[0035] working principle:

[0036] When the optical fiber main body 11 is pulled, it drives the rolling shaft 24 to rotate, and at the same time drives the connecting rod 25 and the first bevel gear 26 to rotate, and through the meshing effect of the first bevel gear 26 and the second bevel gear 27, the Drive the second bevel gear 27 and the connecting sleeve 28 to rotate, and through the threaded connection between the second bevel gear 27 and the two-way screw rod 30, the two-way screw rod 30 can be driven to reciprocate left and right, thereby driving the connecting block 31 and the sealing plug 33 to reciprocate, when the two-way screw rod 30, the connecting block 31 and the sealing plug 33 move to the right, the fourth sealing valve 37 is opened, and the third spring 39 is squeezed and deformed, so that the The condensate inside the condensation tank 3 is squeezed, and at the same time, the second sealing valve 13 is squeezed to drive the second sealing valve 13 to rotate and open, and the second spring 14 is squeezed and deformed, pushing the condensate inside the cooling tank 10 to squeeze out. Press the first sealing valve 5 so that the first sealing valve 5 is opened and the condensate in the cooling tank 10 enters the inside of the condensing tank 3 through the liquid outlet pipe 4.
