[0038] As Figure 2As shown, a represents the off position, b represents the ignition position, c represents the lock faucet position, the first and second pull wire positions are not marked. When the initial state of the ignition lock is in the off position and the first pull wire is to be unlocked, rotate the knob counterclockwise, the shaft rotates, because the transmission part does not contact the first side of the lock tongue bracket in the rotation stroke (i.e. the first and second fan surfaces do not contact the first side), so rotating the shaft does not move the lock tongue bracket, the rotating block rotates counterclockwise with the shaft, at this time the rotating block rotates to drive the first pull wire slider to slide, the first pull wire slider drives the first pull wire to move, thereby driving the seat cushion lock or fuel tank lock adapted to the first pull wire to be unlocked, release the knob, the first pull wire slider resets under the action of the first pull wire spring, Figure 9 As shown, the position of the positioning block in the off position, the lock cylinder sleeve rotates with the shaft, and the positioning block is below the first rectangular block after the lock cylinder sleeve rotates, and this section of the positioning block after the lock cylinder sleeve rotates is the stroke of the first pull wire position; when the initial state of the ignition lock is in the off position and the ignition is to be started, rotate the knob clockwise, the shaft also rotates clockwise, because the second side of the lock tongue bracket has a circular surface for the smooth rotation of the transmission part, so the shaft does not move the lock tongue bracket, the rotor in the rotor switch rotates to the ignition position under the action of the shaft, and the power supply is turned on, Figure 9 As shown, the position of the positioning block in the off position, the lock cylinder sleeve rotates with the shaft, and the positioning block is below the second rectangular block after the lock cylinder sleeve rotates, and this section of the positioning block after the lock cylinder sleeve rotates is the stroke of the second pull wire position; when the initial state of the ignition lock is in the off position and the faucet is to be locked, press down the knob, the shaft moves towards the lock tongue bracket, then rotate the knob counterclockwise to the lock faucet position, the second fan surface of the transmission part of the shaft abuts against the first inclined surface in the first side, the lock tongue bracket moves under the action of the shaft, thereby pushing the lock tongue to lock the faucet, release the knob, the shaft resets under the action of the second reset spring, because when the knob is pressed down, the linkage part of the shaft enters the circular tube of the rotor and is separated from the rotor, so the lock faucet will not affect the rotor switch, Figure 9 As shown, the position of the positioning block in the off position, the lock cylinder sleeve rotates with the shaft, and the positioning block is above the first rectangular block after the lock cylinder sleeve rotates, and this section of the positioning block after the lock cylinder sleeve rotates is the stroke of the lock faucet; when the initial state of the ignition lock is in the off position and the second pull wire is to be unlocked, press down the knob, the shaft moves towards the lock head bracket, rotate the knob clockwise, the shaft also rotates clockwise, because the second side of the lock tongue bracket has a circular surface for the smooth rotation of the transmission part, so the shaft does not move the lock tongue bracket, the rotating block rotates clockwise with the shaft, the depressed rotating block can abut against the second pull wire slider and drive the second pull wire slider, thereby driving the seat cushion lock or fuel tank lock adapted to the second pull wire to be unlocked, release the knob, the second pull wire slider resets under the action of the second pull wire spring, because when the knob is pressed down, the linkage part of the shaft enters the circular tube of the rotor and is separated from the rotor, so unlocking the second pull wire will not affect the rotor switch, Figure 9The image shows the position of the positioning block when the engine is off. After pressing down, the lock cylinder sleeve rotates with the shaft, and the positioning block is above the second rectangular block. The distance that the positioning block travels after the lock cylinder sleeve is pressed down and rotates is the travel distance of the second pull cable. By setting the positioning block and the second rectangular block, after the knob is turned, the positioning block abuts against the second rectangular block to prevent the lock cylinder sleeve from returning to its original position. Only after the second pull cable spring returns to its original position will the second return spring cause the shaft to return to its original position.

[0039] When the ignition lock is in the lock handle position, if criminals shake the vehicle handle from side to side, causing the handle to hit the latch and the latch to hit the pivot shaft, the reinforcing plate supports the pivot shaft, protecting it and preventing it from breaking, thus achieving an anti-theft effect.
