[0030] When in use, by selecting aluminum alloy as the material of the slide rail 2, on the one hand, aluminum alloy has the advantages of light weight, high strength and rigidity, and better durability; on the other hand, aluminum alloy will form a protective oxide layer on the surface, which can effectively prevent further corrosion, enable the slide rail 2 to maintain its original state, and improve the use effect; by providing a guide sleeve 5 on the sliding rod 4 and installing the guide sleeve 5 on the mounting hole 102, on the one hand, the sliding rod 4 can be prevented from being deflected, which helps to ensure the verticality of the sliding rod 4 and improve the accuracy of the test; on the other hand, direct friction between the sliding rod 4 and the lower plate 101 can be avoided, which causes wear of the sliding rod 4 and affects its service life.
