Document Type and Number:
WIPO Patent Application WO/2021/233205
Kind Code:
A1
Abstract:
A height adjusting mechanism (100), comprising a base (10), a first rotating member (20), a sliding member (30), a second rotating member (40), and a gear (50). The first rotating member (20) is rotatably arranged on the base (10); a helical part (20a) is formed on the outer surface of the first rotating member (20), a transmission part (30a) matching the helical part (20a) is formed on the sliding member (30), the second rotating member (40) is located on a lateral side of the sliding member (30), a first tooth part (40a) meshing with the gear (50) is formed in the rotating circumferential direction of the second rotating member (40), the gear (50) and the first rotating member (20) are connected and arranged coaxially, the second rotating member (40) rotates to drive the gear (50) to rotate, and the gear (50) drives the first rotating member (20) to rotate, so that the sliding member (30) reciprocates linearly along the height direction of the base (10).
