The invention relates to a light-small type hand hoisting traction
machine, and the body of the
machine comprises an external wall panel, a frame, a
ratchet casing and a leading chain block, wherein the external wall panel and the
ratchet casing are arranged on two sides of the frame separately, the leading chain block is arranged at the bottom of the frame, a driving mechanism is a double-geared driving mechanism, wherein a spline gear is arranged on the right side of a hoisting chain wheel, a major axis gear passes a center hole of the hoisting chain wheel and gear side of the major axis gear is rightward, a middle gear is arranged in a hole on the right side of the frame and engaged with the major axis gear and the spline gear, a
brake of a dragging chain is arranged on the left side of the major axis gear via a spline, wherein friction disks and a
ratchet are sleeved on the
brake seat, two friction disks are arranged on two sides of the ratchet, a
clutch spring is arranged between the
brake seat and arresting nut, the ratchet is engaged with a pawl which is fixed on the frame via a pawl pin, in a operating mechanism, a
handle and a
wrench are in split clamping structure, in a
tail ring limiting device, a chain through hole is arranged in the center of a positioning block, wherein a top lock is arranged at the end portion of one side of the block body, the top lock can be crewed into or crewed out from the chain through hole, and a latch groove of a collar bolt at the end of the chain is arranged at the lower end of the end portion of one side of the block body.
