[0002] Speed skating is an ice sport. Engaging in speed skating helps to improve physical and mental health, promote human metabolism, enhance cardiopulmonary function, strengthen cold resistance ability, and cultivate a firm and tenacious will quality. When in use, a person installs skate blades on the speed skates, and at the same time, the user's legs push, and the speed skates slide on the ice surface.

[0003] Skating, as a fierce ice sport, the wear of skate blades, especially the change in curvature, has a great impact on skating. Especially for professional athletes, in competitions, in order to maintain adhesion on the ice and sliding speed, the blades of the skate blades need to be replaced at any time. It is very important to grind the worn blades to maintain the curvature of the blades.

[0004] Currently, when a person replaces the skate blades, the skate blades are fixed to the ice skates by screws. When replacement is needed, the whole needs to be replaced, which will cause the person to consume a long time for replacement; at the same time, during training, the person cannot stand firm after use, which will cause the person to fall frequently; and when in use, ice will adhere to the skate blades, resulting in a large resistance when the skate blades are used. At the same time, when falling, the skate blades will cause harm to the person. Summary of the Invention

[0017] Working principle: During installation, the ice skate blade bracket is fixed to the lower end of the shoe cover through bolts. Then, when the user is using it, the detector two located at the right end of the ice skate blade bracket will detect the distance after detachment between the ice surface and the ice skate blade body. Subsequently, through electrical connection, the detected data will be transmitted into the controller. Then, in cooperation with the controller and the gasket, the gasket can be activated. Subsequently, the gasket will drive the second rotating rod and the sliding rod to expand and contract up and down. While expanding and contracting up and down, through the linkage of the linkage plate, it will drive the first rotating rod to expand and contract up and down together. While expanding and contracting, it will drive the first fixing rod, the first fixing block, and the first clamping block to clamp different positioning plates, enabling the user to quickly replace the ice skate blade body. At the same time, when the user falls, the ice skate blade body can be quickly retracted. Subsequently, the motors at both outer ends of the ice skate blade body drive the third rotating rod to push up and down. While pushing, it will drive the threaded rod to rotate in the third fixing block. While the threaded rod rotates, it will drive the first gear to rotate together. Under the rotation of the first gear, the first rack connected to it through meshing can move left and right. Immediately, the first rack will drive the slider to slide on the chute, enabling it to drive the cleaning block to clean the ice attached to the ice skate blade body with gas, reducing the situation that the ice skate blade body cannot be cleaned manually during long-term use and reducing the occurrence of falling. When the user stops sliding, when the user needs to stop, the detector one will detect the user's activity level. Subsequently, the detector one will drive the rotating column in the fourth fixing block to open. And during use, the second rack will drive the stabilizing plate to support the ice surface. Then, the rotating column will drive the second gear to rotate. At the same time, when the second gear rotates, it will drive the first rotating disk to rotate together. Subsequently, it will drive the first limiting block to engage with the second rack, enabling it to be engaged, facilitating the user to use it quickly and providing better support.

[0018] The present invention provides a safety type speed skating skate blade based on tip ice shoveling and drag reduction. It has the following

[0019] Beneficial effects:

[0020] 1. When the distance between the ice surface and the ice skate blade is too large, the detector one in the support structure can detect it. Then, the rotating column drives the rotating disk to rotate. Under the rotation of the rotating disk, the first limiting block is driven to successfully engage with the second rack, enabling it to reduce the sliding speed of the second rack. Subsequently, the stabilizing plate located at the lower end of the second rack is fixed on the ice surface, which can provide auxiliary support when the user stops moving and can also provide auxiliary support when the user is practicing for the first time.

[0021] 2. The present invention can detect the distance between the ice surface and the ice skate bracket through the second detector, enabling it to drive the gasket to start. Subsequently, the second rotating rod at the lower end of the gasket will extend and retract up and down through the sliding rod on the linkage plate. Then, due to the linkage property of the linkage plate, it will drive the clamping blocks on the left and right sides at the lower end of the chuck to clamp different clamping plates. Subsequently, the clamping plates will drive the ice skate body to move up and down, enabling the gasket to retract the ice skate body when a person slips. Then, it will be protected by the protective plate, thereby reducing the injury to the person caused by the ice skate body and increasing the service life of the ice skate body at the same time.

[0022] 3. When the ice skate body is in use, the present invention can start the motor while detecting the ice surface through the second detector. Subsequently, the motor will drive the third rotating rod to move up and down. Then, it can drive the threaded rod to slide in the third fixed block. Subsequently, it can drive the first gear to rotate together. Through the cooperation of the first gear and the first rack, it can drive the sliding groove at the upper end of the first rack to slide. Then, it can drive the cleaning block to clean the ice cubes attached to the ice skate body, reducing the ice cubes attached to the ice skate body for a long time and improving the usability for the person.
