[0022] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without inventive work.

[0023] To simplify the drawings, only the parts relevant to the utility model are schematically shown in each figure; they do not represent the actual structure of the product. Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically shown or labeled. In this document, "one" not only means "only one" but also "more than one," and "several" includes "two" and "more than two."

[0024] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0025] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0026] Refer to the instruction manual Figure 1-5, a quick-installed expansion bolt, including an expansion bolt body 1, one end of the expansion bolt body 1 is fixedly connected to an extrusion block 2, the external thread sleeve of the expansion bolt body 1 is provided with an embedded block 3, one end of the embedded block 3 is fixedly connected to an expansion fixing sleeve block 4, one end of the expansion fixing sleeve block 4 is in contact with the extrusion block 2, a rotation groove 5 is opened inside the expansion bolt body 1, a rotating block 6 is rotatably connected inside the rotating groove 5, an auxiliary handle 7 is fixedly connected to the outer wall of the rotating block 6, the auxiliary handle 7 passes through the expansion bolt body 1 and is fixedly connected to a first gear rod 9, the outer wall of the first gear rod 9 is provided with a gear strip 11, and a second gear rod 10 is provided inside the gear strip 11, one end of the expansion bolt body 1 is fixedly connected to an auxiliary inner cover 8, a rotating cover 12 is provided at one end of the expansion bolt body 1, and the inner wall of the rotating cover 12 is fixed to the second gear rod 10 Connection setting; when the expansion bolt body 1 completes the operation of embedding into the wall, the knob operation of the rotating cover 12 can be performed immediately, and then the second gear rod 10 inside the rotating cover 12 will be driven to rotate, and under the action of the gear leather 11, the first gear rod 9 will also be driven to rotate. At this time, the first gear rod 9 will drive the rotating block 6 to rotate, and then the auxiliary handle 7 will rotate with the rotating block 6 as the center of the circle. At this time, the auxiliary handle 7 will be screwed out of the outer wall of the expansion bolt body 1. At this time, the operator can hold the auxiliary handle 7 tightly and then rotate the expansion bolt body 1. Due to the large friction force, the extrusion block 2 can move normally, thereby squeezing the expansion and fixing sleeve block 4, causing the expansion and fixing sleeve block 4 to deform and expand normally, thereby ensuring the normal installation process of the expansion bolt body 1.

[0027] Then, two groups of rotating grooves 5 are provided inside the expansion bolt body 1 , and the two groups of rotating blocks 6 and the auxiliary handles 7 are provided in a symmetrical structure; the two groups of auxiliary handles 7 can increase the fulcrum when the user holds it, thereby improving the rotation efficiency.

[0028] Then, the auxiliary handle 7 is set in an oval shape, and the outer wall of the auxiliary handle 7 is provided with anti-slip grooves; through this structure, the auxiliary handle 7 will not cause discomfort to the user during operation due to the sharp corners, and the effect of the anti-slip grooves also increases the friction between the auxiliary handle 7 and the user when holding it, further improving the rotation efficiency of the equipment.

[0029] Next, the first gear rod 9 is arranged in a meshing manner on one side of the gear leather strip 11, and another first gear rod 9 is meshed on the other side of the gear leather strip 11; through this arrangement, the rotation of the first gear rod 9 can drive the other first gear rod 9 to rotate together, so that the two sets of auxiliary handles 7 can cooperate to achieve the desired operating effect.

[0030] At this time, the second gear rod 10 is arranged in the middle of the gear strip 11 in an engaged manner, one end of the second gear rod 10 is fixedly connected to the inner wall of the rotating cover 12, and the other end of the second gear rod 10 is rotatably connected to one end of the expansion bolt body 1; the second gear rod 10 can be driven by the rotating cover 12, and then the second gear rod 10 can mesh with the gear strip 11 to produce a transmission effect, so that the two groups of first gear rods 9 can rotate together.

[0031] Next, one end of the expansion bolt body 1 is fixedly connected to the auxiliary inner cover 8, and the inner wall of the rotating cover 12 is fitted onto the outer wall of the auxiliary inner cover 8; through this structure, the rotating cover 12 rotates more stably, thereby enabling the rotating cover 12 to rotate stably.

[0032] Secondly, a rubber gasket is provided on the outer wall of the rotary cover 12 ; this structure increases friction when the rotary cover 12 is rotated, so that the operator will not slip when rotating the rotary cover 12 .

[0033] Finally, the outer wall of the embedded block 3 is provided with a quartz sand coating, which forms a rough texture on its surface. This structure increases the friction between the embedded block 3 and the embedded groove in the wall to a certain extent, thereby improving the stability of fixing the expansion bolt body 1 in the wall.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
