As shown in FIG. 1 , FIG. 2 , FIG. 3 and FIG. 7 , the user can lock the two screw holes 283 of the clamping region 28 by two bolts 282 passing through the two locking holes 282 of the clamping portion 28 of the fixing base 20 . The fixing seat 20 is clamped and fixed to the front fork upper tube F1 of the front fork F, and a handle H is coupled to the inflatable member receiving portion 52 of the movable seat 50; the user's nozzle from the inflatable member 40 The portion 42 injects gas into the movable sleeve 30 Then, the intake passage C formed between the inner circumferential surface of the movable sleeve hole 35 of the movable sleeve 30 and the air guiding portion 1214 of the sleeve guiding portion 121 enters the fixed seat cover of the movable seat 50. The gas-filled space S1 formed between the segment 51 and the movable seat cover 22 of the fixed seat 20, the gas core 424 of the gas nozzle portion 42 can prevent the gas to be recirculated to the external environment; when the bicycle passes through the unevenness The movable sleeve 30 can move up and down along the sleeve guiding section 121 of the coupling member 12, and the two control abutting portions 411 of the inflatable member 40 can be on the inner circumferential surface of the movable sleeve hole 35. The two movable space activities formed between the two movable recesses 1212 of the sleeve guiding section 121 enable the movable seat 50 coupled to the movable sleeve 30 to reciprocally move up and down relative to the fixed seat 20, and utilize the capacity The gas inside the gas space S1 serves as a buffering medium; the guide rod 62 of the guide rod assembly 60 is inserted through the bushing 61 of the guide rod assembly 60 and the guide rod perforations 26 at the bushing 61 and the fixing seat 20 In addition to the inner movement, the guide rod 62 can prevent the movable seat 50 from rotating relative to the fixed seat 20 in addition to the guiding function. The limiting member 63 of the guiding rod assembly 60 is screwed to the limiting member screw hole 621 of the guiding rod 62. When the movable seat 50 is away from the fixing base 20, the limit of the guiding rod 62 is screwed. The member 63 can abut against the lower end of the upper tube joint section 21 to prevent the movable seat 50 from coming off the fixed seat 20.

As shown in FIG. 5, when the front wheel of the bicycle vibrates to reduce the gas in the air-storing space S1 to a minimum volume, the gas in the air-filling space S1 can be connected through the fixed seat sleeve 51 of the movable seat 50. The hole 514 enters the buffer space S2 through the buffer air hole 513 of the fixing seat sleeve 51, and further pushes against the plug 71 of the buffer assembly 70, so that the compression spring 72 is compressed for further buffering. When the gas compression limit in the gas-filling space S1 is avoided, the rider suffers from vibration and feels uncomfortable due to the disappearance of the cushioning action.

As shown in FIG. 2 and FIG. 6, when the bicycle passes through a smooth road surface, the user can rotate the control member 90 to push the gas by the two clamping blocks 92 of the control member 90 that are engaged with the inflatable member 40. The two clamping planes 423 of the mouth 42 rotate the inflatable member 40. When the two control abutting portions 411 of the control section 41 of the inflatable member 40 respectively align and abut against the two inflatable members of the sleeve guiding section 121 When the 1213 arrived, the The movable seat 50 combined with the movable sleeve 30 and the inflatable member 40 cannot move up and down relative to the fixed seat 20, thereby blocking the shock-absorbing function of the present invention; the bicycle pressure type of the present invention can lock the faucet shock absorber. The rider can freely choose whether the suspension function is activated or not according to the condition of the road surface. In addition to the greater flexibility in use, the rider can prevent the bicycle from continuously buffering when driving on a flat road surface. The effect is that the positive force applied to the ground by the front wheel is degraded, the pedaling efficiency is lowered, and the rider consumes more physical strength.
