DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0021] See also Figures 1 to 6 A lifting mechanism includes a first bracket 100 and a second bracket 200, wherein the second bracket 200 is mounted on the first bracket 100 and can be lifted and lowered along the first bracket 100. The first bracket 100 includes two first support plates 110, and the second bracket 200 includes two second support plates 210. The two first support plates 110 are parallel to each other, and the two second support plates 210 are parallel to each other and connected by a third support plate 220. The two second support plates 210 are located between the two first support plates 110, and the first support plates 110 and the second support plates 210 are parallel to each other.

[0022] A support rod 300 is installed on one side of the first support plate 110 facing the second support plate 210, and a guide groove 400 is installed on one side of the second support plate 210 facing the first support plate 110. The support rod 300 is partially embedded in the guide groove 400. When the second bracket 200 moves along the first bracket 100, a relative movement occurs between the support rod 300 and the guide groove 400. The guide groove 400 includes a first surface 410 and a second surface 420. The first surface 410 is the bottom surface of the guide groove 400, and the second surface 420 is the side surface of the guide groove 400, and the two are perpendicular to each other. A first mounting cavity 310 and a second mounting cavity 320 are provided on the support rod 300, the opening of the first mounting cavity 310 faces the first surface 410, and the opening of the second mounting cavity 320 faces the second surface 420. At the same time, a rotatable first roller 311 is installed in the first mounting cavity 310, and the first roller 311 contacts the first surface 410. A rotatable second roller 321 is installed in the second mounting cavity 320, and the second roller 321 contacts the second surface 420, so that the support rod 300 contacts the guide groove 400 in two directions. When the second bracket 200 is raised or lowered, the first roller 311 and the second roller can limit the horizontal movement of the second bracket 200, thereby ensuring the stability of the movement of the second bracket 200.

[0023] A support member 500 is also installed between the two first support plates 110. The support member 500 is a plate-like structure. A mounting groove is opened at the center of the support member 500. A third roller 510 is installed in the mounting groove. The third roller 510 contacts the second support plate 210, thereby further limiting the movement of the second bracket 200, thereby further ensuring the stability of the lifting and lowering of the second bracket 200.
