Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

For present general wall paper sword or collude the problem that the sword is not suitable for oil charge cable protective sheath use, the utility model particularly provides an oil charge cable is with cutting the skin sword, this skin sword of cutting can be used to the protective sheath of cutting the oil charge cable, and the internal component of cutting the process and can not harm the oil charge cable avoids causing the secondary damage at the in-process of overhauing the oil charge cable. For further explanation of the structure of the present invention, the following detailed description is made with reference to the accompanying drawings:

referring to fig. 1 and 2, a skinning knife for oil-filled cables is characterized by comprising a handle part 1, a branch head part 2, a nose part 3, a cutting edge 4 and a cutting edge 5.

The handle-shaped portion forms a handle body for gripping. In this embodiment, the handle is a plate-shaped member with a uniform thickness, and the thickness is designed based on the grip comfort. The upper and lower edges of the pathology are designed to be curved to promote grip comfort. The upper part of the handle-shaped part is provided with a hooking part which protrudes upwards, and the hooking part is used for facilitating the pulling of the handle-shaped part to exert force. The handle-shaped part is provided with a groove cavity 6, the handle-shaped part is provided with a cover plate 7 for covering the groove cavity, namely, a rectangular groove is formed in one end face of the handle-shaped part, the rectangular cover plate is mounted at the opening of the groove through a screw, the groove cavity is formed in the groove, and a spare blade can be stored in the groove cavity.

The branch head part is positioned at the lower part of the front end of the handle-shaped part and forms a supporting bulge; the nose raising part is positioned at the front end of the handle-shaped part, and the nose raising part is positioned on the side of the nose supporting part. The lower edge of the warped head is higher than the supporting bulge of the branch head in the horizontal height under the state that the branch head is supported at the inner side part of the oil filling cable. The top of the nose portion forms a cutting edge, the cutting edge is installed in the cutting edge, and the cutting edge faces the opening direction of the cutting edge. In this embodiment, specifically, the extensions of the branch head portion and the tilted head portion form an arc-shaped edge, and the support protrusion of the branch head portion is an outer edge portion of the arc-shaped edge. The branch head part and the tilting head part form a hook-shaped structure at the front end of the handle part, and the cutting edge is positioned in a hook opening of the hook-shaped structure. The branch head part and the warped head part are of an integrated hook-shaped structure. The integrated hook formed by the branch head part and the warped head part comprises a hook-shaped base integrated with the handle part and a hook-shaped pressing plate 9 connected with the hook-shaped base 8, a blade is clamped between the hook-shaped base and the hook-shaped pressing plate, the blade is provided with a cutting edge, and the hook-shaped base is further provided with a positioning column for the blade. Furthermore, a limiting protrusion is arranged at the front end part of the handle-shaped part, and a limiting groove which is embedded and clamped with the limiting protrusion is arranged at the rear part of the hook-shaped pressing plate. The hook-shaped base and the hook-shaped pressure plate are connected through screws.

According to the skin scratching knife provided by the technical scheme, paraffin removal oil in an oil-filled cable is discharged completely when the skin scratching knife is used, the skin scratching knife is used from one end of the cable, the sharpness of a blade is firstly checked when the skin scratching knife is used, if the blade is broken during outgoing, a cover plate of a handle-shaped part is opened, a new blade is taken out, and a hook-shaped pressing plate is used for replacing the blade. The replaced old blade is stored in the slot cavity, so that subsequent polishing and repairing are facilitated.
