Electric nail gun

The present invention relates to a nail gun, and more particularly to an electric nail gun.

The conventional electric nail guns sequentially arrange a driving shaft, a nailing piece and a nail to be fired in a firing direction, and use the driving shaft to quickly push the nailing piece downward to fire the lower nail. And the nail can be driven into the target to be fixed, however, since the drive shaft, the nail piece and the nail are all disposed along the firing direction, the height of the electric nail gun in the firing direction is high. , large size.

In order to solve this problem, as shown in U.S. Patent No. 4,941,262, the nail is designed to be arcuate, and when pushed by the drive shaft, the nail is fired down an arcuate track. Thereby, the height and the volume of the electric nail gun in the firing direction are reduced. However, since the arc shape of the nailing piece has to be well matched with the curved track, the nailing piece requires a high precision process technology. Otherwise, the operation may not be smooth when the nail is hit, the nail pin cannot be successfully fired, and after a period of use, the nail piece is also easily caused to be unsmooth due to loss of deformation, resulting in the nail not being able to be successfully fired.

Accordingly, it is an object of the present invention to provide an electric nail gun that solves the above problems.

Therefore, the electric nail gun of the present invention is suitable for installing a plurality of nails, and the nails are respectively shot in a firing direction. The electric nail gun comprises a casing unit, an electromagnetic driving unit, and a firing unit.

The casing unit includes a guide groove formed inside the casing unit and extending in a driving direction not parallel to the firing direction.

The electromagnetic driving unit is disposed in the casing unit and includes a reciprocating drive shaft.

The firing unit is disposed in the casing unit, and includes a guiding member movable in the guiding direction along the driving direction by the driving shaft, and a guiding member disposed on the guiding member and having a free end and a reverse a punching piece of the firing end of the free end, the free end being movably disposed in the movable member in a moving direction not parallel to the driving direction, wherein the firing end is used to fire one of the nails, and the nailing piece is In the shape of a straight plate, when the driving member drives the nailing piece to drive the nailing piece toward the nailing pin, the nailing piece moves in the moving direction by the free end to maintain a straight shape during the firing process.

The effect of the present invention is that, with the above design, even if the driving direction is not parallel to the firing direction, the nail can be moved in the moving direction during the firing process by the free end of the nailing piece. The sheet maintains a straight shape during the firing process. Thus, the straight-shaped nail-shaped sheet can still be used while reducing the height and volume of the electric nail gun, so that the manufacturing cost can be reduced, and the smooth operation and the durability of the product can be maintained. The effect of the degree.

Referring to FIG. 1 , FIG. 2 and FIG. 3 , an embodiment of the electric nail gun of the present invention is suitable for installing a plurality of staples 9 and respectively exposing the staples 9 in a firing direction X. The electric nail gun comprises a The casing unit 2, an electromagnetic driving unit 3, and a firing unit 4.

The casing unit 2 includes a casing 21, a guide groove 22 formed inside the casing 21 and extending in a driving direction Y not parallel to the firing direction X, and a rotatably disposed on the casing 21 The runner 23, wherein the guide groove 22 extends in a straight line and has a square groove shape.

The electromagnetic driving unit 3 is disposed in the casing unit 2 and includes a reciprocating drive shaft 31.

The firing unit 4 is disposed in the casing unit 2, and includes a guiding member 41 that is movable in the guiding direction Y along the driving direction Y by the driving shaft 31, and is disposed on the guiding member 41 and has A free end 421 and a striking piece 42 opposite the firing end 422 of the free end 421.

The guiding member 41 has a body 411 movable back and forth in the guiding slot 22, a mounting shaft 412 disposed on the body 411 and passing through the free end 421 of the nailing piece 42, and a housing 21 disposed on the housing 21 An elastic portion 413 between the body 411 and the body 411.

The setting axis 412 extends along a moving direction Z that is not parallel to the driving direction Y, wherein the moving direction Z is also not parallel to the firing direction X.

The elastic portion 413 is configured to provide a restoring force of the body 411 toward the driving shaft 31. In the embodiment, the elastic portion 413 is substantially annular and sleeved on the rotating wheel 23, but the elastic portion 413 is also It can be another architecture that can provide this resilience.

The free end 421 of the nailing piece 42 is movably disposed in the movable direction Z on the setting shaft 412. The firing end 422 is used to fire one of the nails 9 and the nailing piece 42 has a straight shape.

When the user controls the electric nail gun to perform the firing, the driving shaft 31 generally moves downward along the driving direction Y, and pushes the body 411 to move downward along the guiding slot 22 to drive the nailing piece 42 toward The staples 9 are fired. At this time, the free end 421 of the nail piece 42 moves in the movable direction Z to maintain the nail piece 42 in a straight shape during the firing process.

Through the above description, the advantages of this embodiment can be summarized as follows:

1. By designing the nailing piece 42 as a straight plate, and the free end 421 of the nailing piece 42 is movably disposed on the guiding member 41, even if the driving direction Y is not parallel to the firing direction X In this case, the free end 421 of the nailing piece 42 can still be moved along the moving direction Z during the firing process to maintain the nailing piece 42 in a straight shape during the firing process, so that the electric nail gun can be reduced in the In the case of the height and volume in the firing direction X, the straight-shaped nailing piece 42 can still be used, so that it is not necessary to use a high-precision process technology as in the prior art, and the manufacturing cost can be reduced, and even if the use time is shorter For a long time, the straight-shaped nail piece 42 is not easily deformed and the operation is not smooth, so it also has the effect of maintaining smooth operation and improving product durability.

2. By designing the installation shaft 412 to extend along the movable direction Z and passing the free end 421, the mechanism can be freely moved by the mechanism that can be freely moved in the movable direction Z, thereby achieving the novel The effect of the appeal.

3. By designing the guide groove 22 to extend in a straight line, the body 411 can be moved in a straight line during the firing process, so that a smooth motion track can be obtained, thereby improving the smoothness and durability of the product.

4. The elastic portion 413 is provided to constantly provide a restoring force of the body 411 to the driving shaft 31, so that the body 411 can automatically return to the original position after each firing, thereby facilitating the next firing.

In summary, it is indeed possible to achieve the purpose of the novel.

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
