First, as shown in Fig. 5, the housing 110 is divided into a first body 110a and a second body 110b that are detachably assembled vertically, and the first body 110a and the second The coupling surface of the body 110b is fixed by the fixing member 120 so that the assembled state of the first body 110a and the second body 110b can be maintained.

The fixing member 120 includes a coupling protrusion 121 provided at the bottom of the sidewall of the second body 110b by combining the first body 110a and the second body 110b. In the state of being inserted into the insertion groove 122 formed at the top, the coupling protrusion 121 is fixed or fixed according to the rotational position of the operation piece 124 inserted into the shaft groove 123 at the bottom of the insertion groove 122 Can be released.

In particular, as shown in FIG. 24, when the housing 110" is rotated in a downward direction, one side of the insertion groove 118 is in close contact with one side of the insertion protrusion 226, and the housing 110" as shown in FIG. When it is rotated in the direction, the other side of the insertion groove 118 is configured to be in close contact with the other side of the insertion protrusion 226, so that the vertical rotation range of the housing 110" can be limited.

Meanwhile, the upper surface of the side wall portion 221 of the second base 220 may be formed as an inclined surface so as not to interfere with the housing 110 ″ when the housing 110 ″ is vertically rotated. At this time, in a state in which the housing 110" is rotated downward, as shown in FIG. 24, the lower surface of one side of the housing 110" is in close contact with the upper surface of the side wall part 221, and the housing 110" is When the lower surface of the other side of the housing 110" is in close contact with the other side of the upper surface of the side wall part 221 in the state of being rotated upward, the housing 110") by using the side wall part 221 of the second base 220 It is possible to limit the range of vertical rotation.
