Patent attributes
A string clamping device includes a base with two first sidewalls and a movable unit is located between the two first sidewalls and a guide member is connected to an end of the movable unit. A pair of clamping members are pivotably connected between two second sidewalls of the movable unit so as to clamp a string which is guided by the guide member. Each of the two first sidewalls has a first slot and a second slot defined in an inside thereof. The first slots are close to the guide member and inclined to a horizontal plane. Two bearings are connected to the two second sidewalls and movably received in the first and second slots. The movable unit together with the clamping members is pivoted along the inclined first slots when pulling the string such that the string needs not to be bent.
