The main body portion 37 is enclosed to form a part of the first frame opening 30, and the protruding portion 34, the first U-shaped portion 35 and the third U-shaped portion 36 are enclosed at the upper portion of the first frame opening 30. The connecting bracket 3 further includes a decorative cover 38, the decorative cover 38 covers the protruding portion 34, the first U-shaped portion 35 and the third U-shaped portion 36 are attached to an edge of the decorative cover 38, and the recess 33 is formed by recessing a rear side of the decorative cover 38. The second rear-end pre-positioning structure 47 is located between the mating portion 32 and the first end 500 of the hook portion 50; the protruding portion 34 is located in front of the mating portion 32, and in the state that the locking member 5 is buckled with the mating portion 32, the mating portion 32 is located between the protruding portion 34 and the first end 500 of the hook portion 50; and in the state that the locking member 5 is buckled with the mating portion 32, the connected portions of the elastic arm portion 51 and the hook portion 50 are embedded downwards between the protruding portion 34 and the mating portion 32. At least a part of the hook portion 50 and at least a part of the elastic arm portion 51 are connected together to form a tip, and further, the second end 501 of the hook portion 50 and the third end 512 of the elastic arm portion 51 converge together to form an eagle beak shape tip. In the state that the locking member 5 is buckled with the mating portion 32, at least the eagle beak shape tip is embedded downwards between the protruding portion 34 and the mating portion 32.
In the disclosure, a rotation direction of the locking member 5 from the first angle location to the second angle location to achieve buckling with the mating portion 32 is defined as a buckling rotation direction, and a rotation direction which is opposite to the buckling rotation direction and is configured for unlocking the locking member 5 and the mating portion 32 is defined as an unbuckling rotation direction; and in the state that the locking member 5 is buckled with the mating portion 32, when the working head 11 is pulled backwards relative to the connecting bracket 3, the locking member 5 has a tend to rotate in the buckling rotation direction. Therefore, in the state that the locking member 5 is buckled with the mating portion 32, when the working head 11 is pulled backwards relative to the connecting bracket 3, an effect of inhibiting the locking member 5 from rotating in the unbuckling rotation direction is generated, which means that the locking member 5 is not unbuckled with the mating portion 32 when the working head 11 is pulled backwards by an external force, thereby effectively avoiding accidental unbuckling of the locking member 5 and the mating portion 32. In the state that the locking member 5 is buckled with the mating portion 32, contact portions of the locking member 5 and the mating portion 32 are located above the upper side of the rotation axis of the locking member 5, and the hook portion 50 is able to be buckled downwards on the mating portion 32 along with the rotation of the locking member 5; when the locking member 5 rotates relative to the mating portion 32 and is finally buckled in place with the mating portion 32, the rotation direction of the hook portion 50 faces the front lower side; and in the state that the locking member 5 is buckled with the mating portion 32, when the locking member 5 is rotated for unbuckling, the hook portion 50 rotates backwards relative to the mating portion 32, so as to gradually disengage from the mating portion 32. In the state that the locking member 5 is buckled with the mating portion 32, when the working head 11 is pulled backwards relative to the connecting bracket 3, the hook portion 50 pulls the mating portion 32 backwards, at this time, the locking member 5 deforms under the action of a counterforce of the mating portion 32 on the hook portion 50, so as to cause the elastic arm portion 51 to abut against the rear side of the protruding portion 34, the abutment of the protruding portion 34 on the elastic arm portion 51 limits the deformation of the locking member 5 under the action of the external force, which facilitates the structural stability of the locking member 5, and inhibits the accidental unbuckling of the locking member 5 and the mating portion 32.
In the embodiment, the buckling between the first rear-end pre-positioning structure 41 and the second rear-end pre-positioning structure 47 is for the purpose of pre-positioning, thereby facilitating the subsequent operation of the locking member 5 to cooperate with the mating portion 32 and the frame portion 6; as long as the purpose of pre-positioning is met, so the requirement for the buckling stability between the first rear-end pre-positioning structure 41 and the second rear-end pre-positioning structure 47 is very low, in a state that the locking member 5 is unbuckled with the mating portion 32, when the working head 11 is rotated relatively to the connecting bracket 3, the first rear-end pre-positioning structure 41 is able to be unbuckled with the second rear-end pre-positioning structure 47.
The wrapping pant member 10 usually needs to be worn on the human body for a long time, if the working head 11, serving as a relatively heavy object, is connected to the wrapping pant member 10 for a long time and thus is located between the two thighs of the human body, discomfort of the human body is certainly increased; in the embodiment, only the wrapping pant member 10 is worn on the human body and the working head 11 is not connected to the wrapping pant member 10 at regular times (the human body does not excrete); based on the connecting mechanism between the working head 11 and the connecting bracket 3 in the disclosure, the working head 11 is able to be quickly connected to the wrapping pant member 10. Therefore the working head 11 is able to be quickly connected to the wrapping pant member 10 until it is monitored that the user is about to excrete or when the user asks for excretion, the human excrement is still received in time, therefore the human body is able to get rid of the working head 11 at regular times, and thus feels more comfortably.
During assembly, the second front-end pre-positioning structure 46 is first sleeved on the first front-end pre-positioning structure 40 afterwards, and then the first front-end pre-positioning structure 40 and the second front-end pre-positioning structure 46 are used as pivoting connection portions, the first front-end pre-positioning structure 40 is used as an axis of the working head 11, the working head 11 is rotated relative to the connecting bracket 3, until the second connection side 13 is attached to the connecting bracket 3, along with the attachment of the working head 11 and the connecting bracket 3, the first rear-end pre-positioning structure 41 is buckled with the second rear-end pre-positioning structure 47, and along with the attachment of the working head 11 and the connecting bracket 3, the plurality of first teeth 42 are correspondingly meshed with the plurality of second teeth 48; and after the working head 11 and the connecting bracket 3 are pre-positioned together by means of the pre-positioning structures (the first front-end pre-positioning structure 40, the second front-end pre-positioning structure 46, the first rear-end pre-positioning structure 41, and the second rear-end pre-positioning structure 47) described above, the locking member 5 is rotated, so that the locking member 5 is buckled on the mating portion 32. During unbuckling, the handle 511 is able to be pressed down at first to drive the undercut portion 510 of the elastic arm portion 51 to move downwards, so as to deviate from the cross beam 63, and then the locking member 5 is rotated in the unbuckling rotation direction, so that the buckling between the locking member 5 and the mating portion 32 is able to be achieved.
