[0007] As a further description of the above technical solution:

[0008] The vertical grooves are provided with four groups, and the four groups of vertical grooves are evenly distributed on the first nut.

[0009] As a further description of the above technical solution:

[0010] The first screw rod, the first nut and the hook are made of stainless steel.

[0011] As a further description of the above technical solution:

[0012] The length of the first screw is ten centimeters, and the diameter of the first screw is one centimeter.

[0013] As a further description of the above technical solution:

[0014] The length of the first nut is five centimeters, and the first nut is located at the top end of the first screw rod.

[0015] As a further description of the above technical solution:

[0016] The length of the internally threaded tube is three centimeters.

[0017] The utility model has the following beneficial effects:

[0018] 1. In the utility model, the first screw is rotated and screwed into the first nut, and then the first nut begins to expand, thereby achieving a fast connection with the wall. Then, a hook is provided on the first screw, so that it is convenient to hang an object on the hook. At the same time, the first nut can be equipped with first screws of various shapes and specifications, and has a wide range of applications.

[0019] 2. In the utility model, by reversing the first screw rod, the first screw rod is made to retreat in the first nut, and then the first nut can be contracted, so that the expansion nut can be taken out from the wall for reuse. At the same time, by setting a few parts, the installation can be very simple. This simple installation method not only improves work efficiency, but also reduces installation costs.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Reference Figure 1-Figure 5 The utility model provides an embodiment: a head pattern implosion type expansion head nut, including a first screw rod 1 and a hook 3. The first screw rod 1 is threadedly connected with a first nut 2. The first nut 2 includes an internal threaded tube 201. The first nut 2 is provided with a vertical groove 202. The end of the first screw rod 1 away from the first nut 2 is fixedly connected with the hook 3. By rotating the first screw rod 1 into the first nut 2 and then making the first nut 2 start to expand, a fastening connection with the wall is achieved. Then, by providing a hook 3 on the first screw rod 1, it is convenient to hang objects on the hook 3. At the same time, the first nut can be equipped with first screw rods of various shapes and specifications, and has a wide range of applications.

[0029] The diameter of the first screw rod 1 is equal to the inner diameter of the internal threaded tube 201, and the length of the first screw rod 1 is twice that of the first nut 2. There are four groups of vertical grooves 202, and the four groups of vertical grooves 202 are evenly distributed on the first nut 2. The first screw rod 1, the first nut 2, and the hook 3 are made of stainless steel. The length of the first screw rod 1 is ten centimeters, the diameter of the first screw rod 1 is one centimeter, the length of the first nut 2 is five centimeters, the first nut 2 is located at the top of the first screw rod 1, and the length of the internal threaded tube 201 is three centimeters. By reversing the first screw rod 1, the first screw rod 1 is retreated in the first nut 2, and then the first nut 2 can be contracted, so that the expansion nut can be removed from the wall for reuse. At the same time, by setting up very few parts, the installation can be very simple. This simple installation method not only improves work efficiency, but also reduces installation costs.

[0030] Working principle: first use a drilling machine to drill a hole, then insert the first screw 1 and the first nut 2 into the hole on the wall, then twist the first screw 1 to make the first screw 1 move forward in the first nut 2, and then make the internal threaded tube 201 on the first nut 2 begin to expand. During the expansion process, the internal threaded tube 201 will form a certain pressure on the inner wall of the hole in the wall. This pressure enables the first nut 2 to be firmly fixed on the wall, thereby achieving an excellent fastening effect. At the same time, the contraction and expansion of the first nut can be suitable for first screws of different sizes. The staff can adjust the first nut and the first screws of different sizes according to needs. Then, the object can be hung on the hook 3, and then the first screw 1 can be reversed to make the first screw 1 move backward in the first nut 2, driving the internal threaded tube 201, and then the expansion nut can be taken out from the hole in the wall for reuse. At the same time, by setting a few parts, the installation can be very simple. This simple installation method not only improves work efficiency, but also reduces installation costs.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
