[0006] Preferably, the ejector rod sleeve is provided in a variety of sizes. By setting the ejector rod sleeve in a variety of sizes, the size of the ejector rod sleeve can be selected according to the size of the workpiece, and it can be replaced at any time. It can be installed and disassembled, which is convenient to use and improves work efficiency.

[0007] Preferably, the fixed die sleeve is circular with an annular protrusion at the upper end and a through hole in the middle. The guide sleeve is an annular sleeve and is hollow. The annular protrusion on the fixed die sleeve can position and fix the bushing, improving the insertion efficiency.

[0008] Compared with the prior art, the beneficial effects of the present utility model are as follows: When in use, place the hollow jack on the arm at the disassembly position, put the guide sleeve on the lead screw, pass the lead screw through the middle hole of the bushing, and then successively put the fixed die sleeve and the ejector rod sleeve on the lead screw. Position and pull the ejector rod sleeve through the bolt, operate the hollow jack, and pull out the bushing on the arm through the ejector rod sleeve. Guide the bushing through the guide sleeve to ensure the stability during pulling. The size of the ejector rod sleeve can be changed according to the size of the workpiece, and it can be replaced at any time. It can be installed and disassembled, which is convenient to use and improves the disassembly, assembly and maintenance efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
