Embodiment 1

[0036] Such as Figures 1 to 3As shown, a resisting portion 81 is provided inside the middle panel assembly 8, and a chamfered block 5 is provided on the pin shaft 3. and the resisting portion 81 are sequentially arranged along the axial direction of the pin shaft 3, the chamfered block 5 is arranged closer to the second sleeve 2 than the resisting portion 81, and the coil spring 4 is arranged between the chamfered block 5 and the resisting portion 81. The spring in the compressed state, at this moment, the coil spring 4 has the active force that makes the pin shaft 3 move in the first pin hole, and the button 6 is arranged on the middle panel assembly, and the button 6 constitutes the force applying part in the present invention, and the button 6 One end is exposed outside the middle panel assembly, and the other end extends into the middle panel assembly. A sliding connection relationship is formed between the button 6 and the middle panel assembly in which the button 6 can ...

Embodiment 2

[0046] The structure is basically the same as that of Embodiment 1, except that the resisting portion 81 is arranged closer to the second sleeve 2 than the abutting portion II, such as Figure 4 As shown, the coil spring 4 at this time is a spring in a compressed state arranged between the abutting portion II and the abutting portion 81 . In this embodiment, the return spring 7 is a spring in a compressed state.

Embodiment 3

[0048] The structure is basically the same as that of Embodiment 2, except that: in the radial direction of the pin shaft 3, the abutment part IV64 is arranged closer to the pin shaft 3 than the abutment part III82, such as Figure 5 As shown, at this time, the return spring 7 is a spring in a stretched state, with one end fixedly connected to the abutment part III82 and the other end fixedly connected to the abutment part IV64.

Abstract

The invention provides a telescopic handrail adjusting structure capable of adjusting the length of a handrail. The telescopic handrail adjusting structure mainly comprises a sleeving structure and a middle panel assembly. The sleeving structure comprises a first sleeve and a second sleeve. A first plug pin hole is formed in the side wall of the second sleeve. A plurality of second plug pin holes are formed in the side wall of the first sleeve. The middle panel assembly is fixedly connected with the second sleeve. The middle panel assembly is provided with a hinge pin capable of moving axially. The hinge pin penetrates through the first plug pin hole in the axial direction. A spiral spring is connected between the middle panel assembly and the hinge pin and has acting force enabling the hinge pin to move in the axial direction. The hinge pin is provided with a stress part. The middle panel assembly is provided with a force exerting part matched with the stress part. The force exerting part can move in a reciprocating mode relative to the middle panel assembly and is provided with a force exerting portion. The invention further provides a telescopic handrail and a gardening tool.

Description

technical field [0001] The invention relates to the field of garden tools, in particular to a telescopic handrail adjustment structure, a telescopic handrail using the telescopic handrail adjustment structure and a garden tool using the telescopic handrail. Background technique [0002] At present, the common hand-push garden tools are human-propelled walking type. This kind of garden tools usually needs to adjust the angle of the handrail to adapt to the operation of crowds of different heights, which is troublesome. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a telescopic armrest adjustment structure capable of adjusting the length of the armrest. [0004] Another object of the present invention is to provide a telescopic armrest adopting the telescopic armrest adjustment structure. [0005] Another object of the present invention is to provide a garden tool using the telescopic handrail. [0006] In orde...
