As in figure 2 it is shown, the head of bolt 241 offers cross recess.
Earmuff wear or after wear control method:
Because ear's protector has directivity, main protection part is positioned at the rear portion of ear's protector；
When wearing, limited block 2221 is positioned at the vertical portion of stopper slot 2331, when wearing after needs, it is only necessary to inwardly pin unblock
Button 221, makes limited block 2221 depart from the vertical portion of stopper slot 2331, then earmuff body 23 90-degree rotation, then decontrols
Unlocking button 221, the effect of the second stage clip 223 makes limited block 2221 enter the horizontal part of stopper slot 2331.
The concrete operations of governor motion 24 are as follows:
Bolt 241 is screwed onto in regulation connecting rod 21, is pulled outwardly shell 242, makes shell 242 depart from conic guide 13, so
Rear regulation connecting rod 21 just can move forward and backward along U-shaped guide groove 11, after correct position, unclamps shell 242, and shell 242 is first
Enter in another conic guide 13 under the effect of stage clip 243, such U-bracket 10 and left earmuff 20 and right earcup 30 relative
Distance has regulated.
If needing each ingredient to dismantle separation one by one；Have only to a bolt 241 Panasonic from regulation connecting rod 21,
Just left earmuff 20 and right earcup 30 can be taken out from U-bracket 10, the most again unlocking button 221 from center limited block
The left end of 222 is backed out, and such earmuff body 23 connects center limited block 222 and takes out from connecting seat 22, then regulation connecting rod 21
Just can extract from the square groove 220 connecting seat 22；Last screw rod connecting portion 232 and warming piece 231 of sponge are from transition part 233
Rotating and go out, the most each ingredient dismantles separation the most one by one.
Above content is only the better embodiment of the present invention, for those of ordinary skill in the art, according to the present invention
Thought, the most all will change, this specification content should not be construed as this
Bright restriction.
