Preferably, the claw 52 is 4-9 millimeters with the section width D 4 that is engaged of liner flange 31.When the section is less than 4 It when millimeter, will cause that keying strength is inadequate, need to increase the thickness of claw 52 or liner flange 31, when the section is greater than 9 millimeters When, the shift motion that will cause clamp 50 is too big, is not easy to control and operate.

Preferably, the clearance D 5 of the joint face 523 and liner flange 31 is 0.8-2.5 millimeters.When the gap is less than 0.8 When millimeter, clamp 50 is easy to directly contact liner flange 31 in moving process, causes the coating on liner flange 31 de- It falls, when the gap is greater than 2.5 millimeters, will cause occlusion interval width and become smaller, influence chucking power.

Preferably, the clearance D 3 of the lower card face 522 and side wall of inner is greater than the joint face 523 and liner flange 31 Clearance D 5.So clamp, when movement is sealed, joint face 523 can first touch liner flange 31, therefore can be to avoid lower card face 522 touch side wall of inner, to avoid the occurrence of that lower card face 522 first touches side wall of inner and liner flange 31 does not support connection Face 523 causes claw 52 to easily deform.

Preferably, the inner cover outer edge is concordant with the liner flange outer edge.To facilitate claw 52 to press from both sides the two It holds.

To sum up, the present embodiment has the advantages that

The height H of claw is greater than the clearance D of liner flange and liner in the present embodiment.So claw will not enter liner In the clearance space that flange is formed with liner, so be not in " false sealed " phenomenon that claw only clamps inner cover, so Can not be costly prevent such security risk.
