Further, in the present embodiment, as shown in Fig. 2 circumferentially being opened on the lateral wall of the connection end of stack shell 1
Provided with holding tank 11, so as to form the first defining flange in the side of the holding tank 11 of stack shell 1, this first
Three breach connected with holding tank 11 are offered on defining flange respectively, so that the first defining flange shape
Into three first positive claws 2.Penetrated when the connection end of stack shell 1 in receiving hole 31, make three first
When positive claw 2 is each passed through the gap between three the second positive claws 42, three the second positive claws 42 are just all
Slide into holding tank 11.The groove width of holding tank 11 is slightly larger than the thickness of the second positive claw 42, so that
The side wall relative with the first positive claw 2 of holding tank 11 can give the second positive claw 42 to support, Jin Erfang
Only the second positive claw 42 because camera lens is accidentally hit and by shear action, situation about being broken.
Further, in the present embodiment, as shown in Fig. 2 being also formed with being used on the inwall of connecting seat 3
Ring-type second defining flange 33 spacing to the first positive claw 2, the inner diameter of second defining flange 33
Slightly larger than the diameter of the first positive claw 2.When the second positive claw 42 is slipped into holding tank 11, first is positive
Claw 2 is penetrated in the second defining flange 33.So, the first positive claw 2 is just by the second defining flange 33
Limit.
Second embodiment
The difference of second embodiment and first embodiment is, the shape of the connection end of camera lens stack shell 1.
As shown in Figure 3 and Figure 4, Fig. 3 shows the schematic diagram of the lens adaptor of second embodiment of the invention；
