[0009] As preferred, the side wall of the limiting block is fixedly installed with a first magnetic sheet, and the inner wall of the limiting groove is fixedly installed with a second magnetic sheet corresponding to the position of the first magnetic sheet. The first magnetic sheet and the second magnetic sheet are opposite in magnetism, so that the slider insert body can be more stably installed on the mounting portion.

[0010] As preferred, the upper surface of the slider insert body is provided with a counterbore corresponding to the position of the through hole. By providing the counterbore, the upper surface of the slider insert body remains flat after the screw is installed on the slider base, ensuring the stability of use.

[0011] As preferred, the side wall of the slider insert body is provided with a plurality of lubricating oil grooves. The lubricating oil grooves can improve the service life of the slider and reduce the maintenance frequency.

[0012] Compared with the prior art, the above technical scheme has the following technical effects:

[0013] The utility model discloses a threaded hole is set up on the slider base, and the corresponding through hole is set up on the slider insert body, and the slider insert body is directly locked on the slider base through the screw, cancels the pressing plate, increases the locking reliability of slider insert body, avoids the problem that the pressing plate produces the loosening of long -time use, sets up the magnetic sheet in the limiting block and the limiting groove, and slider insert body can be more stably installed on the slider base, sets up the lubricating oil groove on the side of slider insert body, improves the stability of slider insert body use.
