What is a monkey key?

The key of the monkeys is the type of manual key of the adjustable size that was heavily used during the 19th century. Since then, this key style has lost the soil on a more compact crescent key and an easier screwed tubular key. What the use of the tool fell out of kindness, this term began to apply to its exchange and keys adapting the size. The original monkey key was used for many tasks, from assembly to industrial production.

The design of the monkey key was very simple. A solid metal piece forms a handle, slipping and upper jaw keys. The screw sits on the front of the device and is partially screwed into the lower jaw. The lower jaw slips up and down the sliding part of the handle when the screw rotates. This design allows the user to adjust the size of the jaw that opens at the right angle to the handle, turning the bolt with the thumb. Most handles of worries or welded together, except for the upper jaw. The screw sits on the top of the metal column in the handle; This allows him to freely withto move, but not to go. The lower jaw is slipped onto the slide, where the screw is attached to the hole in the underside of the jaw. Then the upper jaw is welded to the handle and prevents the key to constantly crumble.

Monkey Wrench quickly lost the soil to other tools during the 20th century. This tool was directly replaced by a crescent key. The postal key has a much smaller head and thinner construction. This allows him to fit into smaller areas, but still performs the same tasks.

The monkey key construction was accepted by a tubular key. The main difference between the two tools is in the jaws. The key to the monkey has smooth jaws such as the crescent key that was used to grasp the nuts. The pipe pipes have grooved jaws, which gives him a tube to hold the pipe. This small difference makes the basic design two separate tools.

There is some debate about the origin of the concept of a monkey key. One of the common teorie je, že se jedná o derivát jména jeho původního tvůrce Charlese Monckyho. Ostatní lidé uvádějí, že se jedná o odkaz na to, jak se čelisti scházejí; Vypadají jako obyčejná opice.
