The component mounting hole 132 is adjacent to the top of the support member 30 , and the electrical component 50 is mounted on the component mounting hole 132 and is exposed on the bottom surface of the bottom case 13 . The component mounting holes 132 in this embodiment are formed on the mounting seat 130 . The electrical component 50 is used to connect a power cord C2. The power cord C2 passes through the hollow screw 40 on the bottom case 13, the screw channel 31 of the support 30, and the hollow screw 40 on the upper cover 23, and extends to the second slave device within 20.

Preferably, in order to increase the stability of the stacked electronic device 100 after being combined, in the embodiment of the present invention, the support member 30 retains two spaces for screwing. Therefore, the bottom case 13 of the first slave device 10 also has a second screw hole 133 and a second screw 15 , and the second screw 15 passes through the second screw hole 133 and is screwed to the support member 30 . The second screw 15 can be a general screw or the above-mentioned hollow screw as needed. The second screw 15 is used as a general screw, and the diameter of the screw rod of the second screw 15 is smaller than the diameter of the screw rod 42 of the hollow screw 40 .

One of the beneficial effects of the present invention is that the stacked electronic device 100 of the present invention utilizes the hollow screw 40 to save the space occupied by the support member 30 . As shown in FIG. 3 to FIG. 5 , after the first slave device 10 and the second slave device 20 are fixed in the multi-layer electronic device 100 of the present invention, the hollow channel 410 of the hollow screw 40 and the screw channel 31 of the support member 30 pass through. On the one hand, the screw channel 31 of the support 30 can be used for locking the hollow screw 40, and on the other hand, the wire can be passed through. That is to say, the screw channel 31 combines the dual functions of the locking hole and the threading hole. The support member 30 of the present invention is matched with the hollow screw 40, and the support member 30 does not need to have a wire hole. The support member 30 can reduce one hole position without increasing the volume of the support member, so as to achieve fixation and functionality, and can meet the appearance design requirements of the small volume of the product.

In this embodiment, in order to facilitate the positioning and assembly of the support member 30 to the second slave device 20 , an engagement hole 230 and a positioning protrusion 231 are formed on the upper cover 23 of the second slave device 20 . The positioning protrusion 231 extends toward the engaging hole 230 , and a plug portion 32 protrudes from the bottom end of the support member 30 . Specifically, the engaging hole 230 of the upper cover 23 is slightly U-shaped, the insertion portion 32 of the support member 30 is bifurcated to form an open slot 320 , and the insertion portion 32 is inserted into the outer periphery of the positioning convex portion 231 . space. The open slot 320 of the plug-in portion 32 of the support member 30 can be used as a light-transmitting hole for the electrical component 50 of the LED indicator on the one hand, and can be used for fixedly locking the second screw 15 on the other hand.

In other words, the support member 30 of the present embodiment provides two screw fixing holes (the first screw hole 131 and the second screw hole 133 ), and a light-transmitting hole. The first screw hole 131 can also be used as a threading hole.
