In the description of the present utility model, it should be noted that, unless explicitly specified and limited otherwise, the terms "connected," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.

The fixing bolt with stable connection shown in fig. 1-4 comprises a bolt body 1, wherein an un-penetrated through groove 3 is formed in the bolt body 1 from the top end downwards, a through hole 2 communicated with the through groove 3 is formed in the side surface of the screw end of the bolt body 1, an elastic plate 7 is fixedly connected to the inner side wall of the through groove 3, a clamping block 8 is fixedly connected to the outer side end of the elastic plate 7, an extrusion block 10 is fixedly connected to the inner side of the elastic plate 7, and a plug block 4 is slidably connected to the through groove 3; after the bolt body 1 is screwed into the wall body, the plug block 4 slides inwards through extrusion, the plug block 4 slides inwards to touch the extrusion block 10, the extrusion block 10 drives the elastic plate 7 to move outwards, the clamping block 8 fixed on the outer side of the elastic plate 7 moves outwards, the clamping block 8 contacts with a fixing hole in the wall body through the clamping block 8, the friction force between the clamping block 8 and the wall body is increased, and then the bolt body 1 and the wall body can be connected more stably.

As shown in fig. 4: the inner wall upper portion fixedly connected with rand 6 of wearing groove 3, the draw-in groove 5 that matches with rand 6 is seted up in the outside of chock 4, and the upper portion inside wearing groove 3 is seted up to rand 6, and the draw-in groove 5 has been seted up to the lateral wall of chock 4, and the draw-in groove 5 corresponds the setting with the position of rand 6, and chock 4 is spacing by the position of rand 6 when not using, and rand 6 is elasticity setting, and rand 6 receives the extrusion and produces deformation when extruding chock 4, and chock 4 can inwards slide.
