On behaveing affectedly, the other end of the spring is fixedly connected with one end of sliding block, is welded on one end side wall of the sliding block solid
Determine block.
This setting by pull fixed block on adjusting rod drive slide block movement, make its under the elastic reaction of spring
Elastic telescopic is carried out in fixed link, is inserted into or skids off slot convenient for sliding block to realize to connection structure between screw head and nut
Fixed and disassembly.
Preferably, the side wall of the screw head is equipped with slot, and the other end of the sliding block is through in card slot and slot phase
Matching connection.
This setting sliding block, which is inserted into slot, improves the stability of screw head and screw cap connecting structure, and sliding block skid off it is slotting
The disassembly of nut can be realized in slot, easy to use.
Preferably, the lower end of the adjusting rod is fixedly connected with locating piece, and the fixed block is equipped with and locating piece phase
Locating slot with connection, the top of the nut are equipped with the through slot being connected with installation cavity, and the through slot matches with adjusting rod
It is slidably connected.
This is arranged when needing to turn bolt body, adjusting rod is inserted on through slot to fixed block, at this time locating piece card
Enter in locating slot, so that the connection structure of adjusting block and fixed block block is fixed, then adjusting rod is pulled to make sliding block to bullet
Spring is squeezed, thus sliding block shrink and be detached from slot, being finally drawn up nut can be disassembled, then using general
Logical tool turns bolt body manually, is convenient for grasping bolt body again while enhancing bolt body anti-theft
Make, it is easy to use.
