[0036] A flip support assembly 7, wherein the flip support assembly 7 is arranged outside the housing 1;

[0037] The clamping buffer assembly 4 includes an inner partition 4-1, which is arranged in the outer shell 1. A connecting groove 4-2 is provided on the surface of the inner partition 4-1. A supporting spring 4-3 is provided in the connecting groove 4-2. The upper end of the supporting spring 4-3 is connected to a sleeve 4-4. The sleeve 4-4 is mounted on the bottom of the resistance tester body 2. A rectangular groove 4-5 is provided at the top of the outer shell 1. A threaded hole 4-6 is provided in the rectangular groove 4-5. An adjusting screw 4-7 is screwed and connected in the threaded hole 4-6. The lower end of the adjusting screw 4-7 is rotatably connected to a clamping plate 4-8. The clamping plate 4-8 is attached to the top of the resistance tester body 2.

[0038] In this embodiment, in order to achieve the anti-seismic protection effect for the resistance tester main body 2, a clamping buffer component 4 is designed, and an inner partition plate 4-1 with two connecting grooves 4-2 is arranged inside the outer shell 1, and a supporting spring 4-3 is arranged in the connecting groove 4-2. A sleeve 4-4 is arranged on the upper end of the supporting spring 4-3, and the resistance tester main body 2 can be inserted into the sleeve 4-4, and the support spring 4-3 can be used for downward buffering to achieve the anti-seismic effect. A rectangular groove 4-5 and a threaded hole 4-6 are opened on the top of the outer shell 1, and an adjusting screw 4-7 is screwed and connected in the threaded hole 4-6. The lower end of the adjusting screw 4-7 is rotatably connected to a clamping plate 4-8. The clamping plate 4-8 can be pressed downward on the top of the resistance tester main body 2 by adjusting the adjusting screw 4-7, so that the support spring 4-3 at the bottom is contracted but not completely compressed, so that the support spring 4-3 retains a buffer space, and has an anti-seismic protection effect.

[0039] Furthermore, the blocking clamping assembly 5 includes a fixed head 5-1, which is connected to one end of the wire 3. Both ends of the fixed head 5-1 are rotatably connected to an isolation sleeve 5-2 through a pin shaft. A first spring 5-3 is connected to the bottom of the fixed head 5-1 inside the isolation sleeve 5-2. A chuck 5-4 is rotatably connected to the isolation sleeve 5-2 through a pin shaft. A second spring 5-5 is connected to the chuck 5-4 and the inside of the isolation sleeve 5-2.

[0040] In this embodiment, in order to achieve the effect of protecting the exposed part when testing the cable, a barrier clamping assembly 5 is designed, and a fixed head 5-1 is connected to one end of the conductor 3, and isolation sleeves 5-2 are rotatably connected to both sides of the fixed head 5-1 through pin shafts, and the isolation sleeves 5-2 can be rotated outward to open, and a first spring 5-3 is connected to the fixed head 5-1 inside the isolation sleeve 5-2, and the two isolation sleeves 5-2 maintain the clamping effect through the elastic force of the first spring 5-3, and a clamp 5-4 is rotatably connected inside the isolation sleeve 5-2, and the clamp 5-4 and the isolation sleeve 5-2 are connected with a second spring 5-5. When the clamp 5-4 clamps the cable, it can be rotated by rotating the connection to cooperate with the cable diameter and the second spring 5-5 to maintain the clamping state, which will not affect the isolation sleeve 5-2.

[0042] In this embodiment, in order to achieve the anti-fall effect, shock-absorbing springs 6-1 are connected at the four corners of the shell 1, and the shock-absorbing springs 6-1 are connected to the contact plate 6-2. When falling, the contact plate 6-2 can squeeze the shock-absorbing spring 6-1 to shrink when it contacts the ground, thereby buffering the impact force and achieving the anti-fall effect.

[0043] Furthermore, the flip support assembly 7 includes a flip cover 7-1, which is rotatably connected to the surface of the housing 1 via a pin, and a side surface of the flip cover 7-1 is rotatably connected to a support plate 7-2 via a pin.

[0044] In this embodiment, in order to achieve the effect of being supported and placed on a desktop at an inclined angle, a flip cover 7-1 is rotatably connected to the front opening of the shell 1, and a support plate 7-2 is rotatably connected to the upper end of the flip cover 7-1. After the flip cover 7-1 is opened, the support plate 7-2 can be flipped backwards and supported on the desktop, so that the shell 1 as a whole is at a certain inclined angle, which is more convenient to use.

[0045] Furthermore, the two isolation sleeves 5 - 2 form a spherical structure as a whole, and the isolation sleeves 5 - 2 are made of insulating material.

[0046] In this embodiment, the spherical structure can increase the cable wrapping area, and the insulating material can improve safety.

[0047] Furthermore, a handle 8 is provided on the top of the housing 1 .

[0048] In this embodiment, the device can be carried by the handle 8, which is at the top for easy grip.

[0049] Furthermore, the overall structure formed by the flip cover 7 - 1 and the support plate 7 - 2 is the same as the opening structure of the housing 1 .

[0050] In this embodiment, the flip cover 7 - 1 and the support plate 7 - 2 form a complete front cover, which can seal the opening of the housing 1 when closed.

[0051] Before use, place the resistance tester body 2 into the sleeve frame 4-4 in the outer shell 1, then turn the adjusting screw 4-7 at the top to move downward so that the clamping plate 4-8 is pressed on the top of the resistance tester body 2, and the wire 3 is placed in the space between the bottom of the outer shell 1 and the inner partition 4-1. It is carried by the handle 8. When operating, open the flip cover 7-1 outwards and continue to rotate the support plate 7-2, place it on a desktop or the ground, support it on the bottom plate through the support plate 7-2, take out the wire 3 and insert it into the resistance tester body 2, press the isolation sleeve 5-2 to open, clamp the chuck 5-4 on the cable, and after loosening, the isolation sleeve 5-2 will wrap the cable inside, and then open the resistance tester body 2 for testing.
