Machinery that can universally adjust decreases sample sampling machine a little

The utility model relates to a machinery that can universally adjust decreases sample sampling machine a little, including base, the vertical support of fixing on the base, sliding connection on the support feed unit and with the cutting unit of feed unit through the pivot unit connection, the pivot unit includes a perpendicular limit, no. Two limits, no. Three limits, no. Four limits and no. Fivelimits that set up in proper order, and wherein, no. One the limit is coaxial fixed with feed unit, and no. Five the limit is fixed with the cutting unit is coaxial, a limit and no. Two limits are fixed, and no. Two limits and no. Three limits are fixed, and no. Four limits and no. Five limits are fixed, no. Four the limit can be rotated round the tie point on no. Four limits and no. Three limits. Compared with the prior art, the utility model discloses need not to adopt complicated controller, only needing under the prerequisite of the relative corner of adjusting pivot unit each limit in inadvance and feed unit's h
