(2).维基词典 pulley lever

One of the simple machines; a wheel with a grooved rim in which a pulled rope or chain will lift an object (more useful when two or more pulleys are used together, as in a block and tackle arrangement, such that a small force moving through a greater distance can exert a larger force through a smaller distance).

To raise or lift by means of a pulley.

A crowbar.

A rigid piece which is capable of turning about one point, or axis (the fulcrum), and in which are two or more other points where forces are applied; — used for transmitting and modifying force and motion.

A small such piece to trigger or control a mechanical device (like a button).

A bar, as a capstan bar, applied to a rotatory piece to turn it.

An arm on a rock shaft, to give motion to the shaft or to obtain motion from it.

A levee.

To lever.

To lever (physically).

To lever (in an abstract sense).

To increase the share of debt in the capitalization of a business.

Rather.

(3).牛津词典 pulley lever

a wheel with a grooved rim around which a cord passes, which acts to change the direction of a force applied to the cord and is used to raise heavy weights.

a wheel or drum fixed on a shaft and turned by a belt, used for the application or transmission of power.

hoist with a pulley

a rigid bar resting on a pivot, used to move a heavy or firmly fixed load with one end when pressure is applied to the other

a projecting arm or handle that is moved to operate a mechanism

a means of pressurizing someone into doing something

lift or move with a lever

move (someone or something) with a concerted physical effort

use a lever

pressurize (someone) to do something

(4).韦伯斯特词典 pulley lever

A wheel with a broad rim, or grooved rim, for transmitting power from, or imparting power to, the different parts of machinery, or for changing the direction of motion, by means of a belt, cord, rope, or chain.

To raise or lift by means of a pulley.

More agreeable; more pleasing.

Rather.

A rigid piece which is capable of turning about one point, or axis (the fulcrum), and in which are two or more other points where forces are applied; - used for transmitting and modifying force and motion. Specif., a bar of metal, wood, or other rigid substance, used to exert a pressure, or sustain a weight, at one point of its length, by receiving a force or power at a second, and turning at a third on a fixed point called a fulcrum. It is usually named as the first of the six mechanical powers, and is of three kinds, according as either the fulcrum F, the weight W, or the power P, respectively, is situated between the other two, as in the figures.

A bar, as a capstan bar, applied to a rotatory piece to turn it.
