Support plate 404 and limiting assembly 405. The slide groove 401 is provided on the top surface of the base body 100. The bottom end of the rear slide plate 402 is slidably connected to the slide groove 401. The front surface of the base body 100 is connected to the front slide plate 403 through the limiting assembly 405. The support plate 404 is fixedly connected between the rear slide plate 402 and the front slide plate 403. The rear slide plate 402 can be moved to slide inside the slide groove 401, so that the support mechanism 400 can be adjusted to the left and right positions. The circuit board 300 is overlapped on the top surface of the support mechanism 400 to support the middle part of the circuit board 300.

[0021] In this embodiment, preferably, the limit assembly 405 includes a through hole 4051, a limit rod 4052 and a limit slot 4053. The through hole 4051 is opened through the bottom end of the front slide plate 403, the limit rod 4052 is slidably embedded in the through hole 4051, and the inner end is inserted into the limit slot 4053 opened on the front surface of the seat body 100, and a plurality of limit slots 4053 are opened at equal distances. A person can pull the limit rod 4052 outward to disengage it from one of the limit slots 4053. At this time, the limit of the entire support mechanism 400 is released, and the left and right position can be adjusted, and then the limit rod 4052 is inserted into the other limit slot 4053 to complete the limit fixation of the support mechanism 400.
