The maximum diameter of the through holes 14 is not smaller than the diameter of the balls 15. The through holes 14 The minimum aperture is smaller than the diameter of the balls 15, and the through holes 14 and the balls 15 are uniformly distributed on the hollow sleeve 12. An annular annular groove 16 is further formed on the outer surface of the hollow sleeve 12 away from one end of the first end surface η. The outer surface of the first connecting member 10 is provided with a recessed portion 18 and communicates with the first end surface 13. A recessed portion 18 is provided at the bottom of the recessed portion 18, and the first counterbore 182 extends in a direction perpendicular to the first end surface n. • At least one arcuate chute 19 is defined in the first end surface 13. In this embodiment, the circular arc chutes 19 are two and symmetrically distributed on the first end surface 13. Referring to FIG. 3, the ferrule 20 includes an inner surface 22 and a second end surface 4. A plurality of bumps 222 are uniformly disposed on the surface 22, and recesses 224 are formed between the adjacent bumps 222. The second end face % is provided with two openings 241, 242 and at least one hole 244. In the present embodiment, the holes 2 are privately located two and are symmetrically distributed on the second end face 24. Referring to FIG. 4, the second connecting member 3 includes a body 31 and a fixed end 32 of a cylindrical 刼laJ column fixedly connected to the body 31. The fixed end 32 can be received in the hollow sleeve 12 Two of the ^ ^. The outer side wall of the fixed end 32 is provided with an annular groove 324, and the end of the main body 31 is provided with at least one opening 326. Name: Taipu Pricer 丄 In the present embodiment, the opening 326 is two solid and symmetrically distributed at the ends of the fixed end 32. I see Figure 5' for an enlarged locking block. The locking block 4 〇 the first surface 42 and a second surface opposite the first surface 42

44 and a side surface 46 between the first surface 44 and the first surface 42. The first surface 42 is provided with a Φ but a baby κ. The upper surface 6 is further provided with a locking portion 422, and the second surface 44 is provided with a second counterbore 442. Referring to FIG. 6 and FIG. 7 , the ferrule 20 is sleeved on the hollow sleeve 12 and the second end surface 24 of the ferrule is opposite to the first end surface 13 . A first gear 50 is embedded in the recessed groove 16 and a force is applied to the inner surface 22 of the ferrule 20 against the inner surface of the ferrule to prevent the ferrule 2 轴向 from moving axially relative to the first connecting member. . That is, the inner surface 22 of the retaining groove 16, the retaining ring 50, and the ferrule 20 together form a limiting structure for limiting the axial displacement of the heart ferrule 20 relative to the first connecting member 1 . The first connecting member 10 is provided with at least one hole 17 disposed adjacent to the second end surface 13, at least one positioning block m passing through the hole 17 and protruding; & the inner surface of the connecting member 10, The positioning block is in close fitting with the hole 17. The second connecting member 30 is inserted into the first connecting member 1 , and the opening 326 of the connecting member 30 is locked at the positioning block 171 , so that the second connecting member 30 is It is fixed to the first connecting member 1 in the circumferential direction. In the present embodiment, the hole 17, the positioning block 171 and the opening 326 are two square 12 1322726 Z structures, and are symmetric in the fiscal direction (four). The hole 17 and the position block Π=opening 326 together form a positioning device. In other embodiments of the present invention, the positioning device may also be the other (four) framing center to connect the first connection 〇 and the second connection member 30 to The fixing is fixed in the circumferential direction, for example, in the fixing body (4), or is fixed to the inner surface of the first connecting member 1 by other fixing means such as material, screw connection or the like.

The fixed end 32 of the second connector 30 is inserted into the hollow portion of the hollow sleeve 12. Rotating the ferrule 20, when the ridge of the ferrule 2 is opposite to the position of the first hole =1, the bump 222 is in contact with the balls 15 p, and the 222 can be The ball 15 abuts against the groove 324 0 of the second connection, thereby axially fixing the second connecting member to the first connecting member; when the ferrule 222 of the ferrule 2 and the first connecting member When the position of the through hole is deviated, the balls 15 fall into the recess 224 of the inner surface 22 of the ferrule 2', and the second connecting member can be moved from the first connecting member to the first connecting member. 6 is further disposed at the recessed portion 18 of the first connecting member 10, one of the I 47 is fixed in the second counterbore 442 of the locking block 40, and the other end is inserted into the first counterbore of the first connecting member 10. 182, and a clearance fit with the first hole 182, the spring 48 is disposed between the bottom of the first sink π 182 / between the pin 45. The locking portion 422 of the locking block 4 can be received in the opening 241 or 242 of the two sets 20. The locking block, the pin 〇, the elastic dam 48 and the recessed portion 18 of the first connection #1〇, the first counterbore and the openings 241, 242 of the sleeve 20 together form a locking device for limiting the circumference of the ferrule 20 The rotation of the direction. 13 ί 322 726 粕 图 图 726 粕 粕 , , , , , , , , , , , , , , 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少The end of the 篑25 is gj.
