Abstract

A sliding sleeve or collar which is cylindrical and has an elongated guide or channel fluidly connecting the outer annular wall with the inner annular wall of the sleeve is disclosed. A connector having at least one open end and an elongated slot with a floor and a pin guide through the floor is further disclosed. The pin guide is open to the inside of the connector. Between the sleeve and the slot is a pin having a pin head visible through the elongated guide and two opposing spring arms of a size and shape to fit in said slot, and a pin body which movable fits inside pin guide.

First claim

What is claimed is:

1. A method of reversibly locking a tool-mounting connector, the method comprising:
placing the distal end ( 37 ) of a movable pin assembly ( 30 ) having a pin body ( 36 ), a pin head ( 38 ) with an extended distal end, a first curved spring arm ( 32 ) and a second curved spring arm ( 34 ) extending therefrom into a pin guide ( 27 ) of an elongated connector ( 20 );
the elongated connector configured with an open end ( 24 ) forming a tool guide ( 26 ), a slot ( 25 );
sliding a moveable sleeve ( 50 ) having pin catch guide ( 60 ) onto the elongated connector;
providing a lock latch ( 65 ) in between the first catch region and the second catch region wherein the two regions remain fluidly connected;
wherein the pin head is a catch which extends above the spring arms and is a size and shape to pass through the lock latch only by temporarily displacing it whereby sleeve movement is restricted;
wherein the pin catch guide is ovoid with a first catch region ( 66 ) and a second catch region ( 68 ) and,
wherein the arms are asymmetrical, with one arm above the other arm.

2. The method of claim 1 , the method further comprising placing a tool shaft ( 102 ) with retention fixture ( 100 ) inserted into the tool guide.

3. The method of claim 1 , wherein the distal end of the pin ( 37 ) is curved.

4. The method of claim 1 , the method further comprising forming one spring arm nearer to the pin head then the other spring arm whereby the spring arm near the pin head, when compressed, will urge the distal end of the pin into a retention fixture.

5. The pin connector of claim 4 , wherein the arms are positioned opposite one another on the distal end.

6. The method of claim 1 , the method further comprising forming one spring arm further from the pin head then the other spring arm whereby the spring arm further from the pin head, when compressed, will not urge the distal end of the pin into a retention fixture.

7. A method of reversibly locking a tool-mounting connector, the method comprising:
placing the distal end ( 37 ) of a movable pin assembly ( 30 ) having a pin body ( 36 ), a pin head ( 38 ) with an extended distal end, a first curved spring arm ( 32 ) and a second curved spring arm ( 34 ) extending therefrom into a pin guide ( 27 ) of an elongated connector ( 20 );
the first spring arm further comprises:
a curved member ( 210 ) with a proximal end ( 201 ) and a distal end ( 202 );
wherein the proximal end is affixed to the pin assembly;
wherein the distal end is unaffixed and oriented below the height of the proximal end on the pin assembly;
the elongated connector configured with an open end ( 24 ) forming a tool guide ( 26 ), a slot ( 25 );
sliding a moveable sleeve ( 50 ) having pin catch guide ( 60 ) onto the elongated connector;
wherein the pin catch guide is ovoid with a first catch region ( 66 ) and a second catch region ( 68 );
wherein the arms are asymmetrical, with one arm above the other arm; and,
whereby the sleeve sliding over the curved member compresses the spring arm against the floor ( 28 ) of the slot thereby pushing the distal end of the pin into the open tool guide.

8. A method of reversibly locking a tool-mounting connector, the method comprising:
placing the distal end ( 37 ) of a movable pin assembly ( 30 ) having a pin body ( 36 ), a pin head ( 38 ) with an extended distal end, a first curved spring arm ( 32 ) and a second curved spring arm ( 34 ) extending therefrom into a pin guide ( 27 ) of an elongated connector ( 20 );
the second spring arm further comprises:
a curved member ( 200 ) with a proximal end ( 211 ) and a distal end ( 212 );
wherein the proximal end is affixed to the pin assembly;
wherein the distal end is unaffixed and oriented below the height of the proximal end on the pin assembly;
the elongated connector configured with an open end ( 24 ) forming a tool guide ( 26 ), a slot ( 25 );
sliding a moveable sleeve ( 50 ) having pin catch guide ( 60 ) onto the elongated connector;
wherein the pin catch guide is ovoid with a first catch region ( 66 ) and a second catch region ( 68 );
wherein the arms are asymmetrical, with one arm above the other arm; and,
whereby the sleeve sliding over the curved member compresses the spring arm against the floor not pushing the distal end of the pin into the open tool guide.
