The positioning pin is a cylinder with large diameter and the step axle construction that a small diameter cylinders are constituted.
Positioning pin mounting hole on the L shape locating piece is that the diameter light adaptable with positioning pin larger diameter end diameter is blind
Hole.
External screw thread is provided in the positioning pin larger diameter end, the positioning pin mounting hole on L shape locating piece is diameter and positioning
Sell the adaptable tapped blind hole of larger diameter end diameter.
External screw thread is provided in the positioning pin larger diameter end, the positioning pin mounting hole on L shape locating piece is diameter and positioning
Sell the adaptable tapped through hole of larger diameter end diameter.
Positioning pin mounting hole on the L shape locating piece is up big and down small step unthreaded hole, the step unthreaded hole it is big straight
The larger diameter end of diameter end and positioning pin is adapted, and the smaller diameter end of step unthreaded hole and the smaller diameter end of positioning pin are adapted.
The utility model has the advantages that compared with prior art.
The utility model controls the opening degree of elastic ring with adjusting screw rod, and can clamp hexagonal clamping part by spanner and carry out
Operation, disassembly process simply, conveniently, steadily, laborsaving, safety is good.In addition rigidly good while the utility model is at low cost, by force
Degree is high, is unlikely to deform.
