It to outside claw mounting hole, and is then resisted against on top plate by spring close to one end of top plate, the claw is in short transverse
Centre offers a bayonet, and the position of the bayonet is corresponding with the position in handle of a knife hole, and bayonet length direction away from
From the aperture more than handle of a knife hole, taper card base is equipped on the wall body of the bayonet and close to the side of spring；Described rushes
Head is made of cutter and calibration ring, and the cutter is vertically fixed on the axial intermediate of calibration ring, on the handle of a knife of the narrow contracting of cutter
A card slot is offered, the punch is coordinated by the handle of a knife hole of handle of a knife and the punch holder to be installed, and by the cone in bayonet
Shape card base and the scarf of the card slot on handle of a knife and realize being quickly fixedly connected between punch and punch holder.
In the specific embodiment of the present invention, the punch holder is further opened in the side of short transverse on one
The claw limit hole of lower perforation, the claw limit hole are vertical setting and are interconnected with the claw mounting hole；Described
Claw offers one up and down at the position corresponding to claw limit hole and in the claw limiting slot of strip, described
A gag lever post is arranged in claw limit hole, one end of the gag lever post extends downward into claw mounting hole and probes into the card
In the claw limiting slot of pawl, claw is limited in claw by the cooperation of gag lever post and claw limiting slot length direction both ends end face
The stroke to horizontally slip in mounting hole.
In another specific embodiment of the present invention, the punch holder is opened on the side side for being equipped with top plate
Equipped with a top plate caulking groove, multiple screw holes are further opened in the punch holder around the top plate caulking groove, the top plate, which is embedded, to be pushed up
In plate caulking groove, screw is separately installed in the screw hole, the nut edge clinching of the screw realizes top plate on top plate
With being fixedly connected for punch holder.
In another specific embodiment of the present invention, the calibration ring is made of calibration ring seat and limited block, institute
In a state of use towards a limiting slot is offered on the side side of punch holder, the limited block is embedded the calibration ring seat stated
In the limiting slot, and limited block is projected on the upper surface of calibration ring seat；Punch holder direction in a state of use
Offered along its length on the side side of punch one or so perforation punch holder limiting slot, the limited block punch with
In the installation process of punch holder, when the left or right side of punch holder limiting slot length direction and limited block scarf, it can be achieved that punching
Commutation of the head in punch holder.
In another specific embodiment of the present invention, the upper surface of the punch holder is an inclined surface, the inclination
Angle between face and horizontal plane is 5 ° or 10 °.
The present invention with the above structure, has the advantage that：It is matched with punch holder firstly, since using claw
Structure fix punch, need to only push or discharge one end of claw when mounted, spring-compressed or reset is made to can be realized
Shirking between the handle of a knife and punch holder of punch connects, and to substantially increase the clamping speed of cutter, and reduces cutter
Clamping difficulty；Secondly as the inclined surface with certain angle is provided in the upper surface of punch holder, because without adjusting tooling
Angle, as long as according to the different punch holders with different angle inclined surface that needs replacing, install convenient and precision height make
Use long lifespan；Third can be real by the cooperation of the left or right side of the limited block and punch holder limiting slot length direction of calibration ring
Existing quick commutation of the punch in punch holder；4th, overall structure is relatively simple, can substantially reduce the production difficulty and system of tooling
Cause this.
