Abstract
A hand/pneumatics dual operation vacuum pulling device includes an elongate shank and a slidable backward ram fit to the shank. The shank has an end to which a suction cup is attached. The shank has an upper end to which a handgrip having a pressure relief seat is mounted. A ramp stop section is formed below the pressure relief seat. The handgrip can selectively and switchably couple with a hand-operating pump piston to form a hand-operating vacuum pulling device, or couple with a pneumatic operation seat to form a pneumatically-operating vacuum pulling device. For hand operation or pneumatics operation, the vacuum pulling device is allowed to easily switch between the two modes according to the availability of power supply and the site of use, thereby achieving an excellent device for one device having two ways of use.
