ABSTRACT:
The invention herein relates to a kind of multi-angle all-purpose ratchet screwdriver that consists mainly of a serrated ratchet wheel on a screwdriver chuck, a ratchet-angle locking plate at the hinged juncture between the handle and the screw driver chuck, and a threaded positioner plate which, when tightened, exerts pressure on the ratchet wheel and the ratchet-angle locking plate, thus, securing the ratchet-angle locking plate against the ratchet wheel on the screwdriver chuck, while also attaining the objective of securing the ratchet-angle locking plate to the screwdriver chuck at various angles. Furthermore, there is a removable accessories holder inside the handle that is secured by a guide seat held against the accessories holder by a snap-fit fast-open cover, which allows the quick removal and replacement of the cover by simply pulling or pushing, and the accessories holder below can then be naturally slid out of the handle, without falling out unnecessarily, to attain the objective of changing screwdriver accessories.
