Embodiment
It refer to shown in Fig. 1 to Fig. 4, that show the concrete structure of the preferred embodiments of the invention, include body
10th, preceding blade 20 and rear blade 30.
The body 10 includes substrate 11, preceding mounting bracket 12 and rear mounting bracket 13；The preceding mounting bracket 12 and rear mounting bracket 13
The bottom of substrate 11 is both secured to, preceding mounting bracket 12 and rear mounting bracket 13 left and right extension, rear mounting bracket 13 are located at preceding mounting bracket
12 rear side；In the present embodiment, the surface of the substrate 11 is provided with multiple mounting holes 101, part mounting hole 101 and screwed togather
Peg 14 is connected with, to be adapted to the stencil printer of all size, versatility is more preferable.
The preceding blade 20 and rear blade 30 tilt the bottom for being installed on preceding mounting bracket 12 and rear mounting bracket 13, preceding blade respectively
20 and rear blade 30 left and right extension and time interval set, the edge of a knife of preceding blade 20 and the edge of a knife of rear blade 30 are towards front lower
Side；In the present embodiment, neck 102 is provided with the preceding mounting bracket 12, the preceding blade 20 is installed in neck 102, and preceding
Magnet 15 is provided with mounting bracket 13, magnet 15 adsorbs preceding blade 20, with blade 20 before being convenient for changing.And, the rear knife
Piece 30 is fixed on by fixed strip 16 on the rear side inclined-plane of rear mounting bracket 13.
And, the left and right ends of the body 10 are provided with gear block tin 40.In the present embodiment, it is described gear block tin 40 can on
Under automatically adjust the end for being movably arranged as body 10.Slide rail 17 is provided with the body 10, the slide rail 17 tilts extension,
