The movable frame structure of the hand puller

Abstract

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are the two sides are completely dropped out of the ratchet teeth of the ratchet wheel, so that the rotary shaft can be withdrawn into the sleeve hole through the notch to form the movable rack structure.

Description

technical field [0001] The invention relates to a movable frame structure of a hand puller, in particular to a movable frame structure detachable from a fixed frame of the handle. Background technique [0002] According to the invention patent No. M320549 of China Taiwan Announcement, it discloses a kind of "separate cable puller (1)", which sets a movable frame 40 on a fixed frame 10, and by pulling the movable frame 40, and through the control panel 44 drives the ratchet 30 to rotate in one direction, thereby driving the rotating shaft 20 to rotate to perform cable retraction. [0003] The above-mentioned movable frame 40 is that the wing plate 41 fits on the rotating shaft 20 with the tracking hole 42, and then is sleeved on the rotating shaft 20 through the sleeve hole 52 of the locking plate 50, and is pivoted on the rotating shaft 20 through the locking plate 50, so that the wing plate 41 does not move In addition, the locking plate 50 is fixed on the wing plate 41 by...

AI Technical Summary

Problems solved by technology

[0004] However, although the feature that the wing plate 41 can be detached from the rotating shaft 20 has its functional properties, compared with the traditional handle structure, installing the locking plate 50 on the movable frame 40 will increase the cost and assembly man-hours. The lock plate 50 is often expanded outwards and deformed by bending, which will cause the sleeve hole 52 of the lock plate 50 to be easily detached from the shaft 20 in the axial direction, and the wing plate 41 will be easily detached from the shaft 20 through its gap 421 when the movable frame 40 is pulled. If the situation often occurs, the cable belt will often be interrupted when it is retracted, resulting in the problem that the efficiency of the cable retraction operation is not good.
