The invention discloses equipment for disassembling a bearing on a rotating shaft. The equipment for disassembling the bearing on the rotating shaft comprises a rack, wherein a rotating shaft cavity with a leftward opening is formed in the rack, two sliding grooves are formed in the inner wall of the upper side and the inner wall of the lower side of the rotating shaft cavity in a communication mode, and the two sliding grooves are symmetrically distributed up and down with the center of the rotating shaft cavity as the symmetric center; and abutting plates are slidably arranged in the sliding grooves. According to the invention, the bearing on the rotating shaft can be disassembled, so that the situation that when people replace the bearing, much time is consumed to disassemble the bearing on the rotating shaft, and then the replacement speed is reduced; and moreover, damage to the rotating shaft during manual disassembling by people is avoided, and the physical output of a replacement person is reduced while the replacement speed is increased.

The invention discloses a medical biological 3D printing device. During printing, a printing material can be quickly replaced; during replacement, quick connection can be achieved only by moving a print head assembly and then matching the feeding end of the print head assembly with a discharging head of a needed printing raw material tank; when replacement of the printing raw material is needed, rapid combination with the needed printing raw material can be achieved only by electrically connecting two contacting conductive control sheets with two fixed conductive sheets at the corresponding printing raw material tank for 2-3 seconds at the same time; the matching precision is high, the replacement rate of the printing material can be greatly increased, and the printing accuracy can be improved; and in addition, through constant temperature control of the printing material, shape change after printing is reduced and the printing accuracy is improved.
