In other embodiments, the sliding block 21 and the guide block 22 may be made of steel, copper, or other metals to increase the structural strength and the service life thereof, and the guide block 22 is slidably coupled to the guide groove 13. The slide block 21 is of a cylindrical structure, the diameter of the slide block 21 is smaller than that of the slide hole 12, and the slide block 21 and the slide hole 12 are coaxially arranged. An inner hole 23 is formed in the middle of the sliding block 21, and the inner hole 23 is of a circular hole structure. Six mounting holes 25 are formed in the sliding block 21, the six mounting holes 25 are divided into two groups of mounting hole groups, and the two groups of mounting hole groups are symmetrically arranged on two sides of the inner hole 23. The guide belt is adhered to the outer surface of the guide block 22, plays a role in guiding, and has the characteristics of extremely wear resistance, low friction, heat resistance, chemical corrosion resistance, vibration absorption performance and good dry-running characteristic. The guide block 22 has two side surfaces connected with the slide block 21 and a connecting surface connected with the two side surfaces, and a clearance groove 24 with an arc groove structure is arranged on the connecting surface.
