Shown in Fig. 2,3 and 4, the blocking device of the utility model eye-protection cover of cutting machine mainly is mounted in the side of saw arm 100, this saw arm 100 is provided with a convex surface part 101, saw arm 100 is pivoted with on the another side and can lifts an eye-protection cover 102 that opens up and down, and the utility model comprises a positioning seat 20, an axostylus axostyle 30, retaining follow block 40, a poke rod 50 and a flexible member 60.

This positioning seat 20 is installed in cutting machine saw arm 100 side edge, the positioning seat 20 inner recessed empty holding parts 21 that form, these holding part 21 bottom center places run through be provided with one the perforation 22, it is solid on convex surface part 101 with positioning seat 20 spiral shells that one screw 23 penetrates this perforation 22, the outstanding flange 24 that forms of these positioning seat 20 lateral margins, this flange 24 can abut against the side of convex surface part 101, positioning seat 20 is abutted against is positioned on the convex surface part 101, and before the positioning seat 20 the Hou both sides be provided be connected with holding part 21 one run through mesopore 25.

This axostylus axostyle 30 passes positioning seat 20 mesopores 25, its front end place is provided with to what end positioning seat 20 lateral margins and one supports stop ring rank 31, and Hou end place is provided with a thread segment 32, on thread segment 32 lateral circle surfaces and be provided with a plane of orientation 33, be screwed into a nut 34 on this thread segment 32, this axostylus axostyle 30 is passed and this positioning seat 20 of horizontal what on.

This retaining follow block 40 is fixed in axostylus axostyle 30 front end places and L-shaped in the riveted joint mode, is arranged with a block 41 in its end, and these retaining follow block 40 outer rims are concaved with a recessed edge 42.

One poke rod, 50 pivots are consolidated at axostylus axostyle 30 Hou end places and are taken the shape of the letter U, form an angle of inclination with this retaining follow block 40, run through in its end and to be provided with a locating hole 51, in half is that vertical plane and half are periphery week, the axostylus axostyle 30 of plane of orientation 33 places fixedly in this locating hole 51 of what, therefore poke rod 50 can be together and these axostylus axostyle 30 turns, and be arranged with a pressure handle 52 of pushing turn poke rod 50 for hand in its end.

This flexible member 60 cover pivots support on the stop ring rank 31 and are torsionsprings axostylus axostyle 30, the recessed edge 42 of one end contact retaining follow block 40, and the other end is the arm body of contact saw arm 100 then, makes retaining follow block 40 have restoring force to saw arm 100 directions.

Please cooperate consult shown in Figure 5, under obsolete state, this retaining follow block 40 is subjected to the contact of flexible member 60, and maintain the position that presses saw arm 100 always, if the user presses down this saw arm 100 when desiring to carry out work, the eye-protection cover 102 on the saw arm 100 will upwards lift and open, at this moment, the lid edge of eye-protection cover 102 promptly can be subjected to keeping off supporting of follow block 40 to be ended, and eye-protection cover 102 can't continue to lift and opens and form blocking.

Please cooperate consult shown in Figure 6, when the user desires to carry out sawing work, at first push the pressure handle 52 of this poke rod 50 with hand, poke rod 50 will drive the 40 outside switchings of retaining follow block integratedly, this time, retaining follow block 40 block eye-protection cover 102 no longer, eye-protection cover 102 can free lift on saw arm 100 and open mobilely, and this has just removed the blocking of eye-protection cover 102.In addition, the lateral edges of eye-protection cover 102 corresponding positioning seats 20 can make eye-protection cover 102 lift when opening, and positioning seat 20 was kept away and normal upset in eye-protection cover 102 edges.Have an angle of inclination by what

poke rod

50 and 40 of follow blocks of retaining, therefore poke rod 50 is kept certain distance with saw arm 100 arm bodies under normal conditions, and the user can make things convenient for and rapidly by supporting this pressure handle 52, carry out the action of unlocking.

So, the blocking device of the utility model eye-protection cover of cutting machine is by at saw arm 100 arranged outside positioning seats 20, this positioning seat 20 one earth's axis pivots one retaining follow block 40 and poke rod 50, making this retaining follow block 40 can prevent that eye-protection cover 102 from lifting opens to form locking, but and push 40 switchings of poke rod 50 one interlocks retainings follow block, make eye-protection cover 102 no longer be subjected to block and can normally lift and open.The utility model is formed with the quite easy member of shape, and is all quite easy and rapid in manufacturing and assembly, and the utility model can reach the effect of locking in the use really, more can meet user's operating habit, has operability very easily.
