[0029] In detail, the telescopic rod of the longitudinal cylinder 2 is fixed to the workbench 6, the front cross-section of the guide rail 3 and the guide rail groove 7 is a T-shaped structure, and the guide rail 3 is slidably set with the workbench 6 through the guide rail groove 7. Combined with the fixation of the longitudinal cylinder 2 and the workbench 6, the longitudinal guiding stable sliding of the workbench 6 is ensured.

[0030] Furthermore, the guide rail 3 and the supporting guide balls 4 are two symmetrically arranged groups. The supporting guide balls 4 are twenty-five arranged longitudinally along the guide rail 3 and in rolling contact with the guide rail groove 7. The supporting guide balls 4 are made of a cemented carbide tungsten steel sphere structure as a whole, which has high strength, does not deform, and is durable.

[0031] Furthermore, the oil replenishing screw hole 61 , the oil storage inner cavity 31 , and the ball clamping groove 33 are integrally connected to ensure that the lubricating oil 32 is rolled and brushed on the guide rail groove 7 by the rolling supporting guide ball 4 .

[0032] In more detail, the oil-replenishing screw hole 61 is opened at the front end of the guide rail 3 , and the cap removal handle 5 is arranged at the front end of the oil-replenishing screw hole 61 , so as to facilitate the later replenishment of the lubricating oil 32 .

[0033] In general, the outer wall of the cap removal handle 5 is provided with finger pull grooves 8, and there are six finger pull grooves 8 arranged in a circle. A damping elastic layer 81 is provided on the inner groove wall of the finger pull groove 8.
