[0024] Working principle: In this embodiment, the slide 2 and the sliding shaft slide and switch. When the slide 2 is fixed, the sliding shaft can move, and when the sliding shaft is fixed, the slide 2 moves. An electromagnetic coil is provided inside the slide 2, and a permanent magnet is provided inside the permanent magnet shaft 5. The control box 3 is used to control the magnitude and direction of the current. Under the interaction between the electromagnetic coil and the permanent magnet, relative movement can be achieved between the slide 2 and the sliding shaft, and precise control of speed, position and acceleration can be performed.

[0025] Specifically, when the slide shaft moves, a mounting seat 6 is provided at the end of the slide shaft, and the operator can position and install the required actuator on the mounting seat 6 according to actual needs. Similarly, when the slide 2 moves, a mounting seat 2 7 is provided on the slide 2, and the operator can install the actuator on the mounting seat 2 7 according to actual needs.

[0026] When the slide 2 is fixed and the freedom of movement of the slide shaft is released, the fixed seat 8 is located on the support seat 9, and the slide 12 is pushed by the push wheel 14, that is, the push wheel 14 moves on the inclined surface on the vertical end of the slide 12, so that the matching rod 11 is matched with the matching hole 801 to achieve the fixation of the slide 2. At the same time, the positioning shaft 18 and the mounting seat 6 are released from the matching relationship. At this time, the state is that the slide 2 is fixed and the slide shaft moves as the moving end.

[0027] When the slide 2 is needed as the moving end, the lifting frame 15 works and the control wheel 16 rotates to adjust the position of the adjusting frame 13. The positioning shaft 18 first cooperates with the bottom of the mounting seat 6, and the push wheel 14 moves away from the inclined surface on the vertical end of the slide 12. The matching rod 11 moves and releases the fixed state with the matching hole 801; the adjusting frame 13 continues to move to lift the slide shaft and the slide 2. When it is at the preset height, the control wheel 16 pushes the pushing part 23 to move the rack 24, that is, the connecting gear 20 rotates, and under the connection of the transmission belt 17, the fixed turntable 19 rotates. Under the action of the connecting rod 21, the shaft seat 22 moves to fix the positioning shaft 18 and the mounting seat 6. At this time, the state is that both ends of the slide shaft are fixed, and the slide 2 is the moving end and can move.
