The invention relates to the technical field of deep sea rock core sampling equipment, in particular to deep sea ore deposit surface rock core in-situ crushing equipment which comprises a sealing box and a hydraulic driving assembly fixed to the upper portion of the sealing box, a plurality of drill bit connecting rods are arranged in the sealing box, and a threaded hole is formed in the top end face of each drill bit connecting rod; a threaded connecting rod is arranged on the bottom end face of the sealing box, a translation clamping mechanism used for driving the drill bit connecting rod to move horizontally is arranged in the sealing box, and a clamping rotating mechanism used for driving the drill bit connecting rod to be connected with the crushing drill bit is arranged on the lower portion in the sealing box. The length of the crushing drill bit can be increased at the crushing position of the surface layer of the deep sea ore deposit, so that the depth of rock core in-situ crushing of the crushing dri
