A fitting sleeve includes multiple second slots defined around an outer wall thereof, and the fitting sleeve is fitted into the receiving tube to be limited by a first locking ring. After a respective one of the multiple first multiple slots corresponds to a respective one of the multiple second slots, the fitting sleeve and the receiving tube are fixed by multiple retainers, and a bottom of the receiving tube is connected with a fixing sleeve. The fixing sleeve has a slidable 2 sleeve spaced therein and is fitted onto the square column, a support seat is locked on a top of the square column and has a first aperture configured to accommodate a screw rod on which a limiting loop and a spring are fitted, and the limiting loop is fitted with an adjustable nut and abuts against the spring. The adjustable nut is fitted to a locating holder, and the screw rod is inserted through the locating holder and has an anti-loose nut locked on a distal end thereof. Two ends of the locating holder are fixed in the receiving tube by two second locking rings respectively, and the square column has four recesses defined on four inner surfaces thereof and configured to receive four wear-resistant sheets respectively. The fitting sleeve is made of wear-resistant material so as to obtain connecting accuracy, wear resistance, and long service life. The screw rod is configured to adjust shock absorption, and the limiting loop is configured to limit a movable travel. The receiving tube includes a first air chamber formed therein, and the support seat includes multiple air holes so as to obtain air-tight shock absorbing effect.

    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, a preferred embodiment in accordance with the present invention.
    With reference to FIGS. 1-8, a single front fork shock absorber of a bicycle according to a preferred embodiment of the present invention comprises: a fork assembly 10 including an orifice 11 defined on a top of the fork assembly 10 and matingly connected with a connection column 21 on a bottom of a shock absorber structure 20, thus connecting a front fork 1 of the bicycle; wherein the shock absorber structure 20 includes an affix segment (A) and a movable segment (B), the affix segment (A) has a connecting sleeve 31 and a square column 32 connected on the connecting sleeve 31, and the movable segment (B) has a receiving tube 40 in which multiple first slots 41 are defined, wherein a fitting sleeve 50 includes multiple second slots 51 defined around an outer wall thereof, and the fitting sleeve 50 is fitted into the receiving tube 40 to be limited by a first locking ring 43, wherein after a respective one of the multiple first multiple slots 41 corresponds to a respective one of the multiple second slots 51, the fitting sleeve 50 and the receiving tube 40 are fixed by multiple retainers 52, and a bottom of the receiving tube 40 is connected with a fixing sleeve 42, wherein the fixing sleeve 42 has a slidable sleeve 60 spaced therein and is fitted onto the square column 32, a support seat 70 is locked on a top of the square column 32 and has a first aperture 71 configured to accommodate a screw rod 72 on which a limiting loop 73 and a spring 74 are fitted, and the limiting loop 73 is fitted with an adjustable nut 75 and abuts against the spring 74. The adjustable nut 75 is fitted to a locating holder 76, and the screw rod 72 is inserted through the locating holder 76 and has an anti-loose nut 66 locked on a distal end thereof, wherein two ends of the locating holder 76 are fixed in the receiving tube 40 by two second locking rings 761 respectively, the square column 32 has four recesses 321 defined on four inner surfaces thereof and configured to receive four wear-resistant sheets 33 respectively, wherein the fitting sleeve 50 is made of wear-resistant material so as to obtain connecting accuracy, wear resistance, and long service life. The screw rod 72 is configured to adjust shock absorption, and the limiting loop 73 is configured to limit a movable travel. The receiving tube 40 includes a first air chamber 44 formed therein, and the support seat 70 includes multiple air holes 701 so as to obtain air-tight shock absorbing effect.
    6
    After the square column 32 is connected on and is inserted through the connecting sleeve 31, it is fixed by a third locking ring
    34.
    The square column 32 has a second air chamber 322 defined therein and has a tail nut 323 locked on a distal end of the square column 32 and configured to close the second air chamber 322, then the screw rod 72 is moveable like a piston.
    An anti-dust cover 80 is defined between the connecting sleeve 31 and the fixing sleeve 42.
    The slidable sleeve 60 is comprised of a fixer 61 and multiple needle rollers 62.
    Referring to FIG. 2, the screw rod 72 has an opening 721 configured to connect a hand tool, such that the hand tool is rotated to drive the adjustable nut 75 to move upward and downward so as to change a press force to the spring 74, thus changing the shock absorption.
    As shown in FIG. 3, when absorbing shock by using the shock absorber structure 20, the movable segment (B) slides downward and upward, and the multiple needle rollers 62 rotates in a clockwise direction.
    As illustrated in FIG. 5, the slidable sleeve 60 is formed on a square shape so as to correspond to the square column 32 of the affix segment (A), and a second aperture 53 of the fitting sleeve 50 is 7 square so as to fit on an outer wall of the fitting sleeve 60, hence the fitting sleeve 50 slides on the square column 32, and when the fitting sleeve 50 rotates with the receiving tube 40, it actuates the square column 32 to rotate.
    With reference to FIG. 8, a bicycle 90 includes a handle assembly 91, a front wheel 92, and a frame 93, wherein the front fork 1 is configured to connect the handle assembly 91, the front wheel 92, and the frame 93, and when the handle assembly 91 is rotated, the front wheel 92 is driven to rotate as well.
    While various embodiments in accordance with the present invention have been shown and described, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
