A main slot for inserting the movable support components is provided on one side of the support base 26, and a detachable limiting member 28 is inserted into the main slot on one side of the support base 26. A clearance hole is provided in the movable seat 23 at the support component location, which provides clearance space for the support base 26 and the movable support components. The limiting member 28 is provided to prevent the movable support components inserted into the support base 26 from falling out.

[0025] The movable support assembly includes a movable support plate 27, with a V-shaped groove at the top and a T-shaped fixing block installed at the bottom. A magnet 273 is installed on one side of the T-shaped fixing block. A magnetic groove for inserting the magnet 273 is provided inside the support base 26, and the inner wall of the magnetic groove is provided with a magnetic layer with the opposite polarity to that of the magnet 273.
