At the same time, during the assembly and processing, the rotating rod 4 can be held and rotated downward, and the rotating rod 4 will drive the single-threaded rod 5 to rotate synchronously, so that the single-threaded rod 5 drives the rubber anti-sliding block 6 to move downward, thereby increasing the friction through the rubber anti-sliding block 6 and improving the overall stability.

[0030] See also Figure 1 , Figure 2 and Figure 3 The upper end of the single threaded rod 5 is welded with a rotating rod 4, and the lower end of the single threaded rod 5 is provided with a rubber anti-sliding block 6. The setting of the rotating rod 4 is convenient for the user to rotate the single threaded rod 5, and the rubber anti-sliding block 6 can increase the friction with the ground and improve stability;

[0031] See also Figure 2 and Figure 5Three equally spaced second guide rods 16 are welded inside the L-shaped block 14, and the second guide rods 16 all penetrate the clamping block 15, and the second guide rods 16 are slidably matched with the clamping block 15, and the second guide rods 16 are sleeved with a return spring 17 outside, one end of the return spring 17 is connected to the L-shaped block 14, and the other end of the return spring 17 is connected to the clamping block 15, and the elastic action of the return spring 17 enables the clamping block 15 to clamp and fix the sprocket;

[0036] Working principle: When in use, the crawler sprocket is assembled and installed. First, pull one of the pull blocks 18. The pull block 18 will drive the clamping block 15 to move synchronously, and the movement of the clamping block 15 will stretch the reset spring 17. Put one end of the sprocket to be aligned and assembled between the clamping block 15 and the L-shaped block 14. After releasing the pull block 18, the position of the clamping block 15 can be restored under the elastic recovery action of the reset spring 17, so that the clamping block 15 can be moved backward to clamp and fix the middle sprocket. At this time, in order to improve the stability during clamping, the user can turn the knob 20, and the knob 20 will drive the rotating shaft 19 to rotate. The rotating shaft 19 will drive the double-threaded transmission rod 11 to rotate synchronously. The double-threaded transmission rod 11 will drive the two moving blocks 13 to rotate synchronously. Since one end of the moving block 13 is slidably matched with the first guide rod 12, the moving blocks 13 will be axially limited. The rotation of the moving block 13 will be converted into horizontal movement in the opposite or same direction, so that the two moving blocks 13 move toward each other, so that the clamping block 15 on the other side can clamp and fix the other end of the sprocket, which can improve the stability during the assembly process after alignment. The user can grasp the handle 9 to move the base 1, so that the fixed sprocket can be aligned with the corresponding position in the crawler sprocket system, so as to perform alignment and assembly. The fixed seat 8 is moved upward by starting the electric telescopic rod 7, so that the sprocket can be height-adjusted in the vertical direction, which increases the range of the alignment position and has good practicality. During the alignment process, the rotating rod 4 can be grasped, and the rotating rod 4 will drive the single-threaded rod 5 to rotate, so that the single-threaded rod 5 moves downward, thereby driving the rubber anti-slip block 6 at the lower end of the single-threaded rod 5 to contact the ground. The rubber anti-slip block 6 can increase the friction with the ground, thereby increasing the stability after alignment and facilitating the alignment process.
