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

A device for carrying out operations on electronic components, comprising a handgrip, a tool-holder mounted on said handgrip, said tool-holder being adapted for holding pincer type tools having a pair of limbs, a cylinder-piston assembly mounted in said handgrip and operated by a source of compressed air, a rod mounted in said handgrip and operatively associated with said assembly and having a conical head provided to come into contact with a pair of levers connected to said limbs so as to occasion their closing and their subsequent re-opening with the return to the original position of said conical head, said device being characterized by the fact that, in parallel with the supply of compressed air to said cylinder-piston assembly, it is provided with a bypass duct that communicates, in the region of the handgrip of the tool, with an aperture communicating freely with the outside, said limbs being alternately closed and opened when said aperture is obstructed.
