The connecting sleeve 27 is located between the inner wall of the rear cover 13 and the second fastener 20. When the floodlight is placed, the shell 1 is supported by the bracket 3. The first fasteners 4 at both ends of the bracket 3 can be loosened to drive the second fastener 20 along the rod of the first fastener 4 to approach the movable hole 25. At this time, the end of the bracket 3 is unlocked from the shell 1 and can be rotated to adjust the angle between the shell 1 and the bracket 3, or the floodlight is carried by holding the bracket 3. After the position between the shell 1 and the bracket 3 is adjusted, the first fasteners 4 at both ends of the bracket 3 can be tightened to drive the second fastener 20 along the rod of the first fastener 4 away from the movable hole 25. The first fastener 4 drives the connecting sleeve 27 to approach the inner wall of the rear cover 13 until the inner wall of the rear cover 13 and the opposite sides of the second fastener 20 are respectively pressed against the two sides of the connecting sleeve 27. The end of the bracket 3 is locked with the shell 1, so that the adjustment operation of the angle of the illumination direction of the floodlight is more convenient.

[0032] A hanging member 28 is rotatably mounted on the top of the rear cover 13, so that the user can suspend the floodlight in the air and use it as a hanging lamp, thereby improving the applicability of the floodlight.
