An energy storage type hand brake for a small trailer comprises a hand brake lever fixed to a small trailer main frame, and a brake pull rod with one end connected with a brake body. The energy storage type hand brake is characterized by further comprising a positioning piece, an energy storage spring and an actuation piece, the positioning piece is fixed to the brake pull rod and can prevent the energy storage spring from moving towards the positioning piece, one end of the actuation piece is hinged to the hand brake lever, and the other end of the actuation piece can compress the energy storage spring so that the energy storage spring can elastically deform between the positioning piece and the actuation piece. The energy storage type hand brake is mainly applied to the small trailer and can overcome the defect that due to the fact that the force arm of an existing hand brake lever is kept unchanged, incomplete braking or braking failure is caused; meanwhile, all mechanical parts adopted for the energy storage type hand brake are simple and easy to obtain, and therefore the structure is simple, and the cost of the energy storage type hand brake is low.
