The invention discloses a cable head manufacturing device, and the device comprises a pedestal and a telescoping rod vertically disposed on the pedestal. The top of the telescoping rod is provided with a circular pipe, and the head of the circular pipe is provided with a cable clamping apparatus. The cable clamping apparatus comprises an upper clamping head and a lower clamping head, wherein the upper clamping head is hinged to one end of the lower clamping head, and the other end of the lower clamping head clamps the head of a cable. An inhaul cable passes through the central part of the upper clamping head, and the tail end of the inhaul cable is fixed with the lower clamping head. The head of the inhaul cable passes through the upper clamping head to be connected with a cam wrench, and a part, between the upper and lower clamping heads, of the inhaul cable is sleeved with a reset spring. The tail part of the lower clamping head is provided with a pipe month, and the head of the circular pipe is inserted into the pipe month and is fixed. The device facilitates the repair of the cable head, and improves the repairing quality and efficiency of the cable head. In addition, the pedestal employs a foldable structure, and the telescoping rod can stretch out and draw back freely, and can draw back when the telescoping rod is not in use. The pedestal is folded, thereby facilitating the carrying and storage.
