Description

technical field [0001] The invention relates to a hand-held operating device, in particular to a garden lawnmower. Background technique [0002] Generally, outdoor gardening cutting tools such as lawnmowers and lawn mowers are provided with rollers supported on the ground and used for walking. The relative distance between the ground, thereby changing the height between the cutting tool and the ground plants to meet the needs of mowing. [0003] For example, Chinese Patent Announcement No. 200953749 discloses a lawnmower with adjustable roller position, which includes a main body and a push rod, wherein the push rod part includes a handle and a telescopic rod connecting the handle and the main body, and the main body part includes There is an organic casing and a working head including a turntable and a nylon rope. A protective cover is provided outside the working head, and up and down adjustable rollers are respectively installed on both sides of the protective cover. Th...

Problems solved by technology

[0005] In the roller adjustment structure of the lawnmower disclosed in the first previous application, since the rollers are respectively arranged on both sides of the protective cover, when the height adjustment is performed, the rollers on both sides need to be adjusted to the corresponding height positions; and during the adjustment process It is necessary to pull out the connecting shaft first, and then insert it into the corresponding hole on the protective cover and the bracket; such an operation and installation procedure is very cumbersome and time-consuming, and does not use effective cutting operations

[0006] When the lawnmower disclosed in the second previous case is performing a cutting operation, its support seat is supported on the grass. The support seat has a wider support surface, so that the lawnmower can obtain a stable support. When the support seat When moving on the ground, there will be friction between the support surface and the ground, which will affect the operation and work efficiency, and the gear adjustment structure of its height is relatively complicated, and the operation is not convenient
