The adoption of the transmission of a plurality of connecting rods can ensure that the cutter can ensure the centering performance of cutting and sampling and the thickness and the diameter of a cut sample by taking the center of the rotating shaft of the base as a cutting center in the process of swinging and cutting. The single-rod rigid connecting ring is selected, so that the rigid contact abrasion between the connecting ring at the top end of the swing rod and the rotating motor is reduced, and the situation that the excessive force is applied to the rotating shaft to cause the deviation in the direction perpendicular to the rotating shaft of the rotating motor and influence the shape of a cut sample is avoided.
The number of the transmission rods is 2 or 3.
The middle part of the rotating motor is sleeved with a fixed hoop frame, and the hoop frame is rotatably connected with the horizontal rotating shaft.
The sampling cutter is a hemispherical or semi-ellipsoidal bowl-shaped cutting cutter.
Compared with the prior art, the beneficial effects of the invention are embodied in the following aspects:
(1) the whole cutter unit is driven to swing through the swing unit, and then the two motion tracks are combined through the downward precession of the cutter unit, so that a micro sample is cut on the device to be sampled, and the device has a compact structure, is convenient to mount, is practical and effective, and has reliable performance;
(2) the connecting unit is formed by the transmission rods, so that the centering performance of the cutter during cutting is guaranteed, the blade part of the cutter is guaranteed to effectively cut a sample, and the phenomenon of cutter clamping during cutting is prevented; meanwhile, the stability of the size, shape and thickness of the sample is ensured, and the cut surface of the sample taken out is smooth.
