Fig. 1 is a schematic structural view of the present invention;

FIG. 2 is an internal schematic view of the movable clamping mechanism;

fig. 3 is a schematic view of the structure of the open state of the present invention.

In the figure, 1, fixing plate; 2. a guide plate; 3. a movable seat; 4. a mounting plate; 5. a spring pin; 6. a compression plate; 7. positioning pins; 8. an elastic device; 9. a fastener; 10. a pin shaft; 11. a groove; 12. the plate is fixed.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

as shown in fig. 1, the rapid positioning and clamping device comprises a fixed plate 1, a spring pin 5 is arranged on the fixed plate 1, the spring pin 5 penetrates through the fixed plate 1, a pin shaft 10 is arranged at the upper part of the spring pin 5, the axis of the pin shaft 10 is perpendicular to the axis of the spring pin 5, two sides of the pin shaft 10 are hinged to a movable clamping mechanism, the movable clamping mechanism comprises a movable seat 3, a pressing plate 6 and a groove 11 matched with the spring pin 5 are arranged on the movable seat 3, an elastic device 8 and a fastening piece 9 are arranged at the lower part of the spring pin 5, the upper part of the elastic device 8 is in contact with the bottom of the fixed plate 1, the lower part of the elastic device 8 is in contact with the fastening piece 9, the elastic device 8 adopts a spring; two sides of the movable clamping mechanism on the fixed plate 1 are respectively provided with a guide plate 2 which is fixedly connected; the fixing plate 1 is provided with a positioning pin 7.

As shown in fig. 2, the movable seat 3 includes an L-shaped bending plate with a round angle, a groove 11 matched with the spring pin 5 is formed in the bottom and the side of the L-shaped bending plate, support plates 4 are respectively arranged on two sides of the L-shaped bending plate, and two sides of the pin shaft 10 are hinged to the support plates 4.

As shown in fig. 1, in use, the clamping force of the elastic device 8 on the pressing plate 6 is adjusted by adjusting the fastening member 9.
