The box body comprises an outer box 2 and an inner box 3; the top surfaces of the outer box and the inner box are both open, the bottom surface of the outer box is fixedly connected with a bottom plate 9, and the bottom of the outer box is sealed by the bottom plate.

The inner box is embedded in the outer box and can slide upwards relative to the outer box; interior box middle part is seted up with test line box shape complex section bar inner chamber 4, and in this embodiment, test line box is the same with section bar inner chamber's shape, includes four circle right angles and the bigger circle right angle of an inside sunken radius. And the shape of the outer box is a pentagon surrounded by four straight edges and a bevel edge so as to match the shape of the inner cavity of the section bar.

The inner box is provided with a locking buckle 5, and the test wire box is fixed with the inner box through the locking buckle; in this embodiment, the locking is detained for two, as shown in fig. 1, two locking detains the symmetry and sets up in section bar inner chamber both sides, and the locking is detained 5 and is located the top surface of interior box, and the locking is detained including a turning block, and the one end of turning block is articulated on interior box through the round pin axle, the other end is the expansion end, and the turning block rotates around the round pin axle to the top of section bar inner chamber and fixes the test line box card in the section bar inner chamber.

The outer box is connected with the inner box through a tension sensor; install pilot lamp 6 and grower 7 on the box body, pilot lamp, grower and tension sensor electric connection. Still be provided with the singlechip in the box body, pulling force sensor and singlechip electric connection send the pulling force signal of telecommunication to the singlechip, singlechip and grower and pulling force sensor electric connection, and after the pulling force signal of telecommunication reached and set for the threshold value, singlechip sent signal start pilot lamp and grower. The indicator light and the grower can be arranged according to the actual situation or the actual requirement, and particularly, the indicator light can be positioned on the top surface of the outer box or the top surface of the inner box; the grower may be located on the top surface of the outer box or the top surface of the inner box.
