[0004] In the above device, there are the following defects:

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1-Figure 4 As shown, an adjustable metal base includes a mounting plate 2 mounted above a base body 1 and a clamping block 3 mounted on the top of the mounting plate 2;

[0029] The bottom end of the mounting plate 2 is connected to a support rod 4, and a pulley 5 is installed at the bottom end of the support rod 4. The bottom end of the mounting plate 2 is installed with a first rotating shaft 6;

[0030] A through slot 7 is provided at the top of the base body 1, and a first slide slot 8 is provided at the top of the base body 1, a first slider 9 is slidably connected inside the first slide slot 8, two first screws 10 are rotatably connected to the inner wall of the base body 1, and the first screws 10 pass through the base body 1 and are connected to a first gear 11, a connection block 12 is threadedly connected to the surface of the first screw 10, and a second rotating shaft 13 is connected to the top of the connecting block 12, a connecting rod 14 is connected to the surface of the second rotating shaft 13, a rotating rod 15 is rotatably connected to one side of the base body 1, and a second gear 16 is connected to the surface of the rotating rod 15, a protective plate 17 is connected to one side of the base body 1, and the rotating rod 15 passes through the protective plate 17 and is connected to a toggle 18;

[0031] A mounting groove 19 is provided at the bottom end of the base body 1, and second slide grooves 20 are provided on both sides of the inner wall of the mounting groove 19, and a second slider 21 is slidably connected inside the second slide groove 20. A second screw rod 22 is rotatably connected to the surface of the base body 1, and a third gear 23 is connected to the surface of the second screw rod 22. A threaded tube 24 is threadedly connected to the surface of the second screw rod 22, and a suction cup 25 is installed at the bottom end of the threaded tube 24. The threads on both sides of the surface of the first screw rod 10 are opposite. When it rotates, the two connecting blocks 12 on the surface of the first screw rod 10 respectively move toward or away from the first slide groove 8 through the first slider 9.

[0032] Furthermore, the second slider 21 is connected to the surface of the threaded tube 24. The second slider 21 and the second slide groove 20 facilitate the threaded tube 24 to drive the suction cup 25 to move in a limited manner, so as to facilitate moving the suction cup 25 to the ground for adsorption. The position of the suction cup 25 can be adjusted according to the flatness of the ground.

[0033] Furthermore, the first slider 9 is connected to the bottom end of the connecting block 12, and the surfaces of the first gear 11 and the second gear 16 are meshingly connected. The first slider 9 and the first slide groove 8 facilitate the limited movement of the connecting block 12.

[0034] Furthermore, the connecting rod 14 is connected to the surface of the first rotating shaft 6, and the support rod 4, the pulley 5 and the inside of the through groove 7 are movably connected. When the connecting rod 14 moves, it can push the first rotating shaft 6 and the mounting plate 2 to which it is connected to move, thereby allowing the mounting plate 2 and the support rod 4 and the pulley 5 at its bottom to move. The support rod 4 and the pulley 5 can be moved to the inside of the base body 1 through the through groove 7, so that the pulley 5 is away from the ground to prevent it from moving.

[0035] Working principle: When the base body 1 needs to be placed, the base body 1 can be moved to the designated position by the pulley 5, etc., and the rotating rod 15 can drive the second gear 16 to rotate by rotating the knob 18. The rotation of the second gear 16 can drive the first gear 11 meshingly connected on its surface to drive the first screw 10 to rotate, so that the two connecting blocks 12 on the surface of the first screw 10 can move inside the first slide groove 8 through the first slider 9. The movement of the connecting block 12 can drive the connecting rod 14 and the mounting plate 2 connected thereto to move, so that The support rod 4 and the pulley 5 at the bottom end of the mounting plate 2 are moved to the inside of the base body 1 through the through groove 7, so that the pulley 5 does not contact the ground, thereby preventing the base body 1 from moving due to the pulley 5. After the pulley 5 is moved to the inside of the base body 1, the second screw rod 22 connected thereto can be rotated by rotating the third gear 23, so that the threaded tube 24 on the surface of the second screw rod 22 can be limitedly moved inside the second slide groove 20 through the second slider 21, and the suction cup 25 at the bottom end of the threaded tube 24 can be moved to the ground for adsorption, thereby improving the stability of the base body 1.
