[0089] When the connecting piece 522 is driven by the pressing driving mechanism 521 to move downward along the installation cavity 11, the connecting piece 522 drives the hinged part 512 of the pressing piece 51 to rotate downward along the clockwise direction, and the pressing part 511 of the pressing piece 51 rotates upward along the clockwise direction due to the hinged part in the middle of the pressing piece 51 being hinged in the installation cavity 11. During the rotation of the pressing part 511, the end part thereof extends out of the installation cavity 11 and presses against the bottom surface of the lower steel bar 220, so as to push the lower steel bar 220 upward to the preset welding position and make the lower steel bar 220 tightly contact the upper steel bar 210. When the welding is completed, the connecting piece 522 is driven by the pressing driving mechanism 521 to move upward along the installation cavity 11, the connecting piece 522 drives the hinged part 512 of the pressing piece 51 to rotate upward along the counterclockwise direction, and the pressing part 511 of the pressing piece 51 rotates downward along the counterclockwise direction due to the hinged part in the middle of the pressing piece 51 being hinged in the installation cavity 11. During the rotation of the pressing part 511, the end part thereof is separated from the bottom surface of the lower steel bar 220 and is retracted into the installation cavity 11, so as to avoid the obstruction caused by the positioning process of the first positioning piece 20 and / or the second positioning piece 30 in guiding the upper steel bar 210 or the lower steel bar 220 into the accommodating groove.
