With the development of society, the oil cylinder lifting bracket is widely used in industry, such as excavators, lifting frames and other devices.

[0003] A kind of oil cylinder lifting bracket disclosed in the Chinese utility model patent application disclosure specification CN217233981U is provided with a reinforcement device. When the stabilizing rod rises to a suitable position, the block one and the block two are rotated, and the pulling block is pulled at the same time. The connecting block slides successively under force, and the fixing spring is deformed and expanded after being subjected to force at the same time. When the block one and the block two are connected with the surface sleeve of the stabilizing rod, the pulling block is released, and the fixing spring rebounds and pulls the connecting block after losing the restraint at the same time. The card block is inserted into the inner wall of the block one under force at the same time, and then the insertion rod is pushed to be inserted into the inner wall of the card block. By providing a reinforcement device, it is convenient to perform auxiliary positioning operation on the equipment when the equipment body is supported, effectively absorb the force on the equipment body, reduce the failure rate of the equipment body, reduce the safety hazards of the equipment in use, reduce the economic loss of the user, and facilitate the normal use of the equipment. However, the existing oil cylinder lifting bracket structure is relatively simple, the position between the bracket and the oil cylinder is fixed, it is not convenient to replace and repair the oil cylinder, and the overall practicality is low.
