The invention provides an infrared controllable automatic plugging pin device. The device comprises a plugging pin body and an infrared driving circuit; the plugging pin body comprises a shell, an electromagnetic attraction and repulsion mechanism, a stroke doubling mechanism and a plugging pin assembly; the electromagnetic attraction and repulsion mechanism comprises a permanent magnet connectionring, a guide cylinder and spring tubes; the magnet connection ring is accommodated in the guide cylinder and moves axially along the guide cylinder; two ends of each spring tube are respectively connected with the magnet connection ring and the bottom of the shell; a coil is fixed in the guide cylinder; a permanent magnet is fixed to the bottom of the permanent magnet connection ring; the permanent magnet is opposite to the coil; the stroke doubling mechanism is connected with the magnet connection ring and the plugging pin assembly and performs transmission; the plugging pin assembly is fixed to the side wall of the shell; the plugging pin assembly comprises a bolt pin; and the infrared driving circuit is connected with the coil, receives external infrared signals and controls the coilto be energized or de-energized, thereby controlling the bolt pin to extend or retract. With the infrared controllable automatic plugging pin device of the invention adopted, the remote control of theplugging pin is realized. The performance of the device is reliable; the device is suitable for situations where manual operation is inconvenient or impossible; and the degree of automation of the device is high.
