摘要： An apparatus for clamping fabric or apparel such as trousers comprises a stationary support member vertically mounted on a wheeled platform, and an adjustable clamp member pivotally supported by the support member, the two members forming the jaws of a clamp. An outwardly extending cam formed on the adjustable clamp member extends toward the stationary support member to cooperate with an actuation rod for moving the clamp member. The rod is pivotally mounted on the support member to slidingly engage the surface of the cam. As the actuation rod is operated to slide downwardly along the cam surface, the adjustable clamp member rotates with respect to the stationary support member closing the jaws of the clamp. A pawl is formed on the actuation rod and positioned to engage a ratchet assembly mounted on the platform to lock the adjustable clamp member to hold the fabric or apparel. A foot operated release moves the ratchet out of engagement with the pawl to unlock the adjustable clamp member, thereby providing a positive release of the jaws of the clamp.
