A manual cutting tool for lead wires on circuit board

Abstract

The invention discloses a manual cutting jig for a leading wire on a circuit board. The manual cutting jig comprises a [-shaped supporting seat, horizontal first groove rails are formed on the inner walls on two sides of the supporting seat, second groove rails are formed on the inner walls, on the lower sides of the first groove rails, of the supporting seat, threaded sleeves are fixed to the upper end surfaces at two ends of the first groove rails, and inserting holes communicating with the threaded sleeves are formed in the first groove rails; fastening bolts are connected into the screwingsleeves in a threaded mode, a waste frame is arranged in the supporting seat in an inserted mode, blocking edges are formed on the two side walls of the waste frame, and the blocking edges are connected into the second groove rails in an inserted mode; and a first guiding groove is formed in the rear end surface of the supporting seat, inverted L-shaped lower cutting blades are connected into thesupporting seat in an inserted mode, the lower cutting blades are composed of vertical parts and horizontal parts, guiding rods are connected to the vertical parts at the two ends of the lower cutting blades in an inserted mode, the two ends of the guiding rods are connected and fixed to the two side walls of the supporting seat in an inserted mode, and a plurality of lower cutting teeth are formed on the horizontal parts of the lower cutting blades. According to the manual cutting jig for the leading wire on the circuit board, the manual cutting jig can replace scissors to perform manual cutting, and cutting can be accelerated, so that the shearing efficiency is effectively improved, and meanwhile, the labor intensity of shearing workers is reduced.

Description

Technical field: [0001] The invention relates to the technical field of soldering jigs for electronic components, and more specifically relates to a jig for manually cutting lead wires on a circuit board. Background technique: [0002] At present, in the process of making prototypes, the assembly of electronic components and circuit boards is generally done manually. The operation process is to insert the sockets on the electronic components into the corresponding sockets on the circuit board, and then solder and fix them; After soldering, it is necessary to manually cut the pins or leads protruding from the back of the circuit board. At present, the manual structure uses simple scissors to cut one by one. However, a circuit board has many pins or leads. It is more convenient to use scissors to cut one by one. Trouble, low productivity. Invention content: [0003] The object of the present invention is to address the deficiencies in the prior art, and provides a manual cu...
