Title: ELASTIC SHEET FIXING-TYPE FINE ADJUSTMENT DEVICE FOR STRENGTHENING ARC-SHAPED TELESCOPIC ROD
Abstract:
An elastic sheet fixing-type fine adjustment device for strengthening an arc-shaped telescopic rod, comprising a telescopic sleeve and bases disposed at two ends of the telescopic sleeve, respectively; an inner tube of the telescopic sleeve is provided thereon with at least one elastic sheet, an outer tube of the telescopic sleeve is provided thereon with a plurality of size adjustment holes, one of which may be selectively clamped to an elastic sheet; and a fine adjustment device is connected between at least one of the bases and the telescopic sleeve. By providing the elastic sheet on the inner tube and providing the size adjustment hole on the outer tube, it is possible, by means of clamping the elastic sheet to the selected size adjustment hole, to adjust the length of the entire telescopic sleeve of the arc-shaped telescopic rod without using attachment screws; when the arc-shaped telescopic sleeve needs to be disassembled and assembled, all that is needed to change the length of the telescopic sleeve is pressing the elastic sheet, thus no damage is caused during disassembly and assembly, and the reusability rate is high.
