Adjusting device for magazine of nailers

Abstract

A magazine includes a base having nail slots defined therein and a cover is slidably mounted to the base. A first end member and a second end member are respectively connected to the first and second ends of the cover. A plurality of rods extend through the first end member, the nail slots and the second end member. Each rod has a biasing member and a pushing member which is biased by the biasing member so as to push the nails in the nail slots. A plurality of bolts extend through the second end member and contact against the second end of the cover so that when rotating the bolts to move the second end member away from the second end of the cover, the rods are straightened. The pushing members on the rods push the nails of different lengths to be arranged in order in the magazine.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 to 7, the magazine of the present invention comprises a base 1 having two guide rails 10, 11 on two sides thereof and a plurality nail slots 12 are defined in the base 1 and located between the guide rails 10, 11. A cover 2 has two guide grooves 20, 21 in which the two guide rails 10, 11 are movably engaged so that the cover 2 is slidably mounted to the base 1. A space area 22 is defined in an inside of the cover 2 and includes a first space 220 and a second space 221. The space area 22 is located corresponding to the nail slots 12 of the base 1. Two first positioning means 23, 24 are located at a first end of the cover 2 and a second positioning member 25 is located at a second end of the cover 2.

An end member unit 3 includes a first end member 30 and a second end member 31, wherein the first end member 30 is connected to the first end of the cover 2 and the second end member 31 is connected to the second end of the cover 2. The first end member 30 includes two first connection means 301, 302 which are connected with the two first positioning means 23, 24 of the cover 2. The second end member 31 includes a second connection means 311 which is connected with the second positioning means 25 of the cover 2. The first end member 30 includes a plurality of first through holes 304, 305 and the second end member 30 includes a plurality of second through holes 314, 315. A plurality of rods 4 extend through the first through holes 304, 305 and the second through holes 314, 315. Each rod 4 has a biasing member 5 and a pushing member 6 which is biased by the biasing member 5 and moves along the rod 4 so as to push the nails in the space area 22.

There are two ways to connect the first and second end members 30, 31 to the cover 2. The first way is that each of the first positioning means 23, 24 and the second positioning means 25 is a protrusion and each of the first connection means 301, 302 and the second connection means 311 is a recess, the protrusions are inserted into the recesses. The other way is that each of the first positioning means 23, 24 and the second positioning means 25 is a recess and each of the first connection means 301, 302 and the second connection means 311 is a protrusion, the protrusions are inserted into the recesses.

Each of the first positioning means 23, 24 and the second positioning means 25 is a hole each of the first connection means 301, 302 and the second connection means 311 is a hole. The rods 4 extend through the aligned holes of the first positioning means 23, 24, the second positioning means 25, the first connection means 301, 302 and the second connection means 311. The second end member 302 includes threaded holes 312 and bolts 7 are threadedly connected to the threaded holes 312. The bolts 7 contacts the second end of the cover 2 so as to move the second end member 302 away from the second end of the cover 2 to straighten the rods 4.

The cover 2 is slid to open the magazine and long nails 8 are inserted in the nail slots 12, the cover 2 is then slid to close the magazine. The pushing ends 60 of the pushing member 6 are moved by the biasing members 5 and moved in the nail slots 12 to push the nails 8 as shown in FIG. 6, so that the long nails 8 are arranged in order.

When short nails 8 are inserted in the nail slots 12, the pushing ends 60 of some of the pushing members 6 are moved by the biasing members 5 and moved in the nail slots 12 to push the nails 8 as shown in FIG. 8, so that the long nails 8 are arranged in order.

While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
