[0023] Example

[0024] like Figure 1As shown, a manual car transmission shifting test auxiliary device includes a base 11, the cross-section of which is an inverted T-shape, the bottom of which is a horizontal bearing surface 12, a connecting plate 13 is vertically provided above the bearing surface 12, and a support frame 14 is connected above the connecting plate 13. The support frame 14 is used to install the shifting control.

[0025] The support frame 14 has a mounting platform 15 fixedly installed on its upper end surface. A rotating block 16 is connected to one side of the support frame 14. The rotating block 16 is located below the mounting platform 15. The gear shifting control is connected to both the rotating block 16 and the mounting platform 15.

[0026] To facilitate the installation of the gear shifter, both the rotating block 16 and the mounting platform 15 are provided with connecting grooves 17. The connecting grooves 17 are through grooves, which facilitate the gear shifter to be fixedly installed by bolts 18.

[0027] To ensure a stable connection to the shift lever, the rotary block 16 and the support frame 14 are movably connected.

[0028] An extension frame 19 is installed on the side wall of the support frame 14. The extension frame 19 and the support frame 14 are movably connected and can slide up and down relative to each other. One end of the extension frame 19 is connected to a pad 24, which is connected to the support frame 14. The other end of the extension frame 19 is connected to the rotating block 16.

[0029] To facilitate movement between the extension frame 19 and the support frame 14, one of the gaskets 24 or the support frame 14 is provided with a connecting groove 17, which is a slotted groove. The other is rotatably mounted with a bolt 18, which fixes the extension frame 19 and the support frame 14 together. At the same time, the bolt 18 can slide in the connecting groove 17, with the slotted groove in the sliding direction, which facilitates relative movement of the bolt 18 in the connecting groove 17.

[0030] like Figure 3 As shown, to further ensure the stability of the relative sliding direction, at least one of the connecting grooves 17 or bolts 18 is provided in pairs to prevent relative rotation between the extension frame 19 and the support frame 14, which would affect normal sliding operation.

[0031] To facilitate the movement of the rotating block 16 in the horizontal direction, a connecting frame 26 is horizontally connected to the extension frame 19. The connecting frame 26 and the extension frame 19 are connected by a connecting groove 17 and a bolt 18. The connecting frame 26 is connected to the rotating block 16.

[0032] The gear shifter not only has length changes but also angle changes. For easy installation, the rotating block 16 and the connecting frame 26 are rotatably connected. A fixing block 20 is provided on the back side of the rotating block 16. The ends of the fixing block 20 and the connecting frame 26 are rotatably connected by bolts 18. Bolts 18 are both a rotating shaft and a locking structure. When bolts 18 are loosened, the rotating block 16 can rotate around the end of the connecting frame 26. When bolts 18 are tightened, the angle of the rotating block 16 is fixed.

[0033] like Figure 2 As shown, to accommodate test operations, the support frame 14 and the base 11 are connected by a sliding connection, which facilitates control of the height of the shift lever. Either the support frame 14 or the base 11 is provided with a connecting groove 17, and the other is rotatably mounted with a bolt 18. The connecting grooves 17 are all slotted grooves, and the bolt 18 extends into the connecting groove 17. There are at least two connecting grooves 17, and the two connecting grooves 17 are located on the same straight line or parallel to each other to prevent rotation between the support frame 14 and the base 11.

[0034] Furthermore, the base 11 is provided with corner plates 21 on both sides of the connecting plate 13, the support frame 14 is located between the two corner plates 21, and the support frame 14 is provided with side plates 25 on both sides. The side plates 25 and the corner plates 21 abut against each other and slide up and down. The corner plates 21 restrict the support frame 14 to prevent the support frame from moving.

[0035] The bearing surface 12 of the base 11 is provided with several through holes 22. The bearing surface 12 is connected to the fixing bolts 18 through the through holes 22, thereby fixing the base 11 and facilitating the test.
