The invention discloses a novel arm rest bracket device (1). The novel arm rest bracket device (1) comprises a U-shaped bracket head (11), a straight bracket handle (12) and a slant bracket handle (13). The straight bracket handle (12) is perpendicularly welded to the lower portion of the U-shaped bracket head (11). A 120-degree included angle is formed between the straight bracket handle (12) and the slant bracket handle (13), and the straight bracket handle (12) and the slant bracket handle (13) are welded in a fastened mode. A main arm (2) is supported by the U-shaped bracket head (11). A plurality of sliding blocks (110) made of polyester ethylene are installed inside the U-shaped bracket head (11). The novel arm rest bracket device is installed on a small arm in the middle of equipment in a welded mode and used for supporting the longest main arm at the upper portion; in this way, when the equipment is in the storage state, the pressure of the main arm and a platform fence is not concentrated on a stretchable oil cylinder connected with a rotating tower, at least one third of the pressure borne by the stretchable oil cylinder is reduced, and meanwhile the service life of the stretchable oil cylinder is prolonged.
