Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to blades such as pruning shears, pruning shears, and saws having a disinfectant supply means.

(Prior Art) Generally, in the cultivation of plants such as trees or flower petals, due to the fact that many individuals are grown and cultivated together, great care is taken to prevent the occurrence of diseases and the transmission of pathogenic bacteria. This is because once a disease or the like occurs and is transmitted to other healthy individuals, it will have a significant negative impact on the quality of the grown plants and their yield. In other words, when harvesting or pruning, great care must be taken to avoid transmitting the disease, and if the knife used to cut a diseased plant is used to cut another plant, pathogenic bacteria may adhere to the blade tip. Because of this, pathogenic bacteria can enter through the cut end through the cutter, and in some cases, pathogenic bacteria that have entered the branch through the cut end can also enter the plant and cause it to wither. For this reason, conventionally, when using a cutlery, the cutting edge of the cutter is immersed in a plant disinfectant to sterilize it, or the plant disinfectant is supplied directly to the cut end of the plant via a valve. .

(Problem to be solved by the invention) However, with the former method, the disinfecting effect cannot be maintained for multiple operations with one immersion, so disinfecting the cutting edge before starting the operation is sufficient. Instead, it is troublesome from the viewpoint of work efficiency to immerse the cutting edge in a disinfectant solution at appropriate intervals or every time to ensure the best disinfection effect.

The latter solves the above-mentioned problems, but does not handle highly concentrated disinfectants, is difficult to be compact, requires precision in manufacturing the valve, which increases costs, and prevents the inside of the valve from solidifying. Since it is easy to use, there were problems such as cleaning was troublesome.

An object of the present invention is to provide a cutter having a disinfectant supply means that solves this problem.

(Means for solving the problem) A cutlery having a disinfectant supply means according to the present invention includes:
In a cutlery having a disinfectant supply means for appropriately supplying a plant disinfectant from a supply tank via a flexible tube, the disinfectant supply means includes a holding member integrally fixed to a grip of the cutter, and the holding member. a pressing member rotatably supported by the member; a pressing member that presses the flexible tube with the pressing member and urges the flexible tube to constantly prevent passage of the plant disinfectant;
It is characterized by comprising an operating member provided at one end of the pressing member, which releases the pressing of the flexible tube by the pressing member against the elasticity of the elastic member to allow passage of the plant disinfectant. That is.

Note that the term cutlery here refers to a broad concept that includes various types of scissors such as pruning shears, pruning shears, and saws, as well as knives and saws.

(Function) According to the present invention, since the disinfectant supply means is attached to the cutter itself, the cutter can be held in one hand to cut off the plant and also to supply the disinfectant directly to the cut end of the plant. sell. In addition, by pressing the operating member 32 against the elasticity of the elastic member 26, in other words, the pressing member 26
By releasing the pressure on the flexible tube 19 by 4, the plant disinfectant is sequentially released into the flexible tube 1.
9 to the disinfectant solution outlet member 20, and an appropriate amount of disinfectant solution is supplied from the disinfectant solution outlet member 20 to the cut end of the plant. When the supply of the desired disinfectant solution is finished, by releasing the operating member 32, the flexible tube 19 is returned to its original state of being pressed by the pressing member 24, and the supply of the disinfectant solution is stopped.

(Effects of the Invention) As is clear from the above description, the cutter having the disinfectant supply means according to the present invention allows cutting off plants and supplying the disinfectant with one hand.
There is no need to change hands each time you perform both tasks. This is therefore advantageous, especially when one hand is needed for personal safety, such as when climbing and pruning a tree. And since the disinfectant supply means is at hand, there is no need to be nervous about checking it.

In addition, the appropriate amount of disinfectant can be constantly supplied with a simple operation using the operating member, eliminating the need to immerse the blade tip in disinfectant each time, which is required in the past.
It is possible to ensure the perfect disinfection effect.

Furthermore, since the disinfectant supply means can have an extremely simple configuration of just pressing the flexible tube with a pressing member, smooth supply can be ensured even when using highly concentrated disinfectants, and a high degree of It has various advantages such as low manufacturing cost since it does not require precision, and easy cleaning and maintenance.
