[0028] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0029] In order to solve the technical problem that the positioning bar is fixedly connected to one clamp handle and passed through another clamp handle, which is inconvenient for users to hold and relatively inconvenient to operate, the utility model provides an anti-loosening pliers, which can prevent loosening while making it convenient for users to hold the handle to clamp materials, thereby improving user experience.

[0030] See also Figure 1 and Figure 2 , Figure 1 and Figure 2 This is a structural schematic diagram of an anti-loosening pliers in an embodiment of the utility model. The anti-loosening pliers include a locking structure 3, two pliers bodies 1 and two mounting seats 2; each pliers body 1 includes a handle 11, a rotating section 12 and a pliers head 13 connected in sequence, and the two rotating sections 12 are rotatably connected; the two mounting seats 2 are detachably mounted on the two handles 11 respectively; the locking structure 3 connects the two mounting seats 2, and when the mounting seats 2 are mounted on the handles 11, it has a first state in which the two mounting seats 2 are locked and a second state in which the two mounting seats 2 are unlocked. In the first state, the locking structure 3 can limit the relative rotation of the two rotating sections 12 through the two mounting seats 2, and in the second state, the two rotating sections 12 can rotate relative to each other.

[0031] The anti-loosening pliers provided by the utility model have two mounting seats 2 that are detachably mounted on two handles 11. Thus, before using the pliers body 1 to clamp materials, the two mounting seats 2 are first detached from the corresponding handles 11 to facilitate user gripping, and the locking structure 3 is switched to an unlocked state; and after the pliers body 1 clamps the material, the two mounting seats 2 are then mounted on the two handles 11, and the locking structure 3 is switched to a locked state to prevent the two rotating sections 12 from rotating relative to each other, thereby achieving anti-loosening. While achieving anti-loosening, this solution also facilitates users to grip the handles 11 to clamp materials, thereby improving user experience. It should be understood that the specific structure and principle of the rotating section 12 are prior art and will not be elaborated on here.

[0032] It should be noted that, in one embodiment, an avoidance hole is provided on the mounting seat 2, and the locking structure 3 is provided in the form of a positioning strip and a locking pin. One end of the positioning strip is fixedly connected to another mounting seat 2, and the other end is passed through the avoidance hole. The locking pin can extend into the avoidance hole to lock the positioning strip, and the positioning strip is provided in an arc shape.

[0033] In one embodiment, see Figure 2 and Figure 3 The locking structure 3 includes an outer ring 31, an inner ring 32, a locking screw 33 and two locking nuts 34. The outer ring 31 is rotatably mounted on the mounting seat 2 around an axis located in a first direction, and the inner ring 32 is rotatably mounted on the outer ring 31 around an axis located in a second direction. The first direction intersects with the second direction. One end of the locking screw 33 is rotatably mounted on the other mounting seat 2, and the other end is penetrated through the inner ring 32. The two locking nuts 34 are threaded on the locking screw 33 and are located on both sides of the inner ring 32 in the axial direction.

[0034] In this embodiment, the two handles 11 are locked by adjusting the distance between the two locking nuts 34 and the inner ring 32. The operation is simple and convenient. After the locking is achieved, the locking nuts 34 and the locking screws 33 can be used to effectively prevent loosening, and the stability is good. It should be noted that in this embodiment, the first direction is perpendicular to the second direction, and the outer ring 31 and the inner ring 32 form a universal joint.

[0035] In one embodiment, the mounting seat 2 is provided with a mounting hole 2a along the axial direction of the locking screw 33, and the outer ring 31 is rotatably mounted on the inner wall of the mounting hole 2a around an axis located in the first direction.

[0036] In this embodiment, the outer ring 31 is arranged in the mounting hole 2a of the mounting seat 2, so that the overall structure is more compact. It should be understood that in order to increase the degree of freedom of the inner ring 32, the inner diameter of the mounting hole 2a is set larger to reduce the probability of interference between the outer ring 31 and the mounting seat 2 during rotation, and at the same time reduce the thickness of the mounting seat 2 corresponding to the mounting hole 2a.

[0037] In one embodiment, each mounting seat 2 is provided with a socket 2b, and the socket 2b is for the corresponding handle 11 to be inserted, so that the mounting seat 2 can be detachably mounted on the handle 11. In this embodiment, the handle 11 is inserted into the socket 2b of the mounting seat 2 through the socket 2b, which is simple and convenient to operate, easy to process and produce, and saves costs.

[0038] In one embodiment, one of the mounting base 2 and the handle 11 is provided with a magnetic attraction portion, and the other is provided with an attraction portion attracted to the magnetic attraction portion, so that the mounting base 2 is magnetically attracted to the handle 11 .

[0039] In this embodiment, the magnetic attraction portion cooperates with the adsorption portion, so that the mounting base 2 can be stably mounted on the handle 11, thereby improving the connection stability between the mounting base 2 and the handle 11. Specifically, in this solution, the mounting base 2 is made of a magnetic material to form the magnetic attraction portion, and correspondingly, the handle 11 is made of a magnetic material to form the adsorption portion.

[0040] In one embodiment, see Figure 4 One of the inner wall of the insertion hole 2b and the handle 11 is provided with a limiting protrusion, and the other is provided with a limiting groove for the limiting protrusion to be slidably inserted, and the limiting protrusion and the limiting groove extend along the axial direction of the insertion hole 2b.

[0041] In this embodiment, when the handle 11 is inserted into the insertion hole 2b, the limiting protrusion 111 slides into the limiting groove 2c, and the cooperation between the limiting protrusion 111 and the limiting groove 2c can prevent the mounting base 2 from rotating relative to the handle 11, thereby improving stability. Specifically, in this solution, the limiting protrusion 111 is formed on the handle 11, and the limiting groove 2c is formed in the insertion hole 2b.

[0042] In one embodiment, the opening end of the insertion hole 2b is gradually expanded in a direction close to the handle 11.

[0043] In this embodiment, the opening end of the insertion hole 2b is set to be gradually expanded to form a bell mouth 2d, so that the handle 11 can enter the insertion hole 2b, play a guiding role, and improve convenience.

[0044] In one embodiment, the anti-loosening pliers further include a connecting rope 4, the connecting rope 4 connects the two mounting seats 2, and the length of the connecting rope 4 is greater than the distance between the two handles 11 when they are at the maximum opening and closing degree.

[0045] In this embodiment, the two mounting seats 2 are connected by a connecting rope 4, and the connecting rope 4 is set to be larger than the maximum opening and closing distance of the two handles 11, so as to ensure that the opening and closing degree of the pliers head 13 can be freely adjusted, and at the same time, the two mounting seats 2 can be connected by the connecting rope 4 when the mounting seat 2 is detached from the handle 11 to avoid loss.

[0046] In one embodiment, see Figure 5 One of the two mounting seats 2 is provided with an assembly screw hole 2e, and the other is provided with an assembly screw rod 21. The assembly screw rod 21 is screwed into the assembly screw hole 2e when the mounting seat 2 is detached from the handle 11.

[0047] In this embodiment, when the mounting seat 2 is detached from the handle 11, the two mounting seats 2 can be screwed together by matching the mounting screw rod 21 with the mounting screw hole 2e for easy transportation.

[0048] In one embodiment, one end of the assembly screw rod 21 extending into the assembly screw hole 2e is spaced apart from the bottom wall of the assembly screw hole 2e to form an accommodating cavity 2f.

[0049] In this embodiment, a receiving chamber 2f is formed between the assembly screw rod 21 and the assembly screw hole 2e to store objects, specifically, the locking nut 34 and the connecting rope 4, thereby improving practicality.

[0050] In order to better understand the present invention, the following Figures 1 to 5 The technical solution of the utility model is described in detail:

[0051] Before using the pliers body 1 to clamp the material, the two mounting seats 2 are first detached from the corresponding handles 11 to facilitate the user's grip, and the spacing of the locking nuts 34 is adjusted to the maximum; and after the pliers body 1 clamps the material, the two mounting seats 2 are installed on the two handles 11, and the two locking nuts 34 are adjusted to the positions against the opposite sides of the inner ring 32, respectively, to prevent the two rotating sections 12 from rotating relative to each other, thereby preventing them from loosening.

[0052] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
