The invention discloses a double-trundle brake device for a handcart. The double-trundle brake device comprises an installing bottom plate, a brake treading piece and a transmission brake rod; two brake plates are arranged at the two ends of the transmission brake rod respectively; one end of the brake treading piece is connected with the transmission brake rod and provided with a pull rod parallel to the transmission brake rod, and one end of the pull rod is connected with the installing bottom plate through a tension spring; the side face of a reset treading piece extends downwards to form a reset frame, and a self-locking hole for penetrating the pull rod is formed in the reset frame and internally provided with a triangular positioning block corresponding to the pull rod. By means of mode, a user can tread the brake treading piece to turn over the transmission brake rod and the brake plates downwards so as to brake and fix trundles, and before the handcart is pushed, one end of the pull rod slides onto the triangular positioning block through the reset treading piece for unlocking.
