[0032] The reinforcement assembly 6 comprises:

[0033] A threaded collar 61, wherein two threaded collars 61 are provided and symmetrically sleeved on both sides of the rod body 1, and a reinforcing sleeve 62 is integrally provided on the side end of the threaded collar 61 away from the rod body 1, and the inner diameter of the reinforcing sleeve 62 contacts the outer surface of the movable rod 3;

[0034] Threaded segments 63 , threaded segments 63 are provided on both sides of the rod body 1 , and the threaded collar 61 is spirally connected to the threaded segments 63 .

[0035] In the present embodiment, in order to improve the structural strength of the connection between the rod body 1 and the movable rod 3, a reinforcement component 6 is provided, and the reinforcement component 6 is used to perform reinforcement after the length of the suspension rod is adjusted. Specifically, the threaded collar 61 is rotated to move the threaded collars 61 on both sides closer together until the side of the reinforcement sleeve 62 is pressed against the side end of the rod body 1. At this time, the reinforcement component 6 is adjusted, the inner side of the reinforcement sleeve 62 is pressed against the outer wall of the movable rod 3, and at the same time, the side is pressed against the side end of the rod body 1, and the inside of the threaded collar 61 is connected to the outer surface of the rod body 1, thereby realizing structural reinforcement of the connection between the rod body 1 and the movable rod 3. Moreover, the threaded collar 61 can be freely disassembled as needed, so as to facilitate the maintenance and replacement of the parts of the suspension rod.

[0036] The clamping assembly 5 comprises:

[0037] A clamping groove 51, wherein two clamping grooves 51 are provided and symmetrically arranged on two side walls of the adjusting groove 2;

[0038] A clamping block 52, wherein each of the clamping slots 51 is slidably mounted with a clamping block 52;

[0039] Grooves 53, two groups of grooves 53 are equidistantly distributed on the outer side wall of the movable rod 3;

[0040] A protrusion 54 is arranged in the middle of the clamping block 52, a mounting groove 55 is opened in the middle of the clamping groove 51, the protrusion 54 is slidably connected in the mounting groove 55, and a spring 56 is connected between the protrusion 54 and the bottom wall of the mounting groove 55; the side of the clamping block 52 facing away from the threaded ring 61 is arranged as an arc surface 57, and the side facing the threaded ring 61 is arranged as a vertical surface.

Due to the structure of the arc block 58 The arrangement makes the threaded collar 61 gradually press down and cover the arc block 58, so that the clamping block 52 moves down again and enters the groove 53 to complete the length adjustment action; the vertical surface arranged at the bottom of the clamping block 52 can cooperate with the vertical surface of the groove 53, thereby forming a limiting effect to ensure that the two are firmly connected; the arrangement of the spring 56 can allow the clamping block 52 to automatically move up after being released from the pressure of the threaded collar 61, thereby realizing the disassembly between the movable rod 3 and the rod body 1 and facilitating the execution of the length adjustment action; at the same time, the pre-recovery elastic force of the spring 56 after compression will prompt the clamping block 52 and the top arc block 58 to always press against the inner side of the threaded collar 61, thereby achieving the effect of improving the connection strength.

[0043] The outer wall of the threaded collar 61 is configured to be a hexagonal shape 59. The hexagonal shape 59 structure enables the threaded collar 61 to be rotated using a hexagonal wrench or an adjustable wrench.
