[0020] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0021] Reference Figure 1 As shown, a cable television network fault detection and location device includes a housing 1, a detector body 2 slidably connected inside the housing 1, a display screen 21 fixedly mounted on the upper front side of the detector body 2, several operation keys 22 below the display screen 21, a connection port 3 on the top of the detector body 2, a protective component 4 on the top of the detector body 2, fixing components 5 on both the left and right sides of the housing 1, and an elastic plate 6 fixedly connected to the rear side wall of the housing 1. When workers are working outdoors, the elastic plate 6 secures the housing 1 to the wall. The detector body 2 is fixed inside the housing 1 by the cooperation of the locking block 52 and the locking slot 23. It does not need to be held all the time. When the instrument is needed, the locking of the detector body 2 to the housing 1 can be released by pulling the pull rings 55 on both sides. The lifting block 8 will make the detector body 2 pop up and take out the instrument. Then, the protective block 43 can be manually separated to insert the external connection cable into the connection port 3 to connect to the instrument. This allows for the detection and location of network faults, find the problem, and make the instrument more flexible. It is convenient for workers to operate with their hands free and improves the detection efficiency.

[0022] Furthermore, such as Figure 2 - Figure 4As shown, the right-side fixing component 5 includes a through groove 51 and a bracket 53. The through groove 51 is opened on the right side wall of the housing 1. A locking block 52 is slidably installed inside the through groove 51. The bracket 53 is fixedly connected to the right side wall of the housing 1. A pull rod 54 is slidably installed inside the bracket 53. The left end of the pull rod 54 is fixedly connected to the right end of the locking block 52. The other end of the pull rod 54 passes through the right end of the bracket 53 and is fixedly connected to a pull ring 55. A damping spring 56 is sleeved on the surface of the pull rod 54. The left end of the damping spring 56 is fixedly connected to the right end of the locking block 52. The other end of the damping spring 56 is fixedly connected to the inner wall of the bracket 53. Slots 23 are opened on both the left and right sides of the detector body 2. The ends of the two locking blocks 52 that are close to each other are respectively engaged with the inside of the two slots 23. A telescopic sleeve 7 is fixedly connected to the bottom inner wall of the housing 1. A lifting block 8 is fixedly connected to the top of the telescopic sleeve 7. The top of the lifting block 8 abuts against the bottom of the detector body 2. A second damping spring 9 is fitted onto the surface. The upper end of the second damping spring 9 is fixedly connected to the bottom of the lifting block 8, and the other end of the second damping spring 9 is fixedly connected to the inner wall of the housing 1. The main body of the detector 2 is slidably connected to the inside of the housing 1. The locking blocks 52 move away from each other under the pressure of the main body of the detector 2, and the lifting block 8 also continues to descend under the pressure until the locking blocks 52 are aligned with the slots 23. The first damping spring 56 drives the locking blocks 52 to engage with the slots 23, thus fixing the main body of the detector 2 inside the housing 1. When it needs to be removed, pull the pull rings 55 on both sides. The pull rings 55 drive the two locking blocks 52 to move away from each other through the pull rod 54 and move out of the slots 23, thus releasing the fixation. At this time, the second damping spring 9 drives the lifting block 8 to rise, and the lifting block 8 drives the main body of the detector 2 to pop out, so that the worker can take the main body of the detector 2 out of the housing 1 for testing. It is flexible to use, and the worker does not need to hold the instrument all the time during the operation, which makes it convenient to perform other operations.

[0023] The protective component 4 includes a pair of vertical plates 41, both of which are fixedly connected to the top of the main body 2 of the detector. A pair of sliding rods 42 are fixedly connected between the two vertical plates 41. A pair of protective blocks 43 are slidably connected to the surfaces of the two sliding rods 42. Each of the two protective blocks 43 has a mounting groove 44 on one side wall that is close to each other. Magnets 45 are fixedly installed inside the two mounting grooves 44. When the instrument is not in use, the two protective blocks 43 are brought close to each other along the sliding rods 42, and the two opposite magnets 45 attract each other, so that the protective blocks 43 are stuck together and block the top of the connection port 3, preventing external impurities from entering the connection port 3 or the interior of the main body 2 of the detector, thus protecting the instrument and extending its service life. When testing, the worker can manually separate the two protective blocks 43 and insert the external connection cable into the connection port 3 to connect to the main body 2 of the detector, thereby detecting and locating network faults. The structure is simple, the operation is convenient, and the practicality of the device is improved.

[0024] The working principle of this utility model is as follows: In use, the detector body 2 is fixed inside the housing 1 by the cooperation of the locking block 52 and the locking slot 23. The worker can then use the elastic plate 6 to fasten the housing 1 and the instrument to his waist, thus freeing up his hands to perform other operations. When the instrument is needed, the pull rings 55 on both sides are pulled to remove the locking block 52 from the locking slot 23, thereby releasing the fixation. The damping spring 29 drives the lifting block 8 and the detector body 2 to rise, allowing the detector body 2 to be taken out. The protective block 43 is then manually separated, and the external connection cable can be inserted into the connection port 3 to detect and locate network faults and find the problem.
