[0021] refer to Figure 1 , Figure 3 and Figure 4 The right side of the second bevel gear 11 and the top of the fourth bevel gear 18 are both fixedly connected with a turning handle 20.

[0022] As a technical optimization solution of the present invention, by setting the turning handle 20 , the operator can use the principle of a labor-saving lever to easily rotate the second bevel gear 11 and the fourth bevel gear 18 .

[0023] refer to Figure 1 , Figure 3 and Figure 4 A bearing is fixedly connected inside the driving box 13 , and the bearing is fixedly connected to the second threaded rod 14 .

[0024] As a technical optimization solution of the present invention, the friction between the drive box 13 and the second threaded rod 14 can be reduced by setting the bearing, thereby facilitating the rotation of the second threaded rod 14.

[0025] refer to Figure 1 Universal wheels 22 are fixedly connected around the bottom of the base plate 1.

[0026] As a technical optimization solution of the present invention, the provision of the universal wheel 22 can facilitate the operator to move the device, and the universal wheel 22 in the device has a self-locking function.

[0027] refer to Figure 1 Storage boxes 21 are fixedly connected to both sides of the top of the bottom plate 1.

[0028] As a technical optimization solution of the present invention, by providing a storage box 21, the space above the bottom plate 1 can be utilized, and the storage box 21 can store tools and materials.

[0029] refer to Figure 1 The top of the workbench 4 and the top of the movable plate 16 are both provided with anti-slip grooves.

[0031] The working principle and use process of the utility model: when the operator needs to unfold the movable plate 16, the operator rotates the handle 20 to drive the fourth bevel gear 18 to rotate, and then drives the third bevel gear 17 to rotate, thereby driving the second threaded rod 14 to rotate, so that the movable block 15 and the movable plate 16 move forward until the front end of the movable plate 16 is in contact with the wall, and then the operator can work on the top of the movable plate 16;

[0032] When the operator needs to adjust the height of the workbench 4 and the movable plate 16, the operator rotates the handle 20 to drive the first gear 12 to rotate. The two first gears 12 rotate synchronously under the action of the synchronous belt. The rotation of the first gear 12 drives the second bevel gear 11 to rotate, thereby driving the first bevel gear 9 to rotate, and then driving the sleeve 8 to rotate. Since the sleeve 8 is threadedly connected to the first threaded rod 10, and the first threaded rod 10 is fixedly connected to the support frame 3, the first threaded rod 10 cannot rotate. Therefore, when the sleeve 8 rotates, the first threaded rod 10 moves up or down, thereby driving the support frame 3, the workbench 4 and the movable plate 16 to move up or down.
