The technical scheme is that the device comprises two movable rods hinged with each other to form a scissor-shaped structure, wherein the middle parts of the two movable rods are hinged with each other to form a scissor-shaped structure, an inward arc-shaped clamping plate is fixed at the upper end of each movable rod, the two clamping plates are coaxial, an arc-shaped plate is arranged in each clamping plate, and the openings of the two arc-shaped plates are opposite to each other and form a complete cylinder; the outer circular surface of the arc-shaped plate is provided with a groove, the inner side wall of the clamping plate is fixedly provided with a sliding block corresponding to the groove, and the sliding block is arranged in the groove, so that the arc-shaped plate can rotate in the clamping plate; the rear end of the clamping plate is provided with a semicircular blade, the cutting edges of the two blades are arranged inwards, and the blade is positioned at the rear side of the arc-shaped plate.

Further, the groove is a T-shaped groove, the sliding block is a T-shaped block, the sliding block is positioned in the middle of the T-shaped groove in a natural state, the sliding block is positioned in the middle of the groove, and tension springs are connected to the two ends of the sliding block and the groove.

Further, torsion springs are installed at the hinge parts of the two movable rods.

Further, the front end of the arc plate extends out of the clamping plate.

Further, the lower end of the movable rod is sleeved with a rubber sleeve.

The utility model has ingenious structure, can realize one-hand operation on the premise of ensuring that the old leaves are broken off rapidly, and the tool clamps the root parts of the leaves and stems after cutting, so that the old leaves can be conveniently placed on the cauliflower without two-hand operation, can be realized by one hand, reduces the bending amplitude, is convenient and quick, and is suitable for sunshade steps in the planting of the cauliflower.

Detailed Description

The following describes the embodiments of the present utility model in further detail with reference to the accompanying drawings.

As shown in fig. 1 to 3, the utility model comprises two movable rods 1 hinged with each other in a scissor shape, wherein an arc-shaped clamping plate 2 with an inward opening is fixed at the upper end of each movable rod 1, the two clamping plates 2 are coaxial, an arc-shaped plate 3 is arranged in each clamping plate 2, and the openings of the two arc-shaped plates 3 are opposite to each other and form a complete cylinder; the outer circular surface of the arc-shaped plate 3 is provided with a groove 4, the inner side wall of the clamping plate 2 is fixedly provided with a sliding block 5 corresponding to the groove 4, and the sliding block 5 is arranged in the groove 4, so that the arc-shaped plate 3 can rotate in the clamping plate 2; the rear end of the clamping plate 2 is provided with semicircular blades 6, the cutting edges of the two blades 6 are arranged inwards, and the blades 6 are positioned at the rear side of the arc plate 3.

In order to prevent the clamping plate 2 from being separated from the arc-shaped plate 3, the groove 4 is a T-shaped groove, the sliding block 5 is a T-shaped block, the sliding block 5 is positioned in the middle of the T-shaped groove in a natural state, the sliding block 5 is positioned in the middle of the groove 4, and tension springs are connected to the two ends of the sliding block 5 and the groove 4.

In order to facilitate one-hand operation, torsion springs are arranged at the hinge positions of the two movable rods 1.

In order to realize that the clamping plate 2 can clamp the leaves and stems of old leaves, the front end of the arc-shaped plate 3 extends out of the clamping plate 2.

In order to improve the comfort level of hands, the lower end of the movable rod 1 is sleeved with a rubber sleeve 7.

It is worth noting that the scheme is characterized in that the scheme is used for clamping and then cutting, and finally the cut old leaves are lifted and placed above the cauliflower in a proper position, so that the purpose of sunshade is achieved, one-hand operation is achieved, the process is finished at one time, the labor intensity in cutting the old leaves can be greatly improved, and the sunshade efficiency of the cauliflower is improved.

When the sunshade device is used, in a natural state, due to the action of the torsion spring, the two movable rods 1 are separated from each other, the two arc plates 3 at the upper ends of the movable rods 1 are not contacted, at the moment, the lower ends of the movable rods 1 are pinched by hands, the root parts of the leaves and stems of the old leaves are arranged between the two arc plates 3, at the moment, the movable rods 1 are pinched, the two movable rods 1 are close to the middle, after the two arc plates 3 are contacted with each other to form a complete cylinder, the leaf and stem parts of the old leaves are clamped, in the process, the two semicircular blades 6 in the rear end cavity of the clamping plate 2 cut into the old She Shejing, but are not completely cut, at the moment, the two movable rods 1 are pinched and rotate around the cylinder formed by the two arc plates 3, during rotation, the two blades 6 rotate around She Jingzhou of the old leaves and stems are completely cut, at the moment, the two movable rods 1 are kept in a tight state, the leaves and stems of the old leaves are still clamped by the two arc plates 3, the whole old leaves are lifted and are arranged above the flower, so that sunshade is realized.

In the process, before the leaves and stems of the old leaves are not completely broken, the two arc plates 3 tightly clamp the leaves and stems of the old leaves, and in the process that the two movable rods 1 rotate around the cylinder formed by the two arc plates 3, the arc plates 3 clamp the leaves and stems and do not rotate, so that tension springs in the grooves 4 are in a stressed state, when the leaves and stems are completely broken, under the action of a plurality of tension springs, the old leaves can instantaneously rotate for an angle until the sliding blocks 5 are restored to the middle initial position of the grooves 4, and by virtue of the characteristics, the judgment of whether the leaves and stems of the old leaves are completely broken or not is greatly facilitated by an operator.
