Description

Technical Field

[0001] This utility model relates to the field of wrench technology, and more specifically, to a novel multi-functional universal wrench. Background Technology

[0002] A wrench is a commonly used maintenance tool. It is a hand tool that uses the lever principle to tighten or loosen bolts, screws, nuts and other threaded fasteners. Wrenches are usually made of carbon or alloy structural steel. Wrenches usually have openings or sockets for clamping bolts or nuts at one or both ends of the handle. When using a wrench, external force is applied to the handle in the direction of thread rotation to tighten or loosen the bolt or nut.

[0003] In actual use, a normal adjustable wrench or pipe wrench requires a fixed space and angle. However, in actual work, in narrow spaces, other problems often affect normal operation, making it difficult to tighten nuts in narrow spaces in daily operations, thus affecting the practicality of the wrench. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a new type of multi-functional universal wrench to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A novel multi-functional universal wrench includes a wrench body composed of a first handle, a second handle, and a third handle, arranged sequentially from left to right. A grip is fitted onto the outer side of each handle. A retainer is fixedly connected to the outer side of the first handle. A bending assembly is provided between adjacent handles of the first, second, and third handles. Each bending assembly includes a hinge seat fixedly connected to one end of the first and second handles. A connecting shaft is fixedly connected to the other end of the second and third handles. The hinge seats at one end of the first and second handles are rotatably connected to the connecting shafts at the other ends of the second and third handles, respectively. Multiple springs are fixedly connected to the inner side of each hinge seat, and the springs are symmetrically arranged... The springs are arranged on both sides of the hinge base, and a plurality of springs are arranged in a ring array on the surface of the hinge base. Each end of the springs is fixedly connected to a locking block, and the locking block is slidably connected to the inner side of the hinge base. The inner surfaces of the other ends of the second and third wrench handles are provided with a plurality of grooves, and the bottom of each groove is set as an arc. The grooves are arranged in a ring array with the connecting shaft as the center. Two guide grooves are provided on both sides of the first, second, and third wrench handles. A plurality of guide strips are fixedly connected to the inner surface of the handle, and the guide strips are symmetrically distributed on the inner side of the handle. A second guard is fixedly connected to one side of the handle. The second guard has a trapezoidal cross section. A screw is threadedly connected to one side of the handle, and a washer is fixedly connected to the end of the screw. An elastic reset mechanism is provided on one side of the first wrench handle.

[0006] By adopting the above technical solution, the lever arm of the wrench consisting of wrench handle one, wrench handle two, and wrench handle three can be increased by combining the bending of the handle with the sliding of the grip, thereby improving the ease of turning nuts in narrow spaces.

[0007] As a further description of the above technical solution: the elastic reset mechanism includes a jaw hinged to the inner side of the wrench handle, a fixed post fixedly connected to the inner side of the wrench handle, a torsion spring fixedly connected to the outer side of the fixed post, the end of the torsion spring engaging with one side of the jaw, and a plurality of anti-slip protrusions fixedly connected to one side of the wrench handle, and the plurality of anti-slip protrusions being evenly distributed at the end of the wrench handle.

[0008] By adopting the above technical solution, the elastic push of the torsion spring causes the pliers and multiple anti-slip teeth to fit into the surface of the nut to be tightened, thus maintaining the stability of tightening the nut.

[0009] The technical effects and advantages of this utility model are as follows: 1. By setting up a bending component, compared with the existing technology, there is no need to frequently change the extension bar of different lengths or wrenches of various angles. The bending deformation between wrench handle one, wrench handle two and wrench handle three can adapt to multiple angles, optimize the force application posture of tightening the wrench, and at the same time, by utilizing the sliding of the handle, wrench handle one, wrench handle two and wrench handle three can be fixed and the lever arm can be increased, reducing the time for tool switching and finding the best angle, improving spatial adaptability and ease of use; 2. By setting up an elastic reset mechanism, compared with the existing technology, the elastic push of the torsion spring on the jaws enables the jaws to maintain effective contact with the nut to be tightened. Combined with the anti-slip teeth, slippage is avoided during tightening, thus improving the stability of tightening the nut. Attached Figure Description

[0021] 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.

[0022] The embodiments disclosed in this application are as follows: Figures 1-10 The present invention discloses a novel multi-functional universal wrench, comprising a wrench body, which is composed of a wrench handle 1, a wrench handle 2, and a wrench handle 3, arranged sequentially from left to right. A handle 5 is sleeved on the outer side of each of the wrench handles 1, 2, and 3. A retainer 4 is fixedly connected to the outer side of the wrench handle 1. Bending components are provided between adjacent wrench handles 1, 2, and 3. Each bending component includes a hinge seat 6 fixedly connected to one end of the wrench handle 1 and the wrench handle 2. A connecting shaft 9 is fixedly connected to the other end of the wrench handle 2 and one end of the wrench handle 3. The hinge seats 6 at one end of the wrench handle 1 and the wrench handle 2 are rotatably connected to the connecting shaft 9 at the other end of the wrench handle 2 and the other end of the wrench handle 3. Multiple springs 7 are fixedly connected to the inner side of the hinge seats 6. Symmetrically arranged on both sides of the hinge seat 6, multiple springs 7 are arranged in a ring array on the surface of the hinge seat 6. Each end of the multiple springs 7 is fixedly connected to a locking block 8, and the locking block 8 is slidably connected to the inner side of the hinge seat 6. Multiple grooves are opened on the inner surfaces of the other end of the wrench handle 2 and the other end of the wrench handle 3, and the bottom of the multiple grooves is set as an arc. The multiple grooves are arranged in a ring array with the connecting shaft 9 as the center. Two guide grooves 10 are opened on both sides of the wrench handle 1, wrench handle 2 and wrench handle 3. Multiple guide strips 11 are fixedly connected to the inner surface of the handle 5, and the multiple guide strips 11 are symmetrically distributed on the inner side of the handle 5. A second guard 12 is fixedly connected to one side of the handle 5. The cross section of the second guard 12 is trapezoidal. A screw 13 is threadedly connected to one side of the handle 5. A washer 14 is fixedly connected to the end of the screw 13. An elastic reset mechanism is provided on one side of the wrench handle 1. By utilizing the bending of wrench handle 1, wrench handle 2, and wrench handle 3, nuts in narrow areas can be tightened. At the same time, the sliding of the handle 5 increases the lever arm of the wrench, improving its spatial adaptability. Furthermore, multiple springs 7 and locking blocks 8 inside the hinge seat 6 at one end of wrench handle 1 and wrench handle 2 provide multi-point positioning for multiple connecting shafts 9 at the other end of wrench handle 2 and one end of wrench handle 3. This ensures that the bending of wrench handle 1, wrench handle 2, and wrench handle 3 is properly positioned, preventing easy bending between them and ensuring stable use of the wrench.

[0023] Reference Figure 1 , Figure 4 and Figure 5 As shown, the elastic reset mechanism includes a jaw 17 hinged to the inside of the wrench handle 1. A fixing post 15 is fixedly connected to the inside of the wrench handle 1, and a torsion spring 16 is fixedly connected to the outside of the fixing post 15. The end of the torsion spring 16 is engaged with one side of the jaw 17. Multiple anti-slip teeth 18 are fixedly connected to one side of the wrench handle 1, and the multiple anti-slip teeth 18 are evenly distributed at the end of the wrench handle 1. By utilizing the elastic thrust stored by the deformation of the torsion spring 16, the jaw 17 can press down and fit against the surface of the nut, so that the jaw 17 and the multiple anti-slip teeth 18 at the end of the wrench handle 1 can effectively tighten the nut, preventing the nut from becoming loose.

[0024] The working principle of this utility model is as follows: When turning a valve with a wrench in a narrow space, first swing one side of the jaw 17 towards the wrench handle 1, so that the jaw 17 pushes the torsion spring 16 to deform and compress elastically. Then, the multiple anti-slip protrusions 18 at the end of the wrench handle 1 come into contact with the surface of the nut. After that, the torsion spring 16 will restore its elastic deformation and push the jaw 17 to fit against the side of the nut, so that the upper and lower surfaces of the nut come into contact with the jaw 17 and the anti-slip protrusions 18 at the end of the wrench handle 1. Then, turn the screw 13 on one side of the handle 5 outwards, so that the washer 14 at the end of the screw 13 moves towards the handle 5, so that the washer 14 releases the pressure on the side of the wrench handle 1. Then pull the handle 5 outwards along the wrench handle 1, wrench handle 2 and wrench handle 3, and bend the wrench handle 1, wrench handle 2 and wrench handle 3 in a "Z" shape. It is worth noting that by rotating the hinge seat 6 and connecting shaft 9 between the wrench handle 1, wrench handle 2, and wrench handle 3, the wrench handle 1, wrench handle 2, and wrench handle 3 can be bent at different angles. At the same time, multiple springs 7 on both sides of the hinge seat 6 at the ends of the wrench handle 1 and wrench handle 2 push the locking block 8 to elastically engage multiple connecting shafts 9 at the other end of the connected wrench handle 2 and one end of the connected wrench handle 3. Meanwhile, the arc-shaped bottom surface of the multiple connecting shafts 9 allows the multiple locking blocks 8 to smoothly engage and disengage among the multiple connecting shafts 9. This provides a certain resistance to the bending of the wrench handle 1, wrench handle 2, and wrench handle 3, preventing the wrench handle 1, wrench handle 2, and wrench handle 3 from bending easily. At the same time, after the handle 5 slides to the outside of the wrench handle 3, the screw 13 on the outside of the handle 5 is turned inward, thereby driving the pad 14 to press and position the side of the wrench handle 3, thereby increasing the length between the wrench handle 1, wrench handle 2, wrench handle 3 and the handle 5, and increasing the lever arm of the wrench. It is worth noting that by using the grip 5 to connect the wrench handle 1, wrench handle 2, and wrench handle 3, the guard 2 12 at the end of the grip 5 guides the bent wrench handle 1, wrench handle 2, and wrench handle 3 at an angle, so that the wrench handle 1, wrench handle 2, and wrench handle 3 are reguided to be vertical. The grip 5 can be used to position the wrench handle 1, wrench handle 2, and wrench handle 3, assisting in the restoration of the wrench handle 1, wrench handle 2, and wrench handle 3, and improving the wrench's performance.
