[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 5 As shown, the utility model provides a handheld optical time domain reflectometer, including an optical time domain reflectometer body 1, the upper end of the optical time domain reflectometer body 1 is fixedly connected with a fixing component 1 3, the upper end of the optical time domain reflectometer body 1 is fixedly connected with a fixing component 2 4, the upper end of the optical time domain reflectometer body 1 is fixedly connected with a fixing component 3 10, the lower end of the optical time domain reflectometer body 1 is fixedly connected with a supporting foot 2, the interior of the supporting foot 2 is fixedly connected with a damper 7, the rear end of the damper 7 is fixedly connected with a spring 8, the interior of the supporting foot 2 is fixedly connected with a fixing shaft 2 9, the interior of the fixing component 1 3 is movably connected with an elastic protective film 5, and the upper end of the elastic protective film 5 is fixedly connected with a magnetic suction sheet 6.

[0023] Through the telescopic structure composed of the damper 7, the spring 8 and the fixed shaft 9, four sets of telescopic structures are evenly distributed on each surface of the supporting foot 2. The telescopic structure can adjust the height and level according to actual needs to ensure that the machine maintains a good balance state. This adjustment ability enables the machine to remain stable under different working conditions and improve work efficiency.

[0024] There are four supporting legs 2 respectively located at the four corners of the lower end of the optical time domain reflectometer body 1, and the outer layer of the supporting legs 2 is an elastic steel sheet.

[0025] The four-corner distribution and fixing can effectively improve the stability of the optical time domain reflectometer body 1, making the optical time domain reflectometer body 1 more solid and more stable when placed.

[0026] The three surfaces of the support foot 2 away from the main body 1 of the optical time domain reflectometer are all provided with telescopic structures composed of a damper 7, a spring 8 and a fixed shaft 9, and each surface of the support foot 2 is evenly distributed with four groups of telescopic structures.

[0027] The damper 7, the spring 8 and the fixed shaft 9 form a telescopic structure, and each surface of the support foot 2 is evenly distributed with four sets of telescopic structures. The telescopic structure absorbs the kinetic energy of the collision when the optical time domain reflectometer body 1 falls to the ground or collides.

[0028] Among them, the fixed axis 2 9 is located at the center of the spring 8 , the spring 8 is located between the damper 7 and the inner wall of the supporting foot 2 , and the length of the damper 7 is smaller than the length of the fixed axis 2 9 .

[0029] Because the length of the damper 7 is less than the length of the fixed shaft 9, the damper 7 will provide sufficient support to achieve a stabilizing effect.

[0030] Among them, the shape of the fixing component 1 3 is fan-shaped, and the shapes and sizes of the fixing component 1 3 , the fixing component 2 4 and the fixing component 3 10 are exactly the same.

[0031] The fan-shaped shape can better adapt to complex movement trajectories and load-bearing requirements, and is conducive to the movement and closure of the elastic protective film 5.

[0032] Among them, the left side of the fixing component 1 3 and the right side of the fixing component 3 10 are provided with movable grooves of the same shape and the same depth.

[0033] It is used to fix the elastic protective film 5 and limit the moving track of the elastic protective film 5 .

[0034] The interior of the second fixing component 4 is provided with an active hole having the same shape and size as the active groove.

[0035] This is beneficial to the fixation and movement of the elastic protective film 5 and limits the movement track of the elastic protective film 5 .

[0036] Among them, the elastic protective film 5 is movably connected in the movable groove and the movable hole, the elastic protective film 5 has two ends respectively located at the front and rear ends of the movable groove, and the magnetic suction sheets 6 have four ends respectively located at the upper end of the elastic protective film 5 and distributed at the left and right ends.

[0037] This is beneficial to connecting and fixing the elastic protective membrane 5 , and enhancing the stability of the elastic protective membrane 5 .

[0038] The working principle and use process of this utility model:

[0039] When the handheld optical time domain reflectometer is needed, the elastic protective film 5 is first opened. Figure 1The elastic protective film 5 is shown in an open stacking state, so that the adsorbed magnetic suction sheet 6 is separated, and the elastic protective film 5 is folded and contracted along the movable hole inside the fixing component 2 4, the movable groove of the fixing component 1 3 and the fixing component 3 10, and is respectively placed at the bottom of the front and rear ends of the movable groove of the fixing component 1 3. At this time, the connection line part of the upper end of the optical time domain reflectometer body 1 is exposed. According to actual needs, the line to be inspected is connected. During the connection process, it may be inconvenient to hold the optical time domain reflectometer body 1. At this time, the optical time domain reflectometer body 1 can be placed on the ground or other planes, or a collision may occur during the hand-held operation. The fixed shaft 2 9 inside the supporting foot 2 shrinks toward the inside of the damper 7, and the elastic steel sheet on the surface of the supporting foot 2 is deformed. The spring 8 shrinks at the same time to reduce impact and vibration. The spring 8 can absorb and reduce impact and vibration, and reduce the possibility of damage to the optical time domain reflectometer body 1. After the inspection is completed, the elastic protective film 5 is pulled up along the movable hole inside the fixing component 2 4, the movable groove of the fixing component 1 3 and the fixing component 3 10, and the magnetic suction sheet 6 adsorbs and fixes the docking hole at the vertex for protection.
