[0021] As Figure 1 and 3 shown, the bottom of metal support body 1 is provided with lug installation groove 11, and lug 8 is arranged in cooperation in lug installation groove 11, the bottom of lug 8 is integrally provided with antiskid pad 2, and the top is bonded with double-sided adhesive tape 10, antiskid pad 2 is exposed outside lug installation groove 11, double-sided adhesive tape 10 is used for bonding with the groove bottom of lug installation groove 11, four magnet column insertion holes 12 are evenly arranged on the groove bottom of lug installation groove 11, and positioning magnet column 9 is inserted into magnet column insertion hole 12, the surface of lug 8 provided with double-sided adhesive tape 10 is fixed with a plurality of positioning magnet columns 9, all positioning magnet columns 9 pass through double-sided adhesive tape 10, and positioning magnet column 9 is used for realizing magnetic attraction of antiskid pad 2 and metal support body 1, antiskid pad 2 is detachable, which is convenient for replacement in the later period.
[0022] As Figure 1 shown, the bottom of antiskid ring 3 is bonded on the groove bottom in antiskid ring installation groove 7 by double-sided adhesive tape.
[0023] Antiskid ring 3 is made of hard plastic, antiskid nail 6 and antiskid ring 3 are integrated, the thickness of antiskid ring 3 is same with the depth of antiskid ring installation groove 7, so that protruding antiskid nail 6 is inserted into the wood at the bottom of desk and chair leg.
[0024] As Figure 1 shown, the counterbores 4 are hexagonal counterbores, the hexagonal handle pins are inserted into the counterbores 4, metal support body 1 can be rotated through the handle, and self tapping screw 5 can be rotated into the inside of desk and chair leg.
[0025] The metal support 1 is made of stainless steel, and the self-tapping screw 5 is connected to the metal support 1 by thread or welding.

When all the screws 5 are in, rotating the metal support body 1 pushes the anti-slip nail 6 on the anti-slip ring 3 into the wood of the table and chair leg, thereby increasing friction and preventing the metal support body 1 from rotating during use. The bottom anti-slip pad 2 is removable for quick replacement in case of damage. The anti-slip pad 2 is magnetically attracted to the metal support body 1 via four positioning magnets 9, preventing rotation and increasing connection strength. The anti-slip pad 2 is made of polytetrafluoroethylene (PTFE), which improves the wear resistance of the adjustable foot base, reduces the coefficient of friction between the adjustable foot base and the floor during movement, increases service life, reduces noise during movement, and is suitable for various scenarios including wooden floors, tiles, and carpets.
