[0034] The shock absorbing component also includes a plurality of groups of shock absorbers 15 connected to the inner wall above the shock absorbing base 2. The plurality of groups of shock absorbers 15 are distributed in a circular array on the inner wall of the shock absorbing base 2, and each group of shock absorbers 15 is provided with an arc-shaped side plate 16 at one end close to the electric actuator body 3, and the inner side surface of each group of arc-shaped side plates 16 is in contact with the outer wall of the electric actuator body 3; the shock absorber 15 is composed of a telescopic connecting rod and a spring sleeved on the outside, and each group of arc-shaped side plates 16 is in contact with the outer wall of the electric actuator body 3. Through the elasticity of the plurality of groups of shock absorbers 15, the impact force from the horizontal direction on the electric actuator body 3 is reduced from all directions, and the shock absorbing effect of the electric actuator body 3 in the shock absorbing base 2 is good.

[0035] The limiting mechanism includes an arc-shaped friction block 23, which is fixedly connected to the left inner wall of the fixed box 6, and the arc surface of the arc-shaped friction block 23 is in contact with the outer wall of the driving rod 10.

[0036] The arc-shaped friction block 23 and the movable friction block 27 are both arc-shaped surfaces close to the driving rod 10. The operating rod 24 is fixedly connected to the slide plate 26 and the movable friction block 27. When the hand wheel 7 rotates to drive the driving rod 10 and the driving gear 11 to rotate, the operating rod 24 is pulled outward to drive the slide plate 26 to move outward. At this time, the connecting spring 25 is in a compressed state, and the movable friction block 27 is away from the outer wall of the driving rod 10. The friction between the arc-shaped friction block 23 and the driving rod 10 is small, and the driving rod 10 can drive the driving gear 11 to rotate smoothly, and the use direction of the electric actuator body 3 can be adjusted. After determining the use direction of the electric actuator body 3, release the operating rod 24, and the compressed connecting spring 25 can automatically return to its position, that is, drive the movable friction block 27 to move toward one end of the outer wall of the driving rod 10 and fit with the outer wall of the driving rod 10. At this time, the friction of the driving rod 10 is large and it no longer rotates. The electric actuator body 3 no longer swings after determining the use direction, thereby improving the stability of the electric actuator when in use.

[0038] Embodiment 2:

[0039] Reference Figure 1 and Figure 5 This embodiment is different from the first embodiment in that: mounting holes 4 are provided at the four corners of the base plate 1, a pull ring is installed at the end of the operating rod 24 away from the moving friction block 27, and the hand-held end of the pull ring is covered with an anti-skid rubber sleeve; the four groups of mounting holes 4 cooperate with external bolts to quickly fix it in the use position, the pull ring facilitates the pulling of the operating rod 24, and the anti-skid rubber sleeve plays an anti-skid role to prevent the hand from slipping when holding the pull ring.

[0040] Working principle: before using the present invention, first, put the electric actuator body 3 into the inner cavity of the shock absorbing base 2 from the opening at the top of the shock absorbing base 2, so that its bottom is attached to the bearing circular plate 14. Through the lateral sliding of the sliding member 30 on the cross bar 29, the elasticity of the compression spring 31 and the hinged supporting diagonal rod 33, a certain buffering force can be provided to the electric actuator body 3 on the bearing circular plate 14. With the elasticity of the two sets of telescopic rods 19, the damping spring 20 and the elasticity of the elastic ball 22, the impact force on the electric actuator body 3 from the vertical direction is reduced. Through the elasticity of multiple sets of shock absorbers 15, the impact force on the electric actuator body 3 from the horizontal direction is reduced from all directions. The shock absorbing effect of the electric actuator body 3 is good, and the electric actuator is not easily damaged during use or transportation.

[0041] By rotating the hand wheel 7, the driving gear 11 fixedly connected to the outer wall of the driving rod 10 can be driven to rotate. Since the driving gear 11 is meshed and connected with the driven gear plate 12, the bottom of the driven gear plate 12 is rotatably connected to the bottom plate 1 through the supporting shaft 13. The rotation of the driven gear plate 12 can drive the electric actuator body 3 in the shock absorbing base 2 to rotate and adjust the direction. The use direction can be changed according to needs, which is convenient for connecting the flange 9 with pipelines in different directions;

[0042] When the hand wheel 7 rotates to drive the driving rod 10 and the active gear 11 to rotate, the operating rod 24 is pulled outward to drive the slide plate 26 to move outward. At this time, the connecting spring 25 is in a compressed state, and the mobile friction block 27 is away from the outer wall of the driving rod 10. The friction between the arc-shaped friction block 23 and the driving rod 10 is small, and the driving rod 10 can drive the active gear 11 to rotate smoothly, and the use direction of the electric actuator body 3 can be adjusted. After determining the use direction of the electric actuator body 3, release the operating rod 24, and the compressed connecting spring 25 can automatically return to its position, that is, drive the mobile friction block 27 to move toward one end of the outer wall of the driving rod 10 and fit the outer wall of the driving rod 10. At this time, the friction of the driving rod 10 is large and it no longer rotates. The electric actuator body 3 no longer swings after the use direction is determined, thereby improving the stability of the electric actuator when in use.
