Further, the bit lower part is provided with groove three corresponding with blade, be provided in the groove three with Blade corresponding aduncate elastic block piece is provided with block corresponding with elastic block piece on the blade, is conducive to more preferable Fixed blade.

Further, the top of the bit is provided with groove four corresponding with gear, and the gear passes through in rotation Mandrel and four inner wall of groove are hinged, and the width that the diameter of the gear is greater than groove four is corresponding with the rack gear of one inner wall of groove., Be conducive to the length for the stretching knife handle for preferably adjusting blade

Further, the bit top is provided with connecting box, is correspondingly arranged on Rotary Connection block in the connecting box, The Rotary Connection block is connect with screw device, and the Rotary Connection block diameter is slightly less than connecting box internal diameter, the rotation connection The height of block is corresponding with the inside wall height up and down of connecting box, and through-hole corresponding with screw device, institute are provided on the connecting box Stating Rotary Connection block can rotate with screw device, be conducive to preferably passing through rotating screw devices stretching with cutting blade Contracting.

Further, datum-plane loop wire corresponding with graduation mark is provided on the screw device, convenient for preferably seeing Examine the stretching adjustment length of blade.

Further, the top of the screw device is divided into threaded portion, and lower part is divided into polished rod portion, the datum-plane loop wire In polished rod portion, color is red for setting, convenient for preferably setting datum-plane loop wire, convenient for preferably observing the stretching tune of blade Save length.

The utility model has the beneficial effects that

The utility model structure is simple, is provided with scale, can be very good the length that control scalpel stretches out knife handle, in turn Preferably control depth of cut, and grip part is provided with gripping finger ring, is conducive to better opponent and refers to be supported, be conducive to Make the stronger of gripping, and hand fatigue can be reduced.
