[0024] The lower end wall of the working chamber 111 is fixedly connected to a motor frame 112, and the motor frame 112 is rotatably connected to a threaded shaft 109. The upper end surface of the threaded shaft 109 is fixedly connected to the upper end wall of the working chamber 111, and the threaded shaft 109 is threadedly connected to a threaded plate 110. The upper end wall of the working chamber 111 is fixedly connected to four fixing frames 117 distributed in a circumferential array, and the fixing frames 117 are rotatably connected to a rotating rod 118. A steel rope 108 is fixedly connected between each of the connecting plates 107 and the upper end surface of the threaded plate 110, and the steel ropes 108 all pass through the fixing frames 117, so that by driving the threaded shaft 109 to rotate, the threaded plate 110 can be driven downward to pull the clamping plate 103 to move through the steel ropes 108 to perform clamping work.

[0025] A microwave assembly 102 is disposed on the upper side of the clamping box 100, and the clamping plate 103 can clamp four sides of the microwave assembly 102 by a single power source;

[0026] The threaded shaft 109 is coaxially aligned with the clamping box 100 in the vertical direction, so as to evenly drive the clamping plate 103 to move at the same speed;

[0027] The motor frame 112 is fixedly connected with a motor 115, and the motor 115 is fixedly connected with the threaded shaft 109. The motor 115 can drive the threaded shaft 109 to rotate, thereby driving the clamping plate 103 to clamp the microwave component 102.

[0028] The lower side of the clamping box 100 is provided with a through hole 114, and the through hole 114 can conveniently install the motor 115;

[0029] The front side of the clamping box 100 is fixedly connected with a controller 101 , and the controller 101 controls the motor 115 , thereby controlling the up and down movement of the threaded plate 110 , controlling the moving direction of the clamping plate 103 , and selecting whether to clamp or release the microwave component 102 .

[0030] Working principle:

[0031] First, the microwave assembly 102 is placed on the upper end surface of the clamping box 100, and then the motor 115 is started through the controller 101. The motor 115 drives the threaded shaft 109 to rotate, and the threaded shaft 109 drives the threaded plate 110 to move downward. The threaded plate 110 pulls the connecting plate 107 to move through the steel rope 108. At the same time, the steel rope 108 drives the rotating rod 118 to rotate. The rotating rod 118 prevents the steel rope 108 from being worn, and makes the force direction of the connecting plate 107 horizontal.

[0032] The connecting plate 107 drives the sliding plate 116 to move toward the center, stretching the spring 105. At the same time, the sliding plate 116 drives the clamping plate 103 to move toward the center, clamping the four sides of the microwave component 102. Then, the microwave component 102 is tested, so that the four sides of the microwave component 102 can be clamped by one power source, avoiding clamping errors caused by multiple power sources.

[0033] After the test is finished, the motor 115 drives the threaded shaft 109 to reverse, the threaded shaft 109 drives the threaded plate 110 to move upward, the spring 105 drives the sliding plate 116 to move, the sliding plate 116 drives the clamping plate 103 away from the center, and the microwave assembly 102 is released, thereby completing the clamping work.
