Abstract

A nail gun includes a gun body, a safety unit and an adjusting unit. The safety unit includes a first safety member movable relative to the gun body, and a second safety member for being pushed by the first safety member. The adjusting unit includes a switch member movable between a deep-drive position and a shallow-drive position. The switch member has a first abutment surface aligned with the first safety member when the switch member is at the deep-drive position, and a second abutment surface aligned with the first safety member when the switch member is at the shallow-drive position.

First claim

What is claimed is:

1. A nail gun comprising:
a gun body including a muzzle, and an operation portion for activating firing operation;
a safety unit including a first safety member that is movable relative to said muzzle in a lengthwise direction of said gun body, and a second safety member that is able to be pushed by said first safety member to actuate said operation portion and that is movable relative to said gun body between an initial position and an actuating position, said first safety member has an abutment portion, said second safety member being distal from a rear portion of said gun body when said second safety member is at the initial position, said second safety member being proximate to said rear portion of said gun body and actuating said operating portion when said second safety member is at the actuating position; and
an adjusting unit including a fixing member that is co-movably mounted to said second safety member, and a switch member that is disposed between said fixing member and said second safety member and that is movable relative to said second safety member in a lateral direction of said gun body between a deep-drive position and a shallow-drive position, said switch member being pushed by said first safety member so as to move said second safety member, and having a first abutment surface, and a second abutment surface that is misaligned from said first abutment surface in the lengthwise direction and that is located ahead of said first abutment surface by a distance, said first abutment surface being aligned with said abutment portion of said first safety member when said switch member is at the deep-drive position, said second abutment surface being aligned with said abutment portion of said first safety member when said switch member is at the shallow-drive position;
wherein, when a pressing end of said first safety member is pressed against an object, said first safety member first moves toward said second safety member in the lengthwise direction by a distance before said abutment portion of said first safety member is in contact with said first abutment surface or said second abutment surface of said switch member.

2. The nail gun as claimed in claim 1 , wherein said second safety member has two positioning structures that are disposed in the lateral direction, said adjusting unit further including a positioning assembly that is mounted to said switch member, said positioning assembly being removably coupled to one of said positioning structures when said switch member is at the deep-drive position, said positioning assembly being removably coupled to the other one of said positioning structures when said switch member is at the shallow-drive position.

3. The nail gun as claimed in claim 2 , wherein said positioning assembly includes a latch member that is movable relative to said switch member and that is removably coupled either one of said positioning structures of said second safety member.

4. The nail gun as claimed in claim 3 , wherein each of said positioning structures is configured as a recess, said latch member being configured as a spherical body, said positioning assembly further including a resilient member that resiliently biases said latch member to removably engage a selective one of said positioning structures.

5. The nail gun as claimed in claim 2 , wherein said positioning assembly includes an operating member that slidably engages said switch member, said switch member being capable of being pushed by said first safety member to move in the lengthwise direction relative to said muzzle and said operating member.

6. The nail gun as claimed in claim 5 , wherein said operating member is formed with a guide groove that extends in the lengthwise direction, said switch member further having a guide rail that slidably engages said guide groove of said operating member.

7. The nail gun as claimed in claim 5 , wherein said gun body further includes a cap member that is mounted on said muzzle, said cap member being formed with a mounting groove that extends in the lateral direction, said operating member being movably mounted to said mounting groove of said cap member.

8. The nail gun as claimed in claim 1 , wherein said fixing member has a guide portion that is fixedly connected to said second safety member, and a limiting portion that is fixedly connected to said guide portion, said switch member further having a guide opening permitting said guide portion of said fixing member to extend therethrough, said switch member being in slidable contact with said second safety member, said limiting portion of said fixing member being in slidable contact with said switch member so as to confine said switch member.

9. The nail gun as claimed in claim 1 , wherein said second safety member is co-movable with said operation portion.
