Problems solved by technology

When the rotary telescopic mechanism is deformed or invalid after repeated operations, when it needs to be replaced, the upper tube or lower tube integrally formed with it will also need to be replaced together, thus causing a waste of resources
In addition, some rotating telescopic mechanisms are equipped with metal parts and matching plastic parts, which will also make the assembly process relatively more cumbersome from the perspective of assembly.
In addition, some rotating telescopic mechanisms require one hand to operate the mechanism itself when the user performs rotation or telescopic operations, while the other hand needs to operate the handle or the head, which makes the operation more complicated and not convenient enough. and humanized

Abstract

The invention discloses a rotary telescopic mechanism for a grass trimmer. The grass trimmer comprises a head (1) and a handle (3) capable of rotating relative to the head. The handle comprises an upper tube (28), the head is provided with a lower tube (21), the rotary telescopic mechanism is detachably sleeved on the upper tube and the lower tube and comprises a rotary connector (23), a locking sleeve (22), a rotary part (24) and a rotary positioning part (26), the upper tube and the lower tube can relatively telescope and rotate, the locking sleeve (22), the rotary part (24) and the rotary positioning part (26) are sleeved on the rotary connector (23), the rotary part (24) is rotatably sleeved on the rotary connector (23) and fixedly sleeved on the upper tube (28), and the rotary positioning part (26) is slidably sleeved on the rotary part (24) and can rotate together with the rotary part (24). The rotary telescopic mechanism can be independently designed and manufactured, and is convenient, rapid and comfortable to operate.

Description

technical field [0001] The invention relates to a mower, in particular to a rotary telescopic mechanism of the mower. Background technique [0002] A lawn trimmer among garden tools includes a machine head, a handle part, and a rotating telescopic mechanism that can make the machine head and the handle part rotate relative to each other. An upper tube is arranged on the handle part, and a lower tube is installed on the handpiece. The above-mentioned rotating telescopic mechanism is arranged between the upper tube and the lower tube, which can not only adjust the telescopic length between the upper tube and the lower tube to adapt to users of different heights, but also can adjust the relative angle between the machine head and the handle to Adapt to the needs of different working states, for example, when the mower is mowing the lawn normally, the machine head is in a horizontal state; when the lawn mower trims the lawn, the machine head needs to be in a vertical state. ...
