Surprisingly with transferring to cause personal accidental injury;The present invention has many advantages, such as that structure is simple, easy to make, economic and practical.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
The present invention is further explained in the light of specific embodiments.
The safety catch of belt transmission grass trimmer work cutter shaft of the invention, including the rotation of clutch lever 1, clutch hand handle
Turn fulcrum 2, clutch flexible shaft 3, clutch flexible shaft support 4, tensioning wheel 5, clutch tension spring 6, clutch tensioning bracket 7, clutch tensioning bracket
Rotation fulcrum 8, drive pulley 9, negative pulley wheel 10, belt 11, belt brake frame 12, belt brake frame rotation fulcrum 13,
Belt brake frame tension spring 14, brake shoes 15 and clutch tension spring fixing seat 16;
The clutch lever 1 is hinged in grass trimmer rack by clutch hand handle rotation fulcrum 2, clutch flexible shaft 3 by two from
It closes flexible axle support 4 to be mounted in grass trimmer rack, the upper end of clutch flexible shaft 3 is connected with clutch lever 1, under clutch flexible shaft 3
End is connected with clutch tension spring 6, and clutch is tensioned bracket 7 and is hinged in grass trimmer rack by clutch tensioning bracket rotation fulcrum 8,
Tensioning wheel 5 is installed in the upper end of clutch tensioning bracket 7, the other end of the clutch tension spring 6 is connected to tensioning wheel 5 and clutch
It is tensioned on the clutch tensioning bracket 7 between bracket rotation fulcrum 8;Be rotatably equipped in grass trimmer rack drive pulley 9 with
Negative pulley wheel 10, is equipped with belt 11 on drive pulley 9 and negative pulley wheel 10, and the tensioning wheel 5 cooperates with belt 11;
Belt brake frame 12 is hinged in grass trimmer rack by belt brake frame rotation fulcrum 13, in belt brake frame rotation fulcrum 13
Brake shoes 15 is fixed on the belt brake frame 12 on right side, brake shoes 15 compresses the negative pulley wheel 10;Clutch tension spring is solid
Reservation 16 is fixed in grass trimmer rack, and belt brake frame tension spring 14, belt brake are equipped in clutch tension spring fixing seat 16
The lower end of frame tension spring 14 is connected on the belt brake frame 12 in 13 left side of belt brake frame rotation fulcrum.
The clutch lever 1 is mounted in the grass trimmer rack of the top of belt 11.
In the grass trimmer rack for the lower section that the clutch tensioning bracket 7 is hinged on belt 11, belt brake frame 12 is hinged on
Clutch is tensioned in the grass trimmer rack on the right side of bracket 7.
The clutch hand handle 1 is rotated around clutch hand handle rotation fulcrum 2;The both ends of clutch flexible shaft 3 are separately connected clutch hand
1 and clutch tension spring 6, the other end of clutch tension spring 6 is connected on clutch tensioning bracket 7;Clutch flexible shaft 3 is mounted on two clutches
On flexible axle support 4;Clutch is tensioned bracket 7 and rotates around clutch tensioning bracket rotation fulcrum 8;Brake shoes 15 is fixed on belt brake
