Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

As shown in fig. 1-4, an eccentric rotating shaft for a gear box is provided, which comprises a first rotating shaft 1, a connecting rod 2 is fixedly installed at one end of the first rotating shaft 1, a second rotating shaft 4 is fixedly sleeved at the other end of the connecting rod 2, a lower buckle 5 is fixedly installed at the bottom of the first rotating shaft 1 close to one end of the second rotating shaft 4, an upper clamping plate 6 and a lower clamping plate 8 are clamped in the lower buckle 5, an automatic elastic buckle 7 is movably sleeved at the top of the bottom side of the upper clamping plate 6, and a fixing bolt 9 is sleeved at the top thread of the lower clamping plate 8.

As shown in fig. 2, locating hole 3 has been seted up to the one end that second pivot 4 is close to first pivot 1, connecting rod 2 has been cup jointed to the activity in locating hole 3, and the degree of depth value of locating hole 3 is greater than the length value of connecting rod 2, locating hole 3 is seted up through the one end at second pivot 4, make connecting rod 2 can cup joint wherein, thereby guaranteed to be connected between first pivot 1 and the second pivot 4, and set up the degree of depth value of locating hole 3 into the length value that is greater than connecting rod 2, thereby make between first pivot 1 and the second pivot 4 can laminate inseparabler.
