The specific embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, non-polar sleeve of the present invention comprises that cylindrical shell 1, three carve piece 2, three torsion springs 3, spring baffle rings 4 and regulate tube 5.
Cylindrical shell 1 is columnar structured, comprise anterior flange 11, middle cylinder 12 and back cylinder 13, the middle cylinder slightly larger in diameter is in the back cylinder diameter, the front portion of middle cylinder evenly is interval with three breach 121, is provided with the first step 111 and the second step 112 that dwindle formation gradually between anterior flange and the middle cylinder; Middle cylinder is respectively equipped with projection 122 in the same direction side of three breach 121, and projection is provided with arc-shaped slot 1221 in the side of its contiguous breach.The oral area of cylindrical shell 1 is provided with the hexagonal structure 113 adaptive with six-sided nut.Back cylinder 13 is provided with and is used for the internal structure 131 that links to each other with handle.
Carve in three breach 121 that piece 2 is disposed in an evenly spaced relation in middle cylinder and be movably connected by a pin 6 and anterior flange 11 respectively for three, the one side of carving piece 2 is a convex surface 21, and another side is plane 22, and the plane is inside; One side of carving piece is provided with arc raised line 23.Pin 6 is connected between arc raised line 23 and the anterior flange 11.
Three torsion springs 3 are separately positioned on three and carve between piece 2 and the middle cylinder 12, and an end of each torsion spring links to each other with middle cylinder is rotatable, in the hole of other end string correspondence on carve piece 21 accordingly.
Regulating tube 5 is sleeved on the middle cylinder 12, its front end slides with the first step 111 of cylindrical shell and links to each other, sliding with spring baffle ring 4 and link to each other in the rear end, regulates the tube inwall and evenly be interval with three arc bumps 51 of thickening gradually, and the lateral surface of each arc bump 51 is suitable with the convex surface 21 of respectively carving piece 2.On the inwall of regulating the tube rear portion, be provided with a circle groove (not shown come out), regulate tube by its groove is enclosed within realize on the spring baffle ring with cylindrical shell between slip link to each other.
