Clutch, electric tool with clutch, gardening tool with clutch and food waste processor with clutch

Abstract

The invention provides a clutch. The clutch comprises a supporting piece connected with a rotating shaft, two clutch assemblies and elastic pieces cooperating with the clutch assemblies, each clutch assembly comprises two clutch blocks which are arranged in the axial direction, the four clutch blocks of the two clutch assemblies are arranged symmetrically relative to the axial arrangement direction of the clutch blocks and the clutch movement direction correspondingly, and the four clutch blocks are the same in structure. Therefore, when the clutch is manufactured, mold making only needs to be performed for one clutch block, then the four same clutch blocks can be configured as one clutch, so that molds are simplified, the mold cost is saved, and then the manufacturing cost of the clutch is reduced; and the clutch blocks provided by the clutch each have a hollow structure and a cavity portion so that the clutch blocks can be made into various complex structures to be applied to different occasions, the supporting piece is clamped between the upper clutch block and the lower clutch block of each clutch assembly, so that limiting of the supporting piece in the up-down direction is facilitated, and a quite good safety protection effect is achieved.

Description

technical field [0001] The invention relates to a clutch and an operating machine with the clutch, in particular to a centrifugal clutch and an electric tool, a garden tool and a food waste disposer with the same. Background technique [0002] The clutch is similar to a switch, which engages or disengages the power transmission function, or performs speed limit protection by triggering the switch. The active part and the driven part of the clutch mechanism can be temporarily separated and then gradually engaged. Generally, rigid connection cannot be adopted between the driving part and the driven part of the clutch. [0003] Clutches on the market are mostly the structure in which the left and right clutch blocks are connected by extension springs or the left and right clutch blocks lean against the support block and are connected by extension springs. However, in some specific structures, we need to make the structure of the clutch block more complex in order to achieve ce...

AI Technical Summary

Problems solved by technology

However, in some specific structures, we need to make the structure of the clutch block more complex in order to achieve certain functional effects of the clutch. For example, we need to empty the middle of the clutch block to add other structures, which will make the mold difficult to make. Or it can't be done at all, we need to improve existing technologies to meet more diverse requirements
