Problems solved by technology

[0003] The lawn mowers widely used in the market now mainly have the following problems: when shifting gears, it is necessary to take out the positioning pin first, turn the handle to adjust it to a predetermined gear, and then insert the positioning pin into the gear. It is very inconvenient; moreover, the machine will vibrate greatly during the working process, causing the positioning pin to not stay in the desired gear position reliably and stably, so that the gear position may fall off or jump gears during use.
At present, there is no lawn mower that can effectively solve the above problems

Embodiment Construction

[0045] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0046] see Figure 1 to Figure 3 , the multi-gear handle mechanism includes a handle, a shift member and a locking mechanism.

[0047] Wherein, the shifting member is used for setting multiple gears of the handle mechanism, and the locking mechanism is used for automatically engaging with multiple gears of the shifting member, so as to realize the fixing and adjustment of the gears.

[0048] The various components of the multi-gear handle mechanism are described in detail below:

[0049] As a preferred solution, the handle includes two connecting rods 1a, 1b, and a handle rotating shaft 2, the handle rotating shaft 2 is used to connect the ends on the same side of the two connecting rods 1 to form a whole that can move simultaneously. The ends on the other side of the two connecting rods are provided with a convenient gripping structure...

Abstract

The invention discloses a multi-gear handle mechanism and a lawn mower comprising the same. The multi-gear handle mechanism comprises a handle, and is characterized by further comprising a multi-gear shifter, and a locking mechanism automatically clamped to gears of the shifter to fasten or adjust the handle is disposed on the handle. The lawn mower comprising the multi-gear handle mechanism comprises a main mower unit, and is characterized in that the handle is rotatably connected with the main mower unit through a rotary shaft of the handle. The multi-gear handle mechanism and the lawn mower comprising the same have the advantages that the locking mechanism and the multi-gear shifter can be automatically locked, an operator can adjust the gears of the lawn mower easily and conveniently, gear locking is accurate and reliable, and convenience, flexibility and reliability in use are greatly improved.

Description

technical field [0001] The invention relates to a handle mechanism and a lawn mower including the handle mechanism, in particular to a multi-gear handle mechanism and the lawn mower including the multi-gear handle mechanism; it belongs to the field of electric tools and their auxiliary mechanisms. Background technique [0002] The lawn mower is a kind of power tool that is more commonly used. People have put forward higher and higher requirements for its convenience and flexibility, and its handle plays an extremely important role in improving the convenience of the lawn mower. We hope that when the handle is in different positions of the lawn mower, it can perform various functions such as mowing operation, weeding and folding storage. [0003] The lawn mowers widely used in the market now mainly have the following problems: when shifting gears, it is necessary to take out the positioning pin first, turn the handle to adjust it to a predetermined gear, and then insert the p...
