Since the ball screw 7 is connected to the mounting seat 5 through a thread, the ball screw 7 can be rotated through the groove at the tail of the ball screw 7 to adjust the tightness of the fit between the ball screw 7 and the locking hole 10; a locking ring 8 is fixedly installed on the linkage shaft 3, a protrusion 9 matching the locking groove 6 is arranged on one side of the locking ring 8, and locking holes 10 matching the ball screw 7 are arranged on both sides of the protrusion 9. When the linkage shaft 3 is rotated until the protrusion 9 falls into the locking groove 6, the ball of the ball screw 7 will sink into the locking hole 10.

[0025] Both ends of the linkage shaft 3 are provided with threaded truncated cone rings 11, the outer side of the threaded truncated cone ring 11 is provided with threads and is evenly divided into four petals along the radial direction, a hexagonal prism 13 is fixedly installed in the threaded truncated cone ring 11 by means of a fastening bolt 12, and an axial connecting rod 14 is fixedly installed at one end of the hexagonal prism 13 away from the linkage shaft 3.

[0026] The shaft connecting rod 14 is provided with a first mounting groove 15 extending in the length direction, and an auxiliary connecting rod 16 is slidably installed in the first mounting groove 15 by the cooperation of a bolt and a nut. The relative positions of the shaft connecting rod 14 and the auxiliary connecting rod 16 can be slidably adjusted by loosening the bolt and the nut. The auxiliary connecting rod 16 is provided with a second mounting groove 17 extending in the length direction, and an arc-shaped mounting groove 18 is provided at one end of the auxiliary connecting rod 16 close to the linkage shaft 3; the auxiliary connecting rod 16 passes through the second mounting groove 17 and the arc-shaped mounting groove 18 respectively by two bolts, and then passes through the first mounting groove 15 and is fixedly installed on the shaft connecting rod 14 with a nut. The bolts and nuts in the arc-shaped mounting groove 18 can be loosened to adjust the shaft connecting rod 14 and the auxiliary connecting rod. The relative angle of the connecting rod 16; a pressure rod 19 is fixedly installed on the auxiliary connecting rod 16 located on the right side of the linkage shaft 3, and the pressure rod 19 is a rotating bearing; an auxiliary pedal 20 is installed on the auxiliary connecting rod 16 located on the left side of the linkage shaft 3, and an adjustment seat 21 is provided on the lower side of the auxiliary pedal 20. The auxiliary pedal 20 is fixedly installed on the auxiliary connecting rod 16 by the cooperation of the adjustment seat 21 and the bolt. The adjustment seat 21 is also provided with an arc-shaped adjustment groove 22, and an adjustment bolt 23 is provided in the arc-shaped adjustment groove 22. The adjustment bolt 23 passes through the arc-shaped adjustment groove 22 and the corresponding auxiliary connecting rod 16. The relative angle of the auxiliary pedal 20 and the auxiliary connecting rod 16 can be adjusted by loosening the nut corresponding to the adjustment bolt 23 and another nut on the adjustment seat 21.

[0027] like Fig.10 As shown, the left-foot delayed auxiliary acceleration pedal provided in this embodiment is installed below the driver's seat of the car and is used in conjunction with the accelerator pedal 24.

[0028] When a disabled person is driving, he pulls down the auxiliary pedal 20 or the pressure rod 19 to rotate the linkage shaft 3 and drive the lock ring 8 to disengage from the lock seat 4 and unlock it. At this time, the auxiliary pedal 20 is in use, the pressure rod 19 is in contact with the upper surface of the accelerator pedal 24, and the auxiliary pedal 20 extends to the left side of the brake pedal 25. When the auxiliary pedal 20 is pressed with the left foot, the pressure rod 19 simultaneously presses down the accelerator pedal 24, thereby achieving the purpose of controlling the accelerator with the left foot.

[0029] When a normal person drives, he pushes the auxiliary pedal 20 or the pressure rod 19 upwards, the linkage shaft 3 rotates upwards and the protrusion 9 of the locking ring 8 falls into the locking groove 6, and the marble of the ball screw 7 sinks into the locking hole 10 under the action of the spring, locking the linkage shaft 3. At this time, it is in the storage state and does not affect normal driving.

[0030] The above-mentioned embodiment only expresses one implementation method of the utility model, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
