This invention relates to stationary accessories.

The purpose of the invention is to improve ease of use and simplify the design.

FIG. 1 shows a device, a longitudinal section, in the working position; in fig. 2 is the same in the position for placing the sheet.

The device for securing the sheet material 1 comprises a hollow cylindrical body 2 mounted in the body with the possibility of reciprocating movement of a spring-loaded hollow cylindrical brush 3 having, on one of the end sides, a head 4 for clamping the sheet material 1, and a spring-loaded pusher 5 disposed in the stem cavity 3

The rod 3 on the other hand has a flange 6,

and its spring 7 is coaxial

with rod 3 with the ability to interact

with a flange 6 for holding the rod while clamping the sheet material 1.

The spring 8 of the pusher 5 is disc-shaped and with its convex part facing the pusher so that it can interact with the flange of the rod 3 to move the latter and form a gap 9 between the head 4 and the end surface of the body 2 when placing the sheet material 1.

The contacting surface of the head 4 and the end surface of the housing 2 are interconnected pincers 10 and depressions 11.

The device is used as follows.

To fix the sheet material 1, the pusher 5 is pressed, which cooperates with the spring 8, straightens it, while the peripheral section of the spring interacts with the flange 6 of the rod 3 and displaces the latter. Sheet material 1 is introduced into the resulting gap 9.

When you release the pusher 5, the spring 7 moves the brush 3, the head 4 of which presses the sheet material 1 to the end surface of the housing 1.

Claims (2)

1. A device for securing sheet material, comprising a hollow cylindrical body mounted in the case with a reciprocating movement of a spring-loaded hollow cylindrical rod having, on one of the face sides, a head for clamping the sheet material, and a spring-loaded pusher disposed in the cavity of the rod, characterized 0 in order to improve ease of use and simplify the design, the brush on the other front side has a flange, and its spring is located coaxially with a brush with the ability to interact with 5, the flange for moving the brush when clamping the sheet material, the pusher spring is made disc-shaped and with its convex part toward the pusher with the possibility of interacting with the flange of the brush to move the latter and forming a gap between the head on the front surface of the housing when placing the sheet material. 2. The device according to claim., Characterized in that the contacting surfaces of the head of the stem and housing have interacting 5 between the thorns and hollows. Board
