Description

Electric stapler

The invention relates to an electric stapler, in particular to an electric stapler for automatically nailing.

As described in the patent TW577378, the conventional electric stapler is provided with a button or a touch piece inside the opening. When the paper is inserted into the opening and the paper is pushed by the button, the switch can be activated to drive the nailing device to perform the nailing operation.

However, the switch button of this type of structure relies entirely on the paper to push, but it must retain the elastic force of the return. Therefore, the thrust of the touch switch is not small for the paper, and the front end of the paper may be folded or rolled up by pushing the button. This may result in inaccurate binding positions or paper staggering.

In addition, the push button switch (position corresponding to the leading end of the paper) and the nailing portion (position corresponding to the desired binding) are relatively close, and there is a possibility of damaging the switch when the nail is hit.

Therefore, how to provide an electric stapler that is easy to trigger a nail and has a good reset mechanism has become an urgent problem to be solved.

The following is a description of the possible embodiments of the present invention, and is not intended to limit the scope of the invention as claimed.

Referring to FIG. 1 to FIG. 9 , the present invention provides an electric stapler comprising a body 10 , a nailing device 20 , a photoelectric switch 30 , a pivoting member 40 and a triggering member 50 .

The body 10 encloses an accommodating space and has a front end opening 11 having a working plane 12 at the front end opening 11; the nailing device 20 is disposed in the accommodating space and includes a vertical direction a nailing mechanism 21 capable of moving between a starting position and a nailing position, the nailing mechanism 21 having a tendency to maintain the starting position, the nailing mechanism 21 having a nailing portion 211 The photoelectric switch 30 is disposed in the accommodating space of the body 10 and connected to the nailing device 20. When the photoelectric switch 30 is activated, the nailing mechanism 21 of the nailing device 20 is driven to move to the nailing position. The nailing portion 211 is fired by a nail; the pivoting member 40 is pivotally disposed at the front end opening of the body 10, and the other end has a pushing portion 41. The pivoting member 40 is further away from the body than the nailing portion 211. The front end opening 11 of the pivoting member 40 has a top portion 42 facing the front end opening 11. The pivoting member 40 is pivotable between a first position and a second position, and the pivoting member 40 is wound around the front end. Pivot pivoting The pivoting portion is parallel to the vertical direction. When the pivoting member 40 is in the first position, the pushing portion 41 is closer to the front end opening 11. When the pivoting member 40 is in the second position, the pushing portion 41 is farther away from the The front end opening 11 is inclined by the elastic force of a resilient means (in this embodiment, a spring 43) to maintain the first position; the touch member 50 is movably disposed on the photoelectric switch 30 Between the pushing portions 41 of the pivoting member 40, the photoelectric switch 30, the driving member 50 and the pushing portion 41 of the pivoting member 40 are sequentially arranged along the length direction, and the pivoting member 40 and the driving member 50 are independent of each other. The two components, the trigger member 50 is movable between a return position and a touch position, and the touch member 50 has a tendency to maintain the return position, when the abutting top 42 of the pivot member 40 is pushed by a sheet of paper 70. The pivoting member 40 moves to the second position to push the trigger member 50 to move to the touch position, and the photoelectric switch 30 is activated when the touch member 50 is in the touch position.

In this embodiment, the abutting top 42 of the pivoting member 40 has a V-shaped angle toward the front end opening 11 of the body. The V-shaped angle is a right angle, and the V-shaped angle is for a corner of the paper 70 to be abutted. Preferably, a rear end of the body 10 is connected to the front end opening in a longitudinal direction. When the pivoting member 40 is in the second position, the angle bisector of the V-shaped angle is parallel to the length direction. That is to say, when the pivoting member 40 is pushed by the paper 70 to the position to be bound, the staple can be bound to the corner of the paper 70 at an oblique angle of 45 degrees (the direction of the nail is perpendicular to the longitudinal direction), however, the paper 70 can also be used. One of the two legs that abuts the V-shaped corner, as shown in Figures 7 and 8, can also achieve the effect of pushing the pivoting portion 40.

In addition, the trigger member 50 further includes an elastic member 51. The actuator member 50 is positioned to the bottom of the body 10 by the elastic member 51 and has a tendency to maintain the return position. In addition, the photoelectric switch 30 can adopt U-shaped photoelectricity. The switch has an induction slot 31 and a light is emitted from a side of the sensing slot 31 and is detected by the other side of the sensing slot 31. When the trigger member 50 is located at the touch position, the trigger member 50 is at least partially located. The light is blocked in the sensing slot 31, and when the photoelectric switch 30 does not detect light, the nailing device 20 is driven to perform nailing.

On the other hand, an elastic guiding member 60 is further disposed on the front end of the nailing mechanism 21, and the elastic guiding member 60 includes a guiding portion 61, an elastic means 62 and a pivot The connecting portion 63 is pivoted to the front end of the nailing mechanism 21, and the guiding portion 61 extends in the direction of the nailing portion 211 to swing up and down, and the elastic means 62 has the guiding portion 61 a tendency to swing downward (for example, an abutting surface that is biased against the front end of the nailing mechanism 21 to provide an elastic force of the guiding portion 61), and the elastic guiding member when the nailing mechanism 21 moves to the nailing position The guiding portion 61 of the 60 abuts against the paper 70 placed on the working plane 12, causing the guiding portion 61 to swing upward and compress the elastic means 62, whereby the guiding portion 61 further advances the paper 70 Pulling the nail portion 211 to fix the paper 70 and ensure that the binding position is correct.

In actual use, the user inserts the paper 70 to be bound into the front end opening 11 of the body 10 with one corner thereof until it abuts against the abutting top 42 of the pivoting member 40 to push the pivoting member 40 to the second position to push The touch member 50 touches the photoelectric switch 30, thereby driving the nailing mechanism 21 to drop and fire the staples, thereby completing the automatic binding work.

Wherein, the cooperation of the pivoting member 40 and the actuating member 50 enables the paper 70 to be pushed with a small force to achieve the effect of the touch and the firing, and the V-shaped abutting portion 42 can ensure the precise binding position and avoid the paper concave fold. Or roll up.

In summary, the present invention can easily trigger automatic nailing, and can ensure accurate binding position, and the paper does not need to be strongly pushed, and the paper can be prevented from being folded or rolled up. In addition, the switch is far away from the nailing mechanism and does not hit. The nail action is damaged and it is very effective.
