The right-angle clamping groove is suitable for clamping diodes of different sizes. At the same time, a limit plate 306 is fixedly mounted on the fixing seat 301. The limit plate 306 runs through the clamping plate 304. By placing the lamp bead part of the diode between the clamp block 303 and the clamping plate 304 and abutting against the limit plate 306, and then rotating the screw 305 to push the clamping plate 304 close to the diode until it fits the diode, the diode can be fixed.
