The clamping block is inserted into the limiting groove, so that the connecting shaft is in a stable state in the fixed sleeve under the action of the clamping block.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. The intelligent clamp ammeter can realize, through the setting of the fixing component, that when the clamp ammeter body needs to measure the cable at a high place during use, the clamp ammeter body only needs to be fixed under the action of the base, the fixing frame and the concave frame, and the connecting shaft is connected to the fixing sleeve, and the clamp ammeter body can be lifted under the action of the support rod to make the clamp ammeter body measure the current of the cable at a high place. The staff does not need to climb to a high place through external equipment, which reduces the risk of high-altitude work and avoids the occurrence of safety accidents such as falling. At the same time, the current measurement can be completed quickly, which saves the time of climbing and moving, improves the work efficiency, and is convenient for operation. At the same time, the efficiency of installing and disassembling the fixing component is high. When it is necessary to measure the cable at a high place, first, the clamp ammeter is The ammeter body slides into the fixed frame, and during the sliding process, the clamp ammeter body will squeeze the concave frame, causing the concave frame to squeeze the first connecting rod and the first bevel block, and causing the first spring to deform, causing the first bevel block to squeeze the second bevel block and the second connecting rod, and causing the second spring to deform. When the clamp ammeter body completely slides into the fixed frame, and the outer periphery of the clamp ammeter body contacts the inner side of the concave frame and the base, the first bevel block will squeeze the second bevel block so that the second bevel block will be on the right side of the first bevel block, and the first bevel block can be limited by the action of the second bevel block, so that the clamp ammeter body is in a stable state in the fixed frame. At the same time, the connecting shaft can be inserted into the fixed sleeve, so that the support rod and the fixed frame can be in a stable state, and the clamp ammeter body can be lifted by the action of the support rod to carry out measurement.

[0017] 2. The intelligent clamp meter can be lifted by the support rod when the clamp meter body is needed to measure the cable at a high position. During the lifting process, when the current of the cable needs to be measured, the wrench can be pressed by the pull rod, the pressing plate, the third spring and the second pull ring, and the clamp head can be rotated by the wrench, so that the clamp head is covered on the outer periphery of the cable, thereby avoiding the situation that the clamp meter body cannot be pressed to make the clamp head cover the outer periphery of the cable because the clamp meter body is at a high position. The phenomenon of being surrounded by the cable can be improved by pressing, and the use effect can be improved, and the measurement efficiency can be improved at the same time. The operation is convenient. When the pliers head needs to be put around the cable, the second pull ring is pulled downward, so that the second pull ring drives the pull rod, the disc and the pressing plate to move downward in the support frame, and the disc drives the third spring to deform, so that the wrench can be pressed under the action of the pressing plate, so that the wrench drives the pliers head to rotate. When the pliers head is put around the cable, the second pull ring is released, the third spring is reset, and the disc drives the pull rod and the pressing plate to move upward, so that the pressing plate can release the pressure on the wrench and the measurement can be carried out.

[0018] 3. The intelligent clamp ammeter, through the hand-held mechanism, can be used to measure current by hand-held use of the clamp ammeter body. The staff only needs to wear insulating gloves and insert the three middle fingers of the hand into the hand-held frame. The staff's hand can be fixed under the action of the fixing rod, the connecting plate, the clamp plate and the fifth spring. By fixing the staff's hand, it can not only avoid the fatigue caused by long-term hand-held measurement work, but also avoid the staff from falling when holding the clamp ammeter, ensuring the safety and stability of the clamp ammeter body during measurement work. The clamp ammeter body can be moved forward and backward under the elastic action of the clamp plate and the fifth spring, so as to meet the needs of fixing the hands of different staff members and improve The fixing effect is achieved, and the hand-held frame is easy to install and disassemble under the action of the limit rod, the third pull ring and the fourth spring, thereby improving the use effect and meeting different use scenarios and use requirements. At the same time, the connecting block drives the hand-held frame to rotate around the round rod to make it horizontal, and the rotated connecting block is fixed under the action of the limit rod and the fourth spring, so that the hand-held frame is in a stable state, and the clamp ammeter body can be supported by the hand-held frame. The support can help the clamp ammeter remain stable, especially when reading values ​​during measurement. Stable placement can reduce reading errors and make the operation of the clamp ammeter more convenient, especially when long-term or repeated measurements are required, which can reduce operator fatigue.

[0019] 4. The intelligent clamp ammeter, through the setting of the limiting mechanism, can realize that when it is necessary to use the clamp ammeter body to perform cable measurement on the cable at a high position, the connecting shaft can be inserted into the fixed sleeve, and under the action of the support rod, the current measurement work of the cable at a high position can be performed through the clamp ammeter body. When the connecting shaft is inserted into the fixed sleeve, under the action of the clamp block, the extrusion ring, the telescopic rod and the sixth spring, the connecting shaft can be limited, so that the connecting shaft is in a stable state in the fixed sleeve, so that the clamp ammeter body can be lifted up for measurement work under the action of the support rod. The sixth spring is easy to operate and is convenient for installing and disassembling the connecting shaft, thereby improving the convenience and efficiency of use. When the connecting shaft needs to be inserted into the fixed sleeve, it is only necessary to pull the rectangular plate to the left, so that the rectangular plate drives the extrusion ring and the clamping block to move to the left, and the telescopic rod and the sixth spring are squeezed. At this time, the connecting shaft can be inserted into the fixed sleeve, and the limiting grooves of the connecting shaft and the fixed sleeve correspond to each other. When the insertion is completed, the rectangular plate is released, and the sixth spring is reset, so that the telescopic rod drives the extrusion ring and the clamping block to move to the right, so that the clamping block is inserted into the limiting groove, and the connecting shaft, the fixed block and the supporting rod are in a stable state.

[0034] In actual operation, when the device is used, when it is necessary to measure a cable at a high place, the clamp meter body 1 is first slid into the fixed frame 312.

When the sliding is completed, the third pull ring 44 is released, the fourth spring 43 is reset, and the limit rod 491 is inserted into the slot, so that the connecting block 42 and the hand-held frame 45 are in a stable state. The staff only needs to wear insulating gloves and insert the three middle fingers of the hand into the inside of the hand-held frame 45, and adjust the splint 46, the fixing rod 48 and the fifth spring 47. By squeezing, the staff's hand can be in a stable state under the action of the clamp plate 46, and the clamp meter body 1 can be put on the periphery of the hand to perform measurement work, so as to avoid fatigue caused by long-term holding of the staff for measurement work, and at the same time, it can prevent the staff from dropping the clamp meter body 1 when holding it. When the clamp meter body 1 needs to be placed for measurement work, the connection block 42 drives the hand-held frame 45 to rotate around the round rod 41 to make it horizontal, and the rotating connection block 42 is fixed under the action of the limit rod 491 and the fourth spring 43, so that the hand-held frame 45 is in a stable state, and the hand-held frame 45 can support the clamp meter body 1 under the action of the hand-held frame 45, and the support can help the clamp meter to remain stable.
