Since the force applied by the first spring 18 is less than the force applied by the second spring 19, the pressure plate 4 will drive the slider 7 to move along the dovetail groove 6 through the slide bar 9, so that the slider 7 clamps the workpiece. At this time, the wedge block 3 continues to move downward, and since the slider 7 clamps the workpiece, the slider 7 cannot move, and the pressure plate 4 will move downward at this time. The pressure plate 4 will push the connecting block 16 downward through the slide bar 9, and the connecting block 16 will stretch the second spring 19, so that the pressure plate 4 presses the workpiece, fixes the workpiece, and prevents the workpiece from moving.

[0023] The driving component has two first threaded rods 10, which are rotatably connected to the upper surfaces of the two tray bodies 5 respectively. The circumferential outer walls of the two first threaded rods 10 are threadedly connected to the connecting plates 1. Two wedge blocks 3 are welded to the bottom of the connecting plates 1, and the inclined surfaces of the wedge blocks 3 are in contact with the pressure plate 4. When the first threaded rods 10 are rotated, the connecting plates 1 will move downward through the threaded engagement between the first threaded rods 10 and the connecting plates 1, and the connecting plates 1 will drive the wedge blocks 3 to move downward, and the wedge blocks 3 will push the pressure plate 4 to move through their own inclined surfaces.

[0024] In the utility model, in order to make the connecting plate 1 move vertically, the upper surfaces of the two material tray bodies 5 are provided with guide components for making the connecting plate 1 move vertically, and the guide components are two positioning columns 2, and the two positioning columns 2 are respectively welded to the upper surfaces of the two material tray bodies 5, and the positioning columns 2 pass through the connecting plate 1, and the connecting plate 1 will move downward along the positioning columns 2, so that the connecting plate 1 can move vertically, and the connecting component includes two fixed plates 11, and the two fixed plates 11 are respectively arranged at the top and bottom of the joints of the two material tray bodies 5, and the top and bottom of the two material tray bodies 5 are provided with two card grooves 14, and a plurality of card blocks 15 are welded on the opposite sides of the two fixed plates 11, and the card blocks 15 are carded with the card grooves 14, and the bottom of the fixed plate 11 located at the top is rotatably connected with the second threaded rod 12, and the second threaded rod 12 passes through the fixed plate 11 located at the bottom and is connected to the fixed plate located at the bottom 11 is threadedly connected, and the block 15 on the fixing plate 11 is clamped with the clamping groove 14 on the material tray body 5, so that the material tray body 5 can be connected, and the second threaded rod 12 is rotated, and the second threaded rod 12 will drive the fixing plate 11 below to move downward, so that the clamping block 15 on the fixing plate 11 below is disengaged from the clamping groove 14, and the material tray body 5 can be separated at this time, which is convenient for assembling and disassembling the two material trays, and convenient for the staff to change the size of the material tray, and improves the use effect of the material tray.

[0025] Working principle: when it is needed, place the workpiece on the heat treatment tray, and then rotate the first threaded rod 10. The first threaded rod 10 will engage with the thread between the connecting plate 1 to make the connecting plate 1 move downward along the positioning column 2, and the connecting plate 1 will drive the wedge block 3 to move downward. At this time, since the force of the first spring 18 is less than the force of the second spring 19, the wedge block 3 will push the pressure plate 4 through its own inclined surface to drive the slider 7 to move along the dovetail groove 6 through the slide rod 9, so that the slider 7 clamps the workpiece. At this time, the wedge block 3 continues to move downward, and since the slider 7 clamps the workpiece, the slider 7 cannot move, and the pressure plate 4 will move downward at this time.
