The working principle of the invention is as follows:

when collecting saliva, inserting the collecting component 2 into the oral cavity to collect saliva, and collecting the saliva; the collection assembly 2 is driven to contract towards the inside of the support 1 through the handle on the supporting rod 24, the rack 62 drives the collection assembly 2 to rotate in the descending process through the one-way gear 61 in the contraction process, the collection assembly 2 abuts against the pinch roller 51 in the descending process of the collection assembly 2, the pinch roller 51 descends along with the collection assembly 2 to extrude the collection assembly 2 which rotates and descends, and saliva on the collection sponge sleeve 23 enters the collection pipe 41 through the transfer ring 22; the transmission component 4 contracts towards the inside of the bracket 1 along with the collection component 2, in the contraction process, the touch rod 42 on the collection pipe 41 descends along with the contact rod, the touch rod 42 initially descends, the driving sliding rods 434 on two sides of the rotating sleeve 43 enter the leading-in section 441, when the touch rod 42 touches the limiting rod 447, the rotating component 6 of the touch rod 43 slides into the suction section 442 due to the blocking of the one-way lock 445, so that the position of the rotating sleeve 43 rotates, the first communicating hole 416 is communicated with the third communicating hole 432, the second communicating hole 417 is staggered with the fourth communicating hole 433, and meanwhile, the touch rod 42 touches the piston 414 to slide towards the inside of the inner sleeve 412, so that saliva in the collection pipe 41 enters the inside of the inner sleeve 412; when the collecting tube 41 descends to the lowest end, the second central hole 435 slides into the transition section 444, slides into the discharging section 443 under the action of elasticity, then the collecting tube 41 ascends, the driving sliding rod 434 drives the rotating sleeve 43 to rotate, so that the second communicating hole 417 is communicated with the fourth communicating hole 433, the first communicating hole 416 is staggered with the third communicating hole 432, and the piston 414 is restored to the initial state under the action of elasticity, thereby discharging saliva at the bottom of the inner sleeve 412. When piston 414 inhales saliva to endotheca 412 inside, the inside saliva of collecting pipe 41 reduces this moment, because collecting pipe 41 and collection subassembly 2 inside intercommunication, consequently whole collection subassembly 2 is inside can appear the pressure and become down, so and then can promote the saliva that extrudes from collecting sponge cover 23 to get into transfer ring 22, get into collection subassembly 2 in the saliva increase be convenient for transfer module 4 discharge work, collection subassembly 2 and transfer module 4 both promote each other.
