Technical scheme adopted to achieve these goals is: the portable hand steered pull bar of a kind of steel tube tower cross-arm, comprise anterior setting and embrace the bar body that folder rear portion arranges retaining mechanism, described armful of folder rear portion arranges stay cord, described armful of folder rear portion arranges spring, described retaining mechanism comprises support bar and locking module, and described support bar is connected with bar body by wing bolt.
Described locking module comprises deck and ratchet arm, and described ratchet arm one end is flexibly connected with deck, and described ratchet arm other end arranged outside ratchet, described ratchet is connected with deck by the elastic card be arranged on deck.
Described stay cord end arranges draw ring, and described bar body outer wall draw ring place arranges two winding post.
Described spring is Compress Spring.
Described armful presss from both sides as scissor-shaped embraces folder, and described armful of folder is anterior U-shaped.
Described armful of folder is flexibly connected with bar body by central rotating shaft.
Described elastic card top arranges switch column.
The utility model adopts locking module to be locked on steel pipe tower rod by this device, then will embrace on insulator string that mounting board arranges in cross-arm front end, top by bar body, pulling scissor-shaped to embrace folder rear portion by stay cord makes the distance between the two-arm of rear portion reduce, and then realize front clamp insulator string, then by wing bolt, support bar and bar body are locked, and and between the cross-arm of bottom shape form an angle, be kept upright when making attendant movable on cross-arm, off-centring will be caused to cause the phenomenon of crank because of this device; The structural principle design of scissors is adopted to embrace folder, between the jig arm afterbody of two armfuls, rear portion, Compress Spring is set, can make under the action of the spring to embrace folder in maximum angle state, and bracing wire is set by between the jig arm of two armfuls, its rear portion, bracing wire arranging stay cord, making when pulling stay cord, the stressed distance of tightening up between compression two armfuls of jig arm of bracing wire can be made, thus realize embracing anterior the tightening up of folder, ensure the support effect of front end.
In the stay cord exit of bar body, two winding post are set, make stay cord can be wound around locking thereon after tension, not only simplify structure but also locking effect is good, portion is flexibly connected with support bar by wing bolt in its back-end, the function of quick locking can not only be realized, and the function of expansion link can be realized, the locking module adopted, itself and handcuffss principle are similar to, the elastic card that deck is arranged, can be locked rapidly by ratchet and elastic card, and switch column is set at an upper portion thereof, can after finishing using, carry out quick removal, not only achieve locking function but also achieve the function that fast dismantling removes, and this apparatus structure is simple, be easy to operation, its practical value has been played to greatest extent under equal resources supplIes, be worth application and promote.
