The clamping plate 8 can be guided by the guiding grooves 10 and the guiding blocks 11, so as to prevent the clamping plate 8 from tilting.

[0029] During use, first place the workpiece between the two clamping plates 8. The bearing block 2 can support the workpiece. Then, drive the rotating shaft 1402 with the second motor 1401 of the adjusting assembly 14 to drive the gear 1403 to rotate. The gear 1403 can drive the two racks 12 to move synchronously, so as to centrally adjust the distance between the two clamping plates 8. The two clamping plates 8 can centrally clamp the workpiece, so as to quickly fix the workpiece. After the workpiece is fixed, the staff can process the workpiece through a horizontal machining center.

[0030] When it is necessary to adjust the height of the workpiece, the operator drives the bidirectional lead screw 602 through the first motor 601 of the driving assembly 6. The bidirectional lead screw 602 can convert the rotational motion into the linear motion of two threaded sleeves 603. Since the support arms 604 are installed in a hinged manner, when the two threaded sleeves 603 move, the inclination angles of the two support arms 604 can be adjusted synchronously, and then the synchronous lifting of the two support plates 5 can be controlled, so as to adjust the height of the bearing platform 2 and enable the two support plates 5 to be evenly stressed. During the adjustment process, the base 1 can guide the bearing platform 2 to prevent it from tilting.
