However, the transformer of the multifunctional plastic repairing machine is arranged on the power box, and most of the power boxes are made of metal parts, which increases the production cost, is large in size, and is not portable; meanwhile, in order to facilitate the operation of the handle, the power box is usually The longer output lead is connected to the horn on the operating handle so that the loss on the wire is large.

In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a portable plastic repair machine with a small size to reduce production cost and wire loss.

The technical solution adopted by the present invention to solve the technical problem is: an portable plastic repairing machine, comprising an operating handle, the front end of the operating handle is provided with a welding head for energizing and heating, and the operating handle is provided with a transformer set. The transformer group is composed of at least two transformer connections, the output end of the transformer group is connected to the fusion welding head, and the input end of the transformer group is externally connected to the power source through the lead wire.

Preferably, the transformer bank is constructed by four transformer connections; as another preferred mode, the transformer bank is constructed of five transformer connections.

As a further improvement of the above technical solution, the operating handle is provided with a control switch for controlling the input power of the transformer group, and the control switch is preferably pressed. The key or dial key is set on the operating handle, which makes it easier to control the power supply and make the operation smoother.

As a further improvement of the above technical solution, the operating handle is provided with a multi-speed adjusting knob for adjusting the output voltage and current, which is connected to the transformer group, and the multi-speed adjusting knob adjusts the output current voltage by using the number of transformers that change the access circuit. .

As a further improvement of the above technical solution, a wire is connected between the transformer set and the fusion welding head, and the outer diameter of the wire is not less than 3.2 mm, and a large current can be passed to facilitate electrothermal welding.

As a further improvement of the above technical solution, the portable plastic repairing machine further comprises a tooling head for screeding plastic mounted on the welding head, the tooling head is flat or shovel-shaped, and the setting of the tooling head is The plastic repairing machine can be used for both nailing and electrothermal smoothing operations, and can be used in one machine.

As a further improvement of the above technical solution, the outer diameter of the connecting end of the welding head and the operating handle is the largest, and the outer diameter of the welding head is gradually decreased, so that the tooling head is sleeved on the outer thin welding head. It is not easy to loosen and the connection is stable.

The beneficial effect of the creation is that the portable plastic repairing machine directly installs the transformer set on the operating handle, eliminating the original power box accessories, reducing the production cost, the whole machine is small in size and easy to carry; the transformer group setting In the operating handle, the distance between the output end of the transformer group and the welding head is also shortened, and the power loss caused by the line loss is reduced, and the energy saving and environmental protection are saved. The plastic repair machine of this creation only It has an operating handle, simple structure, small size, easy to carry, and the function of nailing machine and heating and smoothing tool. When the tooling head is not installed, the nailing can be carried out, and the tooling head can be put on the nailing after the nailing, and the voltage and current can be switched through the shifting, which can be used for electric heating and smoothing of the plastic, and is convenient to use.
