The clamp is provided with two rotatable rotating blocks, each rotating block is provided with a first clamping part and a second clamping part which are perpendicular to each other, the two clamping parts can be seen as the groove bottoms, the two clamping parts can be seen as the groove walls on two sides, a combined groove is formed in such a way and used for clamping the plate, after the square plate is placed into the combined groove, the plate and the two rotating blocks are restricted with each other, the first clamping part and the second clamping part are abutted against the plate to enable the rotating blocks to rotate, the first clamping part and the second clamping part on the rotating blocks which cannot rotate after the plate is clamped can clamp the plate to enable the plate to move, then the upper end of the plate is abutted against by the abutting part, so that four outer side faces of the plate are clamped, and the clamp is very convenient to operate. And the distance between the two rotating blocks can be adjusted, so that the adjustable square workpiece support can adapt to square workpieces with more sizes after adjustment, and the adaptability is wide.

In the self-centering clamp, the end parts of the first clamping parts are respectively provided with a first bulge protruding upwards, and the side parts between the two second clamping parts are respectively provided with a second bulge protruding upwards.

The first bulge and the second bulge are designed to reduce the contact area between the side face of the steel plate and the first clamping part or the second clamping part, and the steel plate cannot be taken down due to the fact that the card with the large contact area is firm when the steel plate is taken down after machining is completed.

In the self-centering clamp, a spring is connected between the two rotating blocks.

The spring can guarantee that two turning blocks can not be crooked when not having the steel sheet installation, keeps certain angle, and further convenience we put into the steel sheet and carry out the centre gripping fixed.

In the self-centering fixture, the lower ends of the two rotating blocks are respectively provided with an installation part, and two ends of the spring are respectively fixed on one installation part.

In the above self-centering clamp, the pressing piece is of a columnar structure, threads are distributed on the outer peripheral surface of the pressing piece, the base plate is fixed with the mounting seat, and the pressing piece and the mounting seat are in threaded connection and can move towards the direction of the combined groove through the rotation of the threads.

In the above self-centering clamp, a rotating wheel is fixed at the upper end of the pressing piece.

Compared with the prior art, the product has the advantages that: this anchor clamps can regard two clamping parts as the tank bottom once, regard two clamping parts two as both sides cell wall, it is used for the card to establish panel to form the combination groove like this, put into such combination inslot with square panel after, restrict each other between panel and two turning blocks, clamping part one and clamping part two all support and lean on making the turning block unable to rotate on the panel, clamping part one and clamping part two on it can the centre gripping steel sheet make it unable to remove after the card goes into the steel sheet, then support the upper end of pressing the steel sheet through the piece of support, just so all held four lateral surfaces of steel sheet, very convenient operation.
