Abstract

A stapler capable of preventing mis-assembly of staples comprises a staple channel, a pull rod and a pressing handle, wherein the rear end of the pressing handle is rotatably connected with the rear end of the staple channel, a staple pushing block is connected in the staple channel in a sliding manner, one end of the pull rod is rotatably connected with the pressing handle, and the other end of the pull rod is connected in the staple channel in a sliding manner and is positioned in front of the staple pushing block; the nail path is characterized in that stop blocks are respectively arranged on the inner walls of the two sides of the front end of the nail path, and the distance between the lower end of each stop block and the inner wall of the bottom of the nail path is 6-8 mm. The stopper can allow 24/6 of the staples to pass through, but blocks 24/8 of the staples, and the 24/8 of the staples cannot reach the front end of the staple path, so that the stapler empties the staples. The advantage over the prior art is that the stapler will empty when a 24/8 staple is misloaded, thus allowing the user to know that the installed staple is faulty for immediate replacement.

Description

Stapler capable of preventing wrong staple installation

Technical Field

The utility model relates to a binding tool field especially relates to stapler.

Background

The staple is divided into several specifications, including 24/6 and 24/8 staple, the staple width of the two specifications is the same, and the staple angle height is different by 2mm. Due to the consistent width, 24/8 staples can also be placed in the staple path of a 24/6 stapler. The 24/6 stapler is generally a small stapler, and after a wrong staple is installed, the handle pressing force is insufficient and cannot be pressed, and because the height of the 24/8 staple is 2mm higher than that of the 24/6 staple, the lower end of a draw bar of the stapler can support the staple, so that when a user presses a top cover, a draw bar of the stapler is bent and deformed, and the stapler cannot be used.

SUMMERY OF THE UTILITY MODEL

The utility model provides a stapler of wrong nail of loading prevention to above problem.

The utility model provides a used technical scheme of above problem is: a stapler capable of preventing mis-assembly nails comprises a nail channel, a pull rod and a pressing handle, wherein the rear end of the pressing handle is rotatably connected with the rear end of the nail channel, a nail pushing block is connected in the nail channel in a sliding mode, one end of the pull rod is rotatably connected with the pressing handle, and the other end of the pull rod is connected in the nail channel in a sliding mode and is positioned in front of the nail pushing block; the nail path is characterized in that the inner walls of two sides of the front end of the nail path are respectively provided with a stop block, and the distance between the lower end of the stop block and the inner wall of the bottom of the nail path is 6-8 mm.

The utility model discloses the product stapler establishes the dog at the staple track front end, and the dog can let 24/6's staple pass through, but blocks 24/8's staple, and 24/8's staple can't reach the staple track front end, so the stapler empties the nail. After the structure is adopted, compared with the prior art, the stapler has the advantage that the empty staple can be punched after 24/8 of the staples are wrongly loaded, so that a user can know that the staples are wrongly loaded so as to replace the staples in time.

Preferably, an upward bending part is arranged at the end part of the other end of the pull rod. When the front end of the pull rod touches 24/8 nails, the bending part at the front end can guide the pull rod to the upper part of the staple, the pull rod can not prop against the staple, and the damage to the pull rod of the stapler when the press handle is pressed is avoided.

Preferably, the horizontal height difference of the lower end and the upper end of the bending part is more than 2mm.

Preferably, a gap is reserved between the stop block and the inner wall of the front end of the nail path.

Preferably, the inner walls of the two sides of the nail path are respectively provided with a sliding groove, the two sides of the other end of the pull rod are respectively provided with a sliding block, the sliding blocks are connected in the sliding grooves in a sliding mode, and the width of each sliding groove is at least 2mm larger than the thickness of each sliding block.

Fig. 2 is an explosion diagram of the stapler for preventing mis-stapling of the present invention.

Fig. 3 is a schematic structural view of the mis-staple prevention stapler of the present invention when 24/8 staples are installed.

As shown in the figure: 1. the nail pushing device comprises a nail channel, 11, a stop block, 12, a sliding groove, 2, a pull rod, 21, a bending part, 22, a sliding block, 3, a pressing handle, 4 and a nail pushing block.

Detailed Description

The invention is further described with reference to the accompanying drawings and the detailed description.

As shown in figures 1, 2 and 3, the stapler capable of preventing wrong-loading nails comprises a nail path 1, a pull rod 2 and a pressing handle 3, wherein the rear end of the pressing handle 3 is rotatably connected with the rear end of the nail path 1. The nail pushing block 4 is connected in the nail channel 1 in a sliding mode, and a spring is arranged between the nail pushing block 4 and the rear end of the nail channel 1 to enable the nail pushing block 4 to keep a forward trend. One end of the pull rod 2 is rotationally connected with the pressing handle 3, and the other end of the pull rod 2 is slidably connected in the nail channel 1 and positioned in front of the nail pushing block 4. When the pressing handle 3 is lifted, the other end of the pull rod 2 slides to the rear end of the nail channel 1 and drives the nail pushing block 4 to move backwards.

The inner walls of two sides of the front end of the nail channel 1 are respectively provided with a stop dog 11, and the distance between the lower end of the stop dog 11 and the inner wall of the bottom of the nail channel 1 is 6-8 mm.

A gap is reserved between the stop block 11 and the inner wall of the front end of the nail path 1.

The stopper 11 can let 24/6 of the staple pass through, but can block 24/8 of the staple, and the 24/8 of the staple cannot reach the front end of the staple channel 1, so that after the press handle 3 is pressed, the ejector on the press handle 3 is pressed in a gap between the stopper 11 and the inner wall of the front end of the staple channel 1, and the stapler empties the staple.

The end part of the other end of the pull rod 2 is provided with an upward bending part 21. The horizontal height difference of the lower end and the upper end of the bending part 21 is larger than 2mm.
