Nailer device
A nailer device has a housing containing a motor, a gear box, a transmission mechanism, and a striking rod. The motor, the gear box, and the transmission mechanism cooperate to cause the striking rod to be moved back and forth. The striking rod has a peripheral outer surface and a longitudinal axis and the striking rod and the gear box are connected through a sliding connection structure which allows the striking rod to be moved along its longitudinal axis and which prevents the striking rod from rotating around its longitudinal axis.
1. A nailer device, comprising:
a housing containing a motor, a gear box, a transmission mechanism, and a striking rod wherein the motor, the gear box, and the transmission mechanism cooperate to cause the striking rod to be moved back and forth; wherein the striking rod comprises a peripheral outer surface and a longitudinal axis; and wherein the striking rod and the gear box are connected through a sliding connection structure which allows the striking rod to be moved along its longitudinal axis and which prevents the striking rod from rotating to around its longitudinal axis,
wherein the impact wheel is movable relative to the rotating shaft between a first axial position where the projection of the impact wheel is contactable with the end face of the second end of the striking rod and a second axial position where the projection is contactable with the flat surface of the striking rod.
2. The nailer device as recited in claim 1 , wherein the sliding connection structure comprises a first surface on a peripheral outer surface of the striking rod and a second surface of the gear box that is engagable with the first surface.
3. The nailer device as recited in claim 2 , wherein the first and second surfaces are flat surfaces.
4. The nailer device as recited in claim 2 , wherein the first and second surfaces are toothed surfaces.
5. The nailer device as recited in claim 1 , wherein the sliding connection structure comprises at least one connection member between the striking rod and the gear box and at least one groove formed on one of the striking rod and the gear box wherein a portion of the connection member extends into the groove.
6. The nailer device as recited in claim 5 , wherein the connection member is attached to the other of the striking rod and the gear box than that which the at least one groove is formed on.
7. The nailer device as recited in claim 5 , wherein the other of the striking rod and the gear box is formed with another groove and a portion of the connection member is arranged in the another groove.
8. The nailer device as recited in claim 1 , wherein the striking rod comprises a first end for striking a nail and a second end to be impacted, the second end has an end face, and the striking rod comprises a flat surface on a peripheral outer surface thereof.
9. The nailer device as recited in claim 8 , wherein the flat surface adjoins the end face.
10. The nailer device as recited in claim 8 , wherein the transmission mechanism comprises a rotating shaft and an impact wheel that is mounted surrounding the rotating shall and rotates therewith, the impact wheel having at least one projection on its periphery.
11. The nailer device as recited in claim 1 , wherein a surface of the projection of the impact wheel, which contacts the flat surface of the striking rod in the second axial position, is parallel with the flat surface.
