[0037] A square plate 23 is fixedly connected to the bottom side of the bottom plate 22 to provide support for the bottom plate 22 to prevent the bottom plate 22 from sliding off. The outsides of the two square plates 23 are slidably connected to the inner walls of the front and rear ends of the top of the locking block 9, and the outsides of the two bottom plates 22 are slidably connected to the inner walls of the front and rear ends of the top of the locking block 9. The restriction of the locking block 9 allows the bottom plate 22 and the square plate 23 to slide horizontally. A sealing block 28 is fixedly connected to the left side of the trapezoidal block 20 for sealing the lubricating oil. An oil storage chamber 25 is provided inside the locking block 9 and the fixed block 8 for storing the lubricating oil. The fixed block 8 and the left end of the locking block 9 are rotatably connected with a ball 26 for transferring the lubricating oil to the remaining components. An oil delivery pipe 27 is fixedly connected to the left end of the front side of the main block 10 so that the lubricating oil can be stored inside the locking block 9 and the fixed block 8.

[0038] Reference Figure 1 and Figure 6 The bottom side of the support frame 2 is fixedly connected with a battery compartment tube bottom cover 29 for sealing.

The inner wall of the support frame 2 is slidably connected with a battery column 31. The middle bottom end of the support frame 2 is threadedly connected with a bolt 32. The bolt 32 is used to fix the battery column 31 to prevent the battery column 31 from slipping.

[0039] Working principle: When we install the five-way column 6, we hold the fixing block 8 to drive the five-way column 6 to slide into the inside of the support frame 2, and then align the side block 7 through the snap block 9 to snap, and then push the snap block 9 to slide and make the notch plate 12 slide into the inside of the snap block 9. During the sliding process of the notch plate 12, it will resist the trapezoidal plate 14. At this time, the trapezoidal plate 14 will be forced to drive the button 13 to slide downward, and then drive the limit plate 15 to slide and squeeze the spring 16, so that the spring 16 can The elastic potential energy can be stored, and then a force in the opposite direction is given to the button 13 to reset. After the trapezoidal plate 14 is completely combined with the button 13, the button 13 will not be pushed. At this time, the button 13 will push the limit plate 15 to slide due to the reset force of the spring 16, thereby driving the button 13 to slide upward to clamp the trapezoidal plate 14. On the contrary, the trapezoidal plate 14 can be separated from the notched plate 12, so that the installation and disassembly of the five-way column 6 can be completed quickly without using special tools, thereby saving maintenance and replacement time.

[0040] The fixing plate 30 is removed by removing the bolts 32, and then the battery column 31 is placed inside the support frame 2. The installation position of the rear pedal can resist the battery column 31 and slide down through the five-way column 6, so that the position of the battery in the battery compartment tube is more in line with dynamics. At the same time, when the button 13 drives the strip plate 17 to slide downward, it can drive the connecting plate 18 to slide, and then drive the sliding column 19 to slide, so that the trapezoidal block 20 can be pushed to slide to the left, and then the ball bearing 26 will be driven to slide, so that the hole inside the ball bearing 26 fits with the hole inside the snap block 9, and lubrication is introduced into the interior of the snap block 9. When the button 13 is pressed again, the locking nut 13 is pressed again. After being in position, a series of structures are used to drive the sealing block 28 to reset, so that the sealing block 28 can seal the oil hole of the locking block 9, and the lubricating oil inside the locking block 9 will flow to the inside of the main block 10 through the oil pipe 27, so that the inside of both the locking block 9 and the main block 10 can store the lubricating oil, and after the lubricating oil contacts the ball 26, the surface of the ball 26 can adhere to the lubricating oil, and then the ball 26 will fit with the shaft of the pedal, and when the shaft of the pedal rotates, it can drive the ball 26 to rotate, so that the lubricating oil is automatically applied to the shaft of the pedal, thereby avoiding jamming or jamming, and extending its service life.
