The electromagnet is installed on the main board and used to adsorb the valve body; the clamping assembly is used to clamp hydraulic components and includes a first clamp and a second clamp installed at both ends of the main board respectively. The utility model can solve the technical problems of inconvenient handling, high cost and poor compatibility in the prior art. When moving the hydraulic valve group up and down, there is no need for manual handling, which reduces the operating intensity of the operator and ensures the product cleanliness of the hydraulic valve group. In addition, two grabbing structures, the electromagnet and the clamp, are adopted, which greatly improves the applicability of the product structure, and there is no need to replace the clamp when clamping multiple parts.
