[0021] When the motor shaft presses down the contact plate 15, it can simultaneously drive the second piston rod 14 downward, push the gas in the inner cavity of the gas cylinder 13 to the inside of the gas groove 9 through the connecting groove 16, and then smoothly drive the two first piston rods 10 and the locking block 11 to move towards each other, and finally release the fixation of the first arc-shaped support block 5, the second arc-shaped support block 6 or the third arc-shaped support block 7 according to needs.

[0022] like Figure 3 As shown, the diameter of the first spring 12 is the same as the inner diameter of the air groove 9 .

[0023] By adopting the above scheme, a first spring 12 is provided. Due to the elastic force of the first spring 12, the first piston rod 10 and the locking block 11 can be pushed to move away from each other, so that the outer ends of the locking block 11 are respectively clamped in the second arc-shaped support block 6, the third arc-shaped support block 7 and the supporting plate 4, thereby realizing the clamping and fixing of the first arc-shaped support block 5, the second arc-shaped support block 6 and the third arc-shaped support block 7.

[0025] The top of the contact plate 15 is made of rubber.

[0026] By adopting the above solution, a contact plate 15 is provided. When the motor shaft fits against the contact plate 15, the contact plate 15 can be deformed to adapt to the surface of the motor shaft. Then, when the contact plate 15 is pressed down, the second piston rod 14 will push the gas in the inner cavity of the air cylinder 13 to discharge.

[0027] like Figure 3 As shown, the inner cavities of the first arc-shaped bracket block 5 , the second arc-shaped bracket block 6 and the third arc-shaped bracket block 7 are provided with a connecting groove 16 located between the bottom end of the air cylinder 13 and the bottom end of the outer side of the air groove 9 .

[0028] By adopting the above scheme, by providing a connecting groove 16, when the second piston rod 14 presses down the air cylinder 13, the gas at the bottom of the inner cavity of the air cylinder 13 can be pushed to the outer end inner cavity of the air groove 9 through the connecting groove 16, which can increase the air pressure and drive the two first piston rods 10 and the locking block 11 to move toward each other.

[0029] like Figure 4 and Figure 5 As shown, the rectangular slider 8 is fixedly installed with a limit block 17 at the front and rear, and the second arc-shaped support block 6, the third arc-shaped support block 7 and the placement plate 3 are fixedly installed with a limit column 18 located on the surface of the limit block 17.

[0030] By adopting the above scheme, by setting a limiting column 18, when the rectangular slider 8 is driven up and down as a whole, the limiting block 17 can slide vertically along the surface of the limiting column 18, thereby limiting the up and down movement of the first arc-shaped support block 5, the second arc-shaped support block 6 and the third arc-shaped support block 7.

[0031] like Figure 4 and Figure 5 As shown, a second spring 19 located on the surface of the limiting column 18 is fixedly installed at the bottom end of the limiting block 17, and the other end of the second spring 19 is fixedly connected to the second arc-shaped supporting block 6, the third arc-shaped supporting block 7 and the inner wall of the placement plate 3.

[0032] By adopting the above solution, by providing the second spring 19, due to the elastic force of the second spring 19, the limit block 17 can be pushed to drive the rectangular slider 8 and the first arc-shaped support block 5, the second arc-shaped support block 6 or the third arc-shaped support block 7 to reset upward as a whole.

[0033] The working principle and use process of this utility model:

[0034] First, when the manipulator places the motor shaft on the top of the two supporting plates 4, the contact plate 15 and the second piston rod 14 on the top of the first arc-shaped support block 5, the second arc-shaped support block 6 or the third arc-shaped support block 7 can be moved downward according to the diameter of the motor shaft, and then the inner cavity gas of the two gas cylinders 13 can be introduced into the inner cavity of the outer end of the gas groove 9 through the connecting groove 16 to increase the inner cavity air pressure, thereby smoothly driving the two first piston rods 10 and the locking block 11 to move toward each other, so that the locking block 11 is separated from the second arc-shaped support block 6, the third arc-shaped support block 7 or the inner wall of the supporting plate 4 to release the fixing effect of the first arc-shaped support block 5, the second arc-shaped support block 6 or the third arc-shaped support block 7.

[0035] Then, the motor shaft of the corresponding diameter size can press down the first arc-shaped support block 5, the second arc-shaped support block 6 or the third arc-shaped support block 7 to realize the switching of multiple diameter sizes. When the conveyor belt 2 drives the placement plate 3 and the support plate 4 and the motor shaft to one side, the pressure on the first arc-shaped support block 5, the second arc-shaped support block 6 or the third arc-shaped support block 7 can be released by another robot clamping, so that the elastic force of the second spring 19 is released to drive it to reset upward for subsequent switching of support.
