Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of a tack fixing apparatus according to the present invention, and FIGS. 2a and 2b are views for explaining the operation principle of a tack fixing apparatus according to the present invention.

Referring to FIG. 1, a tack fixing apparatus according to the present invention includes a main body 100 having a handle 110 and a trigger 120, which can be gripped by a user, and a trigger 120; And a pushpin magazine 200 mounted on the main body 100 and containing a plurality of pushpins.

2A and 2B, the tack fixing apparatus of the present invention includes a motor driven according to the pulling of the trigger 120; A battery 125 for driving the motor; A first gear 131 rotated counterclockwise by the rotation of the motor; A second gear 132 meshed with the first gear 131 and rotated (clockwise rotated) clockwise by rotation of the first gear 131; A third gear 133 meshed with the second gear 132 and rotated (counterclockwise) in the counterclockwise direction by rotation of the second gear 132; A piston 150 having a rack gear 151 meshed with the third gear 133 on its outer circumferential surface and provided with a punching portion 152 at one end; And an elastic spring 157 connected to the other end of the piston 150 and fixed to the main body 100; And a guide cylinder 153 in which the piston 150 and the punching unit 152 can flow into the internal space.

The main body 100 incorporates a motor, a battery 125, first to third gears 131, 132 and 133, a piston 150, a spring 157 and a guide cylinder 153.

When the user pulls the trigger 120, the electrical contact to which the motor and the battery 125 are connected is turned on to drive the motor.

The first to third gears 131, 132 and 133 can be realized as a cylindrical spur gear having a rotating shaft at the center, and the rotating shaft of the motor is inserted into the shaft of the first gear 131.

Here, the first gear 131, the second gear 132, and the third gear 133 are sequentially increased in gear size. That is, even though the first gear 131 is set to rotate the motor several times by pulling the trigger 120 with the smallest gear, the third gear 133 having the largest size through the second gear 132 It is designed to be rotated once. That is, the first and second gears 131 and 132 are provided to reduce the number of rotations of the motor to one rotation.

For example, the first gear 131 is designed to rotate five times by the motor, and the second gear 132 is designed to rotate twice, and the third gear 133 is designed to rotate once.

The third gear 133 is formed with a tooth along the circumferential direction, but some gears are removed. That is, the third gear 133 has an area where no gear is formed on the cylindrical surface, and some gears are not present and the gears are not continuously connected.

Therefore, as the user pulls the trigger 120, the motor rotates, the first gear 131 rotates in the reverse direction, the second gear 132, which is gear-coupled to the first gear 131, is rotated forward, The third gear 133, which is gear-coupled to the second gear 132, rotates forward.

2A, the rack gear 151 of the piston 150 engaged with the third gear 133 is linearly moved (leftward in FIG. 2A) by the forward rotation of the third gear 133, (157) is pressed.

Thereafter, when the third gear 133 reaches the rack gear 151 of the piston 150, the third gear 133 is rotated by the third gear 133, And the rack gear 151 of the piston 150 are released and the restoring force of the compressed spring 157 causes the piston 150 to be instantaneously inserted into the guide cylinder 153 as shown in FIG. 150 pushes the pushpin of the pushpin magazine 200, so that the pushpin is fixed to the object such as the bulletin board.

At this time, the user must pull the trigger 120 until the pushpin is fired from the pushpin fixture (which defines the release of the pushpin from the fixture by the release pressure of the spring 157 is defined as firing). Of course, when the user is continuously pulling the trigger 120, the operation of pushing and releasing the spring 157 is repeated, so that a continuous pushpin can be fired. Here, the pushpin is fired every time the spring 157 is pressed and released.

Note that '127' in FIGS. 2A and 2B is a contact terminal of the trigger 120 and a motor-connected electric wire. As the trigger 120 is pulled, the contact terminal is turned on to drive the motor.
