The support pad 8, the stud bolt 9 and the push rod 11 are arranged in parallel to form a group, and there are multiple groups in total. A pressure plate 12 is installed on the top of each group of stud bolts 9 and push rod 11, and the pressure plate 12 is arranged above the support pad 8. A workpiece placement groove is provided on the side wall of the positioning plate 2, and a product 16 is placed inside the workpiece placement groove. A plurality of installation grooves are distributed in a circular row on the back side of the positioning plate 2 and located on the periphery of the workpiece placement groove, and elastic fastening members 15 are installed inside the installation grooves.

[0023] A waist hole is provided on the surface of the pressure plate 12, and the stud bolt 9 is installed inside the waist hole. A first spring 10 is provided on the surface of the stud bolt 9. The first spring 10 is provided to improve the squeezing and fixing effect of the pressure plate. An end of the stud bolt 9 extending out of the waist hole is threadedly installed with an M16 shoulder nut 13. A docking groove for clamping the top of the push rod 11 is provided on the surface of the pressure plate 12. The pressure plate 12 can be moved and adjusted relative to the stud bolt 9 and the push rod 11.

[0024] The elastic support 14 includes a sleeve 141 fixed on the front side of the positioning plate 2, a top portion of the sleeve 141 is provided with a top head 144, a bottom portion of the sleeve 141 is provided with a screw plug 142, a second spring 143 is provided inside the sleeve 141 and between the top head 144 and the screw plug 142, the second spring 143 is provided to assist the top head 144 in resetting, and a fixing stud 145 is threadedly installed on the side wall of the screw plug 142.

[0025] The fixing stud 145 extends into the shaft sleeve 141 and contacts the bottom of the top head 144 . The surface of the top head 144 is beveled, and the chamfered position contacts the fixing stud 145 .

[0026] The elastic clamping member 15 includes a clamping fixing block 151 fixed inside the mounting groove, and a handle rod 155 is symmetrically fixed to the side wall of the clamping fixing block 151, and a support rod 152 is movably installed inside the clamping fixing block 151, and a clamping handle 156 is fixed to one end of the support rod 152 located on the same side of the handle rod 155, and a third spring 153 is mounted on the surface of one end of the support rod 152 away from the clamping handle 156. The third spring 153 is set to press the support rod 152, and a clamping stud 154 is threadedly installed on the side wall of the clamping fixing block 151, and the clamping stud 154 extends into the interior of the clamping fixing block 151 and contacts the support rod 152.

[0027] The end of the handle rod 155 away from the tightening and fixing block 151 is rounded to facilitate docking with the docking groove. Docking grooves are provided on the surface of the tightening handle 156 and on both sides of the support rod 152, and the docking grooves are respectively docked with the handle rod 155. The support rod 152 and the tightening and fixing block 151 are movably installed.
