What is claimed is: 
     
         1 . A buckle comprising:
 a male buckle portion; and   a female buckle portion comprising a female buckle portion body, a channel configured for the insertion of the male buckle portion, and a limiting skirt that is provided or formed at an opening of the channel, the limiting skirt being configured for guiding the male buckle portion into alignment with the opening of the channel.   
     
     
         2 . The buckle according to  claim 1 , wherein the female buckle portion further comprises a latch provided or formed on an inner wall of the channel, wherein the male buckle portion comprises a male buckle portion body, a stop member provided or formed on the male buckle portion body, the stop member having an engagement groove near the male buckle portion body and which is configured for limiting the latch, and a guiding groove which remote from the male buckle portion body and in communication with the engagement groove and is used for guiding the latch to slide into the engagement groove when the male buckle portion is inserted into the channel. 
     
     
         3 . The buckle according to  claim 2 , wherein a width of at least one section of the guiding groove increases with increasing distance from the engagement groove. 
     
     
         4 . The buckle according to  claim 2 , wherein the latch is provided in a middle of the channel and wherein the engagement groove is correspondingly arranged in a middle of the male buckle portion. 
     
     
         5 . The buckle according to  claim 2 , wherein a first outer end of the guiding groove is arc-shaped and wherein a second outer end of the latch is chamfered, such that the latch is guided into the arc-shaped first outer end. 
     
     
         6 . The buckle according to  claim 5 , wherein the engagement groove and the guiding groove are both H-shaped grooves, wherein the female portion has two latches that are respectively arranged one on an inner wall close to the limiting skirt and one on an inner wall away from the limiting skirt of the channel, and wherein second outer ends of the two latches cooperate to form a notch that is configured for assisting sliding of the guiding groove. 
     
     
         7 . The buckle according to  claim 1 , wherein engagement holes are provided on two sides of the female buckle portion body, and the two engagement holes are respectively in communication with the channel; wherein the male buckle portion further comprises two first engagement members which are provided or formed on the male buckle portion body, the two first engagement members being respectively arranged on two sides of the stop member and corresponding to the two engagement holes one to one; and wherein when the male buckle portion slides into the channel, the first engagement members slide into the corresponding engagement holes.
