The device has the advantages that the structure is simple and scientific, and the vision requirement is low; the novel method and structure are adopted, the weight is light, the production cost is low, the hole effect of the needle hole is utilized, operation is easy and fast, needle threading is efficient, and the problem that due to the fact that the needle hole is small, aiming is difficult, the texture of a needle thread is soft, and the thread end is fluffy, scattered and prone to splitting, it is very difficult to accurately penetrate the thread end into the needle hole is solved.

The invention belongs to the field of large-scale steel pipe transportation, and particularly relates to a large-scale steel pipe temporary transfer device for construction, which includes a door frame, a holding board A, a holding board B, a worm and a worm wheel, etc., wherein a moving device is installed on the door frame; the present invention Because it only acts on one end of the large steel pipe, it is small in size and light in weight, easy to operate, and free to turn; because it is small in size and light in weight, the space occupied by the present invention is small, and it is convenient after the use of the present invention Collection and safekeeping. In addition, after the holding plate A completely covers the large steel pipe, the two ends of the holding plate A are equal to the overlapping parts of the door frame, so that the force on both ends of the holding plate A is even, and it forms an effective support for the large steel pipe; this structure The holding plate A is not easily deformed under the long-term pressure of the large steel pipe, the service life of the holding plate A is prolonged, and the maintenance cost of the equipment is reduced.

The invention discloses a needle and thread coil. The needle and thread coil comprises a hollow paper cylinder and a needle and thread. A plastic block with the hunch-up cambered surface is pasted to one side of the inner wall of the hollow paper cylinder, and a soft leather layer is compounded on the cambered surface; a transverse shallow groove providing the positioning and limiting functions for the needle and thread is formed in the surface of the soft leather layer, and the hollow paper cylinder is provided with a feeding groove for needle and thread passing and a needle-and-thread-end fixing clamping groove. When the needle and thread coil is used, a needle hole is lightly pressed on the needle and thread on the soft leather layer and moves back and forth and left and right, the needle and thread can be hunched up at the needle hole, and needle threading can be completed. The needle and thread coil has the advantages that the vision requirement is low; the new method and structure are adopted, the hole effect of the needle hole is adopted, operation is easy and fast and convenient, needle threading is efficient, and the problem that as the needle hole is small, aiming is difficult, the needle and thread is soft in texture, and the thread head is fluffy, divergent and easy to slit, it is difficult that the thread head is accurately threaded into the needle hole is solved; the making cost is low, carrying is convenient, and collection and storage are convenient; needle threading is simple and easy to operate, and the large popularization value is achieved.

The invention belongs to the field of power distribution networks, and particularly relates to a distribution network automatic working platform. The distribution network automatic working platform comprises a cross beam, hook mechanisms and an operation table mechanism. The two hook mechanisms matched with a distribution box support beam are symmetrically arranged at two ends of the cross beam. The distribution network automatic working platform can be folded after use, and is thus convenient to transport and store. Compared with a traditional working platform built through an insulating scaffold, the working platform made of a light insulating material can be built only by two persons, the stability of the working platform is higher than that of a scaffold platform in the working process, and the working platform is not affected by external force and wind force and is of high safety.

The invention belongs to the technical field of mold carrying and particularly relates to a mold carrying device. The mold carrying device comprises supporting mechanisms and adjusting mechanisms, wherein the same sides of the two symmetrically-distributed supporting mechanisms are connected through the adjusting mechanisms, the two symmetrically-distributed adjusting mechanisms are used for synchronously adjusting a distance between the two supporting mechanisms.
