The cash register 102 and the thermal printer body 103 are both provided with a USB interface 104, and also include a storage component arranged on the support platform 101 for connecting and storing redundant USB data cables;

[0022] The storage assembly includes a mounting plate 201 fixedly connected to the support platform 101, the mounting plate 201 is located between the cash register 102 and the thermal printer body 103, and is located in the middle of the two. A spiral storage groove 202 is provided on the side of the mounting plate 201 away from the support platform 101, and a through hole 203 is provided on the side of the mounting plate 201 close to the USB interface 104. The mounting plate 201 is provided with a driving assembly for driving the USB cable;

[0023] It should be noted here that: by setting up the storage component, the redundant USB data cables piled up on the bracket platform 101 can be stored, thereby avoiding the long data cables from falling off or being damaged due to entanglement with external objects or being pulled, thereby further ensuring the data connection and transmission between the thermal printer body 103 and the terminal device cash register 102.

[0024] See also Figure 2The driving assembly shown in the figure includes a rotating tube 301 rotatably connected to the side of the mounting plate 201 away from the support platform 101, the rotating tube 301 is connected to the mounting tube 302 through a telescopic assembly, the mounting tube 302 is slidably connected to the first T-shaped rod 303, the first T-shaped rod 303 is fixedly connected to the side close to the mounting plate 201 with a storage rod 304, and the mounting plate 201 is provided with a limiting assembly for limiting the rotating tube 301;

[0025] It should be noted here that: by setting the driving component, it is convenient to drive the data cable to rotate and be stored in the storage slot 202.

[0026] See also Figure 4 The telescopic assembly shown in the figure includes a second T-shaped rod 401 slidably connected to the rotating tube 301, an end of the mounting tube 302 away from the storage rod 304 is connected to the second T-shaped rod 401, an end of the second T-shaped rod 401 located inside the rotating tube 301 is fixedly connected to a telescopic plate 402, a first spring 403 is sleeved on the side wall of the second T-shaped rod 401, and both ends of the first spring 403 are respectively connected to the telescopic plate 402 and the inner wall of the rotating tube 301;

[0027] It should be noted here that: by providing the telescopic assembly, it is convenient to pull the storage rod 304 out of the storage slot 202 , thereby facilitating the insertion of the data cable into the storage slot 202 .

[0028] Working principle: When the thermal printer body 103 placed on the support platform 101 is connected to the terminal device cash register 102, one end of the USB data cable is inserted into the USB interface 104 of the cash register 102, and the other end is inserted into the USB interface 104 on the thermal printer body 103, so as to realize the data connection between the two, which is convenient for data transmission and printing;

[0029] After the USB data cable connects the thermal printer body 103 with the terminal device cash register 102, when storing the redundant USB data cable, first pull the second T-bar 401 upwards to drive the storage rod 304 on one side of the first T-bar 303 to move away from the mounting plate 201, and then insert the middle part of the USB data cable from the through hole 203 into the storage slot 202. At this time, release the lifting of the second T-bar 401, and under the elastic action of the first spring 403, the storage rod 304 is inserted into the storage slot 202 and blocks the USB data cable.

[0030] After the storage rod 304 is inserted into the storage slot 202, the rotating tube 301 is rotated to drive the storage rod 304 to rotate. During the rotation of the storage rod 304, under the pulling force and the sliding action of the storage rod 304 on the mounting tube 302, the USB data cable is stored in the spiral storage slot 202, thereby realizing the storage operation of excess USB data cables, avoiding the long data cables from falling off or being damaged due to entanglement or pulling with external objects, thereby further ensuring the data connection and transmission between the thermal printer body 103 and the terminal device cash register 102.

[0031] Example 2

[0032] See also Figure 4 This embodiment further explains Example 1. The limiting assembly shown in the figure includes a fixing plate 501 fixedly connected to the mounting plate 201. The fixing plate 501 is connected to a limiting plate 502 on one side close to the rotating tube 301 through a guide assembly. A plurality of limiting holes 503 are formed in an annular manner on the side wall of the rotating tube 301. Each limiting hole 503 is matched with the limiting plate 502. The two opposite side walls of the limiting plate 502 are formed with inclined surfaces 504.

[0033] It should be noted here that: through the setting of the limiting component, during the rotation of the rotating tube 301, each limiting hole 503 will be driven to rotate. When the limiting hole 503 and the limiting plate 502 are against each other, the interaction force of the inclined surface 504 and the guiding action of the guide component will push the limiting plate 502 to move away from the rotating tube 301. After the excess USB data cable is stored, the limiting plate 502 will be pushed into the limiting hole 503 under the elastic action of the guide component, and will be against the bottom wall of the limiting hole 503. Therefore, under the tight action of the limiting plate 502, the rotating tube 301 is limited, and the stability of the USB data cable storage is further guaranteed.
