- 12. A tool device for use with a tool having a connecting portion thereon comprising:
a hollow body; a retention member pivotally mounted in the hollow body; a spring biasing the retention member to a retention position to retain the tool on the tool device; a shoulder portion on the retention member biased by the spring to engage the connecting portion on the tool and to retain the tool on the tool device; and an actuator for shifting the retention member to a tool release position to shift the shoulder portion from its retaining position to a release position.
- 13. A tool device in accordance with claim 12 comprising:
eject cam portions on the pivotally mounted retention member movable to eject the tool from the tool device.
- 14. A tool device in accordance with claim 12 comprising:
turning cam portions for engaging the tool and for turning the cam through a predetermined increment.
- 15. A tool device in accordance with claim 12 wherein the retention member comprises:
a plate with an enlarged opening therein to allow insertion of an enlarged head on the tool through the enlarged opening; a wall portion of the enlarged opening on the plate to retain the tool head; and a stationary receiving portion on the tool device to receive the enlarged head when the tool is attached.
- 16. A combination of a tool device and a tool comprising:
a flat blade tool; a body on the tool device releasable connected to a top side of the flat blade tool; at least one working surface on the flat blade tool; portions on the tool and on the tool device cooperating to turn the flat blade tool relative to the tool device to change the angle of attack to the work or to position a different working surface into use; portions on the tool and on the tool device cooperating to releasably retain the tool on the tool device; and a push button actuator on the body operable with a first movement to turn the tool blade and operable with a second movement to release the blade tool from the body.
- 17. A combination in accordance with claim 16 wherein the body comprises:
the body being smaller in area than the area of the tool and being positioned centrally over the top of the blade tool and having portions thereof configured to fit within a palm and to fingers of the user.
- 18. A combination in accordance with claim 16 wherein the body of the tool device comprises:
a handle portion projecting outwardly on an upper side of the body.
- 19. A combination in accordance with claim 16 wherein the actuator is pushed with a lighter force through a predetermined distance to cause a turning of the tool blade and wherein the actuator is pushed with a larger force and through a longer distance to eject the blade tool from the body.
- 20. A combination in accordance with claim 16 wherein the blade tool comprises:
a substantially planar body of one piece; and an integral central post projecting upwardly from the planar body for connection to the body of the tool device.
- 21. A combination in accordance with claim 20 wherein the blade tool is formed with a plurality of integral teeth spaced about the upstanding post to cooperate with the tool device to turn the tool through a predetermined increment.
- 22. A tool for releasable connection to a handle device comprising:
an integral one piece body; a plurality of working surfaces on different portions of the body to be turned into a use position; a releasable retention portion on the body for connection to the handle device to retain and release the body from the handle device; and turning portions on the body for cooperation with the handle device to turn the body relative to the handle device.
- 23. A blade tool in accordance with claim 22 comprising:
the integral one piece body being made of a molded plastic material.
- 24. A blade tool in accordance with claim 22 wherein the integral one-piece body is made of stamped metal.
- 25. A blade tool in accordance with claim 22 wherein the releasable retention portion comprises:
an upstanding post on the body for insertion into the handle device.
- 26. A blade tool in accordance with claim 22 wherein a plurality of teeth are provided on the body for cooperation with a handle device to turn the blade tool relative to the handle device.
- 27. A method of using a tool having multiple working surfaces and releasably connected to a tool device having a manual handle portion; the method comprising:
providing the manual handle portion on the tool device for manipulation by the user to present a first working surface or an angle of attack on the tool to the work; providing a releasable and turnable tool for connection to the handle with the multiple working surfaces thereon; moving an actuator on the tool device with a first movement to turn the tool to present a second working surface or a second angle of attack to the work; and moving an actuator with a second movement to release the tool from the tool device.
- 28. A method in accordance with claim 27 wherein:
the releasing of the tool from the tool device comprises a pushing of the tool away from the tool device to snap off the tool from the device without the operator having to touch the tool.
- 29. A method in accordance with claim 27 comprising:
