Meanwhile, a spring 64 is sleeved on the rotating rod 62, and the spring 64 is positioned between the fixing nut 63 and the rotating rod 61. After the position adjustment of the supporting rod 5 is completed, the user rotates the fixing nut 63, the fixing nut 63 approaches the rotating rod 61 at this time, then the spring 64 is compressed, the compression of the spring 64 can increase the pressure between the fixing nut 63 and the rotating rod 61, the rotating rod 62 and the rotating rod 61 can be fixed, and the possibility that the fixing nut 63 is loosened is reduced.

Referring to fig. 3 and 5, a screw hole 72 is formed in a side wall of the sliding sleeve 7, the screw hole 72 penetrates through the side wall of the sliding sleeve 7, and a screw 73 is connected to the screw hole 72 through a thread. After the position control of bracing piece 5 was accomplished, the user rotated screw rod 73, made screw rod 73 rotate in screw 72, then made screw rod 73 be close to connecting axle 2, increased the pressure between screw rod 73 and the connecting axle 2, and then increased frictional force, reduced sliding sleeve 7 and taken place gliding possibility, further improved the stability of connecting, guaranteed that the atress is stable.

The implementation principle of the embodiment 3 is as follows: the user rotates the rotating rod 61 and the rotating rod 62, and then adjusts the distance between the main shaft 3 and the auxiliary shaft 4, then the user connects the ball pin 221 with the vehicle frame, rotates the main rotating shaft 33 and the auxiliary rotating shaft 42, then connects the connecting seat 1 with the vehicle axle, then the user rotates the fixing nut 63, makes the position of the rotating rod 61 and the rotating rod 62 fixed, then screws up the screw rod 73, makes the position of the sliding sleeve 7 fixed.

Example 4

Referring to fig. 4 and 6, the present embodiment is different from embodiment 3 in that the supporting rod 5 is different in a telescopic manner, a sliding groove 611 is coaxially formed at one end of the rotating rod 61 away from the transition rod 71, and the sliding groove 611 is formed along an axial direction of the rotating rod 61. The end of the rotating lever 62 remote from the transition lever 71 is slidably coupled in the slide groove 611. The user can slide in the sliding groove 611 by pulling the rotating lever 62, thereby conveniently adjusting the total length of the supporting bar 5.

Referring to fig. 4 and 6, the rotating rod 61 is provided with a plurality of limiting holes 612, the limiting holes 612 are uniformly formed along the length direction of the rotating rod 61, and the limiting holes 612 penetrate through the side wall of the rotating rod 61 and communicate with the sliding groove 611. The rotating rod 62 is provided with a fixing groove, and a limiting rod 65 is connected to the fixing groove in a sliding mode. The limiting rod 65 comprises a main body 651 and a limiting spring 652, the main body 651 is slidably connected in the fixing groove, the limiting spring 652 is fixedly connected in the fixing groove, one end of the limiting spring 652 is fixedly connected with one end of the main body 651, and the other end of the limiting spring 652 is fixedly connected with the bottom surface of the fixing groove. When adjusting the length of the support rod 5, the user presses the main body 651, so that the main body 651 compresses the limit spring 652, then the main body 651 contracts into the fixing groove, then the rotating rod 62 is pulled, so that the fixing groove is aligned with the corresponding limit hole 612, then the limit spring 652 gradually recovers to a natural state, so that the main body 651 is inserted into the limit hole 612, and therefore the stability of the rotating rod 61 and the rotating rod 62 is guaranteed.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
