[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] In order to facilitate the installation and disassembly of the actuator as a whole, refer to Figure 1 、 Figure 2 and Figure 3As shown, it includes an upper base 1, a lower base 2 and a cylinder 3. An independent area for placing the cylinder 3 is reserved between the upper base 1 and the lower base 2. The upper and lower sides of the cylinder 3 are respectively connected to the cylinder 3. A fixing rod 4 for connection is provided between the upper base 1 and the lower base 2. The outer sides of the upper base 1 and the lower base 2 are both provided with mounting columns 5. A limiting component is provided on the mounting columns 5. The head and tail ends of the cylinder 3 are respectively connected to the upper base 1 and the lower base 2 to complete the installation of the cylinder 3, and the bolts 14 are used to fix it. The rod 4 is locked so that the cylinder 3 is fixed in the independent area formed between the upper base 1 and the lower base 2. Then, the two limit plates 11 are pressed to squeeze the spring 10 through the limit plates 11. The spring 10 reacts on the movable block 9 to allow the movable block 9 to slide in the through hole 7. After the mounting column 5 is installed in the mounting hole preset by the external device, the spring 10 is deformed and reacts on the limit plates 11, so that the two limit plates 11 abut against the inner wall of the mounting hole, thereby completing the installation of the cylinder 3. The overall structure is simple and easy to use.

[0020] In order to facilitate the contact between the limiting plate 11 and the inner wall of the mounting hole to complete the fixation, refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the limit assembly includes notches 6 on both sides of the head of the mounting post 5, and a through hole 7 is provided on the inner wall of the notch 6. Both sides of the through hole 7 are provided with a slide groove 8 connected to the through hole 7. A movable block 9 is provided in the through hole 7, and the movable block 9 is connected to a spring 10 at one end facing the opening of the through hole 7. The spring 10 is connected to a limit plate 11 at one end away from the movable block 9. When the limit plate 11 is pressed, the limit plate 11 squeezes the spring 10, and the spring 10 squeezes the movable block 9. As the movable column 12 slides in the slide groove 8 along the length direction of the slide groove 8, the movable block 9 is driven to move in the through hole 7. When the movable block 9 moves to the end inside the through hole 7, it will abut against the inner wall of the through hole 7, thereby reversely squeezing the movable block 9, causing the spring 10 to deform and react on the limit plate 11, so that the limit plate 11 abuts against the inner wall of the mounting hole to complete the fixation. There are two limit plates 11, and the two limit plates 11 are arc-shaped on the side away from each other. After the two limit plates 11 fit against the inner wall of the notch 6 in the notch 6, they can form a circle that matches the mounting hole, making it easy to insert into the mounting hole. A movable column 12 is provided in the slide 8. The movable column 12 is connected to the movable block 9 at the end away from the slide 8. As the movable column 12 slides in the slide 8, the movable block 9 moves more smoothly, thereby improving the flexibility of the movable block 9. Grooves 13 are provided inwardly around the side away from each other of the upper base 1 and the lower base 2. Bolts 14 for locking the fixed rod 4 are provided in the grooves 13. After tightening the bolts 14, the fixed rod 4 is locked, so that the connection between the upper base 1 and the lower base 2 is fixed. The two limit plates 11 are symmetrically arranged.

[0021] When in use, first connect the head and tail ends of the cylinder 3 to the upper base 1 and the lower base 2 respectively to complete the installation of the cylinder 3, and use the bolt 14 to lock the fixing rod 4 so that the cylinder 3 is fixed in the independent area formed between the upper base 1 and the lower base 2, then press the two limit plates 11, and the spring 10 is squeezed through the limit plates 11. The spring 10 reacts to the movable block 9, allowing the movable block 9 to slide in the through hole 7. After the mounting column 5 is installed in the preset mounting hole of the external device, the spring 10 is deformed and reacts to the limit plates 11, so that the two limit plates 11 abut against the inner wall of the mounting hole, thereby completing the installation of the cylinder 3.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
