Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figure 1-6, the present utility model provides a technical solution: a quick positioning device, including a bottom plate 1, a support block 2, a guide rail 3, a guide sleeve 4, a moving block 5, a platform 6, a connecting shaft 7, a gear 8, a handwheel 9, a first magnet 10, a limiting rod 11, a limiting hole 12, a second magnet 13, a connecting bar 14, a round cover 15, a measuring instrument 16, a connecting ear 17, a connecting rod 18, a mounting bar 19, a spring 20 and a rack 21.

[0031] Embodiment 1: The existing measuring instrument 16 is installed on the positioning device by screws, and specific tools are required for both installation and disassembly, which is rather troublesome and time-consuming. Therefore, in this embodiment, the following technical solutions are adopted, such as Figure 1 , Figure 3 , Figure 4 and Figure 5 , since the limiting structure includes a platform 6, a measuring instrument 16, a connecting ear 17, a connecting rod 18, a mounting bar 19 and a spring 20, the connecting rod 18 is snap-fitted inside the hollow structure of the connecting ear 17, the lower end of the connecting rod 18 is snap-fitted inside the platform 6, the lower end of the mounting bar 19 is fixedly connected with springs 20 symmetrically on the left and right, and the connecting rod 18 is in a telescopic structure on the upper side of the platform 6 through the mounting bar 19. Therefore, the measuring instrument 16 is placed at the middle position on the upper end of the platform 6. After pulling the mounting bar 19 to make the connecting rod 18 snap-fitted inside the hollow structure of the connecting ear 17 and then snap-fitted inside the platform 6, the symmetrically arranged springs 20 drive the mounting bar 19 to descend, so that the lower end of the mounting bar 19 fits against the upper end of the connecting ear 17, and the position of the measuring instrument 16 on the platform 6 is limited through the connecting rod 18 and the mounting bar 19, thus it is easy to limit the position of the measuring instrument 16;

[0032] Embodiment 2: In the existing measurement, the process of manually adjusting the measuring tool pointer to "0" before measurement is slow and troublesome, with low efficiency. Therefore, in this embodiment, the following technical solutions are adopted, such as Figure 1 , Figure 2 and Figure 5, since the front end of the limiting rod 11 is snap-connected inside the limiting hole 12, the diameter of the circular ring structure formed by the first magnet 10 and the second magnet 13 is equal to the diameter of the guide rail 3, and the front and rear connecting bars 14 form a circular rod structure when they are fitted together. Therefore, the first magnets 10 are respectively placed on the left and right sides of the guide rail 3, and the front end of the first magnet 10 is snap-connected to the rear wall of the guide rail 3. The second magnet 13 is placed on the front side of the guide rail 3, and the limiting rod 11 is snap-connected inside the limiting hole 12, so that the rear end of the second magnet 13 is snap-connected to the front wall of the guide rail 3. Push the first magnet 10 outward so that the front and rear connecting bars 14 are fitted together and then nested inside the side wall of the support block 2. Rotate the round cover 15 to thread-connect it to the outer end of the connecting bar 14.

Therefore, when the position of the measuring instrument 16 needs to be moved, the handwheel 9 can be rotated to drive the connecting shaft 7 to rotate at the right end of the moving block 5. When the connecting shaft 7 rotates, it drives the gear 8 to rotate, so that the gear 8 meshes with the serrated structure at the upper end of the rack 21, and the gear 8 drives the moving block 5 to move left or right. The two guide sleeves 4 of the yarn slide left and right on the guide rail 3 at the corresponding positions, and the position of the platform 6 is stably adjusted, so as to facilitate the quick removal and return of the measuring tool, and reduce the ineffective labor caused by the repeated movement of the measuring tool.
