[0009] Preferably, a placement groove is formed in the bottom surface of the lower connecting rod cover. A sliding plate is slidably arranged inside the placement groove. Limiting grooves are respectively formed on both sides inside the placement groove. Limiting strips are respectively fixed on both sides of the sliding plate. The limiting grooves and the limiting strips are slidably arranged. A positioning plate is fixed to the bottom surface of the sliding plate. A grasping opening is formed on one side of the positioning plate.

[0010] Preferably, threaded grooves are respectively formed at both ends of the limiting strip. Blocking plates are respectively detachably arranged at both ends of the limiting strip. Extrusion bolts are arranged at both ends of the limiting strip. One end of the extrusion bolt passes through the blocking plate and is threadedly connected to the threaded groove.

[0011] Compared with the prior art, a connecting rod lubrication structure adopting the above technical scheme has the following beneficial effects:

[0012] First, the staff will first disassemble the lower connecting rod cover and the upper connecting rod cover, and then place the connecting rod in the fixing groove formed on the top surface of the lower connecting rod cover and contact the inner wall surface of the bearing bush. Then, the staff adds thick oil into the oil groove through the upper oil inlet hole and the lower oil inlet hole for lubrication, so that the thick oil for lubrication can be supplemented at any time, increasing the lubrication effect on the connecting rod.

[0013] Second, after placing the connecting rod only inside the fixing groove, the staff will buckle the upper connecting rod cover on the top surface of the lower connecting rod cover, and then pass the installation bolt through the positioning hole and screw it into the installation groove, so that the lower connecting rod cover and the upper connecting rod cover can be fixed together, and the connecting rod can be wrapped inside the bearing bush, making the surface of the connecting rod fully contact with the thick oil.

[0014] Third, when the staff lubricates the connecting rod, it may be necessary to slide horizontally on the connecting rod. In order to prevent the thick oil for lubrication from contaminating the staff's arm, the staff can hold the palm on the positioning plate, which can avoid the staff's palm directly contacting the lower connecting rod cover and the upper connecting rod cover, prevent the thick oil for lubrication from contacting the staff's palm and causing pollution, and increase the safety of the staff during lubrication.
