摘要： An air-seal structure for pneumatic nailers includes a valve member movably engaged with the end cap of the nailer and a plurality of paths defined radially through a skirt portion of the valve member. The paths are in communication with air release passage defined in the end cap. A seal is mounted to the skirt portion of the valve member and closes the paths. The seal contacts an end of the cylinder when the trigger is not squeezed. The seal is sucked due to the difference of pressure so that it will not be loosened during movement of the valve member. A cushion member is connected to a disk member on the inside of the end cap so as to absorb shocks when the piston returns back to the ready position.

摘要： A power stapler includes a barrel with a cylinder received therein and a piston is movably received in the cylinder. An end cap is connected to the rear end of the barrel and a frame is movably engaged with the inside of the end cap. A seal part is engaged with an annular space in the outside of the frame and contacts the cylinder. A plurality of passages are defined through the frame and communicate with the annular space so that the seal part is securely positioned because the pressure in the passages is lower than the outside of the seal part. A fixed member is connected to the end cap and a pad is engaged with the fixed member. The pad has notches in the distal end thereof which contacts the piston so that air trapped between the pad and piston is released via the notches when the piston moves back to the original position after a shot.

摘要： An exhausted air dispensing device for a hydraulic power nailer includes a ring engaged with a flange extending from a recessed area defined in an end cap of the body of the nailer. The flange has a plurality of notches which communicate with a passage from which the exhausted air of the nailer flows. The flange has a plurality of blocks extending from the ring and located in alignment with the notches in the flange so that the speed of the exhausted air is reduced when the exhausted air blows against the blocks. A cover has an opening defined in a periphery of the cover which is rotatably engaged with the recessed area. A positioning pin biasedly extends from the end cap and the cover has a plurality of dents in the bottom thereof so that the positioning pin is engaged with one of the dents of the cover.

摘要： A sealing assembly for an inlet valve of a power nailer includes a fixed frame and a movable member which has a tubular portion movably inserted through the central hole of the fixed frame and is biased by a spring. The movable member is connected to the cylinder so as to push the piston of the cylinder. The fixed frame has a flange with a tapered distal edge so that a seal is mounted to the flange and the seal has a tongue portion rested on the tapered distal edge. The tongue portion movably contacts the tubular portion. The movable member has a tapered distal edge on which a tongue portion of another seal is rested and movably contacts a flange of the fixed frame.

摘要： A safety device for a pneumatic stapler includes a safety member rotatably mounted to a barrel of the stapler by a torsion spring located between the safety member and the barrel. The safety member has a first protrusion and a second protrusion. The first protrusion is pushed by a magazine connected to the barrel and the second protrusion is located at a higher position to allow a safety plate to be moved between the two protrusions. When the magazine is removed and the second protrusion is rotated to a lower position, the safety plate is stopped by the second protrusion.

摘要： A human powered watercraft or land vehicle is described herein. A watercraft or land vehicle may have two pedals that reciprocated are in a linear or slightly curved trajectory but not a circular motion. As the two pedals are reciprocated, an output shaft is rotated in either a clockwise or counterclockwise direction when the left pedal is pushed forward or when the right pedal is pushed forward. The output shaft may be connected to a propeller of a watercraft or a land vehicle so as to propel the watercraft or land vehicle forward. The output shaft may receive rotational input through two gears mounted to the output shaft with one-way bearings that enable the output shaft to rotate in the same direction regardless of whether the left pedal or the right pedal is being pushed forward.
