Handheld operating apparatus

Abstract

The invention discloses a handheld operating apparatus, which comprises a base (2), a cutting tool (10) detachably connected with the base, an operating rod (3) arranged on the base and roller wheels (8a and 8b) which are connected with the base and used for supporting the base, wherein the roller wheels are provided with a wheel shaft (9); the base is provided with a gear slot (24); the wheel shaft (9) is meshed in the gear slot and can be selectively locked at different places in the slot through a control piece (20); and the control piece further comprises an operating button (25) for manual control by an operator. Thus, the height of the roller wheels relative to the base can be adjusted effectively so as to realize cutting height adjustment.

Description

technical field [0001] The invention relates to a hand-held operating instrument, in particular to an electric cutting instrument. Background technique [0002] Generally, outdoor gardening cutting tools such as lawnmowers and mowers are provided with rollers that support tools and are used to walk on the ground. Such rollers are usually set in an adjustable form for adjusting The relative distance between the roller and the ground can change the height between the cutting tool and the ground plants to meet the mowing height. [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 do...

Problems solved by technology

[0005] The rollers of the lawnmower disclosed in the first previous application are respectively arranged on both sides of the protective cover, so when the height adjustment is performed, the rollers on both sides need to be adjusted to the corresponding height positions; The connecting shaft is pulled out, and then inserted into the corresponding holes on the protective cover and the bracket; such an operation 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
