Graduation rebound, for fastening the graticle.
Further, the graduation rebound is circular ring structure, and the graduation rebound width is wide more than the graticle
Degree, the graduation rebound is correspondingly arranged on pin hole up and down, for being driven the graticle, the graduation rebound top institute
State 45 ° of the pin hole left and right sides and be additionally provided with pilot hole.
Further, on the guide cylinder under be correspondingly arranged on two straight troughs along axis, be respectively arranged with the straight trough
3rd pin, the 3rd pin is connected through the pin hole with the graticle, straight trough two described in the guide cylinder top
45 ° of side is also provided with gathering sill, and guide pin is provided with the gathering sill, and the guide pin runs through the pilot hole and the graduation
Plate is connected.
Further, the guide cylinder and lens spiral-tube are terraced structure, including leading portion and back segment, the guide cylinder
Leading portion is provided with leading portion straight trough along axis, and back segment is provided with two back segment straight troughs, the graduation spiral-tube along axis is symmetrical above and below
The back segment of the lens spiral-tube is arranged on, two graduation zoom curved grooves are correspondingly arranged on the graduation spiral-tube, it is described
Lens spiral-tube leading portion is provided with a first zoom curved groove, and back segment is provided with a second zoom curved groove, the lens
Two the 3rd zoom curved grooves are additionally provided with spiral-tube back segment two graduation zoom curved grooves of correspondence.
Further, the first pin is provided with first lens, first pin extends through described first and becomes
Times curved groove and the leading portion straight trough are connected with first lens, and the second pin, described are provided with second lens
Two pins extend through the second zoom curved groove, a back segment straight trough and are connected with second lens.
Further, the graticle is vertically disposed with two the 3rd pins, and the 3rd pin extends through described point
A wipe times curved groove, the 3rd zoom curved groove, back segment straight trough, graduation rebound is connected with the graticle.

The differentiation rebound set between cylinder makes the graduation frame in guide cylinder be linked into an integrated entity with the differentiation rebound outside guide cylinder, will divide
Diameter and the thickness for drawing plate break up the diameter of rebound than marrying again with thickness than upper, because graduation rebound avoids optical lens
Mirror extrudes space, and the thickness for breaking up rebound can be increased, so that the overall structure of graticle reduces diameter and thickness ratio, solution
The problem of graticle force unbalance of having determined, it is to avoid it is motionless that graticle inclines clamping stagnation.
Further, because graduation board space is extruded in low power by lens position, graduation sheet frame can only be made thin thin, nothing
Method reaches the smooth state that lens movement is consistent during with zoom, in addition graduation sheet frame due to force unbalance cannot be in guide cylinder
Mobile, the application is driven to improve force unbalance problem using two into 180 ° of symmetrical pins, in transmission nail left and right
Both sides are at 45 ° to set graduation guide pin, and being driven two, plus side face guide pin by two upper and lower pins of graticle is oriented to jointly
Ensure that graticle is not inclined.
Further, because graduation spiral-tube is enclosed within lens spiral-tube, handwheel passes through graduation spiral-tube by start
Passing on graticle needs to penetrate lens spiral-tube, so opposite position processes two slots to make way on lens spiral-tube, allows
Position well width realizes graduation regulatory function not less than the front and rear adjustable range of graticle.
Further, graticle is controlled using the mode of engagement and the separation of groove relative to the position of lens, advantage
It is to realize the big displacement of graticle with less handwheel start space, compact structure is simple to operate.
Further, by the optimization design to groove length and position, make between handwheel and graduation spiral-tube, handwheel with
Realize that transmission reaches regulation graticle purpose between lens spiral-tube respectively.Two-way start is all driven by one part of handwheel,
Meet portable operation requirement.
