Positioning structure for holding two parallel lenses of endoscope relative to each other

A positioning structure for holding two parallel lenses of an endoscope relative to each other, comprising:

• a separating-positioning component having a predetermined height in a vertical direction, with a first lens module fixed on a right side thereof, an upright abutting wall defined on a left side thereof, clamping walls extending leftward from a front end and rear end of the abutting wall respectively so as to face each other and be upright, and a slot formed jointly by the abutting wall and the two clamping walls;
• and
• a second lens module being in shape of an upright rectangular column with a rectangular cross-section, having an end abutting against the abutting wall, being parallel to the first lens module, being constrained by the two clamping walls and thus being unable to move forward and backward relative to the separating-positioning component,
• wherein the second lens module is fixed to the separating-positioning component, allowing the first lens module and the second lens module to be positioned relative to each other using the separating-positioning component.
