One side of the snap-fitting hole 18 is snap-fitted with the fixing member 15;

[0027] Specifically, the outer part of the sleeve 3 can be wrapped and protected by the reinforcing sleeve 1, so as to improve the strength of the sleeve 3 and reduce the deformation of the sleeve 3 caused by external forces during use. Through the threaded connection between the sleeve 3 and the extension pipe 4, the extended length of the extension pipe 4 can be adjusted. Furthermore, the use length of the entire heat shield can be adjusted, which is convenient for the heat shield to be applicable to steering gear main bodies 2 and first connecting rods 10 with different lengths. The extension pipe 4 can guide the installation of the limiting plate 11, which is convenient for the connection between the extension pipe 4 and the limiting plate 11.

[0030] The use process of a steering gear heat shield provided by the present utility model is as follows:

[0031] Working principle: First, the use length of the entire heat shield can be selected according to the length of the first connecting rod 10. Move the positioning plate 9 along the guiding strip 5, and the positioning plate 9 moves along the first connecting rod 10 until one side of the positioning plate 9 abuts against the steering gear body 2. Then, insert a bolt between the first limiting block 7 and the second limiting block 8 for fixation. At this time, the installation position of the sleeve 3 outside the first connecting rod 10 can be limited. Then, rotate the sleeve 3 to adjust the extending length of the sleeve 3 and change the covering position of the sleeve 3 on the first connecting rod 10. When the sleeve 3 reaches the specified position, engage one side of the fixing member 15 with the engaging hole 18 on the limiting plate 11, and then install bolts between the symmetrically arranged extension blocks 14 above and below to lock the two fixing members 15. Then, install a limiting bolt 16 between the fixing member 15 and the first connecting rod 10 to realize the connection between the fixing member 15 and the first connecting rod 10, completing the installation of the entire heat shield and also facilitating the disassembly and replacement of the heat shield in the future. The heat insulation layer 13 is made of fiberglass, with good heat insulation effect, and can reduce the interference of heat on the steering gear body 2 and the first connecting rod 10 during use.
