## Abstract

A handpiece holder, which provides easy access to a medical, dental, or industrial handpiece, is replaceable and rotatable to hold handpieces in different angled positions.

## Claims

### Claim 1

A holder for handpiece devices, comprising:
a disc base having a perimeter and a face;
a biased pawl positioned on the perimeter of the disc base;
a housing having an interior opening; and
a gear tooth perimeter within the interior opening of the housing, the biased pawl interfacing with the gear tooth perimeter providing a three-hundred and sixty degree range of rotation of the housing with respect to the disc base, the biased pawl engaging with the gear tooth perimeter to selectively secure the housing in a desired rotational position within the three-hundred and sixty degree range.

### Claim 2 (depends on 1)

The holder for handpiece devices recited in claim 1, further comprising a through-hole within the disc base.

### Claim 3 (depends on 2)

The holder for handpiece devices recited in claim 2, further comprising a clip connected with the housing.

### Claim 4 (depends on 3)

The holder for handpiece devices recited in claim 3, the handpiece holder further comprising a center post having a first end and a second end, the first end connected to the housing within the interior opening and extending through the through-hole of the disc base.

### Claim 5 (depends on 4)

The holder for handpiece devices recited in claim 4, the center post further comprising mechanical fingers on the second end of the center post, the mechanical fingers interfacing with a support structure to rotationally and releaseably secure the handpiece holder to the support structure.

### Claim 6 (depends on 5)

The holder for handpiece devices recited in claim 5, the disc base further comprising positioning structure extending from the face of the disc base and interfacing with the support structure to rotationally fix the disc base to the support structure.

### Claim 7 (depends on 6)

The holder for handpiece devices recited in claim 6, the support structure further comprising an open hole, and the positioning structure comprising a post that interfaces with the open hole.
