Embodiment
In order to be able to preferably understand technical scheme, below by specific embodiment and with reference to accompanying drawing
It is described in detail.
Refer to Fig. 1 to Fig. 4, sealing drum base 1, fusing carrier 2 and fuse member component 3, sealing drum base 1 are in unidirectionally opening
Mouthful it is columnar structured, the opening direction of fusing carrier 2 and the self-sealing cylinder base 1 of fuse member component 3 is successively set on sealing drum bottom
(see Fig. 1) in seat 1.Fusing carrier 2 includes support 22 and handle 23.
Fig. 2 a to Fig. 2 c are referred to, support 22 includes cross plate 221 and two side plates 222, the middle part of cross plate 221
Open up and open up a support fixing hole 224 respectively on a through hole 223, four branch fork of cross plate 221；Two side plates 222 are relative
Set, and two side plates 222 are welded on the end of two branch of cross plate 221 fork correspondingly；On each side plate 222
Open up in single-revolution axle mounting hole 225, the gyroaxis mounting hole 225 of two side plates 222 and single-revolution axle 210 is set respectively；Often
An anti-rotation positive stop lug boss 226 is respectively provided with individual side plate 222；Support 22 uses sheet metal component bending forming.
Fig. 3 a, Fig. 3 b and Fig. 4 are referred to, handle 23 includes plastic handle 231 and two eccentric chute connecting rods 232, each
