发明名称 Combination weeding tool
摘要 A weeding tool with a combination of attachments integrated with a fulcrum to remove specific types of weeds based on their root structure. The attachments remove weeds whose roots are characterized as lengthy single-type roots, medium-depth bushy-hair type roots and near-surface vine-type roots. A fulcrum slidably attached to the tool handle ergonomically assists the gardener in extracting weeds by limiting angular rotation of the handle. The fulcrum may be used to apply foot pressure in penetrating hard soil. The fulcrum slides on the tool handle with respect to the end of the lifting blade to vary its penetration depth and is used for extracting single-type weed roots at different depths. The multiple-tine rake rotatably attached to the fulcrum is snapped into position and spring-biased to remain in position for extracting weeds having medium-depth bushy roots. The cultivator bar rotatably attached to the fulcrum is snapped into position for near-surface weed removal or general soil tilling. A crevice blade, rotatably attached to the fulcrum removes weeds between the gaps of patio paving blocks and the like, is snapped into position for this task. Most of these attachments can be combined onto one tool or other combinations integrated with the slidably attached fulcrum.
