Embodiment 2

[0023] On the basis of the first embodiment, in order to achieve the purpose of adjusting the size of the support surface, the adjustment component 4 includes a support plate 401 fixedly connected to the top of the lifting column 305, and the top edge of the support plate 401 is movably connected to three extension plates 402 through a hinge, and the bottom surfaces of the three extension plates 402 are hinged with a second connecting rod 403, and the bottom end of the second connecting rod 403 is hinged to the outer side of the second adjustment ring 404, and one side of the second adjustment ring 404 is threadedly connected to a second adjustment screw 405, and one end of the second adjustment screw 405 is inserted into the inside of the second jack 308; this structure can be adjusted by the first embodiment.

Embodiment 3

[0024] On the basis of the second embodiment, in order to achieve the purpose of adjusting the height of the support device according to actual conditions, the lifting assembly 3 includes a motor 301 fixedly connected to one side of the bottom surface of the support platform 1, the output end of the motor 301 is fixedly connected to the main gear 302, one side of the main gear 302 is meshed with a sub-gear 303, the middle of the top surface of the sub-gear 303 is fixedly connected to an adjustment column 304, the adjustment column 304 is threadedly connected to the middle adjustment groove of the lifting column 305, and the lifting column 305 is penetrated by two guide rods 306, and the two guide rods 306 are The top ends are fixedly connected to the limit block 307, and a plurality of second jacks 308 are provided on one side of the lifting column 305; the starting motor 301 drives the main gear 302 to rotate, and the rotation of the main gear 302 drives the adjusting column 304 to rotate through the sub-gear 303, and the adjusting column 304 drives the lifting column 305 to rise and fall when rotating, thereby driving the top support plate 401 to rise and fall, so as to achieve the purpose of adjusting the height of the support plate 401, so as to adjust the height of the support device according to the actual required height, thereby improving the adaptability of the support device.

[0025] In actual use, the main support column 202 and the auxiliary support column 205 at the bottom are used for support. At this time, the support bottom plates at the bottom ends of the two groups of support columns are in contact with the ground, increasing the contact area with the ground and making the support more stable. At the same time, the three groups of auxiliary support columns 205 distributed at equal angles are used to support the main support column 202. The principle of triangular stability is used to improve the stability of the support. Compared with the traditional single column structure, it is more stable. If the height of the support device needs to be adjusted, the motor 301 is started to drive the main gear 302 to rotate. When the main gear 302 rotates, it drives the auxiliary gear 303 to rotate, and the auxiliary gear 303 drives the adjustment column 303 04 rotates.
