Lawn mower

Abstract

The invention discloses a lawn mower which comprises a housing (14) of the lawn mower and an extended operating bar, wherein the housing (14) comprises a longitudinally extended longitudinal shaft (x), a blade (15) extends out of the housing (14) along the longitudinal shaft (x), the extended operating bar comprises a connecting part (63), wherein, the lawn mower further comprises a connecting component (8) arranged between the housing (14) and the connecting part (63), the connecting component (8) comprises a locking device (9), and the locking device (9) comprises a locking position which can keep the connecting part (63) and the housing (14) static relatively and a release position which can lead the connecting part (63) to rotate around the longitudinal shaft (x) of the housing (14). The technical scheme can lead the lawn mower to be convenient to operate and have strong human-computer function when trimming side angles and other positions of a lawn.

Description

technical field [0001] The invention relates to a lawnmower, especially a lawnmower with an extended operating rod. Background technique [0002] In order to operate the hand-held lawnmower to repair the lawn more conveniently, most of the lawnmowers are equipped with an extended operating lever at present, such as a lawnmower with an extended operating lever disclosed on April 19, 1977 in U.S. Patent No. 4,018,037. The extension operating rod includes a connecting portion and a gripping portion. After the body of the lawnmower is connected to the connecting portion of the extending operating rod, it remains relatively stationary with the gripping portion. A switch is provided on the gripping portion. After the operating rod is extended, the connection part is electrically connected to the lawnmower, and the lawnmower can be controlled to work through the switch on the grip part. The positions of the body and extension lever of this mower are not adjustable and remain relat...

AI Technical Summary

Problems solved by technology

The positions of the body and extension lever of this mower are not adjustable and remain relatively stationary during the cutting process, causing the bench surface to block the extension when mowing some lawns with obstacles on them, such as the lawn under a park bench The operating lever prevents the lawnmower from cutting the lawn inside the bench, which is inconvenient to operate

[0003] In order to solve the above problems, U.S. Patent No. 6,874,303 disclosed a lawnmower with a movable extension operating lever on April 5, 2005. The extension operating lever can be pivotally adjusted relative to the position of the lawnmower body. The extension of the lawnmower The operating lever includes a transverse arm perpendicular to the body of the lawnmower and a grip portion extending from the arm perpendicular to the arm, the transverse arm is connected to the body of the lawnmower through a locking device, and the locking device can be moved position and locked position to select, when the locking device selects the active position, the grip part can swing freely in a plane perpendicular to the lawnmower blade, when the locking device selects the locked position, the lawnmower body and The handle is relatively static. Through this structure, the lawn mower can easily trim the lawn with obstacles such as benches above it. However, this structure still requires the operator to repair some special positions, such as the lawn on the edge of the wall. It is inconvenient to operate against the wall, and the man-machine function is weak
