[0021] The conical section 22 of the utility model can facilitate the fixing device 3 to be inserted from the bottom end of the shift lever 2 and moved to the position where reinforcement is desired.

[0022] The basic usage of this utility model is:

[0023] When installing

[0024] S1: insert the fixing device 3 from one side of the bottom end of the shift lever 2 and put it on the shift lever 2;

[0025] S2: Fix the bottom end of the shift lever 2 on the gearbox;

[0026] S3: Put the shift ball head 1 on the shift lever 2;

[0027] S4: Move the fixing device 3 to the position of the neck section 11 a, and thread the ring body 31 onto the neck section 11 a. At this time, the bayonet is clamped onto the conical section 22, and finally the shift ball head 1 is fixed onto the shift lever 2.

[0028] To disassemble, just follow the installation steps in reverse order.

[0029] In order to ensure that the shift rod 2 will not move after being inserted into the shift ball head 1 during installation, and to facilitate the subsequent installation of the fixing device 3, the shift ball head includes a shell 11 and a solid part 12. The solid part 12 is fixed at the lower end of the shell 11. A threaded blind hole 121 is provided below the solid part 12. After the shift ball head 1 is put on the shift rod 2, the top of the shift rod 2 can be inserted into the threaded blind hole 121 and threadedly connected with the threaded blind hole 121. In this way, the shift ball head 1 and the shift rod 2 are pre-fixed, and the shift ball head 1 will not move circumferentially and axially on the shift rod 2. Workers do not need to spare a hand to hold the shift ball head 1, which facilitates installation. After the position of the shift ball head 1 is pre-fixed, when the fixing device 3 is fixed on the neck section 11a, the bayonet of its latching teeth 32 is just located at the bottom of the tapered section 22 of the shift rod, and can clamp the tapered section 22. In this way, the shift lever 2 actually has two fixed positions with the shift ball head 1, and the connection is more secure.

[0030] The utility model also includes a bottom support part 4, which is a cylinder, and the channel inside it is conical, which matches the shape of the conical section 22. The bottom support part 4 can be sleeved outside the conical section 22 and fixed to the conical section 22. The fixing device 3 also includes two support parts 33, which are symmetrically fixed on both sides of the ring body 31, and the bottom ends of the support parts 33 can contact the top end surface of the bottom support part 4. The cooperation between the support parts 33 and the bottom support part 4 can prevent the ring body 31 from falling downward after being disconnected from the threaded connection with the neck section 11a due to the bumps and vibrations of the vehicle.

[0031] Specifically, the fixing method of the bottom bracket 4 and the tapered section 22 is as follows: a connecting hole is provided on the circumferential surface of the tapered section 22, and a fixing hole is provided on the circumferential surface of the bottom bracket 4. The connecting hole and the fixing hole are fixed by the same bolt, and the vicinity of the fixing hole of the bottom bracket 4 is a platform surface, and the bolt head and nut are attached to the platform surface. During the installation process, after the fixing device 3 is put on the shift lever 2, the bottom bracket 4 is then put on.

[0032] In order to prevent the ring body 31 from being positioned upward when manually threadedly fixed with the neck section 11a, so that the latching teeth 32 clamp too little of the shift lever 2, the neck section 11a is provided with an upper limit portion 11b. The upper limit portion 11b is conical, and the diameter of the upper limit gradually increases from the bottom to the top. The upper limit portion 11b limits the ring body 31 upward.

[0033] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
