[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] See also Figures 1 to 5 A portable microphone comprises a receiving end 1, a mounting chamber 2 and a receiving sleeve 3, wherein the mounting chamber 2 can slide inside the receiving sleeve 3, so that when not in use, the mounting chamber 2 can be placed inside the receiving sleeve 3, thereby effectively reducing the overall volume of the device and making it convenient to carry;

[0028] A mounting block 5 is fixedly mounted on the mounting bin 2, and fixing cylinders 6 are fixedly mounted on both sides of the mounting block 5.

[0029] By rotating the mounting block 5, the mounting chamber 2 and the receiving end 1 thereon can be rotated, thereby changing the angle of the receiving end 1, making the microphone more adaptable.

[0030] A connecting rod 8 is slidably mounted inside the fixed cylinder 6, and an ejection block 7 is fixedly mounted on the other end of the connecting rod 8;

[0031] By applying pressure to the ejection block 7 , the connecting rod 8 can be moved inside the fixing cylinder 6 .

[0032] The inner wall of the accommodating sleeve 3 is provided with two slide grooves 10 for the ejection block 7 to slide, and the accommodating sleeve 3 is provided with exposure grooves 9 at both ends of the slide grooves 10, and the exposure grooves 9 are through grooves.

[0033] By pressing the ejection block 7, the ejection block 7 is made horizontal with the slide groove 10. At this time, the ejection block 7 can move on the slide groove 10. When the ejection block 7 moves to the edge of the slide groove 10, the ejection block 7 will be exposed from the exposure groove 9 because there is no obstruction, thereby maintaining a stable connection relationship between the installation bin 2 and the accommodating sleeve 3.

[0034] The two exposure grooves 9 correspond to two scenarios: the installation chamber 2 is completely inside the accommodating sleeve 3 and the installation chamber 2 is completely extended out of the accommodating sleeve 3 .

[0035] A fixing ring 11 is fixedly mounted on the fixing cylinder 6, and an inner gear ring 12 is fixedly mounted inside the fixing ring 11;

[0036] Two fixed rods 17 are rotatably installed inside the mounting block 5, and a moving rod 15 is slidably installed inside the fixed rod 17. A gear 14 is fixedly installed on the other end of the moving rod 15, and the gear 14 is fixedly connected to the connecting rod 8;

[0037] When the gear 14 is inside the inner gear ring 12, since the ejector block 7 is inside the exposed groove 9, the ejector block 7 and the connecting rod 8 cannot rotate, and the gear 14 cannot rotate, which makes the inner gear ring 12 unable to rotate, and the fixing cylinder 6 cannot rotate, so that the mounting bin 2 and the receiving end 1 remain at a stable angle.

[0038] A spring 16 is fixedly mounted on the fixing rod 17 , and the other end of the spring 16 is fixedly mounted on the gear 14 .

[0039] The internal gear ring 12 is matched with the gear 14 .

[0040] An accommodating cavity 13 is defined at one end of the fixing ring 11 facing the gear 14 .

[0041] When the angle adjustment is required, the ejection block 7 is pressed to move the connecting rod 8 inside the fixed tube 6, and then the connecting rod 8 drives the gear 14 to move, and the gear 14 moves to the inside of the accommodating cavity 13, and the gear 14 can be separated from the inner gear ring 12. At this time, the inner gear ring 12 is not restricted, and then the fixed tube 6 can be rotated, and the installation bin 2 and the receiving end 1 can be adjusted in angle.

[0042] When no external force is applied, the spring 16 allows the gear 14 to return to the inner gear ring 12, thereby fixing the cylinder 6 so that it cannot rotate, thereby maintaining the stability of the angles of the installation bin 2 and the receiving end 1.

[0043] The cross section of the ejection block 7 is a rectangular structure, and the exposed groove 9 is adapted to the ejection block 7. When the ejection block 7 is on the exposed groove 9, the connecting rod 8 and the gear 14 cannot rotate.

[0044] A standing plate 4 is fixedly mounted on the bottom of the accommodating sleeve 3 , and a counterweight may be provided inside the accommodating sleeve 3 .

[0045] The purpose of setting the standing board 4 and the counterweight is to place the entire device on a flat surface, thereby eliminating the need for manual picking up and making it more convenient.

[0046] The working process of the utility model is as follows: when it is needed to be used, the ejection block 7 is pressed so that the ejection block 7 is level with the slide groove 10, so that the ejection block 7 can move on the slide groove 10. When the ejection block 7 moves to the edge of the slide groove 10, since there is no obstruction, the ejection block 7 will be exposed from the exposure groove 9, thereby keeping the installation bin 2 and the accommodating sleeve 3 as a whole in the longest state. At this time, it can be taken manually.

[0047] When the entire device needs to be placed on the desktop, the angle is adjusted first, and the ejection block 7 is pressed. However, the ejection block 7 will not be exposed from the groove 9 and will not be disengaged. At this time, the connecting rod 8 moves inside the fixed cylinder 6, and then the connecting rod 8 drives the gear 14 to move. The gear 14 moves into the accommodating cavity 13, and the gear 14 can be separated from the inner gear ring 12. At this time, the inner gear ring 12 is not restricted, and then the fixed cylinder 6 can be rotated, and the installation chamber 2 and the receiving end 1 can be adjusted in angle.

[0048] Afterwards, the force applied to the ejection block 7 is removed, and the presence of the spring 16 causes the gear 14 to return to the inside of the inner gear ring 12, thereby fixing the cylinder 6 so that it cannot rotate, thereby maintaining the stability of the angle of the installation compartment 2 and the receiving end 1. Afterwards, the entire device is placed on a plane through the standing board 4 and the counterweight, so that the microphone can be used normally.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
