[0007] A connecting tube with a limiting hole is arranged at the end of the second clamp body away from the temperature measuring device, and the limiting holes are arranged at intervals along the length direction of the connecting tube. A sliding rod with a limiting block arranged on the circumferential side wall is arranged at the end of the first clamp body away from the temperature measuring device, and the sliding rod can be embedded in the interior of the connecting tube so that the limiting block corresponds to the limiting hole.

When the first clamp body and the second clamp body are close to each other, the measuring device fits tightly against the cable surface for detection. When the measuring device fits against the display screen to display the measured data, the sliding rod is slid to the appropriate position so that the limit block enters into the nearest limit hole.

[0026] A first gasket 41 is sleeved on the first pliers body 11, and a second gasket 42 is sleeved on the second pliers body 12. When the first pliers body and the second pliers body are gripped and applied with force, the palms of the staff come into contact with the surfaces of the first gasket and the second gasket, thereby increasing the friction when gripping.

[0027] The surface of the first gasket 41 is provided with anti-slip grooves.

[0028] The second gasket 42 is an elastic rubber gasket.

[0029] The first clamp body 11 and the second clamp body 12 both include an arc-shaped clamping portion 31 and a handle portion 32 . The arc-shaped clamping portion 31 connected to the temperature measuring device 14 is disposed at one end of the handle portion 32 , and the two arc-shaped clamping portions 31 are disposed opposite to each other.

[0030] One end of the handle portion 32 away from the arc-shaped clamping portion 31 is connected to an anti-dropping hand strap 5, and the first pliers body and the second pliers body can be conveniently carried by passing the arm through the anti-dropping hand strap.

[0031] A display screen 16 is disposed between the two temperature measuring devices 14 , and the display screen 16 and the temperature measuring devices 14 are connected via a transmission elastic rod 15 .

[0034] A connecting tube 23 with limiting holes 24 is provided at one end of the second clamp body 12 away from the temperature measuring device 14, and the limiting holes 24 are arranged at intervals along the length direction of the connecting tube 23. A sliding rod 21 with limiting blocks 22 arranged on the circumferential side wall is provided at one end of the first clamp body 11 away from the temperature measuring device 14, and the sliding rod 21 can be embedded in the connecting tube 23 so that the limiting blocks 22 are matched with the limiting holes 24.

[0035] The temperature measuring device of the first clamp body and the second clamp body is clamped on the outer wall of the cable, and the sliding rod is allowed to slide in the connecting tube by pressing the limit block, and the angle between the first clamp body and the second clamp body is adjusted to ensure that the temperature measuring device is in close contact with the outer wall of the cable, and the limit block is embedded in the corresponding limit hole, so that the angle between the first clamp body and the second clamp body is fixed, thereby avoiding unstable holding of the person, improving the stability of the contact between the measuring device and the outer wall of the cable, and improving the accuracy of the measurement result.

[0036] A first gasket 41 is sleeved on the first caliper body 11, and a second gasket 42 is sleeved on the second caliper body 12;

[0037] By providing the first gasket and the second gasket, the contact area between the worker and the palm is increased, the friction when holding is increased, and the possibility of the worker dropping the device when holding it, which causes measurement errors in the measuring device, is reduced.

[0038] The second gasket 42 is an elastic rubber gasket.

[0039] The first clamp body 11 and the second clamp body 12 both include an arc-shaped clamping portion 31 and a handle portion 32 . The arc-shaped clamping portion 31 connected to the temperature measuring device 14 is disposed at one end of the handle portion 32 , and the two arc-shaped clamping portions 31 are disposed opposite to each other.

[0040] One end of the handle portion 32 away from the arc-shaped clamping portion 31 is connected to an anti-dropping hand strap 5. The anti-dropping hand strap is provided to increase the portability of the measuring tool and facilitate use by the staff.

[0041] A display screen 16 is disposed between the two temperature measuring devices 14, and the display screen 16 and the temperature measuring device 14 are connected via a transmission elastic rod 15;

[0042] By providing the transmission elastic rod and the display screen, the convenience of transmitting the data to the display screen surface through the transmission elastic rod when the measuring device finishes measuring is improved, and the stability of the measuring device during measurement is improved.

[0043] The first clamp body 11 and the second clamp body 12 are rotatably connected via a rotating shaft 13 .

[0044] The support rod 25 and the sliding rod 21 are coaxially arranged.

[0045] The working principle is:

[0046] When in use, when it is necessary to detect the temperature of the power cable, the staff will hold the first clamp body and the second clamp body with their hands, and the first clamp body and the second clamp body will rotate around the rotating shaft, and then the arc-shaped clamping parts of the first clamp body and the second clamp body will clamp the cable, and then the measuring devices on the first clamp body and the second clamp body will fit on the surface of the cable, and then measure, and the measured data will be displayed on the display screen through the transmission elastic rod;

[0047] When the staff holds the first clamp body and the second clamp body and applies force, the sliding rod slides inside the connecting tube. When the first clamp body and the second clamp body are close to each other, the measuring device is closely attached to the surface of the cable for detection. When the measuring device is attached to the display screen and the measured data is displayed, the sliding rod is slid to a suitable position so that the limit block enters the nearest limit hole.

[0048] When holding the first clamp body and the second clamp body and applying force, the staff's palms come into contact with the surfaces of the first gasket and the second gasket, which increases the friction when holding, and passes the arm through the anti-slip wrist strap to facilitate carrying the device.

[0049] When using the above-mentioned power cable temperature measuring clamp, the temperature measuring device of the first clamp body and the second clamp body is clamped on the outer wall of the cable, and the sliding rod is allowed to slide in the connecting tube by pressing the limit block. The angle between the first clamp body and the second clamp body is adjusted to ensure that the temperature measuring device is in close contact with the outer wall of the cable, and the limit block is embedded in the corresponding limit hole, so that the angle between the first clamp body and the second clamp body is fixed, thereby avoiding unstable holding of the person, improving the stability of the contact between the measuring device and the outer wall of the cable, and thus improving the accuracy of the measurement result.

[0050] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model.
