A fluid pressure vise actuator includes a housing and an inner bore of the housing. A piston is disposed in the housing, and the piston is configured to actuate based on a pressure increase in ports of the housing. A gear is also disposed in the inner bore of the housing, and a portion of the gear is adjacent to the piston such that an actuation of the piston is configured to rotate the gear. The gear includes a socket configured to interface with a vise and operate the vise based on a rotation of the gear. The housing also includes adjustable clamping blocks configured to engage with the vise to provide support for the housing during operation. An adjustment of the clamping blocks enables the fluid pressure vise actuator to interface with multiple types of existing vises.

A releasable clamp 10 for holding an article 1000 or parts thereof is describe. The clamp 10 comprises: a set of jaws, including a first jaw 100A and a second jaw 100B, arrangeable to hold the article 1000 therebetween; a set of spacers, including a first spacer 200A, arrangeable to space apart respective jaws of the set of jaws; and a set of retaining members, including a first retaining member 300A, arrangeable to space together respective jaws of the set of jaws; wherein respective jaws of the set of jaws comprise a first region 110 for contacting the article 1000, an optional second region 120 defining a portion of a first part 410 of a coupling member 400, a third region 130 for contacting a respective spacer of the set of spacers and a fourth region 140 for contacting a respective retaining member of the set of retaining members. The clamp 10 is configurable in: a first configuration, wherein the first jaw 100A and the second jaw 100B are mutually unjoined; and a second configuration, wherein the first spacer 200A is arranged to space apart the first jaw 100A and the second jaw 100B and wherein the first retaining member 300A is arranged to apply a net compressive force on the first spacer 200A via the first jaw 100A and the second jaw 100B, whereby the first jaw 100A and the second jaw 100B are conjoined and thereby hold the article 1000 therebetween.
