Abstract

An immobilizer tool set includes a plurality of retention blocks. Each retention block of the plurality of retention blocks includes a first plate, a guide pin extending from the first plate, and a second plate on the guide pin and configured to slide on the guide pin relative the first plate. A spring is between the first plate and the second plate.

First claim

The invention claimed is:

1. An immobilizer tool set comprising:
a plurality of retention blocks configured for assembly about a center axis, wherein each retention block of the plurality of retention blocks comprises:
a first plate comprising:
a head extending circumferentially between a first end and a second end relative the center axis, and extending axially from a first surface to a second surface relative the center axis; and
a stem extending radially inward from the head toward the center axis;
wherein the guide pin extends axially from the stem;

a guide pin extending from the first plate;
a second plate on the guide pin and configured to slide on the guide pin relative the first plate, the second plate comprising:
a body extending circumferentially between a first end and a second end relative the center axis, and extending axially from a first surface to a second surface relative the center axis; and
a projection extending radially inward from the body toward the center axis;
wherein the guide pin extends axially into the projection;

a second guide pin extending axially from the stem and into the projection; and
a spring between the first plate and the second plate.

2. The immobilizer tool set of claim 1 , wherein the plurality of retention blocks form a circle about the center axis.

3. The immobilizer tool set of claim 1 , wherein a circumferential length of the head tapers radially inward.

4. The immobilizer of claim 1 , wherein the spring is around the guide pin and compressed between the first plate and the second plate.

5. The immobilizer tool set of claim 1 , wherein the body is circumferentially shorter than the head.

6. The immobilizer tool set of claim 5 , wherein the first plate of a second retention block of the plurality of retention blocks comprises a head that is circumferentially shorter than a body of the second plate of the second retention block.

7. The immobilizer tool set of claim 1 and further comprising:
a gripper tool comprising:
a bar extending between a first end and a second end;
a first jaw connected to the first end of the bar;
a first handle connected to the second end of the bar;
a tube extending between a first end of the tube and a second end of the tube, wherein the bar is longer than the tube and the bar extends through the tube;
a second jaw connected to the first end of the tube;
a second handle connected to the second end of the tube; and
a second spring extending between the second end of the tube and the first handle.

8. The immobilizer tool set of claim 7 , wherein the first jaw comprises a first nub, the first plate comprises a first recess configured to receive the first nub, the second jaw comprises a second nub, and the second plate comprises a second recess configured to receive the second nub.

9. An immobilizer tool set comprising:
a plurality of retention blocks, wherein each retention block of the plurality of retention blocks comprises:
a first plate;
a guide pin extending from the first plate;
a second plate on the guide pin and configured to slide on the guide pin relative the first plate; and

a spring between the first plate and the second plate; and
a gripper tool comprising:
a bar extending between a first end and a second end;
a first jaw connected to the first end of the bar;
a first handle connected to the second end of the bar;
a tube extending between a first end of the tube and a second end of the tube, wherein the bar is longer than the tube and the bar extends through the tube;
a second jaw connected to the first end of the tube;
a second handle connected to the second end of the tube; and
a second spring extending between the second end of the tube and the first handle.

10. The immobilizer of claim 9 , wherein the spring is around the guide pin and compressed between the first plate and the second plate.

11. The immobilizer tool set of claim 9 , wherein the first jaw comprises a first nub, the first plate comprises a first recess configured to receive the first nub, the second jaw comprises a second nub, and the second plate comprises a second recess configured to receive the second nub.

12. The immobilizer tool set of claim 9 , wherein the plurality of retention blocks are configured for assembly about a center axis, and wherein the first plate of at least one retention block of the plurality of retention blocks comprises:
a head extending circumferentially between a first end and a second end relative the center axis, and extending axially from a first surface to a second surface relative the center axis; and
a stem extending radially inward from the head toward the center axis,
wherein the guide pin extends axially from the stem.

13. The immobilizer tool set of claim 12 , wherein the plurality of retention blocks form a circle about the center axis.

14. The immobilizer tool set of claim 12 , wherein a circumferential length of the head tapers radially inward.

15. The immobilizer tool set of claim 12 , wherein the second plate of the at least one retention block comprises:
a body extending circumferentially between a first end and a second end relative the center axis, and extending axially from a first surface to a second surface relative the center axis; and
a projection extending radially inward from the body toward the center axis,
wherein the guide pin extends axially into the projection.

16. The immobilizer tool set of claim 15 , wherein the at least one retention block further comprises:
a second guide pin extending axially from the stem and into the projection.

17. The immobilizer tool set of claim 15 , wherein the body is circumferentially shorter than the head.

18. The immobilizer tool set of claim 17 , wherein the first plate of a second retention block of the plurality of retention blocks comprises a head that is circumferentially shorter than a body of the second plate of the second retention block.
