[0032] A group of equidistant slots 12 are provided on the upper surface of the inner seat 4, a group of equidistant weight-reducing slots 11 are provided on the side of the inner seat 4, and two placement slots 10 are provided on the surface of the connecting seat 2 facing the tire removal assembly 14. When the connecting seat 2 is against the main frame 1, the two placement slots 10 are respectively movably engaged with the two fixing bars 5, and magnets are fixedly installed at the ends of the two blocking rods 8. The magnets on the two blocking rods 8 have opposite magnetic properties. The inner seat 4 is movably sleeved in the hollow slot 9, and the connection between the connecting seat 2 and the main frame can be released by turning the nut on the stud 7. 1, at this time, the main frame 1 can be pulled to separate it from the connecting seat 2 to achieve the effect of telescopic tire unloading arm. The telescopic length is determined by the card slot 12 where the blocking rod 8 is stuck in the corresponding position. A variety of telescopic lengths can be selected, which improves the applicability of telescopic. After the blocking rod 8 is stuck in the card slot 12, the magnets at the ends of the two blocking rods 8 attract each other, so that the blocking rod 8 can be stable in the card slot 12 and is not easy to be separated from the card slot 12 due to the vibration of the equipment, so that the length of the tire unloading arm after telescopic remains stable. The operator starts the pneumatic system and drives the cylinder 15 to start working. The piston rod of the cylinder 15 extends out, pushing the movable plate 16 connected to it to move downward, and the movable plate 16 steadily descends until it reaches the predetermined position. At this time, the lower end position of the movable plate 16 is accurately embedded in the corresponding card slot 12 to form a stable locking state.

The telescopic length is determined by the blocking rod 8 stuck in the corresponding position of the slot 12. A variety of telescopic lengths can be selected, which improves the applicability of telescopic. After the blocking rod 8 is stuck in the slot 12, the magnets at the ends of the two blocking rods 8 attract each other, so that the blocking rod 8 can be stabilized in the slot 12 and is not easily separated from the slot 12 due to the vibration of the equipment, so that the length of the tire unloading arm after telescopic remains stable. The operator starts the pneumatic system and drives the cylinder 15 to start working. The piston rod of the cylinder 15 extends out, pushing the movable plate 16 connected thereto to move downward, and the movable plate 16 descends steadily until it reaches the predetermined position. At this time, the lower end of the movable plate 16 is accurately embedded in the corresponding slot 12 to form a stable locking state. This process realizes the precise fixation of the length of the tire removal arm, laying the foundation for the subsequent tire removal work. Through this mechanical linkage design, both the convenience of operation and the stability and safety of the tire removal process are guaranteed.
