Abstract
The utility model discloses a loosening prevention mechanism for a fruit pruning shear head, which comprises a fixed outer ring and a gear; the fixed outer ring is provided with a mounting hole and a fixing hole; a gear groove is arranged at the inner diameter of the fixing hole; gears which are matched and inserted with the gear grooves are arranged in the fixing holes; the circle center of the gear is provided with an inserting hole, and the inserting hole and the fixing hole correspond to each other in the same circle center. The tool bit can improve the firmness of connection and the stability of support under the matching meshing effect of gear groove and gear, and the improvement that is difficult to damage is not hard up obvious under the effect of external force. The mounting hole, the fixing hole and the inserting hole are in mirror image correspondence by taking the central line of the fixed outer ring as a symmetry axis, and the stability of the direction of the force is ensured.
Description
Technical Field
The utility model belongs to the technical field of the fruit branch is cut, concretely relates to locking mechanism that moves for fruit branch scissors head.
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 cutter head of the traditional fruit branch shears is easy to shift, damage and loose connection, and providing a loosening prevention mechanism for the cutter head of the fruit branch shears.
In order to achieve the above purpose, the utility model discloses a technical scheme is:
a loosening prevention mechanism for a fruit pruning shear head comprises a fixed outer ring and a gear;
the fixed outer ring is provided with a mounting hole and a fixing hole;
a gear groove is formed in the inner diameter of the fixing hole; a gear which is matched and inserted with the gear groove is arranged in the fixing hole; the circle center of the gear is provided with an inserting hole, and the inserting hole corresponds to the fixing hole in the same circle center.
Furthermore, one side surface of the gear is provided with a raised protruding platform which concentrically corresponds to the inserting hole; the protruding platform is of a hexagonal structure.
Further, the fixed outer ring is of a water drop-shaped structure; the mounting hole, the fixing hole and the inserting hole are in mirror image correspondence with the central line of the fixed outer ring as a symmetry axis.
The utility model has the advantages that:
the tool bit can improve the firmness of connection and the stability of support under the matching meshing effect of gear groove and gear, and the improvement that is difficult to damage is not hard up obvious under the effect of external force. The mounting hole, the fixing hole and the inserting hole are in mirror image correspondence by taking the central line of the fixed outer ring as a symmetry axis, and the stability of the direction of the force is ensured.
