Handle of a knife, described handle of a knife is cylindrical, and the left end of described handle of a knife offers mounting groove, and described rotating seat is removable
It is connected in mounting groove with unloading, screwed hole is offered in the side wall of described handle of a knife left end, is connected with described screwed hole solid
Determine bolt, offer connecting hole relative to the position of screwed hole on the lateral wall of described rotating seat, described fixing bolt is worn
Screwed hole is crossed to be connected in connecting hole,
Elastic clamping structure, described elastic clamping structure are arranged between the outer wall of rotating seat and the inwall of mounting groove.
Further：Described elastic clamping structure include be opened on mounting groove inwall guide groove, be opened in rotating seat
Hemispherical neck, spherical dop and spring on outer wall, described spherical dop is connected in guide groove by spring, described
Spherical dop is caught in hemispherical neck under the action of the spring.
Further：Four hemispherical necks are uniformly offered on the outer wall of described rotating seat.
Further：Four connecting holes, described four connecting holes are also uniformly offered on the outer wall of described rotating seat
Intersect with four hemispherical necks and be evenly distributed on the outer wall of rotating seat.
Further：External connection screw is provided with the outer wall of one end that described cutter body is connected with rotating seat, it is described
Rotating seat cover be flexibly connected on the cutter body and with it, on the external connection screw of the cutter body of described rotating seat both sides
Respectively it is connected with an adjusting nut.
After said structure, the present invention can adjust the length that cutter body passes through rotating seat by rotating adjusting nut
Degree, so as to change the length that regulation cutter stretches out handle of a knife, serve the effect for increasing its practical performance；And the design also has
The advantages of simple in construction, easily fabricated and practicality and high efficiency.
