いる。[Detailed explanation of the invention] Support rods are provided on both sides of the upper part of the press body, and a guide tube is attached to the support rods.A hand string is passed through the support rods, and as the slide ram descends, the hand string pulls the hand from behind the operator. The rear hand-pull type press safety device, which is designed to remove the operator from the danger zone under the ram, allows the use of a wide floor area around the press machine and, as mentioned above, removes the operator's hands from behind. This method has the advantage of allowing a relatively large range of movement for workers who are tied up with strings, but because the press mold is large in large presses, a forklift or similar device must be used to change the mold. In this case, the guide tube fixed to the front of the press body often becomes an obstacle.

本考案は上記の事情に鑑みなされたもので、手引きひも
案内筒を支持腕に着脱自在に取付け、必要に応じこれを

に取付けである。At the tip of the support rod 2, a holding arm 14 having an angular cross-section is fixed to the lower part at a predetermined angle, and a headed pin 15 and a locking pin 16 are sequentially arranged from above on the upper surface of the holding arm 14. A mounting piece 11' is fixed to the upper part of the mounting piece 11', and a locking hole 17 and an engaging hole 18 consisting of large and small holes are bored in the mounting piece 11'.
The head pin 15 passed through the large diameter hole of the locking hole 1
The guide cylinder 11 is removably attached to the holding arm 14 by being locked in the small diameter hole 7 and the locking pin 16 is locked in the engagement hole 18.

（第３図および第４図）案内筒１１を保持腕１４に取付

きる。Also, since it can be removed very easily by performing the opposite operation to the above, when necessary, such as when replacing the press mold, this guide tube 11 can be removed from the holding arm 14. If the locking hole 17 is engaged with the hanging tool 19 to lock it, it will not get in the way of the work and can help improve work efficiency.

上記ピン１５．１６と係止孔１７、係合孔１８は保持腕
１４と案内筒取付片１１′の何れの側に設けてもよいが
、係止孔１７を保持腕１４に設ける場合には大径と小径
の孔位置を逆にする。The pins 15 and 16, the locking holes 17, and the engaging holes 18 may be provided on either side of the holding arm 14 and the guide cylinder mounting piece 11'; however, when the locking holes 17 are provided on the holding arm 14, Reverse the positions of the large and small diameter holes.

また中径プレス等においては、支持杆２の高さが低くな
るので、保持腕１４もフォークリフト操作の邪魔になる
場合がある。Furthermore, in medium-diameter presses and the like, since the height of the support rod 2 is low, the holding arm 14 may also get in the way of forklift operation.
