The utility model is to solve the problems of the technologies described above adopted technological scheme to be:
The coupling shaft that a kind of pipe-dredging flexible axle is connected with electric drill, comprise axis body, plug, bearing pin and spring, described axis body is hollow, the inner chamber of axis body is provided with step, one end of axis body is provided with the groove coordinating with electric drill chuck, the other end of axis body be provided be connected with pipe-dredging flexible axle coordinate fin and spacing fin, coordinate between fin and spacing fin and be provided with draw-in groove; Inner chamber one end and the plug of described axis body are connected and fixed, and the other end and bearing pin are connected, and the step by axis body inner chamber carries out spacingly, and plug is by spring compression bearing pin.
Described groove is U-shaped.
Described plug is screw.
Described screw be following screw wherein any one: (1) one word screw; (2) plus screw; (3) sunk screw; (4) anury screw; (5) hex screw.
Described plug is connected with the interference fit that is connected to of axis body inner chamber.
Described plug is threaded with being connected to of axis body inner chamber; Be that plug is provided with outside thread, the inner chamber of coupling shaft is provided with the internal thread supporting with the outside thread of plug.
compared with prior art, the utlity model has following beneficial effect:
1, the utility model can be realized being connected of pipe-dredging flexible axle and electric drill well, installs firmly, and manufacturing procedure is few, and technique is simple, and processing cost is low.
2, the utility model assembling is simple, and assembling security effectiveness is high, and assembly cost is low.Only need common laborer with once screw-driver can be assembled, without the needed professional skilled worker's assembling of welding, also can reduce the impact of welding on environment simultaneously
3, the utility model has thoroughly been eliminated the issuable various potential safety hazards of existing electric drill connection clamping bar separation design, avoided connecting between round end and attachment post because welding, the issuable rosin joint of pegging graft and be threaded, distortion, disconnection and electric drill reverse the problem that comes off causing, stability and Security have been improved, for the operator of pipe-dredging has created safer operating environment.
4, coupling shaft of the present utility model adopts global design, and simple in structure, volume is little lightweight, and processing and the simple cost of assembly technology are low, for society has reduced energy consumption and saved resource.
the utility model is connected clamping bar processing and the comparison of assembly technology flow process with existing electric drill
