The right end of the output shaft of the driving motor 3 is fixedly connected to an impeller 4. A wiring terminal 5 is fixedly connected to the rear opening of the driver housing 1. A plurality of fixed plates 6 are provided, and the fixed plates 6 are respectively fixedly connected to the four corners inside the right side of the driver housing 1.

[0015] Among them, a new type of stepper motor micro-stepping driver further includes an anti-loss and easily detachable shell cover structure 7, and the anti-loss and easily detachable shell cover structure 7 is placed on the right side of the driver housing 1. The micro-stepping control circuit board 8 is fixedly connected to the middle position of the left part of the anti-loss and easily detachable shell cover structure 7, and the micro-stepping control circuit board 8 is electrically connected to the wiring terminal 5, which is conducive to achieving the effect of manual disassembly, enabling disassembly without the use of external tools and being more convenient to use.

[0016] In this embodiment, in combination with the Figure 2As shown in the figure, the anti-loss and easily detachable shell cover structure 7 includes a shell cover 71; at the openings at the four corners inside the shell cover 71, hand-tightening bolts 72 are respectively inserted; on the right sides of the hand-tightening bolts 72, first connecting rings 73 are respectively fixedly connected; one end of an anti-loss rope 74 is respectively tied inside each of the first connecting rings 73, and the other end of the anti-loss rope 74 is respectively tied to a second connecting ring 75; the left sides of the second connecting rings 75 are respectively fixedly connected to the surrounding parts in the middle of the right part of the shell cover 71; ventilation net plates 76 are respectively fixedly connected to the openings on the upper and lower sides inside the shell cover 71. When performing maintenance or regular maintenance on the present utility model, the operator can sequentially rotate the hand-tightening bolts 72 to separate the hand-tightening bolts 72 from the fixing plate 6, and then the shell cover 71 can be removed. During the removal process, no special tools are required, and only by rotating the hand-tightening bolts 72 by hand, the effect of manual disassembly can be achieved, which is more convenient to use.

[0017] In this embodiment, specifically, the shell cover 71 is placed on the right part of the driver housing 1.
