Description

technical field [0001] The invention relates to a lock, in particular to a reinforced bolt. Background technique [0002] The latch is mostly composed of a latch seat, a socket seat, and an insertion rod that moves up and down or left and right along the latch seat and is inserted into the socket. The insertion rod is cylindrical, and a manual lever is provided at its rear end. Lock the plunger. Since the manual lever is fixedly connected with the insertion rod, as long as the insertion rod is rotated, the manual lever will be unlocked, and the insertion rod will break away from the locking position of the insertion plate. People only need to violently vibrate the doors and windows or use a special tool to pass through the door gap to turn the insertion rod, and then move the manual lever to unlock the manual lever, and the traditional latch is generally only equipped with a jack seat, and it is possible for people to use a little force. If the latch is destroyed, the inse...
