[0023] The embodiments of the present application will be described in detail below with the drawings and examples, so that the realization process of how the present application applies technical means to solve technical problems and achieves technical effects can be fully understood and implemented.

[0024] As shown in Figures 1-4 A positioning tool for facilitating accurate installation of a junction box, comprising a positioning plate 1, both ends of the top of the positioning plate 1 are provided with through holes, two positioning blocks 3 are slidably arranged in the two through holes, the lower end of the positioning block 3 is conical, the axial distance between the two positioning blocks 3 is the same as the axial distance between the connecting ears on both sides of the junction box, and the bottom corners of the positioning plate 1 are provided with magnets 2.

[0025] In use, the positioning plate 1 is adsorbed on the carrier (the carrier is made of iron) where the junction box needs to be installed through the magnets 2, then the position of the positioning plate 1 is adjusted, the positioning block 3 is knocked by a wooden board or a hammer or other heavy objects, so that the positioning block 3 leaves a mark on the carrier, then the positioning plate 1 is taken off from the carrier, the worker aligns the connecting ears of the junction box according to the mark, and finally the junction box is fixed and connected by a flat head self-tapping screw.

[0026] The two positioning blocks 3 are arranged on the positioning plate 1, and the axial distance between the two positioning blocks 3 is the same as the axial distance between the connecting ears on both sides of the junction box, so that the junction box can be quickly and accurately positioned during installation, avoiding the problem of scrapping caused by inaccurate drilling position in the traditional method, and greatly improving the installation efficiency and accuracy; through the design of the magnet 2, the positioning plate can be easily adsorbed on the iron carrier, avoiding the phenomenon of deviation of the positioning hole during positioning.
