A billboard seat cover plate is mounted at the upper part of the billboard seat; square sliding blocks matched with the square sliding grooves for use are fixedly connected to the two side faces of the billboard seat cover plate, a T-shaped sliding groove is formed in one end of the billboard seat, a magnetic attraction block is embedded in one end of the T-shaped sliding groove, an end opening is formed in one end of the billboard seat and located in one side of the T-shaped sliding groove, and a movable groove is formed in one endof the billboard seat. By means of the designed mounting structure, the billboard can be rapidly installed, so that the billboard is convenient to disassemble when being damaged or needing to be cleaned, meanwhile, the mounting structure is ingenious, and the billboard can be stably fixed.

The invention relates to a cutting device, in particular to an automatic noodle cutting device. The technical problem is how to design an automatic noodle cutting device that can replace the manual cutting of dough into dough, is labor-saving and has high working efficiency. An automatic noodle cutting device, comprising: a bottom plate, one side of the bottom plate is fixed with a placing plate, and one side of the bottom plate is symmetrically spaced with grooves; a guide rod, the guide rod is symmetrically fixed to the bottom plate one side of the bottom plate, which is located on both sides of the placing plate. In the present invention, by placing the dough on the placing plate and starting the servo motor, the cutter can move up and down to cut the dough into noodles, and through the cooperation of the moving components, the cutter can move a certain distance to the right each time it cuts , that is, the dough is fully cut into noodles, and there is no need to manually cut the dough into noodles, which is labor-saving and work efficiency is high.

The invention relates to a method for connecting harmonica reeds, which belongs to the technical field of musical instruments. It is characterized in that: the seat plate is made of stainless steel, and the spring cap of the reed and the seat plate are fixed by welding. The specific process steps are as follows: Punch the sound hole longitudinally on the seat plate; spread a long strip of kapok paper horizontally on the surface of the sound hole on the seat plate to cover or partially cover the sound hole on the seat plate, and leave the welding position for Lay the kapok paper; insert the reeds one by one into the sound hole on the kapok paper; paste a long strip of adhesive tape on the surface of the kapok paper embedded with the reeds; place the seat plate with the reeds directly on the point Weld at spring cap on welder; remove tape and kapok paper. The invention can not only ensure firm positioning between the reed and the seat plate, reduce the gap between the bottom sound hole and the reed, enable the sound to be pronounced by light blowing, but also reduce the material cost of the seat plate.

The present invention relates to the field of furniture, in particular to a rail-type dining table that can freely splice the desktop, including a guide rail, a support frame, a table top, a shielding mechanism, a clamping mechanism, etc.; A desktop is connected, a shielding mechanism is distributed slidingly connected on the guide rail, and a clamping mechanism is slidably connected in the desktop. Through the block control mechanism and the slider control mechanism, the user manually pulls down the push frame to control the operation of the equipment, adjust the connection between adjacent desktops, and then control the sliding frame and its upper device between adjacent desktops. connections, making this device suitable for dining with larger or smaller groups of people.

The invention relates to a printing method of a manual blue printed fabric, comprising the following steps: (1) fixing a stainless iron plate on a table surface; and (2) paving a cotton fabric to be scratched and printed on the iron plate; covering a manual or laser-etched magnetic polyvinyl chloride (PVC) hollowed-out paper plate on the cotton fabric; fixing one end of the paper plate on the stainless iron plate; scratching and printing dry-resistant paste by a scratcher, and drying. According to the printing method of the manual blue printed fabric, by adopting the magnetic PVC paper, the hollowed-out paper plate can be directly etched by manpower or laser, which is simple and convenient, and the complex process of the conventional manual plate making is greatly reduced and the plate making efficiency is improved; and the moulded plate is easy to store and long in service life. The printing method of the manual blue printed fabric solves the problems of being easy to cause plate pasting, out of register and the like in the conventional manual blue printed fabric printing process.

The invention discloses a device for separating components and parts on a circuit board and a substrate of the circuit board, which comprises a transmission part, a support part, a disassembly part and a guide plate, wherein the transmission part comprises a transmission frame and a transmission band device; the support part comprises a lining base and a support frame which comprises a work bed plate, a left upper beam and a right upper beam; the disassembly part comprises a left disk assembly, a right disk assembly and a transmission mechanism; the left disk assembly comprises a left step shaft, a left guide disk, a left dentiform cutter head and a left elastic limit device; the right disk assembly comprises a right step shaft, a right guide disk, a right dentiform cutter head and a right elastic limit device; and the guide plate is arranged between the transmission band of the transmission part and the left guide disk and right guide disk of the disassembly part. The separation device has strong self-adaptation and high efficiency, and simultaneously removes slicker solder in the disassembly process so as not to need heating and smelting the slicker solder again.

The invention discloses a portable ladder which comprises a ladder body (1) and a plurality of pedal plates (2), wherein the bottom of each pedal plate (2) is provided with at least two inward sunk fixing grooves (3). According to the invention, the ladder can be carried by clamping or fastening the fixing grooves of the pedal plates, the fixing mode is simple, and the ladder can not move by the fixing mode.

The application of the present invention belongs to the technical field of building measuring tools, and specifically discloses a house square measuring ruler based on real estate evaluation, which includes a base, a vertical telescopic part is connected to the base, and a cylinder with piston rods arranged horizontally is arranged on the upper part of the telescopic part. There is a horizontal fixed ruler on the piston rod, and a measuring ruler is horizontally hinged at one end of the fixed ruler. A transparent scale tube is provided along the length of the measuring ruler. The tube is connected with the scale tube and the sleeve tube is filled with fluorescent liquid.
