Abstract

A safety device for tackers includes a safety slide slidably connected to the outlet of the tacker and the safety slide has a stop protruding from the inside thereof. The rod has one end contacts the stop and the other end of the rod has a plastic tip connected thereto. An ignition spring is connected between the plastic tip and a safety switch. A recovery spring is connected to another position of the rod to position the rod. The safety slide is slidably connected to grooves of the tacker. When the safety slide contacts against an object to be stapled, the rod is pushed by the stop and activates the ignition spring to activate the safety switch so as to reduce the impact of the rod and the safety switch.

First claim

What is claimed is:

1. A safety device for a tacker configured to eject a staple, comprising:
a body having an outlet defined through a front end thereof, and enclosing staple ejection electronics and an operation path defied in the body, the operation path communicating with the outlet;
a rod movably located in the operation path and having a contact portion formed at a first end thereof, a connection portion formed at a mediate portion of the rod, a recovery spring mounted to the connection portion to provide a recovery force to the rod, a seat formed at a second end of the rod and having a tip extending therefrom;
a safety slide being a U-shaped plate and having two wings extending from two sides thereof, the safety slide slidably mounted to an exterior of the front end of the body and located corresponding to the outlet of the body such that the two wings surround a portion of the front end of the body and extend into the body, the safety slide having a U-shaped bottom edge formed at a distal end thereof, a stop extending from the safety slide and located corresponding to the contact portion of the rod, when the safety slide is slid, the stop contacts the contact portion and drives the rod to be retracted into the body;
an ignition spring mounted to the tip of the seat, and
a safety switch located in the body and having a contact plate extending therefrom, the contact plate being pushed by the ignition spring to send a tacking signal when the rod is retracted back into the body;
wherein the U-shaped bottom edge of the safety slide and a portion of the body extending parallel to the U-shaped bottom edge of the safety slide are configured to extend adjacent to an object that will receive an ejected staple;
wherein the safety slide is pressed onto the object that will receive the ejected staple until the body makes contact with the object that will receive the ejected staple, said pressing of the safety slide causing the contact plate of the safety switch to be pushed; and
wherein contact between the object that will receive the ejected staple and the safety slide is visible from the exterior of the front end of the body.

2. The safety device for a tacker as claimed in claim 1 , wherein an index portion formed at the safety slide includes a side index portion on each of the two wings of the safety slide.

3. The safety device for a tacker as claimed in claim 1 , wherein an index portion formed at the safety slide includes a front index portion on a front of the safety slide.

4. The safety device for a tacker as claimed in claim 1 , wherein a notch is defined in the bottom edge of the safety slide.

5. The safety device for a tacker as claimed in claim 1 , wherein the tip is located at a distal end of the seat and movable with the rod in an axial direction of the rod.

6. The safety device for a tacker as claimed in claim 1 , wherein the contact plate of the safety switch is pushed by the ignition spring which is moved along an axial direction of the rod.

7. A tacker configured to eject a staple, comprising:
a body having an outlet defined through a front end thereof, and enclosing staple ejection electronics and an operation path defied in the body, the operation path communicating with the outlet
a rod movably located in the operation path and having a contact portion formed at a first end thereof;
a safety slide being a U-shaped plate and having two wings extending from two sides thereof, the safety slide slidably mounted to an exterior of the front end of the body and located corresponding to the outlet of the body such that the two wings surround a portion of the front end of the body and extend into the body, the safety slide having a U-shaped bottom edge formed at a distal end thereof, a stop extending from the safety slide and located corresponding to the contact portion of the rod, when the safety slide is slid, the stop contacts the contact portion and drives the rod to be retracted into the body;
a safety switch located in the body and having a contact plate extending therefrom, the contact plate being pushed to send a tacking signal when the rod is retracted back into the body;
wherein the U-shaped bottom edge of the safety slide and a portion of the body extending parallel to the U-shaped bottom edge of the safety slide are configured to extend adjacent to an object that will receive an ejected staple;
wherein the safety slide is pressed onto the object that will receive the ejected staple until the body makes contact with the object that will receive the ejected staple, said pressing of the safety slide causing the contact plate of the safety switch to be pushed; and
wherein contact between the object that will receive the ejected staple and the safety slide is visible from the exterior of the front end of the body.

8. The safety device for a tacker as claimed in claim 7 , wherein an index portion formed at the safety slide includes a side index portion on each of the two wings of the safety slide.

9. The safety device for a tacker as claimed in claim 7 , wherein an index portion formed at the safety slide includes a front index portion on a front of the safety slide.

10. The safety device for a tacker as claimed in claim 7 , wherein a notch is defined in the bottom edge of the safety slide.
