after the movable plate 12 and the placing plate 11 are reset, the movable plate 12 and the placing plate 11 are placed on the lapping table 14 and clamped by the lapping table 14, so that the placing plate 11 can only move upwards, the movable plate 12 can only move along the direction of the sliding groove 13, a magnet is arranged between the movable plate 12 and the bottom end of the sliding groove 13, thus initially limiting the movable plate 12 and preventing the movable plate 12 from easily shifting, then a motor and a water pump are synchronously started, the motor drives the driving bevel gear 29 to rotate so as to drive the first bevel gear to rotate, the first bevel gear drives the first chain to drive and operate through the first bevel gear and the second bevel gear so as to drive all the inner wall brushes 18 to rotate, the inner wall of the puncture needle 33 is scrubbed, the water pump conveys disinfectant to a cavity in the inner wall brush 18, the disinfectant is sprayed out from the second spray hole so as to scrub the inner wall brush 18, the sprayed disinfectant flows out from a side hole at the top end of the puncture needle 33, meanwhile, the driving bevel gear 29 drives the driven bevel gear 30 to rotate through the second belt transmission, the driven bevel gear 30 on the left side drives the driven bevel gear 30 on the right side to rotate through the first belt transmission, the driven bevel gear 30 drives the first chain transmission to rotate through the third bevel gear and the fourth bevel gear, so that all the mounting posts 19 are driven to rotate, the mounting posts 19 firstly stir the rectangular pyramid 28 to enable the rectangular pyramid 28 to rise, the limiting spring 27 is compressed, the third pull rope 26 is loosened, the rectangular pyramid 28 is continuously jacked up by the mounting posts 19 before the mounting posts 19 stably rotate, after the mounting posts 19 stably and rapidly rotate, the moving block 25 pulls in the third pull rope 26 under the centrifugal action to pull up the rectangular pyramid 28, so that the rectangular pyramid 28 is separated from the mounting posts 19, the mounting plate rotates to drive the mounting posts 19 to rotate, and then the outer wall hairbrush 21 and the spray pipe 20 are driven to rotate along the puncture needle 33, in the process of rotation, the planetary gear 22 is meshed with the inner gear ring 23 to rotate, so that the outer wall hairbrush 21 is driven to rotate, and the water pump conveys disinfectant into the spray pipe 20, so that the outer wall of the puncture needle 33 is cleaned, and as the driving bevel gear 29 is positioned at the left side of the first bevel gear, the placing plate 11 is different in jumping in the driving process, and the moving plate 12 is limited by the existence of the magnet, so that the moving plate 12 is prevented from continuously jumping in the cleaning process;

after the cleaning is finished, the motor and the water pump are turned off, the motor is stopped after rotating for an integer number of circles, the rotation of the inner wall brush 18 and the mounting column 19 gradually slows down until the motor is stopped, in the process, the centrifugal force on the turntable 24 gradually decreases, the moving block 25 gradually resets, the rectangular pyramid 28 descends so as to limit the mounting column 19, after the mounting column 19 is stopped, the rectangular pyramid 28 descends so as to limit the mounting column 19 again, the outer wall brush 21 and the spray pipe 20 are positioned on the front side and the rear side of the inner wall brush 18 again, so that when the end cover 2 is opened, the outer wall brush 21 or the spray pipe 33 cannot interfere with the outer wall brush 21 or the spray pipe 20, finally, the end cover 2 is opened again, the moving plate 12 and the placing plate 11 ascend again, and the upper end of the spray pipe 33 penetrates out from the guide hole 32 so as to take out the cleaned puncture needle 33.

In embodiment 2, since the puncture needles 33 have different types and different lengths, the repeated puncture needles 33 are between 15 CM and 20CM, in order to make the device more applicable, the placement plate 11 is provided with a plurality of steps, the steps are gradually increased from outside to inside, and the guide holes 32 on the guide plate 31 are divided into a plurality of areas corresponding to the puncture needles 33 with different lengths according to the different steps, as shown in the drawing (the height is more obvious in the drawing, and the size is larger).

The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements falling within the spirit and principles of the invention.
