Description

Landscape plant specimen holder and connection structure thereof

Technical Field

The invention relates to the field of specimen collection and production, in particular to a garden plant specimen holder and a connection structure thereof.

Background

The specimen clamp is a necessary experimental clamping plate tool for manufacturing garden plant wax leaf specimens, and the middle plant sample is clamped by binding the clamping plate by using a binding rope, so that the plant sample keeps the optimal shape and color to show the specimen state, the observation and research of regional and seasonal plants are realized, and the specimen clamp becomes one of the most powerful teaching means at present.

Traditional landscape plant specimen holder is with low costs, constitute the net piece with horizontal vertical arrangement of a plurality of stuff, single plant specimen uses two net pieces, the head that can tie the rope will be left on the side of net piece, put absorbent grass paper between two net pieces, place the plant specimen of laying flat between grass paper, tie up with the rope and can hand-carry, but the rope is binded in artificial compression, the operation is complicated, the method is difficult for mastering, strength according to everyone is different, make the compression of specimen holder bind the dynamics different, if the insufficient or strength of specimen preparation personnel experience, bind untightly or bind the mistake, can cause the dropout loose, can damage the difficult plant sample even.

Chinese patent No. 201711230863.8 discloses a plant specimen clamp, a specimen cabinet for fixing specimen clamp and fixing method thereof, and specimen clamp includes splint, splint include left splint and right splint, are equipped with left fixed plate in the left splint, are equipped with right fixed plate in the right splint, are equipped with clamping piece and lower clamping piece between left splint and the right splint, all are equipped with the V-arrangement backup pad in going up clamping piece and the lower clamping piece, one side of going up clamping piece and/or lower clamping piece is equipped with moisture sensor, controller and moisture sensor, alarm are connected, and the data transfer that moisture sensor detected is for the controller, controller control alarm work. The water absorption paper can remind relevant workers to replace the water absorption paper, and the V-shaped supporting plates and the air vents are arranged in the upper clamping piece and the lower clamping piece, so that the air flow is enhanced, and the specimen drying process is accelerated; the specimen cabinet can fix two sides and two ends of a plurality of specimen clamps at the same time, so that the conditions of toppling and the like are prevented; the specimen cabinet is equipped with air circulation device, and air circulation device dehumidifies the internal air of cabinet fast, and the air flow is with higher speed, prevents that the sample from going mildy. But left splint pass through the fixed band with right splint and are connected, the fixed band is the elastic cord, the fixed band that stimulates both sides respectively during the connection just can press from both sides tight plant specimen, the operation is complicated, and plant specimen places between the splint, plant specimen produces displacement left when pulling left, plant specimen produces displacement right when pulling right, the original structure of plant specimen has been damaged, the shape, be unfavorable for the preservation, plant specimen need change the paper that absorbs water many times in drying process in addition, take-up fixed band all can damage plant specimen at every turn, therefore there is the damaged structure that just does not accord with reality in the dry plant specimen who obtains.

Chinese patent No. 201520946064.0 discloses a latch type plant specimen clamp, which comprises two clamp plates, wherein a plurality of transverse clamp plates are fixed by a vertical beam, at least one end of the vertical beam at the side of the two clamp plates is provided with a binding rope through hole, and a bolt rope buckle is arranged at the end of the binding rope in a penetrating manner; the technical scheme has the technical advantages of simple and convenient operation, easy grasp, strong and comprehensive clamping force and higher specimen preparation quality. However, the specimen clamp also uses binding ropes to fix the clamping plates, the operation is complicated, the thicknesses of the leaves and the branches of the plant specimen are different, the clamping plates are not flat after being bound, the problem of local compression exists, if uniform compression is needed and the clamping is stable, more absorbent paper needs to be added, and the waste of the absorbent paper is caused.

Disclosure of Invention
