In order to facilitate the axial precession of the sleeve 5 on the socket head 4, preferably, the end of the sleeve 5 is provided with a hand wheel or handle portion 21. In order to ensure that the hand wheel or handle portion 21 does not rotate the sleeve 5 out of the socket head 4 during operation, more preferably, on the socket head 4, a stop is protruded along the circumference near the hand wheel or the handle portion 21. Boss 22. The locking device 420 further includes a buckle seat ring 3 of an annular structure sleeved on the periphery of the sleeve 5, a claw pin seat 23 disposed on the buckle seat ring 3, and a buckle extending through the inner hole of the claw pin holder 23. The pawl pin 6, and the pawl 7 pivotally mounted to the pawl pin 6, are fastened to the sleeve 5 by the pawl seat ring 3. Preferably, a plurality of pawl pin holders 23 are symmetrically and evenly arranged on the pawl seat ring 3. In this embodiment, the two claw pin holders 23 are symmetrically disposed on the buckle seat ring 3. Of course, a plurality of other claw pin holders 23 may be simultaneously disposed on the buckle seat ring 3 to meet different situations. And need. The bottom of the claw 7 is provided with a hook-like surface 15 of a hook-like structure, and the claw 7 can be pivoted about the pawl pin 6 by a certain angle. At this time, the buckle seat ring 3 and the sleeve 5 have a small gap in the circumferential direction, and the buckle seat ring 3 can rotate around the sleeve 5. Meanwhile, in order to avoid the relative movement of the buckle seat ring 3 relative to the sleeve 5 in the axial direction, preferably, the sleeve 5 further includes a second stepped shaft section 16, and the shoulder of the second stepped shaft section 16 is resisted by the buckle An end surface of the claw ring 3; the locking device 420 further includes a retaining ring 8, and the other end surface of the claw seat ring 3 is abutted by the end surface of the retaining ring 8. The retaining ring 8 is fixed to the socket head 4 by an interference fit. Of course, the retaining ring 8 can also be fixed to the socket head 4 by various fixing means such as screws or rivets. The end surface of the boss 9 further includes a claw surface 12, and the claw surface 12 forms a snap connection with the hook surface 15 of the claw 7, thereby preventing the fixed interface 1 from being disengaged from the socket head 4. When assembling the combined toilet interface of the present invention, referring again to FIG. 1, the sleeve 5 is sleeved on the socket head 4 by a screw connection, and the pawl 7 is fitted on the sleeve 5 through the buckle seat ring 3 and other fasteners. Then, the stop ring 8 is installed in sequence, and the interface cap 2 is mounted on the socket head 4; the fixed interface 1 is installed in the external equipment through the device portion 11 at the end (not shown) the end of the tube. In the operation of the squeezing operation, the interface cap 2 and the fixed interface 1 are mated with the convex cone surface 10 through the concave tapered surface 14. Thereafter, the pawl 7 is pivoted down, and the hand wheel or the handle portion 21 is rotated, so that the sleeve 5 drives the pawl 7 to axially advance on the socket head 4 until the hook surface 15 of the pawl 7 is buckled to the boss. At the claw surface 12 of the pin 9, the engaging surface of the interface cap 2 and the fixed interface 1 which are butted by the concave tapered surface 14 and the convex outer surface 10 are kept in close contact relationship. Finally, the socket head 4 is connected to the hose of the reservoir by means of the hose assembly section 40. When the combined toilet interface of the present invention is detached, it is opposite to the process at the time of assembly. Preferably, referring to FIG. 4, in order to perform the docking of the operation interface 420 of the claw fixing structure with the fixed interface 1, the hook structure of the end of each of the claws 7 is inserted into the claw provided with the fixed interface 1.

In this case, the hook-like structure provided at the end of the claw 7 can enter the preliminary position where the claw surface 12 of the fixed interface 1 is hooked. The spring body 72 herein can be in a variety of configurations, such as reed devices, torsion spring devices, and the like. In order to perform the disengagement of the operation interface 420 of the claw fixing structure and the fixing interface 1, the hand holding the hand wheel or the handle portion is required to rotate the hand wheel or the handle portion so that the hooking surface 15 of the claw 7 is fixed. The claw-butting surface 12 of the interface 1 is disengaged from the abutting buckle, and the hooking end of the claw 7 which is inwardly engaged by the reed device 72 or the torsion spring is pivoted outward to facilitate the disengagement from the fixing interface 1 The table 9 is configured to perform convenient operation of the hand when the operating interface 420 is disengaged from the fixed interface 1. Preferably, the claw 7 is further provided with an everted extension 71 at an end away from the hooking surface 15, and the hand wheel is rotated by the human hand. At the same time as the handle portion 21, the eversion extension portion 71 can be operated by an individual finger to be pivoted against the elastic force of the reed device 72, so that the hooking surface 15 of the pawl 7 is disengaged from the pawl surface 12 of the fixed interface 1 , to achieve separation of the operating interface and the fixed interface. Preferably, referring to FIG. 5, in order to obtain the docking function of the buckle 7 fixing structure operation interface 42 and the fixed interface 1, it is inconvenient to overcome the possible rotation of the buckle 7 around the circumference of the sleeve 5 to the docking operation.

The fixing interface 1 further includes two anti-rotation bosses 100 protruding along the circumference thereof, and the two anti-rotation bosses 100 are oppositely disposed. And the distance between the two is equal to or greater than the width of the claw 7. When the docking of the operating interface and the fixed interface is performed, the claw 7 is first inserted between the two blocking bosses 100 to avoid the claws. The improper rotation of 7 causes docking of the operating interface to increase the inconvenience. When the hand wheel or the handle portion 21 is rotated to a certain position, the hooking surface 15 of the claw 7 and the claw surface 12 are fastened to each other, so that the docking interface of the docking is implemented. The joint faces are taken to be closely adhered to each other to obtain a close contact state. Referring to FIG. 6 and FIG. 7 together, the fixed interface 1, the operating interface 42 and the locking device 420 of the second embodiment of the combined faecal interface of the present invention are in other structural forms.
