The inner wall of shell 13 is rotationally connected with by shaft, and then during expansion plate 23 is without use, staff
Expansion plate 23 is squeezed, starts to shrink the contained spring 26 of expansion plate 23, and then so that expansion plate 23 is in contraction state, and store
On the inner wall of shell 13, then, staff can rotate support rod 22, and support rod 22 is carried far from one end of shaft and is stretched
On plate 23, and then expansion plate 23 can be fixed, the state for remaining retracted it, it avoids influencing subsequent filter sheet
The installation of body 12.
In the present embodiment, during use, firstly, making expansion plate 23 remain retracted state by support rod 22,
And the top cover 11 at 13 top of shell is opened, filter ontology 12 is placed on engagement plate 14, and engagement plate 14 is fixed on
The inside of shell 13, and then under the action of engagement plate 14, filter ontology 12 can be fixed on inside shell 13, and
At the input end interface of the opening alignment filter ontology 12 of 23 one end of expansion plate, then, when staff carries out electricity
When the access of source line, firstly, it is necessary to power supply line is inserted among the wire casing 25 inside expansion plate 23, also, wire casing 25 is provided with
It is multiple, it is spaced from each other between each wire casing 25 by partition 24, and then form wire casing 25, therefore, different input lines can insert
Enter among different wire casings 25, it, will be between each power supply line under the action of partition 24 when among power supply line insertion wire casing 25
Be spaced from each other, so can be to avoid mutually knotting between multiple power supply lines the case where, then, staff again will be inserted into wire casing 25
Internal power supply line pulls out, and is inserted into the input end interface of filter ontology 12, after the insertion of power supply wire body, work
Personnel make one end of support rod 22 be detached from expansion plate 23 in rotation support rod 22, and the spring 26 inside expansion plate 23 is made to start to reset
It stretches, and support telescopic plate 23 is made to start to stretch, and then one end of expansion plate 23 is made to ride over the outer wall of filter ontology 12, and
It using the setting of wire casing 25 and expansion plate 23, put the power supply line of input can only by the wire casing 25 in expansion plate 23
Set, so define input power cord place length, avoid power supply line it is too long influence filter ontology 12 safety with
And normal use.
Further, housing unit 1 further includes top cover 11 and engagement plate 14, and top cover 11 is covered on the top of shell 13, rank
Fishplate bar 14 is fixed on inside shell 13, and filter ontology 12 is fixed on engagement plate 14 close to the one side wall of top cover 11.
In the present embodiment, during use, firstly, the opening by top cover 11 puts filter ontology 12
It is placed on engagement plate 14, and engagement plate 14 is fixed on the inside of shell 13, and then under the action of engagement plate 14, can will filter
Wave apparatus ontology 12 is fixed on inside shell 13.
Further, telescopic component 2 further includes support rod 22, and one end of support rod 22 is rotationally connected with shell 13 by shaft
Inner wall, and support rod 22 and shaft are respectively positioned on expansion plate 23 close to the side of top cover 11.
In the present embodiment, during expansion plate 23 is without use, staff can squeeze expansion plate 23, make
The contained spring 26 of expansion plate 23 starts to shrink, and then so that expansion plate 23 is in contraction state, and be accommodated in the inner wall of shell 13
On, then, staff can rotate support rod 22, support rod 22 be carried on expansion plate 23 far from one end of shaft, Jin Erbian
Expansion plate 23 can be fixed, the state for remaining retracted it, avoid the installation for influencing subsequent filter ontology 12.
Further, the length of support rod 22 is greater than the spacing between expansion plate 23 and shaft.
In the present embodiment, by the restriction to 22 length of support rod, so that support rod 22 is after turning, one end can
