Abstract

The utility model discloses a pressing knife structure of a scattered-knife punching binding machine. The pressing knife structure comprises scattered knives, a knife pressing plate, a guide mechanism, a left support and a right support, wherein the guide mechanism comprises an upper leading-in plate and a lower leading-in plate, the lower ends of the scattered knives are inserted into the guide mechanism, the upper ends of the scattered knives are connected with the knife pressing plate, and protruding ribs are arranged in the positions, corresponding to the scattered knives respectively, of the knife pressing plate. The pressing knife structure of the scattered-knife punching binding machine has the advantages of being simple in structure, convenient to machine and use and high in assembly efficiency.

Description

A kind of push type broach structure of loose cutter perforating binding machine

Technical field

The utility model relates to the binder field, specifically refers to a kind of push type broach structure of loose cutter perforating binding machine.

Background technology

At present, the push type broach structure of loose cutter perforating binding machine comprises loose cutter, handle and is riveted on by two or three-piece metal plate the hold(ing)-down clip assembly formed on hold(ing)-down clip, the forwards fixed handle drive square shaft and on shifting block rotate the mode that presses down the hold(ing)-down clip assembly and realize that loose cutter moves down and punched, this kind of design can realize the demand of loose cutter punching, yet its processing and manufacture difficulty are high, wayward precision, inconvenient operation, complex structure and cost are high.

The utility model content

The purpose of this utility model is to provide the push type broach structure of a kind of simple in structure, processing and loose cutter perforating binding machine easy to use, that efficiency of assembling is high.

To achieve these goals, the utility model is designed a kind of push type broach structure of loose cutter perforating binding machine, comprise loose cutter, hold(ing)-down clip, guiding mechanism, left socle and right support, described guiding mechanism comprises importing plate and lower importing plate, described loose cutter lower end is inserted in guiding mechanism, upper end is connected with hold(ing)-down clip, and position corresponding with loose cutter on described hold(ing)-down clip is provided with convex tendon.

Described convex tendon is that the avulsion bending forms.

Described loose cutter upper end is provided with draw-in groove, and described hold(ing)-down clip lower end is provided with the fixture block matched with draw-in groove.

Described hold(ing)-down clip upper end is provided with baffle plate.

Be respectively equipped with the spacing hole moved up and down for hold(ing)-down clip on described left socle and right support.

The beneficial effect of the push type broach structure of the loose cutter perforating binding machine of the utility model: adopt the direct convex tendon that the avulsion bending forms on hold(ing)-down clip as the push type broach position of bone, the mode that substitutes push type broach assembly of the prior art with the hold(ing)-down clip that the is provided with convex tendon cutter push type broach that fall apart punches, have advantages of simple in structure, processing and easy to use, efficiency of assembling is high.

the accompanying drawing explanation:

Fig. 1 is the decomposing schematic representation of the push type broach structure of the loose cutter perforating binding machine of the utility model;

Fig. 2 is the structural representation of hold(ing)-down clip in Fig. 1;

Fig. 3 is the structural representation of loose cutter in Fig. 1.

The specific embodiment

For the ease of those skilled in the art's understanding, below in conjunction with specific embodiment and accompanying drawing, structural principle of the present utility model is described in further detail.

As shown in Figure 1 to Figure 3, a kind of push type broach structure of loose cutter perforating binding machine, comprise loose cutter 4, hold(ing)-down clip 5, guiding mechanism, left socle 6 and right support 11, described guiding mechanism comprises importing plate 3 and lower importing plate 2, described loose cutter 4 lower ends are inserted in guiding mechanism, upper end is connected with hold(ing)-down clip 5, described hold(ing)-down clip 5 adopts Sheet Metal Forming Technology to make, position corresponding with loose cutter 4 on described hold(ing)-down clip 5 is provided with convex tendon 14, described convex tendon 14 forms for the avulsion bending, described loose cutter 4 upper ends are provided with draw-in groove 15, described hold(ing)-down clip 5 lower ends are provided with the fixture block 13 matched with draw-in groove 15, described hold(ing)-down clip 5 upper ends are provided with baffle plate 12, be respectively equipped with the spacing hole 10 moved up and down for hold(ing)-down clip 5 on described left socle 6 and right support 11.

As shown in Figure 1, the operation principle of the push type broach structure of the loose cutter perforating binding machine of the utility model: at first will need the paper of bookbinding or file to put on the support 1 of introducing mechanism below, handle 9 is pressed down to shifting block 8 rotations that drive on square shaft 7 to positive direction to be pressed on hold(ing)-down clip 5, hold(ing)-down clip 5 moves downward, convex tendon 14 on it is one by one on the loose cutter of push type broach punching, thereby realizes punching functions, and it is simple in structure, processing and easy to use, efficiency of assembling is high.

Foregoing, be only preferred embodiment of the present utility model, and not for limiting embodiment of the present utility model, those skilled in the art are according to design of the present utility model, and the appropriate adaptation of having done or modification, all should be within protection domain of the present utility model.
