The working principle and the beneficial effects of the scheme are as follows: when the high-frequency transformer is used, two pins of the high-frequency transformer are placed on two sides of the isolation block, the motor is started, the motor rotates forwards to drive the rotating shaft to rotate clockwise, two thread sections with opposite rotating directions are arranged on the rotating shaft, the two rotating sleeves are respectively in threaded connection with the two thread sections, the rotating sleeves are in threaded connection with limiting sleeves, and the limiting sleeves are fixedly connected to the positioning plate, so that the two rotating sleeves are driven to move towards one side of the isolation plate when the rotating shaft rotates clockwise; the opposite ends of the two rotary sleeves are provided with limit rings; the upper surface sliding connection of locating plate has two push pedal, is equipped with the spacing groove on the push pedal, and the spacing ring is located the spacing inslot, drives the push pedal and removes and then promote high frequency transformer's pin to the draw-in groove in the in-process that the swivel mount removed to spacing block one side. Meanwhile, the rotating shaft rotates clockwise to drive the gear to rotate clockwise, the gear drives the rack to move downwards to further drive the connecting rod to move downwards, and the connecting rod drives the pressing plate to move downwards to achieve correction of the pins of the high-frequency transformer. After the pins of the high-frequency transformer are corrected, the motor rotates reversely to bring the push plate and the pressing plate back to the initial positions. The correcting device in this scheme simple structure only needs two pins with high frequency transformer to separate the both sides of spacer block when the operation, then the starter motor can realize the correction work to high frequency transformer pin to greatly reduced staff's working strength, simultaneously here, because the correction to the pin passes through the motor and drives drive mechanism and extrusion mechanism and realize, thereby improved the correction efficiency of high frequency transformer pin greatly.

Further, the pressure plate is in threaded connection with the connecting rod. Through clamp plate and connecting rod threaded connection, can be more quick and accurate realization to the adjustment of clamp plate height.

Furthermore, two side walls of the isolation block close to the clamping groove are respectively positioned on the same vertical surface with the inner wall of the clamping groove. Through such setting, when the push pedal promoted excessively, the draw-in groove also can not crossed to the pin of high frequency transformer for the location of high frequency transformer pin is more accurate.

Furthermore, two transmission mechanisms are arranged, and the two rotating shafts are connected through a belt; the draw-in groove runs through the upper surface of locating plate, the spacing block is parallel with the draw-in groove from the locating plate and extends to the other end from the one end of locating plate. Through setting up two drive mechanism, can realize the correction to two high frequency transformer pins simultaneously to raise the efficiency reduces the energy consumption.
