Description

Technical Field

[0001] This utility model belongs to the field of power tool technology, and specifically relates to an improved power tool handle. Background Technology

[0002] Power tools, especially handheld power tools such as sweepers, hair dryers, and pruning machines, are commonly used equipment in daily life and work. Conventional handheld power tools generally include a handle, a linkage, and a function unit. The handle is used for the user to hold and operate the tool, and it may have a power switch structure for starting and stopping the power tool's function unit.

[0003] In existing power tools, the power switch on the handle is generally a single switch that can start the tool with a single operation. This type of switch poses certain safety hazards and is prone to accidental activation, especially for power tools that are somewhat destructive, where accidental activation can easily cause injury.

[0004] Based on this, this application further designs and improves the handle structure in power tools. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model provides an improved power tool handle. The switch structure on the handle is a dual-operation switch structure, requiring two steps to start the tool, thus avoiding accidental activation. It is also suitable for one-handed operation and is convenient to use.

[0006] The present invention is solved by the following technical solution.

[0007] An improved power tool handle includes a handle body, on which a movable operating element is provided, and on the other side of the handle body opposite to the operating element, a pressable switch element is provided; an interference structure exists between the operating element and the switch element, such that the switch element can only be pressed after the operating element is moved; the handle body is provided with an elastic reset element for resetting the operating element and the switch element.

[0008] The handle structure in this application employs a linked dual-operation switch structure. In use, after gripping the handle body, the thumb pushes the operating component, and then the other four fingers press down on the switch component to start the power tool, making operation convenient. Upon releasing the handle, both the operating component and the switch component reset under the action of the elastic reset component, preventing accidental activation.

[0009] In a preferred embodiment, the interference structure includes: a first structural member disposed in the inner cavity of the handle body and moving synchronously with the operating member; a second structural member disposed on the switch member and protruding towards the inner cavity of the handle body; the second structural member abuts against the first structural member, preventing the switch member from being pressed; the movement of the operating member causes the first structural member to move away from the second structural member. This structure is simple and compact, has good linkage, and is easy to operate.

[0010] In a preferred embodiment, the elastic reset member includes a first spring for resetting the operating member and a second spring for resetting the switching member, providing an elastic reset force.

[0011] In a preferred embodiment, a limiting plate is provided in the inner cavity of the handle body. The limiting plate is used to restrict the movement of the first structural member and avoid excessive movement.

[0012] In a preferred embodiment, the switch is rotatably mounted on the handle body via a pivot, and an anti-disengagement hook is provided on the side of the switch away from the pivot, allowing it to be easily pressed.

[0013] In a preferred embodiment, the outer surface of the operating member is provided with anti-slip ridges and protrusions to facilitate thumb-push operation.

[0014] In a preferred embodiment, the handle body is formed by assembling two half-shell structures, and the handle body also includes an electrical switch structure and a corresponding circuit structure.

[0015] Compared with the prior art, the present invention has the following advantages: it provides an improved power tool handle with a dual-operation switch structure that requires two steps to start the tool, thus avoiding accidental activation. It is also suitable for one-handed operation and is convenient to use. Attached Figure Description

[0026] See Figures 1 to 7 This utility model relates to an improved power tool handle, comprising a handle body 1, a movable operating element 2 on the handle body 1, and a pressable switch element 3 on the handle body 1 opposite to the operating element 2; an interference structure exists between the operating element 2 and the switch element 3, such that the switch element 3 can only be pressed after the operating element 2 is moved; the handle body 1 is provided with an elastic reset element for resetting the operating element 2 and the switch element 3; specifically, the elastic reset element includes a first spring 51 for resetting the operating element 2 and a second spring 52 for resetting the switch element 3, providing an elastic reset force.

[0027] Specifically, as shown in the accompanying drawings, the interference structure of this application includes: a first structural member 21 disposed in the inner cavity of the handle body 1 and moving synchronously with the operating member 2; a second structural member 31 disposed on the switch member 3 and protruding towards the inner cavity of the handle body 1; the second structural member 31 abuts against the first structural member 21, preventing the switch member 3 from being pressed; the movement of the operating member 2 causes the first structural member 21 to move away from the second structural member 31. This structure is simple and compact, has good linkage, and is easy to operate.

[0028] Furthermore, in this application, a limiting plate 26 is provided in the inner cavity of the handle body 1.
