Locking device on firing pin of double-air-cylinder electric nail gun

Abstract

The invention discloses a locking device on a firing pin of a double-air-cylinder electric nail gun. The locking device comprises a gear case, wherein a connector is arranged on the upper right of thegear case; a moving hole which communicates with the internal space of the connector is formed in the left side wall of the connector; a first air cylinder is connected with the connector; a second air cylinder which communicates with the internal space of the gear case is arranged on the right side wall of the gear case and positioned right below the first air cylinder; a first piston matched with the first air cylinder is arranged in the first air cylinder; a second piston matched with the second air cylinder is arranged in the second air cylinder; the firing pin is connected with the firstpiston; the front part of the firing pin penetrates to the outside world through the moving hole; a plurality of clamping grooves are formed in the front part, which penetrates to the outside world,of the firing pin; an eccentric shaft seat is arranged in the gear case; and an eccentric shaft is arranged on one side of the eccentric shaft seat. The locking device on the firing pin of the double-air-cylinder electric nail gun has the beneficial effect that under the circumstance that the internal air pressure of the double-air-cylinder electric nail gun is enough, a positioning sheet can be automatically opened and the automatic nailing effect can be achieved.

Description

technical field [0001] The invention relates to a locking device on a striker of a double-cylinder electric nail gun. Background technique [0002] When the double-cylinder electric nail gun is not in use, the firing pin assembly will be locked through the positioning piece, and when in use, the air pressure in the cylinder will continue to increase. At this time, the staff only needs to pull the positioning piece by external force When it is detached from the striker assembly, the striker can be pushed out by the increased air pressure, so that the nail can be driven out through the striker, but this nailing method cannot realize automatic nailing, and the staff needs to actively open the positioning piece after each time the air pressure is sufficient. Seem extremely troublesome, have a strong impact on nailing efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a locking device on the striker of the d...
