Description

TECHNICAL FIELD

[0001] The utility model relates to fishing gear technical field, concretely relates to a self-locking type corner fort. BACKGROUND

[0002] The corner fort is used for fixing the frame pole, and the fishing rod is placed on the frame pole to support and fix the fishing rod, so that both hands can be freed, and the corner fort usually comprises a plurality of rotating structures to adapt to the force angle of different anglers through multi-angle adjustment, so that the problem of tennis elbow of the angler is avoided. The corner fort has a plurality of rotating structures, and several rotation stopping structures are provided to lock the rotation of the rotating structure. The existing corner fort usually adopts a screw to lock the rotation of the rotating structure. The commonly used corner fort on the market, such as the stainless steel corner fort disclosed in CN 220831530 U, sets an opening on the rotating arm, and the barrel is hingedly installed on the opening of the rotating arm, and then the rotation of the barrel is locked by a bolt. However, the stress point of the corner fort with such a structure is concentrated at the opening of the rotating arm, which is easy to cause deformation at this position, thereby affecting the service life of the corner fort. In addition, because the use environment of the corner fort is relatively complex, the bait on the angler's hand often adheres to the bolt, causing scale accumulation between the bolt and the rotating arm, so that the bolt cannot be locked in place. In addition, long-term use will cause wear between the bolt and the rotating arm and between the hinge and the rotating arm, which will also cause the bolt to be unable to lock in place. In addition, the corner fort with such a structure needs the angler to rotate the bolt with one hand and rotate the fishing rod with the other hand to adjust the angle, which is troublesome to use. Moreover, the bolt head is exposed on the side edge of the rotating arm, and the fishing line is easy to hook the bolt head, which also brings inconvenience to use. In addition, the existing corner fort with such a structure has a barrel rotatingly installed above the rotating arm. Because the barrel is an L-shaped structure, the rotation of the barrel will be interfered by the rotating arm, which will limit the rotation angle of the barrel. When the corner fort is folded, the barrel cannot be rotated below the rotating arm, thereby reducing the size of the corner fort.
