The movable self-locking mechanism further comprises a first pin shaft 212, a first pin shaft 212 is inserted into the chassis connecting part 211, the other end of the first pin shaft 212 penetrates through one end of the chassis connecting part 211, a return rotating shaft 213 is sleeved on the middle side of the outer part of the first pin shaft 212, a second pin shaft 214 is inserted into the movable outer sleeve 112, one end of the second pin shaft 214 penetrates through the chassis connecting part 211 and the first pin shaft 212 and extends to the outer part of the other end of the movable outer sleeve 112, sliding grooves matched with the second pin shaft 214 are formed in the return rotating shaft 213 and the chassis connecting part 211, a movable ring 215 is sleeved on the outer part of the return rotating shaft 213 on one side of the second pin shaft 214, a notch matched with the second pin shaft 214 is formed in the movable ring 215, a spring 216 is sleeved on the outer part of the return rotating shaft 213, and two ends of the spring 216 are respectively welded on the movable ring 215 and the return rotating shaft 213, so that the second pin shaft 214 is driven to move together when the movable outer sleeve 112 moves, thereby make spring 216 take place to resume deformation and resume deformation to carry out the auto-lock to second round pin axle 214, thereby lock the position of taking off the connecting piece 111 that absorbs water, make the device can carry out the auto-lock.

All the cover is equipped with flat pad 223 on eight groups of shoulder bolt 224's the outside, all has locknut 222 through threaded connection on one side of eight groups of shoulder bolt 224 outside, adopts this kind of design to be convenient for make spacing to shoulder bolt 224, avoids it to take place to drop.

The movable sleeve 112 and one end of the movable plate 217 are fixedly connected with the pedal 221, and the outer portion of the pedal 221 is arc-shaped, so that the movable plate 217 and the movable sleeve 112 can be conveniently stepped on.

The elastic retainer ring 311 is clamped on one side of the outer portions of the first pin shaft 212 and the second pin shaft 214, and the first pin shaft 212 and the second pin shaft 214 are further limited by the design, so that the positions of the first pin shaft 212 and the second pin shaft 214 are more stable.

The working principle is as follows: when the device is used, the water absorption rake and the water absorption rake connecting piece 111 are installed through the chassis connecting piece 211 and the floor washing machine, and when the water absorption rake needs to be lifted, the water absorption rake connecting piece 111 is only required to be lifted.

When the water sucking rake connecting piece 111 needs to be lifted, only the pedal 221 on the movable plate 217 is stepped to one side, when the pedal 221 on the movable plate 217 is stepped, the movable plate 217 rotates around the limiting rotating shaft 218 because the chassis connecting piece 211 is in a fixed state, when the movable plate 217 rotates around the limiting rotating shaft 218, the limiting shaft 219 can be driven to move together, when the limiting shaft 219 moves, the limiting shaft 219 is inserted into the movable outer sleeve 112, so that the movable outer sleeve 112 is supported, one ends of the four groups of guide brackets 220 are movably connected to the chassis connecting piece 211, the other ends of the four groups of guide brackets 220 are movably connected to the movable outer sleeve 112, when the movable outer sleeve 112 moves, the angles of the four groups of guide brackets 220 are changed, and therefore the movable outer sleeve 112 is limited, and the movable outer sleeve 112 moves upwards.

When the movable outer sleeve 112 moves, the second pin shaft 214 is inserted into the movable outer sleeve 112, and drives the second pin shaft 214 to move together, when the second pin shaft 214 moves, the second pin shaft 214 is guided by the notch on the chassis connecting part 211, so that the second pin shaft 214 approaches to one side of the return rotating shaft 213 to extrude the spring 216, and simultaneously the return rotating shaft 213 rotates around the first pin shaft 212, and then the movable outer sleeve 112 continues to move, when the second pin shaft 214 passes through the middle side of the notch on the chassis connecting part 211, the second pin shaft 214 moves to the side away from the return rotating shaft 213, at this time, the return rotating shaft 213 continues to rotate, and simultaneously the recovery part of the spring 216 deforms, so that the second pin shaft 214 is clamped at the other end of the chute on the chassis connecting part 211, at this time, the spring 216 is in a deformation state, thereby always extruding the movable ring 215 to extrude the second pin shaft 214, thereby restraining the second pin 214 and thus the removal sleeve 112.

When the subsequent needs to be removed, the movable outer sleeve 112 can be moved downwards by stepping on the pedal 221 on the water absorption rake connecting piece 111, and meanwhile, the return rotating shaft 213 is rotated again, so that the second pin shaft 214 is restored to the initial position of the chute on the chassis connecting piece 211, and the resetting and the limiting are completed.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
