[0020] (1) This invention uses a conveying device to drive the electric oven to a designated position for energy efficiency testing. During the testing, the electric push rod drives the push plate to clamp the electric oven, so that the electric oven body is always kept in the middle position, preventing the testing device from being too close or too far away from the electric oven body, causing the electric oven to be unable to be accurately inserted into the access port, affecting the testing of the electric oven's energy efficiency. At the same time, the elastic telescopic rod can play a buffering role during the clamping process to prevent the electric oven from being damaged by the clamping and causing economic losses.

[0022] (3) This invention drives the slide rod to slide by rotating the turn plate, and uses the slide rod to drive the connecting block to limit the other electric ovens on the conveying device, so as to prevent the two devices from colliding and causing damage to the equipment. At the same time, when the equipment is between the connecting blocks, the limit will cause the slide rod to shrink, and the slide rod will contact the controller to close the electric push rod, so as to prevent the electric oven from being damaged by the connecting block when it is limited when it fails to fully enter the designated area, thereby affecting its use.

[0023] (4) This invention uses a pulley to contact the conveying device and a guide rod to eliminate static electricity on the conveying device, thereby preventing static electricity from being generated by long-term friction of the conveying device, which may affect the accuracy of the detection energy efficiency during detection. At the same time, a concave plate is used to contact the conveying device to prevent the edge of the conveying device from warping up and affecting the stability of the equipment.
