The invention relates to a winding device, in particular to a straw winding device. The technical problem is how to design a straw braided winding device that can be more convenient for people to wind up the straw rope, has high work efficiency, and the straw rope that is rolled up is also neat. A straw weaving and rolling device, including a base, a support block is fixedly connected to the middle part of one side of the base, a vertical plate is fixedly connected to the edge of one side of the support block, and the bearing seat is embedded and installed on the side far away from the support block. One part of the vertical plate, the shaft is rotatably connected in the bearing seat. In the present invention, by winding the straw rope around all the top blocks, and then pulling the rocker to rotate forward, the top block can be rotated forward to wind up the straw rope. After the straw rope is rolled up, pull the handle to move forward to make the top block Move inward to loosen the straw rope, and then take off the rolled straw rope, so that people don't need to pull the straw rope to wrap it around the tool for winding, which is more convenient and improves work efficiency.

The invention discloses a high-tensile signal transmission reel cable, which comprises a cable body, the cable body contains soft steel wires, a copper wire braid layer and an insulating layer, the copper wire braid layer is provided with soft steel wires, and the copper wire braid The outer surface of the inner layer is covered with an insulating layer, and the outer surface of the cable body is covered with an inner lining layer, and hemp rope is filled between the inner lining layer and the cable body, and the outer side of the inner lining layer is wrapped with a shielding layer, so The inside of the shielding layer is provided with a drain wire, the outer surface of the shielding layer is covered with an outer protective cover, and the outer surface of the outer protective cover is provided with a steel wire braided layer; the insulating layer is made of a highly flexible flame-retardant PVC insulating material, On the premise of ensuring the excellent electrical insulation performance of the cable, the heat resistance, flexibility, flame retardancy and mechanical properties of the cable are guaranteed; the cable in the present invention has good flexibility, tensile resistance and mechanical properties, and can withstand large tensile forces and bend.

The invention discloses a device for winding an aluminum armor tape on a transmission line and an application method of the device. The device comprises a support block, a pressing down block, a tape reel and a connection pin shaft, the pressing down block is matched with the support block to lock the transmission line, and the support block is parallel to two lateral sides of the pressing down block. A concave block is arranged at the front end of the support block, a hollow clamping plate is arranged in the middle of the support block, and a handrail block is arranged at the rear end of the support block. A first cuboid block is arranged at front end of the pressing down block, an arc block is arranged in the middle of the pressing down block, and a second cuboid block matched with the clamping plate in shape is arranged at the rear end of the pressing down block. An aluminum armor tape groove is formed in the tape wheel, an aluminum armor tape fixing device is arranged on the inner wall of the aluminum armor tape groove, a through hole corresponding to through holes in the clamping plate is formed in a tape wheel axle, and round projections centering on the center of the tape wheel are arranged on one side, adjacent to the clamping plate, of the tape wheel. The connection pin shaft fixes one side of the clamping plate, the second cuboid block, the other side of the clamping plate and the tape wheel sequentially via the through hole in one side of the clamping plate, a through hole in the second cuboid block, the through hole in the other side of the clamping block and the through hole in the tape wheel.

The invention provides a microtransformer manufacturing method and the microtransformer. The manufacturing method includes: step 1 providing a terminal base with a fixed winding post; step 2 winding the first coil; step 3 sequentially completing the winding of other coils in the coil group; step 4 removing the winding post; step 5 assembling microtransformer. When the coil is wound, the present invention fixes the lead-out wire of the coil and the terminal of the wiring base together, so that it does not need to be fixed again after the coil is wound, and the operation is convenient and the process is simple.

The invention relates to the technical field of musical instruments, and discloses a portable guzheng finger training device. A hinge shaft is arranged on the piano board, and the left and right ends of the hinge shaft are fixedly connected with the piano board. It is installed at the divided position of the inner bottom of the piano board. There is a winding device on the left side of the piano board. The winding device is installed through the left side wall of the piano board. There is also a cover on the left side of the piano board. The cover is an arc-shaped board. And the upper end of the cover is provided with a movable shaft. This portable guzheng finger training device uses the hinge shaft to change the entire piano board into two parts that can be folded, so that the user can fold the piano board when carrying it. The method reduces its size to make it more convenient to carry. At the same time, the user can also roll up the strings through the winding device to avoid damage or winding of the strings, so that the piano board can be more compact when carried, increasing the the practicality of the device.
