[0020] The transmission member includes a rotating seat 13, a swing rod 16, a first spring, a clamping block 14 and a slot 17. The rotating seat 13 is rotatably connected to the mounting seat 18. A handle 15 is provided on the rotating seat 13. The middle part of the swing rod 16 is rotatably connected to the handle 15 through a latch. A plurality of slots 17 are provided, and they are distributed on the mounting seat 18 at equal angles. The clamping block 14 is located at one end of the swing rod 16 close to the rotating seat 13, and the clamping block 14 is in an L-shaped structure. The first spring is located at one end of the swing rod 16 away from the rotating seat 13, and the two ends of the first spring are respectively in conflict with the swing rod 16 and the handle 15. When it is necessary to adjust the flow rate of water in the bolt body 1, the handle 15 is used to adjust the flow rate of water in the bolt body 1. Hold one end of the handle 15 and the swing rod 16 and compress the first spring, so that the other end of the swing rod 16 drives the clamping block 14 to disengage the slot 17, and then rotate the handle 15, so that the rotating seat 13 synchronously drives the transmission rod 19 to rotate a certain angle. Multiple slots 17 can be engaged with the clamping block 14 as needed to control the rotation angle of the transmission rod 19, so as to adjust the inclination angle of the sealing plate 12 and the inner hole of the bolt body 1 to achieve flow regulation.

After the sealing cover 6 is inserted into the elbow pipe 11, the knob 26 is rotated so that the knob 26 can push the sliding block 27 to slide in the threaded tube 31. At this time, the second spring 33 is compressed, and one end of the sliding block 27 cooperates with the concave groove 35, so that the sealing cover 6 cannot be separated from the elbow pipe 11 outward. When the knob 26 is rotated in the opposite direction, the sliding block 27 can be separated from the concave groove 35 under the action of the second spring 33, so that the sealing cover 6 can be removed from the elbow pipe 11. A threaded hole is provided at one end of the locating pin 30. The locating pin 30 can be easily removed from the mounting boss 32 by relying on the threaded hole, and the operation is simpler and more convenient.
