The heat dissipation hole 5 facilitates effective heat dissipation of the top of the driving coil 6. The lower ends of the left and right sides of the frame 1 are symmetrically provided with heat dissipation holes 12 connected to the left and right corresponding to the driving coil 6. The heat dissipation holes 12 facilitate effective heat dissipation of the side of the driving coil 6. The outer side of the fixing plate 13 is linearly arranged with heat dissipation holes 14 corresponding to the driving coil 6 and the heat sink 8. The heat dissipation holes 14 symmetrically connected to the left and right can facilitate heat dissipation of the bottom end of the driving coil 6 and the whole, and the air convection of the two heat dissipation holes 14 on the left and right can further improve the heat dissipation efficiency.

[0021] Specifically, the blade cover 3, the control panel 11 and the fixing plate 13 can be fixedly connected to the frame 1, and the soft coil pressing sheet 10 and the heat dissipation fixing beam 7 can be fixedly connected by fixing bolts and threaded holes. The principle is an existing mature technology and will not be described in detail here.

[0022] Further, such as Figure 5 and 6 As shown, it also includes an auxiliary support and fixing assembly 9, which includes a telescopic rod 91, a spring 92, a movable plate 93, an insert block 94 and a socket 95.

In addition, the elastic resistance and pressing of the soft coil pressing sheet 10 on the bottom end of the driving coil 6 to fix the position is conducive to naturally and accurately limiting the height of the driving coil 6 of the needle selector, which well meets the use requirements.

[0028] In addition, the movable plate 93 is pulled toward the heat sink 8 by the pull ring 96, which squeezes the spring 92 and drives the spring 92 of the telescopic rod 91 to contract, so that the plug block 94 is separated from the socket 95, making it easy to disassemble and maintain the heat sink 8. The reverse operation makes it easy to install, support and fix the heat sink 8.
