The invention discloses a cleaning tool and a balancing vehicle for cleaning a balancing vehicle. The balancing vehicle comprises a housing, and the cleaning tool is arranged on the housing. The cleaning tool is arranged on the shell of the balancing vehicle, as that balancing vehicle can be carried with clean tools at any time and anywhere, the balancing vehicle can be cleaned with clean tools atany time and anywhere according to the needs, and the dilemma that a user of the balancing vehicle cannot find a suitable cleaning tool when the balancing vehicle needs to be cleaned in the process of outdoor use of the balancing vehicle is avoided. In addition, when the balancing vehicle is impacted, if the impacted part is the housing covered by the cleaning tool, the cleaning tool will cancelout a part of the impacted external force, thereby reducing the force impacting the housing and protecting the housing.

The invention discloses a spectacle frame mold structure. The spectacle frame mold structure comprises a front mold frame (1) and a rear mold frame (2), and is characterized in that a front mold plate (3), a rear mold plate (4) and an eyeglass frame mold core (5) which are used for forming a spectacle frame are arranged between the front mold frame (1) and the rear mold frame (2), and a demolding device (6) used for enabling the eyeglass frame mold core (5) to move linearly and then rotate to be demolded out of the spectacle frame (100) during mold disassembling is arranged between the eyeglass frame mold core (5) and the rear mold plate (4). The spectacle frame mold structure is simple and low in cost, the spectacle frame after injection molding has no any damage after demolding, and the quality is stable.

The invention discloses a sealing cover of a steering lever of a walking vehicle and a walking vehicle. The walking vehicle comprises a vehicle body and a steering lever for controlling the travelingdirection of the walking vehicle. The first opening and the second opening are openings of an inner space of the steering lever. The steering lever comprises a sealing cover, wherein the sealing covercomprises a first sealing cover and a second sealing cover, and the first sealing cover is connected with the second sealing cover; The first sealing cover is provided with a first housing and a first inner housing. The second cover is provided with a second outer shell and a second inner shell, and the first inner shell is provided with a clamping member; The first housing and the first openingare coincident in shape, and the second housing and the first opening are coincident in shape; The second inner housing extends toward the outer direction of the second housing and protrudes from thesecond housing. The first housing seals the first opening by a snap joint, and the second housing seals the second opening by a second inner housing. Since the second inner housing extends in the outer direction of the second housing and protrudes from the second housing, the second inner housing can abut against the inner wall of the steering lever, so that the sealing cover is not easily turnedup and the installation of the sealing cover is easy.

The invention provides an automatic wire arranging system comprising a work table board and at least one wire arranging work group arranged on the work table board; the wire arranging work group comprises a conveying device, a jacking and shifting module group, an insulating layer detaching module group and a wire arranging and cutting module group; the specific number of the wire arranging work group is decided according to actual production requirements; the following modes of configuration are feasible for satisfying different requirements: only one wire arranging work group is put in place, a plurality of wire arranging work groups are connected in series, and a plurality of wire arranging work groups are connected in parallel; wire material is conveyed onto a work position to be jacked via the conveying device, the wire material is shifted to a work position to be processed via the jacking and shifting module group, part of an insulating layer on the wire material is detached via the insulating layer detaching module group in such a way that a wire core of certain length is exposed, the wire core of the wire material is subjected to wire arranging and cutting operation via the wire arranging and cutting module group, whole processes are finished via machines without manual labor, and work efficiency can be greatly improved.

The invention relates to a production process of yarn-dyed fabric, which includes the following steps: S01, dyeing the yarn: first winding the original yarn on a plastic reel to form a loose tube for dyeing, and then loading the loose tube into a sarong On the yarn bar, hang the sarong into the dyeing vat and start dyeing; S02, warping, wind the dyed yarn on the warp beam through the warping machine; S03, sizing, use the sizing machine to process the yarn Wrapping; S04, drawing in heddles, according to the requirements of fabric process design, thread the warp yarns on the weaving beams into menacea, healds and reed teeth; S05, weaving, weaving through looms; S06, cloth inspection, passed inspection Cloth inspection by cloth machine; S07, code cloth, code cloth by cloth code machine; S08, desizing treatment; S09, inspection. The invention has the advantage of optimizing the follow-up process and improving the overall quality of the cloth.
