[0021] Specifically, the connection relationship between the first bevel gear 102 and the second bevel gear 103 is a meshing connection.
[0022] In the present embodiment, by setting the first bevel gear 102 and the second bevel gear 103, utilizing the meshing connection relationship between the first bevel gear 102 and the second bevel gear 103, the second bevel gear 103 is driven to rotate by rotating the rotating rod 104, so that the second bevel gear 103 drives the first bevel gear 102 to rotate, and then the first bevel gear 102 drives the threaded rod 101 to rotate, thereby achieving the purpose of driving the threaded rod 101 to rotate.
