There is first end cover.
Further, the first spring is provided in the snail shell body, first spring is against described first
Between end cap and the mounting base, convenient for wooden splice assembling when screw aligned with the threaded hole in nut head.
Further, be provided with locking gear between the screw shell and the mounting base, with prevent screw with
Nut head be spirally connected it is fixed after generate loosening.
Further, the locking gear includes at least one positioning ball, the sidewall upper of the screw shell
It is provided with the quantity steel ball hole equal with the positioning ball, the steel is arranged in the positioning ball correspondingly
In the hole of bead, it is provided with second spring in the steel ball hole, is fixed with second end cover on the outside of the steel ball hole, described
Two springs are against between the second end cover and the positioning ball, are provided on the outer circumference surface of the mounting base more
A location hole being distributed uniformly and circumferentially, when the screw hole in the screw and the nut head is fixed,
In the positioning ball insertion location hole.
Further, the outer surface of the nut head and the screw shell is respectively arranged with external screw thread, described
The lower end of nut head and the upper end of the screw shell be respectively set it is jagged, to facilitate rotating nuts head and screw shell,
But also nut head and screw shell are embedded in securely in wooden splice.
Compared with prior art, the utility model has the advantages that due to nut head and screw shell be embedded in respectively two it is wooden
In splice, and the lower end of screw is fixedly installed mounting base, and the first magnet is fixedly installed in mounting base, passes through magnetic control
Device drives the rotation of the first magnet, so that screw be driven to rotate upward or downward, realizes that screw and being spirally connected for nut head are fixed or torn open
Point, that is, the assembling or fractionation of two wooden splices are realized, rapid and convenient is dismounted, reduces the labor intensity of operator,
Production efficiency is improved, and nut head and screw are hidden in wooden splice, improves the beauty of wooden completed knocked down products
Degree.

Specific embodiment
The utility model is described in further detail below in conjunction with figure embodiment.
As shown, a kind of magnetic control hidden screw, including the nut head being embedded in two wooden splices 100,200 respectively
1 and screw shell 2, threaded hole 11 is provided in nut head 1, and screw 3 and the first spring 4, snail shell are provided in screw shell 2
The upper end of body 2 is provided with through-hole (not marking in figure), and screw 3 is pierced by through-hole upwards, and the lower end of screw 3 has been wholely set mounting base
31, the first magnet 5 is fixedly installed in mounting base 31, and the lower end of the lower ending opening of screw shell 2, screw shell 2 is fixedly connected
There is first end cover 21, the first spring 4 is against between first end cover 21 and mounting base 31, sets between screw shell 2 and mounting base 31
It is equipped with locking gear, locking gear includes two symmetrical positioning balls 7, and the sidewall upper of screw shell 2 is provided with quantity
