Electric bolt

The invention discloses an electric bolt. The electric bolt comprises a rack, a driving mechanism, a lead screw, an end cam, a detection block, a proximity switch, a sliding sleeve and a bolt, wherein the driving mechanism is fixed on the rack, the output end of the driving mechanism is connected with the lead screw, the end cam is coaxially fixed on the lead screw, the detection block is movably arranged on the rack in the radial direction of the lead screw, the detection end of the detection block is matched with the end face of the end face cam, the proximity switch can be movably fixed to the rack in the radial direction of the lead screw, the sliding sleeve is fixed to the end, away from the driving mechanism, of the lead screw, and the bolt is fixed to one end of the sliding sleeve. The electric bolt has the advantages that the axial size of the electric bolt is reduced, the structure is more compact, the stroke adjustment of the electric bolt is realized, and the applicability is higher; and meanwhile,
