When the lock core shaft 15 slides downward along the first sliding groove 141 and slides out of the notches 131, the lock core bar 13 can slide horizontally on the lock core seat 14.

[0044] Refer to Figure 8 , a driving device 3 is further provided on the lock core shaft 15, and the driving device 3 is used to drive the lock core shaft 15 to slide in the first sliding groove 141 so that the lock core shaft 15 slides out from the notch 131 to achieve the purpose of releasing the lock core strip 13.

[0045] Refer to Figure 8 and Figure 9 , the driving device 3 includes a sliding cover 31 drivingly connected to the lock core shaft 15. The sliding cover 31 is slidably arranged on the lock core seat 14 in the horizontal direction. A long strip-shaped second sliding groove 311 is provided on the sliding cover 31. As shown in the figure, the second sliding groove 311 intersects with the first sliding groove 141. By sliding the sliding cover 31 on the lock core seat 14 in the horizontal direction, the lock core shaft 15 is driven to move up and down in the first sliding groove 141.

[0046] Refer to Figure 6 and Figure 8 , the driving device 3 further includes a pull rope 32 fixedly connected to the sliding cover 31 and a first return spring 33 installed between the sliding cover 31 and the lock core seat 14. The pull rope 32 and the first return spring 33 enable the sliding cover 31 to slide back and forth on the lock core seat 14. Specifically, the pull rope 32 pulls the sliding cover 31 to slide on the lock core seat 14, so that the sliding cover 31 compresses the first return spring 33. After the pull rope 32 is released, the first return spring 33 resets and then pushes the sliding cover 31 to slide.

[0047] Refer to Figure 11 , one end of the pull rope 32 is fixedly connected to the sliding cover 31, and the other end is connected to a pull rope button 6. A U-shaped tube 21 is provided at the front end of the pedal 2. The two ends of the U-shaped tube 21 are respectively connected to the corresponding inner tubes 12 in a penetrating manner.

By pressing the button body 62 towards the button base 61, the second return spring 64 is compressed. When the button body 62 is released, the second return spring 64 resets and pushes the button body 62 to reset, thereby driving the drive shaft 63 to reset, so that the pulling force on the sliding cover 31 on the pull rope 32 disappears, that is, the pull rope 32 releases the sliding cover 31.

[0050] During use, the user presses the button body 62, and the fourth chute 621 on the button body 62 presses the drive shaft 63 to slide in the third chute 611 of the button base 61, so that the drive shaft 63 tightens the pull rope 130 and compresses the second return spring 64;

[0051] The pull rope 130 pulls the sliding cover 31 to slide on the lock core seat 14. The second chute 311 on the sliding cover 31 forces the lock core shaft 15 to slide downward in the first chute 141 of the lock core seat 14, so that the lock core shaft 15 originally stuck in the notch 131 slides out of the notch 131, and the lock core bar 13 is released from the lock core seat 14. By pulling the inner tube 12 fixedly connected to the lock core seat 14, the lock core bar 13 is driven to slide horizontally in the lock core seat 14. After adjusting the length of the telescopic sleeve 1, the button body 62 is released to achieve the purpose of adjusting the length of the telescopic sleeve 1, and further realize the adjustment of the length of the pedal;

[0052] When the button body 62 is released, the second return spring 64 resets and pushes the button body 62 to reset, thereby driving the drive shaft 63 to reset, so that the pulling force on the sliding cover 31 on the pull rope 32 disappears, that is, the pull rope 32 releases the sliding cover 31. The first return spring 33 resets and pushes the sliding cover 31 to slide on the lock core seat 14, so that the lock core seat 14 drives the lock core shaft 15 to slide upward. At this time, the user gently pushes and pulls the pedal 1 so that the lock core shaft 15 is stuck in the corresponding notch 131, and the lock core bar 13 is locked in the lock core seat 14, that is, the inner tube 11 and the outer tube 12 are locked.
