FIG. 3 is an enlarged schematic view of a portion of FIG. 2A;

FIG. 4 is a schematic view of the connection of the slider and the clamping plate of the present utility model.

In the figure: 1. a base; 2. a clamping plate; 3. a chute; 4. a slide block; 5. a hydraulic cylinder; 6. a movable groove; 7. a movable block; 8. a limit column; 9. a lock nut; 10. and (5) connecting bolts.

Detailed Description

The utility model will now be further described by way of specific examples with reference to the accompanying drawings, which are given by way of illustration only and not by way of limitation.

Referring to fig. 1-4, the present utility model provides a technical solution: the front end of the limit post penetrates through the movable groove and extends to the outer part of the movable groove.

The locking nuts and the movable grooves are in one-to-one correspondence.

One side of the two connecting bolts, which are opposite, penetrates through the base and the two locking nuts and extends to the outer parts of the locking nuts, and the connecting bolts are in threaded connection with the locking nuts.

The movable groove and the base are designed integrally, and an intercommunication type design is adopted between the movable groove and the sliding groove.

The rear end of the sliding block penetrates through the sliding groove and extends to the inside of the base, and the sliding block is in sliding connection with the sliding groove.

The sliding groove and the base are integrally designed, and the rear surface of the clamping plate is contacted with the base.

Working principle: when the device is used, a user places a workpiece on the base 1, then the hydraulic cylinder 5 is started to push the sliding block 4 to slide, the clamping plate 2 is driven to move through the sliding block 4 to clamp the workpiece from two side positions, then the user loosens the locking nut 9, the connecting bolt 10 can move, then the connecting bolt 10 is pushed to move to drive the movable block 7 to move, the movable block 7 is moved to drive the limiting column 8 to move, the limiting column 8 is used for limiting the workpiece from the positions of the top and the bottom, so that the workpiece is stable, and the workpiece is not easy to drop.
