[0020] Further, the middle part of the partition 3 is provided with an avoiding through hole 13 for the connecting rod to pass through.

[0021] Further, the end surfaces of the upper cylinder 1, the lower cylinder 2 and the partition 3 are respectively provided with locking holes 14 for the locking bolts to pass through.

[0022] Further, the side surface of the lower mounting groove 12 of the lower cylinder 2 is provided with an air outlet groove, which includes a communicating groove 15 and a guide-out groove 16, the communicating groove 15 communicates with the inner cavity of the lower cylinder 2, and the guide-out groove 16 communicates with the communicating groove 15.

[0023] Further, the inner parts of the upper cylinder 1 and the lower cylinder 2 are respectively provided with an upper piston and a lower piston, the upper piston and the lower piston are connected through a connecting rod, the connecting rod is installed on the side surface and the circumference of the upper piston and the lower piston, and the outer diameter of the connecting rod is smaller than the diameter of the avoiding through hole 13 on the partition 3.

[0024] Further, the upper end of the upper cylinder 1 and the lower end of the lower cylinder 2 are respectively connected through a flange plate, and the flange plate connected with the lower cylinder 2 is provided with an air outlet hole communicating with the guide-out groove 16.

[0025] The outer sides of the upper mounting groove 6 of the upper baffle mounting boss 4 and the lower mounting groove 12 of the lower baffle mounting boss 11 are respectively provided with baffle and spring mounting holes 17, and the upper baffle and the upper spring, and the lower baffle and the lower spring are respectively installed through the baffle and spring mounting holes 17.

[0026] In use, this invention involves placing an upper piston in the upper cylinder body 1 and a lower piston in the lower cylinder body 2. The upper and lower pistons are connected by a connecting rod, which is mounted on the circumference of the piston's side. The upper end of the connecting rod passes through the upper piston and connects to the output end of the actuator. An upper spring and an upper baffle are placed in the upper mounting groove 6 on the side of the upper cylinder body 1.
