The invention discloses a large-stroke multifunctional fastener which comprises an outer sleeve, a first connecting part is arranged at the left end of the outer sleeve, a first threaded through holeis formed in the first connecting part, a second connecting part is arranged at the right end of the outer sleeve, and a second threaded through hole opposite to the first threaded through hole in rotating direction is formed in the second connecting part. An inner sleeve is arranged in the outer sleeve, an outer thread matched with the first threaded through hole is arranged on the outer surfaceof the inner sleeve, a first bearing part is arranged at the left end of the inner sleeve, a torsion bar is arranged in the inner sleeve, and an outer thread matched with the second threaded through hole is arranged on the outer surface of the torsion bar; a second bearing part is arranged at the right end of the torsion bar; and a handle is arranged on the outer wall of the outer sleeve. By adopting a sleeve type structure, the telescopic stroke is doubled under the condition that the length is not increased, and the problems that an original fastener is short in stroke and troublesome to operate are solved.
本发明公开了一种大行程多功能紧固器,包括外套管,所述外套管的左端设有第一连接部,所述第一连接部上设有第一螺纹通孔,所述外套管的右端设有第二连接部,所述第二连接部上设有与第一螺纹通孔的旋向相反的第二螺纹通孔。所述外套管的内部设有内套管,所述内套管的外表面设有与第一螺纹通孔相适配的外螺纹,所述内套管的左端设有第一承载部件,所述内套管的内部设有扭力杆,所述扭力杆的外表面设有与第二螺纹通孔相适配的外螺纹,所述扭力杆的右端设有第二承载部件;所述外套管的外壁上设有手柄。本发明采用套筒式结构,在不增加长度的情况下,使伸缩行程增加一倍,解决了原有紧固器行程短、操作麻烦的问题。
