The invention relates to the field of lifting devices, in particular to a safe support for a hydraulic lifting platform. The safe support comprises a telescopic sheath and a telescopic rod, wherein the telescopic sheath comprises a sheath body, an electromagnet, a sliding iron core and a reset spring, the cross section of the sheath body is U-shaped and surrounds the telescopic rod, and the upper portion of the sheath body is connected with the lifting platform; the electromagnet is located on the lower portion of the sheath body, the end, close to the telescopic rod, of the sliding iron core is V-shaped, and the sliding iron core is located on the left side of the electromagnet; one end of the reset spring is connected with the electromagnet, the other end of the reset spring is connected with the sliding iron core, the cross section of the telescopic rod is inverse-T-shaped, the lower end of the telescopic rod is connected with a base of the hydraulic lifting platform, the telescopic rod is matched with the telescopic sheath, braking teeth are arranged on the right side of the telescopic rod, and the sliding iron core can be inserted in the braking teeth to prevent the telescopic sheath from getting out of control to slide down. Self-locking of the safe support can be achieved after the platform is stopped, accidents caused by falling of objects on the platform when a lift breaks down are avoided, and the hydraulic lifting platform is made safer and more reliable.
