A spring 4 is arranged between the bottom plate 3 and the sliding mounting plate 21 of the sliding mechanism 2, and a limit bolt 5 is arranged between the bottom plate 3 and the sliding mounting plate 21. The spring 4 is used for damping, and since the size and weight of the steel plate are generally very large, the spring 4 is increased to improve the damping effect because the spring is easy to shake when being clamped by a plurality of clamps during the operation processes such as clamping, transporting and putting down. In addition, in order to prevent the bottom plate 3 and the slide mounting plate 21 from falling off, a limit bolt 5 is provided therebetween, and the limit bolt 5 can limit the maximum position of the interval therebetween.
The clamping mechanism 1 comprises a lower clamping plate 11, a telescopic mechanism 11, an inclined surface pushing block 13 and an upper clamping plate 14; the lower clamping plate 11 is mounted on the slide mechanism 2, and specifically may be mounted on a slide mounting plate 21 of the slide mechanism 2. The shrinkage mechanism 11 is connected with the inclined surface pushing block 13 to drive the inclined surface pushing block 13 to reciprocate. The front end of the upper clamping plate 14 is hinged with the lower clamping plate 11 to form a lever structure, the front end of the upper clamping plate 14 is provided with a mounting groove 15, an arc-shaped upper tooth block 16 is arranged in the mounting groove 15, and a lower tooth block 17 is arranged at a corresponding position of the lower clamping plate 11; the rear end of the upper clamping plate 14 is provided with a roller 18, and the roller 18 is contacted with the inclined surface pushing block 13.
When the telescopic mechanism 11 extends forwards, the inclined surface push block 13 is close to the roller 18 of the upper clamping plate 14, the roller 18 is pushed to be tilted upwards gradually, and when the inclined surface push block 13 moves forwards, one end of the upper clamping plate 14 is tilted upwards at a larger angle, so that the distance between the front end and the lower clamping plate 11 under the leverage is smaller, and clamping is formed.
In the preferred embodiment of the utility model, the clamping mechanism 1 further comprises a guide seat 19, the guide seat 19 is arranged at the rear end of the lower clamping plate 11, and a telescopic rod of the telescopic mechanism 11 penetrates through the guide seat 19 and is connected with the inclined surface pushing block 13; the telescopic mechanism 11 is a telescopic cylinder, and the telescopic cylinder is provided with a wiring housing which mainly serves to protect the circuit of the cylinder.
The utility model preferably has an accessory plate 120 at the rear end of the lower clamp plate 11, and a keyhole structure is provided on the accessory plate 120 for fixing the telescoping mechanism 11 to the accessory plate 120.

The utility model adopts the principle of lever to clamp, namely the clamping end moves downwards, and the other end rotates upwards to form clamping. However, since the movement of the two ends belongs to the rotation around the fulcrum, the contact point between the upper clamping plate 14 and the lower clamping plate 11 is point contact, the stress concentration damage to the steel plate is more easily caused by the point contact clamping, and the clamping stability is reduced, so that the arc-shaped upper tooth block 16 is arranged at the clamping point of the upper clamping plate 14, when the arc-shaped upper tooth block 16 contacts the plate, the arc-shaped upper tooth block 16 is firstly point contact, but after being stressed, the upper tooth block 16 can rotate in the mounting groove 15 by a certain angle, the rotating moment is derived from the interaction force between the steel plates, and the upper tooth block 16 and the steel plate are finally in surface contact, so that the self-adaptive clamping can be realized, the input moment required by clamping is reduced, and the better clamping stability can be realized.
