Escalator handrail driving force measuring device and clamping part used for escalator handrail driving force measuring device

The invention discloses an escalator handrail driving force measuring device and a clamping part used for the escalator handrail driving force measuring device. The measuring device comprises the clamping part and a measuring device body. The clamping part comprises a first clamping half body and a second clamping half body. The second clamping half body and the first clamping half body have the symmetrical shapes. When the first clamping half body and the second clamping half body are installed on an escalator handrail, clamping force can be adjusted relative to the escalator handrail, so that the clamping part is installed on the escalator handrail in a slideable mode. The measuring device is detachably connected to the clamping part and used for moving in opposite directions along the handrail to pull the clamping part to slide on the handrail when the measuring device is connected to the clamping part and the escalator handrail operates. Meanwhile, the friction force applied to thehandrail by the clamping
