Display screen load bearing seat 120 has a variety of relative position relations.Furthermore, when the driving display screen load bearing seat 120 of knob 102 moves
When dynamic, the first guide groove O1 and the second guide groove O2 of closing can respectively as the first projection 152B and the second projection 154B track,
And then the moving range of display screen load bearing seat 120 is defined, or prevent display screen load bearing seat 120 even to be held because being moved through with lens
Seat 110 is carried to depart from.On the other hand, the moving range of display screen load bearing seat 120 can be defined as 2 centimetres to 4 centimetres.Second securing cover plate
158A, 158B, 158C and 158D can be respectively arranged at four corners of lens load bearing seat 110, its can as the cover plate of each guide rod,
To prevent each guide rod from being come off from lens load bearing seat 110.
Please see that Fig. 5, wherein Fig. 5 are illustrated in the wear-type device 100B according to second embodiment of the present utility model again
It is driven the configuration schematic diagram of configuration mode.At least one discrepancy of present embodiment and first embodiment is transmission module
130 the first tooth sector 146A and 146B gear teeth is face each other, and the second tooth sector 148A and 148B gear teeth
To face each other.In other words, the first tooth sector 146A and 146B and the second tooth sector 148A of transmission module 130 and
The position that 148B is configured can change so that the size design of lens load bearing seat 110 can be more flexible, is worn with adjustment
Size length-width ratio overall formula device 100B.On the other hand, second securing cover plate 158A, 158B, 158C and 158D setting
There is selectivity in response to the size of lens load bearing seat 110, for example, in some embodiments, the second securing cover plate
158C and 158D can be omitted.
In summary, wear-type device can be by turning knob and the transmission module of connection, and driving display screen load bearing seat
Carry out the movement closer or far from lens load bearing seat.Therefore, wearer can easily pass through turning knob and just adjust the condition of viewing and admiring,
And then obtain and good view and admire experience.Further, since the first drive gear is mutually symmetrical with lens load bearing seat, and the second sliding tooth
Wheel is also mutually symmetrical with lens load bearing seat, therefore display screen load bearing seat can smoothly carry out the shifting close to or away from lens load bearing seat
It is dynamic, with avoid because dislocation and caused by component it is stuck.
For above-described embodiment only to illustrate technical concepts and features of the present utility model, its object is to allow be familiar with technique
Personage can understand content of the present utility model and implement according to this, the scope of protection of the utility model can not be limited with this.
All equivalent change or modifications made according to the utility model Spirit Essence, should all cover the scope of protection of the utility model it
It is interior.
