[0028] Specifically, when the first connecting handle 31 and the second connecting handle 32 are in the working mode, the extending direction of the first connecting handle 31 and the extending direction of the second connecting handle 32 are on a straight line.

[0029] By setting a rotatable second connecting handle 32, the first connecting handle 31 and the second connecting handle 32 can be switched between different connection modes. When the first connecting handle 31 and the second connecting handle 32 are in the protection mode, a accommodating space 4 is formed between the first connecting handle 31 and the second connecting handle 32. The accommodating space 4 can be used to accommodate the hands of construction workers, and the second connecting handle 32 can be used to protect the back of the hands. When using the multifunctional mining tool in this embodiment to remove the U-shaped pin 10, the first pin lifting part 2 is inserted into the cavity of the U-shaped pin 10 so that the first pin lifting part 2 abuts against the U-shaped pin 10. By utilizing the principle of leverage, the U-shaped pin 10 can be removed more labor-savingly, and the work of opening, pulling out and installing the pin can be realized by a single person. It is convenient, fast and easy to carry, and at the same time, it realizes the protection function for human hands, avoids the situation where construction workers are injured due to collision due to excessive force during operation, and solves the technical problem of difficulty in disassembling the U-shaped pin in the related technology.

[0030] Specifically, when installing the U-shaped pin 10 , the hammer 11 may be used to strike the U-shaped pin 10 , so that the U-shaped pin 10 enters the installation hole more quickly.
