Detailed Description

The following describes the embodiments of the present utility model further with reference to the drawings. The description of these embodiments is provided to assist understanding of the present utility model, but is not intended to limit the present utility model. In addition, the technical features of the embodiments of the present utility model described below may be combined with each other as long as they do not collide with each other.

Examples

The hand-free flower and branch pruning tool comprises two groups of articulated scissor bodies, wherein each group of scissor bodies comprises a cutter body 1; the clamping assemblies 4 are arranged on the same side of the two cutter bodies 1; the clamping assembly 4 comprises a support plate 401 fixedly mounted on the cutter body 1, and the opposite sides of the two support plates 401 are connected with a clamping plate 402 through springs 403.

The hand-free flower and branch pruning tool has the advantages that when the hand-free flower and branch pruning tool is used for pruning, only one hand is needed to operate the pruning tool, flowers and branches to be pruned do not need to be held, labor intensity is reduced, the cut flowers and branches can be clamped by the aid of the two clamping plates 402, and the flowers or the arms can be prevented from being scratched due to the fact that the flowers and the branches fall down.

Specifically, the clamping assembly 4 further includes a clamping portion 404 having an opening at one end; the clamping part 404 is made of spring steel; the bottom of the support plate 401 is fixedly connected with the upper end of the clamping part 404. When the barbed flower branches need to be trimmed, the open end of the clamping part 404 is pulled to generate elastic deformation, then the clamping part 404 is inserted into the cutter body 1, and the clamping part 404 is clamped on the cutter body 1 by means of the elastic force of the deformation of the clamping part 404. When it is not necessary to clamp the flower branches to be cut, the clamp 404 can be removed to restore the conventional pruning tool.

Specifically, the part of the clamping part 404, which is in contact with the lower end of the cutter body 1, is provided with anti-skid patterns 4041; the anti-skid lines 4041 can be increased, so that friction force between the clamping part 404 and the lower end surface of the cutter body 1 can be increased, and the clamping part 404 is prevented from loosening in the pruning process; a handle 405 is installed at the lower end of the clamping part 404, and the handle 405 facilitates opening of the clamping part 404.

Specifically, the edges of the support plate 401 and the grip plate 402 are provided with excessive rounded corners, preventing sharp edges from scratching flowers and arms.

Specifically, the cutting edge 101 of the cutter body 1, the support plate 401 and the clamping plate 402 are arc-shaped. Compared with a linear cutting edge, the arc cutting edge is more labor-saving, and branches are not easy to crack during trimming.

Specifically, one end of the cutter body 1 is fixedly connected with a cutter rest 2; the other end of the tool rest 2 is fixedly connected with a threaded rod 3; the threaded rod 3 is externally connected with a threaded sleeve 5. The length of the threaded rod 3 extending into the threaded sleeve 5 can be adjusted by rotating the threaded sleeve 5, so that the effective length of the pruning tool is adjusted, and reasonable adjustment can be performed according to the distance between the pruning flower and branch and the human hand.

Specifically, for the convenience of holding, the outer wall of the screw sleeve 5 is fixedly connected with an arc-shaped handle 7.

Specifically, an elastic member 6 is fixedly connected between the two tool holders 2. The elastic member 6 provides a repulsive force after trimming on the one hand, helps to rapidly open the trimming tool, and on the other hand, limits the wide-angle opening of the trimming tool to injure a person accidentally.

Specifically, the elastic member 6 is a spring.

Specifically, the head of the cutter body 1 is provided with a transition fillet, so that the head of the cutter body 1 is prevented from accidentally injuring flowers and people.

The working principle of the utility model is as follows:

when the barbed flower branches need to be trimmed, the handle 405 is held, the clamping part 404 is pulled to generate elastic deformation, then the clamping part 404 is inserted into the cutter body 1, the handle 405 is released, and the clamping part 404 is clamped on the cutter body 1 by means of the elastic force of the deformation of the clamping part 404. During trimming, the cut flowers can be clamped by the two clamping plates 402. According to the utility model, only one hand is needed to operate the pruning tool, flowers to be pruned do not need to be held, the labor intensity is reduced, and the damage to flowers or the scratch of arms caused by the falling of the flowers can be avoided. When it is not necessary to clamp the flower branches to be cut, the clamp 404 can be removed to restore the conventional pruning tool.

The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings, but the present utility model is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the utility model, and yet fall within the scope of the utility model.
