A pneumatic nail gun, relating to the field of power tools, including a body and nail feeding device, the body including cylinder and drive assemblies, the cylinder assembly including a first and second cylinder, striker, and interlocking structure, the first cylinder including a cylinder housing, first piston, and first chamber, the first piston having front and rear limit positions, the second cylinder including a barrel, second piston, and second chamber, the striker having initial and nail-striking positions which are synchronous to initial nail-striking positions of the second piston, an intake gap forms between the cylinder housing and first position at the front limit position so that external air flows into the first cylinder first chamber via the intake gap. Air intake into the first chamber is realized without forming holes on the sidewall of the cylinder housing, with improved intake efficiency of the first chamber and nail-driving performance.

Pneumatic nail gun

A bidirectionally rotatable mechanism, a bidirectional sander, and a bidirectional cleaner; the mechanism including an actuator, an inner and an outer shaft, the inner and outer shafts being actuated to rotate by the actuator, the outer shaft being sleeved outside the inner shaft; a speed reducer is arranged between an output shaft of the actuator and the inner shaft; two ends of the speed reducer are in transmission connection with the output shaft and the inner shaft, respectively; a first gear is arranged on an outer peripheral surface of the inner shaft; an outer transmission assembly in transmission connection with the outer shaft is arranged outside the inner shaft, the outer transmission assembly including a support element, an upper planetary carrier, a planetary gear meshing with the first gear, and a lower planetary carrier connected to the outer shaft, the planetary gear between the upper and the lower planetary carrier.
