[0025] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0026] The following embodiments can be understood as explaining a partial structure of the present invention individually, or as explaining a larger structure of the present invention through a combination of multiple embodiments.

[0027] A portable folding tobacco seedling spacer, such as Figures 1-8 As shown, a positioning ruler structure is formed by connecting multiple straight ruler segments 1. Several grooving components 3 are slidably connected to the positioning ruler structure. The grooving components 3 are fixedly connected to the positioning ruler structure through positioning components and are distributed at equal intervals. A handle 2 is provided at the center of the top of the positioning ruler structure along the longitudinal direction. Adjacent straight ruler segments 1 are connected by plug-in components. The plug-in components include a first rod 10 and a second rod 12 that are hinged to each other.

[0028] like Figure 1 , 2, 7, the handle 2 is provided with a U-shaped clamping rod 9, the size of the U-shaped clamping rod 9 satisfies: to transversely constrain the structure of the folding of the multiple straight ruler segments 1, avoid the straight ruler segments 1 to scatter, the top of the U-shaped clamping rod 9 is provided with a sliding sleeve (not marked in the figure), the sliding sleeve is sleeved on the handle 2, the handle 2 above the sliding sleeve is provided with external threads and is screwed with a rotating sleeve 7, the handle 2 between the rotating sleeve 7 and the sliding sleeve 8 is provided with a compression spring 8.

[0029] As shown in Figure 1 , 2 , 8, the size of the straight ruler segment 1 is the same, the upper surface of each straight ruler segment 1 is provided with a scale line, and the upper surface of the positioning ruler structure is spliced into a complete scale ruler 18 by the scale lines. According to the scale mark, the spacing of each chisel assembly 3 can be quickly adjusted, and each spacing can be accurately controlled to be consistent.

[0030] As shown in Figure 1 , 8 , the straight ruler segment 1 is provided with a strip-shaped sliding groove 17 penetrating the upper and lower ends along the length direction, the positioning assembly includes a screw rod 4 penetrating the strip-shaped sliding groove 17 along the longitudinal direction and being in sliding connection with the strip-shaped sliding groove 17, the screw rod 4 is screwed with a locking nut 5 on the rod body above the straight ruler segment 1, and the lower end of the screw rod 4 is fixedly connected with the top of the chisel assembly 3.

[0031] As shown in Figure 1 , 2 , the chisel assembly 3 is an inverted conical structure, the top end of the chisel assembly 3 is fixedly connected with the bottom end of the screw rod 4, and the locking nut 5 is used to fix the chisel assembly 3 at the set position of the straight ruler segment 1, that is, the top of the chisel assembly is pressed tightly with the bottom of the straight ruler segment by tightening the locking nut 5.

[0032] As shown in Figures 1-7 , one end of the straight ruler segment 1 is provided with an axial cross-shaped sliding groove, the horizontal groove 6 of the cross-shaped sliding groove is located on one side close to the end of the straight ruler segment 1 and penetrates the two side walls and the end of the straight ruler segment 1, and forms an opening 601 for the outward rotation of the rod 10, the vertical groove 15 of the cross-shaped sliding groove is formed as a limiting structure 11 towards the groove wall of one side of the end of the straight ruler segment 1, and the vertical groove of the cross-shaped sliding groove extends away from the horizontal groove along the axial direction of the straight ruler segment.

[0033] As shown in Figures 1-7As shown, cylindrical sliders 16 are respectively provided at the upper and lower ends of one side of the outer surface of the first rod 10. The cylindrical sliders 16 are slidably and rotatably connected to the vertical groove 15. The end of the first rod 10 away from the cylindrical slider 16 is hinged to the end of the second rod 12 through a vertically set hinge shaft (not shown in the figure). The other end of the second rod 12 is fixedly connected to the end of the adjacent ruler segment 1. When the first rod 10 is fully inserted into the cross-shaped groove, the hinge shaft and the end of the second rod 12 near the hinge shaft are restricted to the vertical groove. At this time, the first rod 10 and the second rod 12 cannot rotate relative to each other (around the hinge shaft) due to the restriction (at the same time, the notch also restricts the second rod from moving up and down, that is, restricts the second rod from moving axially along the hinge shaft). The opposite ends of the adjacent ruler segments 1 are tightly fitted. As an improvement, a damping rubber layer should be provided on the inner surface of the cross-shaped groove or the outer surface of rod one and rod two to prevent the adjacent ruler segments from slipping off during use.

[0034] The working principle of this new type:

[0035] like Figures 1-9 As shown, during use, insert rod one into the bottom of the cross-shaped groove of the adjacent ruler segment. At this time, because the hinge shaft and one end of rod two are limited by the vertical groove, rod one and rod two cannot rotate relative to each other. Rod one and rod two are tightly connected to the cross-shaped groove, so the adjacent ruler segments will not slip off, and the opposite ends of the adjacent ruler segments are tightly connected, forming a complete positioning ruler structure. Then, according to the cultivation design requirements, adjust the position of each hole-cutting component and fix it with the locking nut. Finally, hold the handle and cut holes in the cultivation soil through each hole-cutting component to form planting holes with consistent spacing.

[0036] When folding is required after use, first pull outwards along the adjacent ruler segments, causing the cylindrical slider 16 to slide to one side of the notch and be stopped by the limiting structure 11. Figure 7 As shown, rotating the ruler segments causes rod one and rod two to rotate around the hinge axis, with a portion of the rod extending beyond the notch. Adjacent ruler segments then press against each other, completing the folding action. Figure 8 As shown, after each ruler segment is folded relative to the other, rotate the rotating sleeve and let the two arms of the U-shaped clamp straddle the outside of the folded ruler segments. Due to the extension of the compression spring, the two arms of the U-shaped clamp hold the structure of the folded ruler segments 1, preventing the ruler segments 1 from spreading out. Then, by lifting the handle, the spacer can be taken away.
