ABSTRACT:
A grip structure for a pressure-based tool has a main body, a grip, an operating rod, a flexible part, and a pressure block. The pressure block and operating rod are assembled in a groove of the main body. A bottom of the pressure block and a surface in the groove of the main body are set with an elastic supporter in between. A bottom of the pressure block is equipped with a groove so that a top of the elastic supporter contacts the bottom of the grip by passing through the groove. The grip is urged by the elastic supporter regardless of an upward or downward motion applied to the grip.
