Flameout protection device for garden saw

Abstract

The invention provides a flameout protection device for a garden saw. The device includes a saw box, a saw blade is fixedly installed in the saw box through a driving rotating shaft, and a motor is arranged on the outer side of the saw box; the rotating shaft of the motor is fixedly connected with the driving rotating shaft of the saw blade, and one side of the saw box is internally provided with a saw slot in a concave mode; the side walls, on the front and back ends of the saw slot, of the saw box are provided with a protective plate moving cavity and a protective plate fixing cavity respectively; the inner end of the protective plate moving cavity is fixedly connected with one end of a tension spring, and the other end of the tension spring is movably hinged with the end face of one end of a protective plate, the protective plate is in an arc shape and is movably inserted in the protective plate moving cavity for connecting. According to the flameout protection device for a garden saw, the motor drives the saw blade to rotate at a high speed to trim garden foliage, and after trimming, the protective plate slides in the protective plate moving cavity outwards by dialing a handle; moreover, one end of the protective plate is inserted in the protective plate fixing cavity for connecting, and fixed in a limiting hole through a extrusion limiting column, and therefore the whole protective plate is covered outside the saw blade, so that the saw blade is protected when not in use.

Description

technical field [0001] The invention relates to the field of garden machinery and equipment, in particular to a flameout protection device for a garden saw. Background technique [0002] Garden machinery is mainly used for pruning and modeling of garden nurseries, flowers, green belts, etc. Most pruning machines use high-speed rotating cutterheads to trim branches and leaves. When not in use, the cutterheads are usually exposed. When the staff It is easy to be cut when accidentally touching the sharp edge of the cutter head, which has certain safety hazards. At the same time, the cutting edge of the cutter head is also relatively fragile. Random placement without protection will easily cause damage to the cutter head and shorten its service life. Reduced, resulting in an increase in cost, for this reason we propose a garden saw with a flameout protection device. Contents of the invention [0003] The object of the present invention is to provide a flameout protection devi...
