[0026] refer to Figure 5 A friction pad 7 is fixedly connected to one side of the block 68 close to the detection head 611 , and the friction pad 7 is located at the bottom of the processor 2 .

[0027] As a technical optimization solution of the utility model, by setting the friction pad 7, the friction between the contact surface of the block 68 and the detection head 611 can be increased, so as to avoid the small friction between the block 68 and the detection head 611, which may cause the detection head 611 to loosen, thereby improving the use stability of the detection head 611.
