Lamp holder of photon therapeutic instrument

The utility model belongs to the technical field of photon treatment equipment. The utility model provides a lamp holder of a photon therapeutic instrument. A shading head, a telescopic cover and a light source body are arranged; the light source body is arranged on one side of the telescopic cover to drive the telescopic cover to stretch out and draw back. The light source body is used for generating photons to be emitted into the telescopic cover; the front end of the telescopic cover is connected with the rear end of the shading head, photons are transmitted in the telescopic cover in the axial direction, the front end of the shading head directly emits the photons to irradiate lesion tissue, and therefore the technical effect that the lamp holder can be adjusted to stretch and retractis achieved, the irradiation distance matched with the lesion tissue can be easily obtained, and the curative effect of the lamp holder of the photon therapeutic instrument is enhanced. 本实用新型属于光子治疗设备技术领域，提供的一种光子治疗仪的灯头，通过设置遮光头
