[0025] When the staff repairs the guide seat, the staff only needs to disassemble the first set 31 and the second set 32 and repair and replace according to the wear of the inner walls of the two, the interchangeability of the rod sleeve structure 3 is high, so that the staff does not need to replace the entire guide seat body 1, thereby reducing the maintenance cost of the guide seat.

[0026] The inner wall of the first guide hole 22 is provided with a plurality of matching structures, the matching structures are provided with curved portions 9, the bottom surface of the first set 31 is provided with a plurality of first curved grooves 10, and the bottom of the second set 32 is provided with second curved grooves 11. When the first set 31 and the second set 32 are matched and abutted, the cavity formed by the cooperation of the first curved grooves 10 and the second curved grooves 11 is attached to the curved portions 9, so as to guide the staff to install the first set 31 and the second set 32 in the first guide hole 22 at the correct position.

[0027] Embodiment two:

[0028] Reference Figure 3 、 Figure 4 Different from embodiment one, the matching structure includes a sliding column 12 and an elastic member 13, the inner wall of the first guide hole 22 is provided with a sliding hole 14 for sliding connection of the sliding column 12, the inner wall of the sliding hole 14 is provided with a positioning groove 15, the sliding column 12 is provided with a positioning member 16, the positioning member 16 is slidingly connected with the positioning groove 15, and the curved portion 9 is formed at the end of the sliding column 12 exposed from the sliding hole 14.
