[0049] When an electric remote-controlled live working clamping tool of this embodiment is used, a control signal can be emitted through a remote control device, and a signal is received through a controller 22 to control a motor 23 to work. The motor 23 drives a screw rod 31 to rotate, and the screw rod 31 rotates to make a movable sleeve 32 move upward, thereby pushing a movable clamp 34 to move upward, and the cable is clamped by the movable clamp 34 and the fixed clamp 35. When it is necessary to withdraw the clamping tool, a reverse process control is performed. When the motor 23 rotates to a specified position and a stall occurs, overload or mechanical failure causes the required torque to exceed the set torque. When the overload value is reached, the torque limiter 33 limits the torque transmitted by the transmission system in the form of slipping. When the overload condition disappears, the connection is restored to prevent mechanical damage. The device uses wireless remote control technology to achieve remote control to realize various operating functions, effectively reducing the labor intensity of personnel, while reducing the operation time and the swing of the live drainage line during operation. At the same time, the contact area between the wire and the wire is increased to ensure that the wire is reliably clamped, thereby improving the safety and reliability during operation. When the clamping force is sufficient, the motor damage caused by stalling is prevented, thereby improving the safety and practicality of the device.
