Brief description of the drawings
Fig. 1 is the structural representation of the embodiment of the present invention；
Fig. 2 is the partial enlarged drawing at I in Fig. 1.
Embodiment
As depicted in figs. 1 and 2, screwed retaining ring, coordinates with bolt 9 or stud, including inner sleeve 1 and is enclosed on outside inner sleeve 1
Outer sleeve 2, the inner surface of the inner sleeve 1 is provided with internal thread, and the barrel of the inner sleeve 1 is provided with multiple through holes 3, described
It is installed between the upper end of inner sleeve 1 and the outer sleeve 2 under upper baffle ring 4, the inner sleeve 1 and the outer sleeve 2
Lower baffle ring 7 is provided between end, the lower gear ring 7, which is provided with to be inserted with multiple pilot holes 5, each described pilot hole 5, is seated post
6, it is described to be seated the retainer ring 18 that the lower end of post 6 is connected to below the lower gear ring, the inner sleeve 1, outer sleeve 2, on
Steel ball 8 is filled with cavity between baffle ring 4 and the lower baffle ring 7, the outer wall of the steel ball 8 is pressed through the through hole 3
Tightly in the outer surface of bolt 9 or stud, the inwall of the outer sleeve 2 is provided with to be released steel ball 8 when direction is moved on nut edge
The promotion face of bolt 9 or stud outer surface is pressed against, the upper surface of the upper baffle ring 4 is installed with clamp nut 10, institute
State and gap is provided between retainer ring 18 and the bolt 9 or stud, between the lower baffle ring 7 and the bolt 9 or stud
It also is provided with gap.
The lower end that the promotion face includes being located at the inner wall lower of outer sleeve 2 tilts the He of the first inclined-plane 11 to inner sleeve 1
The upper end that lower end is connected with first inclined-plane upper end is to inclined second inclined-plane 12 of the inner sleeve 1.
11 provided with the bullet 13 upwardly extended on first inclined-plane.The taper surface of bullet 13 is further such that nut
Steel ball 8 is pressed against bolt 9 or stud outer surface along releasing when direction is moved.
The outer surface for being seated post is provided with resilient sleeve.Resilient sleeve has elastic force so that between being seated between post and steel ball
Gap is smaller.Not shown in the resilient sleeve figure.
The post that is seated includes ballhead 14, and the lower section of the ballhead is provided with connecting rod 15, and the lower section of the connecting rod 15 is set
There is push rod 16, the diameter of the push rod 16 is more than the diameter of the connecting rod 15.Because the diameter of push rod 16 is more than the connecting rod 15
Diameter, be seated post insertion after steel ball block connecting rod so that the insertion for being seated post is more firm.
The inner peripheral surface of the upper baffle ring 4 is provided with the internal thread coordinated with the bolt 9 or stud.
The upper end of the inner surface of the outer sleeve 2 is provided with internal thread, and the outer surface of the upper baffle ring 4 is provided with and the overcoat
