During operation, the fixed shell 20 is fixed on the probe body 1 and can move with the probe body 1. When using the probe body 1, first ensure that the fixed shell 20 is located in front of the moving path of the probe body 1, and then move the probe body 1 to inspect the subject. It is only necessary to continuously rotate the rotating block 33 on the cover plate 32, so that the coupling agent can flow out of the delivery tube 21 and be applied to the subject's skin. The rotating block 33 is connected to the threaded rod 31. Rotating the rotating block 33 will drive the threaded rod 31 to rotate in the cover plate 32, and the moving block 30 threadedly connected on the threaded rod 31 will continuously move upward. The moving block 30 is fixed with an abutment block 29 and abuts with the connecting block 28 through the abutment block 29. At this time, the connecting block 28 can be driven to move synchronously through the abutment block 29. When the cover plate 32 is rotated to open the inside of the installation groove 47, the abutment block 29 can also be smoothly separated from the connection block 28. When the connection block 28 moves, the extrusion plate 25 will continuously squeeze the hose 23, thereby squeezing out the coupling agent inside the hose 23 and delivering it through the delivery pipe 21. The fixing plate 26 is fixed with a connection spring 27, which can provide support for the fixing plate 26 and ensure the contact between the extrusion plate 25 and the hose 23, so that the extrusion operation can be carried out smoothly.

When working, when the probe body 1 is used, the probe body 1 needs to be inverted first. At this time, under the action of gravity, the counterweight 38 will slide downward inside the movable groove 41, and the rack 40 is meshed with the counterweight through the connecting rod 37. The weight blocks 38 are connected together, so the rack 40 will also slide in the movable groove 41. Since the rack 40 is meshed with the gear 36, the rack 40 will drive the gear 36 to rotate when it moves. The gear 36 is connected to the bottom end of the baffle 35, and the baffle 35 will rotate a certain angle, so that the previously blocked delivery tube 21 can be exposed. At this time, the coupling agent in the delivery tube 21 can be smoothly applied to the skin of the subject. A slot 34 is provided on the fixed shell 20, and the size of the slot 34 is adapted to the baffle 35, so that the baffle 35 can fit together with the inner wall of the slot 34 when closed, so as to improve the shielding effect of the delivery tube 21.
