Cylinders are widely used in the drive of mechanisms and the clamping of workpieces. For the clamping and clamping of workpieces, special pneumatic grippers and clamping cylinders are generally used.

[0003] For example, Chinese patent application CN104723148B discloses a clamping device, including a base plate, a clamping unit, a driving unit, and an air control unit. The clamping unit includes: a motion mechanism, a support mechanism, and a pressure head mechanism. The driving unit includes: a first double-acting cylinder, having a first cylinder body provided with a first front port and a first rear port, and a first piston rod; a second double-acting cylinder, having a second cylinder body provided with a second front port and a second rear port, and a second piston rod; a first connecting member, having five degrees of freedom of X, Y, α, β, and γ; a second connecting member, having five degrees of freedom of X, Y, α, β, and γ.
