Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The utility model discloses an embodiment, as shown in fig. 1 and 2, including bent axle main part 1, bent axle main part 1's middle section is provided with connecting rod neck 2, and connecting rod neck 2's both sides are provided with crank arm 3 respectively, and crank arm 3 below is provided with first balancing piece 4, and first balancing piece 4 is connected with bent axle main part 1, and first balancing piece 4's below is connected with second balancing piece 5, and main oil duct 6 has been seted up to one side of crank arm 3.
The bottom of the first balance block 4 is at least provided with a threaded connecting hole and two pin holes, the pin holes are distributed on two sides of the threaded connecting hole and used for positioning, and the threaded connecting hole is used for fixing.
As shown in fig. 3, the second weight 5 is provided with a threaded connection hole and a pin hole corresponding to the bottom dimension position of the first weight 4, the second weight 5 is semicircular, the circular arc bottom of the second weight 5 is provided with a rectangular groove, a bolt is arranged in the rectangular groove and fixedly connected with the first weight 4, when the second weight 5 is installed, the pin is placed in the pin hole of the second weight 5, and the second weight 5 is locked and fixed at the bottom of the first weight 4 through the bolt in the rectangular groove at the bottom of the second weight 5.
