Second bevel gears 14 are fixedly mounted on the ends of the two drive screws 12 that are close to each other.

In use, the rotation of the crossbar 11 drives the first bevel gears 13 to rotate, the rotation of the first bevel gears 13 drives the second bevel gears 14 to rotate, and the rotation of the second bevel gears 14 drives the drive screws 12 to rotate.
[0022] By adopting the above technical solution, the crossbar 11 can drive the drive screw 12 to rotate.
[0023] A No. 1 motor 15 is fixedly installed on the side of the fixed platform 1, and one end of the output shaft of the No. 1 motor 15 is fixedly connected to the crossbar 11 to drive the crossbar 11 to rotate. When in use, the No. 1 motor 15 is turned on to drive the crossbar 11 to rotate.
[0024] By adopting the above technical solution, the No. 1 motor 15 can drive the crossbar 11 to rotate.
[0025] Two movable plates 3 are rotatably mounted on their adjacent sides, with one end of the two movable plates 33 being movably inserted into the test roller 31. A second motor 32 is fixedly mounted on the side of each of the two movable plates 3 on the left side, and one end of the output shaft of the second motor 32 is fixedly connected to the movable plate 33 for installing the test roller 31. When in use, the installation of the test roller 31 is completed when the two movable plates 33 are inserted into the test roller 31 at the same time.
[0026] By adopting the above technical solution, the insertion rod 33 can be used to install the test roller 31.
[0027] Two toothed plates 34 are fixedly installed on the sides of the two movable plates 3 that are close to each other. Mounting rods 22 are rotatably installed on both sides of the two telescopic platforms 2. Transmission gears 23 are fixedly installed on the outer surface of the mounting rods 22, and the transmission gears 23 mesh with the two toothed plates 34 to drive the insertion rod 33 to move. In use, the rotation of the transmission gears 23 drives the toothed plates 34 to move, the movement of the toothed plates 34 drives the movable plates 3 to move, and the movement of the movable plates 3 drives the insertion rod 33 to move.
[0028] By adopting the above technical solution, the transmission gear 23 can drive the insertion rod 33 to move.
[0029] Electric cylinders 21 are fixedly installed on the sides of the two telescopic platforms 2 away from the second motor 32. The end of the output shaft of the electric cylinder 21 near the second motor 32 is fixedly connected to the moving plate 3 for moving the moving plate 3. When in use, the electric cylinder 21 is turned on to drive the moving plate 3 to move.
[0030] By adopting the above technical solution, the electric cylinder 21 is able to move the moving plate 3.
[0031] Both sides of the two telescopic platforms 2 are equipped with limiting devices 4, and the sides of the two limiting devices 4 that are close to each other are in contact with the wheels of the tricycle to limit the electric tricycle.
[0032] By adopting the above technical solution, the limiting device 4 can limit the electric tricycle.
[0033] Working principle: First, turn on motor 15 to drive the crossbar 11 to rotate. The rotation of the crossbar 11 drives the first bevel gear 13 to rotate. The rotation of the first bevel gear 13 drives the second bevel gear 14 to rotate. The rotation of the second bevel gear 14 drives the drive screw 12 to rotate. The rotation of the drive screw 12 drives the telescopic platform 2 to move. The movement of the telescopic platform 2 drives the test roller 31 to move. Adjust the distance between the two test rollers 31 to facilitate testing of electric tricycles of different sizes.
[0034] Next, the electric tricycle is moved onto the telescopic platform 2 so that the outer surface of the electric tricycle wheel comes into contact with the outer surface of the test roller 31. At this time, the wheel of the electric tricycle is limited by the limiting device 4, and the limiting device 4 can move synchronously with the vibration of the electric tricycle.
[0035] Then, turn on motor 32 to drive the insertion rod 33 to rotate. The rotation of the insertion rod 33 drives the test roller 31 to rotate. The rotation of the test roller 31 causes the electric tricycle to vibrate, thereby conducting a vibration test on the electric tricycle.
[0036] Finally, when it is necessary to replace the test roller 31, the electric cylinder 21 is turned on to move the moving plate 3 on one side. At this time, the movement of the moving plate 3 on one side drives the toothed plate 34 to move, thereby driving the transmission gear 23 to rotate. The rotation of the transmission gear 23 drives the moving plate 3 on the other side to move, so that the insertion rod 33 is disengaged from the inside of the test roller 31, completing the disassembly of the test roller 31 and facilitating the replacement of the test roller 31.
[0037] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
