Abstract
A focusing module for long focal length telescope is disclosed. The focusing module comprises a sliding plate, a fixing sleeve, and a fixing blot. The drawtube is disposed on the sliding plate for sliding forward or backward to focus. The fixing sleeve and the fixing blot form a connecting mechanism. When screwing the fixing sleeve to clamp the sliding plate from the bottom, the fixing bolt will be driven to clamp the sliding plate from the top simultaneously. This prevents the main tube and the drawtube from being displaced, and the target can be kept in the field of view of the telescope.
