When the mobile bracket 4 needs to be parked, it is only necessary to rotate the screw relative to the threaded sleeve so that the support plate moves downward and is supported on the ground.

[0030] The flexible conveyor frame 5 comprises two groups of long round strips 5.1 hinged end to end, the long round strips 5.1 at the front end are respectively hinged to the front end of the connecting strips 2.3.

[0034] In summary, when the conveying distance needs to be increased, first disengage the bolt in the through hole 5.2.1 from the positioning screw hole 6.5, then release the parking function of the parking mechanism 4.4, and push the mobile bracket 4 backward under the support of the walking wheel 4.3, thereby pulling the side beam 2.1, so that the side beam 2.1 slides backward along the inner wall of the support beam 1.2. The side beam 2.1 also pulls the two groups of oblong slats 5.1, so that the flexible conveying frame 5 is dragged under the guidance of the cage roller 7.2. When the required conveying distance is reached, the bolts in the through hole 5.2.1 are re-connected with the corresponding positioning screw hole 6.5, and then the mobile bracket 4 is parked using the parking mechanism 4.4. In order to facilitate effective support for the flexible conveying frame 5, support wheels are rotatably mounted on the outer ends of the hinge shafts of the long circular slats 5.1. Under the pulling action of the side beams 2.1, the support wheels can just enter the groove structure between the upper and lower slide grooves 1.3, and the support wheels provide effective support for the flexible conveying frame 5.
