Detailed Description

Preferred embodiments of the present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 to 4, the pressing tool includes a pressing plate 1, a housing 2, a connecting shaft 3, a pressure indicating pin 4 and a hand rest 5, wherein the connecting shaft 3 is connected with the pressing plate 1 through a bolt 13, the connecting shaft 3 extends into the housing 2, an elastic member is arranged in the housing 2, and the connecting shaft 3 is connected with the hand rest 5 through the elastic member; the connecting shaft 3 is connected with a pressure indicating pin 4; the side wall of the shell 2 is provided with a window, the pressure indicating pin 4 extends out of the window, and one side of the window of the shell 2 is provided with an indicating line.

The elastic component comprises a spring 6 and a pressure adjusting stud 7, the pressure adjusting stud 7 is in threaded connection with the upper end of the shell 2, the spring 6 is located in the shell 2, one end of the spring 6 is in contact with the connecting shaft 3, the other end of the spring 6 is in contact with the pressure adjusting stud 7, and the hand rest 5 is connected with the pressure adjusting stud 7. The spring 6 is a constant stiffness spring 6.

The shell 2 is connected with a light touch switch 9 through a damper 8, the light touch switch 9 is electrically connected with a battery 10, an indicator light 11 or a buzzer, and the light touch switch 9 is positioned above the pressing plate 1. When the bottom of the damper 8 contacts the tact switch 9, the pressure indicating pin 4 is located at the upper pressure limit indicating line. The indicating lines are scale marks.

The damper 8 is of a type with a pressure value close to the operating force of the tact switch 9, so that the tact switch 9 is protected, and the service life of the switch is guaranteed. In addition, the height of the damper 8 can be adjusted through the nut of the damper 8 to adapt to different models of tact switches 9. The battery 10 adopts a button battery 10, the indicator light 11 and the tact switch 9 can be 3V or 5V rated voltage types which are common in the market, and the circuit is in a series connection mode.

The surface of the pressing plate 1 is provided with a protective layer 12. The material of the protective layer 12 is latex. The housing 2 is cylindrical.

In this embodiment, the part of the tool applying force to the product is the pressing plate 1, and a layer of latex is adhered to the surface of the pressing plate 1, so that the surface of the label part can be protected, and stress concentration caused by unevenness of the part can be reduced.

Next, the pressure can be quantitatively adjusted by adjusting the pressure adjusting stud 7 using the spring 6 having a constant stiffness of the spring 6. As shown in fig. 5, the stiffness of the spring 6 is c, and the free length L of the spring 6 is L; adjusting the screw pitch of the stud to be 1 mm; the target pressure value Ft corresponds to the compression stroke d.
