At the same time, the lower sliding rack 9 drives the insulating separation head 17 to slide to the right and plug it between the two spring copper sheets 18. When the two spring copper sheets 18 are in contact, the vehicle circuit is in a connected state. The insulating separation head 17 insulates and separates the two spring copper sheets 18 to achieve the circuit disconnection operation of the vehicle.

[0037] The upper end of the steel cable 10 passes through the installation box 11 and the two first guide columns 12 in sequence and is fixed in the annular groove provided in the middle of the transmission gear 6. Then, when the transmission gear 6 rotates counterclockwise, the lower end of the steel cable 10 drives the front leg locking tongue to move down under the action of elastic force. A number of corresponding insertion holes are evenly provided on the outer edge of the wheel hub brake disc position under the front leg of the vehicle. The front leg locking tongue moves down and is inserted into the corresponding insertion holes of the brake disc to lock the front leg of the vehicle. The transmission gear 6 can lock the handlebars and front legs of the vehicle in sequence and cut off the circuit through the upper sliding rack 8, the steel cable 10 and the lower sliding rack 9, thereby realizing the synchronous locking of the two-wheeled, three-wheeled and four-wheeled electric vehicles. When the transmission gear 6 is driven by the key to rotate ninety degrees clockwise, that is, to reset the transmission gear 6, the upper sliding rack 8, the lower sliding rack 9 and the steel cable 10 are synchronously driven to reset and the vehicle's chain lock can be unlocked.
