The invention discloses a distance adjusting structure, belongs to the field of gardening tools, solves the problem that an adjusting mechanism in the prior art is unreliable and needs frequent operation, and adopts the technical scheme that the distance adjusting structure comprises a
machine body, a fixed cutter and a movable cutter, the fixed cutter and the movable cutter are arranged on the
machine body, and the movable cutter and the fixed cutter are oppositely arranged to form a shearing gap; the fixed cutter can move relative to the movable cutter to adjust the size of a
cutting gap, a distance adjusting transmission part is arranged on the
machine body and driven by an external driving part, the machine body is provided with a rotatable distance adjusting part, the outer contour of the distance adjusting part is a non-circular curve, the distance adjusting part is in transmission connection with the worm gear, and the worm gear is in transmission connection with the fixed cutter. The distance adjusting transmission part is configured to limit rotation of the distance adjusting part when no power is input to the external driving part, and the outer contour of the distance adjusting part abuts against the fixed cutter so that the fixed cutter can be driven to be close to or away from the movable cutter when the distance adjusting part rotates. The reliability of the distance adjusting function is improved, and the shutdown distance adjusting frequency and time are reduced.
