The assembly of the top opening sleeve and the compression nut, the structure of the split type expansion sleeve is that a disc stop is set at the lower end of the expansion tube, and an inverted cone end hole is set at the tube hole at the upper end of the expansion tube. The expansion tube is split into two halves along its axis, and the conical end of the top opening sleeve cooperates with the inverted cone end hole of the split type expansion sleeve. The upper end of the tension bolt passes through the center hole of the support plate, and the installed clamping nut cooperates with the support plate. The assembly of the tension bolt installation is installed from the inner hole of the copper sleeve, the bottom surface of the disc stop of the split type expansion sleeve is higher than the bottom step surface of the base shaft hole, and the top surface of the disc stop is lower than the lower end surface of the copper sleeve.

[0005] The method steps implemented by the utility model are described as follows:

[0006] 1. Screw the M6*60 stud into the threaded hole of the base;

[0007] 2. Assemble the split expansion sleeve, top sleeve, tension bolt (M8*60 hexagonal screw), gasket and press nut (M8 nut), and pass through the inner hole of the copper sleeve and place it in the appropriate position;

[0008] 3. Connect the support plate and the compression nut (M8 nut);

[0009] 4. Rotate the compression nut, and insert the tail end of the top-open sleeve into the tapered hole of the head of the split-type expansion sleeve, so that the split-type expansion sleeve expands and the tail is stuck in the bottom of the copper sleeve;

[0010] 5. Rotate the compression nut at a constant speed to slowly pull out the copper sleeve.

[0011] The utility model has a reasonable structure, realizes taking out the copper sleeve without damaging the base, reduces the labor intensity of workers, improves product quality and improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The utility model will be further described below in conjunction with the accompanying drawings. Figure 1 It is a cross-sectional structural schematic diagram of the utility model.

DETAILED DESCRIPTION

[0013] A split-type inlay sleeve extractor, such as Figure 1 , Figure 2 , Figure 3 As shown, a copper sleeve 2 is installed in an interference fit in an axial hole set on the top surface of a base 1, two symmetrical screw holes are set on the top surface of the base 1 located on both sides of the copper sleeve 2, stud bolts 3 are installed in the screw holes, a support plate 4 is provided with a center hole and symmetrical through holes, the two stud bolts 3 are matched through the symmetrical through holes of the support plate 4, and the support nut 5 installed by the stud bolt 3 is limited, and a tension bolt 6 with a hexagonal head facing downward is matched with a gasket 7, a split expansion sleeve 8, a top opening sleeve 9 with a conical end at the lower end, and a press-open nut 10. The structure of the split expansion sleeve 8 is that a disc stop is set at the lower end of the expansion tube, and an inverted cone end hole is set at the upper end of the expansion tube. The expansion tube is split along its axis and divided into two halves. The conical end of the top opening sleeve 9 matches the inverted cone end hole of the split expansion sleeve 8. The upper end of the tension bolt 6 passes through the center hole of the support plate 4, and the installed clamping nut 11 matches the support plate 4. The assembly installed by the tension bolt 6 is installed from the inner hole of the copper sleeve 2. The bottom surface of the disc stop of the split expansion sleeve 8 is higher than the bottom step surface of the axial hole of the base 1, and the top surface of the disc stop is lower than the lower end surface of the copper sleeve 2. The outer diameter of the top opening sleeve 9 plus the wall thickness of the split expansion sleeve 8 twice is less than the inner diameter of the copper sleeve 2, and the outer diameter of the disc stop of the split expansion sleeve 8 is dynamically matched with the inner diameter of the copper sleeve 2. When taking out the copper sleeve 2, first turn the compression nut 10 to make the push-open sleeve 9 push open the split expansion sleeve 8, and the disc stop of the split expansion sleeve 8 is stuck into the bottom surface of the copper sleeve 2, and then turn the compression nut 11 to drive the disc stop of the split expansion sleeve 8 through the hexagonal head of the tension bolt 6 to pull out the copper sleeve 2.
