One end of part 733 constantly can slide into another adjacent groove 7321 from a groove 7321, wherein slide into other one
After a groove 7321, under the action of the elastic restoring force of elastic component 733, the bottom of the groove 7321 can automatically with elastic component
733 position is corresponding, in this way so that user can rapidly and accurately adjust face-piece 720 and main casing 710 arrives scheduled position
State, without repeatedly adjusting the position between face-piece 720 and main casing 710.In addition, in adjustment process, by elasticity
One end of part 733 constantly can slide into another adjacent groove 7321 from a groove 7321, can opposite in adjustment process
Shell 720 brings seismaesthesia, is convenient for user's visual perception internal structure working order.
Please refer to Fig. 1, Fig. 2 and Fig. 4, in embodiments of the present invention, projecting apparatus further includes that connector group (is not shown in figure
Go out), connector group includes power connector, USB connector and HDMI connector.Pass through USB connector and HDMI connections
Device is realized to establish with other electronic equipments and be connected, and is realized and is played simultaneously and shares the video in electronic equipment, word, image etc..
One end of power connector is electrically connected with power module, and the other end is by 701 chamber of accommodating chamber of main casing 710
Wall stretches out.One end of USB connector and one end of HDMI connector are connect with main control chip 300, and the other end is by main casing
710 701 cavity wall of accommodating chamber is stretched out.Face-piece 720 when face-piece 720 is in projection state the interface of exposed power connector,
The interface of USB connector and the interface of HDMI connector, and block power connector when face-piece 720 is in occlusion state
Interface, the interface of USB connector and the interface of HDMI connector.Based on this structure design, thrown when needing to use
When shadow instrument, tune connector group is exposed outside, establishes and connects with other electronic equipments convenient for projecting apparatus, and projecting apparatus need not be used by working as
When, face-piece 720 will also block connector group, in this way, being played a certain protective role to connector group, avoid binding dust, or by it
He bumps to foreign object.
In the present embodiment, connector group further includes power switch, and one end and the power module contact of power switch connect
It connects, the other end is stretched out from the cavity wall of accommodating chamber 701.Power switch is for switching 300 circuit of main control chip, i.e., when needs make
It when with projecting apparatus, touches and presses power switch, power module is made to power for main control chip 300；When do not need in use, again touch by electricity
