at this time, the two limiting blocks 12 are positioned in the annular groove 17 and are staggered with the two fan-shaped unlocking grooves 18 on the lower end surface of the lock sleeve 16; the positioning sleeve 7 drives the brace 21 to swing back to the initial position through the two fixture blocks 20 and the pull rod 19; then the lower ends of the two arc-shaped magnetic strips 42 respectively absorb the tiny iron garbage on the ground, and when the tiny iron garbage on the ground is completely absorbed to the lower ends of the two arc-shaped magnetic strips 42, the lower end of the picking device is suspended above the garbage can or above the garbage bag; then, the brace 21 is hooked upwards, so that the brace 21 drives the two fixture blocks 20 to move upwards along the second sliding chute 8 through the pull rod 19; when the two fixture blocks 20 contact with the top surface of the annular groove 17 in the lock sleeve 16, the two fixture blocks 20 which continue to move upwards drive the lock sleeve 16 to move upwards synchronously along the rotation limiting guide groove 40; when the bottom surface of the ring groove 17 in the lock sleeve 16 is contacted with the inclined surfaces of the two limit blocks 12 on the outer cylindrical surface at the lower end of the positioning sleeve 7, under the continuous action of the lock sleeve 16, the two limit blocks 12 respectively slide into the corresponding limit grooves 9 at the same time and are gradually contacted to limit the upward movement of the lock sleeve 16 along the rotation limit guide groove 40, and the limit spring 14 is compressed; the lock sleeve 16 pulls the two arc-shaped magnet strips 42 to respectively slide upwards along the corresponding arc-shaped guide rails 31 through the two thin steel wire ropes 23 fixedly connected with the lower end face of the lock sleeve; when the separating block 36 starts to contact with the inclined surface of the lower end of the arc-shaped magnet strip 42, the small iron garbage adsorbed at the lower end of the arc-shaped magnet strip 42 starts to be removed by the separating block 36 under the action of the pressure spring 38 which is always compressed; when the arc-shaped magnet strip 42 moves to the initial position, the driving spring 35 restores the original state, all small iron garbage adsorbed at the lower end of the arc-shaped magnet strip 42 is completely separated by the separating block 36 and falls into the garbage can, at the moment, the lock sleeve 16 just crosses the two limiting blocks 12 upwards, under the action of the limiting spring 14, the two limiting blocks 12 restore to limit the movement of the lock sleeve 16, the pull rod 19 drives the two arc-shaped clamping arms 28 to swing oppositely for a certain angle through the thin steel wire rope 23 and the arc-shaped driving strip 30, and the arc-shaped driving strip 30 deforms to a certain degree; then the acting force on the brace 21 is removed, under the restoring force of the arc driving strip 30, the two arc clamping arms 28 swing back to the initial positions, the arc driving strip drives the pull rod 19 and the brace 21 to return to the initial positions through the thin steel wire rope 23, and the work of picking up and separating the iron garbage is finished.

Traditional scheme of separation iron rubbish: the plastic sheet can be arranged on the outer arc surface of the lower end of the arc-shaped clamping arm 28, and the principle is as follows: the magnetic force of the arc magnet strip 42 sliding to the bottom of the arc clamping arm 28 can enable iron garbage to be adsorbed on the plastic sheet instead of the arc magnet strip 42 through the plastic sheet, the arc magnet strip 42 reset upwards loses adsorption on the iron garbage adsorbed on the plastic sheet, and the iron garbage can fall freely; the method for installing the plastic sheets enables the volume of the lower end of the arc-shaped clamping arm 28 to be larger, so that the arc-shaped clamping arm 28 is not beneficial to clamping common garbage in a shallow slit; and the utility model discloses in utilize the scheme of 36 special rubbish of shoveling of separation piece to enable 28 lower extremes of arc arm lock and be in less volume, more do benefit to pickup apparatus and get into and pick up the ordinary rubbish in the gap.

To sum up, the utility model has the advantages that: the garbage picking device in the utility model can not only pick up the garbage as the common picking device, but also pick up the tiny iron garbage; in the process from the state of being adsorbed on the arc-shaped magnet strip 42 to the state of being separated from the arc-shaped magnet strip 42, the iron refuse; in the whole process of picking up the iron tiny garbage, the iron tiny garbage can be picked up and separated only by grasping the picking device, an operator does not need to take down the iron tiny garbage from the lower end of the picking device with the other hand and throw the iron tiny garbage into the container, and the iron tiny garbage picking device is very convenient and fast to use; when the picking device picks up common garbage, the arc-shaped magnet strip 42 does not slide back and forth along the arc-shaped guide rail 31, thereby greatly reducing the abrasion of the arc-shaped magnet strip 42 and prolonging the service life of the arc-shaped magnet strip 42; in addition, when the picking device clamps the common garbage, the arc-shaped magnet block is not arranged at the lower end of the arc-shaped clamping arm 28 of the picking device, so that the volume of the lower end of the arc-shaped clamping arm 28 is relatively smaller, the picking device can clamp the common garbage in a shallow slit, and the use environment of the utility model is enlarged; when separating the iron garbage adsorbed on the arc magnet strip 42, the separating block 36 can completely separate the iron garbage adsorbed at the lower end of the arc magnet strip 42, so that the phenomenon that the small iron garbage enters the arc guide rail 31 to block the movement of the arc magnet strip 42 along the arc guide rail 31 is prevented, the abrasion between the arc magnet strip 42 and the arc guide rail 31 is avoided, and the service life of the arc magnet strip is prolonged.
