Detailed Description
In order to clearly illustrate the technical features of the present solution, the present solution is explained below by way of specific embodiments.
As shown in figure 1, the utility model comprises a collecting pipe 1, a sealing cover 2 is buckled at the pipe orifice of the collecting pipe 1, and the pipe cavity of the collecting pipe 1 is separated into a left purifying chamber 4 and a right sample storage chamber 5 through a filter screen 3. A through hole for inserting a rubber head dropper is arranged on the sealing cover 2 opposite to the left purification chamber 4, and a sealing plug 14 is plugged in the through hole. Be equipped with sample spoon 6 in right sample storage chamber 5, sample spoon 6 is connected with connecting rod 7, and sealed lid 2 is worn out and is connected with handle 10 to the upper end of connecting rod 7, and a plurality of spoilers 8 of rigid coupling on connecting rod 7.
