Patent ID: 7156187

Claim:
A method to provide rotational work on a securing element located within a small space, said method comprising: a. providing a housing having a main body and a reaching arm, the main body and reaching arm configured along a longitudinal, transverse and vertical axis system, b. providing in the main body a power source, a drive motor, a drive shaft, and a drive shaft center line, c. providing in the reaching arm a first transversely aligned drive shaft and a second transversely aligned drive shaft, a front section, a rear section, and a longitudinally aligned transmission, d. positioning the first transversely aligned drive shaft at the longitudinally rearward end of the rear section, e. connecting the first transversely aligned drive shaft to the drive shaft, f. positioning the longitudinally aligned transmission transversely off-center from the drive shaft center line, g. connecting the first transversely aligned drive shaft to the longitudinally aligned transmission, h. positioning the second transversely aligned drive shaft longitudinally forward of said first transversely aligned drive shaft, i. connecting said longitudinally aligned transmission to said second transversely aligned drive shaft, j. connecting said front section to said second transversely aligned drive shaft, k. allowing said front section to rotate freely about said second transversely aligned drive shaft, I. fixing said front section in a chosen rotational degree of freedom to work within said small space, m. securing a spindle in said front section along a radial axis from said second transversely aligned drive shaft, n. allowing said spindle to rotate about said radial axis, o. connecting said second transversely aligned drive shaft to said spindle, p. actuating the power source and driving the drive motor to drive the drive shaft, said drive shaft providing rotational work to said first transversely aligned drive shaft, said first transversely aligned drive shaft providing rotational work to said longitudinally aligned transmission, said longitudinally aligned transmission providing rotational work to said second transversely aligned drive shaft, said second transversely aligned drive shaft providing rotational work to said spindle, said spindle providing rotation work to said securing element.
