Then, the broken roller blind shaft is placed on the inner side through the placement groove 202 arranged on the upper end of the translation sliding block 201, thereby improving the stability of the placement of the broken roller blind shaft. Subsequently, when cutting and repairing the fracture, the rotation wheel 204 installed on the inner side of the mounting groove 203 can rotate the broken roller blind shaft left and right, so that the circumferential angle of the cutting and repairing does not change, thereby affecting the straightness and strength of the repaired roller blind shaft.
