Description

Technical Field

[0001] This utility model relates to the field of straight needle technology, and in particular to a straight needle with an adjustable hook. Background Technology

[0002] Magnetic winding needles are tools specifically designed for winding copper wire onto magnetic rings. In the manufacturing processes of many electronic devices, particularly for critical components like inductors and transformers, copper wire needs to be wound onto magnetic rings with specific turns and rules. Magnetic winding needles play a crucial role in this process, assisting operators in precisely and systematically winding the copper wire onto the magnetic ring, greatly optimizing the entire winding process and making it simpler and more efficient. Furthermore, copper wire windings produced using magnetic winding needles tend to be more neatly and tightly arranged, which has a significant positive impact on improving the performance and quality of components like inductors and transformers. Existing magnetic winding needles are generally vertically mounted on a device, using the device's vertical movement mechanism to hook the copper wire. However, in devices without vertical movement, current improvements involve changing the fixed angle of the magnetic ring to maintain a perpendicular position with the winding needle, but the mounting mechanism itself is usually unchanged. Therefore, improvements are needed to address the bent tip of the magnetic winding needle. Utility Model Content

A sliding groove with a trapezoidal cross-section is opened on one side of the support block 6. A button 7 is fixed to the other side of the support block 6. One side of the button 7 is placed in the installation port. The positioning plate 5 facilitates the installation of the support block 6.

A limiting groove 8 is opened on the bottom surface of the other side of the inner wall of the installation port. The limiting groove 8 is slidably connected to a limiting block 9. The limiting block 9 is fixed to one side of the bottom surface of the button 7.

[0020] In this invention, L-shaped connecting plates 11 are symmetrically arranged at both the upper and lower ends of the sliding groove. One end of the L-shaped connecting plate 11 is placed outside the sliding groove, and the other end of the L-shaped connecting plate 11 abuts against the inner wall of the sliding groove. A spring 10 is provided between the two L-shaped connecting plates 11. One end of the spring 10 is fixedly connected to the support block 6, and the other end of the spring 10 is fixedly connected to the inner wall of the sliding groove. The limiting block 9 facilitates the control of the movement distance of the button 7. The L-shaped connecting plates 11 facilitate the connection of the L-shaped limiting rod 12. The spring 10 facilitates the reset of the button 7. The L-shaped connecting plates 11 are rotatably connected to the mounting port, and L-shaped limiting rods 12 are symmetrically fixed to one end of each of the two L-shaped connecting plates 11. One end of the L-shaped limiting rod 12 has a trapezoidal cross-section, and a connecting platform 13 is provided between the two L-shaped limiting rods 12.

The L-shaped connecting plate 11 rotates and connects in the mounting groove, thereby controlling one end of the L-shaped connecting plate 11 to tilt outward, thereby controlling the L-shaped limiting rod 12 to tilt outward, thereby controlling one end of the L-shaped limiting rod 12 to disengage from the fixed position. The positioning groove 14 releases the L-shaped limiting rod 12 from limiting the connecting platform 13. Then, the needle 3 is rotated, and the connecting platform 13 and the needle 3 are connected through the connecting rod 15, thereby controlling the rotation of the connecting platform 13. After the angle is adjusted, the button 7 is released, and the button 7 is pushed back by the spring 10, so that one end of the L-shaped limiting rod 12 moves inward and enters the positioning groove 14, thereby re-limiting the connecting platform 13 and limiting the angle of the needle 3. Then, the main body 1 is installed on the device through the spline shaft 2.
