신속히 작동가능하게 탄성적으로 맞물린 스크류 - 너트 메카니즘

The supporting sheet and up - end - it is supported by moreover, the supporting sheet it is uniformly arranged in the screw, and the transverse section surrounding of the screw are dried while passing through the means (the thing like the sleeve up - end - in which side includes the preventive measure to the axial direction) that the preventive measure (antishift means) of side is installed in order not to change and the screw the supporting hole within the mobile feet (fit), and the semi screwnut and business enterprise - end - via the sleeve which is positioned between the sleeve (up-and-down sleeve) and includes one or more semi- screwnuts (semi-nuts) equipped with the opening/closing means which automatically can go up and can down, and the up-and-down guide member, fixed to the guide groove of the semi- screwnut capable of the supporting body including the supporting arm, the supporting hole, and the apparatus connected to the carrier like the pivot axis (O1), and top and bottom the sliding the supporting sheet (supporting seat) and the opening/closing device for being made of the location constraint element (position limiting member) and business enterprise - end -. Is the axial direction of the screw. And two or more semi- screwnuts are arranged in the screw circumference of core The screw - screwnut mechanism in which the automatic open-close device for the semi- screwnut which is used in order to be mobile in the rapidly at the same time, automatically control open and close operation of the semi- screwnut as to the screw - screwnut mechanism which elastically goes in gear and is controlled in terms of mechanically, program - includes the actuating element, and the separation operation apparatus like the rigidity CELP - locking actuating element and which moreover, the automatic open-close device for the semi- screwnut includes to the actuating element designating the operation of the automatically being controlled in terms of program - like the sleeve up - end -, the pole, the overload separating device of the automatic synchronization including the spring hoop etc, the upturn stroke restricting skid (upward stroke limiting device), and the protective gear and screw is the addition the high speed or the apparatus for changing speed in which the inside trade (thread) which the semi- screwnut is extended to about peripheral part half, and the sliding guide groove inducing the operation up - end - and the power up - end - comprise the delivered actuating element. The actuating element is operated on the semi- screwnut and elastically goes in gear like spring. The separation operation apparatus like the rigidity CELP - locking actuating element rigidly locks the semi- screwnut CELP - and the cam profile which accurately separates the semi- screwnut or the link mechanism. As to the protective gear and screw is the addition the high speed or the apparatus for, it makes it possible at a low speed.
