Detailed Implementation

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In addition, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those of ordinary skill in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of this application.

[0027] Reference Figure 1-8 As shown, an auxiliary lever includes a main substrate 101; at least two through regions 102 disposed on the main substrate 101; and a lever block 103 disposed on the main substrate 101 and extending in the direction of the through regions 102.

[0028] Specifically, such as Figure 1-2 As shown, side plates 104 are provided on both sides of the main substrate 101, forming a general "U" shape. The side plates 104 on both sides form a track groove 105 that runs through the main substrate 101 in the longitudinal direction. The bottom surface of the track groove 105 is lower than the inner wall surface of the main substrate 101, and the length of the side plate 104 is much greater than the depth of the track groove 105.

[0029] The through region 102 is disposed on the panel of the main substrate 101. The through region 102 also penetrates the pressure plate. The through region 102 includes a first through region 1021 and a second through region 1022. At the same time, it is necessary to ensure that the area of ​​the first through region 1021 is greater than the area of ​​the second through region 1022.

[0030] Specifically, the first through area 1021 is a circle-like shape, and the second area is a rectangle-like shape. The diameter of the circle-like shape is the same as the width of the rectangle-like shape, and the rectangle-like shape is a rectangle.

[0031] The first through region 1021 and the second through region 1022 are not connected. A tapered cylinder 1031 is provided on the pressing block 103 in the extending direction of the second through region 1022, so that the second region is in an extended state and the second through region 1022 decreases in depth.

[0032] In actual installation, the first through-area 1021 is used for inspection, and the second through-area 1022 is used for installation. Therefore, the auxiliary lever 1 does not need to be tightened when inspecting. The position needs to be fixed only after the position is determined. Therefore, a structure is needed to solve this problem.

[0033] At least one protrusion 1051 is provided on one of the two side walls of the track groove 105, and a track groove extension edge 1052 is provided on both sides of the inner wall surface of the main substrate 101. The position of the protrusion 1051 does not exceed the end of the track groove extension edge 1052. Specifically, there is one protrusion 1051, which is located in the middle of the side wall on one side of the track groove extension edge 1052.

[0034] The auxiliary lever 1 is made of plastic and has certain deformation characteristics.

[0035] The auxiliary lever 1 is applied on a track 2, such as Figure 3-7 As shown, the track 2 is composed of a main body 21 and track edges 211 disposed on both sides of the main body 21. At the same time, the track edges 211 on both sides and the main body 21 can form an open cavity 212. When the auxiliary lever 1 is installed on the track 2, it slides in the length direction of the open cavity 212.

[0036] On the two sides of the track edge 211, there are oppositely arranged hair strip inserts 213. Each hair strip insert 213 is composed of two inverted and symmetrical L-shaped blocks, which form a T-shaped inner cavity. Inside the hair strip insert 213, there are oppositely arranged hair strips 22. Each hair strip 22 is composed of inserts and hair bundles arranged on the inserts. The inserts and hair bundles form a T-shape. The thickness of the track edge 211 is the same as the width of the track groove 105. The two sides of the track edge 211 are inserted into the track groove 105.

[0037] The distance from the end of the track edge 211 to the bristle insert 213 is at least equal to the depth of the track groove 105. To ensure that the bristle 22 can be pried open, such as... Figure 8As shown, when the track edge 211 is fully embedded in the track groove 105, the distance a from the push block 103 to the open cavity 212 is greater than the distance b from the insertion port of the hairpin insert 213 to the opening of the open cavity 212. Furthermore, the distance a can be equal to the distance b from the middle of the hairpin 22 to the open cavity 212. Moreover, the surface of the conical cylinder 1031 is close to the bottom of the open cavity 212. This arrangement is for the convenience of screw installation.

[0038] The working process of this utility model is as follows: When using the auxiliary lever 1, first align the track groove 105 on the auxiliary lever 1 with the track edge 211 on the track 2. First, locate the fastening hole located on the main body 21 and inside the cover of the hairline 22 through the first through area 1021. At this time, if... Figure 4 , 6 As shown, the track edge 211 does not pass through the protrusion 1051. At this time, the auxiliary lever 1 is pre-installed on the track 2 and is positioned on the track edge 211 by the friction between the two. The lever 103 squeezes the bristle 22, and the bristle 22 is pushed to both sides. The fastening hole is selected by sliding the auxiliary lever 1 up and down. After finding it, the second through area 1022 is aligned with the fastening hole. Then, the auxiliary lever 1 is pressed again towards the track 2. Figure 5 , 7 As shown, since the auxiliary lever 1 is made of plastic, through plastic deformation, the auxiliary lever 1 can be fastened to the side of the track 211. The screw is placed inside the conical cylinder 1031, and the screwdriver bit is inserted into the conical cylinder 1031 and sucks the tail of the screw, so that the screw is screwed into the fastening hole.
