The sunken region has a first lateral side, a lower bottom and a second lateral side. The first lateral side and the second lateral side are located on two sides of the sunken region and respectively connected with two sides of the annular region. The annular region covers a back of the user's finger. The lower bottom of the sunken region contacts against a finger pulp of the user's finger. The first lateral side and the second lateral side respectively contact against lateral sides of the finger. The detection assembly is disposed inside the case and includes a first detection module and a second detection module respectively located on the first lateral side and the second lateral side.
