[0023] Specifically, Figure 1 and Figure 2 As shown, when in use, the metal platform 8 at the side end of the connecting plate 7 can be inserted into the slot 9 at the side end of the locator 11 and adsorbed by the magnet 10 inside the slot 9. Conversely, after the metal platform 8 is separated from the slot 9, the locator 11 can be removed and used alone;

[0024] The interior of the locator 11 is provided with a mounting groove 12, and a laser 13 is installed inside the mounting groove 12. An adjusting platform 14 is fixed on the surface of the connecting platform 4. Two groups of adjusting platforms 14 are fixed on the surface of the connecting platform 4, and the two groups of adjusting platforms 14 are symmetrically distributed. An adjusting bolt 15 is provided inside the adjusting platform 14, and an internal thread is provided inside the adjusting platform 14. The surface of the adjusting bolt 15 is provided with an external thread. The adjusting platform 14 and the adjusting bolt 15 are connected through threads. An adjusting knob 16 is fixed at the bottom end of the adjusting bolt 15, and a first positioning platform 17 is fixed at the center position of the top end of the adjusting knob 16. A spring 18 is provided on the outside of the first positioning platform 17, and a pressure block 20 is provided at the top end of the spring 18.

[0028] Working principle: When in use, tear off the release paper 25 on the surface of the foam tape 24 on the back of the base 1, and use the foam tape 24 to bond the base 1 to the sewing machine for use. The laser 13 on the side end points to the needle tip processing position. When adjustment is required, manually turn the locator 11 to adjust the irradiation position of the laser 13 until the irradiation position is located at the needle tip processing position. If the friction between the ball core 6 and the connecting groove 5 is small, when the locator 11 is loose, the adjustment bolt 15 on the surface of the connecting platform 4 can be rotated, and the adjustment bolt 15 presses the inner The spring 18 on the side can apply pressure to the pressure block 20, and the pressure block 20 cooperates with the friction plate 21 to press on the surface of the ball core 6, which can help increase the friction between the ball core 6 and the connecting groove 5. The metal table 8 at the side end of the connecting plate 7 is adsorbed and connected with the magnet 10 at the side end of the locator 11. In this way, after the metal table 8 is separated from the slot 9, the locator 11 can be removed. At this time, if the processing table is made of iron, the locator 11 can be adsorbed on the table surface, and the emitted light can be used to assist in guiding the sewn line.
