Description

Technical Field

[0001] This utility model relates to the technical field of screwdrivers, specifically to a simple bending screwdriver. Background Technology

[0002] In many repair scenarios, screws are often located in awkward positions, such as deep within engine blocks or large mechanical frames. The handle of a regular screwdriver might hit the hole wall, making it impossible to press down vertically and rotate. Alternatively, there might be a beam, a wiring harness, or a bracket directly above the screw, leaving only a narrow gap on one side. Therefore, screwdrivers designed to handle these scenarios are needed, allowing the handle to rotate on a flat surface without obstructions, while the cutting head works on another surface below, avoiding obstacles. Utility Model Content

[0003] This invention proposes a simple bending screwdriver that can be bent into an L-shaped, Z-shaped, or U-shaped structure to adapt to more usage scenarios with obstacles.

[0004] Therefore, the technical solution adopted is as follows: A simple bending screwdriver includes a working rod and a handle. A connecting rod is fixed to the connecting end of the working rod and the handle. The handle has a connecting groove on a corresponding end face for inserting the connecting rod, and a notch is also formed on the other end face of the handle, the depth of which is less than the depth of the connecting groove. The connecting rod is connected to the handle by a connecting shaft, which passes through the two side walls of the notch, allowing the connecting rod to rotate within the notch. Adjustment holes are correspondingly formed on both side walls for the connecting shaft to slide along the handle's axis. The two ends of the connecting shaft pass through the adjustment holes on both sides and are respectively fixed with a pressing part and a locking part. There is a compression spring sleeved on the connecting shaft between the pressing part and the side wall where the adjacent adjustment hole is located. On the side wall where the adjustment hole is located, there are several limiting grooves along the adjustment hole corresponding to the locking part. The locking part can be embedded in each limiting groove. When the locking part is embedded in the limiting groove closest to the bottom of the connecting groove, the insertion end of the connecting rod is lower than the bottom surface of the notch. When the locking part is embedded in the other limiting grooves, the insertion end of the connecting rod is higher than the bottom surface of the notch.

[0005] A further technical solution is that the working rod includes a rod body and a connecting part. The connecting rod is fixed on the connecting part. The connecting part has an insertion groove at the other end relative to the connecting rod. A sliding block is slidably inserted into the insertion groove. An elastic element is connected between the sliding block and the bottom of the insertion groove. A sliding rod is fixed coaxially with the connecting rod on the bottom surface of the insertion groove. The other end of the sliding rod passes through the sliding block and is slidably connected to it. The end of the sliding rod is hinged to the rod body. When the elastic element is not subjected to external force, it presses the sliding block against the hinged end of the rod body. The edges of the hinged end are all rounded.

[0006] A further technical solution is that the working end of the working rod is provided with a bit groove.

[0007] A further technical solution is that the handle is composed of a working part connected to the working rod and a storage part threadedly connected, and the storage part has a number of bit placement slots inside.

[0008] A further technical solution is that a limiting block is fixed at the opening of the insertion groove, and a limiting boss is fixed on the outer edge of the sliding block, wherein the diameter of the limiting boss is larger than the diameter of the limiting block.

[0009] A further technical solution is that the number of limiting grooves is two, and they are located at both ends of the adjustment hole respectively.

[0010] A further technical solution is that the hinge end of the rod is a cuboid structure in which the distance from the hinge axis to each end face is equal.

[0011] The working principle and beneficial effects of this application are as follows: 1. In addition to its regular use, this screwdriver can be bent into an L-shape and its length can be adjusted by changing the position of the connecting shaft, adapting to more usage scenarios and needs. When you need to quickly turn the screw, you can rotate the working rod to be collinear with the handle. When you need to tighten or loosen the screw, you can rotate the working rod to be perpendicular to the handle, making it more labor-saving.

[0012] 2. At the same time, the screwdriver can also be bent into a Z-shaped or U-shaped structure to solve multiple obstacles in positions such as corners. For example, when the screw that needs to be accessed is located at a specific depth in a narrow space, and there are obstacles on the side of the screw at this depth, the Z-shape can produce a precise lateral offset at a specific depth position, to deal with more narrow scenarios and to assist operators.

[0016] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0017] like Figures 1-8 As shown, a simple bending screwdriver can be bent into various shapes in addition to conventional operation to meet more usage needs. It includes a working rod 1 and a handle 2. A connecting rod 11 is fixed at the connection end of the working rod 1 and the handle 2. The handle 2 has a connecting groove 21 on the corresponding end face for the connecting rod 11 to be inserted. At the same time, a notch 22 is also opened on the other end face of the handle 2. The depth of the notch 22 is lower than the depth of the connecting groove 21. Therefore, when the connecting rod 11 is inserted into the bottom of the connecting groove 21, it cannot rotate. However, when it is pulled out a certain distance and is higher than the bottom of the notch 22, it can rotate in the notch 22.

[0018] Thus, the connecting rod 11 is connected to the handle 2 via a connecting shaft 3. The connecting shaft 3 passes through the two side walls of the notch 22, allowing the connecting rod 11 to rotate within the notch 22. Adjusting holes 30 are correspondingly provided on both side walls for the connecting shaft 3 to slide along the axis of the handle 2. Both ends of the connecting shaft 3 pass through the adjusting holes 30 on both sides and are respectively fixed with a pressing part 31 and a locking part 32. The pressing part 31 and the side wall where the adjacent adjusting hole 30 is located are fitted together. On the side wall of the compression spring 33 on the shaft 3, opposite to the adjustment hole 30, there are several limiting grooves 34 opened along the locking part 32 corresponding to the adjustment hole 30. The locking part 32 can be embedded in each limiting groove 34. When the locking part 32 is embedded in the limiting groove 34 closest to the bottom of the connecting groove 21, the insertion end of the connecting rod 11 is lower than the bottom surface of the notch 22. When the locking part 32 is embedded in the other limiting grooves 34, the insertion end of the connecting rod 11 is higher than the bottom surface of the notch 22.

[0019] When the screwdriver is in its normal position, the insertion end of the connecting rod 11 is lower than the bottom surface of the notch 22. At this time, the connecting rod 11 is restricted by the connecting groove 21 and can only slide axially, not rotate in other directions. When bending is required, pressing the pressing part 31 compresses the spring 33, which pushes the connecting shaft 3 to disengage the locking part 32 at the other end from the lowest position of the limiting groove 34. After disengaging, it continues to grip the pressing parts 31 and locking parts 32 at both ends, causing the connecting shaft 3 to slide along the adjusting hole 30 and enter other limiting grooves. The selection of the groove 34 and the limiting groove 34 determines the final length of the working rod 1. After aligning with the limiting groove 34, the pressing part 31 is released, and the elastic force of the compressed spring 33 causes the locking part 32 to be inserted into the new limiting groove 34 and fixed. At this time, the insertion end of the connecting rod 11 is higher than the bottom surface of the notch 22. Thus, the connecting rod 11 can rotate around the connecting shaft 3 in the notch 22 to drive the working rod 1 to rotate around the handle 2 at a certain angle, forming the first bending joint of the screwdriver. At the same time, the overall length of the working rod 1 can also be adjusted.

[0020] Based on this, the working rod 1 is configured to consist of a rod body 10 and a connecting part 12. The connecting rod 11 is fixed on the connecting part 12. The connecting part 12 has an insertion groove 121 at the other end relative to the connecting rod 11. A sliding block 13 is slidably inserted into the insertion groove 121. A limiting block 122 is fixed at the opening of the insertion groove 121. A limiting boss 131 is fixed on the outer edge of the sliding block 13. The diameter of the limiting boss 131 is larger than the diameter of the limiting block 122, which is used to limit the sliding block 13 and prevent it from coming out of the insertion groove 121. An elastic element 14 is connected between the bottom of the sliding block 13 and the insertion groove 121. A sliding rod 15 is fixed coaxially with the connecting rod 11 on the bottom surface of the insertion groove 121. The other end of the sliding rod 15 passes through the sliding block 13 and is slidably connected to it. The protruding end of the sliding rod 15 is hinged to the rod body 10. When the elastic element 14 is not subjected to external force, it presses the sliding block 13 against the hinge end 16 of the rod body 10. The edges of the hinge end 16 are all rounded corners 161.

[0021] This causes the rod 10 to rotate around the hinge axis. As the hinge end 16 of the rod 10 rotates, it presses against the sliding block 13. The sliding block 13 slides towards the insertion slot 121, pressing against the elastic element 14. After rotation, the elastic element 14 resets, re-clamping the rod 10 and the sliding block 13 together, forming the screwdriver's second bending joint. (See reference...) Figure 7 and Figure 8 This is a schematic diagram of two bending embodiments of the application.

[0022] like Figures 5-6 As shown, the working end of the working rod 1 is provided with a bit groove 17. The handle 2 is composed of a working part connected to the working rod 1 and a storage part 20 connected by threads. The storage part 20 is provided with several bit placement slots 201 inside, which facilitates the replacement and storage of different types of bits.

[0023] One embodiment of the limiting groove 34 is that there are two of them, located at both ends of the adjustment hole 30. This embodiment is suitable for fixed operating environments. The two ends of the limiting adjustment hole 30 make the bending operation simpler, eliminating the need for constant adjustment and ensuring the stability of the elastic force of the compression spring 33. Similarly, the hinge end 16 of the rod body 10 is a cuboid structure that makes the distance from the hinge shaft to each end face equal, which is also to facilitate the stable locking of the elastic element 14 and prevent it from becoming loose or tight due to changes in distance.

[0024] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
