[0033] Specifically, in the above embodiment, the second fixing mechanism 2 includes a second fixing block 201, and the lower end face of the second fixing block 201 is fixedly connected to a connecting block 202, the connecting block 202 passes through the upper end face of the first fixing block 101, and is rotatably arranged inside a sliding groove 103 opened in the middle position of the upper end face of the first fixing block 101, and a hand-pull block 203 is slidably arranged on both side end faces of the second fixing block 20, and a third reset spring 204 is fixedly arranged between the upper sides of the end faces on the opposite sides of the two hand-pull blocks 203.

[0034] Specifically, in the above embodiment, a second circular groove 105 is opened at the four corners of the inner bottom surface of the sliding groove 103, a first cylinder 106 is fixedly provided at the four corners of the lower end surface of the mouth-shaped plate 104, and the four first cylinders 106 are plugged into and matched with the four second circular grooves 105 one by one.

[0035] Specifically, in the above embodiment, a first return spring 107 is fixedly disposed between the lower end surfaces of the four first cylinders 106 and the inner bottom surfaces of the four second circular grooves 105 .

[0036] Specifically, in the above embodiment, four second cylinders 108 are fixedly connected to the lower end surface of the mouth-shaped plate 104, and the four second cylinders 108 all penetrate the inner bottom surface of the sliding groove 103 and extend into the four first circular grooves 102, and are plug-fitted with the four fixing rings 4 one by one.

[0038] Specifically, in the above embodiment, a rotating block 206 is rotatably provided on the upper sides of the front and rear end surfaces of the second fixed block 201 , and the two rotating blocks 206 are slidably matched with the front and rear end surfaces of the audio distributor 205 .

[0039] Specifically, in the above embodiment, a through hole 114 is provided in the middle of the first fixing block 101 and passes through the upper and lower surfaces thereof. The through hole 114 is used to pass a support column to facilitate fixing the entire device to the support column.

[0040] Specifically, in the above embodiment, a plurality of pointed blocks 113 are fixedly disposed on the lower end surface of the slip ring 110 .

[0041] When removing a single damaged speaker body 3 from a high place, by pulling the mouth-shaped plate 104 upward, the four first cylinders 106 on the lower end surface of the mouth-shaped plate 104 pull the first reset spring 107 to deform it, and at this time the mouth-shaped plate 104 drives the four second cylinders 108 on the surface to move upward together, so that the lower ends of the four second cylinders 108 leave the inner walls of the four fixing rings 4, and the damaged speaker body 3 can be removed at this time. After removal, release the pull on the mouth-shaped plate 104, and the first cylinder 106 is driven downward by the rebound force of the first reset spring 107, thereby driving the mouth-shaped plate 104 and the four second cylinders 108 to move downward together, and at this time the remaining three second cylinders 108 re-enter the inner wall of the fixing ring 4.

[0042] When the mouth-shaped plate 104 is pulled, the four second cylinders 108 will leave the inner walls of the four fixing rings 4, releasing the clamping of the four first circular grooves 102 on the four fixing rings 4, and the first circular grooves 102 will abut against the inner walls of the fixing rings 4, so that the speaker body 3 can only slide toward the opening of the first circular grooves 102.

[0043] When installing the second fixed block 201, the two hand-pull blocks 203 are pulled to both sides while the through hole 114 opened in the middle of the first fixed block 101 is manually passed through the support column (not shown in the figure). When the second fixed block 201 can no longer move downward, the pulling of the two hand-pull blocks 203 is released. At this time, under the action of the third reset spring 204, the protrusions on the surfaces of the two hand-pull blocks 203 will pass through the holes opened on the second fixed block 201 and enter the inner wall of the support column. Here, the support column is a rod inserted into the soil. A circular hole is opened on the upper side of the outer end surface of the rod, so that the protrusions on the surface of the hand-pull block 203 can enter the circular hole of the support column. When multiple speaker bodies 3 are damaged, the interface of the wire can be removed from the audio distributor 205 first. At this time, the two hand-pull blocks 203 can be pulled to both sides while the second fixed block 201 is taken upward to remove the first fixing mechanism 1 from the support column.

[0044] After fixing the second fixing block 201, when the orientation of the four speaker bodies 3 needs to be adjusted, first unplug the wires connecting the audio distributor 205 and the four speaker bodies 3, and then squeeze the top plate 112 upward while holding the first fixing block 101 to rotate it. When squeezing the top plate 112, the top plate 112 drives the slip ring 110 to move upward, so that the pointed block 113 on the lower end surface of the slip ring 110 does not abut against the inner bottom surface of the connecting block 202. At this time, the first fixing block 101 can be rotated. After rotating to a suitable position, release the squeezing of the top plate 112. Under the action of the rebound force of the second reset spring 111, the slip ring 110 moves downward, so that the pointed block 113 on its surface abuts against the connecting block 202 again, thereby fixing the first fixing block 101.

[0045] The working principle of the speaker fixing device which is easy to adjust provided by the utility model is as follows:

[0046] When checking whether the speaker body 3 is damaged, place the ladder against one end of the support column, and then climb to the position of the first fixed block 101. At this time, unplug the audio wire interfaces connected to the four speaker bodies 3, first check the speaker body 3 on the front, and then press the top plate 112 upwards while holding the first fixed block 101 to rotate, turn another speaker body 3 to the front, and then continue the same operation as the upper end, and check the remaining speakers in turn. When multiple speaker bodies 3 are found to be damaged, disconnect all audio wire interfaces from the audio distributor 205, and then pull the two hand-pull blocks 203 to both sides while holding the second fixed block 201 and moving it upward to remove the entire first fixing mechanism 1. After removing the first fixing mechanism 1, pull the mouth-shaped plate 104 upwards while pulling out the damaged speaker body 3, and at this time, the two rotating blocks 206 can also be rotated so that the rotating blocks 206 do not collide with the audio distributor 205, and then take out the audio distributor 205 and check the audio distributor 205.

[0047] Finally, it should be noted that the above description is only an embodiment of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made using the contents of the present utility model specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present utility model.
