For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] The utility model will be further described below in conjunction with the accompanying drawings.

[0019] Please refer to Figure 1-Figure 4 The utility model is a portable tool box for crane maintenance, comprising: a base 1, a shell 2 is connected to the upper end of the base 1, a storage drawer 3 is movably connected to the inner side of the shell 2, a limiting opening 4 is arranged at one end of the shell 2, a limiting block 5 is arranged at the outer side of one end of the storage drawer 3 corresponding to the limiting opening 4, a positioning hole 6 is opened at the corner of the upper end of the shell 2, and a first positioning rod 7 is arranged at the corner of the bottom end of the shell 2.

[0020] Combination Figure 3 and Figure 4 As shown, the positioning hole 6 is opposite to the first positioning rod 7, and the inner circle diameter of the positioning hole 6 is the same as the outer circle diameter of the first positioning rod 7, so as to facilitate the docking of two upper and lower adjacent shells 2. There are several shells 2, and a handle 8 is arranged on the outer side of the storage drawer 3 near the limit opening 4. The limit opening 4 cooperates with the limit block 5 to limit the maximum extent to which the storage drawer 3 can be pulled out. An elastic plug rod 9 is arranged inside the storage drawer 3 on one side above the handle 8, and a socket is arranged at the bottom end of the shell 2 facing the end of the elastic plug rod 9. The top end of the elastic plug rod 9 extends into the socket, and the storage drawer 3 can be limited by the elastic plug rod 9, so that when the storage drawer 3 is closed, the storage drawer 3 can be prevented from sliding out at will.
