The utility model is set to further: be provided with ratchet device between described clutch gear and screw rod, described ratchet device comprises the internal tooth being coaxially arranged at clutch gear, described bolt rotary is connected with ratchet, described ratchet is connected to internal tooth, described screw rod is provided with the slot to make way for described ratchet activity, be provided with elastic supporting member for supporting optical member between described slot to make way and ratchet, described cavity overcoat is connected with the register pin for reverse rotation.
By adopting technique scheme, when not needing movable clamp to close up, operating personnel by taking out positioning pin, thus are merely able to single-direction transmission in fabric tension process, prevent and make because of maloperation handle turn round the precision reducing and measure after having stretched.
The utility model is set to further: described governor motion is included in the adjuster bar be slidably connected in cavity, and described adjuster bar one end abuts described elastic component, and the other end is connected with described handle threads and stretches out handle.
By adopting technique scheme, by rotary regulating lever, adjuster bar is moved in handle, thus the elastic force that compression elastic piece and then lifting clutch pawl are subject to, change the nominal load of overrunning clutch mechanism.
The utility model is set to further: the side of described adjuster bar relative resilient part one end is provided with scale, and described handle is provided with the form for scale display in correspondence position.
By adopting technique scheme, can scale be seen by window-operating personnel, and nominal load size can be calculated.
