[0026] like Figures 1-6 As shown, the anchor drilling rig multiplier fixing frame provided in this embodiment includes an anchor drilling rig 1 and a torque multiplier 2. A drilling rig guard ring 3 is fixedly connected to the outside of the anchor drilling rig 1. Handles 4 are connected to both sides of the torque multiplier 2. Two symmetrically distributed U-shaped frames 5 are rotatably mounted on the drilling rig guard ring 3. A U-shaped clip 6 is connected to the middle of the U-shaped frame 5. A slot 7 for cooperating with the U-shaped clip 6 is opened on the top of the handle 4. Through the arrangement of the U-shaped frame 5, handle 4, U-shaped clip 6 and slot 7, the anchor drilling rig 1 and the torque multiplier 2 are connected to each other. Flipping the U-shaped frame 5 allows the U-shaped clip 6 to be inserted into the slot 7, which can play a fixing role. The installation and removal are convenient and quick, without manual operation, which is safer and more stable, and can prevent it from falling off due to vibration. The arrangement of two symmetrically distributed U-shaped frames 5 improves the fixing effect.
