Further, the rotating spring hook pivotally supports the left and right free ends of the series of bent steel wires to the left and right sides of the base end side of the tool engaging member, and a guide portion opposed to the left and right sides of the tool storage portion. Since it has a locking portion that is locked to the tip of the tool engaging member, it is possible to control the rolling of the tools by the guide portion, and to operate the rolling control position and the release position of the spring hook with one touch. .

  The left and right free ends of the rotating spring hook pivotally supported by the tool engaging member are pivotally supported by shifting the rotational center position in the axial direction of the tool engaging member, so that the spring hook rotated upward is at both ends. It is stably held at the open dead center position due to interference caused by the difference in pivot position.

  By providing a holding hole for detachably attaching spare parts to the plate of the support frame, spare safety bolts can be quickly procured.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.
FIG. 1 shows an example of an agricultural machine in which the present invention is used. A soil cultivator 3 and a deep cultivator are provided for each of a plurality of middle bone beams 2 arranged in parallel on a horizontally long bar 1 pulled by a tractor (not shown). The cultivator 5 which attached attachments, such as 4, is shown.
In the embodiment of FIG. 1, the tool hanger 6 of the present invention is fixed to the side surface of the main body 2 of the working machine.

  The tool hanger 6 is rotatably supported by a support frame 7 fixed to the main body of the agricultural machine, a tool engaging member 8 projecting in the upper lateral direction of the support frame 7, and a base of the tool engaging member 8. An attached rotating spring hook 9 is provided.

The lower part of the support frame 7 is a plate extending upward by fixing the lower part of the support frame 7 to the central beam 2 of the agricultural machine, and the tool engaging member 8 is fixed to the upper part thereof in the lateral direction (preferably horizontal). Has been.
The tool engaging member 8 is a supporting member having a strength necessary for engaging and holding related tools 10 such as a wrench and a spanner necessary for adjusting the work machine, and is fixed to the support frame 7. It has the tool accommodating part 11 of predetermined length toward the front end side of a base.

The rotating spring hook 9 is made of a series of metal or other linear material having predetermined rigidity, strength, bending workability, etc., and the left and right free ends 12a, 12b formed by bending a series of steel wires are attached to the tool. A guide pivotably mounted on the left and right base end pivot portions 13a and 13b provided on the base end side of the member 8 and extending downward from the base end pivot portions 13a and 13b and crossing below the tool engaging member 8 The tool engaging member 8 is further extended to the upper end side of the tool engaging member 8 via the portion 14, and a bent coupling portion at the end thereof is formed in the inverted V-shaped engaging portion 15 that is locked to the distal end of the tool engaging member 8. It consists of a series of members.
Thus, the rotating spring hook 9 is reversible from the position where the inverted V-shaped engaging portion 15 is locked to the distal end of the tool engaging member 8 to the upper open position with the proximal end pivot portions 13a and 13b as fulcrums. It has a structure that can be rotated.

  As shown in FIG. 4, it is preferable that the rotating spring hook 9 pivotally supports the left and right free ends 12a and 12b on the base end pivot portions 13a and 13b whose positions are slightly shifted along the axis of the tool engaging member 8. . As a result, when the rotating spring hook 9 is rotated to the upper open position as shown in FIG. 4, the rotation of the left and right free ends 12a and 12b is interfered by the difference of the rotating fulcrum position, and the rotating spring hook 9 is It is stably held at the rotational dead center position.
