Introduction

Jian Wei Li is a notable inventor based in Dongguan, China. He has made significant contributions to the field of power tools and expansion devices, holding a total of five patents. His innovative designs reflect a deep understanding of mechanical engineering and user needs.

Latest Patents

One of Jian Wei Li's latest patents is a rotary power tool that includes a transmission housing bushing. This rotary power tool comprises a drive mechanism featuring an electric motor and a transmission. It is designed with a housing that encloses a portion of the drive mechanism, a spindle that rotates in response to torque, and a first ratchet coupled for co-rotation with the spindle. The second ratchet is rotationally fixed to the housing, while a sleeve bushing is supported by the housing. A bearing rotatably supports the spindle, allowing the outer race of the bearing to move along the sleeve bushing during the reciprocation of the spindle when the first and second ratchets are engaged.

Another significant invention is an expansion tool that includes a housing and a collar rotatably coupled to it. This tool features a plurality of jaws that are coupled for co-rotation with the collar. A mandrel is movable relative to the housing between a retracted and an extended position to expand the jaws. The drive mechanism includes a rotatable cam that moves the mandrel, and an indexing gear is configured to incrementally receive torque from the drive mechanism. This allows for continuous rotation of the drive mechanism to incrementally rotate the indexing gear, enhancing the tool's functionality.
