Firmly-fixed LED (light-emitting diode)

The utility model discloses a firmly fixed LED (light-emitting diode), which belongs to the technical field of LEDs, aims at solving the problem that pins are easy to break due to unstable connection when the LED is used, and comprises mounting rods which are respectively fixed at the front and rear parts of the left and right sides of the top wall of a mounting plate. Sliding grooves are formed in the middles of the opposite side walls of the front and rear mounting rods, sliding blocks are slidably connected to the inner sides of the sliding grooves, and the sliding blocks are fixed to the middles of the front and rear side walls of the connecting plates correspondingly; according to the utility model, the pins are respectively inserted into the clamping grooves and then the screws at the two sides are rotated, the screws drive the two groups of arc-shaped clamping plates to get close to each other in the rotation process, the diode main body is clamped and fixed through the arc-shaped clamping plates, and
