And simultaneously, the stability of the composite material can be improved. The simple and stable fixing effect is realized.

As another preferred technical scheme, at least two groups of the door opening arms and the refrigerator handle clamps matched and fixed with the door opening arms are arranged.

According to the refrigerator door design of different refrigerators, can set up a plurality of arms of opening a door and rather than supporting fixed refrigerator handle anchor clamps to need not to move the refrigerator in detecting again, realize once putting the back, the detection according to the preface of a plurality of refrigerator doors.

According to a further preferable technical scheme, the plurality of door opening arms are respectively fixed on the longitudinal support rods on different sides, and correspondingly, the motor is arranged on the longitudinal support rods.

Meanwhile, as an optimal technical scheme, a foot pad is arranged at the contact end of the longitudinal support rod and the ground.

Adopt the utility model discloses a technical scheme afterwards, can satisfy different sizes on the market, different grade type for example single door, three doors, to running from opposite directions the detection of refrigerator such as door, cross, the device stable in structure simultaneously can be at the uniform velocity, the accurate action of opening, closing the door of accomplishing under the effect of motor, really realizes the full-automatic test that need not on duty.
