Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in figures 1, 2, 3, 4 and 5, the ratchet type full circle chamfering device comprises a full circle chamfering device body 1, the full circle chamfering device body 1 is composed of a rotating handle 2 and a chamfering mechanism 3, a fixing part 4 is arranged between the rotating handle 2 and the chamfering mechanism 3, a screw hole 5 with screw threads is arranged at the central part of the fixing part 4, the top end part of the chamfering mechanism 3 extends into the screw hole 5 and is in threaded connection with the screw hole 5, the fixing part 4 is connected with the rotating handle 2 through a connecting part 6, the longitudinal section of the connecting part 6 is in a T shape, the top end part of the connecting part 6 is provided with a plurality of barbs 7 which are distributed circumferentially, a plurality of matching parts 8 which extend into the rotating handle 2 and are matched and connected with the inside of the rotating handle 2 are distributed axially at the lower end part of the connecting part 6, a hollow groove 9 which is communicated with the screw hole 5 and is used for embedding the top end of, the outer peripheral wall of the top end of the connecting part 6 is attached to the inner peripheral wall of the empty groove 9, a plurality of barbs 7 at the top end of the connecting part 6 are abutted against the bottom wall of the empty groove 9, a slot 10 extending towards the inside of the fixing part 4 is obliquely arranged on the bottom wall of the empty groove 9, a spring 11 and a strip-shaped steel ball 12 are arranged in the slot 10, one end of the spring 11 is abutted against the bottom wall of the slot 10, the other end of the spring 11 is abutted against the bottom of the strip-shaped steel ball 12, the top of the strip-shaped steel ball 12 extends out of the slot 10 and is matched with the barbs 7, the full circle chamfering device body 1 extends into the pipe fitting, the rotating handle 2 is rotated, the connecting part 6 rotates along with the rotation of the rotating handle 2 in the same direction, so as to drive a plurality of barbs 7 in the connecting part 6 to rotate circumferentially, wherein each barb 7 can sequentially contact with the strip-shaped steel ball 12, simultaneously because the top of connecting portion 6 imbeds in mounting 4, and the periphery wall of this connecting portion 6 laminates with the interior wall of mounting 4 mutually, consequently connecting portion 6 rotates and drives mounting 4 and be rotary motion with 4 screw-thread fit's of mounting chamfering mechanism 3, carries out the chamfer to the pipe fitting promptly, the chamfer finish the back, only need extract whole circle chamfer ware body 1 can, this ratchet formula whole circle chamfer ware can realize carrying out the chamfer to the pipe fitting of different footpath mouths.
