Abstract
The invention relates to a connector which comprises connector body. At least one connecting hole is formed in the connector body. At least two lock cylinders arranged around the circumferential direction of each connecting hole at intervals are arranged in each connecting hole. Arc radial protrusions which are coaxially arranged with the corresponding connecting holes are arranged on the inner walls of the lock cylinders. The diameter of the inner circle of each radial protrusion is smaller than the outer diameter of a corresponding hollow pipe. A first lock cylinder oblique plane and a second lock cylinder oblique plane are sequentially arranged on the peripheral face of each lock cylinder in the axial direction. A first pushing oblique plane adaptive to the first lock cylinder oblique plane in inclination is arranged on the wall of each connecting hole. The connector further comprises lock heads capable of moving in the axial directions of the connecting holes. The lock heads are provided with second pushing oblique planes which are used for being matched with the second lock cylinder oblique planes in a pushing mode when the lock heads move towards the connector body to enable the lock cylinders to close up in the radial direction so as to enable the radial protrusions to compress and deform the hollow pipes. The connector solves the problem that when an existing connector is connected with a hollow pipe, the hollow pipe needs to rotate, and the hollow pipe is not convenient to connect.
