[0019] Specifically, before the device clamps the aluminum substrate, according to the size of the aluminum substrate, the pressing block 813 is pressed down, and the pressing block 813 drives the connecting end of the elastic spring 814 to approach the rotating frame 804, so that the end of the elastic spring 814 away from the pressing block 813 is bent under the lever action of the elastic spring 814, and the sliding frame 817 is driven to overcome the elastic force of the second spring 816 and move in the direction away from the rotating frame 804, so that the sliding frame 817 drives the bevel gear ring 1 818 to release the bevel gear ring 2 819.

[0020] In specific application scenarios, the stepless adjustment module 8 is mainly suitable for the stepless adjustment link in the stepless adjustment process, that is, the stepless adjustment module 8 uses the curved groove 808 and the short shaft 807 to allow the movable rod 806 to slide more finely in the cutting groove 805, thereby accurately controlling the stability of the clamping wheel 5 when clamping the aluminum substrate, reducing the shaking of the aluminum substrate in the clamping wheel 5, and providing assistance for the mounting block 1 to accurately place the aluminum substrate on the spindle of the processing equipment.
[0021] It should be noted that the slide cylinder 10 and the spring 6 are used to improve the flexibility of the hand-held device; the sixty-degree inclined surface clamping wheel 5 is used to achieve accurate positioning of the product.
[0022] Reference Figure 6 and Figure 7In a preferred embodiment, a groove 901 is provided on one side of the three movable rods 806 close to the mounting block 1, and a boss 1 is provided on the outside of the groove 901 through bolt connection, and the outside of the boss 1 is connected to the inner wall of the groove 901 through bolt connection, and a square tube 902 is connected to the boss 1 through bolt connection, and an air bag 1 903 is connected to the inside of the square tube 902 through bolt connection, and an air bag 1 903 is connected to the side away from the contact plate 810 through bolt connection with an air guide tube 904 through bolt connection, and the outside of the air guide tube 904 is connected to a convex ... The air guide tubes 904 are provided with throat shrinkage tubes 905 on the outside, and the throat shrinkage tubes 905 are connected to the side opposite to the boss 2 by bolts; the ends of the three air guide tubes 904 away from the air bag 1 903 are connected to the air bag 2 906 by bolts, and the ends of the air bag 2 906 away from the air guide tube 904 are connected to the boss 3 by bolts, and the inner walls of the grooves 901 are provided with rectangular grooves 907, and the inner walls of the rectangular grooves 907 are slidably connected to the outside of the boss 3 on the same side, and the side of the boss 3 away from the air bag 2 906 is connected by bolts.

[0023] Specifically, when the clamping wheel 5 is about to approach the aluminum substrate, the sliding sleeve 12 on the clamping column 4 contacts the buffer block 910 in the accommodating groove 803. As the clamping column 4 continues to move, the insertion rod 911 is inserted into the square tube 902, so that the airbag 1 903 is compressed, and the gas in the airbag 1 903 is transported into the airbag 2 906 through the air duct 904.

When the clamping wheel 5 is about to approach the aluminum substrate, the sliding sleeve 12 on the clamping column 4 contacts the buffer block 910 in the accommodating groove 803. As the clamping column 4 continues to move, the insertion rod 911 is inserted into the square tube 902, so that the air bag 1 903 is compressed, and the gas in the air bag 1 903 is transported into the air bag 2 906 through the air guide tube 904. Under the action of the set throat shrinkage tube 905, the compressed air guide tube 904 changes the cross-sectional area, so that the flow rate of the gas in the air guide tube 904 is reduced, so that the gas in the air bag 1 903 flows into the air bag 2 906 more slowly, so that the clamping wheel 5 slowly scoops up and fixes the aluminum substrate.
