[0035] The following will be combined with the drawings in the specification of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] Reference Figure 1 , Figure 2 and Figure 5 The utility model provides an embodiment: a pull rod assembly structure, including a front pull rod 1 and a rear pull rod 2, the front pull rod 1 is located in the middle of the rear pull rod 2, the far sides of the front pull rod 1 and the rear pull rod 2 are fixedly connected with a connecting head 3, the middle part of the front pull rod 1 is fixedly connected with a front clamping ring 8, the outer side of the front clamping ring 8 is rotatably connected with a front pressure ring 9, the rear side of the front pressure ring 9 is fixedly connected with a rubber sleeve 10, the rear side of the rubber sleeve 10 is fixedly connected with a rear pressure ring 11, the inside of the rear pressure ring 11 is rotatably connected with a rear clamping ring 12, the middle part of the rear clamping ring 12 is fixedly connected with a connecting ring 13, and the connecting ring 13 is located in the middle of the outer wall of the rear pull rod 2, and an adjusting component is arranged between the front pull rod 1 and the rear pull rod 2.

[0037] The front side of the rubber sleeve 10 can be fixed to the front pull rod 1 by the front clamping ring 8 and the front pressure ring 9, and the rubber sleeve 10 can be fixed to the outside of the rear pull rod 2 by the rear clamping ring 12 and the rear pressure ring 11. Therefore, the rubber sleeve 10 can be set on the outside of the connection between the front pull rod 1 and the rear pull rod 2. At this time, the rubber sleeve 10 can be used to protect the connection between the front pull rod 1 and the rear pull rod 2, so as to prevent dust and other debris from entering between the two and affecting them, which is beneficial to ensure the normal operation of the device.

[0038] Reference Figure 3 and Figure 6The middle part of the connecting ring 13 is threadedly connected with a fixing ring 14, and the inner wall of the fixing ring 14 contacts the outer wall of the rear tie rod 2. The front side of the fixing ring 14 is provided with a plurality of openings 15, and the openings 15 are set in a wedge shape, and the fixing ring 14 is set in an elastic material. The wall thickness of the fixing ring 14 is set in a wedge shape with a thick rear side and a thin front side.

[0039] By rotating the connecting ring 13 to make it close to the first anti-sliding block 16, the connecting ring 13 can be used to squeeze the fixing ring 14 so that it presses the rear rod 2, thereby fixing the rubber sleeve 10. When the connecting ring 13 is separated from the fixing ring 14, the pressing of the fixing ring 14 on the rear rod 2 can be cancelled. At this time, the fixing ring 14 can be pulled to move outside the rear rod 2, thereby avoiding the phenomenon that the rubber sleeve 10 is too short.

[0040] Reference Figure 1 , Figure 3 and Figure 5 A first anti-sliding block 16 is fixedly connected to the rear side of the outer wall of the fixing ring 14 , and a second anti-sliding block 17 is fixedly connected to the outer wall of the connecting ring 13 .

[0041] The first anti-sliding block 16 can facilitate the movement of the fixing ring 14 , and the second anti-sliding block 17 can facilitate the rotation of the connecting ring 13 .

[0042] Reference Figure 2 and Figure 4 The front side of the rear tie rod 2 is threadedly connected with a bolt 4, one side of the bolt 4 is threadedly connected with a nut 5, and the bolt 4 passes through the front tie rod 1. A plurality of through holes 7 are provided in the middle of the front tie rod 1, and the bolt 4 is located inside one of the through holes 7. A slide groove 6 is provided inside the front side of the rear tie rod 2, and the rear side of the front tie rod 1 is located inside the slide groove 6.

[0043] By removing the bolts 4 and nuts 5, the front pull rod 1 can be pulled to slide inside the rear pull rod 2. At this time, the total length of the device can be adjusted, thereby improving the applicability of the device.

[0044] Working principle: When in use, when the total length of the device needs to be adjusted, first rotate the connecting ring 13 to make it away from the first anti-sliding block 16. At this time, the connecting ring 13 can be separated from the fixing ring 14. At this time, the connecting ring 13 can be moved to the outside of the front pull rod 1, and then the bolt 4 and the nut 5 can be removed. At this time, the position of the front pull rod 1 inside the rear pull rod 2 can be adjusted, so as to achieve the purpose of adjusting the total length of the device. After the adjustment is completed, reinstall the bolt 4 and the nut 5, and make the bolt 4 and the nut 5 pass through the front pull rod 1 and the rear pull rod 2, and make it pass through the through hole 7. At this time, by tightening the bolts 4 and the nuts 5, the front pull rod 1 and the rear pull rod 2 can be fixed, thereby completing the operation of adjusting the length of the device. Finally, by pulling the connecting ring 13 close to the fixing ring 14, the connecting ring 13 is then tightened on the fixing ring 14. At this time, the rubber sleeve 10 can be fixed on the outside of the connection between the front pull rod 1 and the rear pull rod 2, and after the connecting ring 13 is separated from the fixing ring 14, the clamping of the fixing ring 14 on the rear pull rod 2 can be cancelled. At this time, the fixing ring 14 can be pulled to move it on the outside of the rear pull rod 2, thereby avoiding the phenomenon that the rubber sleeve 10 is too short.
