[0020] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1-Figure 3 As shown, the embodiment of the utility model provides a high-efficiency and wear-resistant vehicle spline shaft seat fork, comprising:

[0022] A connecting tube 1, a fixing groove is provided at the bottom of the connecting tube 1, and a thread is provided in the fixing groove to facilitate the installation of the device. A base 2 is provided at the top of the connecting tube 1, and two positioning forks 6 are provided on the base 2. The two positioning forks 6 are penetrated with mounting holes, and the two positioning forks 6 are arranged opposite to each other;

[0023] The fixing assembly includes a mounting block 5 fixedly arranged on the top of the base 2, a mounting groove 9 is arranged at the bottom of the mounting block 5, a connecting block 7 is fixedly arranged on the inner side of the bottom end of the two positioning forks 6, the two connecting blocks 7 are both extended into the mounting groove 9 for matching, and the outer ends of the two connecting blocks 7 are both provided with a connecting groove 8, and the two connecting grooves 8 are arranged to abut against each other. The two connecting blocks 7 are as shown Figure 2 As shown, the two connection grooves 8 are arranged in an inverted manner, so that the two connection grooves 8 are arranged opposite to each other, so that the two connection blocks 7 can be closely fitted to each other;

[0024] The mounting block 5 is provided with a through hole 11, in which a bolt 12 is movably provided, and the bolt 12 is fixedly connected to the connecting tube 1.
