Referring to fig. 1 and 2 together, the staple pushing mechanism is applied to a staple channel 50 of a stapler for pushing a staple body forward along the staple channel 50. The nail pushing mechanism comprises a nail pushing piece and a force guiding piece 10, wherein the nail pushing piece is used for being abutted with a nail body in the nail channel 50 to push the nail body forwards and horizontally. The force guide member 10 is disposed at an upper end of the nail pushing member, and is used for converting pressure in a vertical direction applied to the nail pushing member into horizontal thrust.

The staple body may be a staple, wherein the size of the staple may be selected based on the size of the staple channel 50.

It can be understood that by arranging the force guide member 10 at the upper end of the nail pushing member, when the force guide member 10 receives pressure, the pressure in the vertical direction of the force guide member can be converted into a horizontal backward thrust force, so that the nail pushing member is prevented from being damaged due to pressing, and the protection of the nail pushing member is improved.

In some specific embodiments, the staple pusher may include a pusher 20 and a spring 30. The upper end of the push block 20 is provided with a force guide member 10, and the push block 20 is movably arranged in the nail path 50 back and forth to push the nail body. The elastic member 30 acts on the push block 20 and applies elastic force in the horizontal direction to the push block 20.

It will be appreciated that the elastic member 30 applies a force in a horizontal direction to always push the staple toward the front end of the throat 50, so as to facilitate stapling of the staple to papers, books, etc.

Further, the staple pusher may also include a guide bar 40. Wherein the guide bar 40 is horizontally disposed in the staple channel 50, and the guide bar 40 passes through the push block 20, thereby movably moving the push block 20 along the guide bar 40.

In an embodiment, the guide rod 40 may be a cylindrical structure or a square cylindrical structure, and is fixed at the rear end of the nail channel 50, and a through hole is formed in the middle of the push block 20, and the shape of the through hole is adapted to the cylindrical structure of the guide rod 40, so that the push block 20 can pass through the guide rod 40 and move back and forth in the guide rod 40, thereby facilitating the placement of the nail body into the nail channel 50 when the push block 20 moves to the rear end of the nail channel 50. After the nail body is installed, the pushing block 20 can push the nail body to the front end of the nail channel 50 under the action of the elastic piece 30, so that the subsequent stapler can conveniently bind.

In one embodiment, the elastic member 30 may be a spring. The spring may be disposed around the outside of the guide bar 40 and act on the push block 20 to push the push block 20 in the direction of the nail body.

Further, the force guide 10 is disposed at an end of the push block 20 near the staple outlet of the staple channel 50.

It can be appreciated that when the pressing piece 60 presses the nail body in the nail channel 50, since the pressing piece 60 is aligned with the nail outlet of the nail channel 50, the nail pushing member is easily pressed in the process of pressing the nail body, so that the force guiding member 10 is arranged at the upper end of the pushing block 20 near the position of the nail outlet of the nail channel 50, the nail pushing body can be effectively protected, and the damage to the nail pushing body caused by false pressing is avoided.

The upper end of the force guide member 10 includes an inclined surface facing in the direction of the staple outlet.

It will be appreciated that when the pressing plate 60 presses the staple pusher, which is the first to press the force guide 10, the inclined surface of the force guide 10 will split the pressure applied by the pressing plate 60 into a horizontal force (i.e. along the extending direction of the staple channel 50) so as to reduce damage to the parts of the stapler caused by excessive pressing of the pressing plate 60 during use.

Further, the angle between the force guide 10 and the horizontal plane may be in the range of 15 ° to 80 °.

Referring to fig. 3 and 4, based on the above-mentioned concept of the staple pushing mechanism, the present patent further provides a stapler 100. The stapler 100 includes: the above-described staple pushing mechanism, staple channel 50, and pressing piece 60 (see fig. 1). The nail path 50 is used for placing a nail body, a nail outlet is formed in the bottom of the front end of the nail path 50, and the pressing piece 60 is aligned to the nail outlet and used for pressing the nail body from the nail path 50 to the outside of the nail outlet so as to bind bound objects.

It should be noted that, the specific structure of the nail pushing mechanism may be referred to above, and will not be described herein.

When the pressing sheet 60 presses the nail pushing mechanism, the force guide member 10 is firstly pressed, and the force guide member 10 converts the pressure applied by the pressing sheet 60 into horizontal pushing force so as to enable the nail pushing mechanism to push away from the pressing sheet 60, so that the pressing sheet cannot contact other parts of the nail pushing mechanism.

Wherein the width of the pressing piece 60 is smaller than or equal to the nail outlet.

The terms and expressions which have been employed herein are used as terms of description and not of limitation. The use of these terms and expressions is not meant to exclude any equivalents of the features shown and described (or portions thereof), and it is recognized that various modifications are possible and are intended to be included within the scope of the claims. Other modifications, variations, and alternatives are also possible. Accordingly, the claims should be looked to in order to cover all such equivalents.

Also, it should be noted that while the present utility model has been described with reference to the particular embodiments presently, it will be appreciated by those skilled in the art that the above embodiments are provided for illustration only and that various equivalent changes or substitutions may be made without departing from the spirit of the utility model, and therefore, the changes and modifications to the above embodiments shall fall within the scope of the claims of the present utility model as long as they are within the true spirit of the utility model.
