[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and do not limit the present invention.

[0024] Example 1

[0025] Figure 1The diagram shown is a structural diagram of an anti-detachment U-shaped connector according to this utility model, including a U-shaped connector body 1 and an anti-detachment device 2 disposed at the opening of the U-shaped connector body 1. The structure of the anti-detachment device 2 is as follows: Figure 2 As shown, it includes a first anti-detachment pin 21, a second anti-detachment pin 22, a claw 23 disposed on the first anti-detachment pin 21, and a hook 24 disposed on the second anti-detachment pin 22.

[0026] In this embodiment, as Figure 1 , 2 As shown, the first anti-detachment pin 21 is detachably installed on the first end 11 of the U-shaped connector body 1, and the second anti-detachment pin 22 is detachably installed on the second end 12 of the U-shaped connector body 1. The claw 23 on the first anti-detachment pin 21 hooks the hook 24 on the second anti-detachment pin 22, connecting the anti-detachment devices 2 into a whole to block the opening of the U-shaped connector body 1. This ensures that the U-shaped connector will not fall when passing through the lifting ring, etc., thus ensuring safety.

[0027] like Figure 2 As shown, the anti-detachment device 2 also includes a first baffle 25 and a first spring 26 sleeved on the first anti-detachment pin 21. The first baffle 25 is provided with a through hole that mates with the threaded hole of the first end side 11 of the U-shaped connector body 1. The first anti-detachment pin 21 and the first spring 26 are installed on the first end side 11 of the U-shaped connector body 1 by screws.

[0028] like Figure 2 As shown, the anti-detachment device 2 also includes a second baffle 27 and a second spring 28 sleeved on the second anti-detachment pin 22. The second baffle 27 has a through hole that mates with the threaded hole on the second end side 12 of the U-shaped connector body 1. The second anti-detachment pin 22 and the second spring 28 are installed on the second end side of the U-shaped connector body by screws. The elasticity of the first spring 26 and the second spring 28 ensures a reliable connection between the first anti-detachment pin 21 and the second anti-detachment pin 22.

[0029] To further increase connection reliability, in a preferred embodiment, such as Figure 2 As shown, the end of the first anti-detachment pin 21 has a blind hole 29, and the end of the second anti-detachment pin 22 has a shaft portion 30 that mates with the blind hole. In actual connection, the shaft portion 30 of the end of the second anti-detachment pin 22 is inserted into the blind hole 29 of the end of the first anti-detachment pin 21 to ensure that the first anti-detachment pin 21 and the second anti-detachment pin 22 will not detach during operation.

[0030] like Figure 2As shown, the claw 23 is rotatably mounted on the first anti-detachment pin 21 via the mounting shaft 31 along an axis perpendicular to the first anti-detachment pin 21. The inner arc diameter of the claw 23 is the same as the outer arc diameter of the first anti-detachment pin 21; the outer arc length of the claw is 220°, which allows the claw 23 to fit snugly against the first anti-detachment pin 21 and also provides an anti-detachment function.

[0031] In order to match the claw 23, in a preferred embodiment, the hook 24 is L-shaped and has an anti-detachment function after being connected to the claw 23.

[0032] Example 2

[0033] Figure 3 The diagram shows the structure of a novel multifunctional tooling according to this invention. This tooling includes a first rod 4, a second rod 5, and the anti-detachment U-shaped connector disclosed in Embodiment 1. The first rod 4 and the second rod 5 are detachably connected to both ends of the U-shaped connector body 1 of the anti-detachment U-shaped connector. In actual use, the U-shaped connector body 1 of the anti-detachment U-shaped connector passes through a lifting ring, etc., and the first rod 4 and the second rod 5 are detachably connected to both ends of the U-shaped connector body 1, thus forming a unified whole and ensuring that the tooling will not detach and cause objects to fall, posing a safety risk.

[0034] In a preferred embodiment, the first rod 4 and the second rod 5 are detachably connected to both ends of the U-shaped connector body 1 of the anti-detachment U-shaped connector via threaded engagement. Obviously, the first rod 4 and the second rod 5 can also be detached from both ends 1 of the U-shaped connector body 1 of the anti-detachment U-shaped connector through other detachable connection methods. For example, corresponding ends can be provided with latches and slots, and detachable connection can also be achieved through the engagement of latches and slots. This invention does not impose any limitations on this aspect.

[0035] To enhance grip and prevent slippage, in a preferred embodiment, the handle portions of the first rod 4 and the second rod 5 are covered with antistatic rubber, such as antistatic rubber with a thickness of 2.5mm. This increases user comfort and effectively prevents static electricity buildup. Furthermore, the rubber surface is embossed with a particle size of not less than 0.5mm, which not only makes it more aesthetically pleasing and practical but also significantly improves slip resistance.

[0036] To prevent the tool from accidentally slipping out of one's hand and causing the object to fall and be damaged, in a preferred embodiment, the ends of the first rod 4 and the second rod 5 are also provided with wrist straps 6, which can further ensure the safety of operation in abnormal situations.

[0037] In summary, the anti-detachment U-shaped connector and the novel multi-functional tooling provided by this utility model, through improved design of existing wrenches, integrate fastening and handling functions into one, filling a gap in transfer tooling, optimizing the operation process, and shortening preparation time. At the same time, through multiple safety designs, the safety of the tooling during operation is effectively ensured, safety risks are reduced, and the benefits are significant.

[0038] Although preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will recognize that various modifications, additions, and substitutions are possible, and therefore the scope of the present invention should not be limited to the above embodiments. For those skilled in the art, several modifications can be made without departing from the principles of the present invention, and these modifications should also be considered within the scope of protection of the present invention.
