The rotary base 1 includes a fixed base 11 and a rotary base 12 rotatable relative to the fixed base 11 about a rotation axis a parallel to a first direction D1, the rotary base 12 can be driven by a servo motor (not shown), for example. In the present embodiment, the base 2 has a first plate 21 disposed on the rotation base 12, and a second plate 22 perpendicular to the first plate 21 and extending along the first direction D1.

Referring to fig. 2 to 6, a plurality of driving cylinders 3 are disposed on the base 2 in a first direction D1 (the length direction of the base 2), the driving cylinders 3 include a cylinder body 31 disposed on the second plate 22 of the base 2, and a driving rod 32 extending along a second direction D2 perpendicular to the first direction D1 and capable of extending and retracting and rotating relative to the cylinder body 31, that is, the axis of the driving rod 32 of the driving cylinder 3 is parallel to the second direction D2. Specifically, the cylinder 31 of the driving cylinder 3 is formed with a rotation air chamber 311 and a telescopic air chamber 312 which are arranged in the second direction D2, wherein the rotation air chamber 311 is farther from the second plate 22 of the base 2, and the telescopic air chamber 312 is closer to the second plate 22 of the base 2. The driving rod 32 of the driving cylinder 3 includes a rotating rod 321, and a telescopic rod 322 slidably disposed on the rotating rod 321 along a second direction D2 (a direction in which an axis (not shown) of the driving rod 32 extends) and extending out of the cylinder 31, in this embodiment, the telescopic rod 322 penetrates through the through hole 221 of the second plate 22 of the base 2. The rotary rod 321 corresponds to the rotary air chamber 311, the telescopic rod 322 corresponds to the telescopic air chamber 312, the rotary rod 321 has a connecting column portion 3211 with a non-circular cross section, the telescopic cylinder 31 has a connecting groove portion 3221 with a non-circular cross section corresponding to the cross section of the connecting column portion 3211, and the connecting column portion 3211 of the rotary rod 321 is slidably but non-rotatably inserted into the connecting groove portion 3221 of the telescopic cylinder 31 in the second direction D2.

The driving cylinder 3 further includes a rotating piston 33 disposed on the rotating rod 321 and slidably received in the rotating air chamber 311 along the second direction D2, a telescopic piston 34 disposed on the telescopic rod 322 and slidably received in the telescopic air chamber 312 along the second direction D2, and a rotating unit 35 disposed between the rotating rod 321 and the cylinder 31. In the present embodiment, the rotation unit 35 includes a screw guide groove 351 formed on a surface of the rotation rod body 321, and a rotation guide pin 352 provided to the cylinder 31, the rotation guide pin 352 having a rotation guide protrusion 3521 for protruding into the screw guide groove 351. When the rotary rod 321 is moved by the rotary piston 33 to slide in the second direction D2 by the engagement of the screw guide groove 351 of the rotary unit 35 and the rotation guide protrusion 3521 of the rotation guide pin 352, the rotary rod can be synchronously rotated about the axis of the drive rod 32 by the sliding movement.

When the gas pushes the rotary piston 33 and the rotary rod 321 in the second direction D2 (the direction in which the axis of the drive lever 32 extends) in the rotary chamber 311, the sliding amount can be converted into the rotational amount rotating around the axis of the drive lever 32 by the rotating means 35. Moreover, since the rotating rod 321 and the telescopic rod 322 are connected to each other in a relatively slidable but non-rotatable manner, when the rotating rod 321 slides along the second direction D2, the telescopic rod 322 is not driven to slide along with the rotating rod 321, but only the telescopic rod 322 is driven to rotate around the axis of the driving rod 32, so that the driving rod 32 rotates relative to the cylinder 31. When the gas pushes the telescopic piston 34 and the telescopic rod 322 in the second direction D2 in the telescopic gas chamber 312, the drive rod 32 (the portion of the telescopic rod 322 extending out of the cylinder 31) can be made to expand and contract with respect to the cylinder 31. That is, by controlling the amount of gas entering and exiting the rotary air chamber 311 and the telescopic air chamber 312, the amount of rotation and the amount of expansion and contraction of the drive lever 32 can be controlled.
