Hammer tacker

Abstract

The hammer tacker includes a shell, a handle, and a striking mechanism. The shell is made of a mixture of fiberglass and nylon by injection molding. The shell encloses a receiving room and has a bottom opening extending along the longitudinal direction of the shell and communicating with the receiving room. The handle is disposed on the rear end of the shell. The striking mechanism is made of metal and includes a magazine and a striker. The magazine is received in the receiving room. An end of the magazine is pivotally connected to the rear end of the shell, and the other end tends to move outward due to an elastic element. At end of the striker is disposed on the inner wall of the shell. When the magazine is hit upward, the striker strikes the nails out.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(7) Please refer to FIGS. 1 to 6, the hammer tacker of the present invention includes a shell 10,10a, a handle 20,20a, and a striking mechanism.

(8) The shell 10,10a is made of a mixture of fiberglass and nylon by injection molding wherein the mixture is composed of 30% to 70% of fiberglass by weight and 70% to 30% of nylon by weight. Preferably, the mixture is composed of 50% of fiberglass by weight and 50% of nylon by weight, and the fiberglass and the nylon are blended and granulated and then form the shell 10,10a by injection molding. The shell 10,10a has a first end and a second end at two opposite ends thereof along a longitudinal direction of the shell 10,10a. The shell 10,10a encloses a receiving room and has a bottom opening extending along the longitudinal direction and communicating with the bottom opening. The handle 20,20a is connected to the second end of the shell 10,10a. The striking mechanism is made of metal and includes a magazine 31,31a and a striker 32,32a. The magazine 31,31a is arranged in the receiving room. The magazine 31,31a has a third end and a fourth end at two opposite ends along a longitudinal direction thereof. The fourth end of the magazine 31,31a is pivotally connected to the second end of the shell 10,10a. The third end of the magazine 31,31a corresponds to the first end of the shell 10,10a. The magazine 31,31a is under an elastic force by an elastic element 33,33a so that the third end of the magazine 31,31a tends to move outward. Preferably, the elastic element 33,33a is an elastic plate. An end of the elastic plate is fixed to the inner wall of the shell 10,10a facing to the magazine 31,31a, and an other end of the elastic plate abuts against the magazine 31,31a. An end of the striker 32,32a is disposed on the inner wall of the shell 10,10a, an other end of the striker 32,32a positionally corresponds to the magazine 31,31a. When the third end of the magazine 31,31a is hit upward, the third end of the magazine 31,31a is moved toward the striker 32,32a so that the nails in the magazine 31,31a is stroke out by the striker 32,32a.

(9) Furthermore, in the first embodiment of the present invention, as shown in FIGS. 1 to 3, the handle 20 is sleeved onto the second end of the shell 10 and extends to a portion of the shell 10 between the first end and the second end. The shell 10 has an abutting portion in a predetermined distance from the second end. The abutting portion is adapted for a lower end of the magazine 31 to abut against so that the magazine 31 is unable to pivot downward unlimitedly. Besides, the magazine 31 comprises a limiting rail and a nail rail wherein the limiting rail covers the nail rail and is pivotally connected to the shell 10. The nail rail is filled with nails and is able to be pulled backward for refilling the nails. The shell 10 has a positioning element near the abutting portion. The positioning element is selectively inserted into a positioning hole on the nail rail to prevent the nail rail from being pulled backward.

(10) In the second embodiment, as shown in FIGS. 4 to 6, the shell 10a has a terminal end extending from the second end away from the first end. The handle 20a is sleeved onto the terminal end. That is, the magazine 31a is substantially pivotally arranged in front of the handle 20a. The magazine 31a has a structure similar to the stapler. Specifically, the striker 32a is formed with an elongated slot 321, and the magazine 31a is formed with a protrusion 311 inserted into the elongated slot 321 to be linearly slidable along the elongated slot 321. Thus, the maximum pivot angle of the magazine 31a is restricted.

(11) In conclusion, the hammer tacker of the present invention has a shell made of special material. As a result, the weight is reduced, and the noise and the shaking are also reduced. Besides, the shell is easy to manufacture due to the injection molding procedures so that the cost is also reduced. In addition, the pivoting magazine makes the structure easier.
