Connecting rod

The connecting rod comprises a connecting rod body, an oil box for containing lubricating oil is welded to the outer side of the connecting rod body, a concave hole for enabling the lubricating oil in the oil box to flow into an oil cavity in the connecting rod body is formed in the surface of the connecting rod body, and a ball for controlling the flow speed of the lubricating oil in the oil box is placed on the inner side of the concave hole. A through hole through which lubricating oil in the oil cavity flows out is formed in the inner side of the connecting rod main body; through the arrangement of the ball, the concave hole, the through hole, the oil cavity and the oil box, the problems that when an existing connecting rod is used, lubricating oil is inconvenient to add to the connecting position of the connecting rod body and an engine, and the connecting rod body cannot operate flexibly are solved. 本实用新型公开了一种连杆，包括括连杆主体，所述连杆主体外侧焊接有呈放润滑油的油盒，所述连杆主体表面开设有使油盒内的润滑油流入连杆主体内部油腔的凹孔，所述凹孔内侧放置有控制油盒内润滑油流速的滚珠，所述连杆主体内侧
