Hand tools and their auxiliary handles

Abstract

The invention discloses a handheld tool and a sub-handle thereof. The tool comprises a tool body with an accommodating cavity therein, a motor arranged in the accommodating cavity, a switch for controlling the running of the motor, and a working component driven by the motor and extended outwards from the tool body; a main handle positioned at the back and a sub-handle positioned at the front and next to the work component are arranged on the tool body; the switch is positioned on the outer side of the sub-handle; the sub-handle comprises a sub-handle seat, a sub-handle cover, and a trigger positioned between the sub-handle seat and the sub-handle cover, wherein the trigger can deflect relative to the sub-handle seat. The sub-handle is simple in integral structure, less in parts, easy to assemble, more sensitive in triggering, and higher in reliability, and can be packed separately with the tool body as an independent demountable component, so as to greatly improve the packing quantity.

Description

technical field [0001] The invention relates to a hand-held tool and its auxiliary handle. Background technique [0002] Generally, the hand-held tool has an auxiliary handle for holding, and the operating position of the auxiliary handle can be held in three positions of left, middle and right according to the needs of the operator, so as to meet the requirements of comfortable operation. [0003] Existing auxiliary handle switch structure is generally more complicated, discloses a kind of hedge trimmer as European Patent Application Publication EP0214455, and this hedge trimmer is a kind of hand-held electric tool, and this tool is provided with main, auxiliary two handles, wherein auxiliary The handle is ring-shaped and has three gripping positions: left, middle and right, and a switch mechanism capable of triggering at the three gripping positions of the left, middle and right is installed on it. However, the trigger action of the switch mechanism provided in the auxili...

AI Technical Summary

Problems solved by technology

[0003] The structure of the existing auxiliary handle switch is generally more complicated, such as European patent application publication EP0214455 discloses a hedge trimmer, which is a hand-held electric tool , the tool is provided with two main and auxiliary handles, wherein the auxiliary handle is in the shape of a ring, has three gripping parts of left, middle and right, and is equipped with a trigger on the left, middle and right three gripping parts. switch mechanism

However, the trigger action of the switch mechanism provided in the auxiliary handle is transmitted through the steel rope. The steel rope needs multiple parts to support in the auxiliary handle, and the assembly is poor, resulting in a complex overall structure of the switch mechanism, low working reliability and high manufacturing cost

[0004] In order to solve the above problems, the applicant proposed the Chinese patent No. CN201957492, which is very convenient for assembly and production, and the cost is low. Three springs are respectively set in the three right gripping directions to make the trigger move in the left, middle and right directions. The structure is complex and there is room for further improvement.
