74 connections.That is, the driving assembly that the driving turntable mainboard 70 of the utility model moves in the circumferential direction is to be axially located in turntable mainboard
On 70, shaft 71 can do length as much as possible.In the present embodiment, along axial direction, fixed 73 one end of holder assembly is solid with one of them
Determine the connection of part 72, the other end is connect with motor 74, and shaft coupling 75 is located in fixed holder assembly 73.Motor 74 works, drive shaft
71 rotations, then drive turntable mainboard 70 to move in the circumferential direction, realize the switching of the object lens 11a of different multiplying.Wherein, fixing seat group
The concrete type of part 73 with no restrictions, can support shaft 71.
With reference to Figure 16, Figure 17 and Figure 19, in the present embodiment, fixing piece 72 is two, one of fixing piece 72 with it is fixed
Holder assembly 73 is bonded, another fixing piece 72 is bonded with reference for installation plate 51.In this way, reference for installation plate 51, two is fixed
Part 72, fixed holder assembly 74 and turntable locating structure mainboard 52 form rigid connection, preferably support shaft 71, can be further
A possibility that reducing by 71 beat of shaft, and the galianconism due to being shaft 71 drives turntable mainboard 70, improves turntable mainboard 70 and exists
The stability of circumferential movement, promotes the positioning accuracy of object lens, then promotes microscopical measurement accuracy.It should be noted that fixed
Part 72 is not limited to connect with fixed holder assembly 73 and reference for installation plate 51, can play the role of fixed rotating shaft 71.
Continue to refer to figure 15 and Figure 16, turntable mainboard 70 is equipped with the first locating piece 76, and reference for installation plate 51 is equipped with the
Two locating pieces 77, when turntable mainboard 70 circumferentially turns to the object lens of a certain multiplying power, the first locating piece 76 and the second locating piece
77 cooperate, and the movement of limitation turntable mainboard 70 in the circumferential switches to the object of another multiplying power in the object lens by a certain multiplying power
When mirror, the first locating piece 76 and the separation of the second locating piece 77.For example, motor 74 works, turntable mainboard 70 is circumferentially rotated, micro-
When mirror switches to powerful object lens by the object lens of low range, the first locating piece 76 and the second locating piece 77 cooperate, and play
The effect of position objective, motor 74 stop working, and the movement of limitation turntable mainboard 70 in the circumferential, microscope can be stablized in height
The object microscopic observation sample of multiplying power;In the object lens for needing low range, motor 74 works on, at this time the first locating piece 76 and
The separation of two locating pieces 77, turntable mainboard 70 can be rotated circumferentially, and microscope is switched to the object of low range by powerful object lens
Mirror.
Specifically, one of the first locating piece 76 and the second locating piece 77 are groove, Ling Yiwei in the utility model
Bearing.In the present embodiment, with reference to Figure 16, Figure 18 and Figure 19, the first locating piece 76 is set to turntable mainboard 70 towards reference for installation plate
51 part, the first locating piece 76 are groove, and the second locating piece 77 is set to part of the reference for installation plate 51 towards turntable mainboard 70,
Second locating piece 77 is bearing, and reference for installation plate 51 is equipped with the fixed link 79 axially extended, and bearing holder (housing, cover) is set to fixed link 79.
Wherein, reference for installation plate 51 is equipped with fixed metal plate 78 towards the part of turntable mainboard 70, and fixed link 79 is installed on fixed metal plate 78
On, bearing can be rotated around fixed link 79.
When turntable mainboard 70 circumferentially turns to the object lens of a certain multiplying power, bearing is located in groove, plays position objective
Effect, motor stops working, and the movement of limitation turntable mainboard 70 in the circumferential switches to another in the object lens by a certain multiplying power
When the object lens of multiplying power, motor 74 works, and relatively rotates between bearing and groove, so that the first locating piece 76 and the second positioning
Part 77 separates, and turntable mainboard 70 can continue to move in the circumferential direction.
