Adjustable prying bar

Abstract

An adjustable prying bar includes a prying head having an arcuate body, a flat tipped lower end a lug at upper end wherein the lug has a circular depression and an inverse stop ring on upper portion and inner thread on lower portion, a handle rotatably engaged with the upper end of the prying head having flat front end with a hexagon hole therein engaged within the lug of the prying head, and a checking mechanism including an upper cover, a lower cover, a hexagon plate and a spring separately engaged with the lug and the hexagon hole of the handle wherein the hexagon plate has a stop ring engageable with stop ring of the lug. Thereby, the angle between the prying head and the handle enables to adjust for larger or smaller than 90 degrees.

Claims

1. An adjustable prying bar comprising: a prying head having an arcuate body, a flat stipped lower end, a lug at upper end wherein said lug has a circular depression with a small central bore in a upper portion and a stop ring formed with a plurality of inverse radial teeth on opposite side of said depression, and a large central bore in a lower portion having thread on inner periphery;a handle having a flat front end engaged with the lug of said prying bar including a hexagon hole therein;a checking mechanism disposed in said lug for facilitating said prying bar to perform angle adjustment between said prying head and said handle.

2. The adjustable prying bar as recited in claim 1 wherein said checking mechanism comprising; an upper cover covering the circular depression of said lug having a small central bore and secured by a screw;a hexagon plate engaged into the hexagon hole of said handle having a stop ring formed with a plurality of positive radial teeth engageable with the stop ring of said lug and a circular ring projected downward from a center of bottom;a lower cover covering lower portion of said lug having outer threads on a circular wall engaged with the threads on inner periphery of said lug and a cylindrical projection on upper center of bottom;a spring engaged between said hexagon plate and said lower cover and wrapped on said circular ring in said cylindrical projection.

3. The adjustable prying bar as recited in claim 1 wherein the angle between said prying head and said handle may be adjusted for larger or smaller than 90 degrees.
