This application claims priority to Chinese Patent Application No. 201610650528.2, filed Aug. 10, 2016, the disclosure of which is incorporated herein by reference in its entirety.
The present disclosure relates to powered screwdrivers, and more particularly to an interference fit screwdriver tip and a powered screwdriver using the same.
A conventional method for securing and screwing a screw head is to use a magnetic screwdriver tip to attract the screw. However, the method of using the magnetic screwdriver tip is not suitable for non-magnetic elements.
Many aspects of the disclosure can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the exemplary embodiments described herein. However, it will be understood by those of ordinary skill in the art that the exemplary embodiments described herein can be practiced without these specific details. In other instances, methods, procedures, and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the exemplary embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features of the present disclosure.
With reference to
The engaging portion 130 has at least one end. In the present exemplary embodiment, the engaging portion 130 is cross-shaped and therefore has four ends. In other exemplary embodiments, the engaging portion 130 is flat and has two ends.
The number of the at least one resilient members 133 is equal to the number of the at least one end of the engaging portion 130. The at least one resilient member 133 corresponds to and is attached to the at least one end of the engaging portion 130. The engaging portion 130 is made of cemented carbide, and the resilient member 133 is made of a resilient plastic or a resilient metal. In the present exemplary embodiment, the resilient member 133 is a wedge-shaped block.
With reference to
With reference to
The exemplary embodiments shown and described above are only examples. Many details are often found in the art such as the other features of a powered screwdriver. Therefore, many such details are neither shown nor described. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the detail, especially in matters of shape, size, and arrangement of the parts within the principles of the present disclosure, up to and including the full extent established by the broad general meaning of the terms used in the claims. It will therefore be appreciated that the exemplary embodiments described above may be modified within the scope of the claims.
