[0029] The rotary connection of the lamp body 2 and the base 1 can also use other forms, such as a pivot, and is not limited to Figure 2 The connecting mode of the base 1 and the outside is not limited to adhesion, but also can be connected by screws or hooks.

[0030] Figure 3is an exploded view of the lamp head 3 in the second embodiment of the present application. On the basis of the first embodiment, the lamp head 3 further comprises a focusing mechanism, which comprises an inner rotating support 361, a convex lens 362, and a focal length adjusting ring 363. The inner rotating support 361 is rotationally connected in the head housing 31. The light source assembly 34 is threadedly connected to the bottom of the inner rotating support 361. The convex lens 362 is fixed to the top of the inner rotating support 361. The focal length adjusting ring 363 is fixed to the top of the inner rotating support 361. The focal length adjusting ring 363 has a first through hole 3631 in the middle thereof, which exposes the convex lens 362.

The lamp bead 341 generates heat when illuminated, and the heat sink 345 can transfer the heat generated by the lamp bead 341 during illumination to ensure the normal operation of the lamp bead 341. The sliding connection between the radiator 345 and the rotating bracket 33 can limit the rotation of the light source cover 343. When the inner rotating bracket 361 rotates, the light source cover 343 can only move in the direction away from or close to the convex lens 362, thereby adjusting the size of the light beam illumination area.

[0034] The method of limiting the rotation of the light source housing 343 is not limited to Figure 3 The structure shown can also be achieved by providing a specific structure on the light source cover 343 to achieve a sliding connection between the light source cover 343 and the head cover 31 to limit the rotation of the light source cover 343. For example, a boss or groove that cooperates with the head shell 31 can be provided on the light source cover 343, or a slider or guide rail that cooperates with the head shell 31 can be provided on the light source circuit board 342 to limit the rotation of the light source cover 343.

[0036] The magnetic part 21 provided on the lamp body 2 is adsorbed on the magnetic attraction plate 11. Since the base 1 has a predetermined angle, a predetermined angle is formed between the lamp body 2 and the external contact surface after installation. When the lamp body 2 rotates around its central axis, it will drive the lamp head 3 to rotate, so that the range of change of the rotation angle of the lamp head 3 when it moves relative to the outside is larger, and the illumination range of the light beam is further expanded.

[0037] Furthermore, if Figure 5As shown, the magnetic plate 11 is circumferentially provided with a clamping step 111, and the first plate body 131 of the wall seat 13 is provided with a plurality of second clamping hooks 133 and an elastic clamping hook 134 on the side in contact with the magnetic plate 11, and the space between the second clamping hooks 133 and the elastic clamping hook 134 forms a space for accommodating the clamping step 111.
