Described bolt head is specifically configured to T-bolt head, and described bolt head top is specifically provided with a word rectangular channel, is specifically configured to fillet so that easy for installation on the downside of described bolt head, and the fillet of setting meets anthroposomatology to be prevented from scratching operator.
Described shank of bolt outer wall is specifically provided with external screw thread, and described shank of bolt upper end is specifically provided with cannelure so that can quickly be connected with bolt head so that easy to operate.
Described fine motion shank of bolt is specifically configured to stepped bar, and described fine motion shank of bolt is provided with groove apart from upper and lower end 4 centimeters the most respectively so that ball can be installed with rapid abutting joint.
The steel ball that described ball specifically uses internal diameter to be 50-55 millimeter, described ball is specifically configured to 4 so that degree of taking up space is little, reduces the weakening intensity to fine motion shank of bolt.
Described interior spring specifically uses annular copper spring, described interior spring to be specifically configured to 4, ball can provide bigger potential energy, quickly regulate the opening amplitude size of shank of bolt.
Compared with prior art, this utility model has the advantages that owing to the T-shaped rapid tooth bolt of a kind of novel improved structure of the present utility model is widely used in a kind of technical field of fastening.Meanwhile, the beneficial effects of the utility model are:
1. the setting of this utility model bolt head, the most easy for installation, and the fillet of setting meets anthroposomatology to be prevented from scratching operator.
2. the setting of this utility model shank of bolt, beneficially ball rapid abutting joint install so that operate simpler fast.
3. the setting of this utility model fine motion shank of bolt, is advantageously implemented the micro-positioning regulators to shank of bolt, reduces maintenance cost.
