Screw.
The height of the holding section is highly consistent with screw trough.The holding section is designed to semi-circular shape, no
It is only easy to process, production cost is reduced, it is also convenient for fastening the extracting tool with the screw trough of anti-dismantle screw, can be easier to
Engaging protuberances are fastened with groove is engaged, so as to dismantle the anti-dismantle screw.
During use, the engaging protuberances of extracting tool are engaged in the engaging groove of anti-dismantle screw, meanwhile, holding section bottom
Face is in close contact with the branch fastener of anti-dismantle screw, and location division bottom surface is in close contact with screw trough, and branch fastener is total to screw trough
It is same to support extracting tool.The hand-held handle of operator, swing handle reaches dismounting tamper spiral shell so as to drive the rotation of anti-dismantle screw
The purpose of nail.
Preferably, the engaging protuberances are " one " font structure.
Preferably, the engaging protuberances are structure as a whole with holding section, the fastness of the structure can be strengthened.
Compared with prior art, anti-dismantle screw of the present utility model and extracting tool have beneficial effect following prominent：
（One）The screw trough of the anti-dismantle screw is designed using eccentric, and " one " font is offered in the side of screw trough
Engaging groove, can not find impetus, so as to the anti-dismantle screw cannot be dismantled using screw disassembling tool on the market；
（Two）The engaging protuberances consistent with the engaging groove structure of anti-dismantle screw, dismounting are provided with the extracting tool
During screw, engaging protuberances fasten with groove is engaged, and operator's swing handle easily can dismantle anti-dismantle screw
Get off；
（Three）The holding section of the extracting tool is designed to semi-circular shape, is not only easy to processing, reduces production cost, also just
Fastened with the screw trough of anti-dismantle screw in by the extracting tool, easier can mutually blocked engaging protuberances with groove is engaged
Close, so as to dismantle the anti-dismantle screw, with good practicality.
