Fig. 1 to 2 show a first embodiment of the utility model, which in this embodiment comprises a square housing 2 and a screw 1 inside the housing 2, the screw 1 being located at the front end inside the housing 2 for connection with a nut in a furniture plate. An extension rod 6 is arranged at the rear end of the screw 1, the diameter of the extension rod 6 is smaller than that of the screw 1, the extension rod 6 penetrates through the rear end of the shell 2, and the combination of the screw 1 and the extension rod 6 is limited in the middle of the shell 2. An internal gear 4 is arranged in the middle of the extension rod 6, and the internal gear 4 can rotate synchronously with the screw 1. The extension rod 6 at the rear of the inner gear 4 is provided with the spring 7, one end of the spring 7 is contacted with the inner gear 4, and the other end is contacted with the spring buckling opening 8 in the shell 2, so that the screw 1 can be compressed towards the rear of the shell 2 after the front end is stressed, and rebound towards the front of the shell 2 after the stress is lost. In order to limit the screw 1 from sliding out to the front of the shell 2, a buckling opening 3 is arranged in the shell 2 between the screw 1 and the internal gear 4, and the inner diameter of the buckling opening 3 is larger than the outer diameter of the screw 1 and smaller than the outer diameter of the internal gear 4. In order to enable the screw 1 to rotate, a stirring gear 5 is arranged on the shell 2 above the inner gear 4, one side gear of the stirring gear 5 is meshed with the end part of the inner gear 4, and the situation that the inner gear 4 is not contacted with the gear on the other side of the stirring gear 5 after moving to the rear end of the shell 2 is ensured. As shown in fig. 4, in order to fix the toggle gear 5 to the housing 2 and enable the toggle gear to rotate, a clamping groove 9 is formed on the circumference of the side surface of the toggle gear 5 to be clamped on the housing 2. The upper surface of the toggle gear 5 is provided with a rotating groove 10 so as to facilitate an installer to rotate the toggle gear 5 by using a tool; the rotating groove 10 includes a straight groove, a cross groove and a plum blossom groove, and the cross groove is taken as an example in this embodiment.
