Description

Folding knife locking plate and folding knife Technical Field The utility model relates to a folding knife locking plate and a folding knife, and belongs to the technical field of knives. Background The reliability of the locking mechanism of folding knives as portable cutting tools directly determines the safety and durability of use. The frame lock is one of the main stream locking modes of the high-end folding knife because of the characteristics of simple structure, high strength and the like. The core component of the traditional frame lock, namely the locking plate, is usually made of titanium alloy or steel, and is meshed with the root groove of the blade through elastic deformation, so that the blade is prevented from being closed accidentally. However, in the conventional design, the locking piece of the frame lock and the handle mainly adopt two connection modes: 1. The split bolt is fixed, the locking plate is used as an independent component and is arranged on the inner side of the knife handle through bolts or rivets. According to the scheme, the locking plate mounting groove needs to be additionally machined, the locking plate is fastened by the bolts to maintain the tension of the locking plate, the locking plate is required to be independently manufactured and the mounting position is accurately matched, the machining steps and the tolerance control difficulty are increased, the thickness of the cutter handle is further increased, the cutter handle is not exquisite enough, additional parts are introduced when the bolts are fixed, the material and management cost is raised, the bolts are easy to loosen after long-term use, the locking plate is displaced or the tension is attenuated, and the risk of virtual locking is caused. 2. The semi-integral cutting forming is that the part of the high-end cutter designs the locking plate and the cutter handle into the same titanium alloy plate, the locking plate structure is processed through linear cutting or CNC, the locking plate elasticity is still required to be adjusted later or auxiliary fixing pieces are added, the number of parts is reduced in the semi-integral design, but the locking plate elasticity adjustment still depends on manual experience, standardization is difficult, the locking plate elasticity and the cutter handle rigidity are considered, the material selection is limited, after the locking plate is worn or damaged, a user needs to detach the cutter handle and recalibrate the locking plate position, and the operation is complex and depends on professional tools. Therefore, it is needed to provide a folding knife locking piece and a folding knife to solve the above technical problems. Disclosure of utility model The utility model is developed to solve the problems of structural redundancy, easy loosening caused by split bolt connection and complex maintenance of split bolt fixing and semi-integral cutting forming locking plate of the traditional frame lock, and simultaneously eliminate stress concentration of a joint surface, and remarkably improve locking stability and overall service life, and a brief overview of the utility model is given below to provide basic understanding about certain aspects of the utility model. It should be understood that this summary is not an exhaustive overview of the utility model. It is not intended to identify key or critical elements of the utility model or to delineate the scope of the utility model. The technical scheme of the utility model is as follows: The first scheme is that the folding knife locking plate comprises a locking plate and a knife handle connector, and the locking plate and the knife handle connector are integrally formed. Preferably, the locking plate is an elastic locking plate, and the locking plate is elastically clamped and engaged with the cutter head. The second scheme, a folding knife, including tool bit, handle of a knife and main shaft, still include scheme one folding knife locking plate, the handle of a knife connector fixed mounting of folding knife locking plate is on the handle of a knife, the tool bit is installed on the handle of a knife through the main shaft rotation, the locking plate elasticity clamping of folding knife locking plate is in the clamping groove of tool bit bottom. The folding knife is characterized in that the knife handle is internally provided with an avoidance groove, the locking plate is positioned in the avoidance groove when the folding knife is in a non-locking state, and meanwhile, the locking plate and the knife head are not clamped. Preferably, the bottom of the cutter head is provided with an arc-shaped limiting groove, the cutter handle is fixedly provided with a cutter stopping column, and one side of the cutter stopping column is arranged in the arc-shaped limiting groove. Preferably, the locking plate is provided with a limiting protrusion. Preferably, the number of the cutter handles is two, the two cutter handles are positioned
