Locking device with spring bolt

The invention discloses a locking device with a spring bolt, which comprises a lock body and the spring bolt, a bolt is connected with the lock body to form a fixed relationship between the bolt and the lock body, the spring bolt is arranged between the lock body and the bolt, the spring bolt comprises a hexagonal structure at the end part, the lock body is provided with a spring piece, and the spring piece is rotated to lock the lock body. The spring piece and the hexagonal structure at the end of the spring bolt generate relative movement, the hexagonal structure at the end of the spring bolt extrudes the spring piece and the spring bolt to be in a rotating state, or the spring piece is reset, the spring piece is connected with any outer edge of the hexagonal structure at the end of the spring bolt in a clamping mode, rotation of the spring bolt is limited, and the spring bolt is in a locking state. According to the invention, rapid separation and locking of the two parts are realized, repeated application
