The cut-open device of a kind of fruit and seed
Technical field
The utility model relates to a kind of biological experiment apparatus, is mainly used in botany teaching and experimentation, carries out cutting to fruit and seed, so that observe the fruit of plant and the internal structure of seed.
Background technology
In botany teaching and experimentation, need to observe the fruit of plant and the internal structure of seed, to understand its each position and tissue distribution patterns.Before observing, cutting to be carried out, by current experimental technique to fruit and seed, usual employing hand operation, this method for slitting is dangerous, is easily scratched by the hand of operating personnel, and the section out-of-flatness of fruit and seed after cutting, be unfavorable for the observation of testing the later stage.In addition, the fruit and the seed size that carry out experimental implementation differ, and diameter is between several millimeters to tens millimeters, and the diameter difference of fruit and seed is larger.The fruit larger for diameter and seed, need the cutter of large-size to carry out cutting; The fruit less for diameter and seed, need the cutter of reduced size to carry out cutting.When carrying out cutting to the fruit of different-diameter and seed, needing to prepare many cutter of different size, causing experimental cost to increase.
Summary of the invention
For solving the problem, the utility model provides the guillotine of a fruit and seed.This device can use mechanical arm to replace manual operation, thus avoids the injury that may cause operator in the cutting process to fruit and seed.In addition, carry out slitting operation by mechanical device, the cut direction of cutter is fixed, and makes the section that goes out fruit and seed cutting smooth, is easier to observe.
The technical scheme that the utility model technical solution problem adopts is: the utility model devises tooling device and a set of grip device, cutter is arranged on column by guide rail, transverse arm, fixture is arranged on the column of pedestal both sides, column is connected with pedestal, at pedestal and column built with a set of transmission device, control the folding of grip device by the rotatable transmission device of knob.Cutter is positioned at directly over fixture, and cutter can move up and down along guide rail, and the length of guide rail is equal with the stroke of cutter.Fixture is with cutter place plane for the plane of symmetry is symmetrical, and the folding of fixture is also with this plane of symmetry subtend, equidistantly movement.
The beneficial effects of the utility model are, the utility model is used for carrying out slitting operation to the fruit of plant and seed, grip device is utilized to be fixed on immediately below cutter by fruit and seed easily and accurately, guide rail can make cutter steady fall, fruit and seed can be opened from middle cutting, thus the section that acquisition one is smooth.Compared to the manual cutting to fruit and seed, the utility model can carry out slitting operation fast and accurately, improves operating efficiency.In cutting process, operating personnel do not need directly to contact experiment material and cutter, it also avoid injury to personnel.

Detailed description of the invention
In FIG, be rotated counterclockwise knob (18), driving shaft (17) drives each several part power transmission shaft left jig arm (15) and right jig arm (6) outwards to be screwed out, now fruit and seed are placed between left fixture (21) and right fixture (5), turn clockwise knob (18) again, fixture is closed and fastens fruit and seed, and prevent knob (18) from rotating lockup switch (19) closedown.
Hold the handle (3) on knife rest (2), pin peg button (1) simultaneously, promote cutter (4) downwards along guide rail (13), fruit and seed cutting are opened.Upwards lift cutter (4) by same procedure again, unclamp peg button (1), knife rest (2) is stuck on the groove surface (12) of guide rail (13) by bayonet unit.
Finally, rotate knob (18), fixture is opened, take out the good fruit of cutting and seed.
