Abstract

The utility model relates to a caging device for push-type cutter blade of a coil binding machine. Current caging devices are manually operated, thus easily resulting in operation error because of the cutter clip insertion or withdrawal not to the designed positioned. The utility model fixes a U-shaped spring rack on the cutter withdrawal frame and moveably arranges a spring clip on the push-type blade. Both ends of the spring clip are respectively positioned below the U-shaped spring rack and above the spring clip. The utility model ensures the arresting pin contacts the cutter press or withdrawal frame during the cutter slip insertion or withdrawal, thus caging the cutter blade.

Description

Coil binder push type broach sheet stopping means

Technical field

The utility model relates to a kind of stopping means, the stopping means of the push type broach sheet in especially a kind of coil binder.

Background technology

The coil binder is the file punching of will be in sheets, and will wear edge strip (helical form iron wire or plastics silk) then and penetrate in the bookbinding hole.Can select that the coil binder that punches is general to adopt one the stamping knife correspondence is provided with the form of a push type broach sheet.As long as extract corresponding push type broach sheet out, the stamping knife of this push type broach sheet correspondence does not promptly participate in punching in the work, has realized the needs of various selectivity punchings.The push type broach sheet should make the push type broach sheet place rational position when inserting or extracting out.The stopping means of existing push type broach sheet is at push type broach sheet sidewall spacer pin to be set, and by pressure knife with take out knife rest and carry out spacingly, is provided with amortisseur bar simultaneously and contacts with the push type broach sheet, makes things convenient for the insertion or the extraction of push type broach sheet.But this kind stopping means relies on by hand fully at work and finishes, and inserts or extracts out the position that arrives qualification easily because of the push type broach sheet and work mistake occurs.

Summary of the invention

The purpose of this utility model just provides a kind of push type broach sheet stopping means that need limit the position of the push type broach sheet can being sent to automatically when inserting or extract the push type broach sheet out.

The utility model comprises and pressure knife and take out knife rest has the push type broach groove on the pressure knife, takes out on the knife rest correspondence and has and take out the cutter groove, and the push type broach sheet passes the push type broach groove respectively and takes out cutter groove adjustable shelf and is located at pressure knife and takes out in the knife rest, and the side of push type broach sheet is fixed with spacer pin.U type spring is pressed frame one arm and is taken out knife rest and fixedly connected, and another arm stretches into pressure knife and takes out between the knife rest.The spring clip adjustable shelf is located at the top of push type broach sheet, and the two ends of spring are placed on respectively in the U type spring pressure frame and stretch into pressure knife and take out the bottom of an arm between the knife rest and the top of spring clip.

U type spring presses frame to stretch into pressure knife and the corresponding push type broach sheet position, top of taking out the arm between the knife rest is provided with projection, can make things convenient for the setting of spring like this.The spring clip top is provided with projection, and the bottom is provided with depression, can make things convenient for the setting of spring so on the one hand, can make things convenient for spring clip setting up on the push type broach sheet on the other hand.

The push type broach sheet passes the push type broach groove respectively and takes out the setting of cutter groove in the utility model, spacing when the spacer pin by the side inserts or extracts out.The push type broach sheet guarantees that by spring action spacer pin touches pressure knife or takes out knife rest when inserting or extract out, and makes the push type broach sheet arrive the position that limits.

Description of drawings

1. Fig. 1 is a structural representation of the present utility model.

The specific embodiment

As shown in Figure 1, coil binder push type broach sheet stopping means comprises pressure knife 1 and takes out knife rest 3, have push type broach groove 6 on the pressure knife 1, taking out on the knife rest 3 correspondence has and takes out cutter groove 5, push type broach sheet 4 passes push type broach groove 6 respectively and takes out cutter groove 5 adjustable shelfs and is located at pressure knife 1 and takes out in the knife rest 3, and the side of push type broach sheet 4 is fixed with spacer pin 7.U type spring is pressed frame 2 one arms and is taken out knife rest 3 and fixedly connected, and another arm stretches into pressure knife 1 and takes out between the knife rest 3, and its correspondence push type broach sheet 4 positions, top are provided with projection.Spring clip 8 adjustable shelfs are located at the top of push type broach sheet 4, and its top is provided with projection, and the bottom is provided with depression.The two ends of spring 9 are placed on U type spring respectively and press the projection of frame 2 one arms and the projection at spring clip 8 tops.

Push type broach sheet 4 is when inserting or extract out, and by manually the push type broach sheet being inserted or extracts out, spring 9 was compressed before this.When spacer pin 7 at pressure knife 1 with when taking out centre position between the knife rest 3, spring 9 is by maximum compression, and by behind this position, the spring of compression discharges elastic force, guarantee that under the effect of spring 9 spacer pin 7 touches pressure knife 1 or takes out knife rest 3, and make push type broach sheet 4 arrive the position that limits.
