Anti-lock device for movable gear type continuously-variable transmission

The invention provides an anti-lock device for a movable gear type continuously-variable transmission, and belongs to the technical field of mechanical transmission design and manufacturing. The technology is an improved technology created on the basis of patent 200580039668.6; the patent 200580039668.6 records the function of realizing movable gear continuously-variable engaging by the sliding ofa sliding sheet combination, and thus a non-frictional-engaging continuously-variable transmission is realized. The anti-lock device comprises a movable gear unit, a unit inclination block, a small pushing rod, an inclined groove, a pushing rod, a bearing, a cam plate and other main spare parts, wherein when the movable gear is engaged with a chain gear, the bearing is rotated on the cam plate topush the pushing rod, and the moving pushing rod enables certain-angle swinging of the inclined groove, and thus the small pushing rod is pushed to enable the moving of the unit inclination block, and finally, a sliding sheet
