The working principle is as follows: the device is firstly installed at a use position and used by the following operation modes:

according to fig. 1-7, a workpiece of relatively large mass is placed in a recess in the upper surface of the processing platform 1, so that the workpiece is supported on the support plate 8;

the supporting plate 8 can move downwards through the self-gravity of the workpiece, the supporting rod 23 at the lower end of the supporting plate 8 gradually extends into the supporting tube 22, and the supporting tube 22 and the spring 9 outside the supporting rod 23 are compressed;

in the process that the support plate 8 moves downwards, the extrusion sleeve 16 drives the connecting rod 20 to synchronously move downwards, and further drives the support shell 15 to synchronously move downwards;

during the downward movement of the support housing 15, the connection ring 11 is moved downward, so that the self-resetting rotary cylinder 10 is rotated through the sliding connection between the guide block 18 and the guide groove 12;

when the self-resetting rotary cylinder 10 rotates, the screw rods 4 coaxially connected with the self-resetting rotary cylinder synchronously rotate;

when the screw rod 4 rotates, the 2 connecting blocks 5 on the screw rod are close to each other, so that the included angle of the control rod 7 connected with the 2 connecting blocks 5 is reduced, the clamping pieces 6 are gradually close to each other, and a workpiece with larger mass is stably clamped;

after the workpiece is machined, the control rod 7 can be pulled, so that the control rod 7 moves in the adjusting groove 2 and further drives the bolt 13 to rotate;

by the rotation of the bolt 13, the position of the bolt 13 and the support housing 15 can be changed, and the sliding rod 19 can be moved synchronously;

when the sliding rod 19 moves, the connecting rod 20 is driven to move synchronously, and the connecting rod 20 is connected with the guide groove 14 in a sliding manner, so that the connecting rod 20 gradually retracts towards the inside of the supporting shell 15, and the connecting rod 20 can be separated from the extrusion sleeve 16;
