Detailed Description

The technical solution of the present invention will be described in further detail through the following embodiments.

Example 1

The present embodiment provides a telescopic sampler, as shown in fig. 1, 2, 3, 4, 5, 6 and 7, comprising an outer sleeve 5, a support holder 1 for fixing the outer sleeve 5, and an inner sleeve 4 rotatably disposed inside the outer sleeve 5. A plurality of sampling holes 6 are correspondingly arranged on the side wall of the outer sleeve 5 and the side wall of the inner sleeve 4.

The bottom of the inner sleeve 4 is communicated with a suction pipe 7, and the top of the inner sleeve 4 is connected with a cylinder 2 for pushing the inner sleeve 4 to rotate.

In this embodiment, the sampling holes 6 are arranged in sequence at equal intervals.

Specifically, as shown in fig. 2 and 3, the cannula sampler is schematically shown in a sampling state. During the sample, interior sleeve pipe is rotatory in the outer tube for set up a plurality of thief holes on interior sleeve pipe and set up a plurality of thief holes one-to-one on the outer tube, thereby make the sample from the thief hole department that link up flow into in the inner tube, realize the sampling operation.
