Embodiment approach 1

[0046] Please refer to Figure 1 to Figure 4 , this embodiment discloses a trimming machine 100, the trimming machine 100 includes a housing 110, an output shaft 120 extending out of the housing 110, a cutting element 130 mounted on the output shaft 120, and a guide mechanism partially arranged on the housing 110 150 , the guide mechanism 150 includes a trimming guide plate 140 for protecting the cutting element and a position adjustment mechanism for rotatably connecting the trimming guide plate 140 with the housing 110 . The position adjustment mechanism includes a lever 151 that can slide up and down along the casing 110 and a connecting assembly that can be driven by the lever 151 and connected with the trimming guide plate 140. Transitions between an open position and a stowed position away from the cutting element 130 . Wherein, the cutting element 130 is a cutting wire or a cutting tool.

[0047]The trimming guide plate 140 has a baffle portion 143 capable of protecti...

Embodiment approach 2

[0053] The difference from Embodiment 1 lies in the specific structure of the guide mechanism.

[0054] Please refer to Figure 10 , as an extended implementation of Embodiment 1, a connecting piece 242 is fixed in the middle of the trimming guide plate 240, and the guide mechanism 250 includes a first node 253 fixed on the housing 110 and a first node 253 that is rotatably connected to one end of the trimming guide plate 240. Two connecting pieces 255 . Wherein, the first node 253 is rotatably connected to the connecting member 242 , and the second connecting member 255 is rotatably connected to one end of the lever 251 . The combined connecting structure of the first node 253 and the second connecting member 255 constitutes a connecting component of the guiding mechanism 250 . When the lever 251 is lifted upward, it drives the second connecting member 255 to move upward. At this time, the second connecting piece 255 drives one end of the trimming guide plate 240 to lift, ...

Embodiment approach 3

[0056] The difference from Embodiments 1 and 2 is that the guiding mechanism 350 is a four-bar mechanism.

[0057] Please refer to Figure 11 and Figure 12 , the guide mechanism 350 includes a first node 353 fixed on the housing 110, a third node 356, a first connecting piece 354 rotatably connected to the first node 353, and a third connecting piece rotatably connected to the third node 356 357 , the second connecting piece 355 rotatably connected to one end of the trimming guide plate 340 and the fourth connecting piece 358 rotatably connected to one end of the lever 351 . Wherein, the second connecting member 355 , the third connecting member 357 and the fourth connecting member 358 are rotationally connected. A second node 341 that can be rotatably connected to the first connecting member 354 is disposed in the middle of the trimming guide plate 340 . The combined connection structure of the first node 353 , the third node 356 , the first connecting member 354 , the se...

Abstract

The invention discloses an edge trimmer. The edge trimmer comprises a shell, an output shaft, a cutting element and a guide mechanism, wherein the output shaft protrudes out of the shell, the cutting element is arranged on the output shaft, and the guide mechanism is arranged on the shell; the guide mechanism comprises an edge trimming guide plate and a position regulating mechanism, wherein the edge trimming guide plate is used for protecting a cutting element, the position regulating mechanism is used for enabling the edge trimming guide plate to rotationally connect with the shell and comprises a lever and a connecting component, the connecting component is driven by a lever and is connected with the edge trimming guide plate, and the connecting component is driven to convert the edge trimming guide plate between an opening position and a retraction position when the position of the lever is converted. According to the edge trimmer, the edge trimming guide plate is located on the opening position by an operating lever so as to protect the cutting element from being damaged when edge operating environments, such as groove edges or roadsides, are met, and the edge trimmer has a guide function; furthermore, when the edge trimmer meets a flat operating environment, the guide mechanism enables the edge trimmer guide plate to be in the retraction position by the operating lever, so that the cutting element can operate in an unimpeded way.

Description

technical field [0001] The invention relates to garden tools, in particular to a trimmer. Background technique [0002] An edge trimmer is a common garden tool, mainly used for trimming or ditching the lawn. The edge trimmer includes a motor and a cutting element connected to the output shaft of the motor. Usually, the cutting elements are vertically arranged to achieve edge trimming or ditching. When the motor starts, the cutting element can be driven to trim or ditch. However, it has been found in actual use that when the lawn is trimmed, its working environment is often on the edge of a step such as a ditch or a roadside. During operation, the edge trimmer is easy to cause the cutting element to collide and cause damage due to the operation or the edge of the ditch or the edge of the roadside step itself. Contents of the invention [0003] Based on this, a trimming machine is provided that can guide the trimming operation while protecting the cutting element, so as to...
