It includes a longitudinally-extended handle bar, at least one handle set on the handle bar, armrest connected with handle bar and working component set on the end portion of handle bar. The described handle at least includes two holding portions, in with first holding portion is connected with handle bar, the included angle between fist holding portion and handle bar is alpha, the second holding portion is connected with said first holding portions, and the included angle between them is beta, in which at least one of included angle alpha and included angle beta is adjustable, and another end of said second holding portion has a free tail end, if the first holding portion is matched with said armrest, the user can utilize single hand to make operation.

Description

Technical field [0001] The invention relates to a hand-held tool, in particular to a hand-held garden tool. Background technique [0002] At present, hand-held tools such as lawn mowers usually have a longitudinally extending handle rod. One end of the handle rod is provided with a working head, and the other end of the handle rod is provided with a shaped handle. Holding by hand, because the working head is located at the end of the long handle bar, the operator must use the strength of the arm muscles to hold the handle to maintain this operating state in order to keep the working head in contact with the ground. After working for a period of time, The operator will feel soreness in the arm muscles. In order to alleviate this situation, a second handle is provided on the handle bar of this type of tool in the known technology, which is used to provide the operator with the other hand to hold and hold both hands during operation. Operation, two-handed operation is usually less f...

AI Technical Summary

Problems solved by technology

In the operating mechanism, the first handle has only one holding part, and the user holds the same part no matter in the process of two-handed operation or one-handed operation, and the pivotal part connected to the second handle and the handle bar is the same as the first handle. The distance between the first handle is too small, and the grip part of the second handle is too far away from the above-mentioned pivoting part, so that when the user operates with both hands, it is difficult to adjust the second handle to a proper position. According to ergonomics The principle is that when operating with both hands, the user holds the first handle with one hand, and the second handle with the other hand. The distance between the hands is shoulder-width apart, and the grip part of the first handle is in a horizontal position, which is the most comfortable operating position. , therefore, this structure does not have a certain degree of comfort when operated with both hands; when operated with one hand, the second handle is adjusted to the second position to play the role of a support arm. Since each user's individual situation is different, the support arm The length requirements are also different, but the length of the second handle in this structure is not adjustable, and it does not take into account the comfort requirements as an arm rest. Therefore, the handheld operating mechanism that can be operated with one hand still exists. defect
