When simulating the upper pointing position of the vehicle door key, the guide rod of the third guide rod cylinder 283 is elongated, driving the crank arm seat 285 and the crank arm 286 thereon to move upward, so that the crank arm 286 drives the key lever on the driver door lock 22 to rotate upward by an angle to the upper pointing position. When simulating the lower pointing position of the vehicle door key, the guide rod of the third guide rod cylinder 283 is retracted, driving the crank arm seat 285 and the crank arm 286 thereon to move downward, so that the crank arm 286 drives the key lever on the driver door lock 22 to rotate downward by an angle to the lower pointing position. When the guide rod of the third guide rod cylinder 283 remains in the initial half-stroke state, the crank arm 286 does not generate a deflection torque to the key lever on the driver door lock 22, and at this time, the key lever on the driver door lock 22 is in the middle pointing position. When the rotation stroke of the key lever of some vehicle models is relatively large, the second guide rod cylinder 282 is started to act in cooperation with the third guide rod cylinder 283 to complete the large stroke action of the key lever. Through the elongation of the guide rod of the second guide rod cylinder 282, the guide rod can drive the linkage plate 284 to move the third guide rod cylinder 283 upward as a whole, and at this time, the action of the second guide rod cylinder 282 can make the key lever have a relatively larger pointing stroke.
