The invention discloses a pressure switch locking and releasing device suitable for ground test. The pressure switch locking and releasing device comprises a base (1) and a locking and releasing mechanism (2), wherein the locking and releasing mechanism (2) comprises a pressure lever bracket (21), a handle (22), a crank rocker arm (23), a pressure lever (24) and a round sleeve (26), the pressure lever bracket (21) is connected with the base (1) through mounting holes in the side wall, and is connected with the head of the handle (22) through a lug; the crank rocker arm (23) is movably connected with the head of the handle (22) and the upper end of the pressure lever (24); the lower end of the pressure lever (24) penetrates through a mounting hole of a bottom flat plate of the pressure lever bracket (21) and the round sleeve (26) below the pressure lever (24); the pressure switch (3) is fixedly arranged below the locking and releasing mechanism (2). According to the pressure switch locking and releasing device disclosed by the invention, during the ground test, the simulation for the locking and releasing process of an actual pressure switch is realized, and the locking and releasing work depending on manual operation is converted into an operating instruction with standardization and generalization, and higher adaptability is realized.
