DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] Example 1: Please refer to Figures 1 to 4As shown, it includes an intermediate positioning block 1, an upper positioning block 2 and a lower positioning block 3. The upper and lower surfaces of the intermediate positioning block 1 are symmetrically provided with a first upper semicircular positioning groove 13 and a first lower semicircular positioning groove 14. The two sides of the intermediate positioning block 1 are vertically penetrated with a first bolt hole 11, and the second bolt hole 12 is longitudinally penetrated; the lower surface of the upper positioning block 2 is provided with a second lower semicircular positioning groove 22 corresponding to the first upper semicircular positioning groove 13; the upper surface of the lower positioning block 3 is provided with a second upper semicircular positioning groove 32 corresponding to the first lower semicircular positioning groove 14; the upper positioning block 2 and the lower positioning block 3 are respectively connected to the intermediate positioning block 1 by bolts; the first upper semicircular positioning groove 13 cooperates with the second lower semicircular positioning groove 22, and the first lower semicircular positioning groove 14 cooperates with the second upper semicircular positioning groove 32 to form installation grooves for wiring harnesses to be placed. In this embodiment, the upper and lower surfaces of the intermediate positioning block 1 are respectively provided with two semicircular positioning grooves, that is, four wiring harnesses can be fixed at the same time, so that the wiring harnesses are isolated from each other. It can be understood that the number of semicircular positioning grooves on the intermediate positioning block 1 can be set according to actual conditions.

[0022] In this embodiment, the upper positioning block 2 and the lower positioning block 3 are respectively provided with a third bolt hole 21 and a fourth bolt hole 31 corresponding to the first bolt hole 11 .

[0023] In this embodiment, the middle positioning block 1 is connected to the support plate nut 5 by means of bolts passing through the second bolt holes 12 .

[0024] In this embodiment, in order to protect the wire harness and prevent the wire harness from being worn, a protective pad is provided in each positioning groove. The protective pad can be provided by arranging a fluorosilicone rubber tape or an insulating self-adhesive tape in each positioning groove.

[0025] like Figure 5 and Figure 6 As shown, before the installation of the utility model, it is necessary to open the wiring harness through holes and installation holes on the structural member 6 according to the number and arrangement position of the wiring harness 7.
