[0029] like Figure 1 As shown in the figure, this application provides a fixed support, which is mainly used in the damper indicator mechanism. The fixed support mainly includes a first support 1, a second support 2, and a locking member 3. The first support 1 has a first through hole; the second support 2 has a second through hole; the first through hole and the second through hole correspond to each other, and at least one of the first through hole and the second through hole is an elongated adjustment hole. At least one of the first support 1 and the second support 2 moves along the length direction of the adjustment hole, so that the first support 1 and the second support 2 move closer or further apart; the locking member 3 passes through the first through hole and the second through hole and is inserted into the first support 1 and the second support 2, so that the first support 1 and the second support 2 are locked or unlocked.
[0030] The fixed support provided in this embodiment is provided with a first support 1 and a second support 2 respectively fixedly connected to the two lateral arms of the double wishbone suspension A. The first support 1 and the second support 2 can move closer or further apart to adjust the distance between the two lateral arms. The relative positions of the first support 1 and the second support 2 are fixed by a locking member 3 to fix the distance between the two lateral arms, so as to adapt to double wishbone suspension A with different spans and effectively solve the problem that the shock absorber power indicator cannot test the double wishbone suspension A.
[0031] As an optional implementation, the first support 1 includes a first sidewall 11 and a first fixed wall 12 connected to the first sidewall 11, a first through hole is formed in the first sidewall 11, and the first fixed wall 12 has a first suspension fixing hole; the second support 2 includes a second sidewall 21 and a second fixed wall 22 connected to the second sidewall 21, a second through hole is formed in the second sidewall 21, and the second fixed wall 22 has a second suspension fixing hole; the first sidewall 11 and the second sidewall 21 are opposite to each other, so that the first through hole corresponds to the second through hole; the first fixed wall 12 and the second fixed wall 22 are spaced apart.
[0032] Based on the aforementioned embodiments, in this embodiment, the first support 1 and the second support 2 are disposed on a horizontal plane.

A first suspension fixing hole is formed along the thickness direction of the first fixed wall 12. A second suspension fixing hole is formed along the thickness direction of the second fixed wall 22. The first sidewall 11 and the second sidewall 21 being opposite each other refers to their wall surfaces being opposite each other. The first fixed wall 12 and the second fixed wall 22 are spaced apart to form an appropriate distance, preparing for subsequent distance adjustment.
[0033] In some embodiments, screw holes are provided at the bottom ends of both arms of the double wishbone suspension A, and screws pass through the suspension fixing holes and screw holes to achieve a fixed connection between the fixing support and the double wishbone suspension A.
[0034] As an optional implementation, the first support 1 includes a pair of first sidewalls 11 disposed relatively far apart; the second support 2 includes a pair of second sidewalls 21 disposed relatively far apart; the first first sidewall 11 and the first second sidewall 21 are disposed on the same side, the second first sidewall 11 and the second second sidewall 21 are disposed on the same side, and one of the first sidewall 11 and the second sidewall 21 disposed on the same side is disposed on the outside of the other.
