Electric control surface lock mechanism

The embodiment of the invention discloses an electric control surface lock mechanism which drives a guide module through a motor assembly, drives a gear shaft to rotate through the guide module, and drives a trapezoidal nut to rotate, so that a trapezoidal screw rod assembly is driven to move in the axial direction, and when the trapezoidal screw rod assembly moves in the axial direction, the second support is driven to move to press the third switch assembly and send out a control surface lock locking signal, or the fourth switch assembly is pressed to send out a control surface lock unlocking signal; the trapezoidal lead screw assembly continues to move in the same direction, the first or second pressing switch assembly is pressed to cut off a circuit of the motor assembly, the motor assembly stops working, the trapezoidal lead screw assembly stops moving, and meanwhile, the first switch assembly sends out an electric control surface lock mechanism locking in-place signal, or the second pressure switch asse
