摘要： A handle device for a hammer gun includes a tubular sleeve and a handle body. The tubular sleeve is adapted to connect threadedly with a barrel of the hammer gun, and includes front and rear end faces, a peripheral wall interconnecting the front and rear end faces, an installing cavity extending from the front end face toward the rear end face and adapted to receive therein the barrel of the hammer gun, and a retaining portion provided on the peripheral wall. The handle body has a grip portion, and a casing portion molded directly over the tubular sleeve and engaging the retaining portion so that the tubular sleeve is connected immovably to the handle body.

摘要： A pneumatic hammer drill includes a handle body, a pneumatic cylinder, a piston, and a shock-absorbing sleeve. The pneumatic cylinder has a cylinder rear end fitted in the handle body, a front tool-connecting end, and a pressure chamber. The piston is disposed slidably in the pressure chamber. A tool is inserted into the pressure chamber through the front tool-connecting end. A spring element is attached to the front tool-connecting end, and has a spring end connected to the tool for pulling the same rearwardly. The shock-absorbing sleeve is made of a resilient material, is inserted into the front tool-connecting end around the tool, and has a front end to abut against the tool when the tool is pulled rearwardly.

摘要： A pneumatic hammer drill includes: a pneumatic cylinder having a cylinder rear end fitted in a handle body, an air passage, and a pressure chamber; and an air valve adjacent to the cylinder rear end. The air valve has a front bearing end, a valve orifice interconnecting fluidly the air passage and the pressure chamber, and an opening disposed at the front bearing end in communication with the valve orifice. A piston is disposed slidably in the pressure chamber, and has a piston rear end capable of moving towards or away from the front bearing end. An air trap arrangement is associated with the piston rear end and the front bearing end to trap air between the same and around the opening so as to provide a shock-absorbing air cushion when the piston rear end moves towards the front bearing end.
