Detailed Description

The utility model will be further described with reference to the drawings and specific examples to aid in understanding the context of the utility model. The method used in the utility model is a conventional method unless specified otherwise; the raw materials and devices used, unless otherwise specified, are all conventional commercial products.

The utility model provides a telescopic and detachable ball-socket chamfering compound cutter, which is shown in fig. 1-3 and comprises a cutter body 1 and a ball-socket cutter 2. The cutter body 1 is provided with an additional cutter component 3 in a telescopic manner, the cutters in the additional cutter component 3 can extend out of the circumferential surface of the cutter body 1 and can also shrink into the cutter body 1, and the cutter body further comprises a fixing device 6 for fixing the cutters in the additional cutter component 3 in a shrinking state.

The additional knife component 3 comprises a containing hole 4 arranged on the end face of the knife body 1 far away from the ball socket knife 2, a spring knife component 5 is telescopically arranged in the containing hole 4, a knife outlet hole 402 is arranged on the inner wall of the front end of the containing hole 4 and penetrates through the circumferential surface of the knife body 1, and the additional knife component is used for containing an additional knife 504 to extend out of the circumferential surface of the knife body 1. The spring knife assembly 5 moves telescopically in the accommodating hole 4, so that the additional knife assembly 3 has two states of an extending knife and a retracting knife.

The spring knife assembly 5 comprises an elastic support 501, one end of the elastic support 501 is bent and then connected with a bearing platform plate 502, and the other end of the elastic support 501 is provided with an operation rod 503 perpendicular to the central shaft of the knife body 1. The inner side surface of the bearing platform plate 502 is connected with the elastic support 501 through a spring, an additional knife 504 is detachably arranged on the outer side surface of the bearing platform plate 502, the additional knife 504 corresponds to the knife outlet hole 402, and the additional knife 504 is a chamfering knife. After the outer side of the bending part of the elastic support 501 is extruded, the bearing plate 502 moves towards the direction of the elastic support 501, and then the additional knife 504 on the bearing plate 502 is driven to move towards the elastic support 501, so that the function of shrinking the additional knife 504 into the knife body 1 is achieved. When the bending part of the elastic support 501 is not extruded any more, the additional knife 504 ejects the accommodating hole 4 to be positioned at the outer side of the knife body 1 under the action of the spring thrust, so as to realize the chamfering function.

The inner wall of the front end of the accommodating hole 4 is fixedly provided with a limiting block 401, and the limiting block 401 is positioned in front of the cutter outlet hole 402 and is used for extruding the bending part of the elastic support 501.
