CN2915423Y - Coil binder clip for limiting pushing broach - Google Patents

Abstract

The utility model relates to a limit clip of the press blade in wire binding machines. In existing technology, the limit device relies on manual operation to limit position when working, which may easily cause failure when the press blade doesn't arrive at the limited position when it is inserted or pulled out. This utility model contains a V shaped clip itself, the section of one arm of which is a trapezium with opened bottom line, wherein the two inclined planes are designed inwardly to form a limit plane. An upper and a lower clip keys are equipped on the other arm of the clip itself. Since the section of one arm of the clip is a trapezium with opened bottom line, when the press blade is inserted or pulled out, the limit pin on the press blade moves on its outer side face, and when it moves to the limit plane, it will slide outward automatically to make the press blade arrive at the limited position.

Description

The spacing clamp of coil binder push type broach sheet

Technical field

The utility model relates to a kind of limiting component, the spacing clamp 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 spacing clamp of push type broach sheet that need limit the position of the push type broach sheet can being sent to when inserting or extract the push type broach sheet out.

The utility model comprises V-type clamp body, and the cross section of an arm of body is the trapezoidal of base opening, and wherein two inclined-planes inwardly are provided with the formation confined planes.The top of another arm of body is provided with the screens key, and the middle part is provided with down the screens key, and the bottom of last screens key is corresponding with the width of push type broach sheet with the vertical range at the top of following screens key.

The spacing clamp of push type broach sheet of the present utility model is stuck between the two push type broach sheets, and a side arm limits the position between itself and push type broach sheet by upper and lower screens key.Because of the cross section of another arm of clamp is open trapezoidal in base, when the push type broach sheet when inserting or extract out, the spacer pin on the push type broach sheet moves at its lateral surface, outwards slides automatically when moving to confined planes, thereby guarantee that spacer pin touches pressure knife or takes out knife rest, and make 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, the spacing clamp of binder push type broach sheet comprises V-type clamp body 1, and the pressure knife and the distance of taking out between the knife rest are corresponding in the width of body 1 and the binder.The cross section of one arm of body 1 is the trapezoidal of base opening, and wherein two inclined-planes inwardly are provided with and form confined planes 4.The top of another arm of body 1 is provided with screens key 3, and the middle part is provided with down screens key 2, and the bottom of last screens key 3 is corresponding with the width of push type broach sheet with the vertical range at the top of following screens key 2.

In the work the spacing clamp of push type broach sheet is stuck between the two push type broach sheets, a side arm is stuck in the side arm of a push type broach sheet by last screens key 3 and following screens key 2 with it, and another side arm contacts with adjacent push type broach sheet.Because of the cross section of another arm of clamp is open trapezoidal in base, when the push type broach sheet that is in contact with it when inserting or extract out, spacer pin on the push type broach sheet moves at its lateral surface, automatically outwards slide when moving to confined planes 4, thereby guarantee that spacer pin touches pressure knife or takes out knife rest, and make the push type broach sheet arrive the position that limits.

Claims (1)

1, the spacing clamp of coil binder push type broach sheet comprises V-type clamp body (1), and the cross section that it is characterized in that an arm of body (1) is the trapezoidal of base opening, and wherein two inclined-planes inwardly are provided with and form confined planes (4); The top of another arm of body (1) is provided with screens key (3), and the middle part is provided with down screens key (2), and the bottom of last screens key (3) is corresponding with the width of push type broach sheet with the vertical range at the top of following screens key (2).
