Detailed Description
The present invention will be described in detail and specifically with reference to the following examples so as to provide a better understanding of the present invention, but the following examples do not limit the scope of the present invention.
Example 1
The embodiment discloses a hierarchical formula is forced and is got ware, including pressure head 1, pipette 2, inflating pipe 3 and outer tube 4. The air inflating pipe 3 is sleeved at the middle upper part of the liquid suction pipe 2, and the top of the air inflating pipe 3 is fixedly connected with the outer sleeve 4.
The middle position of the pressing head 1 is provided with a liquid outlet pipe 11, the bottom of the pressing head is provided with a piston 12, the side of the pressing head is provided with a clamping block 13, the top of the liquid suction pipe 2 is inserted into the liquid outlet pipe 11, and the pressing head 1 is connected with the top of the liquid suction pipe 2 in a sliding mode.
The bottom of the inflating pipe 3 is provided with an inflating opening 31, the inside of the inflating pipe is provided with a return spring 32, the top of the inflating pipe is provided with a limiting bayonet 33, the return spring 32 is arranged at the bottom of the piston 12, and the limiting bayonet 33 is matched with the clamping block 13 and limits the distance of the clamping block 13 moving up and down.
