DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawings and initially to FIGS. 1-3, a flooring nailer in accordance with the preferred embodiment of the present invention comprises a main body 10, and a handle structure 20 mounted on the main body 10.

The main body 10 has a first end provided with a nail striking portion 11 and a second end provided with a nail outlet 12 for ejecting the flooring nails (not shown) outward by striking the nail striking portion 11 by a hammer not shown). The nail outlet 12 has a side provided with a receiving portion 13 for receiving the flooring nails. The main body 10 has a side formed with a protruding transverse bar 14.

The handle structure 20 includes a fixing seat 21, and a handle 27.

The fixing seat 21 of the handle structure 20 is secured on the transverse bar 14 of the main body 10. Preferably, the fixing seat 21 of the handle structure 20 is integrally formed with the transverse bar 14 of the main body 10. The fixing seat 21 of the handle structure 20 has a first end formed with a substantially L-shaped locking portion 26 and a second end formed with a counterbore 25. The fixing seat 21 of the handle structure 20 has a side formed with a substantially L-shaped support rack 22 located adjacent to the locking portion 26. The support rack 22 of the fixing seat 21 has a first section formed with a tapered face 23 located adjacent to the locking portion 26 and a second section formed with a screw bore 24 aligning with the counterbore 25.

The handle 27 of the handle structure 20 is combined with the fixing seat 21 and has a first end formed with a substantially L-shaped snapping portion 28 snapped on the locking portion 26 of the fixing seat 21 and a second end formed with a grip portion 270. The handle 27 of the handle structure 20 has a side formed with a cylindrical pivot shaft 29 located adjacent to the snapping portion 28 and pivotally mounted on the support rack 22 of the fixing seat 21. The pivot shaft 29 of the handle 27 has an end having two opposite sides each formed with a tapered face 30 rested on the tapered face 23 of the support rack 22 of the fixing seat 21. The pivot shaft 29 of the handle 27 is formed with a through hole 31.

The handle structure 20 further includes a screw member 40 extended through the counterbore 25 of the fixing seat 21 and the through hole 31 of the pivot shaft 29 of the handle 27, and screwed into the screw bore 24 of the support rack 22 of the fixing seat 21, so that the pivot shaft 29 of the handle 27 is pivotally mounted on the support rack 22 of the fixing seat 21.

The handle structure 20 further includes a spring 32 mounted on the screw member 40 and urged between a wall of the counterbore 25 of the fixing seat 21 and an end face of the pivot shaft 29 of the handle 27 for urging the pivot shaft 29 of the handle 27 toward the support rack 22 of the fixing seat 21.

In operation, referring to FIGS. 1-7, the tapered face 23 of the support rack 22 of the fixing seat 21 is rested on the tapered face 30 of one side of the pivot shaft 29 of the handle 27 as shown in FIG. 2. Then, the handle 27 is rotated relative to the fixing seat 21, so that the pivot shaft 29 of the handle 27 is pivoted relative to the support rack 22 of the fixing seat 21 to detach the tapered face 23 of the support rack 22 of the fixing seat 21 from the tapered face 30 of one side of the pivot shaft 29 of the handle 27. After the handle 27 is rotated relative to the fixing seat 21 through 90 degrees, the snapping portion 28 of the handle 27 is rested on the locking portion 26 of the fixing seat 21. Then, the handle 27 is lifted relative to the fixing seat 21 to compress the spring 32, so that the snapping portion 28 of the handle 27 is located above the locking portion 26 of the fixing seat 21 as shown in FIG. 5. Then, the handle 27 is rotated relative to the fixing seat 21 successively. After the handle 27 is rotated relative to the fixing seat 21 through 180 degrees, the snapping portion 28 of the handle 27 is aligned with the locking portion 26 of the fixing seat 21 as shown in FIG. 6.

Then, the lifting force applied on the handle 27 is released, so that the pivot shaft 29 of the handle 27 is moved toward the support rack 22 of the fixing seat 21 by the restoring force of the spring 32, and the snapping portion 28 of the handle 27 is moved into and locked in the locking portion 26 of the fixing seat 21 as shown in FIG. 7, thereby forming a first locking effect so as to fix the handle 27 on the fixing seat 21. At this time, the handle 27 is rotated relative to the fixing seat 21 through 180 degrees, so that the tapered face 23 of the support rack 22 of the fixing seat 21 is rested on the tapered face 30 of the other side of the pivot shaft 29 of the handle 27, thereby forming a second locking effect so as to fix the handle 27 on the fixing seat 21.

Accordingly, the snapping portion 28 of the handle 27 is locked in the locking portion 26 of the fixing seat 21 to form a first locking effect, and the tapered face 23 of the support rack 22 of the fixing seat 21 is rested on the tapered face 30 of the pivot shaft 29 of the handle 27 to form a second locking effect, so that the handle 27 is fixed on the fixing seat 21 rigidly and stably, thereby preventing the handle structure 20 from detaching from the main body 10 due to the shock or vibration produced during operation of the flooring nailer. In addition, the handle 27 of the handle structure 20 can be pivoted relative to the fixing seat 21 by the pivot shaft 29, so that the handle 27 of the handle structure 20 is parallel with the main body 10, thereby folding the handle structure 20 so as to facilitate package, storage and transportation of the flooring nailer. Further, the spring 32 is urged between the handle 27 and the fixing seat 21 to prevent the handle 27 from detaching from the fixing seat 21. Further, the spring 32 can absorb the shock or vibration produced during operation of the flooring nailer, thereby providing a shock-absorbing effect.

Referring to FIG. 8, a flooring nailer in accordance with another embodiment of the present invention is shown, wherein the fixing seat 21 of the handle structure 20 is secured on an outer wall of the main body 10.
