Provided is a clamping and lubricating device for a lobe-shaped chain. An oil-resistant piece on the left side and an oil-resistant piece on the right side are of a symmetrical structure and matched with each other by means of a key groove. A connecting shaft penetrates through an upper part and a lower part of an occlusion hook. A pressing rod is connected with one end of the connecting shaft. A protrusion is arranged on the pressing rod and in contact with the surface of a lower part of the occlusion hook. By applying pressure upon the pressing rod, the connecting shaft, the upper part and the lower part of the occlusion hook are driven to occlude with each other so that the chain is clamped tightly. When the chain is needed to be lubricated for installation, a lobe-shaped shell is pressed and at that time pressure is applied to the pressing rod and free ends at the upper part and the lower part of the occlusion hook are occluded with each other for clamping the chain. Meantime, a lubrication oil liquid bag is extruded and lubrication oil in the lubrication oil liquid bag enters an oil feeding port of the occlusion hook and is directly drained away from oil discharging ports along a lubrication oil channel. Through the two oil discharging ports at the upper part and the lower part of the occlusion hook, the top and the bottom of the chain can be lubricated at the same time.
