Wherein the locking nut 73 is fixedly connected with the support plate 71. The suspension screw 74 is configured to rotate the suspension screw 74, and the front end of the actuator 10 is driven to move by the first hanging ring 75, the elastic member 76 and the second hanging ring 77, so as to adjust the position of the front end of the actuator 10

When the position of the front end of the actuator 10 is adjusted, the position of the suspension screw 74 with respect to the support plate 71 may be adjusted, the length of the support column 72 may be adjusted, or the position of the suspension screw 74 with respect to the support plate 71 and the length of the support column 72 may be adjusted at the same time. Illustratively, when the front end of the actuator 10 needs to be raised, the suspension screw 74 may be rotated counterclockwise (or clockwise), so that the suspension screw 74 drives the front end of the actuator 10 to move through the first hanging ring 75, the elastic member 76 and the second hanging ring 77, and the length of the suspension screw 74 below the support plate 71 is gradually reduced, so that the front end of the actuator 10 gradually approaches the support plate 71, thereby achieving the purpose of raising the front end of the actuator 10. Alternatively, the support column 72 may be stretched to increase the length of the support column 72, thereby increasing the height of the support plate 71, and thus achieving the purpose of raising the front end of the actuator 10. Still alternatively, while increasing the length of the support post 72, the suspension screw 74 is rotated counterclockwise (or clockwise) so that the length of the suspension screw 74 located below the support plate 71 is gradually decreased and the height of the support plate 71 is increased, thereby achieving the purpose of raising the front end of the actuator 10.

The first hanging ring 75 and the second hanging ring 77 are provided so that the front end of the actuator 10 can be prevented from rotating along with the hanging screw 71 when the hanging screw 71 rotates. Alternatively, the elastic member 76 may be a spring, which is not limited in this embodiment.

Further, the structure of the support pillar 72 described above may have various cases, and the present embodiment provides the support pillar 72 having the following two structures.

In one instance, the support column 72 includes at least two columns 721, the at least two columns 721 are connected end to end, and each column 721 is capable of telescoping along its length to enable the length of the support column 72 to be varied. Since at least two of the pillars 721 can be connected end to end, the number of the pillars 721 required can be determined according to actual needs. Illustratively, when the front end of the actuator 10 needs to reach a high position, a plurality of the pillars 721 may be connected end to increase the height of the support plate 71; fewer legs 721 can be connected end to end when the desired position of the front end of the actuator 10 is low. Alternatively, in this case, the upright 721 may be a telescopic rod.

In another case, the support column 72 includes at least two columns 721, and each column 721 has a bolt shaft at one end and a threaded hole at the other end, and the bolt shaft of one column 721 can be screwed into the threaded hole of the other column 721 to connect the two columns 721 by screwing. Also, the length of the support post 72 can be adjusted by adjusting the degree to which the bolt shank is screwed into the threaded hole. When it is necessary to increase the length of the support column 72, the length of the bolt shaft of the other upright 721 can be reduced by connecting the threaded hole of the one upright 721 with the end of the bolt shaft of the other upright 721, thereby increasing the length of the entire support column 72.

The support column 72 with the two structures can flexibly adjust the length of the support column 72, and the adjustability and the practicability of the actuator fixing device are further improved.
