An upper positioning block 22 is installed on the upper side of the tie rod main body 1. An insertion rod 23 is integrally formed on the bottom surface of the upper positioning block 22. A screw rod 24 is movably installed on the side wall of the lower positioning block 21 through a thread. A support rod 25 is fixedly connected inside the lower positioning block 21 and the upper positioning block 22. A sponge sleeve 26 is sleeved outside the support rod 25. By installing the protection structure 2 on the tie rod main body 1, the protection structure 2 can cover the outer side of the middle part of the tie rod main body 1. Cooperating with the sponge sleeve 26 can prevent flying sand and gravel from directly hitting the tie rod main body 1, ensure the service life of the tie rod main body 1, and play a certain noise reduction effect, improving the practicability of the device;

[0025] A shielding structure 3 is installed on the protection structure 2. The shielding structure 3 includes an internal thread ring 31 which is fixedly installed on the side wall of the upper positioning block 22. Two external thread shells 32 are movably installed inside the internal thread ring 31 through threads. Through grooves 33 are formed on the surfaces of the external thread shells 32, and barbs 34 are adhered to the inner walls of the through grooves 33. When the two external thread shells 32 are spliced together, they can form a circular ring. When the two external thread shells 32 are screwed into the inside of the internal thread ring 31, the external thread shells 32 can shield and protect the rotating wheel 11 on the outside. Cooperating with the barbs 34, it can prevent sand and gravel from entering the connection between the rotating wheel 11 and the pull rod main body 1, making the rotation of the rotating wheel 11 smooth and stable, avoiding jamming, and ensuring the use experience of the device.

[0026] Furthermore, the lower positioning block 21 and the upper positioning block 22 cooperate with each other. The insertion rod 23 is inserted into the lower positioning block 21, and the screw rod 24 penetrates through the insertion rod 23.

Both the lower positioning block 21 and the upper positioning block 22 are attached to the outer wall of the pull rod main body 1. By rotating the screw rod 24, the screw rod 24 can be screwed into the lower positioning block 21. The screw rod 24 penetrates through the insertion rod 23, so that the lower positioning block 21 and the upper positioning block 22 can be tightly connected and firmly fixed on the outside of the pull rod main body 1. Then, the sponge sleeve 26 is sleeved on the outer side of the support rod 25 on the lower positioning block 21 and the upper positioning block 22. The support rod 25 can support and fix the sponge sleeve 26 on the inner side, so that the position of the sponge sleeve 26 can be fixed. The sponge sleeve 26 is sleeved on the outer side of the middle part of the pull rod main body 1, which can shield and protect the middle part of the pull rod main body 1, prevent the pull rod main body 1 from being knocked and worn by sand and gravel, ensure the service life of the pull rod main body 1, and prevent sand and gravel from hitting the pull rod main body 1, avoiding the generation of noise, achieving a certain noise reduction effect, and improving the practicability of the device;

[0030] When two groups of external thread shells 32 are spliced together, they can form a circular ring. When the two groups of external thread shells 32 are screwed into the inner side of the internal thread ring 31, the external thread shells 32 can shield and protect the rotating wheel 11 on the outside. Cooperating with the hair needles 34, it can prevent sand and gravel from entering the connection between the rotating wheel 11 and the pull rod main body 1, make the rotation of the rotating wheel 11 smooth and stable, avoid stalling, and ensure the use experience of the device.
