Intelligent lead tensile tester

The utility model discloses an intelligent lead tensile tester, comprising a tensile frame; a right crossbeam is connected onto the tensile frame; the right crossbeam is fixedly connected with a right clamping mechanism; a force sensor is arranged between the right clamping mechanism and the right crossbeam; the tensile frame is provided with a motor and a left crossbeam; a left clamping mechanism is fixedly connected onto the left crossbeam; a control device is arranged in the tensile frame; a display device is arranged at one side of the tensile frame and is connected with a computer; a protection shield is arranged at the outside of the tensile frame; a protection cover is hinged onto the protection shield; an infrared sensor is arranged on the tensile frame and is connected with an alarm. During work, if the protection cover does not well cover the protection shield, the alarm sounds to prompt an operator to pay attention, so the safety can be greatly improved by the intelligent lead tensile tester.
