Referring to fig. 1 to 6 together, the housing of the present invention will now be described. The housing includes: a first conductive cylinder (cylinder: hollow tubular object) body 11, a second conductive cylinder body 12 detachably sleeved on the first conductive cylinder body 11, and a third conductive cylinder body 13 sleeved and slidably arranged on the first conductive cylinder body 11; the second conductive cylinder 12 is detachably fixed on the third conductive cylinder 13; the first conductive cylinder 11 is provided with a first conductive stopping portion 111, the third conductive cylinder 13 is provided with a second conductive stopping portion 131, and the conductive elastic sheet 2 is clamped between the first conductive stopping portion 111 and the second conductive stopping portion 131.

Further, referring to fig. 1 to 6, as an embodiment of the housing of the present invention, the second conductive stopping portion 131 is annular, and the second conductive stopping portion 131 is annularly disposed on the inner wall of the third conductive cylinder 13.
