[0045] Specifically, by rotating the rotary sleeve 4, the boss 22 is driven to rotate, and then the adjusting device 5, the top shaft 11 and the fixing rod 14 are rotated. When the adjusting device 5 rotates, the protrusion 56 and the slider 7 move relative to each other. When the slider 7 and the magnetic block 57 are fixed by magnetic attraction, the telescopic rod 15 moves downward, stretching the compression spring 9, and fixing the telescopic rod 15 through the limit ring 8. The rotation of the adjusting device 5 makes the magnetic block 57 and the slider 7 no longer fixed, and the tension of the compression spring 9 is released, pushing the telescopic rod 15 upward, so that the slider 7 is inclined along the two sides of the protrusion 56.

[0046] A plurality of positioning holes 13 are formed on the upper surface of the upper housing 1 .
[0047] Specifically, the upper shell 1 completes the installation of the angle head through the positioning hole 13.
[0048] During use, by rotating the rotary sleeve 4, the boss 22 is driven to rotate, and then the adjusting device 5, the top shaft 11 and the fixing rod 14 are rotated. When the adjusting device 5 rotates, the protrusion 56 and the slider 7 move relative to each other. When the slider 7 is fixed by the magnetic attraction of the magnetic block 57, the telescopic rod 15 moves downward, and the compression spring 9 generates a pulling force to push the telescopic rod 15 upward, so that the slider 7 quickly moves along the inclined surfaces on both sides of the protrusion 56 to the slideway 55, and the orthogonal spiral bevel driven gear 12 and the orthogonal spiral bevel driving gear 21 of a tool are rotated. 2 is released from meshing, and the adjusting device 5 continues to rotate to make the slider 7 continue to move along the slideway 55, and then the slider 7 moves along the inclined surface of the protrusion 56 toward the magnetic block 57 at the bottom of the protrusion 56, and the compression spring 9 is continuously stretched to generate a pulling force. After the slider 7 and the magnetic block 57 are magnetically fixed again, the orthogonal spiral bevel driven gear 12 and the orthogonal spiral bevel driving gear 212 of another tool are meshed. The completion of the tool change can be determined by the change of elastic force felt when the rotary sleeve 4 is manually rotated and the sound generated after the magnetic fixation.
