Live working refers to a method of repairing and testing high-voltage electrical equipment without power outages. Electrical equipment needs to be tested, inspected and repaired frequently during long-term operation. In order to avoid power outages for maintenance and ensure normal power supply, live working requires the use of mechanical pliers for live power working. However, when performing live working, the existing mechanical pliers require the operator to hold the mechanical pliers in his hand all the time to prevent them from falling. This not only increases the workload but also prevents the operator from freeing his hands for convenient operation, greatly increasing the difficulty of the operation. Summary of the Invention

[0023] Compared with the prior art, the present invention has the following beneficial effects: the mechanical pliers for live electric power working:

[0024] 1. When working at height, simply snap the quick-release buckle into the handle pull ring and snap the other end into the outer surface of the tool bag. Connect the mechanical clamp to the tool bag via an elastic cord. The elastic cord prevents the mechanical clamp from falling directly to the ground if it is accidentally dropped. At the same time, the elasticity of the elastic cord does not affect the movement of the mechanical clamp during use, reducing the risk of the mechanical clamp falling and injuring people on the ground. It can also solve the dilemma of workers being unable to continue working if the mechanical clamp falls.

[0025] 2. Use the magic tape to attach it to your arm, and insert the quick-release buckle on the other end into the handle pull buckle. The traction rope can be used to protect and restrict the mechanical clamp, so that you can release your hands and operate the mechanical clamp after use. This improves work efficiency while freeing up your other hand to operate, and reduces the chance of dropping the mechanical clamp when picking it up and placing it.

[0026] 3. The ratchet shaft allows the first and second handles to remain in a clamped state after being squeezed, preventing the mechanical clamp from loosening easily and causing parts to fall. At the same time, when not in use, the push rod can be pushed to push and restrict the fixed ratchet shaft, so that the ratchet shaft can be squeezed and fixed by the push of the first spring, allowing the first and second handles to be flexibly opened and closed, making it convenient to adjust the state of the first and second handles;

[0027] 4. When in use, the thread cutting head, thread pliers head, and pointed nozzle head can be inserted into the interior of the first handle and the second handle by pulling the latch, and then releasing the handle to allow the second spring to push the latch, so that the latch can be engaged with the thread cutting head, thread pliers head, and pointed nozzle head to fix the thread cutting head, thread pliers head, and pointed nozzle head, making it convenient to replace tool heads with different functions to achieve different usage methods. Moreover, when the thread cutting head, thread pliers head, and pointed nozzle head are worn, they can be easily replaced without having to replace them as a whole, saving use costs, and can be used for different functions.

[0028] 5. The insulating shell can protect the light-emitting body and the resistor and prevent power leakage, while the light guide cover can guide the light emitted by the light-emitting body so that the light of the light-emitting body can be observed more easily. At the same time, the fixing screw is screwed into the first handle to form a conductor to supply power to the light-emitting body, so that the light-emitting body can emit light after the touch piece is touched, and the conductivity of the first handle can be used to determine whether the circuit is charged.

[0042] The insulating sleeve handle 3 and the anti-skid pattern 4 can increase the anti-skid property when using the mechanical pliers and increase the comfortable feeling when holding.

[0043] The anti-fall mechanism includes: a handle pull buckle ring 17, which is fixedly installed on the outer surface of one end of the insulating sleeve handle 3. A quick buckle head 18 is installed inside the handle pull buckle ring 17, and an elastic rope 19 is fixedly installed on one side of the quick buckle head 18. The other end of the elastic rope 19 is fixedly installed with a quick buckle head 18, and the other quick buckle head 18 is buckled on the tool bag.

[0046] By sticking the magic fixing band 21, the magic fixing band 21 can be fixed to the worker's arm, and the quick buckle head 18 on the other side can be buckled into the handle pull buckle ring 17, so that the tool pliers can be fixed to the worker's arm through the traction rope 20, so that the user can put down the mechanical pliers when he needs to perform the next operation without having to insert them back into the tool bag, reducing the chance of the mechanical pliers falling when taking them out of the tool bag, and facilitating intermittent use.

[0047] A ratchet shaft 5 is installed through the rotating shaft of the first handle 1 and the second handle 2, and the ratchet shaft 5 is rotatably connected to the first handle 1 and the second handle 2. An engaging mechanism is provided between the first handle 1 and the second handle 2, so that the mechanical pliers can tightly clamp objects when in use so that the objects will not fall off.

[0048] The ratchet shaft 5 allows the second handle 2 to move with the ratchet shaft 6 when the first handle 1 and the second handle 2 are rotated, so that the ratchet shaft 6 can be engaged with the ratchet shaft 5, so that the first handle 1 and the second handle 2 will not automatically loosen after clamping the object, causing the clamped object to fall.

[0054] The pulling pin 12 can be conveniently pulled by pulling the lifting rod provided on the outer surface of the pulling pin 12, so that the pulling pin 12 can be retracted into the first handle 1 and the second handle 2, so that the cutting head 14, the clamping head 15, and the pointed mouth head 16 inserted into the first handle 1 and the second handle 2 can be fixed. The pulling pin 12 is pushed back by the second spring 13, so that the pulling pin 12 can be fixed with the cutting head 14, the clamping head 15, and the pointed mouth head 16, so that the tool head of the mechanical pliers can be replaced conveniently, and the cutting head 14, the clamping head 15, and the pointed mouth head 16 do not need to be replaced as a whole after they are worn, thereby saving the cost of use.
