Focusing knob further includes turntable and provides the motor of power to turntable, is equipped between the turntable and knob for adjusting turntable
The elastic parts of pressure size between knob, the motor are fixedly connected by holder with turntable.
As a further improvement of the above technical scheme：
The elastic parts includes steel ball and the shell for fixing steel ball, and spring, and bullet are equipped between the shell and steel ball
Spring can make the partial denudation of steel ball in hull outside in a free state, and the knob is equipped with eccentric orfice, and eccentric orfice
Notch is sized to be slightly smaller than the exposed part of steel ball.
The shell includes that the holding being sheathed on the outside of the steel ball covers and be fixed on the compressing member for keeping set end,
The spring, which is set to, keeps set internal and between steel ball and compressing member.
The turntable is equipped with connecting shaft, and the connecting shaft is equipped with the axis hole being connected with the shaft of motor, the branch
Frame is equipped with the trepanning for installing connecting shaft, and the turntable is fixedly connected by screw with holder.
The steel ball keeps the distance for being set to center of turntable line equal at a distance from the center line of eccentric orfice to knob.
As shown from the above technical solution, when the present invention solves microscope up and down adjustment by the size of adjustment spring pretightning force
Retentivity is insufficient or excessive unstability.When microscope does automatic detection or remote detection, when retentivity deficiency, can cause
Microscope defocus, and retentivity is excessive, may result in and breaks camera lens.The present invention improves microscopy work stability and work
Make efficiency, and protects micro- lens head.

Fig. 2 is the partial enlargement exploded view of the present invention；
Fig. 3 is the partial enlarged view of Fig. 2 of the present invention；
Structural schematic diagram when Fig. 4 is the elastic parts cooperation installation of the present invention.
Specific implementation mode
The present invention will be further described below in conjunction with the accompanying drawings：
As shown in Figure 1, the microscope automatic focusing mechanism of the present embodiment, including microscope mounting bracket 1, objective table 2 and microscope
Camera lens 3, objective table 2 are set to the lower end of microscope mounting bracket 1, and mask plate 21 is equipped on objective table 2, and micro- lens head 3 is set
It is placed in the upper end of microscope mounting bracket 1 and the surface positioned at mask plate 21, the lower section of objective table 2 is equipped with pallet 4, on pallet 4
Equipped with focusing knob 41, further includes turntable 5 and the motor 6 of power is provided to turntable 5, be equipped with and be used between turntable 5 and knob 41
The elastic parts of pressure size between turntable 5 and knob 41 is adjusted, motor 6 is fixedly connected by holder 7 with turntable 5.
As shown in Fig. 2, the elastic parts of the present embodiment includes steel ball 81 and the shell 82 for fixing steel ball 81, in shell
Spring 83 is equipped between 82 and steel ball 81, and the spring 83 can make the partial denudation of steel ball 81 in shell 82 in a free state
Outside, knob 41 are equipped with eccentric orfice 42, and the notch of the eccentric orfice 42 is sized to be slightly smaller than the exposed part of steel ball 81, so that steel ball
81 be mounted on eccentric orfice 42 in when, between knob and shell 82 have certain gap, to make turntable 5 not with focusing knob
41 contacts.The steel ball keeps set 811 to arrive phase at a distance from the center line of knob 41 to distance and the eccentric orfice 42 of 4 center line of turntable
Deng.
As shown in Figure 3,4, which includes being sheathed on the holding set 811 in 81 outside of steel ball and being fixed on holding to cover 811
The compressing member 822 of end, spring 83, which is set to, to be kept inside set 811 and between steel ball 81 and compressing member 822, on turntable 5
Equipped with the mounting hole 43 to match with holding 811 sizes of set.
As shown in figure 3, being equipped with connecting shaft 51 on turntable 5, which, which is equipped with, is connected with the shaft of motor 6
Axis hole 52, is equipped with the trepanning 71 for installing connecting shaft 51 on holder 7, which is fixedly connected by screw with holder 7.
The pretightning force that spring 83 is applied on steel ball 81 is controlled by the depth of the screw-in of compressing member 822, steel ball 81 reveals
Go out in the eccentric orfice 42 being partially placed on knob 41 that steel ball keeps outside set 811, steel ball 81 is contacted with 42 surrounding of eccentric orfice.
When motor rotates, knob 41 is imparted power to by steel ball 81 and knob 41 is driven to rotate, realizes focus function.And pass through
The size for adjusting pretightning force, can improve microscopical retentivity；Equally, by adjusting the size of pretightning force, can to work as
When wafer or mask plate 21 encounter micro- lens head 3, when extruding force is more than certain value, the steel ball 81 under motor 6 drives is pushed back
It being kept in set 811 to steel ball, steel ball 811 starts in 41 surface scrolls of knob, and extruding force reduces, and ensures that camera lens 3 is not damaged,
It skids before breaking micro- lens head 3, to protect micro- lens head 3.
