Because the opening of the piston hole and the air storage cavity is designed on the outer side wall of the X axis of the side wall, in order to reasonably utilize the space, the size of the side wall in the direction of the Y axis or the Z axis is compressed, the shape of the opening of the air storage cavity can be designed to be rectangular, and the side of the rectangular side close to the piston hole is arc-shaped.

Preferably, the side wall is provided with ribs on both sides in the Z-axis direction. The design can obviously improve the strength of the side wall in the X direction, so that the thickness dimension of the side wall can be reasonably compressed.

Preferably, a machine leg bolt hole is formed in the lower portion of the machine leg and extends upwards along the Y-axis direction, and the machine leg bolt hole is a blind hole. The machine foot bolt hole is used for realizing fixing the machine foot, and the axial design of the machine foot bolt hole is in the Y-axis direction, so that the space in the X-axis Z-axis direction can be prevented from being occupied.

Preferably, the side of the machine leg is provided with a chip removal hole, the inner side of the chip removal hole is connected with the root part of the bolt hole of the machine leg, and the outer part of the chip removal hole is opened on the outer side wall of the machine leg. The chip removal holes are used to remove workpiece chips from the bolt holes of the machine foot during machining and assembly.

To sum up, the beneficial effects of the utility model are that: the size is small, the device can be well adapted to mobile environments such as vehicle-mounted environments and the like, and the material cost is also superior.
