The connecting rod mechanism is composed of a connecting rod, a power torsion spring, a rebound torsion spring, and a plastic seat of the connecting rod. The plastic seat of the connecting rod is connected with the pressing cover and the connecting rod. The power torsion spring and the connecting rod are fixed between the two outer covers, one end of the rebound torsion spring is fixed on the connecting rod and the other end is fixed on the main body, and the connecting rod front end hooks the blade.

A safety button is also fixed on the main body, and a safety hook is matched on the safety button, and the safety hook hooks the blade.

The nail pushing frame is provided with a nail pushing plate, the nail pushing plate is fixed on the nail pushing frame through a tension spring, the nail pushing frame is connected with a plastic frame, and the plastic frame is connected with the main body by buckling.

Steel sheets are fixed on the base.

The utility model is provided with a connection mechanism between the pressing cover and the main body, so it is very convenient to bind multiple pages of paper, and it is very labor-saving; when the paper is not bound, the safety button does not move, and the safety button, safety hook and blade will be locked together , the nail cannot be driven out, which can avoid the user from being injured due to wrong operation of driving out the nail. The utility model has the characteristics of labor saving and safety, and is suitable for popularization and application.

Description of drawings:

Below in conjunction with accompanying drawing, the utility model is further described:

Fig. 1 is the assembly schematic diagram of the present utility model;

Detailed ways:

See accompanying drawing 1, the utility model comprises: Base 1, main body, the press cover 2 that is movably connected on the main body, the main body is surrounded by two outer covers 3,4 and forms, and when two outer covers 3,4 are buckled together, a bottom is formed Space, the space is inserted with a push nail frame 5, the push nail frame 5 is connected with a plastic frame 16, and the plastic frame 16 is connected with the main body by buckling.

The main body is connected with the pressing cover 2 through a link mechanism, and the link mechanism is connected with the blade 6 . The blade 6 is used to drive out the nails in the nail pushing frame 5 .

Described link mechanism is made up of connecting rod 7, power torsion spring 8, rebound torsion spring 9, connecting rod plastic seat 10. The connecting rod plastic seat 10 connects the pressing cover 2 and the connecting rod 7, that is, when the pressing cover 2 is pressed, the connecting rod 7 can be driven to move; the connecting rod 7 is placed in the middle of the power torsion spring 8, and the power torsion spring 8, The connecting rod 7 is fixed between the two outer covers 3 and 4, and the connecting rod 7 rotates around the pivot pin; the power torsion spring 8 is inserted on the blade 6; one end of the rebound torsion spring 9 is fixed on the connecting rod 7 and the other end is fixed On the main body; the front end of the connecting rod 7 hooks the blade 6.

A safety button 12 is also fixed on the main body, and the safety button 12 is positioned at the front end of the blade 6; The safety button 12 and the safety hook 13 are made of plastic material, and when the safety button 12 is pushed up, the blade 6 can be separated from the safety hook 13 .

The nail pushing frame 5 is provided with a nail pushing plate 14 , and the nail pushing plate 14 is fixed on the nail pushing frame 5 through a tension spring 15 .

A steel sheet 17 is fixed on the base 1, and the nails driven out can be nailed.

The nail is placed in the space formed under the two outer covers 3 and 4. When the nail pushing frame 5 is inserted, the nail pushing plate 14 is squeezed by the nail, and the extension spring 15 is compressed backward, so that the nail always has a forward tendency .

When pressing the cover 2 downward, the cover 2 pulls the connecting rod 7 upward through the connecting rod plastic seat 10, the connecting rod 7 pulls the blade 6 upward, the power torsion spring 8 is deformed, and the nail moves forward by one space; when the cover 2 is pressed When pressing down to the end, the power torsion spring 8 recovers, and the blade 6 is pressed down quickly, and the blade 6 drives out the nail. Due to the leverage of the connecting rod 7 and the elastic force of the power torsion spring 8, it is very labor-saving to bind multiple pages of paper.

In addition, only when the paper pushes up the safety button 12, the safety hook 13 releases the blade to drive out the nails. Therefore, when a wrong operation occurs, the user will not be hurt by driving out the nails, which is very safe.

The utility model has the characteristics of labor saving and safety, and is suitable for popularization and application.

Of course, the above-described embodiments are only preferred examples of the present utility model, and are not intended to limit the scope of implementation of the present utility model, so all equivalents done according to the structure, features and principles described in the scope of patent application for the present utility model Changes or modifications should be included in the patent scope of the utility model.
