Step two: starting the output end of the third motor (311) to drive the first gear (312) to rotate, driving the second gear (314) to rotate by the first gear (312), driving the third threaded rod (315) to rotate by the second gear (314), driving the threaded sleeve (316) to move up and down by the third threaded rod (315), driving the containing frame (313) to move up and down under the limit of the limit sleeve (317) and the limit slide bar (318) by the threaded sleeve (316), driving the printer to move up and down by the containing frame (313) through the containing plate (411), driving the linkage bar (323) to move down by the first spring (324) when the containing frame (313) moves down, because the U-shaped plate (325) is not moved, when the linkage rod (323) moves downwards to contact the inner bottom of the U-shaped plate (325), the containing frame (313) continues to move downwards, at the moment, the linkage rod (323) is not moved in situ due to the blocking of the U-shaped plate (325), so that the linkage rod (323) drives the locking inserting rod (321) to move upwards, the locking inserting rod (321) moves upwards and is separated from the locking inserting hole (322), the first spring (324) is stretched when the linkage rod (323) moves upwards, the first spring (324) is stretched and deformed, the locking inserting rod (321) is separated from the locking inserting hole (322) when the universal wheel (412) descends to contact the ground, thereby make locking inserted bar (321) no longer lock hold board (411) to make and hold board (411) and printer can pull out this moment, thereby realized holding the automatic unblock of board (411), start third motor (311), third motor (311) drive holds frame (313) upward movement through third threaded rod (315), because the restoring force of first spring (324) this moment, thereby make first spring (324) drive locking inserted bar (321) and hold frame (313) downward movement through gangbar (323), thereby make locking inserted bar (321) peg graft again inside locking jack (322), to holding the automatic locking of board (411).
Step three: the lifting type containing self-locking assembly (3) drives the containing plate (411) to move downwards, the containing plate (411) moves downwards to drive the universal wheel (412) to move downwards to be in contact with the ground, at the moment, the lifting type containing self-locking assembly (3) is automatically unlocked, at the moment, the unlocking locking assembly (43) and the pushing plate (421) are pulled outwards, at the moment, because the third gear (425) and the fourth gear (426) are in a separated state, the pushing plate (421) drives the limiting rotating rod (423) to rotate through the sliding groove (422), when the pushing plate (421) rotates to a convenient pushing angle, the pushing plate (421) is pulled out in a direction away from the lifting type containing self-locking assembly (3), the pushing plate (421) drives the containing plate (411) to pull out in a direction away from the lifting type containing self-locking assembly (3), the limiting rotating rod (423) and the hemispherical pressing block (424) move forwards, when the hemispherical pressing block (424) moves forwards to be separated from the lifting type containing self-locking assembly (3), the two groups of second springs (427) push the limiting rotating rod (423) to be separated from the lifting type containing self-locking assembly (426), the second gear (423) in a direction away from the lifting type self-locking assembly (426), the second gear (426) is meshed with the fourth gear (423) in a direction away from the lifting type self-locking assembly (425) and the lifting self-locking assembly (425) respectively, because fourth gear (426) fixed connection is on square baffle (413) to make third gear (425) and fourth gear (426) relatively fixed, because spacing bull stick (423) and spout (422) limit sliding connection, thereby make push pedal (421) unable rotation under the spacing of spout (422) and spacing bull stick (423), thereby make the invariable convenient propelling movement of angle of push pedal (421), when push pedal (421) drive hold plate (411) and break away from over-and-under type and hold self-locking subassembly (3) completely, at this moment push pedal (421), hold plate (411) and universal wheel (412) constitution trolley, push hold plate (411) propelling movement to over-and-under type and hold self-locking subassembly (3) inside, when push pedal (421) drive hemisphere briquetting (424) contact over-and-under type hold self-locking subassembly (3) side wall, continue to promote push pedal (421), hemisphere briquetting (424) are close to each other under the extrusion of over-and-under the type of lift type subassembly (3) this moment, thereby make hemisphere briquetting (424) drive spacing bull stick (423) and are close to each other, limit spring (427) make second gear (423) compress and make fourth gear (427) to make and make third gear (423) compress and make and separate from each other, thereby fourth gear (427) compress and make up and hold the deformation, at this time, the holding plate (411) completely enters the lifting type holding self-locking assembly (3), at this time, the third gear (425) and the fourth gear (426) are separated so that the push plate (421) can be rotated, at this time, the push plate (421) is rotated to be vertical and locked through the locking assembly (43), so that the push plate (421), the holding plate (411) and the lifting type holding self-locking assembly (3) are combined into a closed box body to wrap the printer, and the push plate (421) can be freely rotated at this time, and the front end of the lifting type holding self-locking assembly (3) can be opened by rotating the push plate (421) to unlock the locking assembly (43).
