When the fixing assembly 600 passes through the fixing groove 503, the second block 601d is first inserted into the fixing groove 503, after the second block 601d enters the fixing groove 503, the taper sleeve 602a positioned on the limit post 601c is then inserted into the fixing groove 503, the taper sleeve 602a enters the fixing groove 503 from one end of the small taper portion 602a-1 with smaller diameter until the positioning block 602a-3 arranged near one side of the large taper portion 602a-2 is blocked, at this time, the taper sleeve 602a is rotated until the positioning block 602a-3 is aligned with the positioning groove 602a-4, and the positioning block 602a-3 slides along the positioning groove 602a-4 when following the movement of the taper sleeve 602a without affecting the insertion of the taper sleeve 602a, and after the taper sleeve 602a penetrates the fixing groove 503 to move down, a part of the positioning block 602a-3 on one side of the large taper portion 602a-2 is still left in the fixing groove 503;
then, when the fixing assembly 600 needs to be pulled out of the fixing groove 503, the positioning block 602a-3 can be rotated around the inner wall of the fixing groove 503 by the conical sleeve 602a, so that after the positioning block 602a-3 is rotated to be aligned with the positioning groove 602a-4, the positioning block 602a-3 is completely pushed into the positioning groove 602a-4, and at the moment, the large conical part 602a-2 of the conical sleeve 602a is aligned with the fixing groove 503, so that pulling out is facilitated.
In sum, through setting up locating piece 602a-3 and the cooperation of constant head tank 602a-4 and using, during the installation, the locating piece 602a-3 slides along constant head tank 602a-4 when following toper cover 602a and remove, does not influence toper cover 602 a's insertion, can accurately make toper cover 602 a's big cone 602a-2 and fixed slot 503 align when dismantling, has solved toper cover 602a and has lifted the easy problem of misalignment with fixed slot 503 when dismantling.
