DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The utility model provides an embodiment: a bolt that prevents falling off and is easy to take out, including a screwing end 1, a limiting barrier 2, a threaded column 3, an auxiliary limiting adjustment bolt 4 and a threaded hole 5. The screwing end 1 is fixedly connected to the upper end of the threaded column 3, and the upper part of the threaded column 3 is evenly provided with a rotation placement groove 7. The limiting barrier 2 is evenly arranged inside the upper end of the rotation placement groove 7. The threaded hole 5 is opened through the middle of the screwing end 1, and the auxiliary limiting adjustment bolt 4 is threadedly inserted into the inside of the threaded hole 5.

[0020] The bottom end of the auxiliary limit adjustment bolt 4 is rotatably engaged with the extrusion disk 6 , so that the extrusion disk 6 can synchronously squeeze and adjust the extrusion adjustment plate 12 .

[0021] The limiting barrier 2 includes a rotating barrier block 8, an extrusion limiting end 9, a rotating shaft 11 and an extrusion adjustment plate 12. The extrusion adjustment plate 12 is fixedly connected to the upper end of the rotating barrier block 8, the extrusion limiting end 9 is fixedly connected to the bottom end of the rotating barrier block 8, and the rotating shaft 11 is fixedly connected to the side end of the rotating barrier block 8.

[0022] A counterweight block 10 is fixedly mounted on the bottom of the rotating blocking block 8 to serve as a counterweight adjustment.

[0023] The rotating shaft 11 is rotatably engaged with the threaded column 3 , and the rotating blocking block 8 is rotatably disposed inside the rotating placement groove 7 .

[0024] The auxiliary limit adjustment bolt 4 is inserted into the interior of the threaded column 3, and the bottom end of the extrusion disk 6 is in extrusion contact with the upper end of each extrusion adjustment plate 12, playing the role of extrusion rotation adjustment.

[0025] Working principle: By clamping the screwing tool and using the screwing end 1, the threaded column 3 can be screwed and inserted for use. When the threaded column 3 is inserted to the specified depth, the auxiliary limit adjustment bolt 4 is screwed and inserted into the threaded hole 5. At this time, the bottom end of the auxiliary limit adjustment bolt 4 and the extrusion disk 6 at the bottom end of the auxiliary limit adjustment bolt 4 are inserted into the interior of the threaded column 3, and the extrusion disk 6 is squeezed and contacted with the upper end surface of the extrusion adjustment plate 12 evenly arranged inside the rotation placement groove 7, so that the rotating spacer block 8 rotates inside the rotation placement groove 7 using the rotating shaft 11, so that the bottom end of the rotating spacer block 8 and the extrusion limit end 9 rotates outward from the inside of the rotation placement groove 7, playing the role of hooking and blocking, thereby preventing the bolt from falling off during use, and when the auxiliary limit adjustment bolt 4 is removed and the threaded column 3 is pulled out, the rotation blocking block 8 and the extrusion limit end 9 are reset to the inside of the rotation placement groove 7, so that the threaded column 3 can be easily removed, and the counterweight block 10 set at the bottom of the rotation blocking block 8 plays the role of counterweight, so that the bottom end of the rotation blocking block 8 and the extrusion limit end 9 are rotated to the inside of the rotation placement groove 7 in the natural state of the rotation blocking block 8, so that the threaded column 3 can be screwed and used normally.
