It on spring gland, is removably attached on hollow spring gland in rear connecting tube, retaining fixture block is engaged with retaining card slot, makes preceding mirror
Pipe cannot the connecting tube rotation after；Retaining set is pulled to make retaining fixture block and retaining card slot when protruding into finger from hollow spring gland
When separation, preceding mirror tube can the connecting tube rotation after.
The rear portion of the further scheme of the utility model, the rear connecting tube is equipped with card in the annular being connected to guide and limit slot
Slot, hollow spring gland are equipped with when latch cooperate with guide and limit slot is installed hollow spring gland press retaining spring from leading
Hollow spring gland certain angle is rotated after being inserted into annular inner card cage to limiting slot, is located in latch on annular inner card cage.
The further scheme of the utility model, the annular inner card cage on the outside of the hollow spring gland, which is equipped with, prevents middle empty
The circlip of spring gland abjection.
The further scheme of the utility model, the rear connecting tube is interior to be equipped with the retaining ring for preventing retaining set from deviating from from front.
The further scheme of the utility model covers after described and is hinged with rotatable peep-proof lid, and peep-proof, which covers, to be set
There is rotational handle.
After adopting the above structure, have the following advantages compared with prior art and effect: first is that when installing and using, retaining covers
Under the elastic force effect of retaining spring, retaining covers upper retaining fixture block and engages with the retaining card slot in preceding mirror tube, and preceding mirror tube can neither
Precession, which can not revolve, moves back, so criminal can not toll breakdown from preceding mirror tube, it is safe and reliable, to substantially increase
Security anti-theft performance.Second is that when opal needs repairing and exchanges finger only need to be protruded into from hollow spring gland, and pulled with finger
Retaining set makes retaining fixture block and retaining exact separation realizes unlock, and rear connecting tube mirror tube can rotate dismounting before, and dismounting is simple
Single, installation and maintenance are exchanged convenient.Third is that covered due to after equipped with rotatable peep-proof lid, can eliminate from directly peeping outdoors
Depending on indoor security risk.
