[0033] As Figures 1-7 shown, in an embodiment of the present application, a single-handed operation assembly and a snow blower provided with the single-handed operation assembly are provided, wherein the single-handed operation assembly comprises a handrail frame 10, a walking cable 20, a first clutch handle 30, a cage cable 40, a second clutch handle 50, a lock head 60 and a connecting assembly 70.

[0034] The handrail frame 10 is provided with a first handle pipe 11 and a second handle pipe 12. The first clutch handle 30 is rotatably arranged on the first handle pipe 11. The movable end of the first clutch handle 30 is separated from the first handle pipe 11. The first clutch handle 30 is connected with the walking cable 20 and continuously subjected to the pulling force of the walking cable 20. Pressing the first clutch handle 30 can pull the walking cable 20. Pressing the first clutch handle 30 means that the movable end of the first clutch handle 30 gradually approaches the first handle pipe 11. After releasing the first clutch handle 30, the walking cable 20 pulls the first clutch handle 30 to reset, at this time, the movable end of the first clutch handle 30 is separated from the first handle pipe 11.

[0035] The second clutch handle 50 is rotatably arranged on the second handle pipe 12. The second clutch handle 50 is provided with a lock hole 51. The movable end of the second clutch handle 50 is separated from the second handle pipe 12. The second clutch handle 50 is connected with the cage cable 40 and continuously subjected to the pulling force of the cage cable 40. Pressing the second clutch handle 50 can pull the cage cable 40. Pressing the second clutch handle 50 means that the movable end of the second clutch handle 50 gradually approaches the second handle pipe 12. After releasing the second clutch handle 50, the cage cable 40 also pulls the second clutch handle 50 to reset, at this time, the movable end of the second clutch handle 50 is separated from the second handle pipe 12.

[0036] The lock head 60 is movably arranged on the second handle pipe 12. After pressing the second clutch handle 50, when the lock hole 51 is aligned with the lock head 60, the lock head 60 will be clamped into the lock hole 51. The connecting assembly 70 is connected with the first clutch handle 30 and the lock head 60 respectively. The connecting assembly 70 is used to drive the lock head 60 out of the lock hole 51 after releasing the first clutch handle 30, so that the walking cable 20 pulls the second clutch handle 50 to reset.

[0037] In this scheme, when the operator presses the first clutch handle 30, the first clutch handle 30 pulls the walking cable 20, thereby controlling the snow sweeper to walk. When the operator presses the second clutch handle 50, the second clutch handle 50 pulls the cage cable 40, thereby controlling the cage to work. During pressing the second clutch handle 50, the lock head 60 is clamped into the lock hole 51, thereby locking the second clutch handle 50 on the second handle pipe 12. At this time, the operator does not need to press the second clutch handle 50, and the cage can also work continuously.

[0038] When the operator releases the first clutch handle 30, the first clutch handle 30 resets under the action of the walking cable 20, and the snow sweeper stops walking. At the same time, the connecting assembly 70 drives the lock head 60 out of the lock hole 51. At this time, the second clutch handle 50 resets under the action of the cage cable 40, and the cage also stops working.

[0039] The single-hand operation assembly and snow sweeper disclosed in the embodiment is locked on the second handle pipe 12 after the second clutch handle 50 is pressed, at this time, the operator only needs to press the first clutch handle 30 on the first handle pipe 11 to realize the walking and snow removing functions of the snow sweeper, that is, the single-hand operation can be realized, and the free hand can operate other functions of the snow sweeper. When the first clutch handle 30 is released, the connecting assembly 70 drives the lock head 60 to exit the lock hole 51, so that the second clutch handle 50 is also reset, at this time, the walking and snow removing functions are both stopped. In this way, the operation difficulty of the operator is reduced, the operation of the operator is more flexible when the snow sweeper is used, and the convenience of operation is improved.

[0040] In one embodiment, the connecting assembly 70 includes a connecting cable 71 and a reset member 72, the connecting cable 71 is arranged in the connecting sleeve, and the two ends of the connecting cable 71 are connected with the first clutch handle 30 and the lock head 60 respectively. The reset member 72 is used to apply an elastic force to the lock head 60 to reset the lock head 60 after the connecting cable pulls the lock head 60. The lock head 60 is provided with an inclined surface 61 matched with the second clutch handle 50. The connecting assembly 70 further includes a first mounting seat 73 mounted on the second handle pipe 12, the lock head 60 is movably matched with the first mounting seat 73, the inclined surface 61 is located outside the first mounting seat 73, and the reset member 72 is arranged in the first mounting seat 73. The reset member 72 is a spring.

[0041] If the first clutch handle 30 is pressed on the first handle pipe 11 by the operator, the lock head 60 is also clamped in the lock hole 51 of the second clutch handle 50, and when the first clutch handle 30 is released, the walking cable 20 quickly pulls the first clutch handle 30 to reset it. In the process of rotating, the first clutch handle 30 pulls the connecting cable 71 to instantaneously pull the lock head 60 (toward the first handle pipe 11) to exit the lock hole 51, and after losing the limitation of the lock head 60, the second clutch handle 50 quickly rebounds and resets under the pulling force of the auger cable 40. At the same time, the lock head 60 resets under the action of the reset member 72.

[0042] By designing the inclined surface 61 on the lock head 60, in the process of pressing the second clutch handle 50, the edge of the ear plate of the second clutch handle 50 pushes the inclined surface 61 of the lock head 60, so that the lock head 60 is partially retracted into the first mounting seat 73, and the lock head 60 also abuts against the ear plate of the second clutch handle 50. When the lock hole 51 is aligned with the lock head 60, the lock head 60 is quickly clamped into the lock hole 51 under the action of the reset member 72, so as to realize the locking of the second clutch handle 50. In this way, the stability of the cooperation between the lock head 60 and the second clutch handle 50 is improved.

[0043] In one embodiment, in order to improve the overall structural strength of the handrail frame 10, the handrail frame 10 is provided with a connecting pipe 13, which is connected to the first handle pipe 11 and the second handle pipe 12 respectively.

[0044] In one embodiment, the connecting pipe 13 is provided with a first lug 14 and a second lug 15, the walking cable 20 is arranged on the first lug 14, and the stirring cage cable 40 is arranged on the second lug 15. This structure design can fix the walking cable 20 and the stirring cage cable 40 on the handrail frame 10, so that the walking cable 20 and the stirring cage cable 40 can work normally.

[0045] In one embodiment, the two lug plates of the first clutch handle 30 are each provided with three first connecting holes 31, and the connecting head of the walking cable 20 is arranged in one of the first connecting holes 31. The two lug plates of the second clutch handle 50 are each provided with three second connecting holes 52, and the connecting head of the stirring cage cable 40 is arranged in one of the second connecting holes 52. The design of multiple first connecting holes 31 can make the connecting head of the walking cable 20 have multiple installation positions, so as to adaptively adjust according to the length of the walking cable 20. The design of multiple second connecting holes 52 is the same, and details are not repeated here.

[0046] In one embodiment, the first clutch handle 30 and the second clutch handle 50 have the same structure, which makes the first clutch handle 30 and the second clutch handle 50 have universality, and can reduce production cost and later maintenance cost.

[0047] In one embodiment, the first handle pipe 11 is provided with a second mounting seat 80, and the first clutch handle 30 is rotatably arranged on the second mounting seat 80.
