sequence of mechanical actions of the whole device:

when the vehicle starts to work, the starting motor 60 drives the driving shaft 59 to rotate, the driving shaft 59 rotates to drive the conversion sleeve 58 to rotate, the conversion sleeve 58 rotates to drive the movable sleeve 66 to rotate through the conversion gear 61 and the movable gear 62 so as to drive the wheel shaft 38 to rotate, the wheel shaft 38 rotates to drive the wheels 32 to rotate, the wheels 32 rotate to drive the main box body 10 to move forwards, the wheel shaft 38 rotates and simultaneously drives the centrifugal wheel 89 to rotate, the centrifugal block 34 moves outwards under the action of centrifugal force, the block slide block 39 moves leftwards under the action of the magnetic attraction force of the centrifugal block 34 against the action of the block spring 37 and pulls the baffle pull rope 44, the baffle 41 moves backwards under the action of the pull force of the baffle pull rope 44 against the thrust of the baffle spring 43 so as to connect the output cavity 13, the wheel shaft 38 rotates to output paint, the paint in the paint cavity 17 enters the output cavity 13 through the paint through cavity 12, and the paint finally falls to the road through the output cavity 13, at this time, the width of the sign line is the distance between the inner end surfaces of the width plates 14, and the main casing 10 moves forward to draw a rectangular sign line on the road as a straight portion of the arrow sign line.

After the straight line portion is divided, the switching button 22 is pressed against the urging force of the button spring 24, the switching button 22 moves downward and is locked by the button locking pin 25 and pulls the switching cord 20, the switching dial 69 moves rightward against the urging force of the switching dial spring 70 under the pulling force of the switching cord 20 to disengage the switching gear 61 from the moving gear 62, the main body 10 stops moving forward, the switching gear 61 and the moving gear 62 disengage from each other and simultaneously engage the switching gear 61 with the fixed gear 57, the switching sleeve 58 rotates to drive the fixed gear shaft 71 to rotate by the switching gear 61 and the fixed gear 57, the fixed gear shaft 71 rotates to drive the intermediate bevel gear shaft 80 to rotate by the forward bevel gear 78 and the intermediate bevel gear 79, the intermediate bevel gear shaft 80 rotates to drive the reverse bevel gear shaft 83 to rotate by the intermediate bevel gear 79 and the reverse bevel gear 84, the reverse gear shaft 83 rotates in the opposite direction to the fixed gear shaft 71, the reversing gear shaft 83 rotates to drive the reversing intermediate shaft 72 to rotate through the reversing gear 82 and the reversing gear 73, the reversing intermediate shaft 72 rotates to drive the adjusting sleeve 85 to rotate, the adjusting sleeve 85 rotates to drive the adjusting intermediate shaft 30 to rotate through the driving intermediate gear 86 and the driven intermediate gear 87, the torsion spring 40 starts to accumulate force, the adjusting intermediate shaft 30 rotates to drive the width screw 16 to rotate through the driving adjusting gear 29 and the driven adjusting gear 27, the screwing directions of threads on the left width screw 16 and the right width screw 16 are opposite, the width screw 16 rotates to drive the width plate 14 to move outwards, and the distance of the inner end face of the width plate 14 is the length of the large end of the arrow.

When the left width plate 14 moves to the left to the lower side of the conversion slide block cavity 49, the conversion slide block 51 moves downwards under the action of the magnetic attraction force of the moving magnet 46 against the pulling force of the conversion spring 52 and is locked by the conversion locking pin 48, the conversion slide block 51 moves downwards to pull the moving pull rope 65 and the reversing pull rope 76, the moving disk 63 moves to the right under the action of the pulling force of the moving disk spring 64 against the pushing force of the moving disk spring 65 to re-engage the moving gear 62 and the conversion gear 61, the wheel shaft 38 starts to rotate again to drive the main box body 10 to move forwards, the reversing disk 74 moves leftwards under the action of the pulling force of the reversing pull rope 76 against the pushing force of the reversing disk spring 75 to engage the reversing gear 73 with the forward rotation gear 77, the rotation direction of the adjusting sleeve 85 changes, the width plate 14 starts to move inwards, the main box body 10 moves forwards while the width plate 14 moves inwards, paint is output and the width of the scribe line changes with the distance of the inner end surface of the width plate 14 to form the shape of an arrow, when the width plate 14 moves inwards to the innermost end of the stroke, the width plate 14 blocks the paint through cavity 12, the paint stops outputting, the marking of the arrow mark line is completed, and the motor 60 stops working.

When the width plate 14 moves inward to the innermost end of the stroke, the unlocking slider 55 moves downward against the pulling force of the unlocking spring 54 under the magnetic attraction of the moving magnet 46 and pulls the unlocking cord 53 and the button locking cord 18, the switching locking pin 48 moves rightward against the pushing force of the switching locking spring 47 under the pulling force of the unlocking cord 53 to unlock the switching slider 51, the switching slider 51 moves upward under the pulling force of the switching spring 52 to be reset, the moving cord 65 and the switching cord 76 are released, the switching disk 74 moves rightward under the pushing force of the switching disk spring 75 to be reset to enable the switching gear 73 and the counter gear 82 to be re-engaged, the moving disk 63 moves leftward under the pushing force of the moving disk spring 64 to be reset, the switching button 22 moves upward under the pushing force of the button spring 24 to be reset, the switching cord 20 is released, the switching disk 69 moves leftward under the pushing force of the switching disk spring 70 to be reset, the switching gear 61 and the moving gear 62 are re-engaged, the switching gear 61 and the fixed gear 57 are disengaged, the adjusting intermediate shaft 30 is reversely returned by the torsion spring 40, and the width plate 14 is outwardly moved to be returned.
