The invention discloses a universal double-brake trundle support. The universal double-brake trundle support comprises a double-fork support and a fixing base. A brake ring is arranged on the double-fork support. A ring of tooth space is formed in the brake ring. The brake ring and the fixing base are connected through a rivet. A rotatable stepping crank is arranged on the double-fork support. A folding leaf spring is hinged to the double-fork support and comprises an upper metal sheet and a lower metal sheet, wherein the tail end of the upper metal sheet and the tail end of the lower metal sheet are connected. The two sides of the lower metal sheet are provided with two brake insertion rods pointing to the tooth space respectively. A curved plate is arranged at the upper portion of the upper metal sheet in an extending manner. According to the universal double-brake trundle support, during braking, the stepping crank is rotated manually, and the brake insertion rods extend into the tooth space to limit rotation of the double-fork support; the curved plate presses a rolling wheel to prevent the rolling wheel from rotating, so that simultaneous lock of the rolling wheel and steering is achieved; and the stability is high.
