[0025] An aluminum template capable of preventing loosening comprises an aluminum template body 1 and a pin 9, wherein connecting pin holes 2 are provided on the outer sides of the aluminum template body 1, bosses 4 are installed on the inner sides of the aluminum template body 1, fixing holes 3 are provided on the inner sides of the bosses 4, reinforcement grooves 5 are provided on the top and bottom sides of the fixing holes 3, reinforcement bolts 6 are arranged in the reinforcement grooves 5, a connecting groove 7 is provided on the right side of the aluminum template body 1, a connecting block 8 is provided on the left side of the aluminum template body 1, a pin cap 10 is installed on the rear end of the pin 9, a reinforcement block 11 is installed on the front side of the pin cap 10, and a fixing through groove 12 is provided at the center of the reinforcement block 11;

[0026] Specifically, the outer side of the pin 9 corresponds to the inner thread structure of the connecting pin hole 2, and the pin 9 is rotatably connected to the inside of the connecting pin hole 2, the inner diameter of the fixing hole 3 is slightly larger than the inner diameter of the connecting pin hole 2, and the depth and structure of the fixing hole 3 correspond to the reinforcement block 11;

[0027] In this embodiment, the pin 9 is conveniently connected to the connecting pin hole 2 for fixing, and the fixing hole 3 is designed so that the reinforcement block 11 can be stuck inside the fixing hole 3 to form a limiting space, thereby increasing the stability of the connection.
