Solder stick fly-cutting device
Technical field
The invention belongs to a kind of solder stick cutting tool, specifically, relate to a kind of solder stick fly-cutting device.
Background technology
In electronic technology training study course; Need carry out the circuit board welding training to the student, each of each student section training subject all need provide a certain amount of solder stick, and it is very few that solder stick provides; Can't satisfy teaching requirements; Solder stick provides too much, causes waste, also can bring bad operating habit to the student.
The shortcoming of prior art is: the cutting of solder stick can only be sheared according to experience by student or teacher, and cutting quantity is difficult to grasp.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of solder stick fly-cutting device, can accurately control the cutting quantity of solder stick, and can realize multistage solder stick time cutting.
Technical scheme of the present invention is following: a kind of solder stick fly-cutting device, and its key is: comprise the bar shaped seat, have the bar-shaped trough that the N road is parallel to each other on this bar shaped seat; Wherein the groove dike of one bar-shaped trough is marked with length scales; Said bar shaped seat is provided with slide rail, and this slide rail is parallel with said bar-shaped trough, is set with slide block on the slide rail; Said slide block has N vertically through hole; Be set with one in each vertical through hole and cut the tin cutter, the said cutter head of cutting the tin cutter passes said vertical through hole, and each cutter head of cutting the tin cutter stretches into respectively together in the said bar-shaped trough.
With the solder stick bar-shaped trough of packing into, just can cut quantitative solder stick as required by length scales, realize accurately quantitatively using of solder stick.
The quantity of N can be arranged as required: 3 roads, 5 roads, 6 roads, more bar-shaped trough is set can.Multi-segment structure has improved operating efficiency.
Can also all or part be cut tin cutter handle of a knife be connected on the same control lever according to the cutting needs.
Also be set with spring on the said blade of cutting the tin cutter, this spring lower end is placed on the said slide block, and the upper end contacts with the said handle of a knife of cutting the tin cutter.
Said bar shaped seat is arranged with two one slide rails in parallel, on the said slide rail of two ends suit of said slide block.
Also be set with main shaft on the said slide rail, kink has roller on the main shaft, is fixed with the protruding circle in N road on the said roller, and each protruding circle falls into said bar-shaped trough together.
The two ends of said main shaft and slide block all have downward opening chute, and this chute is sleeved on the said slide rail.
Main shaft and slide block slide on slide rail, simultaneously, can main shaft and slide block be taken off, and are convenient to put solder stick.
Beneficial effect: the present invention can accurately control the cutting quantity of solder stick, realizes fly-cutting, avoids waste, and lets the student form good scolding tin operating habit.

Fig. 2 is an assembly structure sketch map of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described.
Like Fig. 1, shown in 2: a kind of solder stick fly-cutting device, comprise bar shaped seat 1, have the bar-shaped trough that the N road is parallel to each other on this bar shaped seat 1; Wherein the groove dike of one bar-shaped trough is marked with length scales; Said bar shaped seat 1 is provided with slide rail 2, and this slide rail 2 is parallel with said bar-shaped trough, is set with slide block 3 on the slide rail 2; Said slide block 3 has N vertically through hole; Be set with one in each vertical through hole and cut tin cutter 4, the said cutter head of cutting tin cutter 4 passes said vertical through hole, and each cutter head of cutting tin cutter 4 stretches into respectively together in the said bar-shaped trough.
Also be set with spring 5 on the said blade of cutting tin cutter 4, these spring 5 lower ends are placed on the said slide block 3, and the upper end contacts with the said handle of a knife of cutting tin cutter 4.
Said bar shaped seat 1 is arranged with two one slide rails 2 in parallel, on the said slide rail 2 of the two ends suit of said slide block 3.
Also be set with main shaft 6 on the said slide rail 2, kink has roller 7 on the main shaft 6, is fixed with N road protruding circle 7a on the said roller 7, and each protruding circle 7a falls into said bar-shaped trough together.
Can wait protruding circle 7a solder stick extruding smooth after cutting again.
The two ends of said main shaft 6 and slide block 3 all have downward opening chute, and this chute is sleeved on the said slide rail 2.
