The connecting rod 531 is connected to the driving assembly 51, the driving assembly 51 drives the connecting rod 531 to move back and forth along the extending direction of the connecting rod 531, so that the sliding track 532 and the sliding block 533 move relatively, and the sliding track 532 or the sliding block 533 drives the first rotating member 52 to rotate relative to the supporting frame.

For convenience of description, the present embodiment is explained by taking the connection of the sliding rail 532 and the first rotating member 52 as an example, as shown in fig. 3, corresponding through holes are provided on the bottom of the connecting rod 531 and the sliding block 533, and the through holes are used for installing pins, so that the connecting rod 531 and the sliding block 533 are hinged. When the driving assembly 51 drives the connecting rod 531 to move up and down along the vertical direction, the sliding block 533 moves up and down, and meanwhile, the sliding block 533 rotates relative to the pin shaft and moves relative to the sliding rail 532, so that the first rotating element 52 is driven to rotate relative to the supporting frame.

The second rotating member 511 is connected with the support frame through a bearing seat, the second rotating member 511 is partially positioned outside the support frame, and the second rotating member 511 can rotate around the axis of the screw rod, but the position of the second rotating member 511 relative to the support frame cannot be changed. Thus, when the second rotary member 511 rotates, the screw rod is moved in the axial direction of the second rotary member 511 by screw transmission.

The second rotating member 511 includes a first rotating wheel 5111 and a rotating wheel sleeve 5112, the first rotating wheel 5111 is coaxially connected with the rotating wheel sleeve 5112, and an installation hole is formed in the inner side wall of the rotating wheel sleeve 5112.

It can be understood that the first rotary wheel 5111 and the rotary wheel sleeve 5112 are relatively fixed, and the screw rod can move along the axial direction of the second rotary member 511 by manually rotating the first rotary wheel 5111, so that the whole structure is simple, and the installation and adjustment are convenient. Wherein, the second rotating member 511 is partially positioned outside the supporting frame, which facilitates manual operation.

In this embodiment, the driving assembly 51 further includes a rotary driving member 512 and a second wheel 513, a housing of the rotary driving member 512 is connected to the supporting frame, a driving shaft of the rotary driving member 512 is connected to the second wheel 513 to drive the second wheel 513 to rotate, and the second wheel 513 drives the first wheel 5111 or the wheel sleeve 5112 to rotate.

The second rotating wheel 513 and the first rotating wheel 5111 are belt wheels, the second rotating wheel 513 is connected with the first rotating wheel 5111 through a synchronous belt, the servo motor drives the second rotating wheel 513 to rotate, the second rotating wheel 513 drives the first rotating wheel 5111 to rotate through the synchronous belt, the screw rod moves up and down along the vertical direction, and therefore the first rotating piece 52 is driven to rotate relative to the supporting frame. Or, the second rotating wheel 513 and the rotating wheel sleeve 5112 are belt wheels, the second rotating wheel 513 is connected with the rotating wheel sleeve 5112 through a synchronous belt, the servo motor drives the second rotating wheel 513 to rotate, the second rotating wheel 513 drives the rotating wheel sleeve 5112 to rotate through the synchronous belt, so that the screw rod moves up and down along the vertical direction, and the first rotating member 52 is driven to rotate relative to the support frame.

It can be understood that the transmission ratio is stable by means of gear transmission or synchronous belt transmission, so that the moving distance of the screw can be obtained by the rotating angle of the servo motor and the screw pitch of the screw. Knowing the distance of movement of the screw and the distance of the screw from the location where the first rotating member 52 is attached to the support bracket, the angle of rotation of the first rotating member 52 relative to the support bracket can be accurately calculated.

The end of the connecting rod 531 is connected to a mover seat of the linear motor, and the connecting rod 531 is driven to move by the linear motion of the mover seat. The connecting rod 531 may be driven to move by a linear motion of the piston rod by using an electric push rod or a piston rod of an air cylinder as the connecting rod 531 or by connecting the connecting rod 531 to the piston rod.

It can be understood that the angle of the first rotating member 52 rotating relative to the support frame can be accurately obtained through calculation by the linear displacement of the linear driving member and the distance from the connecting rod 531 to the position where the first rotating member 52 is connected to the support frame. The mode has simple structure and is convenient to control.
