Under this arrangement, the first abutting segment and the second abutting segment abut against an outer periphery of a tool bit, so that the tool bit does not depart from the engaging room easily during operation.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a driving head, and more particularly to a driving head with an elastic buckle in which the elastic buckle does not depart from an engaging room thereof when a user changes a tool head.

2. Description of Related Art

A conventional driving head with a positioning member comprises a driving head which has a stepped outline. The driving head is divided into two portions. An assembling portion is formed on one of the two portions of the driving head. An engaging groove is recessed inwardly in the assembling portion for engaging with a tool bit. A positioning member is assembled in a predefined segment of the assembling portion, so that the tool bit does not depart from the engaging groove during the operation. A flange is defined on the assembling portion and nears to the engaging groove. The positioning member is U-shaped. The engaging groove has an engaging slot defined therein. A shape of the engaging slot corresponds to another shape of the positioning member. The positioning member is received in the engaging slot. Under this arrangement, the tool bit is engaged with the engaging groove securely because the positioning member abuts against an outer periphery of the tool bit.

However, the conventional driving head with a positioning member has one disadvantage described as following.

When the tool bit is departed from the engaging groove, the positioning member is moved with the movement of the tool bit easily, and the user has to repeatedly reassemble the positioning member with the engaging groove, so that the user operates the conventional driving head with a positioning member inconveniently.

The present invention has arisen to mitigate and/or obviate the disadvantages of the conventional.

SUMMARY OF THE INVENTION

The main objective of the present invention is to provide a driving head with an elastic buckle.

To achieve the objective, a driving head with an elastic buckle comprises a driving head and an elastic buckle, the driving head having an engaging room defined therein, the engaging room having a first limiting slot and a second limiting slot recessed therein, the first limiting slot has a first limiting hole opened therethrough, the elastic buckle being assembled with the engaging room, the elastic buckle having a connecting segment, a first abutting segment and a second abutting segment, the first abutting segment being received in the first limiting slot, the second abutting segment being received in the second abutting slot, the first abutting segment and the second abutting segment connecting to two ends of the connecting segment respectively, the first abutting segment having a first abutting portion defined thereon which is slightly bent inwardly. Wherein, the first limiting slot is opposite to the second limiting slot; the first limiting slot and the second limiting slot are recessed from an opening of the engaging room toward a bottom of the engaging room; the second abutting segment further has a second abutting portion defined thereon which is slightly bent inwardly, so that the first abutting portion and the second abutting portion abut against the tool bit so as to prevent the tool bit from moving relative to the engaging room freely; the second limiting slot further has a second limiting hole opened thereon, so that when the second abutting segment is moved to the second limiting hole, another end of the elastic buckle is engaged with the second limiting hole so as to prevent the elastic buckle from thoroughly detaching from the engaging room; the engaging room further has an annular limiting groove defined around an inner wall thereof; the annular limiting groove communicates with the first limiting slot and the second limiting slot separately; the first abutting portion of the first abutting segment is bent toward the engaging room as arc-shaped; the first abutting portion of the first abutting segment is bent toward the engaging room as V-shaped; the second abutting portion of the second abutting segment is bent toward the engaging room as arc-shaped; the second abutting portion of the second abutting segment is bent toward the engaging room as V-shaped. Under this arrangement, the first abutting segment and the second abutting segment abut against an outer periphery of a tool bit, so that the tool bit does not depart from the engaging room easily during operation; when the tool bit is departed from the engaging room, the elastic buckle does not depart from the engaging room easily because one end of the elastic buckle is engaged with the first limiting hole.

DETAILED DESCRIPTION OF THE INVENTION

Referring toFIGS. 1-5, a driving head with an elastic buckle comprises a driving head1and an elastic buckle2. The driving head1has an engaging room11defined therein. The engaging room11has a first limiting slot12and a second limiting slot13recessed therein. The first limiting slot12has a first limiting hole111opened therethrough. The elastic buckle2is assembled with the engaging room11. The elastic buckle2is U-shaped. One end of the elastic buckle2is engaged with the first limiting hole111. The elastic buckle2has a connecting segment21, a first abutting segment22and a second abutting segment23. The first abutting segment22is received in the first limiting slot12. The second abutting segment23is received in the second abutting slot13. The first abutting segment22and the second abutting segment23connect to two ends of the connecting segment21respectively. The first abutting segment22has a first abutting portion221defined thereon which is slightly bent inwardly. Under this arrangement, the first abutting segment22and the second abutting segment23abut against an outer periphery of a tool bit3, so that the tool bit3does not depart from the engaging room11easily during operation; since one end of the elastic buckle2is engaged with the first limiting hole111, the elastic buckle2does not depart from the engaging room11easily when the tool bit3is departed from the engaging room11.

The detailed characteristics of the present invention are further described as following.

The first limiting slot12is opposite to the second limiting slot13. The first limiting slot12and the second limiting slot13are recessed from an opening (not numbered) of the engaging room11toward a bottom of the engaging room11.

The second abutting segment23further has a second abutting portion231defined thereon which is slightly bent inwardly, so that the first abutting portion221and the second abutting portion231abut against the tool bit3so as to prevent the tool bit3from moving relative to the engaging room11freely.

Referring toFIGS. 4-6, the elastic buckle2is assembled in the engaging room11. The connecting segment21of the elastic buckle2is abutted against the bottom of the engaging room11. The first abutting portion221of the first abutting segment22is bent toward the engaging room11as arc-shaped. A distance between one end of the elastic buckle2and the opening of the engaging room11is longer than another distance between the first limiting hole111and the opening of the engaging room11. The second abutting portion231of the second abutting segment23is bent toward the engaging room11as arc-shaped. Therefore, when the tool bit3is assembled with the engaging room11, the outer periphery of the tool bit3is abutted against the first abutting portion221of the first abutting segment22and the second abutting portion231of the second abutting segment23, wherein the first abutting segment22is opposite to the second abutting segment23so as to abut against the tool bit3uniformly, so that the tool bit3does not depart from the engaging room11easily during operation.

As shown inFIG. 6, when the tool bit3is going to be departed from the engaging room11, the tool bit3is pulled from the engaging room11, so that the elastic buckle2is moved upward with the movement of the tool bit3because the elastic buckle2is securely abutted against the tool bit3; meanwhile, the connecting segment21of the elastic buckle2is detached from the bottom of the engaging room11; thereby, when one end of the elastic buckle2is moved to the first limiting hole111with the movement of the tool bit3, the first abutting segment22is engaged with the first limiting hole111, so that the elastic buckle2does not detach from the engaging room11thoroughly with the detachment of the tool bit3.

Referring toFIGS. 7-9, the second limiting slot13further has a second limiting hole112opened thereon, so that when the second abutting segment23is moved to the second limiting hole112, another end of the elastic buckle2is engaged with the second limiting hole112so as to prevent the elastic buckle2from thoroughly detaching from the engaging room11, so that a user operates the present invention conveniently.

Referring toFIGS. 7-9, the engaging room11further has an annular limiting groove14defined around an inner wall thereof. The annular limiting groove14communicates with the first limiting slot12and the second limiting slot13separately. The annular limiting groove14overlaps with the first limiting slot12and the second limiting slot13. Therefore, the elastic buckle2is securely engaged with the engaging room11when the first abutting segment22and the second abutting segment23are received into the annular limiting groove14.

Referring toFIG. 1andFIG. 7, outlines of the first abutting segment22and the second abutting segment23are defined as a bent-shaped or as a V-shaped in which the first abutting segment22and the second abutting segment2.3bend toward the engaging room11respectively (The outlines of the first abutting segment22and the second abutting segment23are not limited by the present invention).
