Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
A kind of torque spanner, as depicted in figs. 1 and 2, comprises wrench body 1, motion bar 2 and fixed bar 3.
Wrench body 1 comprises the arm of force 11, rotating disk 12, single direction ratchet 13, sleeve 14, internal tooth packing ring 15 and spanner upper arm 16 under spanner.
Under spanner, the arm of force 11 comprises lower cover 111 and fixed arm 112, lower cover 111 is disc, disc centre is provided with for the first circular hole through sleeve 14, one end and lower cover 111 outward flange of fixed arm 112 are connected to one, and the other end of fixed arm 112 is fixedly connected with one end of fixed bar 3.
Rotating disk 12 to be located under spanner between the arm of force 11 and single direction ratchet 13, rotating disk 12 is disc, disc centre is provided with for the 3rd circular hole through sleeve 14, and in order to coordinate closely between each structure of wrench body, the middle part of rotating disk 12 upper surface is provided with the groove for holding bicycle single stage flying wheel lower convex platform.
Single direction ratchet 13 is bicycle single stage flying wheel, utilizes the feature of bicycle freewheel single load bearing at this, completes the fastening work of bolt, and bicycle single stage flying wheel shaft hole sleeve is in the middle part of sleeve 14 and inlay.
Sleeve 14 is Hexagonal jacket in cylindrical shape, is applicable to the fastening of hex bolts, and sleeve 14 lateral surface bottom is provided with the retaining washer 141 for locating lower cover 111, makes a sleeve 14 bottom part stretch out lower cover 111 outside, this torque spanner of convenient double-sided use.
