Engaging module

An engaging module comprising a male engaging element and a female engaging element, and the male engaging element assembled with the female engaging element along an assembling axis, wherein

• the male engaging element has
• a first casing having
• two ends;
• an assembling end formed on one of the two ends of the first casing;
• and
• an assembling hole formed in the assembling end of the first casing;
• multiple matching structures disposed around an external surface of the first casing, and each one of the multiple matching structures having
• a guiding notch being V-shaped and formed on the external surface of the first casing adjacent to the assembling end of the first casing;
• an extending channel formed on the external surface of the first casing, communicating with the guiding notch, and obliquely extended away from the assembling end of the first casing;
• a positioning channel formed on the external surface of the first casing, connected to and communicating with the extending channel opposite to the guiding notch, and having two ends;
• a positioning area formed on one of the two ends of the positioning channel that obliquely extends away from the assembling end of the first casing;
• and
• a limiting area formed on the other one of the two ends of the positioning channel that obliquely extends toward the assembling end of the first casing, and communicating with the positioning area;
• and
• wherein the guiding notches of the multiple matching structures are connected to and communicate with each other;
• a first magnetic element disposed in the assembling hole of the first casing;
• and
• the female engaging element has
• a second casing having
• two ends;
• a mounting end formed on one of the two ends of the second casing for the assembling end of the first casing to extend into the second casing;
• a mounting hole formed in the mounting end of the second casing;
• and
• multiple positioning protrusions formed on and protruding from an internal surface of the second casing and respectively corresponding to the multiple matching structures of the male engaging element;
• and
• a second magnetic element disposed in the mounting hole of the second casing, and selectively and magnetically attracted to the first magnetic element;
• wherein the multiple positioning protrusions respectively enter or leave the positioning channels via the guiding notches and the extending channels of the corresponding matching structures.
