A second rope 10 is located at one end of the second connecting buckle 8 furthest from the second connecting buckle 7. An internal threaded cylinder 13 is fixedly connected to the end of the noise collector 1. A textured elastic cloth 14 is fixedly connected to the left side of the rear end of the noise collector 1. An elastic pull strap 15 is provided on the right side of the rear end of the noise collector 1. A hook-faced elastic cloth 16 is fixedly connected to the front end of the elastic pull strap 15. The first connecting buckle 7 and the second connecting buckle 8 are fixedly connected to the noise collector 1. The threads on the outside of the external threaded cylinder 12 match the threads inside the internal threaded cylinder 13. The shape and size of the outside of the external threaded cylinder 12 are consistent with the shape and size of the inside of the internal threaded cylinder 13. The external threaded cylinder 12 can move left and right along the inside of the internal threaded cylinder 13. The hook-faced elastic cloth 16 is elastic. The textured elastic cloth 14 and the hook-faced elastic cloth 16 are bonded to each other. Two methods are available for easy carrying.

[0027] Specifically, such as Figure 1 , Figure 2 and Figure 3As shown, when using the device, if you need to move other measuring objects that require your hands, you can pull out the first rope 9 from the first rope storage box 5 and the second rope 10 from the second rope storage box 6. Then, screw the external threaded cylinder 12 into the internal threaded cylinder 13 to combine the first rope 9 and the second rope 10. You can choose to hang it around your neck for easy carrying. If you need to climb to the measuring position, you can tear the hook-faced elastic fabric 16 off the napped elastic fabric 14, place the noise collector 1 on your arm, and then pass the elastic strap 15 through your arm and stick it to the napped elastic fabric 14 to tie the noise collector 1 to your arm. Multiple methods are available for easy carrying.

[0028] Example 2: The rear end of the noise collector 1 is provided with a battery compartment cover 17, the front end of the battery compartment cover 17 is provided with a first battery compartment 18, the first battery compartment 18 is provided with three sets of lithium batteries 19, the top of the first battery compartment 18 is fixedly connected to a second battery compartment 20, the inside of the second battery compartment 20 is fixedly connected to a nickel-metal hydride battery 21, an alarm light 22 is provided above the display screen 2, the lithium batteries 19 and nickel-metal hydride batteries 21 are electrically connected, the lithium batteries 19 and nickel-metal hydride batteries 21 are electrically connected to the alarm light 22, the power is not interrupted when the batteries are replaced, and the battery can run for a long time;

[0029] Specifically, such as Figure 1 and Figure 4 As shown, during use, the lithium battery 19 transfers power to the nickel-metal hydride battery 21, which in turn powers the noise collector 1. If the battery is low when the device is powered on, a low battery warning will be displayed on the screen 2. If the battery is low after a long period of standby, the alarm light 22 will flash to indicate that the lithium battery 19 can be replaced in time. Since the nickel-metal hydride battery 21 is powered, the device will not shut down when the battery is removed, and the battery can be replaced without disconnecting the power.

[0030] Example 3: A protective shell 23 is provided on the periphery of the noise collector 1. Air cushion corners 24 are fixedly connected to the four corners of the protective shell 23. Sponge filling material 25 is fixedly connected inside the protective shell 23. Rubber filling material 26 is fixedly connected inside the air cushion corners 24. The shape and size of the inside of the protective shell 23 are consistent with the shape and size of the outside of the noise collector 1. The sponge filling material 25 and the rubber filling material 26 are tightly attached to each other to prevent the product from falling and breaking.

[0031] Specifically, such as Figure 1 and Figure 5 As shown, when in use, electronic products are easily damaged when dropped, so air cushion corners 24 are provided. The rubber filler 26 inside the air cushion corners 24 can protect the most vulnerable four corners and prevent the four corners of the machine from cracking after being dropped. At the same time, the sponge filler 25 inside the protective shell 23 is elastic and can cushion the impact when dropped. Multiple protections prevent product damage.

[0032] Working Principle: When using this invention, if it requires moving other measuring objects and occupies both hands, the first rope 9 can be pulled out from the first rope storage box 5, and the second rope 10 from the second rope storage box 6. Then, the external threaded cylinder 12 is screwed into the internal threaded cylinder 13 to combine the first rope 9 and the second rope 10. It can be worn around the neck for easy carrying. If it requires climbing to the measuring position, the hook-faced elastic fabric 16 can be torn from the napped elastic fabric 14, the noise collector 1 placed on the arm, and the elastic strap 15 passed through the arm and adhered to the napped elastic fabric 14 to secure the noise collector 1 to the arm. The lithium battery 19 transfers power to the nickel-metal hydride battery 21, which in turn powers the noise collector 1. If the battery is low while the device is powered on, a low battery warning will be displayed on the screen 2. If the battery is low after a long period of standby, the alarm light 22 will flash, indicating that the lithium battery 19 can be replaced in time. Since the nickel-metal hydride battery 21 is powered, there is no need to remove the battery to turn off the device. During use, because electronic products are easily damaged when dropped, air cushion corners 24 are provided. The rubber padding 26 inside the air cushion corners 24 can protect the most vulnerable four corners and prevent the corners of the machine from cracking after a drop. At the same time, the sponge padding 25 inside the protective shell 23 is elastic and can cushion the impact when dropped.
