Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a chair, more particularly to a drummer's chair.[0003]2. Description of the Prior Art[0004]Drummer's chairs are provided for drummers. These chairs are usually height-adjustable, just as the chair shown in U.S. Pat. No. 5,738,326. The chair mainly includes a threaded stem and a clamping device. The clamping device surrounds the threaded stem. The clamping device may secure the threaded stem with a screw and a nut. To avoid sliding of the threaded stem, users usually firmly secure the nut with a very strong force. The force may probably destroy the thread of the screw or the nut, especially when the height of the chair has been adjusted for many times. Thus, the life time of the chair is limited.[0005]The present invention is, therefore, arisen to obviate or at least mitigate the above mentioned disadvantages.SUMMARY OF THE INVENTION[0006]The main object of the present invention is to pro...
