The manual tapping assembly 5 also includes a rotating handle 504, which is fixed above the threaded rod 503, and the bottom of the threaded rod 503 is fixedly connected to the connecting rod 6. The electric telescopic rod 4 is extended and retracted to facilitate adjustment of the front and rear positions of the manual tapping assembly 5, the connecting rod 6, the mounting block 10, and the tapping head 13, so as to adjust the tapping position. The rotating handle 504 is rotated to facilitate rotation of the threaded rod 503 within the threaded barrel 502, thereby driving the connecting rod 6, the mounting block 10, and the tapping head 13 below the threaded rod 503 to rotate and move downward, thereby achieving manual tapping.

[0021] like Figure 1-Figure 2As shown, the manual tapping assembly 5 is connected to a connecting rod 6 at the bottom, and a disassembly assembly 9 is installed on the outside of the connecting rod 6. The disassembly assembly 9 includes a fixed frame 901, a micro linear motor 902, a connecting rod 903 and a positioning insert 904. The fixed frame 901 is fixedly connected to the connecting rod 6. The micro linear motor 902 is slidably installed at the bottom of the fixed frame 901, and the micro linear motor 902 is connected to the connecting rod 903 at the bottom. A positioning insert 904 is fixed to the bottom of the connecting rod 903, and three positioning inserts 904 and three fixed frames 901 are provided. A mounting block 10 is installed at the bottom of the connecting rod 6, and the outer side of the mounting block 10 is opened. There are three positioning holes 11, and a tapping head 13 is fixed to the bottom of the mounting block 10; the mounting block 10 and the tapping head 13 are located below the connecting rod 6, so that the three positioning holes 11 correspond one to one with the positions of the three positioning inserts 904. The movement of the micro linear motor 902 in the fixed frame 901 facilitates the movement of the connecting rod 903 and the positioning insert 904, so that the three positioning inserts 904 can be inserted into the inside of the three positioning holes 11, realizing the assembly between the connecting rod 6 and the mounting block 10, and then realizing the installation of the tapping head 13. This connection method does not require the use of bolts and can facilitate the disassembly, assembly and replacement of the mounting block 10 and the tapping head 13.

During the installation process, the ring-shaped rotary joint 12 is located on the outside of the limiting ring 8. The rotary joint 12 is adapted to the outer sleeve 7. Therefore, moving down and rotating the outer sleeve 7 can threadably connect the rotary joint 12, thereby further improving the installation stability of the mounting block 10. The electric push rod 15 is convenient for telescopic adjustment of the position of the positioning plate 16 so that the two positioning plates 16 can position the workpiece.

[0023] In summary, if Figure 1-Figure 3As shown, the manual tapping machine with the tapping head that is easy to disassemble and assemble, when in use, first, the workpiece can be placed on the base plate 1, and then the position of the positioning plate 16 can be adjusted by the electric push rod 15 so that the two positioning plates 16 can position the workpiece, and then the front and rear positions of the manual tapping assembly 5, the connecting rod 6, the mounting block 10, and the tapping head 13 can be adjusted by the extension and contraction of the electric telescopic rod 4. When tapping, the rotation of the handle 504 drives the rotation of the threaded rod 503 inside the threaded barrel 502, so as to drive the rotation and downward movement of the connecting rod 6, the mounting block 10, and the tapping head 13 below the threaded rod 503, thereby realizing manual tapping;

[0024] When the tapping head 13 needs to be replaced, the outer sleeve 7 can be rotated to unscrew it, and then away from the three positioning inserts 904, and then a new tapping head 13 can be replaced so that it is located below the connecting rod 6, and the three positioning holes 11 are made to correspond one to one with the positions of the three positioning inserts 904, and then the movement of the micro linear motor 902 in the fixed frame 901 drives the movement of the connecting rod 903 and the positioning inserts 904, so that the three positioning inserts 904 are snapped into the inside of the three positioning holes 11 to realize the assembly between the connecting rod 6 and the mounting block 10, and then the installation of the tapping head 13 is realized. During the installation process, the ring-shaped rotary joint 12 is located on the outside of the limit ring 8, and the rotary joint 12 is adapted to the outer sleeve 7, so the outer sleeve 7 can be moved down so that it is located on the outside of the rotary joint 12, and then the outer sleeve 7 is rotated to thread the rotary joint 12, thereby further improving the installation stability of the mounting block 10, and thus completing the use process of the manual tapping machine with easy disassembly and assembly of the tapping head.
