ABSTRACT:
A gardening implement comprises a structure for fastening detachably a blade with a handle. The blade is provided at a fastening end with a deviation groove. The handle is provided at a fastening end with a fixation seat and a slide block slidably disposed in the fixation seat. The fixation seat is provided with a retaining slot. The slide block is provided with a retaining through hole. The blade is fastened with the handle such that the deviation groove of the blade is engaged with the retaining through hole of the slide block by virtue of the retaining through hole and the retaining slot being eccentric. As the slide block is activated to cause the retaining through hole to be concentric with the retaining slot, the deviation groove of the blade becomes disengaged with the retaining through hole to allow separation of the blade from the handle.
