Description

C-shaped flower and fruit thinning scissors

Technical Field

The utility model relates to a scissors technical field especially relates to C type flower thinning fruit scissors.

Background

Thinning flowers, vegetables and fruits is an indispensable important link in fruit tree cultivation management, and is a necessary path for producing high-quality fruits and improving planting benefits. The method for thinning the flowers and the vegetables and the fruits comprises three ways of manual scissor thinning, mechanical thinning and chemical agent thinning, the chemical agent thinning is still in the research starting stage, the limitation of factors such as the area, variety, growth uniformity, flowering phase consistency and weather conditions is caused, the large-area popularization and application in production is difficult, researchers are also exploring the method for small-size electric mechanical thinning, but the links such as accuracy and damage are not mature, the continuous improvement is needed, and the popularization is difficult in a short time.

At present, flower thinning and vegetable thinning of fruit trees mainly depend on manual small scissors for thinning, the existing scissors can only cut off one flower or one small fruit at a time, one flower cluster of most fruit trees consists of five to six single flowers, the best-developed central flower and fruit only need to be reserved when the flower thinning and vegetable thinning are carried out, the rest four or five flowers are thinned, and therefore the flower thinning can be completed only by cutting off the cluster of flowers for four times and five times. The manual thinning is accurate, has no damage and no limiting factors, but has low efficiency and slow progress, needs to consume a large amount of labor and time, improves the production cost of fruits, and because the thinning is not in time, a tree body can consume a large amount of nutrients and moisture, and the growth and development of fruit trees are influenced.

Disclosure of Invention

To the problem that exists, the utility model aims at providing a C type is thinned flower and is dredged fruit and cut, its left shear blade and right shear blade including having C type structure, when the operation to during its closed angle structure inserts the flower cluster of compriseing a plurality of flower stalks, bring into a limit flower (fruit) back, it is rotatory for the arc center along central flower stalk, bring into other limit flowers (fruit) in proper order, final disposable whole cutting has not only improved work efficiency, also eliminates the damage to central fruit stalk simultaneously, improves the achievement rate.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the following describes the technical solution of the present invention with reference to the accompanying drawings and embodiments.

Referring to fig. 1-5, a C-shaped flower and fruit thinning scissors includes a scissors body 1, the scissors body 1 includes a left scissors body 11 and a right scissors body 12 hinged to each other, the left scissors body 11 and the right scissors body 12 sequentially include a left handle 111, a left scissors blade 112, a right handle 121 and a right scissors blade 122, preferably, a cutting edge is formed on one side of the left scissors blade 112 and the right scissors blade 122 close to each other, the left handle 111 and the right handle 121 are hinged to form the whole scissors body 1 through rivets, the left scissors blade 112 and the right scissors blade 122 are both of a C-shaped structure in the same direction, a cutting opening 101 is formed in the middle of the left scissors blade 112 and the right scissors blade 122, when in use, the left scissors blade 112 and the right scissors blade 122 of the C-shaped structure rotate around a central fruit stem, flower and fruit stems to be removed around the central fruit stem are sequentially thinned, the flower and fruit thinning operation is conveniently and quickly completed, and the problem that the straight scissors cannot remove the flower and fruit stems on the inner side is solved, meanwhile, the C-shaped flower and fruit thinning scissors also solve the problem of damage to the central fruit stalks and can ensure the yield of fruit trees. The limiting device for limiting the opening of the scissor opening 101 is arranged on the scissor body 1, so that the limitation on the maximum opening and the minimum opening of the scissor opening 101 is facilitated. The maximum opening is limited, so that the left handle 111 and the right handle 121 have ideal opening ranges, and the service time of the C-shaped flower and fruit thinning scissors is prolonged; limiting the minimum opening helps to limit the left and

right cutting edges

112, 122 from shearing too much and damaging the central stalk.

Specifically, stop device includes the equal horizontal and crisscross waist shape spacing hole 2 that sets up on left hand handle 111 and the right hand handle 121, two slide in the 2 overlapping portions in waist shape spacing hole and wear to be equipped with the locating part, it is preferred the locating part is torsional spring 3, and it includes torsional spring coil 31 and the torsional spring arm 32 of both sides, torsional spring coil 31 slides and wears to establish in the 2 overlapping portions in waist shape spacing hole, torsional spring arm 32 supports respectively on the inner wall of left hand handle 111 and right hand handle 121. When the scissor opening 101 is closed (as shown in fig. 4), the two waist-shaped limiting holes 2 on the left handle 111 and the right handle 121 simultaneously move towards the torsion spring coil 31 until the outer inner walls of the two waist-shaped limiting holes 2 contact the dead points on the two sides of the torsion spring coil 31, which is the minimum opening point when the scissor opening 101 is closed, and one flower and fruit thinning operation is also completed; when the scissor opening 101 is opened again (as shown in fig. 5), the torsion spring arm 32 is enabled to open the left handle 111 and the right handle 121 through the elasticity of the torsion spring 3, and on the contrary, the adjacent inner side walls of the two waist-shaped limiting holes 2 are tightly attached to the two sides of the torsion spring coil 31 to limit the opening position of the scissor opening 101, and meanwhile, the scissor opening 101 is opened to the set maximum range.

Further, in order to insert the scissors between the flower stalks and fruit stalks, the ends of the left and

right cutting edges

112 and 122 far away from the torsion spring 3 are both provided with a sharp-angled structure 102.

The principle of the utility model is that: stretch into between the flower stalk fruit stalk with left shear blade 112 and right shear blade 122 of this C type structure, use the center fruit stalk as the arc center, the operation is pruned to the outlying limit flower (fruit) stalk of center fruit stalk in the rotation, spacing hole 2 cooperation torsional spring 3 of two waists shape on left hand handle 111 and the right hand handle 121 simultaneously, can restrict the opening size of cut 101, it is more laborsaving during making the operation cut body, and can protect the center fruit stalk, rely on torsional spring 3's elasticity simultaneously, cut the completion back cut 101 and can open automatically once.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
