The protection mechanism 320 further includes the driving spring 328 in compressive state, and driving spring 328 is sheathed on conduction
321 outside of column is simultaneously made of insulating materials, one end of driving spring 328 and the conflict of conducting block 2 322, the other end and lower frame
312 contradict, and the elastic force driving conducting block 2 322 of driving spring 328 is done along 321 extending direction of conductive column far from lower frame 312
Movement.
The several groups protection mechanism 320 is installed on upper frame 311 and undercarriage along the circumferencial direction array of fixed column 110
Between body 312, wherein the guide hump on the conducting block 2 322 of one group of protection mechanism 320 is located at the vertical section two of guiding groove 111
Underface, and the distance between two adjacent groups protection mechanism 320 is equal between the vertical section one and vertical section two of guiding groove 111
Distance.
Fuse 325 is put into the clamp area of one 326/ clamping piece 2 327 of clamping piece by user after unscrewing fastening bolt,
Then tightening fastening bolt can install fuse 325 between conducting block 2 322 and conducting block 3 323, due to fuse
325 is normal, i.e., is not blown, so that the elastic force of driving spring 328 can not drive conducting block 2 322 along 321 side of extension of conductive column
To the movement far from lower frame 312 is done, after fuse 325 is blown, conducting block two is can be driven in the elastic force of driving spring 328
322 do the movement far from lower frame 312 along 321 extending direction of conductive column；
Just after the protection mechanism of working condition 320 causes fuse 325 to be blown because of circuit abnormality, the protection mechanism 320
Driving spring 328 drives conducting block 2 322 to do the movement far from lower frame 312, motion process along 321 extending direction of conductive column
In, guided 111 boot segment of the slot guidance of the guide hump being set on the conducting block 2 322, which is done, is directed toward vertical section by vertical section two
One rotation, to make to be directed toward vertical section one by vertical section two around axial do of fixed column 110 from for formula protective device 300 is whole
Rotation, simultaneously because the distance between two adjacent groups protection mechanism 320 be equal to guiding groove 111 vertical section one and vertical section two it
Between distance so that next group of protection mechanism 320 replaces the protection mechanism 320 that fuse 325 is blown, and so on.
Preferably, 300 unitary rotation of formula protective device is replaced certainly and next group of protection mechanism 320 is made to replace 325 quilt of fuse
During the protection mechanism 320 of fusing, due to a variety of factors such as inertia, the conducting block of next group of protection mechanism 320 can be made
Guide hump on 2 322 fails to be accurately positioned in immediately below the vertical section two of guiding groove 111, then makes subsequent protection mechanism
320 replacements can not be normally carried out, in order to solve this problem, at the connection of 111 vertical section two of guiding groove and bootstrap block
It is provided with and limits it for replacing while the protection mechanism 320 that fuse 325 is blown finishes in next group of protection mechanism 320
The limitation protrusion 112 continued to rotate；Insure from replacing 300 unitary rotation of formula protective device and replacing next group of protection mechanism 320
While the protection mechanism 320 that silk 325 is blown finishes, due to the presence of limitation protrusion 112, so that from formula protective device is replaced
300 fail to continue to rotate, and draw so that the guide hump on the conducting block 2 322 of next group of protection mechanism 320 be made to be accurately positioned in
Immediately below the vertical section two of guide groove 111.
More specifically, since the entire replacement process for replacing formula protective device 300 certainly is automatic touch trigger and replacement process
The spent time is shorter, so that user does not exclude circuit abnormality reason also, fuse is substituted in next group of protection mechanism 320
325 protection mechanisms 320 being blown, so that the fuse 325 of next group of protection mechanism 320 is still blown, it is serious to lead
It causes entirely to be blown from the fuse 325 for all protection mechanisms 320 in formula protective device 300, be asked to solve this
It inscribes, is provided in the install housing 100 and makees the bolt 120 replaced and rotated for limiting from for formula protective device 300 is whole,
And bolt 120 is made of insulating materials.
The side of the upper frame 311 towards 100 closed end of install housing is provided with slot, and slot is along fixed column 110

It is equipped with handle 122, reset spring 123 is sheathed on outside pin rod 121, and one end of reset spring 123 contradicts with external step, is another
End is contradicted with 100 closed end of install housing, and the elastic force of reset spring 123 makes pin rod 121 do the movement close to slot slot bottom.
Just after the protection mechanism of working condition 320 causes fuse 325 to be blown because of circuit abnormality, due to bolt 120
Presence so that can not be rotated from for formula protective device 300 is whole, after circuit abnormality is discharged in user, the manual pull-up pin of user
Bar 121 and after disengaging it from slot, can be rotated from for formula protective device 300 is whole, so that next group of protection mechanism 320 is replaceable
The protection mechanism 320 that fuse 325 is blown, subsequent user, which looses one's grip, can be such that pin rod 121 acts in the elastic force of reset spring 123
Under again be located at next group slot in, and so on.
