Description

[0002] Laser ranging telescope is the instrument that utilizes laser to the distance of target accurate determination, and laser range finder emits a very thin laser to the target when working, and the laser beam of target reflection is received by photoelectric element, and the time of laser beam from emission to reception is measured by timer, and the distance from observer to target is calculated.

[0003] Torsion is the force that makes the object torsion deformation.

[0004] The eyepiece adjustment structure of the existing laser ranging telescope is all knob mechanical type, and the distance between eyepiece lens and built-in display screen needs to be changed by rotating knob.

Therefore, the torsion of knob needs to be tested to ensure that the product reaches the qualified standard. Since the existing torsion test detection process adopts manual sampling inspection mode, manual operation cannot directly measure the accurate torsion value, and also needs rich testing experience. The test efficiency is low, the efficiency of manual sampling inspection is only 20%-30% of automatic detection, cannot reach the speed of automatic production, and needs large manpower cost. Therefore, an accurate test device for testing the torsion value of laser ranging telescope eyepiece focusing knob is needed. UTILITY MODEL CONTENTS
