[0002] The crankshaft is the most important part of the engine. It bears the force from the connecting rod and converts it into torque, which is output through the crankshaft and drives other accessories on the engine to work.

[0003] After searching, the patent announcement number CN209717364U discloses a counterweight device for a crankshaft grinder, which relates to the technical field of grinders, and includes a grinder body, the opposite surfaces of the inner wall of the grinder body are provided with the same crankshaft, the left and right sides of the grinder body are provided with handwheels, the front of the handwheel is provided with a first groove, the lower surface of the inner wall of the first groove is clamped with a fixing device, and the top of the fixing device overlaps with the lower surface of the first counterweight. The counterweight device for a crankshaft grinder is provided with a second threaded cap, a second threaded rod, a pressure block, a push plate, a second counterweight and a handwheel, so that the push plate drives the pressure block to squeeze the second counterweight. After the staff turns the handle and releases it, the gravity of the handle itself will not drive the handwheel to rotate, so that the handwheel effectively maintains a balanced state, which is convenient for the staff to clamp the workpiece, so that the workpiece is not easy to shake when the grinder body is processing the workpiece, thereby improving the accuracy of the workpiece processing.

[0004] The CN209717364U in the prior art facilitates the staff to clamp the workpiece during use, so that the workpiece is not easy to shake when the grinder body is processing the workpiece, thereby improving the accuracy of workpiece processing. However, in actual use, the crankshaft is large and the staff cannot directly load the crankshaft. Therefore, it needs to be improved when using the grinder for processing. Utility Model Content
