In this technical solution, when working, put the automobile oil pipe quick connector between the first tong arm and the second tong arm of the disassembly pliers, so that the pliers on the first tong arm and the tongs on the second tong arm are respectively Align the two force-bearing surfaces of the fastening mechanism on the quick connector, and then firmly grasp the first handle and the second handle, the pliers head on the first pliers arm and the pliers head on the second pliers arm move relatively, the two The clamp head squeezes the two force-bearing surfaces of the fastening mechanism on the quick connector, so that the fastening mechanism is opened to release the fastening mechanism, so that the butt joint oil pipe can be taken out. The dismantling pliers solves the problem that the fastening mechanism on the quick connector has a small stress-bearing surface area and is difficult to apply force by hand, reduces the labor intensity of workers, and improves work efficiency.

The two tong heads are respectively connected with bolts of the first tong arm and the second tong arm, and different tong heads can be replaced according to different types of quick connectors.

As a preference, mutually symmetrical sliding grooves are respectively provided on the front inner side of the first tong arm and the front end inner side of the second tong arm, the bottom of the tong head is provided with a limit block matched with the sliding groove, and the two tongs The limit blocks at the bottom of the head are respectively arranged in the two slide grooves. The pliers head can be inserted and taken out along the chute, and the chute can prevent the pliers head from turning freely.

Preferably, the cross-sectional shape of the chute is consistent with the cross-sectional shape of the limit block, both of which are isosceles trapezoidal. The chute can block the limit block, which is convenient for the installation and removal of the pliers.

Preferably, a return spring is provided between the first handle and the second handle, and the two ends of the return spring are respectively connected to the inner surface of the first handle and the inner surface of the second handle. The return spring can make the gripped handle return to the initial position, and can effectively prevent the damage to the dismantling pliers caused by excessive force when the staff operates.

Preferably, the pliers head has a rectangular parallelepiped structure.

Preferably, the areas of the opposite sides of the two pliers are smaller than the area of the force bearing surface of the fastening mechanism on the quick connector.

Preferably, the first handle and the second handle are covered with non-slip rubber sleeves. The anti-slip rubber sleeve plays an anti-slip effect.

The beneficial effects of the utility model are: the operating force on the handle is transmitted to the pliers head through the principle of leverage, and then the fastening mechanism on the quick joint of the oil pipe of the automobile is squeezed to make it open to unfix, so that the butt joint oil pipe can be taken out, solving the problem of The fastening mechanism on the quick connector has a small stress-bearing surface area and the problem that it is difficult to apply force by hand, reduces the labor intensity of the staff, and improves the work efficiency.
