1. A multi-angle all-purpose ratchet screwdriver comprising:

  • a screwdriver chuck having one end for holding different size fastener loosening tools and having another end formed as a U-shaped hinged section having two vertical arms formed with serrations which constitute a multi-angular ratchet wheel;

    a handle having a hinge tab, a threaded section and grip section having a tubular space therein;

    a positioner plate for screwing, securing and movement on the threaded section;

    a ratchet-angle locking plate having a slot for inserting the hinge tab of the handle, and having two rows of toothed ridges which enmesh with said serrations;

    a first connecting means for pivotally connecting said screwdriver chuck to said handle;

    an accessories holder installed into the tubular space inside the handle for holding different size screw unfastening tools;

    a seat guide secured onto an upper end of the grip section of the handle, and having a seat lock for insertion of a second connecting means, and having a securing tab; and

    a cover having a seat lock on one end to connect to the seat lock of said seat guide for holding the inserted second connecting means, which enable the cover to be removed and replaced, and the cover having a catch for interlocking with the securing tab on the seat guide to prevent the accessories holder from slipping out of the handle,wherein screw-on pressure produced by the positioner plate that is exerted on the toothed ridges on the ratchet-angle locking plate which are enmeshed with serrations of the multi-angle ratchet wheel allows firm adjustment over a varied range of angles.
