Detailed Description

The utility model is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.

Referring to fig. 1 and 2, the present utility model provides a technical solution: the utility model provides a combination formula wiring groove, including last groove 1 and lower groove 2, both are independent part, go up the cross section of groove 1 and lower groove 2 and be the cell type, go up the open side cover of groove 1 and establish in lower groove 2, go up the both sides of groove 1 and seted up draw-in hole 11, the outside rotation of lower groove 2 is connected with the chuck 3 that cooperates with draw-in hole 11 and use, the limit 31 of stepping down has been seted up to chuck 3's periphery wall, chuck 3 rotates its outer arc limit and can get into draw-in hole 11 after, go up groove 1 and 2 fixed connection down at this moment, reverse control chuck 3 rotates to the limit 31 of stepping down and draw-in hole 11 when being located the outside of draw-in hole 11, go up groove 1 and lower groove 2 can be separated easily.

In this embodiment, the two side walls of the lower groove 2 are respectively welded with the ear plate 21, the lower end face of the chuck 3 is welded with the positioning shaft 32 rotationally connected with the ear plate 21, and the two further side walls of the lower groove 2 are provided with the yielding baffle holes 22 cooperatively used with the chuck 3, which plays a role in preventing the ear plate 21 from deforming, that is to say, when the lower groove 2 has a tendency of moving outwards, the yielding baffle holes 22 limit the chuck 3.
