DETAILED DESCRIPTION OF THE INVENTION

(7) With reference to FIGS. 1-4, a microphone holder with an adjustable clamping spacing of an embodiment according to the present invention comprises a coupling seat 1, a holding seat 2, and an adjusting ring 3. The coupling seat 1 includes a lower end having a coupling portion 11 for coupling with a microphone stand 5. The coupling seat 1 further includes an upper end having a lower assembling portion 12

(8) The holding seat 2 is made of flexible, deformable, and shape-restorable material. The holding seat 2 includes a lower end having an upper assembling portion 21 pivotably connected to the upper assembling portion 12 of the coupling seat 1. The holding seat 2 further includes an adjusting portion 22 located above and connected to the upper assembling portion 21. The adjusting portion 22 includes substantially circular cross sections. A clamping portion 26 is located above and connected to the adjusting portion 22. The adjusting portion 22 includes a central portion having a longitudinal groove 221 extending downwards from a top end thereof. The longitudinal groove 221 is defined by a first actuating portion 23 and a second actuating portion 24 located on two sides of the longitudinal groove 221. The first actuating portion 23 of the holding seat 2 includes a top end having a first stopper portion 231 extending outwards. The second actuating portion 24 of the holding seat 2 includes a top end having a second stopper portion 241 extending outwards.

(9) The first actuating portion 23 includes a first inclined guiding face 232 located below the first stopper portion 231 and tapering downwards towards a central portion of the adjusting portion 22. The second actuating portion 24 includes a second inclined guiding face 242 located below the second stopper portion 241 and tapering downwards towards a central portion of the adjusting portion 22. The first inclined guiding face 232 includes a lower end having a first transverse groove 233 extending from an outer side towards a central portion of the adjusting portion 22. The second inclined guiding face 242 includes a lower end having a second transverse groove 243 extending from the outer side towards the central portion of the adjusting portion 22. The first transverse groove 233 includes a first wider portion 234 adjacent to the central portion of the adjusting portion 22 and having a width larger than a width of an outer end of the first transverse groove 233 adjacent to the outer side of the adjusting portion 22. The second transverse groove 243 includes a second wider portion 244 adjacent to the central portion of the adjusting portion 22 and having a width larger than a width of an outer end of the second transverse groove 243 adjacent to the outer side of the adjusting portion 22.

(10) The adjusting portion 22 includes a lower end having an outer periphery with a first threaded portion 25. The clamping portion 26 includes first and second clamping pieces 261 and 262 which have upper arcuate portions. Lower ends of the first and second clamping pieces 261 and 262 are connected to the first and second actuating portions 23 and 24, respectively. A clamping groove 263 is defined between the first and second clamping pieces 261 and 262.

(11) The adjusting ring 3 is disposed around the adjusting portion 22 of the holding seat 2. Each of the first and second stopper portions 231 and 241 has an outer edge extending beyond the longitudinal hole 31. The longitudinal hole 31 of the adjusting ring 3 includes an inner periphery having a second threaded portion 32 in threading connection with the first threaded portion 25. An upper end of the inner periphery of the longitudinal hole 31 includes an abutting portion 33 configured to abut against the first and second inclined guiding faces 232 and 242. The abutting portion 33 has a slope corresponding to a slope of each of the first and second inclined guiding faces 232 and 244. The adjusting ring 3 includes an outer periphery having a plurality of anti-slip protrusions 34.

(12) With reference to FIGS. 3 and 4, the coupling seat 1 can be coupled to the microphone stand 5 by the coupling portion 11. The second threaded portion 32 of the adjusting ring 3 is threadedly coupled to the first threaded portion 25 of the holding seat 2. When the adjusting ring 3 is in a lower position relative to the adjusting portion 22, the abutting portion 33 is aligned with bottom ends of the first and second inclined guiding faces 232 and 242. The longitudinal groove 221 has a larger width, such that the clamping groove 263 between the first and second clamping pieces 261 and 262 has a larger width.

(13) With reference to FIGS. 3 and 5, the adjusting ring 3 can be rotated to move upwardly. The abutting portion 33 can abut against the first and second inclined guiding faces 232 and 242, such that the first and second actuating portions 23 and 24 flex toward each other to gradually reduce the width of the longitudinal groove 221. Thus, the spacing between the first and second clamping pieces 261 and 262 can be reduced to reduce the width of the clamping groove 263. When desired, the adjusting ring 3 can be rotated to move downwardly, such that the width of the longitudinal groove 221 increases under the returning force of the holding seat 2. The spacing between the first and second clamping pieces 261 and 262 and the width of the clamping groove 263 are increased. The adjustment is easy. As a result, the clamping spacing of the clamping portion 26 of the microphone holder according to the present invention can be varied according to various sizes of handgrips 41 of different microphones 4, providing wider application.

(14) In adjustment, the first and second transverse grooves 233 and 243 permit easier movement of the first and second actuating portions 23 and 24. Furthermore, the first and second wider portions 234 and 244 permit easier deformation of the first and second transverse grooves 233 and 243. The adjusting convenience is further improved.

(15) In view of the above, the operation of the microphone holder according to the present invention is easy to provide wider application. The adjusting ring 3 can be moved vertically relative to the holding seat 2 by providing proper tightness therebetween or other mechanism to control the width of the clamping groove 263.

(16) Although specific embodiments have been illustrated and described, numerous modifications and variations are still possible without departing from the scope of the invention. The scope of the invention is limited by the accompanying claims.
