Patent ID: 6918523

Claim:
A nailer with improved spacer actuator design comprising: a nailer body with a pedestal board provided at an outlet of a bottom thereof; a spacer actuator comprised of a container tube and a flexible propelling unit, said container tube being hollowing and being used to superpose spacers, a bottom of the container tube being fastened securely to a preset pedestal board at a bottom, where a spacer at a base of said container tube move towards said outlet a liftable cover allowing a shaft axle to screw one side into a top of the container tube; wherein in the case of a closing state of the cover, the hollow trough connects to an open-top hollow tube of the container tube, enclosed surface being arranged at the top of the hollow trough while a L-shape guide trough is mounted at one side wall of the hollow trough; and wherein a wedge groove is placed at the end of L-shape guide trough, where a vertical guide trough is provided at one side wall of the container tube's hollow tube; and wherein, in the case of a closing state of the cover, the top end of the vertical guide trough connects to L-shape guide trough, and a fixation component is provided at another side of a cover to ensure fixation thereof; a propelling unit comprised of a propelling block, a spring and a control board, said propelling block being placed at the bottom of the hollow trough of the cover, the control board being provided at the inner side of the propelling block and the spring being mounted between the control board and inner wall of hollow trough to push down the propelling block flexibly; wherein an outer face of the control board is provided with a toggle switch that protrudes from L-shape guide trough; and wherein the toggle switch is screwed into the wedge groove of L-shape guide trough, the propelling block will be fixed to avert the spring into a compressing state; and wherein the toggle switch shifts out of the wedge groove of L-shape guide trough, the propelling block slides downwards along the hollow tube of the container tube and place the spring into an extending state, thereby pressing and superposing flexibly the spacers within the hollow tube.
