[0002] Excavators are widely used in the field of engineering construction. There are many grippers on the market for grabbing materials such as wood, stone, scrap iron, and scrap steel. In actual use, common grippers usually grab inward on both sides, with poor gripping performance. They cannot grab materials such as sand, gravel, and soil. Block materials are easy to drop and the amount of material handled each time is small, which leads to low work efficiency. There is usually no pressure-maintaining device, and there are serious safety hazards in the event of oil pipe rupture. The existing products have low structural strength, severe deformation during grabbing, and cannot grab at multiple angles, and can only grab vertically up and down. Therefore, it is crucial to develop a lotus gripper that improves the above problems. Utility Model Content

[0003] The utility model aims at the deficiencies in the prior art and provides a lotus grip.

[0004] The technical solution of the utility model to solve the above technical problems is as follows:

The five lotus gripper petals are closed into a bud shape. A diverter is provided at the center of the petal connector. An oil cylinder assembly connected to the diverter is installed on the lotus gripper petal. A safety valve group is provided on the oil cylinder assembly. A wear-resistant bending plate extending outward along the inner side of the lotus gripper petal is provided on the inner side of the lotus gripper petal.

[0006] Furthermore, a closing limit block is provided at the connecting end of the lotus petal and the orange petal connector.

[0007] Furthermore, the orange petal connector includes an ear plate for hinged connection of the lotus petal, and a cylinder connection hole and an orange petal connection hole are provided on the ear plate, and the cylinder connection hole is located at the outer end above the orange petal connection hole.

[0008] Furthermore, the orange segment connector is provided with an inspection cover, which is located between adjacent ear plates and is designed with an opening.

[0009] Furthermore, an upper fixing plate is provided at the upper end of the orange petal connector and a lower fixing plate is provided at the lower end. The upper fixing plate is located above the ear plate and is used to shield the cylinder connection end, and the lower fixing plate is located below the ear plate and is used to block the lotus petal connection end.

[0010] Furthermore, the lotus petal is provided with a cylinder hinge hole hinged to the cylinder assembly and a petal hinge hole hinged to the orange petal connecting hole.

[0011] Furthermore, a protective bending plate is provided at the upper end of the lotus petal, and a main board reinforcement bending plate is provided at the lower end.

[0012] Furthermore, when the five lotus petals are closed, the adjacent wear-resistant bending plates are joined together within a range from the front end to the half of the root.

[0013] Furthermore, the wear-resistant bending plate is provided with reinforcing ribs.

[0014] Compared with the prior art, the beneficial effects of the utility model are: the structure of the present application is simple and easy to operate.
