DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIGS. 1, 2, 3, and 4, the tool handle self-containing a set of screwdriver bits, in accordance with an embodiment of the present invention, includes a handle 10 for holding by the user and a set of screwdriver bits stored in the handle. The inside of the handle 10 is made of hard plastic and the surface of the handle 10 is covered with an elastic plastic skin so as to allow the user to securely grip the handle 10 without having the handle 10 slip in the user's hand. The bottom 11 of the handle 10 is covered with metal and provided with a fixed hole 12. In the hole 12 there is magnetic material for attracting ferrous substances. Preferably, one face of the handle 10 has a receiving groove 13 and an open hole 132, while an opposite face has a through hole 131. The open hole 132 is larger than the through hole 131 so that the set of screwdriver bits 20 can be inserted in the open hole 132 and emerge out the through hole 131 partly.
The set of screwdriver bits 20 includes a base 21, a pillar 22 provided on the base 21 and a plurality of holding parts 23 provided on the base 21. The base 21 of the set of screwdriver bits 20 has two layers 211, 212; the upper layer 211 is made of hard plastic and the lower layer 212 is made of the same elastic plastic as the surface of the handle 10 is covered. In the embodiment of the present invention, the holding part 23 on the base 21 is a pair of detents with curved inner side, which can lock the bottom of the screwdriver bit 30. There are four holding parts 23 in the embodiment of the present invention. Because one holding part 23 can lock one screwdriver bit 30 and there is an additional screwdriver bit 30 usually provided at the fixed hole 12, so there are at least five screwdriver bits 30 with different sizes and shapes such as PHILIP'S® head, flathead, hexagonal head . . . etc. in the tool handle of the embodiment.
In addition, at the upper end of the pillar 22 on the base 21 there is a step portion 24 and the top face 25 of the pillar 22 is oval in shape so that the step portion 24 of the pillar can match and insert in the through hole 131 of the receiving groove 13 in a specific position. If the direction of insertion is not right, the top face 25 of the pillar 22 then can not be inserted in the through hole 131 of the receiving groove 13.
After the set of screwdriver bits 20 and the receiving groove 13 are assembled, the bottom of the base 21 and the surface of the handle 10 can make the tool handle have a continuous and smooth surface, i.e. the bottom of the base 21 can just fill up the open hole 132 of the receiving groove 13. If the device is viewed from the open hole 132 side of the receiving groove 13, the set of screwdriver bits 20 can engage and hide in the handle 10 so that it does not easily slip off under the case of shaking or colliding. If the device is viewed from the groove hole 131 side of the receiving groove 13, the top face 25 of the pillar 22 becomes a pressing face at the through hole 131 of the receiving groove 13. If the pressing face 25 is pressed, the set of screwdriver bits 20 can easily move out from the receiving groove 13. Therefore, each screwdriver bit 30 cannot be easily lost and the handle 10 has pleasant appearance after assembling.
In application, the screwdriver bit 30 can be taken out from the holding part 23 and inserted in the fixed hole 12 on the bottom 11 of the handle. By rotating the handle 10, the various screw heads can be fastened or loosed. In addition, the magnetic material in the fixed hole 12 can firmly attract the screwdriver bit 30 so that the latter does not easily slip off. Therefore, in this preferred embodiment, the handle self-containing a set of screwdriver bits is both practical and convenient.
It must be noticed that the preferred embodiment stated above cannot be used to limit the scope of the present invention. The all changes and modifications to the embodiment by the persons who are skilled at this field must be regarded as the content of the present invention. The scope of the patent right applied by the present invention should be defined by the accompanying claims.
Therefore, the present invention has the following advantages:

    1. After the set of screwdriver bits is received in the handle, the device has pleasant appearance and the set of screwdriver bits does not easily slip off. When the pressing face at one side of the handle is pressed, the set of screwdriver bits can be easily moved out from the handle. Its operation is simple and convenient.
    2. The number and size of the screwdriver bits provided at the set of screwdriver bits can be changed and replaced according to the demand of the user. It is convenient for the user to change for various needs.
    3. After the screwdriver bit is inserted and locked in the fixed hole of the handle, it can be attracted up by magnetic material so that it cannot easily slip off. The inconvenience due to loosening can be decreased.
    4. The tool handle self-contained a set of screwdriver bits according to the present invention suits for various hand tools. It makes hand tool possess not only one function but also increase the additional value of hand tools, so it has very high utilization value in industry.


To sum up, the present invention indeed can accomplish its expected objects to provide a tool handle self-contained a set of screwdriver bits. The set of screwdriver bits is convenient to lock in or move out from the tool handle. The tool handle self-contained a set of screwdriver bits according to the present invention can suits for various hand tool.
