Patent attributes
A bowstring drawing device for a crossbow has a mounting base, a reeling device and a hook. The mounting base has a rail. The reeling device has a casing with a bottom face and a rail recess defined in the bottom face of the casing to slidably engage with the rail of the mounting base. A wheel assembly is accommodated inside the casing and a crank arm connected to drive the wheel assembly. A clutch is operationally connected to the wheel assembly. The hook is retractably connected to the reeling device by a string. Because the reeling device and the mounting base are engaged with the rail and rail recess, detachment or engagement of the reeling device is convenient. Moreover, the crank arm and the wheel assembly also make the operation of the bowstring drawing device effort-saving.
