[0043] The principle behind the horizontal adjustment of the display screen is as follows:

[0044] The display screen mounting frame 19 of the scope is pressed onto the nut 17 by the display component fixing spring. Since the inner diameter of the through hole through which the screw 16 passes on the display screen mounting frame is larger than the outer diameter of the screw 16, there is a certain amount of relative movement between the screw 16 and the display screen mounting frame 19. When it is necessary to adjust the display screen 9 horizontally, the adjusting screw 20 is rotated to change the amount of insertion of the adjusting screw 20 inside the rear scope body 2. As a result, the adjusting screw 20 pushes against the display screen mounting frame 19 and moves it horizontally. During the movement, the display component adjusting spring provides horizontal elastic force.

[0045] The locking principle between the battery tube and the battery compartment is as follows:

[0046] Before inserting the battery tube into the battery compartment, the operator closes the operating button 25 to the center and holds it in this position. At this time, the positioning pin 23 also moves towards the center, and simultaneously, the battery removal spring is compressed, causing the outer end of the positioning pin 23 to retract into the pin hole, allowing the battery tube to be inserted into the battery compartment. Then, the operator releases the operating button 25, and the positioning pin 23 moves outward under the elastic force of the battery removal spring, thus inserting the outer end of the positioning pin into the locking hole of the battery compartment, completing the locking. Similarly, to unlock the battery tube from the battery compartment, simply close the operating button and pull out the battery tube.

[0047] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
