Detailed Description

The self-rotating LEEP knife provided by the present invention will be described in further detail and fully with reference to the following examples. The following description of the embodiments is merely exemplary in nature and is in no way intended to limit the invention.

A self-rotating LEEP knife comprises a knife handle 1, a knife bar 2 and a knife head 3 which are connected in sequence. The knife handle 1 is of a structure with a cavity, the knife handle 1 is in an oval shell shape, and the knife handle is insulated from the outside. The oval shape is smooth, and the grabbing and the operation are flexible and comfortable.

The cutting head 3 is an annular electrode cutting ring, and the cutting head 3 has conductivity. One end of the cutter bar 2 is fixedly connected with the cutter head 3, and the other end of the cutter bar penetrates through the end part of one end of the cutter handle 1 and then enters the cavity.

A motor 4 is arranged in an inner cavity of the cutter handle 1, and the motor 4 is connected with one end of the cutter bar 2 in the cavity. An electrode plate 8 is further arranged on the inner wall of the cavity of the tool handle 1, the electrode plate 8 is in contact with the tool bar 2, and the electrode plate 8 is located between the motor 4 and the bearing 6. The insulating layer 5 is arranged outside the cutter bar 2, and specifically, the insulating layer 5 covers the rest parts except the part contacting the electrode plate 8 and the part connecting the cutter head 3 outside the cutter bar 2. The motor 4 is electrically connected with an external power supply through a power line, and the electrode plate 8 is electrically connected with the external power supply through the power line.

One end of the knife handle 1 is connected with the knife bar 2 through a bearing 6, namely the bearing 6 is arranged between the knife handle 1 and the knife bar 2. Specifically, the cutter bar 2 penetrates through an inner ring of the bearing 6, and an outer ring of the bearing 6 is sleeved with the end part of the cutter handle 1, so that the cutter bar 2 and the cutter handle 1 can rotate relatively through the bearing 6. Preferably, the bearing 6 is connected to the contact insulation layer 5 outside the tool holder 2, and the motor 4 is also connected to the insulation layer 5. The power lines of the motor 4 and the electrode plate 8 penetrate through the knife handle 1, and a sealing ring is arranged between the power lines and the knife handle 1. Sealing plates are arranged at two ends of the bearing 6. The inner cavity of the knife handle 1 is in a sealed state, so that external impurities are prevented from entering the inner cavity and affecting the internal structure.

And a motor switch 9 for controlling the starting and stopping of the motor 4 and an electrode plate switch for controlling the connection and disconnection of the electrode plate 8 are arranged on the shell of the knife handle 1. When the motor 4 is started, the motor 4 drives the cutter bar 2 to rotate, thereby driving the cutter head 3 to rotate. The middle part of the cutter rod 2 is supported by the middle parts of the electrode plates 8 and the cutter handle 1, so that the multi-supporting-point support is realized while the conduction, the sealing and the transmission are realized, the eccentric rotation of the cutter rod 2 is avoided, the accurate rotation of the cutter rod 2 is realized, and the cutter head 3 can be accurately aligned.
