Specifically, the connector 12 includes a connection column 121 fixedly mounted in the inner cavity of the outer sleeve 11, a protruding ring 122 matched with the sealing buffer ring 2 is uniformly and integrally formed on the outer side wall of the connection column 121, a chamfer 123 is formed at the lower end of the outer side wall of the connection column 121, and a mounting hole 124 penetrates through the middle of the upper surface of the connection column 121.

The protruding ring 122 is used to increase the sealing ability of the sealing buffer tube 2 at the connection end, and the chamfer 123 is used to facilitate the sleeving of the sealing buffer tube 2 on the connection head 2.

Specifically, pneumatic control valve 13 includes with mounting hole 124 inner chamber lower extreme fixed mounting's spacing post 131, the upper end fixed mounting of spacing post 131 has sealed kicking block 132, the lower extreme of spacing post 131 runs through there is air vent 133, and air vent 133's upper end runs through sealed kicking block 132, the upper end laminating of sealed kicking block 132 has adjusting valve piece 134, adjusting valve piece 134's upper end laminating has extrusion spring 135, extrusion spring 135's upper end laminating has baffle 136, baffle 136's bottom surface excircle evenly runs through there is the reposition of redundant personnel hole 137.

Specifically, the adjusting valve plate 134 includes a circular valve plate 134-1, an airflow hole 134-2 opposite to the vent hole 133 penetrates through the middle of the circular valve plate 134-1, and a backflow hole 134-3 uniformly penetrates through the outer circle of the bottom surface of the circular valve plate 134-1.

When the piston rod 14 is pressed, the air flow enters the mounting hole 124 from the diversion hole 137, the adjusting valve plate 134 is pressed on the sealing top block 132 by the pressing spring 135, so that the air flow can only be discharged from the air flow hole 134-2, and the air flow hole 134-2 is smaller, so that when the piston rod 14 is pressed, the air flow hole 134-2 discharges slowly, the pressure in the outer sleeve 11 is larger, and the upward movement of the valve block 155 is facilitated.

When the plug 14 is rebounded by the restoring spring 16, the air flow has a faster return speed, and the adjusting valve plate 134 is pressed to lift up, so that the air flow from the return hole 134-3 can quickly enter the outer sleeve 11.

Particularly, the air suction amount adjusting assembly 15 comprises a threaded limiting rod 151, an air pressure balance hole 152 and a buffer cavity 153 arranged inside the piston rod, the outer side wall of the threaded limiting rod 151 is in threaded connection with the upper end of the piston rod 14, the air pressure balance hole 152 is arranged at the upper end of the outer side wall of the piston rod 14, a communication hole 154 is formed in the bottom surface of the buffer cavity 153, the lower end of the communication hole 154 penetrates through the lower end of the piston rod 14, a valve block 155 is sleeved inside the buffer cavity 153, the valve block 155 is matched with the bottom surface of the threaded limiting rod 151, and a pressing block 156 is fixedly arranged at the upper end of the threaded limiting rod 151.

When the piston rod 14 descends to the lowest end of the outer sleeve 11, the lower end piston of the piston rod 14 will be pressed on the upper end of the sealing tube 4, so as to block the communication hole 154, and avoid the problem that the valve block 155 moves downwards due to the self gravity because the gas can be discharged from the adsorption head 3, and the control of the suction gas amount is inaccurate.

Specifically, the upper end of the piston rod 14 extends out of the outer sleeve 11, and the upper end of the outer side wall of the piston rod 14 is uniformly and fixedly provided with the protruding columns 5.

The protruding column 5 is used for increasing the friction force of the hand, and when the threaded limiting rod 151 is rotated, the hand can hold the protruding column 5 to prevent the piston rod 14 from integrally rotating along with the rotation.

The working principle is as follows: the utility model can adjust the length of the thread limit rod 151 extending into the buffer cavity 153 by using the suction amount adjusting component 15, and when the utility model is used for picking up eggs, the press block 156 is pressed to make the piston rod 14 descend, the pressure inside the outer sleeve 11 is increased while the piston rod descends, so that the valve block 155 is pushed to move upwards, the upper end of the valve block 155 is propped against the lower end of the thread limit rod 151, in the process, the gas at the lower end of the piston rod 14 inside the outer sleeve can enter the buffer cavity 153, meanwhile, the residual gas inside the outer sleeve 11 is discharged from the adsorption head 3, when the press block 156 is loosened, the piston rod 14 can be rebounded to the original position by the restoring spring 16, and when the piston rod 14 rebounds to the original position, the gas inside the buffer cavity 153 enters the inner part of the outer sleeve 11, and the valve block 155 moves downwards in the buffer cavity 153, because the adjusting space of the buffer cavity 153 is smaller than the space between the outer sleeve 11 and the piston rod 14, when the piston rod 14 is completely rebounded by the restoring spring 16, the space between the outer sleeve 11 and the piston rod 14 cannot be completely filled by the gas in the buffer cavity 153 at the lower end of the valve block 155, so that the external gas flow can be sucked into the adjustable adsorber 1 from the adsorption head 3, the ovum can be sucked into the adsorption head 3 by the external gas flow, and the moving distance of the valve block 155 can be controlled by controlling the length of the threaded limiting rod 151 extending into the buffer cavity 153, according to the above principle, the total volume sum of the gas sucked by the adjustable adsorber 1 can be controlled, so that the ovum can be picked up and enter the position of the adsorption head 3, compared with an injector, the amount of the sucked gas does not need to be manually controlled, thereby being convenient to use and more accurate to control, and when the sealing buffer tube 2 rebounds the piston rod 14 of the sealing buffer tube 2 rapidly by the recovery spring 16, the sealing buffer tube 2 will deform due to the change of air pressure, and the sealing buffer tube 2 can generate reverse recovery to the tension, so that the sealing buffer tube 2 can generate reverse recovery to the tension to suck the ova into the adsorption head 3, and the adsorption speed is balanced, thereby avoiding the problem that the ova are lost due to unbalanced adsorption speed.
