When the motor 31 drives the limit arm 1 to rotate and be blocked (the load is too large), the motor 31 is forced to increase the power to increase the driving force for driving the limit arm 1 to rotate, because the main shaft 311 is fixedly connected with the load limiting roller 321, the motor 31 rotates to generate the driving force, the driving force is reacted on the load limiter 32, when the driving force exceeds the limiting force for limiting the rotation of the main shaft 311 provided by the load limiter 32, the main shaft 311 rotates, and then the motor 31 is prevented from continuously increasing the power to provide the driving force, so that the motor 31 is prevented from being damaged due to the too large power.
In the present embodiment, the position limiting arm is disposed at the middle of the base, and in other embodiments, when the position limiting arm is disposed at the side of the base, the motor may be directly or indirectly fixedly mounted on the position limiting arm, and at this time, the side of the motor where the spindle is not disposed does not need to be provided with a rotating shaft.
In other embodiments, the motor is directly or indirectly fixedly mounted on the base, the limiting arm is driven to rotate through the rotation of the spindle, the load limiter is fixedly connected with the spindle, and the load limiter is directly or indirectly fixedly mounted on the limiting arm.
