CN203353077U - Clutch handle structure of mini-tiller - Google Patents

Abstract

The utility model discloses a clutch handle structure of a mini-tiller. The clutch handle structure of the mini-tiller comprises a clutch handle arranged on an armrest rod. The clutch handle structure of the mini-tiller is characterized in that a limiting structure is arranged between the clutch handle and the armrest rod, the limiting structure comprises a limiting clamp spring, a limiting clamp spring shaft, a resetting torsional spring and a limiting block, the limiting block is fixed to the armrest rod, the limiting clamp spring and the resetting torsional spring are fixed to the clutch handle through the limiting clamp spring shaft, the limiting clamp spring and the resetting torsional spring are connected with each other, and a limiting hole used for fixing the limiting clamp spring is formed in the limiting block. The clutch handle structure of the mini-tiller improves the safety coefficient in the process of operation and reduces danger.

Description

Mini-size tillage machine clutch handle structure

Technical field

The utility model relates to a kind of mini-size tillage machine clutch handle structure.

Technical background

Thereby traditional mini-size tillage machine clutch handle is all to make the machine work that starts to go into operation by directly pressing clutch handle.But because the user after ato unit, also not doing the preparation of ploughing in cultivated machine process, and as clothing or the careless clutch handle of pressing of people, make machine that work has occurred, if this produces great potential safety hazard, be not suitable for the hommization requirement, be difficult to reach the mower job requirement.

The utility model content

The purpose of this utility model is to provide a kind of mini-size tillage machine clutch handle structure, has improved the safety coefficient in the operating process, reduces dangerous.

To achieve these goals, the technical solution of the utility model is as follows:

Mini-size tillage machine clutch handle structure, comprise the clutch handle be arranged on bar, it is characterized in that: between clutch handle and bar, be provided with position limiting structure, described position limiting structure comprises spacing jump ring, spacing jump ring axle, reduction torsion spring and limited block, described limited block is fixed on bar, and described spacing jump ring axle is fixed in spacing jump ring, reduction torsion spring on clutch handle, described spacing jump ring and reduction torsion spring are connected to each other, and described limited block is provided with the spacing hole fixing for spacing jump ring.

The beneficial effects of the utility model:

Thereby traditional mini-size tillage machine clutch handle of comparing is all to make the machine work that starts to go into operation by directly pressing clutch handle, owing to being provided with spacing jump ring and limited block, when the user unclamps clutch handle and does not work, clutch handle separates with bar, spacing jump ring rotates to an angle under the effect of reduction torsion spring, and be limited in the limited block on bar, thereby upwards withstood clutch handle, can not be closed downwards.When the user starts working, must first pull away limited block to spacing jump ring, clutch handle just can be pressed, and machine can be started working.Produced thus composite move, this composite move must just can complete in conscious operation, avoided as clothing or people because of carelessness by clutch handle, make machine that work occur, produce great potential safety hazard, make mini-size tillage machine in use safer, hommization more, operator's operation is lighter.

As from the foregoing, the utility model has improved the safety coefficient in the operating process, reduces dangerous.

In order further to explain the technical solution of the utility model, below by specific embodiment, the utility model is elaborated.

The accompanying drawing explanation

Fig. 1 is separation schematic diagram of the present utility model.

Fig. 2 is closed schematic diagram of the present utility model.

Embodiment

As depicted in figs. 1 and 2, a kind of mini-size tillage machine clutch handle of the utility model structure, comprise the clutch handle 2 be arranged on bar 1, it is characterized in that: between clutch handle 2 and bar 1, be provided with position limiting structure, described position limiting structure comprises spacing jump ring 3, spacing jump ring axle 4, reduction torsion spring 5 and limited block 6, described limited block 6 is fixed on bar 1, described spacing jump ring axle 4 is by spacing jump ring 3, reduction torsion spring 5 is fixed on clutch handle 2, described spacing jump ring 3 and reduction torsion spring 5 are connected to each other, described limited block 6 is provided with for the fixing spacing hole of spacing jump ring 3.

The foregoing is only an embodiment of the present utility model, not to the restriction of this case design, all equivalent variations of doing according to the design key of this case, all fall into the protection domain of this case.

Claims (1)

1. mini-size tillage machine clutch handle structure, comprise the clutch handle be arranged on bar, it is characterized in that: between clutch handle and bar, be provided with position limiting structure, described position limiting structure comprises spacing jump ring, spacing jump ring axle, reduction torsion spring and limited block, described limited block is fixed on bar, described spacing jump ring axle is fixed in spacing jump ring, reduction torsion spring on clutch handle, described spacing jump ring and reduction torsion spring are connected to each other, and described limited block is provided with the spacing hole fixing for spacing jump ring.
