摘要：The front end of a handgrip mounts an interchangeable tool- holder for pincertype tools whose opening and closing is controlled pneumatically through a cylinder-piston assembly to which a source of compressed air is supplied. Downstream of thecompressed-air source there is a pneumatic circuit for the automatic operation,intermittently at adjustable intervals, of the cylinder-piston assembly. The placing inservice and the taking out of service of the pneumatic circuit is controlled by simplyobturating and freeing, respectively, an aperture provided in the handgrip and
communicating with a bypass duct in parallel with the duct that supplies the compressedair to the cylinder-piston assembly.
