Detailed Description
The utility model will be further described in detail with reference to the following specific examples:
example 1:
the multi-sample sampling device as shown in fig. 1 to 5 comprises a moving frame and a bottom frame provided with two upright posts 1; the movable frame comprises a strip-shaped plate 2 and eight cup frames 3 equidistantly arranged on the strip-shaped plate 2, sampling cups 4 are arranged in the cup frames 3, openings are formed in the positions, corresponding to the cup frames 3, of the strip-shaped plate 2, the sampling cups 4 are taken and placed from the openings, three clamping grooves 5 which are longitudinally arranged are symmetrically formed in the column walls of the two upright columns 1 on the opposite sides, and the two ends of the strip-shaped plate 2 are clamped into the clamping grooves 5, so that the movable frame is arranged between the two upright columns 1 of the underframe; the locating rack is symmetrically arranged above the two stand columns 1 and comprises a locating block and a locating rod 6, the top of the locating rod 6 is fixedly connected with the lower surface of the locating block, the bottom of the locating rod 6 extends into a locating hole formed in the upper surface of the stand column 1, and a compression spring 7 for connecting the lower surface of the locating block and the upper surface of the stand column 1 is sleeved on the locating rod 6.
