The wheels 5 are used in conjunction with each other, and the side of the push plate 6 away from the limit pin 7 is fixedly connected with a first spring 8, and the end of the first spring 8 away from the push plate 6 is fixedly connected to the inner wall of the U-shaped groove 3, and a push rod 9 is fixedly connected between the bottoms of the two push plates 6, and the push rod 9 is slidably connected to the U-shaped groove 3. One end of the push rod 9 extends to the outside of the wire storage box 1. In the above device, the two limit pins 7 can be used to limit the rotation direction of the ratchet 5. When the push plate 6 is driven by the push rod 9 through the first spring 8, the push plate 6 is driven to reset, and when the winding shaft 4 rotates, the ratchet 5 is driven to rotate.

[0033] Among them, two baffles 10 are fixedly connected to the outside of the winding shaft 4 and located inside the wire box 1. One end of the winding shaft 4 away from the ratchet 5 extends to the outside of the wire box 1 and is fixedly connected to a rotating disk 11. The two baffles 10 in the above device are used to limit the measuring rope. By rotating the rotating disk 11, the winding shaft 4 can be driven to rotate.

[0034] Among them, a limiting groove 13 is opened at the bottom of the inner wall of the U-shaped groove 3, and a second spring 14 is fixedly connected inside the limiting groove 13. A limiting ball 15 is arranged on the top of the second spring 14. Two limiting holes 16 are opened at the bottom of the push rod 9. The limiting ball 15 is used in conjunction with the limiting hole 16. In the above device, when the push rod 9 is pulled or pushed, the second spring 14 will be compressed by the limiting ball 15, so that the limiting ball 15 cooperates with any limiting hole 16, so that the lateral trajectory of the push rod 9 is limited.

[0035] The bottom of the wire box 1 is fixedly connected with a sleeve 17, and the interior of the sleeve 17 is slidably connected with a support rod 18. In the above device, the sleeve 17 slides outside the support rod 18, so that the height of the wire box 1 can be adjusted.

[0036] Among them, the outer side of the sleeve 17 is threadedly connected with a screw 20, and one side of the support rod 18 is equidistantly provided with a thread groove 19, and the screw 20 is used in conjunction with the thread groove 19. In the above device, the screw 20 is threadedly connected to any thread groove 19, so that the height of the wire storage box 1 can be limited.

[0037] The bottom of the support rod 18 extends to the bottom of the sleeve 17 and is fixedly connected to a base 21 . In the above device, the base 21 is in contact with the ground, so that the wire box 1 can be stabilized.

[0039] Working principle:

[0040] like Figure 1-Figure 6 As shown, in the above device, the measuring line is firstly wound around the outside of the winding shaft 4, and the measuring line is limited by two baffles 10. When it is necessary to pay out the line, the push rod 9 is pushed so that one of the limit pins 7 is stuck inside the teeth of the ratchet 5, so that the winding shaft 4 can only rotate in one direction. When the line is paid out to the required position, the push rod 9 is pulled so that the other limit pin 7 is stuck inside the ratchet 5. At this time, the winding shaft 4 is in the winding state, and the measuring line can be tightened, which can better ensure the straightening of the line, thereby improving the accuracy and precision of the measurement, and then the tightness of the line can be adjusted quickly and easily, improving the efficiency and repeatability of the measurement, and greatly improving the operation quality and use efficiency compared with the traditional device.

[0041] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
