In same horizontal line.
Valuably, the groove width of the via hole 210 surmount or equal to the jack 110 groove width, thus in the adjustable shelf
Allow tone frequency channel wire to be inserted into the loose slot 100 and receive column 32 with the signal when activity to lowermost end to cooperate.
When original state, the adjustable shelf is located at 100 upper end of loose slot, the beginning vertical court of the slot 31 that is connected
Under, and abutted with the piece 201 that is tamping, at this point, the via hole 210 is located at 110 upper end of jack, thus the right lever arm
21 block the jack 110；
When needing using loudspeaker, start the electricity favourable turn 40, the electricity favourable turn 40 drive the moving screws 41 into
Row operating, so that the screw thread socket 42 is driven to move downward, and the screw thread socket 42 drives the adjustable shelf movable downward,
Simultaneously as the ratcheting item 220 and the teeth section 300 are mutually ratcheting, therefore, the left lever arm 22 can drive the circle
Wiring rotary head 30 counterclockwise operates, and when the adjustable shelf activity to 100 bottom of loose slot, stops the electricity and turns
Machine 40, at this point, described be connected the operating of slot 31 extremely and in 110 same horizontal line of jack, and the via hole 210 connects the phase
Join slot 31 and the jack 110, thus allow tone frequency channel wire be inserted into it is described be connected in slot 31 and with the institute being connected in slot 31
It states signal and receives the engagement of column 32, to convey audio signal for loudspeaker；After use, tone frequency channel wire is extracted, the electricity is restarted
Favourable turn 40, the 40 driving adjustable shelf of electricity favourable turn is movable upwards, and the left lever arm 22 drives the round wiring to turn
First 30 operate clockwise, when the adjustable shelf activity to described 100 the top of loose slot, the beginning of the slot 31 that is connected
Downwards, and with the piece 201 that is tamping it abuts, and the via hole 210 is located at 110 upper end of jack, thus the right work
Swing arm 21 again blocks the jack 110.
The beneficial effects of the present invention are: adjustable shelf is located at loose slot upper end when due to original state, via hole is located on jack
End, so that right lever arm blocks jack, can prevent the particulate matters such as dust from entering in loose slot, can effectively protect and be connected
Slot and signal receive column, and the beginning for the slot that is connected at this time is downwards, and abuts with piece is tamping, so as to further to being connected
Slot and signal receive column and are protected；Since the interval of via hole to joint arm bottom wall is equal to jack between activity groove bottom wall
Every, and the difference of length of the length of loose slot in a longitudinal direction in adjustable shelf in a longitudinal direction is equal to outside round wiring rotary head
The a quarter of perimeter is turn 90 degrees to be able to drive round wiring rotary head when adjustable shelf activity to lowermost end and transport counterclockwise, and
The slot that makes to be connected is located in same horizontal line with via hole and jack, and external tone frequency channel wire can be made to be inserted into and be connected in slot and connect with signal
Column is received to be engaged；When carrying loudspeaker after removing tone frequency channel wire, electricity favourable turn drives adjustable shelf movable upwards, can make the slot that is connected
It returns to original state；Apparatus of the present invention structure is simple, easy to use, stable, without manual operation, the degree of automation
It is high.
The above, the specific embodiment only invented, but invent protection scope be not limited thereto, it is any without
The change or replacement that creative work is expected are crossed, should all be covered within the protection scope of invention.Therefore, the protection scope of invention
It should be determined by the scope of protection defined in the claims.
