Description

Technical Field

[0001] The utility model relates to a concealed screwdriver wrench, belonging to the technical field of wrenches. Background Art

[0002] At present, in families, factories and repair shops, the disassembly and assembly of machinery mainly rely on manual wrenches. There are three types of wrenches on the market currently: fixed wrenches, adjustable wrenches, and ratchet wrenches. The fixed wrench has a simple structure and single function. It can only be used for specific screw models. Generally, it appears on the market in the form of a series set. It is heavy and the operation is relatively complicated. The adjustable wrench improves the applicable range of the fixed wrench to a certain extent, but the action of disassembling and assembling screws cannot be carried out smoothly, and the work is relatively complicated. The ratchet wrench has the highest working efficiency. It uses a reciprocating swinging translational motion to turn the nut, but in the process of the reciprocating motion of the wrench, half of the work done by the arm is still useless work.

[0003] When the existing wrenches are actually in use, if a narrow and long assembly scenario is encountered during the assembly process, at this time, the operator's hand cannot drive the wrench into the assembly scenario for assembly. Therefore, ordinary wrenches cannot be used for the above-mentioned assembly scenarios, which will affect the assembly efficiency. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a concealed screwdriver wrench.

[0005] In order to achieve the above purpose, the utility model is realized through the following technical solutions:

[0006] A concealed screwdriver wrench includes a sleeve and an L-shaped fixing plate. The sleeve and the L-shaped fixing plate are fixedly connected. A rotating rod is rotatably connected inside the sleeve. One end of the rotating rod penetrates to the outside of the sleeve and a clamping hole is formed on the outer surface. The other end of the rotating rod penetrates to one side of the L-shaped fixing plate and is connected with a first bevel gear. A second bevel gear is rotatably connected to the other side of the L-shaped fixing plate. The second bevel gear meshes with the first bevel gear. The end of the second bevel gear penetrates to the outside of the L-shaped fixing plate and is connected with a clamping member. The clamping member matches the clamping hole.

[0007] Furthermore, a fixing block is arranged on one side of the surface of the clamping member. A fixing groove is formed on the inner wall of one side of the clamping hole. The end of the fixing block is slidably connected in the fixing groove.

[0008] Furthermore, a first rotating hole matching the first bevel gear is formed on one side of the L-shaped fixing plate, and a second rotating hole matching the second bevel gear is formed on the other side of the L-shaped fixing plate.

[0009] Advantages of the Utility Model

[0010] With the setting of this device, screws can be installed and disassembled using two devices with the same structure in a narrow and long assembly environment, which has a wide range of applicability and also improves the usage efficiency of the wrench.

[0011] By the cooperative use of the fixing block and the fixing groove, the end of the fixing block is slidably connected in the fixing groove, enabling the connection between two identical devices, and thus driving the operation of another device when one device rotates.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0018] Please refer to Figures 1-3, the present utility model provides a technical solution for a concealed screwdriver wrench. A concealed screwdriver wrench includes a sleeve 1 and an L-shaped fixing plate 2. The sleeve 1 and the L-shaped fixing plate 2 are fixedly connected to each other. A rotating rod 3 is rotatably connected inside the sleeve 1. One end of the rotating rod 3 penetrates to the outside of the sleeve 1 and a clamping hole 4 is formed on its outer surface. The other end of the rotating rod 3 penetrates to one side of the L-shaped fixing plate 2 and is connected with a first bevel gear 5. A second bevel gear 6 is rotatably connected to the other side of the L-shaped fixing plate 2. The second bevel gear 6 meshes with the first bevel gear 5. The end of the second bevel gear 6 penetrates to the outside of the L-shaped fixing plate 2 and is connected with a clamping member 7. The clamping member 7 matches the clamping hole 4. Through the setting of this device, screws can be installed using two devices with the same structure in a narrow and confined assembly environment, with wide applicability and improved usage efficiency of the wrench.

[0019] Refer to Figures 1-3 , on one side of the surface of the clamping member 7, there is a fixing block 8. A fixing groove 9 is formed on one inner wall of the clamping hole 4. The end of the fixing block 8 is slidably connected in the fixing groove 9. The cooperation of the fixing block 8 and the fixing groove 9 enables the connection between two identical devices, and thus when one device is rotated, it can drive the other device to operate.

[0020] Refer to Figures 1-3 , on one side of the L-shaped fixing plate 2, there is a first rotation hole that matches the first bevel gear 5, and on the other side of the L-shaped fixing plate 2, there is a second rotation hole that matches the second bevel gear 6.

[0021] During use, two completely identical devices A and B can be taken out in advance. Align the clamping member 7 in device A with the screw hole that needs to be disassembled or installed. Hold the sleeve 1 of device A. Subsequently, insert the clamping member 7 on device B into the clamping hole 4 on device A (the clamping members 7 and the clamping holes 4 of devices A and B match each other). Then, hold the sleeve 1 in device B and rotate the sleeve 1. The rotation of the sleeve 1 drives the L-shaped fixing plate 2 in device B to rotate. The rotation of the L-shaped fixing plate 2 drives the second bevel gear 6 and the clamping member 7 on the L-shaped fixing plate 2 to rotate. The clamping member 7 on device B rotates in the clamping hole 4 in device A, and thus can drive the rotating rod 3 in device A to rotate. The rotation of the rotating rod 3 in device A drives the first bevel gear 5 connected thereto to rotate. The rotation of the first bevel gear 5 drives the second bevel gear 6 meshing therewith to rotate. The second bevel gear 6 drives the clamping member 7 connected thereto to rotate. The rotation of the clamping member 7 in device A can drive the screw to rotate, and thus the screw can be disassembled and installed.

[0022] Although this specification is described in terms of embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
