Stem buffer suspension assembly structure

An assembling method of a stem buffer suspension assembly structure, comprising:

• assembling a buffer assembly inside a main suspension stem, wherein an end of the buffer assembly is exposed out of a top of the main suspension stem;
• mounting a stem and a headset on the exposed end of the buffer assembly, and sealing and covering a most top end surface of the exposed end of the buffer assembly by an upper end cover, wherein the upper end cover is abutted with an upper surface of the stem;
• mounting a lower pressing assembly on a bottom of the main suspension stem, wherein the lower pressing assembly comprises a lower plug member, a locking pin, a pressing member and a limit block, an end of the lower plug member is assembled on the bottom of the main suspension stem to close the bottom of the main suspension stem, and the lower plug member has a locking part recessed on the other end thereof, an end of the locking pin is locked with the locking part, other end of the locking pin is screwed with the pressing member, the limit block is mounted with the locking pin and located between the lower plug member and the pressing member;
• inserting the end, where the lower pressing assembly is disposed, of the main suspension stem into a stem channel of a front buffer frame assembly of a head stem, wherein after the end of the main suspension stem is inserted into the stem channel, a headset is abutted with an upper surface of the head stem and connected to the front buffer frame assembly;
• and
• inserting a special tool into a lower opening of the stem channel of the front buffer frame assembly to drive a pressing member of the lower pressing assembly to push and deform the limit block, so that the limit block is deformed to engage with the inner wall of the stem channel of the front buffer frame assembly, to quickly perform an assembling and mounting operation.
