Problems solved by technology
[0002] At present, the commonly used threading method in home decoration is to use steel wires for threading. There are many disadvantages of using steel wires for threading. When the site situation is complicated and there are many bends, the steel wires are prone to deformation, resulting in an extremely large number and consumption, which increases construction costs.
And threading the wire with steel wire can't control the direction of the wire, which wastes a lot of manpower and material resources

Embodiment
[0040] first step, preparation
[0041] After stripping off the front 5cm length of the wires that need to be worn, tie them to the figure 1 On the pull ring 3 shown, finally put the magnet ball 1 on the wire and put it inside the PVC pipe.
[0042] The second step, start threading
[0043] Turn on the switch 8 of the host, power on the device, hold the handle to move the host, the bottom surface of the host is in contact with the wall, judge the position of the magnet ball 1 through the sound of the sounder 4 on the host, and when it is directly above the magnet ball 1, By adjusting the knob switch, the resistance value of the sliding rheostat 9 is changed, and the current is changed, thereby changing the magnetic induction intensity and increasing the attractive force between the magnet ball 1 and the magnetic ball 1 . After moving the main frame forward, under the action of gravitation, the inner magnet ball 1 will pull the wire instrument to move forward to achieve the pur...

The invention belongs to the field of family decoration and relates to a threading instrument and a threading method. The threading instrument comprises a main machine and a threading mechanism, wherein the main machine comprises a shell, a sounder, a magnetic generation device, a tension sensor and a light spring; the sounder is arranged on the upper end surface of the shell; the magnetic generation device is arranged in the shell and comprises a power supply, an iron rod, a magnetic sensing coil and a slide rheostat; the magnetic sensing coil is wound at the periphery of the iron rod; the tension sensor is connected with the iron rod through the light spring and is also connected with the sounder; the sounder is capable of making sound of different volumes according to detection forces of the tension sensor; the threading mechanism comprises a magnetic ball, a tail line and a pull ring; the magnetic ball can be displaced under the action of the magnetic generation device; one end ofthe tail line is arranged on the magnetic ball; the pull ring is fixed at the other end of the tail line. By adopting the threading instrument, situations of a PVC (Polyvinyl Chloride) pipe in a wallcan be effectively understood, a threading direction can be controlled, and precise threading can be achieved.
Description
technical field [0001] The invention belongs to the field of home decoration, and relates to a threading instrument and a threading method, which are suitable for threading PVC pipes reserved in walls by different household appliances or lines in the general home decoration process. Background technique [0002] At present, the commonly used threading method in home decoration is to use steel wires for threading. There are many disadvantages of using steel wires for threading. When the site situation is complicated and there are many bends, the steel wires are prone to deformation, resulting in an extremely large number and consumption, which increases construction costs. . And threading with steel wire, can't control the advancing direction of line, wasted a lot of manpower and material resources. Contents of the invention [0003] The application provides a threading instrument and a threading method, which can effectively understand the situation of the PVC pipe in the...
