Three fixing cylinders 5 are provided, and the fixing cylinders 5 are evenly distributed around the fixing ring 2. The connecting clamp 53 is a hydraulic telescopic structure with the hydraulic rod 51 through the telescopic long rod, and the three connecting clamps 53 fix the engine rocker arm at multiple points. The fixing cylinder 5, the hydraulic rod 51, the infusion pipeline 52, the connecting clamp 53, the roller 54, the friction ring 55 and the connecting bolt 56 constitute a hydraulic clamping tool, through which the hydraulic clamping tool is clamped along the four sides of the fixing ring 2. The rocker arms are evenly distributed around the engine, and when the engine rocker arm is placed in the rocker arm placement plate 6, the multiple hydraulic clamping tools thereof perform multi-point positioning and clamping of the engine rocker arm, thereby meeting the requirements for multi-point positioning of the engine rocker arm and reducing the possibility of scratches on the engine rocker arm and the clamping tools during the drilling process. At the same time, the hydraulic clamping tool adopts a friction ring 55 as a buffer, thereby reducing the possibility of hard damage to the engine rocker arm caused by the hydraulic clamping tool. At the same time, since the friction ring 55 is a consumable part, it is connected to the connecting chuck 53 by a connecting bolt 56, thereby meeting the user's requirement for quick replacement of the friction ring 55, bringing convenience to the user and facilitating the use of the user.

[0025] Embodiment 3

[0026] On the basis of the second embodiment, a rocker arm placement plate 6 for placing the rocker arm is set at the center of the chassis 1, and a plurality of filter holes 61 for lubricating oil to flow out are opened on the surface of the rocker arm placement plate 6. The rocker arm placement plate 6 is used as a placement component for carrying the rocker arm, and is connected to the chassis 1 in a fixed integrated connection manner. The connection strength at the connection is high and the structure is stable. In addition, a plurality of filter holes 61 are opened on the surface of the rocker arm placement plate 6 to meet the needs of users to introduce drilling debris and lubricating liquid from the filter holes 61 into the collection device, which brings convenience to the user. The inner wall of the pipe clamp 4 is sleeved with a lubricating liquid inlet pipe 41, and the lubricating liquid inlet pipe 41 is close to the engine.
