The technical scheme adopted by the utility model is as follows: the utility model provides a hand-held stapler, includes base, nail way, upper cover, and nail way, upper cover all locate in the base and the afterbody articulates on the base, and the upper cover is installed on the nail way, and the front portion of upper cover is used for extrudeing the staple in the nail way, and the cover is located the upper cover top for exert pressure to the upper cover, the cover front portion articulated with the front portion of base, the cover below is installed down the pinch roller, the pinch roller is located the anterior top of upper cover down, the pinch roller is laminated with the upper cover upper surface, the cover is through pushing down the pinch roller and is pushed the upper cover motion.

As an improvement, a guide mechanism is adopted between the lower pressing wheel and the contact surface of the upper surface of the front part of the upper cover to realize matching.

Preferably, the guide mechanism is that the outer surface of the lower pressing wheel is provided with an annular guide groove, and the upper surface of the front part of the upper cover is provided with a guide rib matched with the annular guide groove. The guiding can be realized more smoothly.

The guide mechanism is characterized in that the outer surface of the lower pressing wheel is provided with an annular convex rib, and the upper surface of the front part of the upper cover is provided with a guide groove matched with the annular convex rib.

Preferably, the front part of the cover forms an accommodating cavity which is wrapped at the front parts of the base, the nail channel and the upper cover, and the tail part of the cover forms an arc-shaped surface which is convenient for holding. The guiding can be realized more smoothly.

The utility model has the technical effects that: compared with the traditional mode, the hand-held stapler disclosed by the utility model applies pressure in a lever mode, applies pressure to the upper cover of the staple track through the lower pressing wheel, and is combined with the lower pressing wheel type pressing mechanism, so that the hand-held stapler is labor-saving, is smoother to use, is not easy to clamp a shell, and is easy to rebound and reset.

Detailed Description

The following description is presented to disclose the utility model so as to enable any person skilled in the art to practice the utility model. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art.

As shown in fig. 1-5, implement one: the utility model provides a hand-held stapler, includes base 1, nail way 2, upper cover 3, cover 4, nail way 2, upper cover 3 all locate in the base 1 and the afterbody articulates on base 1, and upper cover 3 installs on nail way 2, and the front portion of upper cover 3 is used for extrudeing the staple in nail way 2, and cover 4 is located upper cover 3 top for exert pressure to upper cover 3, cover 4 anterior and base 1's front portion articulated, cover 4 installs down pinch roller 5 in the below, and lower pinch roller 5 is located upper cover 3 anterior top, and lower pinch roller 5 laminates with upper cover 3 upper surface, and cover 4 extrudes upper cover 3 through pinch roller 5 down and moves. In order to further improve the smoothness of the operation, a guide mechanism is adopted to realize the matching between the lower pressing wheel 5 of the upper cover and the contact surface of the upper surface of the front part of the upper cover 3. In this embodiment, the guiding mechanism of the upper cover means that the outer surface of the lower pressing wheel 5 is provided with an annular guiding groove 5.1, and the upper surface of the front part of the upper cover 3 is provided with a guiding rib 3.1 matched with the annular guiding groove 5.1. The guiding can be realized more smoothly.

Example two: the utility model provides a hand-held stapler, includes base 1, nail way 2, upper cover 3, cover 4, and nail way 2, upper cover 3 all locate in the base 1 and the afterbody articulates on base 1, and upper cover 3 is installed on nail way 2, and the front portion of upper cover 3 is used for extrudeing the staple in the nail way 2, and cover 4 is located upper cover 3 top for to upper cover 3 applanation force, the front portion of cover 4 articulated with base 1, press wheel 5 is installed down to cover 4 below, press wheel 5 is located upper cover 3 anterior tops down, press wheel 5 and the laminating of 3 upper surfaces of upper cover down, cover 4 extrudes the motion of upper cover 3 through press wheel 5 down.
