Safety charger

Abstract

The invention discloses a safety charger which comprises a charging head and a data wire head matched with the charging head, wherein a socket is formed at the bottom of the charging head; a groove isformed at the top of the socket in a communication manner; fixing grooves are symmetrically formed at the right and the left of the socket in a communication manner; extension slide grooves are formed on the outer sides of the fixing grooves in a communication manner; transmission cavities are arranged on the outer sides of the extension slide grooves; first bevel gears are arranged in the transmission cavities; extension threaded rods are fixedly arranged on the inner side faces of the first bevel gears and extend to the inner sides into the extension slide grooves; and extension slide blocks are connected with the extension threaded rods in a threaded fit manner. The charger is simple in structure and convenient to use; the data wire head is stably matched with the socket of the charging head in a splicing manner to avoid charging suspension due to looseness; internal power cutoff is achieved when the data wire head is pulled out; and sparks and electric shock accidents are avoided.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a safe charger. Background technique [0002] The charger is a device for charging other electrical appliances. It adopts high-frequency power supply technology and uses advanced intelligent dynamic adjustment charging technology. It is widely used in various fields, especially in the field of life.
