[0006] As a preferred solution of the utility model, a front end cover is installed on the cylinder body, and the air inlet hole is also opened on the front end cover and extends toward the inside of the cylinder body.

[0007] To implement the above technical solution, the air inlet is provided to provide an air source for the cylinder body, thereby facilitating the control of the clamping jaws.

[0008] As a preferred solution of the utility model, the driving connecting member includes: a connecting rod and a piston rod movably connected to the connecting rod, and the connecting rod is connected to the clamping jaw head.

[0009] To implement the above technical solution, the connecting rod and the piston rod cooperate with each other to better control the clamping jaw head.

[0010] As a preferred solution of the utility model, an elastic member is installed at the connection between the piston rod and the front end cover, and a rear end cover is also installed at the connection between the connecting rod and the cylinder body.

[0011] By implementing the above technical solution, the front end cover and the rear end cover realize the installation of the cylinder body and improve the stability during the movement.

[0012] As a preferred solution of the utility model, a rotating shaft is installed at the clamping jaw head and the connecting rod.

[0013] To implement the above technical solution and the setting of the rotating shaft, the extension and clamping of the clamping claw head can be achieved.

[0014] In summary, the utility model has the following beneficial effects:

[0015] Through the cylindrical automatic clamp structure, the air pressure and piston movement are used to push the connecting rod to move, and the movement of the connecting rod will cause the clamp to close and clamp the product; after the air is cut off, the restoring force of the spring when compressed will cause the piston and the connecting rod to move down and return to their original position, at which time the clamp will be pulled and opened to release the product. The automatic closing and opening of the clamp is realized to clamp the product in the mold space, and the operation is relatively simple. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Example

[0023] A lightweight three-claw cylinder, such as Figure 1 to Figure 2 As shown, it includes: a cylinder body 1; an air inlet hole 2 opened on the cylinder body 1; a clamping jaw head 3 arranged on the cylinder body 1 away from the air inlet hole 2, and a driving connecting piece is provided on the clamping jaw head 3; and a cylinder body protection cover 4 located between the air inlet hole 2 and the clamping jaw head 3.

[0024] A front end cover 5 is installed on the cylinder body 1 , and an air inlet 2 is also provided on the front end cover 5 and extends toward the inside of the cylinder body 1 .

[0025] The front end cover 5 is installed with the cylinder body 1 so that the three-jaw cylinder forms a whole. Under the action of the driving connection part, the position of the clamping jaw head 3 is adjusted.

[0026] Specifically, the driving connection member includes: a connecting rod 6, a piston rod 7 movably connected to the connecting rod 6, the connecting rod 6 is connected to the clamping claw head 3, and the piston rod 7 drives the connecting rod 6 to move, so that the clamping claw head 3 clamps the product.

[0027] An elastic member 8 is installed at the connection between the piston rod 7 and the front end cover 5, and a rear end cover 9 is also installed at the connection between the connecting rod 6 and the cylinder body 1; after the air source is connected, the elastic member 8 is compressed and the piston rod 7 moves, so that the clamping claw head 3 is expanded and retracted.

[0028] Finally, a rotating shaft 10 is installed between the clamping jaw head 3 and the connecting rod 6 , and the rotating shaft 10 facilitates the movement of the clamping jaw head 3 .

[0029] When the air source is connected, the piston is pushed downward, causing the clamping jaw head 3 to move and open, thereby clamping the product.

[0030] Through the cylindrical automatic clamp structure, the air pressure and piston movement are used to push the connecting rod to move, and the movement of the connecting rod will cause the clamp to close and clamp the product; after the air is cut off, the restoring force of the spring when compressed will cause the piston and the connecting rod to move down and return to their original position, at which time the clamp will be pulled and opened to release the product.
