Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

A control box structure 5 is connected to the side of the column. In this embodiment, the lifting slide sleeve is a prior art structure. The lifting slide sleeve is connected to a lifting cylinder on the column, mainly used to drive the entire tire shovel structure to lift and lower. The connection between the two is a conventional method, so it is not described in detail. In actual application, pulley assemblies 6 are provided at the top and bottom of the lifting slide sleeve to ensure smooth lifting and lowering.

[0055] The tire-removing structure 4 includes a square kit 41, a square hollow sliding arm 42, a tire-removing arm rotating structure 43, a fine-tuning control cylinder 44, a locking buckle structure 45, and a positioning pin structure 46. The length of the square hollow sliding arm matches the length of the square kit, and the square hollow sliding arm can extend and retract within the square kit under external force. During installation, the square kit is fixed to the mounting plate. The square hollow sliding arm is slidably disposed within the square kit. The fine-tuning control cylinder is fixed to the end of the square kit, and the piston shaft of the fine-tuning control cylinder passes through the square hollow sliding arm and connects to the end of the tire-removing arm rotating structure. The locking buckle structure is fixed to the top of the square kit, and the locking buckle structure can press against the top surface of the square hollow sliding arm to position the square hollow sliding arm. The positioning pin structure is disposed on the tire-removing arm rotating structure and rotates and positions the tire-removing arm rotating structure. The locking buckle structure is mainly used to lock and position the square hollow sliding arm when it extends and retracts within the square kit, ensuring its extension and retraction position.

[0056] Meanwhile, in practical application, the tire-removing arm rotating structure 43 includes a square telescopic rod 431, an L-shaped rotating arm 432, and a tire-pressing plate 433. The outer side of the square telescopic rod is integrally formed with a circular column 434. One end of the L-shaped rotating arm has a circular hole that mates with the circular column. A positioning pin structure is fixed to the side wall of the L-shaped rotating arm, and the positioning pin structure can extend into the circular hole and abut against the circular column for positioning. The tire-pressing plate is fixed to the other end of the L-shaped rotating arm.

Under the action of the spring, the inner end of the positioning pin rod passes through the L-shaped rotating arm and presses against the positioning pin hole, thus limiting the L-shaped rotating arm. Under the action of external force, the positioning pin rod disengages from the positioning pin hole, at which point the L-shaped rotating arm can rotate on the cylindrical surface. The positioning pin is mainly used for rotational positioning to ensure the stability and reliability of the rotational position.

[0058] The locking buckle structure 45 includes a buckle base 451, a locking buckle 452, a torsion spring 453, and a handle 454.

The corresponding hand-push valve can be operated with one hand to achieve the lifting and translating of the tire-removing arm structure, and the fine-tuning control cylinder can be activated via the control plate to achieve fine-tuning of the tire-removing arm rotating structure.

[0060] In practical applications, a handle assembly 7 is fixed to the side of the four-way kit. The handle assembly includes a control handle 71, a handle valve stem 72, and a quick-connect coupling 73. The control handle is fixed to the side of the four-way kit, and the quick-connect coupling is fixed to the side of the control handle. The handle valve stem is fixed to the control handle and communicates with the quick-connect coupling. The quick-connect coupling is connected to the fine-tuning control cylinder.

With the help of the control box structure, it is not only easy to operate, but can also directly drive the square hollow sliding arm to move within the square kit. Moreover, the tire-removing arm rotating structure can be slightly moved by the fine-tuning control cylinder, which improves the convenience, stability and reliability of tire removal. At the same time, it only requires one control box structure to realize control, which reduces the setting of control structure and improves the convenience and effectiveness of control operation. It has strong applicability and good practicality.
