[0007] 1. In this utility model, the side plate of the sliding plate is inserted into the side strip-shaped sliding hole, which positions the side sliding plate and fixes its height on the mounting housing. The symmetrical side sliding plates are located in the upper middle position of the side of the mounting housing, which can stably clamp the RFID card writer during use. The lower sliding plate is inserted into the lower strip-shaped sliding hole, which positions the lower sliding plate horizontally. One end of the symmetrical side sliding plate and the lower sliding plate are placed inside the mounting housing, and the two are connected inside the mounting housing to ensure the simplicity of the outer tube of the device. The fixing block is installed and fixed inside the mounting housing. The guide slide rod passes through the fixing block, and the fixing block positions the guide slide rod, causing the guide slide rod to move vertically, thereby causing the middle push plate to slide vertically. When the middle push plate slides vertically, it drives... The lower sliding plate slides up and down. The rotating connecting plate is connected to the slide plate via the second connecting shaft. The connecting plate step plate is connected to the upper push plate via the third connecting shaft. The upper part of the middle push plate is connected to the side of the side sliding plate through the two ends of the rotating connecting plate. The symmetrical side sliding plate, rotating connecting plate, lower sliding plate and middle push plate form a linkage mechanism. When the RFID card writer is in use, the RFID card writer is placed in front of the mounting housing and falls naturally. Under the pressure of the RFID card writer, the lower sliding plate slides down, which in turn causes the middle push plate to drive the symmetrical rotating connecting plate to rotate. The symmetrical rotating connecting plate rotates towards each other and moves downward at the same time, which in turn drives the symmetrical side sliding plates to move towards each other at the same time. The symmetrical slide plate side plates clamp the upper part of the RFID card writer.
[0008] 2. The lower plate of this utility model supports the lower part of the RFID card writer. A spring is sleeved on the guide slide rod. In the natural state of use, the spring applies an upward pushing force to the push plate protrusion, causing the middle push plate to push the symmetrical rotating connecting plate and drive the symmetrical sliding plate side plates to open outwards at the same time. At this time, the lower sliding plate is in an upward state, which facilitates the clamping and insertion of the RFID card writer. When the RFID card writer is inserted into the device, the symmetrical sliding plate side plates cooperate with the lower plate to clamp the RFID card writer under the action of gravity. When it is necessary to remove the RFID card writer, simply lift the RFID card writer upwards. This device is small in size, can be used one-to-one with the card writer, is easy to operate, and is convenient to carry and fix the RFID card writer. When using this device, simply stick the mounting shell to the wall with adhesive. Attached Figure Description
