Abstract: A shooting stand with a balancing weight includes a standing frame, a top base, an installing support, a telescopic member, a guide wheel, a rope and a balancing rod. The balancing rod is hinged with the top base, and the balancing rod is extended along a direction away from the top base, the rope goes around the guide wheel, one end of the rope is connected to the telescopic part or the installing support, and the other end is connected to the balancing rod away from the top base. When the telescopic part is extended, the rope is pulled to cause the balancing rod to pivot to approach the cantilever arm; when the telescopic part is retracted, the rope is loosened to cause the balancing rod to pivot away from the cantilever arm, and the rope is pulled to move again. The stability and reliability are improved.

Abstract: A roller shutter with dual operation modes includes a door frame, a roller shutter body, a driving motor, a connecting device, a rotating shaft and a connecting rod. The roller shutter body is slidably configured on the door frame, the rotating shaft is rotatably configured on the door frame, and the rotating shaft is connected with the driving motor through the connecting device. When the connecting device is in a connected state, the driving motor drives the connecting rod to retract or extend the roller shutter body; when the connecting device is a separated state, the rotating shaft is manually operated to drive the connecting rod to retract or extend the roller shutter body. The roller shutter can be opened or closed by manual operation in the absence of power supply or in case of circuit failure, which greatly improves the reliability and convenience.
