[0030] It should be noted that: during use, the groove on the fixed rod 1 is sleeved outside the corresponding threaded part, and then the rotating member 2 is rotated. Since the rotating member 2 is screwed to the outside of the fixed rod 1, the movement of the rotating member 2 drives the position of the moving member 3 to change. Since the outside of the clamping block 4 abuts against the frustum groove in the moving member 3, a plurality of clamping blocks 4 are driven to move. When the clamping block 4 slides in the fixed rod 1, the connecting plate 42 and the telescopic assembly play a guiding role for the movement of the clamping block 4. When the inner walls of the plurality of clamping blocks 4 abut against the outside of the threaded part, stop rotating the rotating member 2, and then rotate the threaded part by holding the connecting rod 5 by hand. This device can adjust the position of the clamping block 4 according to the size of the threaded part, which is convenient for screwing threaded parts of different sizes.

[0031] In an embodiment of the present utility model, please refer toFigure 1 and Figure 4 As shown in Figure 4 , sliding bars 41 are fixedly connected to both sides of each clamping block 4, and sliding grooves for the sliding bars 41 to slide are formed on both sides of each guiding groove.

[0032] It should be noted that when the clamping block 4 slides in the fixed rod 1, the sliding bar 41 slides on the sliding groove synchronously. Such a design can play a certain guiding role in the movement of the clamping block 4, making the clamping block 4 in a stable state during movement.

[0033] In an embodiment of the present utility model, please refer to Figure 2 and Figure 3 As shown in Figure 3 , the telescopic assembly includes a sleeve 81 fixedly connected to the connecting plate 42. A sliding rod 82 is slidably arranged in the sleeve 81. The sliding rod 82 is fixedly connected to the hexagonal fixed column 43, and a first spring 83 is fixedly connected between the sliding rod 82 and the inner wall of the sleeve 81.

[0034] It should be noted that when the clamping block 4 slides in the fixed rod 1, the sleeve 81 moves under force. At this time, the sliding rod 82 extends into the sleeve 81, and the first spring 83 is in a compressed state. The setting of the telescopic assembly plays a certain guiding role in the movement of the clamping block 4, making the clamping block 4 in a stable state during movement.

[0035] In an embodiment of the present utility model, please refer to Figure 1 and Figure 5 As shown in Figure 5 , a through hole 51 is formed on one side of the connecting rod 5 away from the fixed rod 1. A support rod 6 is arranged in the through hole 51. An installation groove 52 is formed on the connecting rod 5 on one side of the through hole 51. A limiting component for limiting the support rod 6 is arranged in the installation groove 52. The limiting component includes a positioning pin 61 slidably arranged in the installation groove 52. The end of the positioning pin 61 extends into the through hole 51. A push plate 62 is slidably arranged in the installation groove 52. The push plate 62 is fixedly connected to the positioning pin 61. A spring 63 is fixedly connected between the push plate 62 and the inner wall of the installation groove 52. A positioning hole 64 for the positioning pin 61 to be inserted is formed in the middle of the support rod 6.

[0036] It should be noted that during use, by pushing the push plate 62 to slide away from the anti-slip sleeve 7, the spring 63 is in a compressed state at this time. Then, the support rod 6 is inserted into the through hole 51, and the positioning hole 64 on the support rod 6 is aligned with the positioning pin 61. Subsequently, the push plate 62 is released, and the positioning pin 61 pops into the positioning hole 64 under the elastic force of the spring 63, thereby completing the installation of the support rod 6. By rotating the connecting rod 5 through the support rod 6, it is convenient to disassemble bolts or nuts.

[0037] In an embodiment of the present utility model, please refer to Figure 5 As shown in Figure 5 , an anti-slip sleeve 7 is fixedly sleeved on the outer part of one end of the connecting rod 5 away from the fixed rod 1. Anti-slip lines are formed on the anti-slip sleeve 7.

[0038] It should be noted that: The design of the anti-slip sleeve 7 facilitates the user to grip the connecting rod 5. The design of the anti-slip layer can increase the friction between the hand and the anti-slip sleeve 7, and the fixing effect is better.

[0039] The working principle of the present utility model is as follows:

[0040] During use, the groove on the fixing rod 1 is sleeved outside the corresponding threaded part, and then the rotating member 2 is rotated. Since the rotating member 2 is screwed outside the fixing rod 1, the movement of the rotating member 2 drives the position of the moving member 3 to change. Since the outside of the clamping block 4 abuts against the conical groove in the moving member 3, multiple clamping blocks 4 are driven to move. When the clamping block 4 slides in the fixing rod 1, the slide bar 41 slides on the chute synchronously, and the sleeve 81 is forced to move. At this time, the slide rod 82 extends into the sleeve 81, and the first spring 83 is in a compressed state. The slide bar 41 and the telescopic assembly are provided to guide the movement of the clamping block 4. When the inner walls of multiple clamping blocks 4 abut against the outside of the threaded part, stop rotating the rotating member 2, and screw the threaded part by holding the anti-slip sleeve 7 by hand. If the threaded part is difficult to screw, then install the support rod 6. By pushing the push plate 62 to slide towards the side away from the anti-slip sleeve 7, the spring 63 is in a compressed state at this time. Then insert the support rod 6 into the through hole 51, and align the positioning hole 64 on the support rod 6 with the positioning pin 61. Then release the push plate 62, and the positioning pin 61 pops into the positioning hole 64 under the elastic force of the spring 63, thus completing the installation of the support rod 6. The connecting rod 5 is rotated by the support rod 6 to facilitate the disassembly of the threaded part. By rotating the rotating member 2 of the present utility model, the position of the moving member 3 changes, thereby driving the movement of multiple clamping blocks 4 so that the distance between the clamping blocks 4 is adjusted, so that the position of the clamping blocks 4 can be adjusted according to the size of the threaded part, facilitating the screwing of threaded parts of different sizes.

[0041] The above is only the preferred specific embodiment of the present utility model; however, the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
