Includes a set to drive Clutch drum of the shaft! A centrifugal pivoting member provided at the output end of the motor and located inside the clutch drum, and the cutting blade driven at the end by the centrifugal pivoting member being clutchably coupled with the clutch drum. The clutch drum for coupling the blade to drive the shaft Please refer to the third and fourth figures, which includes a driving bowl (20) and a connecting rod (30), wherein the driving bowl (20) is a cylindrical bowl, and a knot is formed on the end surface of the bowl. : The hole (21), the flail rod (30) is a rod body provided with a polygonal hole (3i) for combining the blade drive shaft, and one end of the connecting rod (30) forms a ring coupling flange ( 3 2), and one end forming the coupling flange (3 2) is vertically inserted into the coupling hole (2 workers) that drives the bowl (20), and the coupling flange (3 2) is welded to the coupling hole (2 1) ) Will drive the bowl (20) and the connecting rod (30) Because the clutch drum is welded by two parts, the strength of the coupling between the two parts is insufficient, and the connection between the connecting rod (30) and the driving bowl (20) is not good due to the welding process. Shaking occurs during transmission, in addition to the poor transmission efficiency, and the insufficient strength of Wang and U Su 4 M283503 is more likely to cause overall damage. [New content] Due to the existing clutch drum, there will be insufficient strength and use. "It is easy to produce a shaking spoon", this creation proposes a clutch drum, which is a forged one-piece technical method to solve the aforementioned problem. In order to achieve the above purpose, this creation is provided with a driving bowl portion, with the middle of the driving bowl 2 facing outward A vertical-body extension-forming-connecting portion is provided with a polygonal hole for connecting the blade driving shaft in the connecting portion.

In the use of this creation, the blade drive shaft of the lawnmower is inserted through the connection part, and the centrifugal pivoting member that drives the bowl for the direct drive of the motor is combined. Because the connection part of the creation combined with the blade drive shaft is integrally driven by the bowl The extension of the part is therefore better in overall strength and high coaxiality, which makes it vibrate and deviate during driving operation, and is less likely to be damaged. [Embodiment] This creation is a clutch drum. Please refer to the first and first ^-'diagrams. The fish-man assembly is integrally forged and is provided with a driving bowl portion σ bowl portion (1 0). A cylindrical bowl-shaped body, and an accommodating groove (1 1) is formed on the upper Π 4, and the driving bowl part (i is a cylindrical straight body extended to form a connecting part (i 2), the connecting part: The middle hangs outwards-at the driving force of the bowl (the circular force 2 protruding outwards between the 10 ″) (= 1) and-from the reinforced body (work 2 i) Xiao extended 22), the connecting portion ( 12) Inside is provided with a multi-purpose self-drying stem (1 evening corner hole (1 2 3) 5 M283503 When this creative use is made, the polygonal hole (1 2 3) of the connecting portion (1 2) is combined with the lawn mower The blade drives the shaft, and the accommodating groove (1 1) for driving the bowl (1 0) is used for accommodating the centrifugal pivoting member provided at the output end of the motor. Because this creation is forged integrally, the bowl (1 0) and the connecting part (1 2) have high coaxiality, do not shake and sway when rotating, and have high strength and are not easy to damage.
