When the pull rod 208 drives the B spring 209 to extend and retract, the B spring 209 drives the convex head 210 to extend and retract, and the B chuck 301 and the A chuck 207 are closed, and at this time the mushroom head 302 squeezes the convex head 210 to engage;

[0025] During installation, since the A chuck 207 is provided with a small hole adapted to the mushroom head 302, the B chuck 301 is closed with the A chuck 207, and the bottom of the roller 201 can fit with the polygonal nail 303. At this time, the mushroom head 302 squeezes the protruding head 210, and the protruding head 210 squeezes the B spring 209 to rebound and engage, thereby making it easier and faster to install the actuator 101, reducing the installation time and improving work efficiency; when disassembling the valve actuator 101, while pulling the pull rod 208 to drive the B spring 209 to expand and contract, the B spring 209 drives the protruding head 210 to expand and contract, thereby making it faster to disassemble the actuator 101 and improving the disassembly efficiency.

[0026] When the valve mechanism 3 is opened, the actuator 101 is started, and the actuator 101 drives the roller 201 to rotate, and the bottom of the roller 201 can fit with the polygonal nail 303. At this time, the rotation of the roller 201 drives the polygonal nail 303 to rotate at the same time, so that the valve mechanism 3 is opened and closed quickly, saving labor costs;

[0027] In addition, when the actuator 101 drives the roller 201 to rotate, the bearing seat 202 drives the iron plate 203 to move downward along the roller 201. At this time, the iron plate 203 drives the support leg 204 to move downward through the fixing box 206. When the polygonal nail 303 is fully opened, the bottom of the support leg 204 is inserted into the ground. The greater the downward movement of the polygonal nail 303, the deeper the support leg 204 is inserted into the ground, thereby supporting the actuator 101, reducing the pressure on the steel pipe, reducing the occurrence of safety accidents, and making the actuator 101 more stable.

[0028] When the valve mechanism 3 is opened, the iron plate 203 moves downward, driving the A spring 205 to move downward. The A spring 205 moves downward, and the support leg 204 moves downward on the fixing box 206. The more the iron plate 203 moves downward, the more the A spring 205 is squeezed. At this time, the groove of the fixing box 206 is more tightly engaged with the pull rod 208, thereby better reinforcing the pull rod 208 and increasing stability.

[0029] Working principle: When installing, close the B chuck 301 and the A chuck 207, at which time the mushroom head 302 squeezes the convex head 210, and the convex head 210 squeezes the B spring 209 to rebound and engage, and the installation is completed. When disassembling, pull the pull rod 208 to drive the B spring 209 to expand and contract, and the B spring 209 drives the convex head 210 to expand and contract, thereby completing the disassembly; when working, start the actuator 101, the actuator 101 drives the roller 201 to rotate, and the rotation of the roller 201 drives the polygonal nail 303 to rotate at the same time, and the actuator 101 drives When the movable roller 201 rotates, the bearing seat 202 clamps the iron plate 203 and moves downward on the roller 201. At this time, the iron plate 203 drives the support leg 204 to pass through the fixed box 206 and move downward. When the polygonal nail 303 is fully opened, the bottom of the support leg 204 is supported on the ground. At the same time, the iron plate 203 moves downward, driving the A spring 205 downward. When the A spring 205 moves downward, the support leg 204 moves downward on the fixed box 206. At this time, the groove of the fixed box 206 engages with the pull rod 208.
