Specific embodiment
The invention will be further described with the following Examples.
The novel compositions nut that the present embodiment is provided, including inner sleeve 1, overcoat 2 and guiding collar 3.
See Fig. 1 to Fig. 3, overcoat 2 is in hexagonal cylinder, and inner sleeve 1 is in cylinder.Overcoat 2 is set in outside inner sleeve 1, overcoat 2 with it is interior
Set 1 is connected through a screw thread, and the madial wall of inner sleeve 1 is provided with the screw thread coordinated with bolt 10, and the externally threaded lift angle of inner sleeve 1 is than its internal thread
It is small.
The lateral wall of the tail end of inner sleeve 1 is provided with the chute 4 that opening extends positioned at the tail end end face and towards the head end direction of inner sleeve 1,
Preferably, side wall of the chute 4 through inner sleeve 1.The madial wall of guiding collar 3 has a guide part 5, and guide part 5 is towards the side of the head end of inner sleeve 1
To extension.The inner side of guide part 5 is smaller than the internal diameter of guiding collar 3 with the distance of the axis of inner sleeve 1（See Fig. 3）.Guide part 5 and chute 4
Slidably engage.
