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 tacker configured to eject a staple, the tacker comprising:
a body enclosing staple ejection electronics and an operation path defined in the body;
a rod movably located in the operation path and having a contact portion formed at a first end thereof proximal an outlet of the tacker, a connection portion formed at a mediate portion of the rod, and a seat formed at a second end of the rod;
a tip extending from the seat;
an ignition spring mounted to the seat, and
a safety switch located in the body and having a contact plate extending therefrom, the contact plate touching the ignition spring and being pushed by the ignition spring to send a tacking signal when the rod is pushed;
wherein the contact plate of the safety switch is pushed by the ignition spring, which is moved along an axial direction of the rod.

2. The tacker of claim 1 , further comprising a recovery spring mounted to the rod to provide a recovery force to the rod.

3. The tacker of claim 2 , wherein the recovery spring is mounted to the connection portion of the rod.

4. The tacker of claim 3 , wherein the recovery spring is mounted to a protrusion of the connection portion of the rod.

5. The tacker of claim 4 , wherein the protrusion is received in the recovery spring.

6. The tacker of claim 2 , wherein the recovery spring is configured to compress to provide the recovery force.

7. The tacker of claim 1 , wherein the ignition spring compresses to absorb an impact between the rod and the safety switch.

8. The tacker of claim 1 , wherein the rod is fixedly coupled to a safety slide extending from the housing.

9. The tacker of claim 8 , wherein the contact portion contacts the safety slide, such that movement of the safety slide causes movement of the rod.

10. The tacker of 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.

11. The tacker of claim 1 , wherein the tip comprises plastic.

12. The tacker of claim 1 , wherein the tip is received in the ignition spring.

13. The tacker of claim 1 , wherein the tacker is a corded electric tacker.
