When it is temporarily fixed, open the connecting doors connected by the buckles on both sides, stretch the connecting rod, and make the connecting rod and the inclined suction cup extend out of the call device body. When the connecting rod is stretched to the longest, the support blocks on the connecting rod enter the circular groove in the swing rod, and the suction cup is rotated so that the suction cup faces the desktop or wall. At this time, the support blocks are no longer aligned with the support grooves in the swing rod to prevent the connecting rod from moving back. The suction cup can fix the call device body. When it needs to be fixed for a long time, the through holes and screw holes on the connecting plate can make the call device body fixed or hung on the desktop or wall. Compared with the prior art, there is an improvement that the call device body can be fixed at any time.

[0012] 2. During use, when the heat dissipation efficiency of relying on the heat dissipation holes and heat dissipation grooves on the calling device body and the outer fixed block is not enough, open the two fixed shafts connected by the buckle, swing the movable rod along the swing groove, the movable rod drives the annular rack to slide in the annular groove, the annular rack drives the meshing pinion to rotate, the rotation of the pinion drives the meshing spur rack to slide in the square groove, the movement of the spur rack drives the fixed block to move, thereby opening the calling device body on three sides, making the heat dissipation faster, and compared with the prior art, there is an improvement in the heat dissipation effect.

[0030] The connecting rod 9 is sleeved into the swing rod 8, and the connecting rod 9 is fixedly connected with a support block 27 above one end in the swing rod 8. The support block 27 is provided with a plurality of support grooves 28 distributed in a circular array, and the swing rod 8 is provided with the same number of support grooves 28 as the support block 27. Each support groove 28 is connected to a circular groove 29 at the outermost end. One end of the connecting door 3 is hinged and the other end is snap-connected to the outer shell 1. The cooperation of the support groove 28 and the support block 27 allows the connecting rod 9 to move in the swing rod 8. The cooperation of the support groove 28 and the circular groove 29 allows the connecting rod 9 to be stretched to the longest end and rotated by an angle, so that the connecting rod 9 can be limited to move to the support groove 28 in the swing rod 8, thereby preventing the suction cup 10 from moving back after rotation.

[0031] The tooth width of the pinion gear 18 is greater than the sum of the spur rack 19 and the annular rack 16. The pinion gear 18 engages with the annular rack 16 while engaging with the spur rack 19. Three spur racks 19 are provided on the upper left and right sides, and three pinion gears 18 are also provided. The fixing block 20 is connected to the outer shell of the calling device body 30.

The cooperation of the square block 32 and the square groove 33 enables the spur rack 19 to slide back and forth in the square groove 33 in the connecting cavity 4, and a pair of fixed shafts 34 are limited to move to the movable rods 17 at both ends of the swing groove 31, thereby preventing the movable rod 17 from moving when not in operation.

[0033] The specific implementation method is:

[0034] When in use, when it needs to be fixed, the connecting shaft 5 is pressed, and the connecting shaft 5 drives the clockwise sawtooth 21 fixedly connected above to move forward along the connecting block 23 under the limit of the first connecting groove 22. When the clockwise sawtooth 21 moves to the counterclockwise sawtooth 24 on the cam 6, it contacts the counterclockwise sawtooth 24, thereby driving the counterclockwise sawtooth 24 and the cam 6 to move backward, thereby driving the connecting rod 7 to move backward, and then compressing the reset spring 11. When the counterclockwise sawtooth 24 moves to the tail end of the connecting block 23, the limit of the connecting block 12 is lost, and the angle of the sawtooth at the tail end of the connecting block 23 is consistent with that of the counterclockwise sawtooth 14. Under the action of the reset spring 11, the counterclockwise sawtooth 24 and The cam 6 rotates a certain angle along the connecting block 23, so that the connecting block 23 is connected to the counterclockwise serrations 24 on the cam 6, and then the connecting block 23 fixes the cam 6. The connecting rod 7 drives the swing rod 8 to move backward during the backward movement. Under the limitation of the limit shaft 26 and the inner wall of the outer shell 1, the connecting rod 7 drives the swing rod 8 to swing gradually vertically to connect the door 3. At the same time, the connecting rod drives the connecting plate 12 to extend out of the calling device body 30. When a short-term fixation is required, the connecting door 3 connected by the buckles on both sides is opened, and the connecting rod 9 is stretched. The supporting block 27 on the connecting rod 9 moves in the supporting groove 28 in the swing rod 8, so that the connecting rod 9 and the inclined suction cup 10 extend out of the calling device body 30, and the stretching When the connecting rod 9 is at its longest, the support blocks 27 on the connecting rod 9 all enter the circular grooves 29 in the swing rod 8, and the suction cup 10 and the connecting rod 9 are rotated so that the suction cup 10 faces the desktop or the wall. At this time, the support blocks 27 are no longer aligned with the support grooves 28 in the swing rod 8, so as to prevent the connecting rod 9 from moving back. The suction cup 10 can fix the call device body. When it is necessary to fix it for a long time, the through holes 13 and the screw holes 14 on the connecting plate 12 can make the call device body 30 fixed or hung on the desktop or the wall. When the fixation is completed, the suction cup 10 and the connecting rod 9 are reset to the call device body 30, and the connecting shaft 5 is pressed. The clockwise sawtooth 21 drives the counterclockwise sawtooth 24 to move, so that the connecting shaft 5 is pressed. The connecting block 23 enters the counterclockwise serrations 24 again, the reset spring 11 resets, and the connecting plate 12 resets. When the heat dissipation efficiency relying on the heat dissipation holes and heat dissipation grooves on the calling device body 30 and the outer fixed block 20 is not enough, the two fixed shafts 34 connected by the buckle are opened, and the movable rod 17 is swung along the swing groove 31. The movable rod 17 drives the annular rack 16 to slide in the annular groove 15, and the annular rack 17 drives the meshing pinion 18 to rotate. The rotation of the pinion 18 drives the meshing spur rack 19 to slide in the square groove 33. The movement of the spur rack 19 drives the fixedly connected fixed block 20 to move, thereby opening the calling device body 30 on three sides to make heat dissipation faster.

[0035] Working principle of the present invention: refer to Figure 1-12, open the connecting door 3, by pressing the connecting shaft 5, the connecting shaft 5 drives the swing rod 8 to vertically connect the door 3, and at the same time, the connecting plate 12 extends out of the calling device body 30, and the connecting rod 9 is stretched to the outside of the calling device body 30. The suction cup 10 on the connecting rod 9 can fix the calling device body 30 on the desktop or wall. The through hole 13 and the screw hole 145 on the connecting plate 12 can make the calling device body 30 fixed or hung on the desktop or wall, and stretch the movable rod 17. The movable rod 17 drives the spur rack 19 to move and open the fixed block 20 on the calling device body 30 to help dissipate heat.
