Specific embodiment
The following is the specific embodiment of the present invention and combine accompanying drawing 1-4, technical scheme is further retouched
State, but the present invention is not limited to these embodiments.
A kind of rear tug device, includes cloth pushing shaft 1, and cloth pushing shaft 1 is by lower crank 2 and the connecting rod of more than and upper song
Handle 3 connects, and the upper crank 3 is fixed on mop axle 4, and fixed mount 5 is additionally provided with mop axle 4 and crank 6 is adjusted, described
Adjust crank 6 to be fixedly connected with mop axle 4, fixed mount 5 can be relatively rotated with mop axle 4, that is to say, that adjust crank 6 and follow
When mop axle 1 rotates, fixed mount 5 is not moved.Bar hole 7 is provided with crank 6 is adjusted, the one end for drawing wheel carrier 8 is hinged on bar
On shape hole 7, it is described draw wheel carrier 8 the other end be hinged with long-armed the 10 of tugboat crank 9, the axle portion short end 11 of tugboat crank 9 with consolidate
Determine frame 5 to be hinged, the tugboat 13 after the axle portion length end 12 of tugboat crank 9 is provided with, adjust and draw wheel carrier 8 in the bar shaped 7 for adjusting crank 6
Position on hole reaches the regulation for changing the action length realization for adjusting crank 6 to the rotating speed of rear tugboat 13.
Specifically, the rear tugboat 13 is arranged on the axle portion length end 10 of tugboat crank 9 by tugboat fixing screws 20, described
Tugboat fixing screws 20 are screwed onto on the end face at axle portion length end 10.
