Description

Technical Field

[0001] The utility model relates to the technical field of card reader magnetic heads, in particular to a fixing device for fixing a card reader magnetic head. Background Technique

[0002] A card reader is abbreviated as a POS terminal. The terminal first sends information to the UnionPay platform by means of dialing through a telephone line. After the UnionPay platform identifies the relevant information, it will send the deduction information to the issuing bank. After the issuing bank confirms it, it will send the information back to the UnionPay platform. After the UnionPay confirms it, it will send the processed information to the front-end terminal again. After the terminal receives the confirmed information, it will print the receipt. The magnetic head refers to a component that reads data on a magnetic medium through the magnetic principle and is one of the essential components of a card reader. During the production and processing of the magnetic head, it is usually necessary to fix the magnetic head through a fixing device.

[0003] During the process of fixing the magnetic head with the fixing device, it is usually to drive the pressing plate to descend and press and fix the magnetic head through the pressing plate. However, during this process, usually only one group of magnetic heads can be fixed. When multiple groups of magnetic heads need to be fixed, multiple groups of fixing devices need to be used, which is more cumbersome to use. At the same time, the pressing plate is usually fixedly arranged and cannot be replaced according to specific usage requirements, which is not convenient for the use of the fixing device.
