head, and further comprising:

[0007] An anti-slip component, wherein the anti-slip component is mounted on the handle body;

[0008] A fixing assembly, wherein the fixing assembly is mounted on the handle body;

[0009] A steering assembly, wherein the steering assembly is mounted on the handle body;

[0010] Wherein, the fixing assembly includes a lifting assembly, a fixing piece, a fixing groove, and a fixing layer. The lifting assembly is installed on the handle body, the fixing piece is installed on the lifting assembly, the fixing groove is arranged on the fixing piece, and the fixing layer is installed on the fixing piece.

[0011] When holding the wrench, the lifting assembly drives the fixing part downward until the fixing layer on the fixing part fits with the user's hand to complete the fixation. When the fixation needs to be cancelled, the lifting assembly drives the fixing part upward to cancel the fixation of the user's hand. The fixing layer is made of memory foam to avoid pinching the user's hand. The fixing assembly can prevent the wrench from slipping out of the hand easily when in use, has strong anti-slip ability, and reduces safety hazards when using the wrench.

[0012] Furthermore, the lifting assembly includes:

[0013] A lifting base, the lifting base is mounted on the handle body; the lifting base is provided with a threaded hole;

[0014] A lifting rod, the lifting rod is installed on the lifting base, and the lifting rod is provided with a thread;

[0015] A bearing, wherein the inner ring of the bearing is connected and installed with the lifting rod, and the outer ring of the bearing is installed on the installation groove;

[0016] A drive assembly is mounted on the fixing groove.

[0017] The lifting assembly can drive the fixing part to move down or up, thereby determining the locking and unlocking of the hand of the user holding the wrench. When the user's hand needs to be locked, the driving assembly drives the lifting rod to move up and down in the lifting base. The lifting base and the lifting rod are installed with threads. When the driving assembly drives the lifting rod to rotate, the inner ring of the bearing also rotates with the lifting rod, and the outer ring of the bearing is connected to the installation groove and installed without rotating. The lifting rod rotates in the lifting base to engage the thread with the threaded hole, so that the lifting rod moves up or down, so that the fixing part is more accurate when descending to perform locking work, and the user's hand is prevented from being pinched due to excessive descending distance, so that the safety and stability of the locking assembly are significantly improved.

[0018] Furthermore, the driving assembly includes:

[0019] A rotating shaft, wherein the rotating shaft is installed in the fixing groove;

[0020] A motor, wherein the motor is mounted on the first rotating shaft;

[0021] A first bevel gear, wherein the first bevel gear is mounted on the rotating shaft;

[0022] A second bevel gear is mounted on the lifting rod, and the second bevel gear is meshed with the first bevel gear.

[0023] When the driving assembly is needed to drive the lifting rod to rotate, the motor is started, the motor drives the rotating shaft to rotate, the rotating shaft drives the first bevel gear to rotate, the first bevel gear meshes with the second bevel gear to rotate the second bevel gear, the second bevel gear is connected to the lifting rod to drive the lifting rod to rotate for lifting work, and the automatic lifting does not require manual driving of the lifting assembly to work, thereby reducing the labor intensity of the user.

[0024] Furthermore, the lifting assembly further comprises:

[0025] The scale is arranged on the lifting rod.

[0026] The lifting component also includes a scale, which is arranged on the lifting rod. The scale can accurately show the lifting distance when the lifting component is lifted or lowered, so that the user can control the moving position of the fixing part conveniently, so that the lowering and rising distances of the fixing part are more accurate, and the fixing component is more stable and safer when performing fixing work.

[0027] Furthermore, the anti-slip assembly includes:

[0028] An anti-slip groove, the anti-slip groove is arranged on the handle body;

[0029] a spring, wherein the spring is mounted on the anti-slip groove;

[0030] A top block, the top block being mounted on a spring;

[0031] A handle cover is installed on the handle body.

[0032] The anti-slip component provides anti-slip protection when the user holds the wrench. When holding the handle body, the user's hand applies pressure to the top block, and the top block applies pressure to the spring. The spring is a compression spring. After being subjected to pressure, the compression spring will generate a rebound force applied to the user's hand, so that the handle jacket can better fit the user's hand to provide anti-slip protection for the user's hand, and the anti-slip effect of the handle body is better, and it is less likely to slip out of the hand.

[0033] Furthermore, the handle cover is provided with:

[0034] An anti-sliding block is installed on the handle outer cover.

[0035] The handle outer shell is provided with an anti-slip block, which is installed on the handle outer shell. The anti-slip block can provide friction when the user holds the wrench, thereby increasing the anti-slip ability, preventing the wrench from slipping out of the hand and affecting the user's work, and improving the safety of the user using the wrench.

[0036] Furthermore, the steering assembly comprises:

[0037] A first connecting block, the first connecting block is mounted on the handle body, and a through hole is provided on the first connecting block;

[0038] A second connecting block, the second connecting block is mounted on the wrench head, and the second connecting block is provided with a through hole;

[0039] Bolts, the bolts being mounted on the first connecting block and the second connecting block;

[0040] A nut is mounted on the bolt.

[0041] The steering assembly is used to rotate the wrench head, and the angle between the first connecting block and the second connecting block is adjusted, and then fixed using bolts and nuts. The wrench can be adjusted according to different usage scenarios, thereby increasing the adaptability of the wrench in different environments.

[0042] The beneficial effects of this application are:

[0043] 1. The fixing assembly can prevent the wrench from slipping out of the hand during use, has strong anti-slip ability, and reduces potential safety hazards when the wrench is used;

[0044] 2. The lifting rod rotates in the lifting base so that the thread engages with the threaded hole, causing the lifting rod to move up or down, making the fixing more accurate when descending to lock, avoiding the user's hand from being pinched due to the long descent distance, and significantly improving the safety and stability of the locking assembly;

[0045] 3. After being subjected to pressure, the compression spring will generate a rebound force to apply to the user's hand, so that the handle cover can better fit the user's hand and provide anti-slip protection for the user's hand, making the handle body more anti-slip and less likely to slip out of the hand.
