Description
Technical Field
The utility model belongs to the technical field of the fruit pruning shear, concretely relates to novel fixed tool bit of fruit pruning shear.
Background
In the prior art, fruit shears are various in types, and are popular among people because the fruit shears can conveniently, quickly and labor-saving shear plant branches. The existing fruit pruning shears are all provided with a shearing mechanism consisting of a fixed cutter head and a movable cutter head, the movable cutter head is driven by a motor to shear by taking the fixed cutter head as a reference, the movable cutter head is easy to loosen and move after long-time shearing operation, the movable cutter head needs to be replaced, the fixed cutter head also needs to be replaced, and therefore the service life of the fruit pruning shears with the traditional structure is influenced due to the insecure connection of the fixed cutter head.
In addition, especially when the electric long fruit pruning shears are operated, the movable cutter head and the fixed cutter head are easily deflected when the movable cutter head and the fixed cutter head perform opposite shearing movement under the influence of long operating distance and irregular branch shapes, namely the movable cutter head and the fixed cutter head are not stressed by opposite straight lines, but are deflected and deflected under the influence of the branches, so that the direction of the cutting force is deflected and even damaged. Therefore, the cutter is difficult to cut, the cutter head can be obliquely supported and pried, the fixed cutter head is easy to shift and loosen, and finally the cutter head cannot be used. In addition, the fixed cutter head is only fastened through a bolt, so that the defect of the traditional fruit pruning shear for fixing the cutter head is obvious.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the technical problem that the fixed cutter head of the traditional fruit pruning shears is easy to shift, damage and connect insecurely, and providing a novel fixed cutter head of the fruit pruning shears.
In order to achieve the above purpose, the utility model discloses a technical scheme is:
a novel fruit branch shear fixed cutter head comprises a fixed cutter head seat and a fixed cutter;
the rear end of the fixed tool bit seat is provided with a mounting hole;
the front end part of the fixed cutter head seat is provided with a supporting part for bearing the fixed cutter; the supporting part is provided with a sleeve; the rear part of the fixed cutter is provided with a positioning hole which is correspondingly inserted at the outer diameter of the sleeve;
a fastening hole I is formed in the rear part of the supporting part and corresponds to a fastening hole II formed in the rear end of the fixed cutter;
the front end of the fixed cutter head seat is provided with a protruding limiting part arranged along the edge of the rear part of the supporting part, and the protruding limiting part is connected with the rear end of the fixed cutter in a matched mode.
The utility model has the advantages that:
decide the cutter and can improve the firmness of connection and the stability of support under the effect of the spacing portion of protrusion, be difficult to damage under the effect of external force not hard up, compare with traditional unilateral bolt-up's connected mode, improve obviously. The 7075 alloy aluminum material has high hardness and is not easy to break. The fixed part of the blade is sleeved with a stainless steel pipe wear-resistant fixed cutter blade and fixed by screws. Not easy to loose and simple to assemble.
