The insertion and locking of the working head 11 is able to be completed simultaneously. Along with the working head 11 is forward plugged to the pants assembly 10, the locking mechanism locks the working head 11 and the connecting frame 3 together. A nursing worker is able to wear the pants assembly 10 on the human body, similar to wearing diapers on the human body, with low difficulty. Whether the pants assembly 10 is worn in place is able to be determined by direct observation through the excretion opening 100. When it is found that the pants assembly 10 is not worn in place (for example, the excretion opening 100 is deflected), the pants assembly 10 is able to be adjusted in time to prevent the pants assembly 10 from being not worn in place, thereby preventing the subsequent working head from being not worn in place, and reducing the probability of the resulting problems such as leakage of excreta. The pants assembly 10 is able to be worn on the human body in advance. When the working head 11 needs to be connected (based on the willingness of the human body for excretion), the working head 11 is able to be directly forward plugged to the pants assembly 10 very quickly and conveniently. The working head 11 and the pants assembly 10 is able to be quickly connected. The working head 11 is able to be directly inserted and fixed to the pants assembly 10. The working head 11 is able to be quickly connected more timely in response to the excretion requirement, thereby improving the use experience of a patient. Based on this design, since the working head 11 is able to be quickly and simply connected, during the routine time when excreta does not need to be received, the pants assembly 10 is able to be worn on the human body, but the working head 11 is not connected so as to enable the human body to be more relaxed and comfortable, and improve the use experience of the patient. When the excreta needs to be received, the working head 11 is quickly connected to the pants assembly 10. After the excrement collector is worn on the human body, the human body is able to excrete feces into the excretion recess 40.
