Latest Patents

One of Jian Gang Qu's latest inventions is an angle grinder. This angle grinder comprises a motor and an output member to which a grinding disc is attachable. The output member defines an output axis, and a drive shaft is configured to transfer torque from the motor to the output member. A braking disc is coupled to the drive shaft, and a braking pad is moveable in a direction transverse to the drive axis between a first braking pad position and a second braking pad position, in which the braking pad is not in contact with the braking disc. A biasing member biases the braking pad toward the first braking pad position, and a trigger is pivotable about a trigger axis between a first trigger position and a second trigger position. In response to the trigger being pivoted from the first to the second trigger position, the braking pad is moved from the first to the second braking pad position.

Another significant invention by Qu is a powered threaded rod cutter. This device is configured to perform a cutting operation on a threaded rod and includes a first cutting die and a second cutting die. At least the first cutting die includes a recess in which a first portion of the threaded rod is at least partly receivable, along with an electric motor and a planetary transmission positioned downstream of the electric motor. The powered threaded rod cutter additionally includes a drivetrain for converting a rotational output of the planetary transmission to a pivoting movement of the second cutting die, and a guide against which a second portion of the threaded rod may contact to support the threaded rod to be perpendicular relative to the second cutting die prior to the cutting operation.
