Abstract
The invention discloses a leaf picking blade for botany experiments, and solves the problems of nonstandard cutting size, poor safety, inconvenience in use and the like of an existing leaf picking blade for botany experiments. The leaf picking blade is technically characterized by comprising a blade with a screw hole, a bolt and a stud, wherein internal threads and external threads are formed in the bolt simultaneously; the external threads of the bolt are screwed with the internal threads of the screw hole of the blade; the internal threads of the bolt are screwed with the external threads of the stud; and the blade is limited on the stud by being screwed onto the bolt of the screw hole. The leaf picking blade is skillful in design, and has the advantages of simplicity in operation method, convenience in use and the like.
Description
Technical field
The present invention relates to a kind of experimental tool, relate in particular to a kind of Botany Experiment with getting the leaf blade.Be mainly used in conveniently cutting the plant sample as microexamination.
Background technology
At botanical lab; usually can choose some plant roots, stem, leaf does section and carries out microscopic examination; but when cutting plant; usually the problem that some are difficult for cutting can occur; the tissue of some plants of microscopic examination has higher requirement to cutting of plant; usually will be very thin one section, the normal employing in laboratory be cut two blade foldeds.But this method usually can cause plant tissue fracture, uneasy congruent problem.Apparent, two blades of simultaneously taking are cut the requirement of experimental implementation level too high, and cutting effect is usually undesirable, need the repeated multiple times satisfied observation sample that cut to obtain.For comparatively precious sample, the experimental material limited amount, allow hardly misoperation, and strengthened the experiment difficulty.Need a kind of blade that conveniently cuts plant sample for this reason.
Summary of the invention
The purpose of this invention is to provide a kind of Botany Experiment with getting the leaf blade, solved existing Botany Experiment with getting the problems such as leaf blade cuts size is lack of standardization, poor stability, use inconvenience.Its structural design is ingenious, have the advantages such as method of operating is simple, easy to use.
The technical solution adopted in the present invention is: Botany Experiment comprises blade, bolt, the double-screw bolt with screw with getting the leaf blade; Bolt has internal thread and external thread simultaneously, and the internal thread of the external thread of bolt and blade screw is screwed, and the internal thread of bolt and the external thread of double-screw bolt are screwed; Blade is spacing on double-screw bolt by the bolt that screws in screw.
One end of described double-screw bolt is fixed with Handheld Division.
The advantage that the present invention has and positive technique effect are: two blades are spacing on double-screw bolt securely by the bolt with inside and outside two screw threads, guaranteed that testing crew is cutting the handling safety of test sample.But, by the distance between double-screw bolt and two blades of bolt free adjustment, can cut the experiment material of any width.Using method is simple, and easy operating has improved the efficiency of experiment.Bolt has internal thread and external thread simultaneously, and blade is spacing on double-screw bolt by the bolt that screws in screw, after unscrewing bolt, by the rotation double-screw bolt, gets final product the distance between adjustable blade, after regulating, bolt is screwed, and blade can be fixed, extremely easy to use.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is surface structure schematic diagram of the present invention;
Fig. 2 is plan structure schematic diagram of the present invention.
Sequence number explanation in figure: 1 double-screw bolt, 2 blades, 3 Handheld Divisions, 4 bolts.
Embodiment
Describe concrete structure of the present invention in detail according to Fig. 1～2.This Botany Experiment comprises a pair of blade with two screws 2, the two pairs of bolts 4, two pairs of double-screw bolts 1 with getting the leaf blade.Wherein, bolt 4 has internal thread and external thread simultaneously, and the internal thread of the external thread of bolt 4 and blade 2 screws is screwed, and the external thread of the internal thread of bolt 4 and double-screw bolt 1 is screwed; Blade 2 is spacing on double-screw bolt 1 by the bolt 4 that screws in screw.For ease of rotation double-screw bolt 1, at an end of double-screw bolt 1, be fixed with Handheld Division 3.During use, when needs regulate between two blades 2 apart from the time, the bolt on one of them blade is unscrewed, to guarantee two blades, can not move with the rotation of double-screw bolt simultaneously.Then rotate double-screw bolt, adjustable blade precession or back-out.Again bolt is screwed and blade can be fixed in blade after regulating, easy to operate.Also can according to actual needs, freely increase and decrease the quantity of double-screw bolt and blade.
