Description

[Detailed description of the invention] Roughly divided, a holding rod B that stores and progressively feeds the stitching needle, a pressing rod C1 that presses the stitching needle, and a needle receiving bent base A are loosely fastened with studs O. By adding the stopper device of the present invention to a stapler for whitening filter paper, the main objective is to quickly, accurately, and freely set the depth of the stapler at the desired position for whitening paper. This is what I did.

If the embodiment of the present invention is explained with reference to the drawings, the needle receiving bent part A
By bending both sides except for the needle receiving bent part A3 into a U-shape facing each other, a transition path A4 for the stopper element X is provided, and on both sides of the needle receiving bent part A3 and the proximal end of the needle receiving bent base A. Cut an appropriate number of saw blade-shaped restriction grooves A1 at the same size on the upper side of the transition path between the vertically erected linking blades A2 to provide a stop for the rising part X1 of the stopper element X. .

The stopper element X performs several functions, namely, it bends one axis into an open U-shape with the same size on the left and right sides, and then bends both ends of it at the same size and at right angles to form the rising part x,... x1 is provided to control the entire stopper element.

Rising portion X1 of stopper element X. X is the grip when the paper is white and the stopper X is moving,
l.

The lower part of Xl is a portion X2 that fits into the restriction groove A1. x2 is a part that fulfills its role as a spring.

The preparation operation when using a book or stapler is to pinch the upper part of That is, the rising part x1 of the stopper element X. The X1 is semi-automatically fitted into the restriction groove A1 of the needle receiving curved portion A at the same size and is used for paper white binding.

The effect is that the edge of the paper to be bound is placed on the rising part of the stopper
,,x1 and press the pressure rod C, there is no concern that the staples will be distorted, the position of the staples remains accurately, and the paper white binding operation can be completed quickly.

This stapler is a new idea that can achieve great results by adding a saw-blade-like notch to the needle-receiving bent part of the conventional product and adding a small stopper element as shown in Figure 2. .

[Brief explanation of the drawing]

FIG. 1 is a perspective view of the entire device, FIG. 2 is a perspective view of the stopper element, FIG. 3 is a sectional view taken along line S-3, and FIG. 4 is a plan view of the stopper element and the needle receiver bending portion. A is the needle receiving curved portion, B is the staple holding rod, C is the pressing rod, X is the stopper element, O is the rivet, A1 is the restriction groove, A2 is the linking wing, n is the needle receiving curved portion, and A4 is the top surface of the transition path. , C1 is the needle driving claw, xl is the rising part, X2 is the spring part, and XX is the posture of the stopper element transition.

Claims (1)

[Scope of utility model registration request] In a paper stapler, both sides of the needle holder except for the bent part of the needle holder are bent into a U-shape that faces each other to create a transition path for the stopper piece described later, and the needle holder is bent and the needle holder is bent. An appropriate number of saw blade-shaped restriction grooves were cut on the upper side of the transition path between the linking blades vertically installed on both sides of the proximal end of the bending table, and the wire was bent into a U-shape to form the spring part. A stopper device for a stapler, characterized in that a spring part of a stopper element whose both ends are bent at the same angle at the same angle to form a rising part is inserted into the transition path.
