Description
Technical field
The utility model belongs to threaded fastener dismantling device field, and in particular to a kind of spanner and its clamping and holding assembly.
Background technique
Spanner is widely used in needing to disassemble and install the numerous areas of screw thread class connection, spanner type currently on the market
It is various, but the mobile jib of most of spanners is to be fixedly connected with spanner handle, is occupying larger space ratio in keeping and carrying process
It is cumbersome.Authorization Notice No. is CN103753461A in order to solve this problem, the Granted publication date is in 2014.04.30
State's invention patent discloses a kind of combination wrench, and the combination wrench includes mobile jib and spanner handle, the spanner handle between mobile jib
It is flexibly connected, mobile jib end is equipped with dismountable sleeve, and sleeve and mobile jib are detachably fixed by bolt, the sleeve and mobile jib
Fixing assembling, in dismantlement work, sleeve may not just cooperate with hex bolts, need to rotate spanner into certain angle
Enable sleeve and hex bolts cooperating, but the angle that can be rotated in some particular surroundings spanners and little, at this moment
Cooperate sleeve and hex bolts by rotating spanner, spanner 4 be located at can operating space 6 middle position (as shown in Figure 4),
This in turn reduces a part can operating space 6, make natively limited operating space become smaller, cause it is every rotation once have
The angle of limit just needs to cooperate spanner and hex bolts again, and it is low to will lead to working efficiency in this way.
