The invention discloses an anti-theft kickstand of an electric bicycle, which belongs to the technical field of kickstands and comprises an I-shaped support frame mounted on two sides of a driving wheel of the electric bicycle, a mounting plate fixedly connected to the bottom end of the I-shaped support frame, a fixed pipe fixedly connected to one side surface of the mounting plate and an arc-shaped locking fastener fixedly connected to one end of the fixed pipe. The inner wall of the I-shaped supporting frame is fixedly connected with a main shaft, the outer side of the main shaft is rotationally connected with a rotating column barrel, the surface of the rotating column barrel is fixedly connected with a linkage column barrel, one end of the linkage column barrel is fixedly connected with an arc-shaped frame plate, and the interior of the arc-shaped frame plate is slidably connected with an arc-shaped toothed plate. According to the electric bicycle driving wheel locking device, the arc-shaped locking fastener, the arc-shaped frame plate and the arc-shaped toothed plate are arranged, the arc-shaped frame plate and the arc-shaped toothed plate are driven to rotate through rotation of the supporting plate, the arc-shaped toothed plate pushes and presses the abutting rod, locking plates in the arc-shaped locking fastener give an alarm mutually, and the locking function of the electric bicycle driving wheel is achieved.

本发明公开了一种电动自行车的防盗式脚撑，属于脚撑技术领域，包括安装在电动自行车驱动轮两侧的工型支撑架，固定连接在工型支撑架底端的安装板，固定连接在安装板一侧面的固定管以及固定连接在固定管一端的弧形锁扣件，工型支撑架的内壁固定连接有主轴，主轴的外侧转动连接有旋转柱筒，旋转柱筒的表面固定连接有联动柱筒，联动柱筒的一端固定连接有弧形框板，弧形框板的内部滑动连接有弧形齿板。本发明通过设置有弧形锁扣件、弧形框板和弧形齿板，利用撑板的转动带动弧形框板和弧形齿板转动，使得弧形齿板推压抵触杆，使得弧形锁扣件内部的锁扣板相互报警实现电动自行车驱动轮的锁扣功能。
