Embodiment

To understand and understanding in order having the purpose of this utility model, feature and effect further, below conjunction with figs. to be enumerated embodiment, describe in detail as after.

At first, please extremely shown in Figure 4 by Fig. 1, it includes: one first housing 10, a driving link 20, a driven member 30, one second housing 40 and a rapid pipe joint 50, wherein, the inside of first housing 10 is hollow, and to form a containing space 11, an end of containing space 11 is embedded with a bearing 12, to make this end slightly bring together, the other end is extended with one first adapter section 13 outward; Driving link 20 is placed in the containing space 11 of first housing 10, the bearing 12 that can pass first housing 10 with the extension bar 21 that makes driving link 20 1 ends stretches out outward again, can be used for connecing by this extension bar 21 and establish electronic or pneumatic tool, and can be driven to rotate to make driving link 20; The periphery of driving link 20 is arranged with a bearing 22 equally again, and the end face that the other end is provided with one first hemisphere type cam, 23, the first hemisphere type cams 23 is departing from the teat 24 that the central position then is provided with half spherical shape; One end of driven member 30 is extended with a lock 31, the other end is provided with one second hemisphere type cam 32, the end face of the second hemisphere type cam 32 is departing from the projection 33 that the central position is provided with half spherical shape, fixing on the driven member 30 again has one to enlarge the inner hexagonal hole nut 34 that arranges, and be arranged with a bearing 35 and a spring 36, the periphery of this inner hexagonal hole nut 34 is provided with second adapter section 37, and spring 36 then is set in this end near lock 31, ends to make spring 36 produce to support with bearing 35; Second housing, 40 inside are for hollow and form a containing space 41, one end of containing space 41 is embedded with a bearing 42, can slightly bring together to make this end, the other end inwall is provided with one the 3rd adapter section 43, this second housing 40 provides driven member 30 to insert with containing space 41, and makes driven member 30 utilize lock 31 to pass bearing 42 stretching out in second housing 40 more outward; When driven member 30, first housing 10 produce assembly with the 3rd adapter section 43 of second adapter section 37, first adapter section 13 and second housing 40 respectively, military order first housing 10, second housing 40 can be involutory, provide gripping to constitute a complete handle, and utilize the location of inner hexagonal hole nut 34, then make driven member 30 only can produce axial translation, and can't be rotated by stopper, and this driven member 30 in the past the outer lock 31 that stretched out connect and establish rapid pipe joint 50.
