Specially-made connecting piece for preventing die expansion at aluminum-wood combined part

The utility model relates to the technical field of connecting pieces, and discloses a special connecting piece for preventing the die expansion of an aluminum-wood combined part, which comprises a main body mechanism, a supporting mechanism and a clamping mechanism, and is characterized in that the supporting mechanism is positioned below the main body mechanism, and the clamping mechanism is positioned above the main body mechanism; the clamping mechanism comprises a limiting transverse plate, a right limiting plate, a left limiting plate, a limiting vertical plate and a transverse limiting plate. According to the special connecting piece for preventing the aluminum-wood joint from expanding, longitudinal plates placed in the connecting piece can be limited through the arranged left limiting plate and the right limiting plate, the limited plates can be reinforced through the arranged first fixing pins, and then the plates are collected through the first nuts, so that the plates are not prone to expanding an
