Description

  The present invention relates to an invitation fixing tool for plant stems that stops plant stems such as tomatoes and cucumbers on an attracting line hanging from above.

  When cultivating tomatoes, cucumbers, etc., traditionally a splint was set up so that the stem did not fall down due to its own weight or the weight of the fruit, but in recent years it has been troublesome to work and remove it, due to cost savings, in recent years An attracting line is hung from above, and the stem is stopped at the attracting line.

As an invitation fixing tool for stopping a plant stalk on an attracting line, a first sandwiching piece and a second sandwiching piece each having a semicircular stem support part for supporting the stem are connected by a hinge part, and the first sandwiching piece and In the plant stem invitation clip in which a lock portion for holding the both sandwich pieces in a closed state is formed at the tip of the second sandwich piece, an attracting string is formed in a U-shape at the base of the first sandwich piece and the second sandwich piece. There is known a plant stem citation clip characterized by forming an inner string pinching portion and an outer string pinching portion that are tightened in a bent state. (See Patent Document 1)

  In the case of the plant stem citation clip described in Patent Document 1, a flexible lock portion is employed, and the flexible lock portion engages the hooking claw inserted inside the opening with the frame portion of the opening. The clip has an inner diameter that is fixed to a substantially constant size when locked. Therefore, when the diameter of the plant stalk becomes larger than the inner diameter of the clip as it grows, the engagement between the hooking claw and the frame of the opening is released, the hooking claw is pulled out from the opening, the clip is removed, and the plant is removed. The other part of the stem is clipped or left clipped.

  However, when the plant stem grows and the stem diameter increases, it acts to widen the inner diameter of the clip, and the flexible lock part deforms so that the hooking claw further bites into the opening frame part. The engaged state is strengthened, and the flexible lock portion may not be opened even when operated by hand. In such a case, in order to release the locked state of the lock part, a part of the clip is cut with a blade and removed from the plant stem. It was.

  As shown in FIG. 1 to FIG. 6, the plant stem citation fixture 1 includes a first clamping piece 2 and a second clamping piece 3 having arcuate stem support portions 2 a and 3 a that support the stem, respectively, as hinge portions. 4 are connected. A through hole 5a is provided at the base of the first holding piece 2, and a protrusion 5b that is loosely fitted into the through hole 5a is provided at the base of the second holding piece 3.

  The first sandwiching piece 2 has steps on both the upper and lower sides in the thickness direction at a position adjacent to the stem support portion 2a, and a thin piece is formed up to the tip. In this thin piece, an engagement guide 2b is formed adjacent to the stem support portion 2a, and a distal end portion is bent and protrudes outward to form an operation portion 2c. In the engagement guide 2b, a plurality of rack teeth 20 are formed on a surface (inner surface) adjacent to the stem support portion 2a.

  The second sandwiching piece 3 is formed with an engaging groove 3b that is recessed in the center in the thickness direction up to the tip adjacent to the stem support portion 3a. In addition, an operation portion 3c is formed in which a trifurcated branch is formed in front of the engagement groove 3b and a thin piece projects outward from the center. A plurality of rack teeth 30 are formed in the groove of the engagement groove 3b. The engagement guide 2b having a plurality of rack teeth 20 and the engagement groove 3b having a plurality of rack teeth 30 close the first sandwiching piece 2 and the second sandwiching piece 3 and set the size of the inner diameter at that time. The lock part 7 which can set the locked state set and hold | maintained in a several step | level and the 1st clamping piece 2 and the 2nd clamping piece 3 to an open state is formed.

  The rack teeth 20 and 30 are formed in a sawtooth shape in cross section, and the rack teeth 20 of each other are in the positive direction so as to reduce the inner diameters of the first sandwiching piece 2 and the second sandwiching piece 3 in the engagement groove 3b. , 30 can be moved over the engagement guide 2b, and the rack teeth 20, 30 are completely pawled in the opposite directions so as to increase the inner diameter of the first clamping piece 2 and the second clamping piece 3.

When energized, the meshing of the rack teeth 20 and 30 is released.

  Next, with reference to FIGS. 7-9, the usage example of the invitation fixing tool 1 of a plant stem is demonstrated. When cultivating tomatoes, cucumbers, etc., an induction line 90 made of wire etc. is stretched approximately horizontally at a height of about 1.8 to 2 m above the ground, and about twice the height of the induction line. The middle part of the string P made of a synthetic resin having a length of 2 is hung down to the induction line 90 by using a tie 91 for the induction line.

  Then, as shown in FIG. 7, the string P is positioned at the base of the first clamping piece 2 and the second clamping piece 3 of the open-ended invitation fixing fixture 1, and inside the arc-shaped stem support portions 2a and 3a. The plant stem S is placed in In this state, the operation parts 2c and 3c are operated so as to be close to each other, so that the engagement guide 2b of the reference fixture 1 is fitted into the engagement groove 3b, and the through hole 5a at the base of the first clamping piece 2 is inserted. The protrusion 5b at the base of the second sandwiching piece 3 is loosely fitted to the second sandwiching piece 3.

  And it operates so that the operation parts 2c and 3c may approach further, the engagement guide 2b is slid in the engagement groove 3b, and arc-shaped stem support parts 2a and 3a and a part of the engagement guide 2b The inner diameter of the opening 8 formed by the above is reduced, and the inner diameter is such that the first holding piece 2 and the second holding piece 3 are closed at a position where the inner diameter of the invitation fixture 1 matches the size of the plant stem S. The rack teeth 30 and the rack teeth 20 are adjusted to mesh with each other while switching the size of the rack to a plurality of stages. At this time, the protrusion 5b is loosely fitted in the through hole 5a, and the string P is held by the string engaging part 6 surrounded by the hinge part 4 and the protrusion 5b.

  Further, when the plant stem S is brought into a locked state in which the engagement guide 2b and the engagement groove 3b of the lock portion 7 are engaged and the first sandwiching piece 2 and the second sandwiching piece 3 are closed, the plant stem S is supported in an arc shape. It is held in an opening 8 formed by the portions 2a and 3a and a part of the engagement guide 2b. After that, the plant stem S grows and the stem diameter increases, and even if it is energized so as to widen the inner diameter of the invitation fixture 1, the meshing state of the rack teeth 30 and the rack teeth 20 does not change, and the lock The engagement state between the engagement guide 2b and the engagement groove 3b of the portion 7 does not increase.

  Now, when the plant stem S grows as described above and the stem diameter becomes thicker than the inner diameter of the invitation fixture 1, the operation parts 2c and 3c are operated so as to be separated. By this operation, the engagement guide 2b is biased to the outside so as to be removed from the engagement groove 3b, the meshing of the rack teeth 20 and 30 is released, and the engagement guide 2b and the engagement groove 3b of the lock portion 7 are released. Is disengaged. Then, the operation portions 2c and 3c are operated again so that the engagement guide 2b is slid in the engagement groove 3b, and the first position is set so that the inner diameter of the opening 8 matches the size of the plant stem S. The rack teeth 30 and the rack teeth 20 are adjusted and meshed while switching the size of the inner diameter of the reference fixture 1 so as to close the clamping piece 2 and the second clamping piece 3, and the stem is put on the string P stop.

  Thus, when the plant stem S grows and the diameter of the stem becomes thicker than the inside diameter of the clip, the plant stem invitation fixture of the present invention releases the meshing of the rack teeth 30 and the rack teeth 20. Since the lock portion can be changed from the engaged state to the released state simply by adjusting the position where the rack teeth 30 and the rack teeth 20 are engaged, the size of the inner diameter of the opening 8 is adjusted, and the diameter of the plant stem S is adjusted. The stem can be held in response to changes or removed from the plant stem. Therefore, when the plant stem citation fixing tool is removed from the plant stem, it is not necessary to cut a part of it with a blade and can be reused.
