Fig. 2 be in Fig. 1 B to oblique view.
Respectively be designated in accompanying drawing: 1, installing rack, 11, backing plate, 12, screw hole, 2, traction wheel one, 21, ship and resell on another market one, 3, connecting plate, 31, ship and resell on another market two, 32, ship and resell on another market three, 33, clothes-hook one, 4, traction wheel two, 5, extension spring, 6, U-shaped plate, 61, clothes-hook two, 62, hanging groove, 63, positive six side's counterbores, 7, screw rod, 8, nut, 9, fixed head.
Embodiment
Be described further below in conjunction with the adjusting device of accompanying drawing to a kind of traction wheel tensile force of the present invention:
As seen from Figure 1, the present invention it comprise installing rack 1, traction wheel 1, connecting plate 3, traction wheel 24, extension spring 5, U-shaped plate 6, screw rod 7, nut 8 and fixed head 9, described traction wheel 1 is by one 21 upper ends being arranged on installing rack 1 of shipping and reselling on another market, one end of described connecting plate 3 is by 3 32 centres being arranged on installing rack 1 of shipping and reselling on another market, described traction wheel 24 is by 2 31 other ends being arranged on connecting plate 3 of shipping and reselling on another market, and the centre of described connecting plate 3 is provided with clothes-hook 1; One end of described extension spring 5 is arranged on clothes-hook 1, and the other end is arranged on clothes-hook 2 61, and described clothes-hook 2 61 is arranged on one end of U-shaped plate 6, and the other end of U-shaped plate 6 is provided with screw rod 7; The below of described installing rack 1 is provided with fixed head 9, and the other end of described screw rod 7 is connected with nut 8 through after fixed head 9; The lower end of described installing rack 1 is provided with backing plate 11, and described backing plate 11 is provided with four screw holes 12.
Method of operation of the present invention is, first utilizes screw to be fixed on the ground by backing plate 11; The copper cash that will draw again or semi-finished product electric wire from traction wheel 1 around to traction wheel 24 place, according to the copper cash of traction or the tensioning degree of semi-finished product electric wire, adjust its tensile force, method of adjustment is: rotate clockwise nut 8, screw rod 7 will strain extension spring 5, the elastic force of extension spring 5 becomes large, by the copper cash on tension traction wheel 1 and traction wheel 24 or semi-finished product electric wire, thus can increase tensile force; When counter clockwise direction rotating nut 8, extension spring 5 is under the promotion of screw rod 7, and elastic force diminishes, and the copper cash on traction wheel 1 and traction wheel 24 or the tensile force of semi-finished product electric wire also can reduce thereupon.
