Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a tool device, and more particularly to a tool device including a sleeve slidably attached onto a shaft for receiving and for driving various tool members of different sizes or diameters or dimensions.

2. Description of the Prior Art

Typical tool devices comprise a tool shank or socket having an engaging hole formed in one end thereof for receiving a tool bit or tool member, and a retaining or anchoring device attached onto the tool shank or socket for detachably securing the tool bit or tool member to the tool shank or socket.

For example, U.S. Pat. No. 6,270,085 to Chen et al. discloses one of the typical chuck devices for tool bits and also comprising a tube having a longitudinal engaging hole formed in one end thereof for receiving a tool bit or tool member, and a retaining or chuck device attached onto the tube for detachably securing the tool bit or tool member to the tube.

However, the longitudinal engaging hole of the tube may be used for receiving a tool bit or tool member of a single size only, and the tube may not be separated or disengaged from the chuck device such that the typical chuck device and the tube may not be replaced or changed with each other and may be used for receiving the tool bit or tool member of a single size only.

U.S. Pat. No. 6,637,755 to Chen et al. discloses another typical chuck device for tool bits and also comprising a socket having a longitudinal engaging hole formed in one end thereof for receiving a tool bit or tool member, and a retaining or chuck device attached onto the tube for detachably securing the tool bit or tool member to the socket.

However, similarly, the longitudinal engaging hole of the socket may be used for receiving a tool bit or tool member of a single size only, and the socket may not be separated or disengaged from the chuck device such that the typical chuck device and the socket may not be replaced or changed with each other and may thus be used for receiving the tool bit or tool member of a single size only.

The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional tool shanks or sockets or tool devices.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide a tool device including a sleeve slidably attached onto a shaft for receiving and for driving various tool members of different sizes or diameters or dimensions.

The shaft includes a retaining ring engaged onto the shaft and engageable with the control ferrule for limiting the control ferrule to slide relative to the shaft. The control ferrule includes two limiting grooves formed therein for engaging with the retaining ring and for limiting the control ferrule to move relative to the shaft and for maintaining the control ferrule either in engagement with only the shaft or in engagement with both the shaft and the tool member.

The tool member includes a peripheral depression formed therein and arranged for allowing the shaft to be tilted relative to the tool member to different angular position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to the drawings, and initially to FIGS. 1-3, a tool device 1 in accordance with the present invention comprises a shaft 10 including a socket opening 11 provided or formed in one end 12 thereof, and the socket opening 11 of the shaft 10 includes a non-circular cross section, such as a hexagonal cross section having one or more flat surfaces 13 formed therein, for slidably and/or rotatably or pivotally and tiltably or slantably receiving a non-circular spatial or three-dimensional engaging member 32 that is formed or provided on one end 31 of a driving tool member 30. The engaging member 32 of the tool member 30 includes a non-circular cross section, such as a hexagonal cross section having one or more curved or flat surfaces 33 formed in outer peripheral portion thereof (FIG. 1) for engaging with the corresponding non-circular socket opening 11 and/or the corresponding flat surfaces 13 of the shaft 10.

As shown in FIGS. 2 and 3, due to the slidable and/or rotatable or pivotal engagement between the curved surfaces 33 of the tool member 30 and the flat surfaces 13 of the shaft 10, the shaft 10 is allowed to be tilted relative to the engaging member 32 of the tool member 30, or relatively, the engaging member 32 of the tool member 30 is allowed to be tilted relative to the longitudinal axis 80 of the shaft 10 to different angular position, and also to allow the shaft 10 to be rotated or driven by the engaging member 32 of the tool member 30 when the tool member 30 is rotated or driven by the users and by the engagement of the curved surfaces 33 of the tool member 30 and the flat surfaces 13 of the shaft 10. The shaft 10 may include a cavity 14 formed therein and communicating with the socket opening 11 of the shaft 10 for receiving a magnetic member 15 therein.

For solidly attaching or securing the magnetic member 15 to the shaft 10, the magnetic member 15 may first be engaged into a barrel 16, and the barrel 16 may include a rough or serrated outer peripheral surface formed on the outer peripheral portion thereof for frictionally or solidly engaging into the cavity 14 of the shaft 10 and for allowing the barrel 16 and thus the magnetic member 15 to be easily and quickly attached or secured to the shaft 10 by forcing the barrel 16 into the shaft 10 and with a force-fitted engagement. The magnetic member 15 may be used to act with or to attract the engaging member 32 of the tool member 30 toward the shaft 10 for preventing the shaft 10 from being disengaged or separated from the engaging member 32 of the tool member 30, and/or for further positioning or anchoring the engaging member 32 of the tool member 30 to the shaft 10.

The tool member 30 may include one or more spring-biased projections (not shown) attached thereto and partially extended out from either of the curved surfaces 33 thereof for engaging with either of the flat surfaces 13 of the shaft 10 and for further suitably positioning or anchoring the engaging member 32 of the tool member 30 to the shaft 10. The tool member 30 further includes a peripheral depression 34 formed therein, such as formed in the middle portion thereof and located between the engaging member 32 and the shaft 30 for forming a diameter reduced neck portion 35. The formation or the provision of the neck portion 35 and the peripheral depression 34 in the tool member 30 allows the tool member 30 to be suitably and selectively slanted or tilted relative to the longitudinal axis 80 of the shaft 10 to any selected or different angular position.

The shaft 10 includes a peripheral groove 17 formed in the inner peripheral portion thereof for receiving or engaging with a clamping or retaining member 18 therein, and the retaining member 18 is slidably engaged in the peripheral depression 34 of the tool member 30 and selectively engageable with the engaging member 32 of the tool member 30 (FIG. 3) for anchoring and securing the engaging member 32 of the tool member 30 to the shaft 10 and for preventing the engaging member 32 of the tool member 30 from being disengaged from the shaft 10. The tool member 30 further includes a peripheral shoulder or protrusion 36 formed thereon, such as arranged to have the peripheral depression 34 of the tool member 30 to be formed and located between the peripheral protrusion 36 and the engaging member 32 of the tool member 30.
