The invention discloses a movable rack structure of a hand puller. When two side plates are pushed forwards to insert into ratchet teeth of a ratchet wheel, a resisting part of a locking part rotates by trigging the two side plates to drive the ratchet wheel; when the two side plates are backwards pulled, the resisting part of the locking part is separated to the outside of the ratchet teeth of the ratchet wheel; the two side plates can resist the peripheral surface of the rotary shaft through a circular-arc hole in the sleeve hole to swing along the shaft center of the rotary shaft, and a blocking edge is used for restraining the peripheral surface of the rotary shaft from separating from the circular-arc surface; when the two side plates are moved to the circular-arc surface of the sleeve hole to leave the peripheral surface of the rotary shaft, and a notch is aligned to the rotary shaft, the resisting part of the locking part is placed into the ratchet tooth of the ratchet wheel to block; the locking part is backwards pulled, so that the resisting parts are the two sides are completely dropped out of the ratchet teeth of the ratchet wheel, so that the rotary shaft can be withdrawn into the sleeve hole through the notch to form the movable rack structure.
