In one embodiment the inner collar has first and second inner collar contact surfaces (46, 50) in opposed disposition along a length of the inner collar. The outer collar is coupled to the inner collar and reciprocable between a locked position and first and second unlocked positions. ## Claims ### Claim 1 An adjustable stop, comprising: (a) an inner collar having first and second inner collar contact surfaces in opposed disposition along a length of the inner collar; and (b) an outer collar coupled to the inner collar and selectively reciprocable between a locked position and first and second unlocked positions. ### Claim 2 (depends on 1) The adjustable stop of claim 1, wherein the first inner collar contact surface is a shoulder and the second inner collar contact surface is a retaining clip. ### Claim 3 (depends on 1) The adjustable stop of claim 1, wherein the outer collar is normally positioned in the locked position. ### Claim 4 (depends on 3) The adjustable stop of claim 3, wherein the outer collar is positionable into the first unlocked position. ### Claim 5 (depends on 4) The adjustable stop of claim 4, wherein the outer collar is positionable into the second unlocked position. ### Claim 6 (depends on 1) The adjustable stop of claim 1, wherein the inner collar is adapted to receive a shaft with adjustment grooves. ### Claim 7 (depends on 1) The adjustable stop of claim 1, further comprising means for fine adjustment. ### Claim 8 (depends on 1) The adjustable stop of claim 1, further comprising an extension collar. ### Claim 9 An adjustable stop, comprising: (a) an inner collar having first and second inner collar contact surfaces; (b) an outer collar disposed on the inner collar; and (c) a biasing member disposed between the first and second inner collar contact surfaces and operatively contacting the outer collar. ### Claim 10 (depends on 9) The adjustable stop of claim 9, wherein the first inner collar contact surface is a shoulder and the second inner collar contact surface is a retaining clip. ### Claim 11 (depends on 9) The adjustable stop of claim 9, wherein the biasing member is a spring. ### Claim 12 (depends on 9) The adjustable stop of claim 9, wherein the outer collar includes a first outer collar contact surface and a second outer collar contact surface. ### Claim 13 (depends on 9) The adjustable stop of claim 9, wherein the biasing member includes a first biasing member contact surface and a second biasing member contact surface. ### Claim 14 (depends on 13) The adjustable stop of claim 13, wherein the collar is biased in a locked position, wherein the first biasing member contact surface is seated against the first inner collar contact surface, and the second biasing member contact surface is seated against the second inner collar contact surface. ### Claim 15 (depends on 14) The adjustable stop of claim 14, wherein the collar is positionable in a first unlocked position, wherein the first biasing member contact surface is seated against the first inner collar contact surface, and the second biasing member contact surface is seated against the second outer collar contact surface. ### Claim 16 (depends on 15) The adjustable stop of claim 15, wherein the collar is positionable in a second unlocked position, wherein the first biasing member contact surface is seated against the first outer collar contact surface, and the second biasing member contact surface is seated against the second inner collar contact surface. ### Claim 17 (depends on 9) The adjustable stop of claim 9, wherein the inner collar is adapted to receive a shaft with adjustment grooves. ### Claim 18 An adjustable stop, comprising: (a) an inner collar having first and second inner collar contact surfaces; (b) an outer collar disposed on the inner collar; and (c) means for biasing the adjustable stop into a locked position disposed between the first and second inner collar contact surfaces. ### Claim 19 An adjustable stop, comprising: (a) an inner collar having first and second inner collar contact surfaces in opposed disposition along a length of the inner collar; (b) an outer collar coupled to the inner collar and selectively reciprocable between a locked position and first and second unlocked positions; and (c) an extension collar adjustably attached to the inner collar. ### Claim 20 An adjustable stop, comprising: (a) an inner collar having a socket adapted to receive a shaft, the inner collar having a first inner collar contact surface and a second inner collar contact surface; (b) a biasing member disposed on the inner collar and moveably disposed between the first and second inner collar contact surfaces; and (c) an outer collar slidably coupled to the inner collar and adapted for reciprocating movement between a locked position and first and second unlocked positions. ### Claim 21 An adjustable stop, comprising: (a) an inner collar adapted to releasably receive a shaft with adjustment grooves, the inner collar having a first contact surface and a second contact surface; (b) a biasing member associated with the inner collar, the biasing member having a first contact surface and a second contact surface; (c) an outer collar having a first contact surface and a second contact surface, the outer collar being positionable between a locked position, a first unlocked position, and a second unlocked position relative to the inner collar; (d) wherein when the outer collar is in the locked position, the first biasing member contact surface is seated against the first inner collar contact surface, and the second biasing member contact surface is seated against the second inner collar contact surface; (e) wherein when the outer collar is in the first unlocked position, the first biasing member contact surface is seated against the first inner collar contact surface, and the second biasing member contact surface is seated against the second outer collar contact surface; and (f) wherein when the outer collar is in the second unlocked position, the first biasing member contact surface is seated against the first outer collar contact surface, and the second biasing member contact surface is seated against the second inner collar contact surface.
