The inside and outside planing tool of a kind of shaping tool described in the utility model and the fit structure of rear support body is characterized in that:
One external damping circle is located in the annular groove of handle tube rear end section inwall of outer planing tool, and an internal damping circle is located in the annular groove of rear support body leading section inwall;
The knife bar cylinder of interior planing tool stretches in the knife bar cylinder of outer planing tool, and shank of planing tool stretches in the leading section of described rear support body in this, and cooperates with described internal damping circle;
The leading section of described rear support body stretches in the handle tube rear end section of outer planing tool, and cooperates with described external damping circle.
Middle part in the inside and outside planing tool of described a kind of shaping tool and the fit structure of rear support body, its described rear support body is provided with square blind hole, rearward end is provided with circular blind hole, is provided with holddown spring in this circle blind hole; The shank forward end of described interior planing tool is provided with that friction washer, middle part are provided with annular projection, the rear portion is provided with square knuckle, and the square blind hole at the middle part in described square knuckle and the described rear support body cooperates.
The beneficial effects of the utility model:
(1) interior planing tool and outer planing tool are linked together by a kind of damping unit, and the knife bar cylinder of interior planing tool and outer planing tool does not contact mutually during work, but the knife bar cylinder of interior planing tool can not come off from the knife bar cylinder of outer planing tool;
(2) removable, convenient for cleaning between interior planing tool and the rear support body;
(3) holddown spring forces together outer planing tool and interior planing tool by friction washer, and outside support force is provided, and interior planing tool can not slide;
(4) friction washer can reduce the phase mutual friction between inside and outside planing tool, held stationary during use.
