The liquid containing box 43 is cylindrical and has an opening facing the top plate 41, a coupling agent is contained in the liquid containing box 43, one side of the liquid containing box is fixedly connected with a hinge column 44, and the other side of the liquid containing box is connected with a liquid outlet column 45 in a sliding manner. All the hinge columns 44 are jointly rotated to penetrate through hinge shafts 46, the top plate 41 and the bottom plate 42 are both provided with connecting holes 5 for the hinge shafts 46 to penetrate through, one end of each hinge shaft 46 penetrating through the top plate 41 is fixedly connected with a limiting disc 461, and the other end penetrating through the bottom plate 42 is in threaded connection with a limiting nut 462.

As shown in fig. 2, the instrument body 1 is fixedly connected with four limit hooks 47 for limiting the liquid outlet column 45 on one side of the liquid containing box 43, each limit hook 47 includes a connecting strip 471 fixedly connected with the instrument body 1, a hook 472 is fixedly connected to one side of the connecting strip 471, which faces the liquid containing box 43, and one side of the hook 472, which deviates from the instrument body 1, is set as a guide inclined plane 4721. When the liquid containing box 43 rotates to be tightly attached to the instrument body 1, the hook part 472 is tightly attached to the side surface of the liquid outlet column 45 departing from the instrument body 1, so that the limiting hook 47 can limit the liquid outlet column 45, the liquid containing box 43 is difficult to rotate and is in a state of storing the coupling agent; one of the limit hooks 47 is bent, and the corresponding liquid containing box 43 rotates around the hinge shaft 46 and is dislocated with respect to the other liquid containing boxes 43, so that the opening thereof is opened. Different types of coupling agents are respectively contained in the liquid containing boxes 43, and the coupling agents of different types are carried together, so that the liquid containing boxes are convenient to use under different conditions.

As shown in fig. 3 and 4, a pressure plate 48 is provided in the liquid containing box 43, a seal groove 481 is provided on the side surface of the pressure plate 48, and a seal ring 49 is mounted on the seal groove 481 so as to be in close contact with the inner wall of the liquid containing box 43.
