For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0027] As Figures 1 to 3 shown, the present utility model provides a safety clamp for lifting a material bucket, including: a first claw 1, a second claw 2, a first connecting member, a second connecting member, and a locking member; the first claw 1 is used to connect with the fixed shaft 12 of the hoist, and the second claw 2 is used to connect with the fitting 13 of the material bucket; the first claw 1 is connected with the first connecting member, and the second claw 2 is connected with the second connecting member, and the first claw 1 and the second claw 2 are arranged oppositely; the first connecting member and the second connecting member are movably connected so as to be able to approach or move away from each other, thereby adjusting the position of the first claw 1 relative to the second claw 2; the locking member is connected between the first connecting member and the second connecting member to lock the first connecting member and the second connecting member.

[0028] In this embodiment, when the hoist is used to lift the bucket, the fixed shaft 12 is inserted into the lifting hole. The first claw 1 is connected to the fixed shaft 12 of the hoist, and the second claw 2 is connected to the fitting 13 of the bucket. Then, the relative positions of the first connecting member and the second connecting member are adjusted and locked by the locking member, so that the relative positions of the first connecting member and the second connecting member are fixed. In this way, the first claw 1 can lock the fixed shaft 12, and the second claw 2 can lock the fitting 13. Under the action of the first claw 1 and the second claw 2, the fixed shaft 12 can be pressed against the lifting hole, locking the fixed shaft 12 relative to the fitting 13, and further locking the fixed shaft 12 to the bucket, thus preventing the fixed shaft 12 from moving relative to the lifting hole and falling off from the lifting hole, and further preventing the bucket from slipping off the hoist, avoiding damage to the bucket caused by dropping and material leakage, and improving the safety of bucket lifting. After the bucket is transported to the designated position, the first connecting member and the second connecting member are released by the locking member, so that the first connecting member and the second connecting member can move relative to each other, so that the first claw 1 can release the fixed shaft 12, and the second claw 2 can release the fitting 13, so that the bucket lifting installation card can be removed.
