[0010] Hereinafter, cutting process auxiliary tools according to various embodiments of the present invention will be described with reference to the drawings. The description will be made in detail in the order of the configuration of the embodiments, the method of implementation, and modified examples. The following embodiments are merely examples of the present invention, and the present invention is not limited to the following embodiments. Furthermore, the term "substantially" in the application documents is a concept that includes cases where the subsequent shape is chamfered or rounded, and where the elements that make up the shape are deformed or changed in length within a range that does not impede the purpose of the configuration.

[0011] <<Embodiment>> The present invention relates to a processing auxiliary tool X for a tool T for processing a material M, as shown in FIGS. 1 to 3 , and includes a horizontal plate 1 that abuts horizontally against one surface of the material M. The horizontal plate 1 has a clamp receiver 1C that receives a clamp C, and the clamp receiver 1C includes a protruding structure. The clamp receiver 1C has a protrusion, which increases its strength. In an embodiment, the protruding structure includes a concave / convex structure, so that the convex of the concave / convex structure abuts the clamping portion C1 of the clamp C regardless of the size of the clamping portion C1, thereby improving the fixing performance of the clamp C while maintaining the strength of the horizontal plate 1. Here, a convexity refers to a portion that is raised higher than one surface of the horizontal plate 1. However, if the surface on which the convexity is provided includes a recess, it refers to the portion of the recess that is raised higher than the most recessed part of the recess. 3(a) is a plan view of the processing auxiliary tool X, FIG. 3(b) is a rear view of the processing auxiliary tool X, and FIG. 3(c) is a front view of the processing auxiliary tool X.

[0012] Here, the material M may be a plate or block of wood, plastic, or metal, but is preferably a rectangular piece of wood, and in particular, standardized one-by or two-by lumber. The tool T is a tool for cutting the material M, and is particularly assumed to be a circular saw or a jigsaw for cutting wood. On the other hand, depending on the mode of use, it may also be used in combination with an electric screwdriver or an impact driver. The clamp C is a tool for clamping and holding two or more objects, and in this embodiment is a so-called F-type clamp. The clamp C has a clamp body C0 with a handle, a pair of clamping parts C1 for contacting and clamping the material M, and an adjustment part C2 for adjusting the width between the pair of clamping parts C1 to fix the clamp C. Any clamp C may be used as long as it has the clamping parts C1 and the adjustment part C2, and for example, a C-type clamp may be used.

[0013] The processing auxiliary tool X is integrally provided with a horizontal plate 1 that abuts against one surface of the material M, and a vertical plate 2 that extends from the edge of the horizontal plate 1 approximately perpendicular to the horizontal plate 1. The vertical plate 2 abuts against a surface of the material M adjacent to the abutting surface with the horizontal plate 1, and fixes the position of the processing auxiliary tool X at the edge of the material M.

[0014] The horizontal plate 1 has a front surface 1A that faces the top during use and a back surface 1B that comes into contact with the material M during use. The vertical plate 2 extends in the direction of the back surface 1B. Furthermore, at least on the front surface 1A side, a clamp receiver 1C is provided that has an uneven surface due to the protrusions for being clamped by the clamp C.

[0015] The horizontal plate 1 comprises a plate-shaped horizontal plate body 10, a horizontal through-hole 11 provided so as to penetrate the horizontal plate body 10 at a predetermined position, a protruding line 12 which is a rib provided to protrude at a predetermined position on the front surface 1A, and a scale 13 provided along the edge of the horizontal plate body 10. The horizontal plate 1 also comprises a rear protruding line 14 which is a rib provided to protrude at a predetermined position on the back surface 1B, a friction material 15 which rubs against the material M to temporarily fix the position of the horizontal plate 1, and a reinforcing plate 16 provided on the side of the horizontal plate 1 to reinforce the side edge of the horizontal plate 1.

[0016] The vertical plate 2 has a long plate-like vertical plate body 20 connected to the horizontal plate 1 in the longitudinal direction, and a vertical through-hole 21 passing through the vertical plate body 20 at a predetermined position.

[0017] The horizontal plate body 10 is a trapezoidal plate material with a right angle in a plan view. In this embodiment, the horizontal plate 1 has its hypotenuse and height-direction sides extended to form a substantially right-angled isosceles triangle, making it easy to form an imaginary line at a 45-degree angle relative to the edge of the material. Hereinafter, the sides of the horizontal plate body 10 will be referred to as follows: the side on which the vertical plate 2 is attached will be referred to as the lower base side 101; the side perpendicular to the lower base side 101 will be referred to as the height side 102; the side adjacent to the lower base side 101 and forming an acute angle with the lower base side 101 will be referred to as the hypotenuse side 103; and the side parallel to the lower base side 101 and adjacent to the height side 102 and the hypotenuse side 103 will be referred to as the upper base side 104. The horizontal plate body 10 is assumed to be made of plastic, but other materials may also be used.

[0018] The horizontal through-holes 11 penetrate the front surface 1A and the back surface 1B at predetermined positions, allowing the condition of the material M to be checked from the front surface 1A side. The horizontal through-holes 11 have a center hole 111 provided in the center of the horizontal plate 1, a horizontal screw hole 112 which is a small-diameter hole with a diameter large enough to pass a pen tip through, and an attachment hole 113 provided in the horizontal plate 1 near an acute-angle portion.

[0019] The central hole 111 is the largest of the horizontal through holes 11 and is formed in the shape of a right triangle. Each side of the triangle that forms the central hole 111 is parallel to the lower base side 101, the height side 102, and the oblique side 103, and the distances from each side that forms the central hole 111 to the above-mentioned sides of the horizontal plate body 10 are arranged so that they are approximately the same, making it easy to visually understand the state of the material M below the horizontal plate body 10. In addition, a protruding line 12 is arranged along the edge of the central hole 111, which reinforces the central hole 111 and makes it easy to operate the processing auxiliary tool X by placing a hand on the high edge.

[0020] The horizontal screw holes 112 are small holes provided at predetermined intervals in an area surrounded by a height protrusion line 122 and an edge protrusion line 125 (described later). The horizontal screw holes 112 have a minimum inner diameter of approximately 1 mm to 3 mm, but are rounded on the front surface 1A side and tapered from the front surface 1A to the back surface 1B, making it easy to position them accurately from the front surface 1A. The user can use the horizontal screw holes 112 to mark (ink) predetermined positions. It is also possible to drill holes while the processing auxiliary tool X is in contact with the material M, and it can also be fixed with screws.

[0021] The mounting hole 113 is a hole provided between the angle formed by the lower base 101 and the oblique side 103, and has a diameter of about 10 mm. This reduces left-right symmetry, making it difficult to get the mounting direction wrong, and by passing a string or the like through this hole, the processing auxiliary tool X can be hung for storage.

[0022] The protruding lines 12 are a group of linear ribs provided at predetermined positions from the surface 1A, with rounded corners. Preferably, the width is approximately 2 mm to 10 mm, and the protruding height is approximately 1 mm to 15 mm. Each protruding line 12 is approximately equal to the protruding height of the clamp receiver 1C, so that the top surface is flush in side view. This reduces wobbling when placed on a flat surface. In this embodiment, the protruding lines 12 include a lower base protruding line 121, a height protruding line 122, a diagonal side protruding line 123, and an upper base protruding line 124, which are arranged parallel to the lower base edge 101, the height edge 102, the oblique side 103, and the upper base edge 104, respectively. The protruding line 12 further includes an edge protruding line 125 provided along the edge of the horizontal plate body 10, and a circular protruding line 126 disposed on the clamp receiver 1C.

[0023] The lower base protrusion line 121 has one end connected to the edge protrusion line 125 on the oblique side 103 and the other end connected to the midpoint of the height protrusion line 122. The height protrusion line 122 has one end connected to the edge protrusion line 125 on the lower base side 101 and the other end connected to the edge protrusion line 125 on the upper base side 104. The oblique side protrusion line 123 has one end connected to the edge protrusion line 125 on the lower base side 101 and the other end connected to the midpoint of the height protrusion line 122. In addition, the upper base protrusion line 124 has one end connected to the edge protrusion line 125 on the oblique side 103 and the other end connected at the position where the height protrusion line 122 and the oblique side protrusion line 123 intersect. All of these protrusion lines 12 are arranged so that they are approximately equal distances from the parallel edges, improving the strength of the horizontal board 1. Furthermore, some of these protruding lines 12 are positioned so as to surround the edge of the central hole 111, thereby providing height around the central hole 111 and improving strength.

[0024] The edge protrusion line 125 is a part that protrudes along the edge of the horizontal plate body 10, and by making the edge stand upright, it is easier for the user to hook it onto the hand, improving the operability of the processing auxiliary tool X.

[0025] The circular protruding line 126 is a protruding line that protrudes in an arc shape, and is adjacent to the acute angle portion of the center hole 111, and is provided so as to partially include the lower base protruding line 121 and the oblique side protruding line 123. The circular protruding line 126 may be completely circular or may be an elliptical arc. Furthermore, multiple circular protruding lines 126 may be arranged concentrically, which improves the holding performance of the clamp C.

[0026] Here, the clamp receiver 1C is a part that is at least thicker and stronger than the horizontal plate body 10. In the embodiment, the clamp receiver 1C is the part where the lower base protrusion line 121 and the oblique side protrusion line 123 intersect, and by arranging the clamping part C1 above this intersection, the material M and the processing auxiliary tool X can be properly clamped even if the contact surface area of ​​the clamping part C1 is small. The circular protruding line 126 is arranged to surround this intersection point, and when clamping with the large-diameter clamping portion C1, this abuts the clamp C, and when clamping with the small-diameter clamping portion C1, it guides the clamping portion C1 to the intersection point, thereby improving stability. It also adjoins the corner (edge) of the center hole 111, further increasing strength. Furthermore, it makes it easier to determine the installation position.

[0027] The scale 13 is a marking provided at equal intervals to include the height side 102, and in this embodiment, it is a straight groove provided perpendicular to the height side 102, which makes it easy to understand tactilely and increases wear resistance. The scale 13 is provided so that the back surface of the vertical plate 2 is the origin, allowing the distance from the edge of the material M to be measured. In this embodiment, the scale 13 is improved in visibility by alternately arranging small scales that are grooved across the entire width of the height protrusion line 122 and large scales that are grooves of the small scales that extend further into the horizontal plate body 10. In addition, the protrusion lines 12 adjacent to the scale 13 are all perpendicular to the scale 13, further improving visibility.

[0028] In this embodiment, the scale 13 also includes sub-scales 13' that are provided at equal intervals to include the oblique side 103. The sub-scales 13' are grooves that are provided horizontally on the height side 102, and the intervals between the sub-scales 13 are approximately the same as those between the scales 13.

[0029] The rear protruding lines 14 are ribs arranged linearly from the rear surface 1B, and are arranged to have approximately the same shape and size as the protruding lines 12. This prevents the processing auxiliary tool X from sticking to the material M due to atmospheric pressure, and even if there are some protrusions such as nail heads on the plane of the material M, the processing auxiliary tool X can be used horizontally by arranging the protrusions between the rear protruding lines 14 so that they do not interfere.

[0030] The rear protruding line 14 is arranged opposite the protruding line 12 across the horizontal plate body 10. That is, it is arranged on the rear side of the protruding line 12. The rear protruding lines 14 include a rear lower bottom protruding line 141 arranged on the rear side of the lower bottom protruding line 121, a rear height protruding line 142 arranged on the rear side of the height protruding line 122, a rear oblique side protruding line 143 arranged on the rear side of the oblique side protruding line 123, a rear upper bottom protruding line 144 arranged on the rear side of the upper bottom protruding line 124, a rear edge side protruding line 145 arranged on the rear side of the edge side protruding line 125, and a rear circular protruding line 146 arranged on the rear side of the circular protruding line 126. The positions, sizes, and ranges of these lines are arranged in approximately the same manner as the protruding lines 12, except for the rear lower bottom protruding line 141 and the rear upper bottom protruding line 144 described below. The rear protruding line 14 surrounding the central hole 111 is arranged on the rear surface of the protruding line 12 similarly surrounding the central hole 111, so that the thickness of the edge of the central hole 111 is further increased, making it easier to operate by gripping the edge of the central hole 111. In addition, the rear lower bottom protruding line 141, rear oblique side protruding line 143, and rear circular protruding line 146 are provided on the rear of the clamp receiver 1C, and the pressing force received by the clamp receiver 1C is directly transmitted to the material M, thereby improving the holding power of the clamp C. In addition, since multiple protruding lines 12 and rear protruding lines 14 are densely packed near the clamp receiver 1C, the stability and strength of the clamp C are increased when it is attached.

[0031] Here, one end of the back lower bottom protruding line 141 and the back upper bottom protruding line 144 connects to the back oblique side protruding line 143, and the other end passes through the back height protruding line 142 to connect to the back edge side protruding line 145, and the protruding lines are arranged so that they are interrupted on the band where the horizontal screw hole 112 is provided. This prevents interference with the horizontal screw hole 112, increases stability around the hole, makes it easier to attach the screw S perpendicularly to the material M, and further increases the strength of the processing auxiliary tool X.

[0032] The friction material 15 is a member provided on the rear surface 1B, and is made of a material that has a greater static friction force with respect to the material M (especially wood) than at least the horizontal plate main body 10. Examples of such materials include elastic materials such as natural rubber and silicone. The thickness of the friction material 15 is set to be at least slightly (e.g., approximately 0.5 mm to 1.0 mm) thicker than the protruding length of the rear protruding wire 14, ensuring reliable contact with the material M during use and enhancing the holding force of the processing auxiliary tool X. If the friction material 15 is elastic, it is preferable that it deforms when the horizontal plate 1 is placed on it to have the same height as the protruding height of the rear protruding wire 14, which facilitates alignment of the vertical through-holes 21 (described later). In this embodiment, the friction material 15 includes a height friction material 151 adjacent to the height side 102 and a hypotenuse friction material 152 adjacent to the hypotenuse side 103. By providing the friction material 15 adjacent to the edge in this manner, unintended rotation can be effectively suppressed. Meanwhile, the friction material 15 may be provided in other portions of the rear surface 1B.

[0033] The height friction material 151 is a strip-shaped member that is attached to the back surface 1B so as to be surrounded on three sides with gaps by the side of the back edge protruding line 145 that is located at the height side 102, the back lower bottom protruding line 141, and the back upper bottom protruding line 144. The provision of this gap and the fact that one side is open allow the height friction material 151 to be easily deformed.

[0034] The oblique side friction material 152 is a parallelogram strip-shaped member and is attached to the back surface 1B so as to be surrounded on three sides with gaps by the side of the back edge protruding line 145 including the oblique side 103, the back lower bottom protruding line 141, and the back upper bottom protruding line 144. The provision of this gap and the fact that one side is open allow the oblique side friction material 152 to deform. In addition, the oblique side friction material 152 is adjacent to the clamp receiver 1C, improving the holding performance when clamped.

[0035] The reinforcing plate 16 is a member arranged on the side edges of the height side 102 and the oblique side 103 of the horizontal plate main body 10, and is made of, for example, a metal plate that is stronger than the horizontal plate main body 10. The reinforcing plate 16 is arranged slightly outside the edge of the horizontal plate main body 10 in a plan view, thereby preventing direct contact between the tool T and the horizontal plate main body 10 and increasing the durability of the processing auxiliary tool X.

[0036] In this embodiment, the horizontal plate body 10 has grooves or recesses on the back surface 1B side of the scale 13 (sub-scale 13') at the height side 102 and the oblique side 103, and the reinforcing plate 16 is fitted or attached to this portion, thereby being joined as a separate body from the horizontal plate body 10. The reinforcing plate 16 may be made of a magnet so that an iron tool T can be attached to it and slide thereon.

[0037] The vertical plate body 20 is a member that protrudes perpendicularly from the lower base 101 to the surface of the horizontal plate body 10, and is connected by being rounded from the edge protrusion line 125 in the height direction. It is preferable that the protrusion height is approximately the same as the standard length described below.

[0038] The vertical through holes 21 are through holes provided in the vertical plate main body 20, and are arranged at equal intervals with the vertical screw holes 211, which are approximately the same shape as the horizontal screw holes 112 and are provided at approximately the middle position in the direction in which the vertical plate main body 20 protrudes, and the vertical screw half holes 212, which are half holes shaped like the vertical screw holes 211 cut in half and are provided on the edge of the vertical plate main body 20.

[0039] The horizontal screw hole 112, vertical screw hole 211, and half vertical screw hole 212 are provided so that the distance from the edge of the processing support tool X to the center of the hole is a standard length corresponding to the length of the standardized plate material. In the embodiment, the standard length includes half the thickness of the standardized material M (hereinafter referred to as half-thickness standard length) and half the width (hereinafter referred to as half-width standard length). It is preferable that a number corresponding to the standard length is written near each hole.

[0040] For example, the distance from the height edge 102 of the horizontal screw hole 112 is equal to the half-thickness standard length, and the distance from the vertical plate body 20 is equal to the standard length. This makes it easier to mark the position halfway through the thickness of the standard material, improving usability. Furthermore, in the vertical through-hole 21, the distance from the height side 102 in a front view is equal to the half-thickness standard length or half-width standard length, and the distance from the horizontal plate main body 10 is equal to half the half-thickness standard length in the vertical screw hole 211 and equal to the half-thickness standard length in the vertical half screw hole 212, making it easier to mark half the thickness or width of the standard material and improving usability including the ability to temporarily fix the processing auxiliary tool X. Furthermore, the vertical screw hole 211 can also accommodate half-size standards.

[0041] Furthermore, with the above configuration, it is easy to draw a horizontal line parallel to the edge of the material M along the upper base side 104 and a straight line along the lower base protrusion line 121 at the center hole 111.

[0042] How to use A method for carrying out the present invention will be described in detail below with reference to Figures 4 to 6. The present invention is carried out by a user who cuts material M. The method for carrying out the present invention is an example, and the method for carrying out the present invention is not limited to this, and the order of the steps may be reversed.

[0043] First, as shown in Figure 4, the user clamps the clamp C as a holding step. That is, the user abuts the back surface 1B of the horizontal plate 1 against the flat surface of the material M, and then abuts the vertical plate 2 against the surface adjacent to this flat surface. In this state, the user aligns the clamp receiver 1C with the clamping part C1 of the clamp C, and narrows the width of the clamping part C1 with the adjustment part C2, thereby fixing and holding the processing auxiliary tool X and the material M.

[0044] Next, as shown in Figure 5, the user cuts the material M using tool T as a cutting process. That is, the user can cut the material in a straight line by aligning the height side 102 and the edge of tool T, and then starting and sliding tool T. Note that the user can also cut material M along a 45-degree line by aligning tool T with oblique side 103.

[0045] As shown in Figure 6, the user may mark the horizontal screw holes 112 and the vertical through-holes 21 by inserting a marking tool such as a pen into the holes. Here, since the horizontal screw holes 112 and the vertical through-holes 21 are formed to the half-thickness standard length and half-width standard length, the marking can be performed appropriately on the standardized central axis of the lumber. The user then performs drilling and nailing according to the marking.

[0046] The user may temporarily fasten the tool with a screw as a holding step. That is, the user may drill the horizontal screw hole 112 or the vertical through hole 21 and screw in the screw S to fix the processing auxiliary tool X and the material M. This allows the processing auxiliary tool X to be fixed without using a clamp C, which does not interfere with the work. The horizontal screw hole 112 or the vertical through hole 21 may be used to drill a pilot hole with a drill bit of standard length. The user may also perform both holding with the screw S and holding with the clamp C.

[0047] <<Example of change>> In the modified example shown in FIG. 7(a), the clamp receiver 1C is configured so that the top surface of the protruding structure is flat, making it less likely to rattle when clamped by the clamp C. The height of the top surface is the same as the height of the protruding wire 12, and the top surface of the clamp receiver 1C is configured so that it is parallel to the front surface 1A, improving holding performance and strength. In addition, the clamp receiver 1C is configured so that it has a notched shape so as not to overlap with the center hole 111, thereby maintaining the truss around the center hole 111 and increasing strength. As in the embodiment, the back surface 1B may be provided with a rear circular protruding wire 146, but a protrusion with a flat top surface may also be provided, as on the front surface 1A side.

[0048] In the modified example shown in Figure 7(b), the clamp receiver 1C is provided so that the top surface of the protruding structure is flat. Explanation of the same configuration as in Figure 7(a) will be omitted. In this modified example, the clamp receiver 1C is provided so as to be disk-shaped, and a portion of it is arranged to cover the corner of the triangular center hole 111, making it easier for the clamping part C1 to be supported by the entire clamp receiver 1C. In this modified example, the portion covering the center hole 111 of the clamp receiver 1C is connected to the rear circular protrusion 146 or protrusion provided on the rear surface 1B to increase strength. Alternatively, the disk-shaped clamp receiver 1C may be provided so as to be placed on the surface of the horizontal plate 1.

[0049] In the modified example shown in Figure 7, where the top surface of the protruding structure is flat, a circular protruding line 126 may be further provided to surround the edge of the top surface of the protruding structure of the clamp receiver 1C. This circular protruding line 126 improves usability by guiding the clamp C inside the protruding structure. In the modified example of Figure 7(a), the circular protruding line 126 is provided in a position excluding the cutout portion, which makes the above-mentioned effect even more effective.

[0050] As shown in the modified example in Figure 8, two or more clamp holders 1C may be provided, and by holding the clamp holder 1C at two or more positions, rotation during installation may be made less likely. In this modified example, in addition to the clamp holder 1C, a second clamp holder 1C2 and a third clamp holder 1C3 with a concave-convex structure are provided. Each of these clamp holders includes an arc-shaped circular protruding line 126 that is provided adjacent to the intersection of the protruding lines 12 or / and the corner of the center hole 111. The circular protruding line 126 is provided away from the height side 102 so as to avoid the horizontal screw hole 112, and its center is located near the intersection of the protruding lines 12.

[0051] In the second clamp receiver 1C2, as in the modified example shown in Figure 7(b), a portion of the circular protruding line 126 is arranged to cover the corner of the triangular central hole 111, and the inside of the circular protruding line 126 is made solid, making it easier to receive the clamping portion C1. Furthermore, the third clamp receiver 1C3 is provided with a plurality of concentric circular protruding lines 126, thereby increasing its strength while allowing it to accommodate clamping parts C1 of various diameters.

[0052] Depending on the shape of the material M, the processing auxiliary tool X can also clamp the material M with the clamp C inserted into the center hole 111, and since the two clamp receivers 1C are on the same straight line, the holding performance is improved. The clamp receivers 1C may be provided on the vertical plate 2, or may be designed to clamp the vertical plate 2 while the material is rotated.

[0053] Furthermore, the horizontal plate 1 has a plurality of linearly protruding protruding wires 12, which are provided on the surface on which the clamp receiver 1C is provided, thereby reinforcing the horizontal plate 1. Furthermore, the connection between the clamp receiver 1C and the protruding wires 12 can further increase the connection strength between the clamp receiver 1C and the horizontal plate 1. In particular, the protruding wires 12 intersect at the clamp receiver 1C, so that it can be easily clamped even by a small-diameter clamping portion C1.

[0054] In addition, the horizontal plate 1 is provided with a plurality of rear protruding lines 14 that protrude linearly on the surface on the side where the protruding lines 12 do not protrude, and the rear protruding lines 14 are arranged just on the back side of the protruding lines 12, thereby increasing the strength of the horizontal plate 1. Furthermore, by providing a plurality of rear protruding lines 14 and providing friction material 15 between the rear protruding lines 14 that is thicker than the protruding height of the rear protruding lines 14, the temporary fixing performance by pressing the processing auxiliary tool X against the material M can be further improved.

[0055] In addition, the horizontal plate 1 has a central hole 111 in the center, and the protruding line 12 is arranged along the edge of the central hole 111, thereby reinforcing the area around the central hole 111 and increasing the height of the edge to improve operability.

[0056] Furthermore, the horizontal plate 1 includes a circular protruding line 126 that protrudes from the horizontal plate 1 so as to surround the center of the clamp receiver 1C, thereby increasing the contact area and enabling proper holding even with a large diameter clamping portion C1.

[0057] In addition, vertical plates 2 extend perpendicular to the horizontal plate 1 at the edge of the horizontal plate 1, and vertical through holes 21 are provided at predetermined intervals in the vertical plates 2, making it possible to hold and mark the material M with screws S even in the thickness direction. Furthermore, by including vertical screw half holes 212 located at the edge of the vertical plates 2, it is possible to drill holes and perform other operations at positions that comply with standards while minimizing the width of the vertical plate 2. Furthermore, by providing horizontal through holes 11 in the horizontal plate 1 as well, it is possible to hold and mark the material M with screws S even in the width direction.

[0058] Furthermore, the method of using the processing auxiliary tool X includes a holding step of placing the clamping portion C1 of the clamp C in the clamp receiver 1C, which makes it easier to determine the position of the processing auxiliary tool X. On the other hand, the holding step may be performed by fastening the horizontal through-hole 11 or the vertical through-hole 21 with a screw, or a combination of these methods.
