When telescopic component is to handle portion internal contraction, manually telescopic component is applied along telescopic component central axis towards handle The thrust in portion, telescopic component overcome the elastic force of third spring to handle portion internal contraction under external force, at the same time, hair The elastic potential energy of item release storage, clockwork spring driving annulus do rotation counterclockwise, ratchet and power input part synchronous rotary, Pawl slips over hook tooth, and power input part drives power output part rotation, power output part by the first transmission mechanism Collecting frame rotation is driven, wire body is rewound, after telescopic component collapses into handle portion inside completely, removed by the collecting frame of rotation External force, ratchet have the tendency that doing clockwise rotation, at this point, pawl is inserted into hook tooth, pawl limits ratchet around itself axis The rotation of line, annulus stop operating, so that power input part stops operating, power input part passes through the first driver Structure brakes power output part, and power output part stops operating, and further, collecting frame stops operating, collecting frame Stop the release to wire body, wire body constitutes a pair of of equilibrant force to the pulling force of third spring and the elastic force of third spring at this time, stretches The stopping of contracting component continues to stretch out outward.
