The inner side of the lower fixing plate is connected to a lower bearing through a lower shaft pin. The lower side of the lower bearing is connected to the reverse thrust clamping rod. The lower end of the reverse thrust clamping rod is connected to the reverse thrust clamping rod block. The reverse thrust clamping rod block is arranged inside the reverse thrust clamping rod. The fixed square tube has a lower notch. The reverse thrust clamping rod block passes through the lower notch and is stuck inside the height adjustment hole. The outside of the reverse thrust clamping rod is connected to a lower limit nut. The lower limit elastic rope passes through the lower limit nut. The lower limit elastic rope is wound around the fixed square tube.

[0006] The outside of the fixed square tube is connected to the upper fixing plate. The upper fixing plate is arranged on the upper side of the lower fixing plate. The inner side of the upper fixing plate is connected to an upper bearing through an upper shaft pin. The upper side of the upper bearing is connected to the pull rod.

The lower end of the reverse pull clamping rod is connected to the reverse pull clamping rod block. The reverse pull clamping rod block is arranged inside the reverse pull clamping rod. The telescopic rod has an upper notch which is arranged on the lower side of the upper fixing plate. The reverse pull clamping rod block passes through the upper notch and is stuck inside the height adjustment hole.

[0007] The shape of the reverse thrust clamping rod block is a regular trapezoid, and the shape of the reverse pull clamping rod block is an inverted trapezoid.

The anti-rotation fixing strips are stuck at the internal corner of the fixed square pipe. The anti-rotation fixing strips can slide longitudinally inside the fixed square pipe. A locking screw is threadedly connected to the fixed square pipe. The inner end of the locking screw is located below the sliding track of the anti-rotation fixing strip.

[0010] Beneficial effects:

[0011] The present invention is safe to use and easy to operate. The inner ends of the anti-reverse push rod block and the anti-reverse pull rod block are trapezoidal structures. Compared with the triangular structure, the trapezoidal structure is more stable when stuck in the height adjustment hole. The anti-reverse push rod block and the anti-reverse pull rod block are installed in opposite directions and cooperate to work, so that the anti-reverse push rod block can limit the upward sliding of the telescopic rod in the fixed square tube; the anti-reverse pull rod block can limit the downward sliding of the telescopic rod in the fixed square tube. When the total length of the fixed square tube and the telescopic rod does not need to be adjusted, the anti-reverse pull rod block is stuck in the upper slot and the height adjustment hole, and at the same time the anti-reverse push rod block is stuck in the lower slot and the height adjustment hole, so that the upward and downward sliding of the telescopic rod in the fixed square tube is restricted at the same time, making the relative structure of the fixed square tube and the telescopic rod stable and safe to use without affecting the performance effect. The lower limit elastic rope can keep it in a vertically taut state, and the anti-reverse push rod block is closely connected to the height adjustment hole, so that the anti-reverse push rod block can be stuck in the height adjustment hole, so that the telescopic rod will not retract into the fixed square tube, ensuring that the total length of the fixed square tube and the telescopic rod will not shrink during the sliding process and is safe to use. When the anti-reverse pull rod block is separated from the height adjustment hole, when lifting the foot during the sliding process, the telescopic rod slides downward under the action of the gravity of the ice skate blade. Because the trapezoidal inclined surface of the anti-reverse push rod block faces upward, during the falling process of the telescopic rod, the anti-reverse push rod block can be squeezed and rotated outward by the telescopic rod, and then separated from the height adjustment hole, so that the telescopic rod can fall. The distance between adjacent height adjustment holes is one unit length. By controlling the height of lifting the foot, the telescopic rod can fall a distance of one unit length. By alternately lifting the foot multiple times, the telescopic rod can fall to the lowest end, reaching the maximum value of the total length of the fixed square tube and the telescopic rod. Bringing the performance to a climax, before use, the telescopic rod is retracted to the innermost part of the fixed square tube, so that the total length of the fixed square tube and the telescopic rod is at the minimum value. The unlocking pull piece is stuck between the fixed square tube and the upper limit nut to limit the rotation of the anti-reverse pull rod and the pull rod, so that the anti-reverse pull rod block is closely connected to the height adjustment hole, and the anti-reverse pull rod block can be stuck in the upper slot and the height adjustment hole, so that the telescopic rod will not slide downward in the fixed square tube, making the length of the fixed square tube and the telescopic rod determined and safe to use during the sliding process. When it is necessary to adjust the position of the telescopic rod in the fixed square tube, pull up the pull ring. When the power cable slides upward, it is very convenient to pull up the unlocking pull piece to separate it from the pull rod. Using the elasticity of the upper limit elastic rope, the anti-reverse pull rod and the pull rod rotate, so that the anti-reverse pull rod block is separated from the height adjustment hole, and the anti-reverse push rod block and the anti-reverse pull rod block cooperate to work, and the fixed square tube and the telescopic rod can realize the adjustment of the length. The positioning rod can limit the position of the pull rod in the middle of the unlocking pull piece, improving the certainty of the relative position between the unlocking pull piece and the pull rod, so that the unlocking pull piece will not be separated from the pull rod due to inertia. The positioning cable is respectively connected to the upper limit nut and the pulling nut, which can limit the position of the unlocking pull piece and is convenient for operation.The anti-rotation fixing strip is fixed on the telescopic rod by welding. The anti-rotation fixing strip is stuck at the internal corner of the fixed square tube. The two anti-rotation fixing strips cooperate to prevent the telescopic rod from rotating within the fixed square tube, enabling the connection line between the lower slot and the upper slot to correspond to the connection line of multiple height adjustment holes, ensuring that the anti-reverse push latch block and the anti-reverse pull latch block can accurately be inserted into the height adjustment holes with accurate positioning. The support tube restricts the position of the power cable, facilitating the adjustment of the power cable during the sliding process. The present invention can continuously increase the height of the stilt ice skates during the sliding process, and the height can be effectively controlled. Lifting the foot once raises the height by one level, enhancing the excitement of the performance during the show and bringing the show to a climax. BRIEF DESCRIPTION OF THE DRAWINGS

The lower side of the fixed convex rod 6 has an ice skate mounting groove 7 which is adapted to the ice skate 8. The middle part of the ice skate 8 is connected to the ice skate mounting groove 7 and is stuck inside the ice skate mounting groove 7 for fixed connection. The lower side of the telescopic rod 4 is connected to the arc mounting plate 10. The arc mounting plates 10 are symmetrically arranged on both sides of the telescopic rod 4 and are stuck on the telescopic rod 4.

The outer side of the fixed square tube 1 is connected to the lower fixing plate 18. The inner side of the lower fixing plate 18 is connected to a lower bearing 45 through a lower shaft pin 19. The lower side of the lower bearing 45 is connected to the reverse-thrust stopping rod 20. The lower end of the reverse-thrust stopping rod 20 is connected to the reverse-thrust stopping rod block 21. The reverse-thrust stopping rod block 21 is arranged inside the reverse-thrust stopping rod 20. The fixed square tube 1 has a lower notch 24. The reverse-thrust stopping rod block 21 passes through the lower notch 24 and is stuck inside the height adjustment hole 36. The outer side of the reverse-thrust stopping rod 20 is connected to a lower limit nut 22. The lower limit elastic rope 23 passes through the lower limit nut 22 and is wound around the fixed square tube 1.

[0043] The outer side of the fixed square tube 1 is connected to the upper fixing plate 26. The upper fixing plate 26 is arranged above the lower fixing plate 18. The inner side of the upper fixing plate 26 is connected to the upper bearing 46 through the upper pin 27. The upper side of the upper bearing 46 is connected to the pull rod 31. The upper end of the pull rod 31 is connected to the upper limit nut 32. The lower side of the upper bearing 46 is connected to the anti-reverse pull rod 28. The lower end of the anti-reverse pull rod 28 is connected to the anti-reverse pull rod block 29. The anti-reverse pull rod block 29 is arranged inside the anti-reverse pull rod 28. The telescopic rod 4 has an upper notch 30. The upper notch 30 is arranged below the upper fixing plate 26. The anti-reverse pull rod block 29 passes through the upper notch 30 and is stuck in the height adjustment hole 36.

[0044] The lower fixing plate 18 and the upper fixing plate 26 have the same structure. The anti-reverse push rod 20 and the anti-reverse pull rod 28 have the same structure. The lower bearing 45 and the upper bearing 46 have the same structure. Referring to the attached Figure 9 specification, the shape of the anti-reverse push rod block 21 is a regular trapezoid, and the shape of the anti-reverse pull rod block 29 is an inverted trapezoid; the anti-reverse push rod block 21 and the anti-reverse pull rod block 29 can also be triangular. The shape of the anti-reverse push rod block 21 is an equilateral triangle, and the anti-reverse pull rod block 29 is an inverted equilateral triangle.

[0045] The outer side of the fixed square tube 1 is connected to the support tube 41. The support tube 41 is arranged above the fixed square tube 1. The middle of the support tube 41 is connected to the foot pedal 3. The inside of the support tube 41 is connected to the power cable 39. The power cable 39 passes through the support tube 41. The upper end of the power cable 39 is connected to the pull ring 40. The lower part of the unlocking pull tab 33 is connected to the positioning rod 34. The positioning rod 34 is arranged on both sides of the unlocking pull tab 33. The upper side of the unlocking pull tab 33 is connected to the pulling nut 35. The lower end of the power cable 39 is connected to the pulling nut 35. The pulling nut 35 is connected to the upper end of the positioning cable 38. The lower end of the positioning cable 38 is connected to the upper limit nut 32. The upper limit elastic cord 37 passes through the upper limit nut 32. The upper limit elastic cord 37 is wound around the fixed square tube 1. The inner side of the pull rod 31 is close to the unlocking pull tab 33. The unlocking pull tab 33 is arranged between the fixed square tube 1 and the pull rod 31. The unlocking pull tab 33 slides on the fixed square tube 1.

[0046] The upper end of the telescopic rod 4 is connected to the anti-rotation fixing strip 16. The anti-rotation fixing strip 16 is symmetrically arranged on both sides of the telescopic rod 4. The anti-rotation fixing strip 16 is stuck at the internal corner of the fixed square tube 1. The anti-rotation fixing strip 16 can longitudinally slide inside the fixed square tube 1. The locking screw 17 is threadedly connected to the fixed square tube 1. The inner end of the locking screw 17 is located below the sliding track of the anti-rotation fixing strip 16.

[0047] The inner ends of the anti-reverse push lever block 21 and the anti-reverse pull lever block 29 are trapezoidal structures. Compared with the triangular structure, the trapezoidal structure is more stable when stuck in the height adjustment hole 36 and is also more convenient. The shape of the anti-reverse push lever block 21 is a regular trapezoid, and the shape of the anti-reverse pull lever block 29 is an inverted trapezoid; the anti-reverse push lever block 21 can limit the upward sliding of the telescopic rod 4 in the fixed square tube 1; when the telescopic rod 4 does not need to be raised, the anti-reverse pull lever block 29 can limit the downward sliding of the telescopic rod 4 in the fixed square tube 1. When the total length of the fixed square tube 1 and the telescopic rod 4 does not need to be adjusted, the anti-reverse pull lever block 29 is stuck in the upper notch 30 and the height adjustment hole 36, and at the same time the anti-reverse push lever block 21 is stuck in the lower notch 24 and the height adjustment hole 36, so that the upward and downward sliding of the telescopic rod 4 in the fixed square tube 1 is restricted at the same time, making the relative structure of the fixed square tube 1 and the telescopic rod 4 stable, and the telescopic rod 4 will not move downward.

[0048] The lower limit elastic rope 23 can maintain a vertical state, and the anti-reverse push lever block 21 is closely connected to the height adjustment hole 36, so that the anti-reverse push lever block 21 can be stuck in the height adjustment hole 36, preventing the telescopic rod 4 from retracting into the fixed square tube 1 and ensuring that the total length of the fixed square tube 1 and the telescopic rod 4 will not decrease during the sliding process.

[0049] The unlocking pull piece 33 slides upward along the fixed square tube 1 and separates from the pull rod 31. Under the action of the upper limit elastic rope 37, the pull rod 31 approaches the fixed square tube 1, and the anti-reverse pull lever block 29 separates from the height adjustment hole 36. In the state where the anti-reverse pull lever block 29 is separated from the height adjustment hole 36, when lifting the foot during the sliding process, the telescopic rod 4 slides downward under the action of gravity. Since the trapezoidal inclined surface of the anti-reverse push lever block 21 faces upward, during the falling process of the telescopic rod 4, the anti-reverse push lever block 21 can be squeezed and rotated outward by the telescopic rod 4, and then separated from the height adjustment hole 36, enabling the telescopic rod 4 to fall. The distance between adjacent height adjustment holes 36 is one unit length. By controlling the height of lifting the foot, the telescopic rod 4 can fall a distance of one unit length. Under the action of the lower limit elastic rope 23, the anti-reverse push lever block 21 is stuck in the height adjustment hole 36 again. By alternately lifting the foot multiple times, the telescopic rod 4 can fall to the lowest end, reaching the maximum value of the total length of the fixed square tube 1 and the telescopic rod 4.

[0050] Before use, retract the telescopic rod 4 to the innermost part of the fixed square tube 1, so that the total length of the fixed square tube 1 and the telescopic rod 4 is at the minimum value. Clamp the unlocking tab 33 between the fixed square tube 1 and the upper limit nut 32 to restrict the rotation of the anti-reverse pull rod 28 and the pull rod 31, so that the anti-reverse pull rod block 29 is tightly connected to the height adjustment hole 36. The anti-reverse pull rod block 29 can be clamped in the upper slot 30 and the height adjustment hole 36, so that the telescopic rod 4 will not slide down in the fixed square tube 1, and the lengths of the fixed square tube 1 and the telescopic rod 4 are determined during the sliding process. When it is necessary to adjust the position of the telescopic rod 4 in the fixed square tube 1, pull up the pull ring 40. While the power cable 39 slides upward, pull the unlocking tab 33 upward to separate it from the pull rod 31. Utilize the elasticity of the upper limit elastic cord 37 to make the anti-reverse pull rod 28 and the pull rod 31 rotate, so that the anti-reverse pull rod block 29 is separated from the height adjustment hole 36, and the length of the fixed square tube 1 can be adjusted. The positioning rod 34 can limit the position of the pull rod 31 in the middle of the unlocking tab 33, improve the certainty of the relative position between the unlocking tab 33 and the pull rod 31, and prevent the unlocking tab 33 from separating from the pull rod 31 due to inertia. The positioning cable 38 is respectively connected to the upper limit nut 32 and the pulling nut 35, which can limit the position of the unlocking tab 33 and facilitate operation. The anti-rotation fixing strip 16 is fixed on the telescopic rod 4 by welding. The anti-rotation fixing strip 16 is clamped at the internal corner of the fixed square tube 1. The two anti-rotation fixing strips 16 cooperate to prevent the telescopic rod 4 from rotating in the fixed square tube 1, so that the connection line between the lower slot 24 and the upper slot 30 can correspond to the connection lines of multiple height adjustment holes 36, ensuring that the anti-reverse push rod block 21 and the anti-reverse pull rod block 29 can be accurately clamped into the height adjustment hole 36 with accurate positioning. The support tube restricts the position of the power cable 39, which is convenient for adjusting the power cable 39 during the sliding process. The present invention is safe to use and easy to operate. It can continuously increase the height of the stilt ice skates during the sliding process, and the height can be effectively controlled. Each time the foot is lifted, the stilt ice skates rise by one height, which improves the excitement of the performance during the performance and brings the performance to a climax.

[0051] A method for using a controllable elevation stilt ice skate, characterized by comprising the following steps:

[0052] First step, manually separate the anti-reverse push rod block 21 and the anti-reverse pull rod block 29 from the height adjustment hole 36 at the same time, slide the telescopic rod 4 into the fixed square tube 1 until it retracts to the innermost end of the fixed square tube 1, adjust the unlocking tab 33 downward, clamp the unlocking tab 33 in the fixed square tube 1 and the pull rod 31, and put on the stilt ice skates to start sliding;

[0053] Second step, when sliding to the position where it is necessary to adjust the overall sliding height, pull the pull ring 40 to pull the power cable 39 to pull the unlocking tab 33 upward, so that the unlocking tab 33 is separated from the pull rod 31, the unlocking tab 33 is opened, and utilize the elasticity of the upper limit elastic cord 37 to make the anti-reverse pull rod 28 and the pull rod 31 rotate, and the anti-reverse pull rod block 29 is separated from the height adjustment hole 36;

[0054] Step 3: During the sliding process, through the foot-lifting action, the telescopic rod 4 moves downward under the gravity of the ice skate blade and presses the anti-reverse push rod block 21, causing the anti-reverse push rod 20 to rotate outward, separating the anti-reverse push rod block 21 from the height adjustment hole 36, and the telescopic rod 4 slides downward in the fixed square tube 1;

[0055] Step 4: By controlling the foot-lifting amplitude, the telescopic rod 4 slides downward until the anti-reverse push rod block 21 snaps into the adjacent upper height adjustment hole 36 under the elastic action of the lower limit elastic rope 23, completing the adjustment of one unit length;

[0056] Step 5: By alternately lifting the left and right feet multiple times until the lower end of the anti-rotation fixing strip 16 abuts against the locking screw 17, restricting the further downward sliding of the anti-rotation fixing strip 16, enabling the sliding heights of both feet to be adjusted to the maximum value, reaching the highest height, and completing the adjustment of the sliding height during the sliding process.

The reverse-thrust preventing rod block passes through the lower notch and is stuck in the height adjustment hole. The outside of the reverse-thrust preventing rod is connected to a lower limit nut. The lower limit elastic rope passes through the lower limit nut. The lower limit elastic rope is wound around the fixed square tube; The outside of the fixed square tube is connected to the upper fixing plate. The upper fixing plate is arranged on the upper side of the lower fixing plate. The inner side of the upper fixing plate is connected to an upper bearing through an upper shaft pin. The upper side of the upper bearing is connected to the pull rod. The upper end of the pull rod is connected to an upper limit nut. The lower side of the upper bearing is connected to the reverse-pull preventing rod. The lower end of the reverse-pull preventing rod is connected to the reverse-pull preventing rod block. The reverse-pull preventing rod block is arranged inside the reverse-pull preventing rod. The telescopic rod has an upper notch. The upper notch is arranged on the lower side of the upper fixing plate. The reverse-pull preventing rod block passes through the upper notch and is stuck in the height adjustment hole; The shape of the reverse-thrust preventing rod block is an equilateral triangle, and the shape of the reverse-pull preventing rod block is an inverted triangle; A support pipe is connected to the outer side of the fixed square pipe. The support pipe is arranged above the fixed square pipe. A footrest is connected to the middle of the support pipe. A power cable is connected inside the support pipe. The power cable passes through the support pipe. The upper end of the power cable is connected to a pull ring. The lower part of the unlocking pull tab is connected to a positioning rod. The positioning rods are arranged on both sides of the unlocking pull tab. A pulling nut is connected to the upper side of the unlocking pull tab. The lower end of the power cable is connected to the pulling nut. The pulling nut is connected to the upper end of a positioning cable. The lower end of the positioning cable is connected to an upper limit nut. An upper limit elastic cord passes through the upper limit nut. The upper limit elastic cord is wound around the fixed square pipe. The inner side of the pull rod is close to the unlocking pull tab. The unlocking pull tab is arranged between the fixed square pipe and the pull rod. The unlocking pull tab slides on the fixed square pipe; The upper end of the telescopic rod is connected to an anti-rotation fixing strip. The anti-rotation fixing strips are symmetrically arranged on both sides of the telescopic rod. The anti-rotation fixing strips are stuck at the internal corner of the fixed square pipe. The anti-rotation fixing strips can slide longitudinally inside the fixed square pipe. A locking screw is connected to the fixed square pipe by threading. The inner end of the locking screw is located below the sliding track of the anti-rotation fixing strip; The usage method of the controllable-elevation stilt ice skate comprises the following steps: First step, manually separate the anti-reverse push rod block and the anti-reverse pull rod block from the height adjustment holes at the same time. Slide the telescopic rod into the fixed square pipe until it retracts to the innermost end of the fixed square pipe. Adjust the unlocking pull tab downward. Clamp the unlocking pull tab between the fixed square pipe and the pull rod. Put on the stilt ice skate and start skating; Second step, when skating to the position where the overall skating height needs to be adjusted, pull the pull ring to pull the unlocking pull tab upward by the power cable, separate the unlocking pull tab from the pull rod, rotate the anti-reverse pull rod and the pull rod, and separate the anti-reverse pull rod block from the height adjustment hole; Third step, during the skating process, through the action of lifting the foot, the telescopic rod squeezes the anti-reverse push rod block, causing the anti-reverse push rod to rotate outward, separating the anti-reverse push rod block from the height adjustment hole, and the telescopic rod slides downward inside the fixed square pipe; Fourth step, by controlling the amplitude of lifting the foot, make the telescopic rod slide downward until the anti-reverse push rod block is clamped into the adjacent upper height adjustment hole under the elastic action of the lower limit elastic cord, completing the adjustment of one unit length; Fifth step, by alternately lifting the left and right feet multiple times until the lower end of the anti-rotation fixing strip abuts against the locking screw, restricting the anti-rotation fixing strip from sliding downward continuously, so that the skating heights of both feet can be adjusted to the maximum value, completing the adjustment of the skating height during the skating process.
