Further, described thumbscrew comprises the butterfly ailhead being convenient to exert a force, the screw rod mated with spline screw, and the connecting rod arranged between butterfly ailhead and screw rod and with screw coaxial, and wherein, the diameter of connecting rod is less than the diameter of screw rod.
Install for the ease of thumbscrew, the size of described installation screw is mated with screw rod size, passes for screw rod.
Further, the quantity of described fastening through-hole is greater than two, and its hole wall around Connection Block is arranged, described retreat stop block, thumbscrew and the quantity of spline screw and the quantity Matching of fastening through-hole.
Further, the hole in the middle part of described Connection Block is through hole or blind hole.
Particularly, described retreat stop block comprises the support portion be connected with Connection Block, and position also outwardly convex corresponding to fastening through-hole keeps a retaining gap with Connection Block and the protuberance be connected with support portion, and wherein installation screw is arranged on this protuberance.
Further, described support portion is connected with Connection Block by screw.
Compared with prior art, the utility model has following beneficial effect:
(1) the utility model adds retreat stop block in the fastening through-hole of existing Connection Block, and be equipped with special thumbscrew, transfer inserted block fastening and dismounting can be realized easily, and the retaining gap between retreat stop block and Connection Block effectively prevent thumbscrew exit after come off, can be limited at outside Connection Block after making it loosen, can not lose, very convenient, and its structure is simple, design ingenious, easy to use, be with a wide range of applications, be applicable to applying.
(2) the utility model is by the improvement to common wing bolt, the part of screw rod and butterfly ailhead junction is become the connecting rod that diameter is less than screw rod, screw rod is utilized to screw in coordinating of installation screw during installation, connecting rod and installation screw is made to be larger matched in clearance, relatively rotate flexibly, resistance between screw thread is reduced when screw rod screws in fastening through-hole, make operation more convenient, and utilize the inaccurate contraposition deviation of screw thread to make screw portion cannot exit installation screw when screw rod exits fastening through-hole, effectively prevent the loss of thumbscrew.
(3) the utility model arranges between protuberance and Connection Block and forms retaining gap on retreat stop block, the loss after preventing thumbscrew to exit better.
