The invention relates to a rapid synchronous belt replacing mechanism which is characterized in that the rapid synchronous belt replacing mechanism comprises a left side plate, a right side plate and a synchronous belt mechanism, a space is formed between the left side plate and the right side plate, the synchronous belt mechanism is installed in the space, and adjusting mechanisms are arranged on the left side plate and the right side plate; the adjusting mechanism adjusts the relative distance between the left side plate and the right side plate, the synchronous belt mechanism comprises a driver, a main shaft, a main belt wheel, a synchronous belt and belt wheels, the main belt wheel and the belt wheels are installed on the front portion and the rear portion of the space between the left side plate and the right side plate, and the output end of the driver is connected with the main belt wheel and drives the main belt wheel to rotate. Wherein the synchronous belt is sleeved on the driving belt wheel and the driven belt wheel to form a closed transmission mechanism, the belt wheels are arranged on the main shaft, two ends of the main shaft are respectively arranged on the left side plate and the right side plate, the main shaft is divided into two sections, and the two sections of the main shaft are fixedly connected through the main shaft connecting piece. According to the rapid belt replacing mechanism, the structure is simple, through reasonable design, reasonable design of the synchronous belt and design of the main shaft into two sections, a new synchronous belt can be replaced only by loosening a screw on a connecting piece of the main shaft during replacement, and the replacing speed is greatly increased.

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.

The invention discloses a reminder device convenient for replacing warning signs for power supply construction, including the base, a vertical lifting column is fixedly installed on the upper surfaceof the base, and a lifting device is installed in the lifting column, a threaded rod is driven to rotate by opening a driving motor, so that the threaded connecting block moves linearly along the threaded rod, as such, the push rod push and adjusts the height of the connecting plate, the range of warning signs on the connection board is increased, to facilitate the replacement of damaged or otherwarning signs by staff, Increased rate of replacement, the buffer device can improve the protection of the arc cover and the shielding plate in rainy and snowy weather, as the arc cover and the shieldplate are impacted by the rain and snow, the shield plate is moved downward so that the distance between the shield plate and the fixing plate is reduced, and the two slide blocks are separated alongthe slide rail under the push of the rotating lever, and the springs on the slide rail are compressed at the same time, thereby cushioning, damping and protecting the arc cover and the shield plate.
