Abstract

The invention relates to a shovel, in particular to a labor-saving shovel with a quickly replaceable shovel head. The technical problem is to how to design the labor-saving shovel with the quickly replaceable shovel head, the shovel head can be conveniently replaced, and people of different heights can use the shovel in a labor-saving mode. The labor-saving shovel with the quickly replaceable shovel head comprises a supporting rod provided with the detachable shovel head at one end, and an anti-skid holding sleeve fixedly arranged on the periphery of the outer side, far away from the detachable shovel head, of the supporting rod in a sleeving mode. The detachable shovel head makes contact with soil, a lever force application mechanism is treaded to move downwards, the lever force application mechanism moves downwards to drive the supporting rod to move downwards, the supporting rod moves downwards to drive the detachable shovel head to move downwards to be inserted into the soil, then the supporting rod is pulled to swing, so that the soil is shoveled out through the detachable shovel head; and through the effect of a clamping mechanism, the detachable shovel head is convenient to replace.

Description

technical field [0001] The invention relates to a shovel, in particular to a labor-saving shovel capable of quickly replacing the shovel head.
