When the first groove 3101 is engaged with the fixing post 32, the elastic force adjusting mechanism of the embodiment adjusts the elastic force of the elastic rope by taking the reduction of the elastic force as an example:
when a user presses the adjusting button 210 on the adjusting handle 21, the clamping portion 2110 slides upwards in the sliding slot 220, and meanwhile, the adjusting plate 22 is pressed downwards through the action of the adjusting handle 21, so that the adjusting plate 22 moves towards a direction close to the second groove 3102;
in the process that the adjusting plate 22 moves towards the direction close to the second groove 3102, the fixing column 32 and the first reel 11 are driven to move downwards, that is, the fixing column 32 moves towards the direction close to the second groove 3102, and the first reel 11 moves towards the direction close to the second reel 12;
during the process that the adjusting plate 22 moves towards the direction close to the second groove 3102, the spring 330 is extended, and the telescopic rod 24 is shortened;
when the fixing column 32 moves to the second groove 3102, the acting force on the adjusting key 210 and the adjusting plate 22 is cancelled, so that the fixing column 32 is clamped at the second groove 3102, and meanwhile, the sliding of the fixing column 32 can be limited by the pulling force of the spring 330 on the fixing column 32, so that the fixing column 32 and the second groove 3102 are fixed; namely, the adjustment from the first gear to the second gear is realized;
after the fixing column 32 is fixed with the second groove 3102, the distance between the first reel 11 and the second reel 12 is reduced compared to before the adjustment, so that the elastic force of the elastic cord is reduced.
In the same way, the adjusting plate 22 is lifted upwards under the action of the adjusting handle 21, so that the adjustment from the second gear to the first gear can be realized, namely the elasticity of the elastic rope is increased.
By the same principle, the adjustment from the first gear to the third gear or the fourth gear can be realized, and the adjustment from the fourth gear to the third gear and the adjustment from the third gear to the second gear can also be realized.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention.
