A quick-release tool holder

Abstract

The present invention discloses a quick-release blade holder, comprising a blade body, hook portions spaced apart at the front and rear ends on the top of the blade body, and connecting ribs connecting the two hook portions. A blade portion with a trapezoidal cross-section is provided at the bottom of the blade body, and the bottom edge of the blade portion is in an inverted bow shape with the front and rear ends being wider than the center. This design increases the bottom width of the blade in contact with the ice surface through the trapezoidal cross-section, thereby improving sliding stability and reducing resistance caused by embedding too deeply into the ice surface; the blade adopts an inverted bow-shaped streamlined arc edge, which can significantly reduce the air resistance caused by cutting the ice surface and increase the sliding speed. In addition, the quick-release blade holder utilizes the cooperation of a pull bolt, a locking rod, and a blade retraction bevel to overcome the disadvantage that traditional ice skates need to be pried out with the help of tools, thereby achieving quick disassembly and assembly, a simple structure, and convenient use.

Description

Technical Field

[0001] The present invention relates to the field of roller skate accessories, and in particular to a quick-release tool holder. Background Art

[0002] The ice blade is the core component of the skate, and its performance directly impacts a skater's speed, stability, and the quality of their technical execution. In sports like speed skating, figure skating, and ice hockey, high-quality blade design can significantly enhance performance. By reducing friction on the ice, blades enable athletes to glide efficiently while providing the necessary stability and balance for high-speed skating and complex maneuvers. Blade design is particularly crucial when performing challenging maneuvers like jumps, spins, sudden stops, and quick turns, directly determining the effectiveness of the technique and competitive performance.

[0003] Traditional ice skates mostly use a symmetrical thin-blade design that is parallel to the left and right. Although this design has a certain stability when skating, it exposes obvious limitations in difficult movements. In jumping movements, traditional ice skates have low take-off efficiency, and the impact force when landing is concentrated on the parallel blades, making it difficult to disperse the pressure and easily causing damage to the athlete's joints. When turning quickly, the parallel blades have insufficient contact area when the side tilt angle is large and cannot provide sufficient grip, which often causes the blades to slip, limiting flexibility and safety. In addition, during emergency stops, the parallel blades cannot fully cut into the ice surface, and the lack of friction leads to low stopping efficiency. At the same time, the center of gravity is unstable, increasing the risk of falling. These problems significantly limit the performance of athletes in competitions, especially in scenarios that require high flexibility and quick reactions, where traditional ice skate designs seem to be unable to cope.

[0004] In addition, with the advancement of skating technology and the increase in competition intensity, not only does the design of ice skates need to be optimized, but the rapid disassembly and assembly technology of ice skates has also become a research hotspot. This technology not only provides athletes with a convenient way to change equipment, but also significantly improves competition efficiency and safety. In high-intensity sports, ice skates may wear out or be accidentally damaged due to frequent use. At this time, timely replacement of ice skates is crucial for athletes. However, traditional ice skates are usually fixed with screws or buckles, and require the use of tools or cumbersome operating steps to complete the replacement, which obviously cannot meet the needs of racing against time in the game. Especially in ice hockey games, athletes wear heavy protective gear and protective gloves on their hands, which further increases the difficulty of traditional disassembly and assembly methods.

[0005] Currently, many quick-disassembly systems place the operating area at the rear end of the blade holder, using a paddle device installed in a small horizontal hole slot to achieve one-handed disassembly. Although this design simplifies the disassembly and assembly process in theory, in practice, thick gloves make it difficult to accurately insert the small hole slot to complete the operation. If athletes take off their protective gear to change, not only will they waste valuable time, but they may also affect their competition strategy due to failure to put it back in place in time. In addition, frequent removal of protective gear will also increase the risk of athletes' physical exposure during competition. Therefore, existing quick-disassembly technology still has considerable room for improvement in meeting actual combat needs.

[0006] In summary, existing ice skates and ice skate quick disassembly and assembly technologies need to be further optimized and improved to better meet the needs of modern ice skating. Summary of the Invention

[0007] The purpose of this invention is to provide a quick-release blade holder that can significantly improve sliding stability, smoothness and speed, while effectively reducing air resistance and ice friction, solving the problems of low sliding efficiency and inflexible operation of traditional ice skates, and having an efficient and convenient locking and unlocking mechanism, which significantly improves the convenience of disassembly and assembly of ice skates.

[0008] In order to achieve the above object, the present invention adopts the following scheme: a quick-release tool holder, comprising:

[0009] a blade body having a top and a bottom;

[0010] The hook parts are respectively arranged at intervals on the top of the blade body and are used to cooperate with the ice skate holder so that the blade body can be fixed on the ice skate holder;

[0011] A connecting rib, which is disposed between the two hook portions and has a tooth-like structure, helps to evenly distribute the impact force caused by movement, is used to enhance the stability of the connection between the blade body and the blade holder, and avoids vibration or deviation caused by a loose connection;

[0012] The blade, located at the bottom of the blade body, has a trapezoidal cross-section, making the bottom width of the blade in contact with the ice wider than the width of the blade body. This design increases the contact area between the bottom of the blade and the ice, better dissipating the impact force during sliding, enhancing grip and improving braking and steering efficiency. This design provides more stable support during high-intensity movements such as sudden stops, turns, or jumps, reducing the risk of falls;

[0013] The front and rear ends of the blade are wider than the center, and the left and right edges of the blade's bottom end are inversely arched to reduce air resistance during skating. By optimizing the blade shape, air flows more smoothly around the skate, reducing wind resistance during skating and thereby increasing skating speed and efficiency. This design can significantly improve the performance of athletes who need to skate at high speeds.

[0014] A knife support shell, which is used to connect to the sole of the shoe and has a cavity-like structure inside;

[0015] An operating area is formed by being recessed from the center of the tool holder housing, and a groove is provided at the bottom of the operating area and is communicated with the inner cavity of the tool holder housing;

[0016] A blade groove is recessed upward along the length direction of the bottom of the blade support shell and is used for inserting an ice skate;

[0017] A front hook locking groove is provided in one end of the blade groove and is used to lock one of the hook parts of the ice skate;

[0018] a rear hook locking groove, which is arranged in one end of the blade groove away from the front hook locking groove and is used to accommodate the other hook portion of the ice skate to be inserted;

[0019] A locking rod is disposed in the blade holder housing and can slide forward and backward. One end of the locking rod is provided with a hook end, which is used to hook the hook portion inserted into the rear hook lock groove when the locking rod moves forward, thereby locking and fixing the ice skate;

[0020] A pull bolt, which can be turned 90 degrees and connected to the end of the lock rod away from the hook end, and after being turned and folded into an upright state, passes through the slot and extends upward into the operating area;

[0021] When the pull bolt is manually pulled, the locking rod slides backward, releasing the locking of the hook end on the hook portion, thereby unlocking the ice skate and enabling it to be removed from the blade holder housing;

[0022] a first return spring, the first return spring being arranged behind the hooking end and being used to apply a return force to the locking rod after it moves backward, so that the locking rod returns to its initial position;

[0023] A first beveled surface is located on the front of the hook portion inserted into the rear hook lock slot. A second beveled surface is located on the hooked end, which cooperates with the first beveled surface to push the ice skate downward from the slot. During the unlocking operation, as the locking rod slides backward, the second beveled surface slides and compresses the first beveled surface, pushing the ice skate downward from the bottom of the slot. This sliding engagement utilizes the force of the inclined surfaces designed into the structure, allowing the initial release of the ice skate during the unlocking process, reducing resistance caused by ice chips or jamming, and making blade removal easier.

[0024] As a preferred solution of the present invention, the blade body, the blade portion, the hook portion and the connecting rib are integrally formed.

[0025] As a preferred embodiment of the present invention, the bottom surface of the blade portion that contacts the ice surface is in an arc shape with both ends tilted upward.

[0026] As a preferred embodiment of the present invention, the connecting rib includes a main tooth-shaped joint extending continuously along the length of the top of the blade. The continuity of the main tooth-shaped joint enhances the stability of the connecting rib, preventing loosening or misalignment between the blade and the blade holder during movement. This ensures that the blade is more firmly fixed to the blade holder, especially in high-speed and high-impact environments, and avoids operational errors or safety hazards caused by unstable connections. Auxiliary tooth-shaped joints are provided on the left and right sides of the main tooth-shaped joint, respectively. The auxiliary tooth-shaped joints are staggered with the main tooth-shaped joints and are lower in height than the main tooth-shaped joints. Through the staggered tooth-shaped joints, the connecting rib can effectively disperse the stress and impact forces caused by high-speed movement or intense movements at multiple contact points. The low height design of the auxiliary tooth-shaped joints not only helps reduce weight, making the overall structure more lightweight, but also optimizes the force transmission path, avoiding excessive wear or fracture at the connection caused by excessive concentrated stress. This structural design improves the strength and durability of the connecting rib, enhancing the long-term reliability of the ice skates during intense competition.

[0027] The above solution realizes the rapid disassembly and assembly of ice skates by setting an operating area and slots in the blade holder shell, combining the blade slot, front and rear hook lock slots, locking rod, hook end and pull bolt, so that athletes can quickly change ice skates without the help of tools or complicated operations. This convenient operation is particularly important for high-intensity competitions, especially in sports such as ice hockey, where athletes can quickly adapt to changing competition environments. Among them, the locking mechanism cooperates with the front and rear hook lock slots and the hook end of the locking rod to ensure that the ice skates are firmly fixed during use, resisting the impact force caused by intense exercise and enhancing the safety of ice skates during high-speed skating or intense exercise. At the same time, the first return spring design enables the locking rod to automatically reset, improving the smoothness of operation and the reliability of the system, and avoiding human operational errors.

[0028] As a further solution of the present invention, a pull bolt lock is provided at the end of the pull bolt, which can lock the pull bolt in the slot and prevent it from flipping upright, effectively preventing the pull bolt from accidentally loosening or flipping during sliding, and further ensuring operational safety.

[0029] As a preferred embodiment of the present invention, the pull-bolt lock includes a lock tongue groove provided at the end of the pull-bolt, the head end and the top end of the lock tongue groove are open, a lock tongue is retractably provided in the lock tongue groove, and the tail end of the lock tongue is provided with an elastic arm that can keep one end of the lock tongue extending out of the head end of the lock tongue groove. When the pull-bolt and the locking rod are in a straight line, the lock tongue is clamped on the inner wall of the tool holder shell at one end of the slot, and a safety device that can lock the lock tongue and prevent it from retracting into the lock tongue groove is provided on the top of the lock tongue. The design of the pull-bolt lock further enhances the safety and stability of the quick-release tool holder. The lock tongue groove and the retractable lock tongue allow the lock tongue to clamp one end of the slot in the tool holder shell during the pull-bolt operation, ensuring that the pull-bolt will not flip upright due to the looseness of the pull-bolt when not in use or in a sliding state, thereby causing the hook end to accidentally unlock the hook portion. The pull-bolt lock eliminates potential safety hazards associated with traditional blade removal methods, especially during high-intensity competitions when athletes are rapidly removing and installing skates. It effectively prevents blades from falling off or improper installation due to a loose lock, ensuring the blade removal system remains highly stable even during frequent operation. This allows the design to meet the need for rapid removal while ensuring safety and reliability during use.

[0030] As a further aspect of the present invention, the safety device includes a groove at the top of the lock tongue, with a pivoting plate hinged within the groove, one end of which can tilt upward and downward. A second return spring is provided on the bottom surface of the end of the rocker, remote from the hinge axis, to maintain the rocker in an upturned position. A limiting slope is provided on the sidewall of the groove, remote from the second return spring. The end of the rocker, remote from the second return spring, abuts against the limiting slope, allowing the tail end of the rocker to abut against the top opening of the lock tongue groove, thereby preventing the lock tongue from retracting into the groove. The design of the rocker and limiting slope ensures that the lock tongue remains in a stable locked position when not in operation, preventing the lock tongue from retracting into the groove and unlocking due to external vibration or unexpected forces, thereby ensuring the reliable connection between the skate and the blade holder. An extension arm is connected to the rocker, one end of which extends out of the groove and is connected to an operating button that can tilt the rocker downward. The operating button is located within the operating area. The addition of the extension arm and operating button makes the safety device more user-friendly. The operating button is located within the operating area, allowing the user to directly press it to trigger the rocker to flip down and unlock the lock tongue. This design ensures locking strength while maintaining the convenience of the unlocking process, providing users with a fast and safe operation experience. This innovative structure significantly enhances the functional integrity of the quick-release tool holder, making it suitable for applications requiring frequent disassembly and assembly and requiring high safety requirements.

[0031] Due to long-term skating on ice, ice debris can easily enter the gap between the ice blade and the blade groove, freezing the ice blade in the blade groove. Therefore, in actual use, it is often seen that when skaters remove the ice blade, they need to use a crowbar or screwdriver to pry up the ice blade after unlocking it before they can pull it out. As a further solution of the present invention, a sealing ring is detachably embedded in the blade groove and around the blade body. By providing a sealing ring in the blade groove and a detachable design of the sealing ring, it is convenient for users to clean, replace or maintain the sealing ring during use, ensuring the continued effectiveness of the sealing performance. This design improves the overall user experience of quick-release ice blades, allowing the unlocked ice blade to be easily pulled out, avoiding the embarrassment and inconvenience of using a crowbar or screwdriver to assist in disassembly due to ice debris in traditional quick-release structures. The bottom of the sealing ring is provided with a skirt extending outward along the bottom of the blade holder shell, forming an additional protective barrier to further prevent ice debris from entering the blade groove from the side. This double protection structure not only effectively deals with the problem of ice debris intrusion caused by high-speed friction or external environment during skating on ice, but also reduces the wear and tear on the blade groove and blade body surface caused by ice debris accumulation, thereby extending the service life of the ice blade and blade groove.

[0032] In summary, the present invention has the following beneficial effects compared to the prior art:

[0033] First, the present invention is particularly outstanding in its blade design, featuring a trapezoidal cross-section and a unique curved bottom edge, significantly improving skating performance and handling stability. The trapezoidal cross-section ensures that the bottom width of the blade, where it contacts the ice, is wider than the blade body. This design not only increases the force-bearing area, improving skating stability, but also effectively disperses pressure, reducing drag caused by the blade being too deeply embedded in the ice. This is particularly evident during high-intensity skating. Furthermore, the bottoms of the left and right sides of the blade feature curved edges, forming a streamlined, inverted arch. This design significantly reduces air resistance caused by cutting through the ice during skating, increasing skating speed while also reducing vibration during skating and enhancing smoothness and flexibility. In particular, in a design where the front and rear ends of the blade are slightly wider than the middle, the curved edges, combined with the trapezoidal cross-section, further optimize the stability of the skating trajectory, allowing the skater to more precisely control their movements when turning or accelerating. This comprehensive improvement solves the problems of insufficient stability and large air resistance caused by the single design of traditional ice skates when skating, making the present invention have significant advantages in both competitive skating and daily skating scenarios, greatly improving skating efficiency and comfort.

[0034] Secondly, the quick-release blade holder of the present invention overcomes the problem of traditional quick-release blades requiring additional tools to remove them, through the ingenious coordination of the pull bolt, locking rod, and blade release ramp. The rear hook lock slot and the interlocking end of the locking rod lock one of the hooks, ensuring secure and reliable installation and locking of the blade. The first and second blade release ramps cleverly coordinate to automatically push the blade downward during removal, eliminating the need for additional tools and significantly enhancing ease of installation and removal. The locking rod, combined with the first return spring, ensures automatic reset after unlocking, improving operational efficiency and user convenience. Furthermore, addressing the difficulty of removing traditional blades due to ice freezing in the blade slot, the present invention incorporates a sealing ring within the blade slot and adds a skirt structure to effectively prevent ice from entering the slot, significantly reducing the risk of freezing. The removable sealing ring not only facilitates cleaning and maintenance but also extends the life of the blade. It also optimizes the fit between the blade slot and the blade body, further enhancing the durability, reliability, and ease of use of the quick-release mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

Of course, these are merely examples or embodiments and are not intended to be limiting. Furthermore, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. Such repetition is for simplicity and clarity in describing the present invention and does not imply a specific relationship between the different embodiments and / or configurations discussed.

[0051] In addition, spatially related terms may be used, such as "below," "lower side," "from the inside out," "above," "upper side," and similar terms. These terms are used to facilitate the description of the relationship between one element or feature and another element or feature in the drawings. These spatially related terms include different orientations of the device in use or operation, as well as the orientations described in the drawings. The device may be turned to different orientations, rotated 90 degrees or other orientations, and the spatially related adjectives used therein may also be interpreted in the same way. Therefore, they cannot be understood as limiting the present invention. The terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features.

[0052] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: Figures 1 to 4 The quick-release blade holder shown in the figure includes a blade body 1 designed as a symmetrical, parallel, thin sheet. The blade body 1 has a top and a bottom. Two upwardly projecting hooks 3 are spaced apart on the top, front and back, of the blade body 1. These hooks 3 are used to engage with the ice skate holder, thereby securing the blade body 1 to the holder. The front hook 3 is a latch 3a extending obliquely forward from the top of the blade body 1, while the rear hook 3 is a hook 3b protruding upward from the top of the blade body 1. A tooth-like connecting rib 4 is provided on the top of the blade body 1 between the latch 3a and the hook 3b. This rib 4 includes a main tooth-shaped engagement portion 41 extending continuously along the length of the top of the blade body 1. Auxiliary tooth-shaped engagement portions 42 are provided on either side of the main tooth-shaped engagement portion 41. The auxiliary tooth-shaped engagement portions 42 are staggered with the main tooth-shaped engagement portion 41 and are lower in height than the main tooth-shaped engagement portion 41, thereby enhancing the stability of the connection between the blade body 1 and the ice skate holder. The blade portion 2 is connected to the bottom of the blade body 1. The bottom surface of the blade portion 2 in contact with the ice surface is in an arc shape with both ends tilted upwards. The width of the bottom surface of the blade portion 2 in contact with the ice surface is greater than the width of the blade body 1. Figure 3 As shown in FIG, the cross section of the blade portion 2 is trapezoidal. In this embodiment, the blade body 1 and the blade portion 2, the hook portion 3 and the connecting rib 4 are integrally formed. Figure 4As shown in the figure, the widths of the front and rear ends of the blade portion 2 are greater than the width of the central part, forming the left and right edges of the bottom ends of the blade portion 2 to be inversely arched to each other, that is, although the central part between the two wider ends of the blade portion 2 is also trapezoidal, the width is gradually narrower than that of the central parts at both ends. In addition to the two left and right edges of the bottom being inwardly concave inversely arched, the central waistline of the blade portion 2 is also inwardly concave inversely arched, which is beneficial to reducing the air resistance during sliding. The inversely arched curve makes the shape of the bottom edge of the blade portion 2 cutting the ice surface during sliding more in line with fluid mechanics, allowing the blade to better fit the ice surface during inclined turns, reducing the local friction resistance when the blade portion 2 contacts the ice surface and providing stronger grip, which not only improves the sliding speed, but also allows the skater to complete rapid turns or changes of direction more easily.

[0053] In addition, if Figures 5 to 14The figure also includes a knife support shell 5 for connecting to the sole of the shoe. The interior of the knife support shell 5 is a cavity-like structure. An operating area 50 is formed in the center of the knife support shell 5. Since the operating area 50 is in the center of the knife support shell 5, its size can be much larger than the hole grooves of similar quick-release mechanisms on the market. It is easy to perform actions in the operating area 50 while wearing gloves. A slot 54 is provided at the bottom of the operating area 50, which is connected to the inner cavity of the knife support shell 5. The slot 54 runs through the outer wall of the knife support shell 5 along the length of the knife support shell 5. An upwardly recessed knife groove 51 is provided along the length direction of the bottom of the knife support shell 5, and an ice skate can be inserted into the knife groove 51. To secure the ice skate blade within the blade slot 51, a tooth slot 55 is formed at the center top of the blade slot 51 to mate with the secondary toothed engagement portion 42 and the primary toothed engagement portion 41. A front hook lock slot 52 is provided at the front end of the blade slot 51 for inserting the hook 3a. In this embodiment, the front hook lock slot 52 communicates with the inner cavity of the blade holder housing 5. When the hook 3a is inserted into the front hook lock slot 52, the front end of the front hook lock slot 52 will lock the hook 3a, preventing it from moving downward. A rear hook lock slot 53 is provided at the rear end of the blade slot 51. The rear hook lock slot 53 is also connected to the inner cavity of the blade holder housing 5 and can accommodate the blade hook 3b. A guide slot 60 is provided from front to back within the blade holder housing 5. A locking rod 6 is movably inserted into the guide slot 60 and can slide back and forth along the guide slot 60. A hooking end 61 is provided at the rear end of the locking rod 6. The hooking end 61 is shaped like a hook with its opening facing downward, and is used to hook the blade hook 3b inserted into the rear hook locking slot 53. A first return spring 64 is provided behind the hooking end 61. The tip of the blade hook 3b is inclined. When the blade hook 3b is inserted into the rear hook locking slot 53, the inclined surface of the blade hook 3b squeezes the hook head of the hooking end 61 backward, thereby causing the entire locking rod 6 to move backward. When the hook head of the blade hook 3b passes the hook head of the hooking end 61, the first return spring 64 applies a return force to the hooking end 61, causing the hooking end 61 to move forward and hook the blade hook 3b. Simultaneously, the locking rod 6 returns to its initial position, thereby locking the ice skate in place with the rear hook locking slot 53. To unlock the hook 3b, the locking rod 6 is moved backward again, allowing the hook end 61 to release the hook 3b again. To facilitate the backward movement of the locking rod 6, a pull bolt 62 is hingedly connected to the end of the locking rod 6, away from the hook end 61. This pull bolt 62 can be tilted upward 90 degrees to an upright position. A torsion spring 67 is attached to the hinge axis of the pull bolt 62 to maintain the pull bolt 62 in the upright position. As can be clearly seen in the figure, when the pull bolt 62 is tilted and folded into the upright position, it extends upward through the slot 54 into the operating area 50. The end of the pull bolt 62 at the hinged joint abuts against the end of the locking rod 6, facilitating the backward movement of the locking rod 6. During use, the upright pull bolt 62 is manually pulled backward, causing the locking rod 6 to slide backward, releasing the lock of the hook end 61 from the hook 3b.A first blade-retracting bevel 31 is provided on the front side of the hook 3b inserted into the rear hook lock slot 53. A second blade-retracting bevel 66 is provided on the hooking end 61, which cooperates with the first blade-retracting bevel 31 to push the ice skate downward and out of the blade slot 51. Once the hooking end 61 is released from the hook 3b, the pull bolt 62 is pulled rearward. The first blade-retracting bevel 31 on the hooking end 61 pushes against the second blade-retracting bevel 66 on the back of the hook 3b, allowing the rear end of the blade body 1 to move downward from the blade slot 51. The operator can then conveniently pull the entire ice skate out of the blade slot 51 and remove it from the blade holder housing 5.

[0054] During skating, the friction between the ice blade and the ice surface produces a large amount of tiny ice chips. These ice chips enter the gaps and accumulate under the action of sliding pressure. In addition, due to the influence of thermal expansion and contraction, the ice blades heat up due to friction, and the ice chips quickly freeze in the low-temperature environment, further tightening the gaps. As a result, it becomes difficult to pull out the ice blades after a long period of skating. It is necessary to use tools such as crowbars to forcibly pry them out, which is not only time-consuming and labor-intensive, but may also damage the connection structure between the ice blade and the blade groove, reducing the service life of the ice skates. Therefore, the present invention has a sealing ring 9 that is detachably embedded in the blade groove 51 and around the blade body 1. The bottom of the sealing ring 9 is provided with a skirt 91 that extends outward along the bottom of the blade support housing 5. The detachable sealing ring 9 in the blade groove and the outwardly extending skirt 91 design effectively prevents ice chips from entering the gap between the blade body 1 and the blade groove 51, making it convenient for users to clean, replace or maintain the blade groove 51 and the sealing ring 9 during use, ensuring the continued effectiveness of the sealing performance. This design improves the overall user experience of the quick-release ice skates, making it easy to pull out the unlocked ice skates, and avoiding the embarrassment and inconvenience of using a crowbar or screwdriver to assist in disassembly due to ice jams in traditional quick-release structures. In addition, in order to facilitate the disengagement of the sealing ring 9 from the knife groove 51, a triangular block 92 extending upward and bypassing the top of the blade body 1 is provided at the top of the sealing ring 9. The tail end of the hook end 61 is also a bevel. When the second knife-retracting bevel 66 squeezes the knife hook 3b downward, the tail end of the hook end 61 will simultaneously squeeze the triangular block 92, allowing the sealing ring 9 to disengage from the knife groove 51. It should be noted that in order to prevent the sealing ring 9 from disengaging from the knife groove 51 during sliding, a hanging ring 93 bypassing the top of the blade body 1 is provided at the top of the sealing ring 9 corresponding to the front hook lock groove 52. It should also be noted that in this embodiment, to prevent foreign objects or ice from entering slot 54, a cover plate 68 having the same shape as slot 54 is provided on top of locking rod 6. When locking rod 6 is in the initial position, cover plate 68 is inserted into slot 54 behind pull pin 62, thereby sealing off this portion of slot 54.

[0055] When the top end of the blade body 1 is inserted into the blade groove 51 and the hook end 61 is hooked to lock the blade hook 3b, that is, when the ice skate is completely installed on the blade holder housing 5, the pull bolt 62 is turned over to be in a straight line with the locking rod 6, in order to prevent the pull bolt 62 from being accidentally loosened or turned over during sliding, Figures 7 to 14As shown, a pull bolt lock buckle 7 is provided at the end of the pull bolt 62, which can lock the pull bolt 62 in the slot 54 and prevent it from flipping and standing upright.
