Preferably, described bearing rope is also provided with end cap, described end cap is positioned at the outside of described temperature booster, described end cap is threaded with described canned paragraph, can prevent temperature booster from deviating from, make releasing mechanism entirety more stable simultaneously, the restriction of bearing rope to canned paragraph more easily realizes.
Preferably, described bearing rope two ends are provided with anti-taking off structure.
Preferably, described anti-taking off structure is the cylinder of the band shaft shoulder.
Preferably, one end away from described canned paragraph of described segregation section is provided with screw thread, for being connected with chorista, adopting and being threaded, can be regulated the coupling mechanism force between chorista and canned paragraph by the degree of depth be threaded between chorista with segregation section.
The present invention also provides a kind of Fuse Type to compress the method for releasing of releasing mechanism, and it comprises the following steps:
S91: agent structure be connected with canned paragraph, is connected chorista with segregation section;
S92: to temperature booster energising, bearing rope is fused;
S93: chorista outwards ejects under release spring effect with segregation section.
Compared to prior art, the present invention has the following advantages:
Fuse Type provided by the invention compresses releasing mechanism and method for releasing thereof, bearing rope is utilized to connect the parts needing separation, make it be in impaction state, when singly needing to be separated, temperature booster is energized, temperature raises fusing bearing rope, chorista realizes and being separated of agent structure under the effect of release spring, simplifies the structure of releasing mechanism, reduces its weight, and thrust is little, release impulsive force is little, cost is low, can the miniaturization of implementation space carrying platform, lightweight.
