[0002] As we all know, when using a lever, in order to save effort, you should use a lever with a longer power arm than the resistance arm; if you want to save distance, you should use a lever with a shorter power arm than the resistance arm. Therefore, using a lever can save effort and distance. However, if you want to save effort, you must move more distance; if you want to move less distance, you must spend more effort. It is impossible to save effort and move less distance. In addition, we often see something called a wheel axle. In fact, the wheel axle is also an application of a lever. In order to change the wheel axle speed instantly, we often use a torque adjustment device to achieve it.

[0018] The present invention is further described in detail below in conjunction with embodiments and drawings:

[0019] See Figure 1 , Figure 2 , Figure 3The first embodiment of the axle-type continuously variable torque converter of the present invention is shown. It includes a first power arm 1 and a second power arm 2. The first power arm 1 extends from its first base 11, and the second power arm 2 extends from its second base 21. The first base 11 and the second base 21 are respectively hinged on a fixed shaft 10, that is, the first power arm 1 and the second power arm 2 are both fixed on the fixed shaft 10 and can rotate independently around the fixed shaft 10 without affecting each other. An adjustment guide rail 4 is provided between the first power arm 1 and the second power arm 2. The adjustment guide rail 4 is fixed on the first power arm 1. In this embodiment, the adjustment guide rail 4 is a cylindrical polished rod. Of course, the adjustment guide rail 4 can also be a slide rail or the like. A slider device 3 is also provided between the first power arm 1 and the second power arm 2. The slider device 3 includes an upper slide plate 31 and a lower slide plate 32, and also includes a vertical plate 33. The slider device 3 is fixed to an adjustment rail 4 through the vertical plate 33, and can move along the adjustment rail 4 in cooperation with the adjustment rail 4. The slider device 3 is clamped on the first power arm 1 and the second power arm 2 through the upper slide plate 31 and the lower slide plate 32. A coaxial and corotating resistance arm 5 is externally connected to the side of the second power arm 2 on the second base 21, which is regarded as a rotating wheel in the figure of this embodiment. In this way, when the first power arm 1 is rotated by the handle 12, the second power arm 2 moves integrally with the first power arm 1 due to the action of the slider device 3, and the force point of the second power arm 2 rotation is located at the contact point between the upper slide plate 31 or the lower slide plate 32 and the second power arm 2. When the slider device 3 is moved by a person to change its position, the force point of the second power arm 2 rotation also changes accordingly. That is, when the slider device 3 changes the moving position of the first power arm 1 and the second power arm 2, the torque of the second power arm 2 changes. At this time, when the torque of the first power arm 1 remains unchanged, the resistance arm 5 connected to the second power arm 2 and rotating coaxially can output the required speed or output the required force as needed.

[0020] See Figure 4 The figure shows the second embodiment of the axle-type continuously variable torque converter of the present invention. Different from the first embodiment, the adjusting guide rail 4 of the present embodiment is a screw rod 42, which is connected and fixed to the fixing seat 13 through a bearing, and the fixing seat 13 is fixed on the first power arm 1. The vertical plate 33 is provided with a threaded hole and is fixed and movable with the screw rod 42 through the threaded hole, and the upper slide plate 31 and the lower slide plate 32 are respectively fixed on the vertical plate 33; the upper slide plate 31 and the lower slide plate 32 clamp the first power arm 1 and the second power arm 2 and can move along the first power arm 1 and the second power arm 2. The adjuster 41 is a screw knob 411, which is arranged at the end of the screw rod 42, and the screw knob 411 is rotated to rotate the screw rod to drive the slider device 3 to move.

[0021] See Figure 5The third embodiment of the axle-type stepless torque converter of the present invention is shown. Different from the second embodiment, the adjustment guide rail 4 of this embodiment is also a screw 42, and the adjuster 41 is an umbrella wheel assembly, which is arranged in the base hole 111 of the first base 11 and cooperates with the screw 42. The screw is rotated by rotating the umbrella wheel knob 412 to drive the slider device 3 to move.

[0022] See Figure 6 The fourth embodiment of the axle-type continuously variable torque converter of the present invention is shown. Different from the single slider devices of the first, second and third embodiments, this embodiment is a double slider device. It is composed of a first slider device 3-1 and a second slider device 3-2. A symmetrical left first power arm 1-1 and a right first power arm 1-2 are extended from the first base 11, and a symmetrical left second power arm and a right second power arm are extended from the second base 21. The first slider device 3-1 and the second slider device 3-2 are symmetrically arranged at the midpoint of the screw rod 42, and the screw rod 42 is provided with positive and negative threads respectively with the midpoint as the boundary. In this way, when the screw rod 42 is rotated by the knob, the first slider device 3-1 and the second slider device 3-2 will move toward each other. The purpose of setting the first slider device 3-1 and the second slider device 3-2 in this embodiment is to reduce the force on the upper and lower slides in the slider device, so that the upper and lower slides have a longer service life.

[0023] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
