[0020] The following will further describe the present application in detail Figures 2-4 with reference to the accompanying drawings.

[0021] The embodiment of the present application discloses a riveting device for installing a sector gear of a seat adjuster rocker arm. Refer to Figures 2-4 , which includes a machine base 1, a riveting machine 2 is installed on the machine base 1, a material clamping mechanism 3 is arranged at a position corresponding to the riveting machine 2 on the machine base 1. The material clamping mechanism 3 includes a base 31, a pressing cylinder 32, a pressing block 33, a tensioning cylinder 34 and a pneumatic three-jaw chuck 38. The base 31 is fixed on the machine base 1. A placement groove 311 for placing the rocker arm is arranged on the base 31. A riveting platform 312 is also arranged on the base 31. A groove 313 is opened in the riveting platform 312. The tensioning cylinder 34 is fixed in the groove 313. The pneumatic three-jaw chuck 38 is movably arranged in the groove 313, and the pneumatic three-jaw chuck 38 is fixed at the output end of the tensioning cylinder 34. A pipe-passing groove 314 is opened beside the groove 313 on the base 31. A pull rod 35 is fixed on the chuck of the pneumatic three-jaw chuck 38.
