The guide rods 15077 at both ends of the strip 15074 are fixedly connected to the upper and lower mounting cylinders 15072, respectively. When the rotating arm 1506 is adjusted in angle, the mounting cylinder 15072 and the mounting groove 15071 on the rotating arm 1506 rotate relative to each other, ensuring that the clamping blocks 150920 on the upper and lower clamping rods 15084 make perpendicular contact with the pedal surface. This allows the clamping blocks 150920 on both the upper and lower clamping rods 15084 to exert a vertical square force on the pedal surface, improving the clamping effect.

Two plate grooves 15104 are opened inside the fixed base 1502. Two toothed plates 15105 are symmetrically slidably installed inside the two plate grooves 15104. The two toothed plates 15105 are respectively fixedly connected to the two longitudinal connecting plates 15102. A gear mounting groove 15106 is opened inside the fixed base 1502. The upper and lower sides of the gear mounting groove 15106 are respectively connected to the two plate grooves 15104. A drive gear 15107 is rotatably mounted on the pedal. The upper and lower sides of the drive gear 15107 mesh with two toothed plates 15105 respectively. The drive gear 15107 is fixedly connected to the output shaft of the fourth motor 15108. The fourth motor 15108 is fixedly mounted on the fixed base 1502. When the first electromagnet 150812 on the corresponding mounting cylinder 15072 is energized, it generates a repulsive force on the first magnetic block 150811, pushing the four clamping rods 15084 to move to the upper and lower sides of the pedal respectively. The fourth motor 15108 is turned on, causing the drive gear 15107 to rotate, which drives the two longitudinal connecting plates 15102 to move closer to each other. This causes the two rotating arms 1506 on the same side to move closer to each other and rotate, so that the two clamping rods 15084 on the same side clamp the upper and lower surfaces of the pedal, improving the clamping stability of the pedal and facilitating processing. At the same time, mounting cylinders 15072 are equidistantly mounted on the rotating arms 1506, which facilitates clamping pedals of different widths.

[0043] Working principle: In use, the brake pedal of the electric tricycle is placed between two clamping plates 1501. Then, the two cylinders 13 are activated to push the two support plates 12 closer together, so that the two clamping plates 1501 are close together to clamp the pedal. Then, the first motor 6 is activated, so that the first screw 5, which is threadedly connected to the first moving platform 3, moves laterally along the first slide groove 4. At the same time, the second motor 10 is activated, so that the second screw 9 rotates. Since the second screw 9 is threadedly connected to the second moving platform 7, it moves the second moving platform 7 along the second slide groove 8, thus facilitating the movement of the brake pedal to the processing position. When the third motor 14 is activated, the two clamping plates 1501 can rotate, which in turn drives the pedal to rotate for angle adjustment.

[0044] During clamping, since mounting cylinders 15072 are equidistantly arranged on the rotating arm 1506, the first electromagnet 150812 on the mounting cylinder 15072 at the corresponding position is selected, and a repulsive force is generated on the first magnetic block 150811, pushing the clamping rod 15084 to move outward, so that the clamping rods 15084 on the upper and lower mounting cylinders 15072 move to the upper and lower sides of the pedal respectively. The fourth motor 15108 is turned on, so that the drive gear 15107 rotates. Since the drive gear 15107 meshes with the upper and lower tooth plates 15105, it drives the two longitudinal connecting plates 15102 to move closer to each other. This causes the two transverse rods 15103 on the longitudinal connecting plates 15102 to generate a pushing force on the extension rods 15101 at one end of the two rotating arms 1506 on the same side, so that the two rotating arms 1506 move closer to each other and rotate, so that the upper and lower clamping rods 15084 move closer to each other to clamp the pedal, thereby improving the fixing stability of the pedal and improving the processing stability of the pedal.

[0045] When increased clamping force is required, the sliding blocks 15087 on both sides of the moving block 15083 move to the end of the sliding groove 15086 away from the end cylinder 15088. The second electromagnet 150913 is energized, generating a repulsive force on the second magnetic block 150914, pushing the retaining sleeve 150910 towards the sliding block 15087, so that the retaining sleeve 150910 presses and connects the end of the connecting groove 150916. When the first electromagnet 150812 is energized, the side plate 15098 moves with the push block 15089, causing the spring of the third spring 15096 to compress. After the retaining sleeve 150910 moves, it connects the connecting box 15091 and the connecting cylinder 15092. At this time, the first Piston 15093 moves toward connecting box 15091 under the elastic force of third spring 15096, thereby pushing air into inner cavity 150915, thus generating pressure on second piston 150923. After pushing extrusion block 150924 to move, it generates pressure on pressure block 150922, pushing pressure block 150918 toward clamping block 150920. As clamping block 150920 moves with pedal surface, the compression force of sixth spring 150921 increases, which increases the pressure of clamping block 150920 on pedal. Subsequently, under the action of upper and lower clamping blocks 150920, the clamping effect on pedal is improved, further improving pedal processing stability.

[0046] Because a longitudinal strip 15074 is provided between the upper and lower mounting cylinders 15072, and the guide rods 15077 at both ends of the longitudinal strip 15074 are fixedly connected to the upper and lower mounting cylinders 15072 respectively, when the rotating arm 1506 is adjusted in angle, the clamping blocks 150920 on the upper and lower clamping rods 15084 are perpendicular to the pedal surface, so that when clamping, the clamping blocks 150920 on the upper and lower clamping rods 15084 can generate a vertical square force on the pedal surface, thereby improving the clamping effect.
