  Next, the usage method of the attraction string support tool 1 comprised as mentioned above is demonstrated. As shown in FIG. 14, the attracting string support 1 is used by being hooked at the locking portion 4 on a wire 52 that is stretched substantially horizontally above a plant 51 such as a tomato or the like to be attracted. The wire 52 may be hung between struts erected with respect to the ground. In place of the wire 52, a net, a beam, or the like may be used as a support.

  With reference to FIGS. 5-12, the fixing method of the length of the attracting string 40 drawn out from the attracting string support 1 is demonstrated. As shown in FIG. 5, the user grasps the leading end portion 45 of the attracting string 40 wound around the bobbin 41 and feeds it to a predetermined length. It is guided to the front side of the portion 8, that is, to the front side of the protruding portion 46 protruding upward from the holding surface 11 of the left guide wall 13. Then, the user presses and fixes the intermediate portion 47 of the attracting string 40 to the portion 48 positioned below the passage 15 of the main body portion 3 with a finger. In this state, the user passes the distal end portion 45 of the attracting string 40 between the upper edge of the protruding portion 46 and the lower edge of the lever 26.

  Next, from the state shown in FIG. 5, the user displaces the tip 45 to the right while displacing the tip 45 below the upper end of the protruding portion 46. Thereby, the attracting string 40 presses the left side portion 27 of the holding piece 7 to the right, and the holding piece 7 is displaced to the right while resisting the urging force of the connecting piece 6. At this time, since the guide convex portion 25 slides rightward and upward on the guide surface 17, the sandwiching piece 7 is also displaced upward, and as shown in FIGS. 6 and 7, the bottom surface 22 of the sandwiching piece 7 and The holding surface 11 of the base part 8 is separated. As a result, the attracting string 40 enters between the lower surface 22 and the sandwiching surface 11, exceeds the right end of the protruding portion 46, and passes through the passage 15 (on the left and right guide walls 13, 14) as shown in FIGS. Between). In the state shown in FIG. 8, since the attracting string 40 does not press the left side portion 27 of the sandwiching piece 7, the sandwiching piece 7 returns to the state in which the left side portion 27 abuts against the regulation wall 18 by the restoring force of the connecting piece 6. To do. As a result, the attracting string 40 is fitted in the groove 23. The attracting string 40 is restricted from being displaced in the left-right direction by being fitted into the groove 23.

  Next, the user displaces the front end portion 45 upward and forward and places it forward so as to straddle the upper portion 21 of the sandwiching piece 7, and as shown in FIG. It guide | induces so that it may pass between the upper part 21 and the connection piece 6 from back to front. At this time, the leading end 45 is displaced so that the attracting string 40 follows the right side of the string guide wall 28 at the rear side of the holding piece 7.

  Subsequently, the user displaces the distal end portion 45 downward in front of the main body portion 3 and the sandwiching piece 7, and the attracting string 40 moves downward along the front side portion of the sandwiching piece 7 as shown in FIG. 11. It extends and guides the passage 15 so as to extend from above to below. As described above, by pulling the attracting string 40 around the attracting string support 1, the attracting string 40 is arranged so as to rotate once around the holding piece 7 in the vertical direction as shown in FIG. 12. That is, the attracting cord 40 passes between the clamping surface 11 and the lower surface 22 of the clamping piece 7 from the front side to the rear side, and then extends upward along the rear side portion of the clamping piece 7. The upper part 21 is straddled from the rear side to the front side, and extends downward along the front side part of the sandwiching piece 7. Thereby, when an object such as the stem 54 of the plant 51 is connected to the distal end portion 45 of the attracting string 40, the distal end portion 45 of the attracting string 40 is pulled downward, and the holding piece 7 is moved downward accordingly. The attracting string 40 is clamped between the lower surface 22 of the clamping piece 7 and the clamping surface 11. Thereby, the feeding length of the front-end | tip part 45 of the attracting string 40 is fixed.

  When adjusting the feeding length of the leading end portion 45 of the attracting string 40, the user presses the lever 26 to the right as shown in FIG. Thereby, the guide convex part 25 slides on the guide surface 17 upward and to the right, and the clamping piece 7 is displaced upward and to the right. When the holding piece 7 is displaced upward, the lower surface 22 and the holding surface 11 are separated from each other, and the holding of the attracting string 40 is released, so that the feeding length of the distal end portion 45 of the attracting string 40 can be adjusted. When the adjustment of the feeding length is finished, the lever 26 may be stopped from being pressed. Thereby, the holding piece 7 is displaced downward by the weight of the plant 51 connected to the distal end portion 45 of the attracting string 40, and the attracting string 40 is again held by the lower surface 22 and the holding surface 11.

  As shown in FIG. 14, the distal end portion 45 of the attracting string 40 is connected to the stem 54 of the plant 51 via the clamp 53. The distal end portion 45 is coupled to the clamp 53 by adhesion, fastening, or the like, and the clamp 53 sandwiches the stem 54. In other embodiments, the clamp 53 may be omitted, and the tip 45 of the attracting string 40 may be directly connected to the stem 54. As shown in FIGS. 14 (A) and 14 (B), the attracting cord support 1 attracts the stem 54 vertically upward by adjusting the feeding length of the attracting cord 40 as the stem 54 grows. Can do. Further, as shown in FIG. 14C, when the stem 54 is to be attracted to the side, the locking portion 4 is slid relative to the wire 52, and the relative position of the attracting cord support 1 with respect to the stem 54 is changed. What is necessary is just to displace. In addition, the attracting direction of the stem 54 may be changed by supporting the attracting string support 1 by a wire other than the wire 52. At that time, since the locking portion 4 has a simple coupling structure that is only hooked to the wire 52, the wire to be supported can be easily changed.

  The attracting string support tool 1 according to the present embodiment fixes the feeding length of the attracting string 40 using the weight of the plant 51 with a simple configuration in which the attracting string 40 is wound around the holding piece 7. Since the left end portion of the holding piece 7 is a free end, the user can wind the attracting string 40 around the holding piece 7 from the left end side while holding the tip 45 of the drawing string 40. The position of the attracting string 40 in the left-right direction with respect to the base portion 8 is regulated by the passage 15 (left and right guide walls 13, 14), and the position in the left-right direction with respect to the holding piece 7 is regulated by the groove 23 and the string guide wall 28. Further, the operation of winding the attracting string 40 around the holding piece 7 is further facilitated.

  In the attracting string support 1, the clamping surface 11 and the lower surface 22 are tapered surfaces that descend downward as they move backward, so that the mutual contact is good, and the attracting string 40 is held between the clamping surface 11 and the lower surface. 22 can be securely held between the two.

  In addition, the attracting cord support 1 is configured such that the engaging piece 7 is displaced upward by a simple operation of pushing the lever 26 rightward by the engagement between the guide convex portion 25 and the guide surface 17, and the holding surface 11 and the lower surface 22, the holding of the attracting string 40 is released, and the feeding length of the attracting string 40 can be adjusted.

  Moreover, since the attracting string support tool 1 is formed by molding one continuous resin material, it is easy to manufacture and the number of parts can be reduced.

  Although the description of the specific embodiment is finished as described above, the present invention is not limited to the above embodiment and can be widely modified. For example, the downward biasing force of the sandwiching piece 7 by the connecting piece 6 may be increased, and the attracting string 40 may be sandwiched between the lower surface 22 and the sandwiching surface 11 by the biasing force of the connecting piece 6. In this case, even when an object such as the stem 54 is not coupled to the distal end portion 45 of the attracting string 40, the pulling length of the attracting string 40 is fixed. Further, as shown in FIG. 15, the connecting piece 6 may be a metal leaf spring 58. By using such a leaf spring, it is easy to increase the urging force by the connecting piece 6.

  Further, in the embodiment, the sandwiching surface 11 and the lower surface 22 are tapered surfaces that progress downward as they progress backward, but may be tapered surfaces that progress upward as they progress backward.
