[0002] A walkie-talkie is a two-way mobile communication tool. Without the need for any network support, it can make calls without generating call charges. It is suitable for relatively fixed and frequently communicating occasions and consists of a housing, a main unit, a battery, a belt clip, a desktop charger, and an antenna. This kind of walkie-talkie with a single function and a large volume is inconvenient to carry. Most users hold it in their hands. In the prior art, Chinese Utility Model Patent No. CN210405289U discloses a portable multi-functional walkie-talkie, which includes a walkie-talkie body and a storage tube. Inside one side of the walkie-talkie body, a storage tube is vertically arranged, and an antenna is slidably connected inside the storage tube, and the upper part of the antenna extends out of the upper surface of the walkie-talkie body. A guide rod is arranged at the middle position inside the storage tube. In the present invention, the body structure of the walkie-talkie is designed with a simple and generous appearance. A protective cover is clamped on one side surface of the walkie-talkie body, and a back clip is connected to one side surface of the protective cover. The protective cover adopts a four-corner wrapping design for the walkie-talkie body, improving the anti-drop ability of the walkie-talkie and preventing damage to the corners of the walkie-talkie. While protecting the corners of the walkie-talkie, it firmly clamps the walkie-talkie, making it not easy to fall off. Combined with the use of the back clip, the walkie-talkie can be hung on the waist, trouser pocket and other convenient areas for taking, facilitating the operator to perform walkie-talkie operations while manually working, being convenient to use and preventing loss. In the above technology, combined with the use of the back clip, the walkie-talkie can be hung on the waist, trouser pocket and other convenient areas for taking, facilitating the operator to perform walkie-talkie operations while manually working, being convenient to use and preventing loss. However, in some special environments, such as narrow working spaces, poor ventilation and the existence of complex obstacles, the walkie-talkie fixed by the back clip is easily hooked or scratched, which may cause equipment damage.

The pull rod 30 drives the second clamping block 38 on the outermost third connecting plate 19 through the second pull rope 33. When the second clamping block 38 on the outermost third connecting plate 19 moves out of the inner part of the third clamping groove 37 on the adjacent third connecting plate 19, the outermost third connecting plate 19 can rotate. At the same time, the elastically - arranged third clamping block 45 is released from the limit. When the outermost third connecting plate 19 rotates, the third clamping block 45 on the outermost third connecting plate 19 is inserted into the inner part of the third receiving groove 36 on the adjacent third connecting plate 19, completing the angle adjustment of the outermost third connecting plate 19 relative to the adjacent third connecting plate 19. At the same time, when the third clamping block 45 on the outermost third connecting plate 19 is inserted into the inner part of the third receiving groove 36 on the adjacent third connecting plate 19, it drives the third receiving groove 36 on the adjacent third connecting plate 19 to move out of the inner part of the third clamping groove 37 on another group of adjacent third connecting plates 19 through the third pull rope 53. Repeating the above steps can complete the bending adjustment of multiple groups of third connecting plates 19.

[0025] The specific solution of this scheme is as follows: Place the walkie - talkie body 2 inside the walkie - talkie housing 1. When it is necessary to place the walkie - talkie housing 1 at the waist or arm of the operator, pull the pull rod 30. With the cooperation of the first pull rope 29, the pull rod 30 can drive the first clamping block 25 to move out of the fixed slot 21. When moving out, the elastically - arranged push plate 7 is no longer limited by the fixing plate 4. Under the action of the first return spring 6, the push plate 7 is pushed out. When being pushed out, the first airbag 10 is compressed, and the air inside the first airbag 10 is discharged into the second airbag 15 through the first exhaust pipe 11. The second airbag 15 expands and pushes out the limit block 12 to limit the walkie - talkie body 2, preventing the walkie - talkie body 2 from falling out of the walkie - talkie housing 1 when the walkie - talkie housing 1 drops. When releasing the limit on the guide rod 20, the fixing plate 4 is lifted under the action of the first return spring 6. At this time, the guide rod 20 moves upward along the guide groove 16. When the elastically - arranged trigger rod 51 coincides with the elastically - arranged first abutting block 23, the elastically - arranged trigger rod 51 abuts the first abutting block 23 to one side. When the first abutting block 23 moves, with the cooperation of the second pull rope 33, the second clamping block 38 on the first connecting plate 17 is pulled out from the inner part of the third clamping groove 37 on the second connecting plate 18. At this time, the first connecting plate 17 and the second connecting plate 18 can be released from the limit and rotate. When the second clamping block 38 on the first connecting plate 17 no longer abuts against the second abutting block 41, the fourth airbag 42 is no longer compressed. At this time, the third clamping block 45 is no longer limited by the third airbag 48. The second connecting plate 18 that rotates 90° relative to the first connecting plate 17. At this time, the elastically arranged third clamping block 45 coincides with the third receiving groove 36 and is inserted into the third receiving groove 36, completing the 90° rotation of the second connecting plate 18. At this time, the fixing plate 4 is in a "7" - shaped structure, which is convenient for the operator to clamp the walkie - talkie housing 1 at the waist; When it is necessary to be clamped to the operator's arm, pull the pull rod 30 on the outermost third connecting plate 19. The pull rod 30 pulls the second clamping block 38 on the outermost third connecting plate 19 through the second pull rope 33. When the second clamping block 38 on the outermost third connecting plate 19 moves out of the third clamping groove 37 on the adjacent third connecting plate 19, the outermost third connecting plate 19 can rotate. At the same time, the elastically arranged third clamping block 45 is released from the limit. When the outermost third connecting plate 19 rotates, the third clamping block 45 on the outermost third connecting plate 19 is inserted into the third receiving groove 36 on the adjacent third connecting plate 19, completing the angle adjustment of the outermost third connecting plate 19 relative to the adjacent third connecting plate 19. At the same time, when the third clamping block 45 on the outermost third connecting plate 19 is inserted into the third receiving groove 36 on the adjacent third connecting plate 19, it will drive the third receiving groove 36 on the adjacent third connecting plate 19 to move out of the third clamping groove 37 on another group of adjacent third connecting plates 19 through the third pull rope 53. Repeating the above steps can complete the bending adjustment of multiple groups of third connecting plates 19. After the bending adjustment is completed, the walkie - talkie housing 1 can be fixed to the operator's arm through the fixing plate 4.
