The main function of the hydraulic valve block is to provide installation locations for various hydraulic valves, realize the connection and distribution of oil circuits, and also facilitate the installation, debugging and maintenance of the system. However, the hydraulic valve blocks in space are different from traditional hydraulic valve blocks. The 3D printed hydraulic manifold is no longer a regular rectangular structure, but a group of "pipes" with irregular shapes. This design can reduce weight and cost by reducing the number of parts and simplifying the process chain.

[0009] Furthermore, four L-shaped lock buckles are rotatably connected to both sides of the exterior of the outer shell, and the outer sides of the L-shaped lock buckles are fitted with the outer sides of the side covers.

[0010] Furthermore, the outer side of the connecting piece is slidably connected to the inner side of the slot, and the outer side of the clamping block is clamped in the inner side of the clamping hole.

[0011] Furthermore, one end of the push rod is in contact with the outer side of the block.

[0012] Furthermore, the exterior of the valve block body is engaged with the interior of the hole.

[0013] The utility model has the following beneficial effects:
