As shown in the figures 10 and 13, the sewing machine 1 has a plurality of thread adjusters 11 , an oil cup 12 , a thread take-up lever 13 and a plurality of lead frames 14 for threading the suture 15 and the bottom stitch 16 , and a belt The feeding device 2 of the material is also disposed in front of the sewing machine 1, and a tape material such as a precision feeding elastic band is provided. When the quick-moving mechanism 3 is assembled, the removal mechanism 3 is closed as shown in the figures 2, 4, 6, 9A, 10, and 11, and the curved projection 365 of the elastic clip 36 is placed on the steering bracket. The underside of the steel ball 326 of 32 (as shown in Figs. 8 and 9A), the spring clip 36 and the steel ball 326 fix the base bracket 31 and the steering bracket 32, and the positioning post 323 of the rotating bracket 32 is locked to the base bracket. The notch 315 of the 31 is used as an abutting surface to be positioned with the upper base bracket 31 so as not to be arbitrarily moved when closed. At this time, the magnet of the actuating member 329 is located at the Hall integrated circuit component of the switching element 399 ( Below HALL IC), the Hall-integrated magnetic flux of the switching element 399 is maintained at a constant value, and the strip feeding device 2 can operate normally.

Referring to FIG. 5, FIG. 7, FIG. 9B, FIG. 12 and FIG. 14, when the sewing machine 1 needs to be threaded with the suture 15 and the bottom suture 16, the user feeds the strip feeding device 2 by hand. When the steering bracket 32 is opened and the force applied by the user is greater than the elastic force of the elastic clip 36 to pull the protrusion 365, the steel ball 326 gradually leaves the curved protrusion 365 of the clip under the elastic clip 36 (as shown in FIG. 9B).

At this time, the movement of the magnet position of the actuating member 329 causes the magnetic flux to change, and when the Hall integrated circuit of the switching element 399 senses a change in the magnetic flux, the strip is immediately formed. The material feeding device 2 is stopped until the steering bracket 32 is closed again. This function prevents the user from accidentally pulling the tape feeding device 2 and the steering bracket 32 apart due to the belt feeding device 2 being operated. The danger caused.

When the strip feeding device 2 and the steering bracket 32 are pulled apart, that is, the strip feeding device 2 is removed, the strip feeding device 2 no longer shields the needle 18 of the sewing machine 1 and the bottom stitch line near the needle. The device 17 and the bottom suture lead frame 14 form an open space, so that the suture 15 and the bottom suture 16 can be easily threaded, and after the suture 15 and the bottom suture 16 are worn, the strip material is fed. The device 2 and the steering bracket 32 are closed to allow the sewing machine 1 and the tape feed device 2 to operate normally.

The base bracket 31 of the above embodiment of the present invention can be integrally formed with the bracket fixing member 33 as a fixing bracket for fixing on the sewing machine 1. The steering bracket 32 can also be integrally formed with the meandering connecting member 34 and the fixing member 35. The steering bracket is formed, and the strip feeding device 2 is fixed to the steering bracket, so that the strip feeding device 2 rotates together with the steering bracket to form the fast moving device 3, and the same effect is obtained.

The switching element 399 of the safety switch 39 of the above embodiment of the present invention may also be replaced by a micro switch, a push switch and a switch, and is fixed on the base bracket 31, and the actuating element 329 may be replaced by a stud or protrusion provided on the steering bracket 32. The safety switch 39 is formed, and when the steering bracket 32 is closed, the protrusion or the protrusion is held, the micro switch is pressed, the push switch, the switch is turned on, or the micro switch, the push switch, the switch are released when the steering bracket 32 is opened, so that The control circuit of the strip feeding device 2 is turned on or off to control the operation or stop of the strip feeding device 2, and the same safety is obtained.

The switching element 399 of the safety switch 39 of the above embodiment of the present invention may also be replaced by a proximity switch or a photoelectric switch or the like and form a safety switch 39 with a suitable actuating element 329. The control circuit of the material feeding device 2 is turned on or off to control the operation or stop of the tape feeding device 2 to obtain the same safety.

The base bracket 31, the steering bracket 32 and the bracket fixing member 33 of the above embodiment of the present invention rotate the strip feeding device 2 together with the steering bracket 32 in a horizontal direction, and constitute a rapid movement for horizontal and horizontal operations. Open the mechanism 3. However, according to the innovative concept of the strip feeding device 2 of the above embodiment of the present invention, other embodiments of the present invention can also be made into a quick-moving mechanism for vertically turning in the vertical direction or further sliding in the horizontal direction. A quick removal mechanism for the rail shifting operation or the up and down vertical rail type shifting operation (not shown) is feasible.
