Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 The utility model provides a technical solution: a continuously variable transmission, including a base 1, a mounting hole 2, a continuously variable transmission body 3, a rubber shock-absorbing pad 4, a fixing rod 5, a limiting ring 6, a silencer cover 7, a limit block 8, a silencer plate 9, a front groove 10, a rear groove 11, a temperature sensor 12, a controller 13, an exhaust fan 14, a protective plate 15, a ventilation slot 16 and a ventilation cavity 17. When using the continuously variable transmission, if Figure 1 , Figure 3 and Figure 4First, the base 1 can be placed at the position where the continuously variable transmission is to be used, and then screws can be installed through the mounting holes 2 symmetrically opened inside the outer end of the base 1 to install and fix the base 1. Then, the continuously variable transmission body 3 can be placed above the base 1, so that the outer end of the continuously variable transmission body 3 is nested outside the fixing rod 5 fixedly connected to the base 1, and the continuously variable transmission body 3 is attached to the rubber shock-absorbing pad 4 nested outside the lower end of the fixing rod 5. Then, the limiting ring 6 can be threadedly connected to the outer side of the upper end of the fixing rod 5 until the limiting ring 6 is attached to the continuously variable transmission body 3, so as to achieve the purpose of limiting the continuously variable transmission body 3;

[0025] like Figure 1 , Figure 2 and Figure 3 , during the use of the continuously variable transmission, the transmission shaft can be connected and positioned with the continuously variable transmission body 3, and then the tools can be taken from the front groove 10 and the rear groove 11 opened inside the front and rear ends of the base 1 to check the tightness of the continuously variable transmission parts to avoid looseness, and then the continuously variable transmission body 3 can be operated to transmit the transmission shaft. During the operation of the continuously variable transmission body 3, the rubber shock-absorbing pad 4 fitted under the continuously variable transmission body 3 is convenient for shock-absorbing the continuously variable transmission body 3 under the elastic performance of the rubber shock-absorbing pad 4 itself, and the silencer cover 7 can be nested on the outside of the continuously variable transmission body 3, so that the limit block 8 fixedly connected under the silencer cover 7 is nested and engaged with the base 1, and the silencer cover 7 is fitted to the outside of the silencer plate 9 fixedly connected to the upper left end of the base 1, so that the silencer cover 7 and the silencer plate 9 are shielded and silenced by their own silencer performance, and the continuously variable transmission body 3 is shielded and silenced, thereby improving the quality of the working environment;

[0026] like Figure 1 and Figure 3 , and a controller 13 that can be embedded and installed on the inner side of the right rear upper end of the base 1, controls the temperature sensor 12 embedded and installed in the base 1 in front of the controller 13, and cooperates with the exhaust fan 14 fixedly installed on the inner side of the right end of the base 1.

Therefore, after the temperature sensor 12 senses that the temperature inside the base 1, the silencer cover 7 and the silencer plate 9 is too high, the controller 13 can control the exhaust fan 14 to operate, so that the outside air enters the base 1, the silencer cover 7 and the silencer plate 9 through the ventilation cavity 17, and then passes out through the protective plate 15 and the ventilation slot 16, so as to facilitate the ventilation and heat dissipation of the continuously variable transmission body 3 and prolong its service life;
