Side is provided through positioning bolt, and the side that the positioning bolt is located at tool sip inner cavity is fixedly connected with locating piece, described to put
The side that remotely located piece of cutter groove is fixedly connected with positioning plate, and the bottom of the tool sip offers fixing groove, on the body
And fixed plate is inlaid with positioned at the bottom of fixing groove, the both sides of the fixed plate are provided through fixing bolt, the fixation
The bottom of bolt is through to the outside of body, and the top of the fixing bolt is through to the inner cavity of fixing groove.
Preferably, the top and bottom of the handle of a knife offer lightening grooves.
Preferably, it is inlaid with metal ball on the left of the metallic rod.
Preferably, the both sides at the top of the tool sip are fixedly connected with connection ring by contiguous block.
The utility model possesses following beneficial effect：The double-blade boring cutter structure, by the improvement of boring cutter body, strengthens
The stability of boring cutter structure, avoid due to original paper hardness is excessive and stretch into speed it is relatively fast caused by boring cutter deviate, subtract
That has lacked substandard product occupies ratio, is improved work efficiency while reducing cost, facilitates the use of user.
