[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments. Example

[0026] like Figures 1-8As shown, a convenient screw-rotating structure for a USB to RS232 serial cable connector includes: an RS232 connector body 1, with a cable 11 connected to the bottom end of the RS232 connector body 1; a front housing 12 and a rear housing 13 on the outside of the RS232 connector body 1; and a male connector 14 on the top of the RS232 connector body 1; a connecting mechanism located between the front housing 12 and the rear housing 13 for easy connection and fixation with the RS232 connector of the device; and a fixing mechanism located on the inner wall of the front housing 12 for fixing the toggle cylinder 22.

[0027] One end of cable 11 is connected to a USB connector. When in use, one end of the USB connector is plugged into the USB port, and then one end of the male connector 14 of the serial cable RS232 connector body 1 is plugged into the female connector of the device's RS232 connector. The connection mechanism is used to fix the cable to the device's RS232 connector, preventing the male connector 14 from coming off the female connector. This makes the connection simpler and more convenient. Secondly, the fixing mechanism fixes the toggle cylinder 22 to prevent accidental activation that could cause the toggle cylinder 22 to rotate and affect the connection stability of the serial cable RS232 connector body 1. Example

[0028] Based on Embodiment 1, the connecting mechanism includes: an opening 2, a retainer 21, a toggle cylinder 22, a mounting hole 23, a connecting rod 24, and a screw 25. Openings 2 are provided on both sides of the front housing 12 and the rear housing 13. A retainer 21 is fixedly connected to each opening 2. A toggle cylinder 22 is rotatably connected between the top and bottom of the retainer 21. A hexagonal mounting hole 23 is provided on the toggle cylinder 22. A connecting rod 24 is slidably connected inside the mounting hole 23. A screw 25 is fixedly connected to the top of the connecting rod 24. A top plate 26 is fixedly installed on the outside of the male end 14. Two through holes 27 are provided on the top plate 26. The tops of the two screws 25 pass through the through holes 27 and extend to the outside. Fitting frames 28 are fixedly connected to the inner walls of the opposite side of the front housing 12 and the rear housing 13 near the top. The top plate 26 is located between the two fitting frames 28.

[0029] When the male end 14 of the RS232 serial cable connector body 1 is inserted into the female end of the device's RS232 connector, the male end 14 is inserted into the female end, and one end of the two screws 25 is opposite to the threaded sleeve on the female end. Manually rotating the actuating cylinder 22 between the retainers 21 causes the connecting rod 24 to rotate, causing one end of the screw 25 to screw into the threaded sleeve on the female end. The hexagonal mounting hole 23 and the connecting rod 24 allow the connecting rod 24 to rotate and also allow it to remain within the mounting hole 23. The sliding mechanism allows the connecting rod 24 to move a distance from the mounting hole 23 when the screw 25 is screwed into the sleeve. When the connecting rod 24 contacts the fitting frame 28, the male head completes the connection and fixation with the female head. Reversely turning the actuating cylinder 22 can drive the screw 25 to rotate in the opposite direction, so that the screw 25 is unscrewed from the sleeve of the female head and released from fixation. The actuating cylinder 22 can be operated with a single finger, which is simpler and less restricted by surrounding objects and narrow spaces. Moreover, the actuating cylinder 22 can be operated with a single finger, which is faster.

[0030] The rear housing 13 has buckles 29 fixedly connected to the inner walls on opposite sides, the front housing 12 has slots 210 respectively on the inner walls on opposite sides, the inner wall of the front housing 12 near the bottom has two positioning rods 211 fixedly connected to the inner wall on opposite sides, and the inner wall of the rear housing 13 near the bottom has two positioning cylinders 212 fixedly connected to the inner wall on opposite sides.

[0031] The front housing 12 and the rear housing 13 are connected and fixed by a buckle 29 and a slot 210, and the front housing 12 and the rear housing 13 can be disassembled. The positioning rod 211 and the positioning cylinder 212 position the front housing 12 and the rear housing 13 so that the front housing 12 and the rear housing 13 are precisely assembled together. The serial cable RS232 connector body 1 is fixed by the top plate 26, the fitting frame 28 and the support plate on the inner wall of the rear housing 13 to prevent the serial cable RS232 connector body 1 from becoming loose. Example

[0032] Based on Embodiment 1, the fixing mechanism includes: a connecting frame 3, a movable plate 31, a fixing block 32, a fitting block 33, and a spring 34. Two connecting frames 3 are fixedly connected to the inner wall of the front housing 12 in a staggered manner. Movable plates 31 are slidably connected inside each connecting frame 3. Fixing blocks 32 are fixedly connected to the opposite ends of the two movable plates 31. Fitting blocks 33 are fixedly connected to the opposite ends of the two movable plates 31. Springs 34 are connected between the fitting blocks 33 and the opposite ends of the connecting frames 3. An installation groove 35 is provided on the front housing 12. A pressure plate 36 is slidably connected inside the installation groove 35. A push block 37 that cooperates with the fitting block 33 is fixedly connected to one end of the pressure plate 36. The actuating cylinder 22 is arranged in a plum blossom shape. A groove that fits the plum blossom shape on the outside of the actuating cylinder 22 is provided at one end of the fixing block 32.

[0033] When the actuating cylinder 22 is turned, press the pressure plate 36 with one finger. The pressure plate 36 slides in the mounting groove 35, pushing the push block 37 to move. The inclined surface of the push block 37 engages with the inclined surface of the mating block 33, pushing the two mating blocks 33 to drive the two moving plates 31 to move in opposite directions. The mating blocks 33 compress the spring 34 to compress and store energy, driving the two fixed blocks 32 to move relative to each other and separate from the actuating cylinder 22, thereby releasing the fixation of the actuating cylinder 22. At this time, turn the actuating cylinder 22 with another finger. After the actuating cylinder 22 is turned, release the pressure plate 36. The spring 34 releases its elasticity and pushes the two mating blocks 33 to move relative to each other. The mating blocks 33 move and engage with the push block 37, pushing the push block 37 and the pressure plate 36 back to the initial position. The mating blocks 33 push the moving plates 31 and the fixed blocks 32 to move in opposite directions, so that the groove of the fixed block 32 fits against the edge of the actuating cylinder 22, fixing the actuating cylinder 22 and preventing the actuating cylinder 22 from rotating under external force.
