Abstract
The invention discloses a multi-angle limit rotary shaft which comprises a rotary shaft body and a base for mounting the rotary shaft body. A vertical rotary shaft socket for mounting the rotary shaft body and a limit part mounting socket parallel to a top plane of the base are arranged inside the base. A limit toothed block is arranged at the bottom of the rotary shaft body and is provided with a plurality of arc teeth on the periphery. A limit shaft with one end abutted between two adjacent arc teeth is arranged inside the limit part mounting socket, and a compression spring is arranged at the other end of the limit shaft. When the limit shaft of the rotary shaft is embedded between any two adjacent arc teeth at any angle, the rotary shaft body can be fixed by pressure applied to the limit shaft from the compress spring. When external force is applied to the rotary shaft body and is larger than the pressure applied to the rotary shaft body from the compression spring, the rotary shaft body can be pushed to rotate. Therefore, rotation and multi-angle optional positioning of the rotary shaft are achieved. The multi-angle limit rotary shaft is applied to the field of rotary shaft components.
