[0008] By adopting the above technical solution, when the device needs to adjust the beam angle, the reciprocating body rotates, and the reciprocating body causes the adjustment track provided in the reciprocating body to rotate, so that the position of the reciprocating protrusion passing through the adjustment track changes, so that the reciprocating protrusion moves relatively along the length of the adjustment track, so that the reciprocating protrusion drives the first lens to move toward or away from the light source module, so that the convergence position of the light emitted from the light source module changes, so that the beam angle of the light emitted by the light source module changes, when the first lens is away from the light source module, the light angle of the light source module is smaller, so that the light emitted by the device is better converged, when the first lens is close to the light source module, the light angle of the light source module is larger, so that the light emitted by the device is better converged, which improves. This type of optical device generally only provides a single light beam angle, which makes it difficult to meet the demand for beam angles of different angles during use.
[0009] Optionally, the first lens is provided with a plurality of convex lenses, and the convex lenses are evenly distributed along the diameter direction of the first lens.
[0010] By adopting the above technical solution, the convex lenses are arranged so that the light emitted by the light source module is refracted independently by each convex lens, so that when the light passes through the first lens and is diffused independently by each convex lens, the light overlaps, thereby making the light emitted by the device more uniform and more usable.

When the first lens is away from the light source module, the light angle of the light source module is smaller, thereby causing the light emitted by the device to converge better. When the first lens is close to the light source module, the light angle of the light source module is larger, thereby causing the light emitted by the device to converge better, thereby improving. This type of optical device generally only provides a single light beam angle, which makes it difficult to meet the demand for beam angles of different angles during use.
