The invention provides a protection cable skinning knife which comprises a handheld cylinder. A tightening mechanism is arranged on the upper end of the cylinder. The tightening mechanism comprises a ring with an internal thread and a tightening cylinder with an external thread. The ring sleeves the tightening cylinder, and is in matching connection with the tightening cylinder through the internal thread and the external thread. The tightening cylinder is composed of a number of tensioning bars, and extends outward along the upper end of the cylinder to form a cone with tapering bore. The axes of the tightening cylinder and the cylinder are superimposed. Two rod-shaped tools are symmetrically arranged on the upper end of the tightening cylinder, and a tool tip is arranged on the upper end of each tool. A tool rod is arranged on the lower end of each tool. The tool rods and the tensioning bars are hinged. An arc-shaped part is arranged on the front end of each tool tip. An arc-shaped notch with an outward opening is arranged below each arc-shaped part. An arc-shaped blade is formed on the inner side of the upper part of each arc-shaped notch. The arc-shaped blades of two tools are inwardly corresponding. According to the invention, a cable skinning effect is improved; skinning time can be greatly reduced; when skinning is carried out, a cable core wire can be effectively protected from being scratched; the whole protection cable skinning knife sleeves a cable; and the protection cable skinning knife has the advantages of easy use and time and effort saving.

The invention discloses an upward sliding electric folding door. The upward sliding electric folding door comprises a door frame, door plates (3) and a lifting rotation mechanism, wherein the door frame is composed of groove rails (4) on the left side and the right side and a door plate folding box (1) fixed at the top, corresponding guide rails (5) are arranged on the groove rails (4) on the left side and the right side and extend into the door plate folding box (1), the six door plates (3) are mutually hinged, idler wheels (2) matched with the guide rails (5) on the two sides are correspondingly arranged on the two sides of the first door plate, the second door plate and the fourth door plate (31, 32 and 34), the distance between the idler wheels on the second door plate (32) and the top of the corresponding door plate is equal to the distance between the idler wheels on the first door plate (31) and the bottom of the corresponding door plate, the distance between the idler wheels on the second door plate (32) and the bottom of the corresponding door plate is equal to the distance between the idler wheels on the fourth door plate (34) and the bottom of the corresponding door plate, and bottom idler wheels (7) matched with the guide rails (5) are arranged on the two sides of the bottom of the sixth door plate (36). After the structure is adopted, the upward sliding electric folding door has the advantages of being simple and reasonable in structure, convenient to operate and use, small in occupied space, good in anti-theft performance and the like.

The invention discloses a device making ship navigation easy. The device comprises a plurality of rotatable Bernoulli effect plates arranged on the outer side of the bottom of a ship body, wherein theBernoulli effect plates are perpendicular to the bottom of the ship body, one sides of the Bernoulli effect plates are planes, and the other sides of the Bernoulli effect plates are arc surfaces protruding outwards. According to the device, the Bernoulli effect plates are arranged at the bottom of the ship body, so that the boosting effect on a ship in the navigation can be achieved, and the fuelconsumption of the ship in the navigation is saved.
