One of both 5 and driving wheel 6.It further include reset spring A791, the reset spring A791 is set in clutch drive rod
In bracing wire between A731 and body 1.After unclamping corresponding clutch handle 71, reset spring A791 pushes clutch drive rod
A731 replys initial position, at this point, pull rod 733 then drives from driving wheel A741 far from main drive wheel 72, clutch far from body 1
Friction plate A781 is separated, interruption of power transmission.
As shown in fig. 7, it is described from driving wheel B742, driving wheel seat 75, push away seat 76 set on the inside of main driving wheel 72, it is described to push away
Seat 76 is set on hollow rotating shaft 77, is equipped with bearing 761 backwards to 1 side of body, the driving wheel seat 75 is set in bearing 761
On, the driving wheel seat 75 is equipped with wheel shaft 751 backwards to 1 side of body, and the wheel shaft 751 is connected to main biography by connecting shaft 721
Driving wheel 72, it is described to be sheathed on wheel shaft 751 from driving wheel B742, on the face opposite with driving wheel seat 75 from driving wheel B742
Equipped with the clutch friction plate B782 to match.
The other end of clutch drive rod B732 is equipped with push rod 734, and the push rod 734 is connected to across body 1 and pushes away on seat 76,
When corresponding clutch handle 71 of holding with a firm grip drives clutch drive rod B732 by bracing wire, clutch drive rod B732 is pushed away by push rod 734
It is dynamic to push away seat 76, and then push driving wheel seat 75 to close from driving wheel B742, by the cooperation of clutch friction plate B782 drive from
Driving wheel B742 rotation, it is described to cut the other of both grass wheel 5 and driving wheel 6 from driving wheel B742 driving.It further include resetting
Spring B 792, the reset spring B792 are set on the push rod 734 between clutch drive rod B732 and body 1.When release phase
After the clutch handle 71 answered, reset spring B792 pushes clutch drive rod B732 homing, at this point, the pulling of push rod 734 pushes away seat
76, i.e. driving 75 homing of wheel seat, clutch friction plate B782 separation, interruption of power transmission.
This double clutch control system is manipulated by two clutch handles 71, and is not influenced between each other, Ji Ketong
Shi Yunhang, can also isolated operation.
As shown in Fig. 8, Fig. 9, Figure 10：It further include the self-locking device of clutch handle 71；Pass through in the middle part of the clutch handle 71
Shaft is connected to grass mower pushing hands 2, and one end is formed with grip part 711, and the other end is formed with from lock section 712, described from lock section
712 side is equipped with compression bar 713, and two clutch handles 71 are oppositely arranged from lock section 712；The self-locking device includes self-locking body
81, two sides from lock section 712 equipped with compression bar 713,81 bottom of self-locking body and pedestal 82 are fixed on by pedestal 82
Elastic connection and towards far from being tilted from the side of lock section 712；The self-locking body 81 is equipped with recessed towards the middle side part from lock section 712
Slot 811, the top and bottom of groove 811 are respectively formed bayonet 812 and pressing plate 813；When a wherein clutch handle 71 of holding with a firm grip, certainly
Lock section 712 moves downward, and when compression bar 713 is pressed on pressing plate 813, bayonet 812 limits the compression bar of another clutch handle 71
713.Hold with a firm grip after two clutch handles 71, end moves down from the related compression bar 713 in lock section 712, into groove 811 after hold
Continuous final compression bar 713 is pressed on pressing plate 813 downwards, so that self-locking body 81 is moved towards close to the direction from lock section 712.At this point, loose
Open a clutch handle 71, can also be limited from the compression bar 713 on lock section 712 by bayonet 812 and can not homing, with this
It realizes self-locking function, liberates a hand.
As shown in Figure 9, Figure 10：The self-locking body 81 is equipped with slope 814 towards the top from 712 side of lock section.It can not
It holds with a firm grip two clutch handles 71 simultaneously, after clutch handle 71 of having held with a firm grip in the ban, the compression bar 713 of another clutch handle 71 can
To be blocked along 814 slide into grooves 811 of slope by bayonet 812.It avoids the need for unclamping the handle first held with a firm grip, then again
Two handles of holding with a firm grip are just able to achieve self-locking trouble.
Further include protective cover 9, the protective cover 9 cover clutch handle 71 from lock section 712 and shaft, the protective cover 9
