the linkage shaft 602 is arranged inside the movable block 601, is movably connected with the movable block 601, and is in contact with the extrusion roller 3;
a transmission shaft 603 movably connected to the movable block 601 and extending into the movable groove 4;
the two driving wheels 604 are respectively and fixedly connected with the linkage shaft 602 and the transmission shaft 603 and are contacted with each other, and the driving wheel 604 close to one side of the squeezing roller 3 is contacted with the squeezing roller 3;
the transmission mechanism 6 plays a role in friction force transmission, the basic principle of the transmission mechanism is consistent with the principle of friction wheel transmission, and the transmission mechanism can be known as mature prior art;
when the squeezing roller 3 rotates, the driving wheel 604 is driven to rotate, and at the moment, the transmission shaft 603 is driven to rotate by the driving wheel 604;
because the outer surfaces of the squeezing roller 3 and the two transmission wheels 604 are in contact, the rotation direction can be changed in the transmission process, the rotation direction of the transmission wheel 604 in contact with the squeezing roller 3 is opposite to that of the squeezing roller 3, the rotation direction of the transmission wheel 604 outside the transmission shaft 603 is consistent with that of the squeezing roller 3, and the direction of the friction force of the roller wheel is opposite to that of the rotation of the roller wheel, so that the bicycle moves forwards by means of the friction force when a reverse friction force is applied to the outer ring of the mounting bearing 2 by the transmission wheel 604, and the rotation direction of the tire is opposite to that of the bicycle body in the process;
the inner ring of the mounting bearing 2 and the extrusion roller 3 rotate in the same direction, so that the rotating direction of the ball inside the mounting bearing 2 is opposite to that of the extrusion roller 3, and the ball generates friction force with the extrusion roller 3 when rotating, so that the ball performs circular motion, and in the process, because the inner wall of the outer ring of the mounting bearing 2 is in contact with the outer surface of the ball, and the outer ring of the mounting bearing 2 is kept relatively fixed, the friction force applied to the outer ring of the mounting bearing 2 is the same as the rotating direction of the extrusion roller 3;
at the moment, the outer ring of the mounting bearing 2 is subjected to forces in different directions, and the sum of the external forces applied to the outer ring of the mounting bearing 2 is smaller than a single force, so that the mounting bearing 2 cannot move relative to the base block 1;
preferably, the movable block 601 is composed of a hollow rectangular block and a limit block, wherein:
a hollow rectangular block provided on the front side of the base block 1;
the two limiting blocks are fixedly connected with the hollow rectangular block and extend into the limiting baffle 5;

one end of the pressure spring 702 is fixedly connected with the connecting frame 701, and the other end of the pressure spring is fixedly connected with the inner side wall of the movable groove 4;
the linkage wheel 703 is fixedly connected with the transmission shaft 603 and is contacted with the mounting bearing 2;
on one hand, the pressure mechanism 7 provides pressure to enable the driving wheel 604 to be tightly attached to the squeezing roller 3, and because the surface of the driving wheel 604 is a rubber surface, the driving wheel is tightly attached to the squeezing roller 3, and meanwhile, the interaction force between the linkage wheel 703 and the outer ring of the mounting bearing 2 is very small, so that the friction force generated when the linkage wheel 703 moves is also very small;
on the other hand, when the mounting bearing 2 moves along with the extrusion roller 3, the mounting bearing strikes the linkage wheel 703, so that the pressure spring 702 is stressed and compressed to play a role in buffering.
The working principle is as follows:
when the squeeze roll 3 rotates, the squeeze roll drives the driving wheels 604 to rotate, the transmission shaft 603 rotates under the action of the driving wheels 604, so as to drive the linkage wheel 703 to rotate, the two driving wheels 604 are driven by friction force (the specific principle refers to friction wheel transmission), and the squeeze roll 3 and the two driving wheels 604 are driven by friction force, so that the rotating direction of the driving wheels 604 outside the transmission shaft 603 is opposite to the rotating direction of the squeeze roll 3;
because the inner ring of the mounting bearing 2 moves along with the squeeze roll 3, the rotating direction of the ball inside the mounting bearing 2 is opposite to that of the squeeze roll 3, and at the moment, the position of the outer ring of the mounting bearing 2 is relatively fixed under the action of the base block 1, so that the ball inside the mounting bearing 2 rotates and moves circularly relative to the outer ring of the mounting bearing 2, the mounting bearing 2 is subjected to the friction force opposite to the circular motion of the ball, and the outer ring of the mounting bearing 2 and a bearing seat generate relative displacement under normal conditions, namely caused by the friction force;
at this time, the force applied to the outer ring of the mounting bearing 2 by the linkage wheel 703 driven by the transmission shaft 603 is opposite to the force applied to the outer ring of the mounting bearing 2 by the balls (the transmission of the force is performed by using friction force, which is a mature prior art, and the content and stress analysis of the force can be known by a hundred-degree friction wheel, so that the description is omitted here), so that the total external force applied to the mounting bearing 2 is reduced, and the relative motion between the outer ring of the mounting bearing 2 and the base block 1 is avoided, thereby reducing the wear degree;
the pressure spring 702 provides elasticity, at the moment, the pressure spring 702 is in a compression state, so that the driving wheel 604 is tightly attached to the squeezing roller 3, the surface of the driving wheel 604 is a rubber surface, the driving wheel 604 is tightly attached to the squeezing roller 3, and the interaction force between the linkage wheel 703 and the outer ring of the mounting bearing 2 is small, so that the situation that the outer ring of the mounting bearing 2 is driven to move by the linkage wheel 703 cannot occur;
the pressure mechanism 7 herein not only provides the pressure, but also retains the function of the elastic support structure in the patent, so that the buffer function in the patent can still be realized, and the structure is improved on the basis of the patent, therefore the buffer function therein is not described in detail.
