Disclosed is a compression spring release type hijack-proof device. By means of the compression spring release type hijack-proof device, the problems that type selection of a motor serving as a power source is difficult and too many transmission assemblies are arranged, so that the weight of the complete machine of an existing hijack-proof device is high, the oil consumption is increased are solved. The compression spring release type hijack-proof device comprises an upper crossbeam assembly, a lower crossbeam assembly and a transmission mechanism assembly. According to the technical points, the transmission mechanism assembly adopts spring release assemblies which store energy by pressing springs and then release the energy as power sources; a micro-motor shaft rotatably pulls brake cables fixed together on a concentrator to move synchronously, and rotary cams fixed to cam shafts are driven to rotate around the shafts relative to a fixed cam on a thick vertical plate; all the cam shafts move in the axial direction simultaneously to retreat from the restraints of upper pressure-bearing seats to the compression springs; the springs release the stored energy to drive the upper pressure-bearing seats to pop upwards, so that the upper crossbeam assembly hinged to the upper pressure-bearing seats is lifted evenly. Compared with like products, the compression spring release type hijack-proof device is simple in structure; raw materials are saved; the weight of the complete machine is significantly reduced; the manufacturing cost is reduced; energy is saved; lifting is more stable; protection is rapid; the hijack-proof property is improved effectively.
