Operation principle of the present invention:
The motor shaft output of drive motors 6 is fixedly connected with cam 4; Drive motors 6 directly driving cam 4 rotates around output shaft; Because driving member 7 is arranged in the cam path 41 of cam 4, move so the rotation of cam 4 can drive driving member 7, and then drive push rod 3 is done the cam curve motion; Because guide pillar 43 is limited in the push rod gathering sill 31 and slides, spacing guide pillar 81 is limited in the gathering sill 51 on the guide plate 5 and slides, can only be along gathering sill 51 moving linearlies of guide plate 5 thereby define push rod 3.Therefore, above-mentioned transmission mechanism can be converted into the round rectilinear motion of push rod 3 along gathering sill 51 directions of guide plate 5 with drive motors 6 rotatablely moving of generation.
Because spacing guide pillar 81 forms matched in clearance and is limited to slip in the said sliding tray 21 with the sliding tray 21 of cutting blade 2; When push rod 3 promotes to slide in the gathering sill 51 of spacing guide pillar 81 at guide plate 5; Can know by motion vector is synthetic; Spacing guide pillar 81 will slide in the sliding tray 21 of cutting blade 2, and order about cutting blade 2 and rotate around the axis of the guide pillar 43 that flexibly connects with cutting blade 2 other ends, and cutting blade 2 partly gets in the loophole 10; Thereby realized the oblique cutting of light beam, as shown in Figure 8; When a pair of drive motors 6 drove pair of push rods 3 simultaneously with the identical direction of identical speed, as shown in Figure 9, cutting blade 2 can move into or shift out loophole 10 abreast, thereby can realize the parallel cutting of light beam.
Because said cutting blade 2 assemblies are usually by paired use; And relatively be arranged on the both sides of loophole 10; So cutting blade 2 need move into the half the of loophole 10 at least when being in maximum cut state, just possibly use a pair of cutting blade 2 to realize the cutting fully (being black out) of light beams.
