An inserted support, comprising:
- a base plate with two opposite lateral sides, having an upright edge surrounding a periphery thereof, having a reduced inward part on each respective opposite lateral sides, the upright edge at each of the reduced inward parts being formed with an opposite recess, and being crossed by a central elongated base groove between the reduced inward parts such that a base opening is formed to intersect with the upright edge, and both ends of the upright edge at the opening have a recess such that a projection is formed respectively;
- two supporting blocks, being opposite and corresponding to each other, each of the supporting blocks basically being a supporting post with an end, and the supporting post at the end thereof has a locating head extending with a width therefrom slightly greater than that of the base groove, the locating head at both lower lateral sides thereof provided with a lower recess respectively to connect with the supporting post and the lower recesses having a height thereof not less than the thickness of the base plate, and the locating heads have a locating pin extending outwardly with an outer diameter respectively;
- a volute disk with a facial side and a bottom side, being circular, the bottom side thereof being provided with a volute groove and the width of the volute groove being greater than the outer diameter of each locating pin, and having a diameter greater than the distance of the two lateral sides of the base plate;
- a facial plate, having a shape corresponding to the base plate, and having an extending downward edge surrounding a periphery thereof corresponding the upright edge on the base plate, having two facial recesses at the downward edge corresponding to the base recesses on the upright edge, and a support part being provided thereon;
- wherein, the opposite supporting blocks are engaged with the base groove from the base opening, the volute groove receives the locating pins while the volute disk is laid on the locating heads, the facial plate covers the base plate and both the plates are engaged with each other by way of fastening screws, two opposite outlets being formed by the corresponding base recesses and the facial recesses, and part of the volute disk exposes outside from the outlets for being capable of moving the volute disk to displace the supporting blocks and adjust the engagement of the supporting posts.
