Description

TECHNICAL FIELD The disclosure relates to the field of vehicle step supporting technologies, and more particularly to a vehicle step stabilizer. BACKGROUND A Chinese patent with an authorization announcement number of CN118618202 B discloses a hidden folding step of a recreational vehicle (RV). The step is deployed from a vehicle body of the RV for use, which inevitably leads to the lack of support for a last pedal of the step. In a related art, there is a support structure including two hinged supporting rods fixed on the last pedal. The supporting rods are designed as telescopic structures. The two supporting rods are in the splayed shape when the support structure is used, and lengths of the supporting rods are adjusted through extending or retracting the supporting rods to achieve support the last pedal. However, it is relatively inconvenient to adjust an angle between the supporting rods of the related art above manually. If the supporting rods need to be extended after a user steps on the last pedal, the user must get off from the last pedal and readjust the supporting rods, which is inconvenient and does not allow for stepless adjustment. SUMMARY An objective of the disclosure is to provide a vehicle step stabilizer to solve technical problems of inconvenient operation, a large volume after storage, a long and wide size and inability to achieve stepless adjustment. In order to achieve the above objective, the disclosure provides the following technical solutions. A vehicle step stabilizer includes two supporting rods rotatably connected to each other and configured for connecting to a last pedal of a vehicle, a bidirectional screw having two thread directions at two ends of the bidirectional screw, a first sliding block and a second sliding block respectively threadedly connected to the two ends of the bidirectional screw. The two supporting rods are rotatably connected to the first sliding block and the second sliding block, respectively. The first sliding block and the second sliding block are configured to move toward or away from each other on the bidirectional screw, thereby moving tops of the two supporting rods closer together or farther apart accordingly. In an embodiment, the vehicle step stabilizer includes a fixing plate configured for fixing on the last pedal of the vehicle and two connecting plates vertically fixed on two sides of the fixing plate respectively. Each of the first sliding block and the second sliding block is slidably connected to the two connecting plates. In an embodiment, a first sliding shaft extends outward from two opposite sides of the first sliding block, and a second sliding shaft extends outward from two opposite sides of the second sliding block. Each of the two connecting plates is defined with a first sliding groove and a second sliding groove for sliding operations of the first sliding shaft and the second sliding shaft respectively; and the two supporting rods are rotatably connected to the first sliding shaft and the second sliding shaft, respectively. In an embodiment, a first balance rod extends outward from the two opposite sides of the first sliding block, a second balance rod extends outward from the two opposite sides of the second sliding block. The two connecting plates define two balance grooves corresponding to the first balance rod and the second balance rod, the first and second balance rods are slidably respectively engaged within the two balance grooves, and the two balance grooves are disposed parallel to the first sliding groove and the second sliding groove. In an embodiment, a bottom surface of the fixing plate is provided with a limiting member for limiting horizontal displacement of the bidirectional screw. In an embodiment, the limiting member includes a securing plate vertically fixed on the bottom surface of the fixing plate. The securing plate is rotatably connected to a demarcation point of the two ends of the bidirectional screw. The bidirectional screw defines a limiting groove used to limit the horizontal displacement of the bidirectional screw in cooperation with the securing plate. In an embodiment, a drive head is fixed to an end of the bidirectional screw, and is configured for driving the rotation of the bidirectional screw. In an embodiment, the two supporting rods are a first supporting rod and a second supporting rod. A rotating member is disposed at an intersection point of the two supporting rods. A side of the rotating member near the first supporting rod is rotatably connected to an end of a first reinforcing rod. Another end of the first reinforcing rod is rotatably connected to the second sliding block. A side of the second supporting rod is rotatably connected to an end of a second reinforcing rod, and another end of the second reinforcing rod is rotatably connected to the first sliding block. The first and second reinforcing rods provide enhanced support to the two supporting rods, and improving force distribution
