Description

Retractable Tongs {Retractable Clip}

The present invention relates to a retractable forceps, and more particularly, to a retractable forceps that can freely adjust the inner diameter of the forceps by including a retractable bar that can be expanded and contracted.

In general, in the case of vine plants such as cucumbers and pumpkins, the vines are wound around the feature in the process of growing the crops, so the attraction is required.

Attracting method can be divided into a method of encouraging the attracting rope around the plant stem and a method of fixing the plant stem using forceps. The method of fixing a manned string on the stem has a disadvantage in that it is cumbersome to remove the string when the stem is removed after the fruit is harvested. Using forceps to fix the fruit as it grows to the attracting string is very easy to attract and has the advantage of easy to remove the stem after fruit harvest. In particular, manned tongs are intended to grow young crops or young seedlings straightly.The crops grow straight by installing manned lines on one side of the cultivated crops and fixing pins on the manned lines so that the crops grow along the manned lines. To do that. However, the existing attracting tongs are produced in a constant size of the crop attracting grooves can interfere with the growth of the crop and damage the stem of the crop. In addition, there is a problem that the work load is increased due to the need to artificially change or replace the position of the tongs as the crop grows.

The present invention discloses a fixed tong tongs that can be used more effectively by structurally improving the disadvantages of the existing tongs to improve the fixing force and to freely adjust the inner diameter of the tongs.

Korean Patent No. 20-2012-0000050 relates to a crop stem attracting forceps, the crop stem attracting forceps is a fixed portion for fixing the forceps to the fixed shaft to a conventional crop attracting forceps, a pair of main body is assembled by a spring Characterized in that it is included, the fixing portion is provided in the tongs separately from the support for supporting the branches of the crop, characterized in that the fixing portion is provided with two or more different grooves. The fixing portion may be adjustable in length and rotatable, and may have a structure such as an unevenness for fixing, or an anti-slip means such as rubber or silicone. The support has a smaller radius than the usual attracting clips or tongs, and there is no detachment of the stem even if the support is slightly opened to the end of the sawtooth support. The operation part is enlarged, the finger touching part is concave, and the concave-convex shape is inserted for convenient use. The present invention has the above structure and is characterized in attracting agriculture, fruit lessons, especially vine branches.

Korean Laid-Open Patent Publication No. 20-2016-0002652 relates to vine crop tongs that can be commonly used in manned lines installed horizontally and vertically. More specifically, a cylindrical shape in which a jaw is formed and a stem is inserted into the inside It has a fixed groove of the rotating part is located in the center is formed between the fixing groove and the rotating part, and the outer side is composed of a tongs for coupling the spring to the spring to which the spring is bound, the fixing groove for fixing the stem when the tongs open The fixing part for fixing the manned line is opened at the same time and a pair of both ends of the rotating part on the upper and lower surfaces of the vine crop stem manned tongs coupled to the conventional vertical manned line which puts the manned line into the fixed part and puts the stem into the fixing groove. Each of the protrusions is formed to form a protrusion groove facing the inner side of the protrusion, and the upper portion of the protrusion groove is formed as an injection groove. When the claws located on both sides of the rotating part open the tongs so that the centers of the ridge grooves on both sides coincide with each other, and the claws are picked up so that the lateral grooves on both sides are shifted at a predetermined angle, and at the same time the horizontal guideline It can be combined or separated, and can be used regardless of the direction of crop and stem cultivated, thereby obtaining vine crop stem tongs with excellent versatility.
