Conventionally, as a retracting tool, the retracting tool is equipped with a holding part that expands in diameter by screwing in a threaded member, and the holding part is used to expand the diameter inside the pipe at the pulling end of the pipe to be inserted, such as a flexible pipe. By holding the tube to be inserted, and
There is a system in which the tube to be inserted is inserted into the sheath tube by pulling a retracting tool that holds the tube to be inserted using a rigging such as a wire that has been inserted into the sheath tube in advance (Utility Model Publication No. 59-105674) (see publication).

However, in the conventional type described above, when a cord such as a wire is strongly pulled, the holding part whose diameter has been expanded by screwing in the threaded member in the previous holding operation separates from the pipe to be inserted (flexible pipe) and pulls in. There was a problem that the tool easily came off the tube to be inserted.

向上する点にある。 The purpose of the present invention is to solve the above-mentioned problems through rational improvements, and at the same time, to improve the operability of the retractor.

通りである。
The characteristic structure of the flexible pipe retractor according to the present invention is that a holding part is provided for holding the flexible pipe by expanding the diameter inside the pipe at the pulling end of the flexible pipe, and a diameter expanding operation part is engaged with the holding part. A sliding member is provided at one end and a connecting portion for the retracting rope at the other end, and the engagement structure between the holding portion and the diameter expanding operation portion is connected to the retracting rope of the sliding member. The sliding member has a cam engagement structure in which a pulling operation force toward the tool connection side is converted into a diameter expansion operation force of the diameter expansion operation section against the holding section, and the sliding member has an end portion on the connection section equipment side. It is constructed so that it can be connected to and separated from the part on the equipment side of the diameter expansion operation part, and its functions and effects are as follows.

管に引込み挿通する。
In other words, by pulling the sliding member toward the retracting rigging connection side with the holding part located inside the tension end of the flexible pipe, the pulling force is transferred to the holding part and the diameter expansion operation part. The action of the cam engagement structure with the flexible pipe converts it into a diameter expansion operation force for the holding part to expand the diameter of the holding part, and the diameter expansion brings the holding part into pressure contact with the inner periphery of the flexible pipe.
Alternatively, the flexible pipe is held by locking or the like, and in this held state, the flexible pipe is pulled and inserted into the sheath pipe by pulling the rigging connected to the connecting portion.
また、その引込み挿通過程においては、索具の
引張り操作力（すなわち、摺動部材の引込み用索

力）として作用する。 In addition, during the retraction insertion process, the pulling force of the rigging (that is, the pulling force of the sliding member toward the connecting side of the retracting rigging) is applied to the cam engagement structure between the holding part and the diameter expansion operating part. As a result, it always acts as a diameter expansion operation force for the holding part (in other words, a force that reliably and firmly holds the holding part to expand the diameter of the flexible tube).

適当工具を用いて摺動部材を強く押し込むことが
必要なときに特に有用である。 Furthermore, when removing the retracting tool from the flexible pipe after completing the retraction of the flexible pipe, the sliding member is pushed into the diameter expanding operation part to allow the diameter of the holding part to contract. To release the holding part from expanding the diameter, at this time, the end part of the sliding member on the side equipped with the connecting part, which can be freely connected and separated, to the part equipped with the diameter expanding operation part, is attached to the side equipped with the diameter expanding operation part. By separating it from the section, the part of the sliding member on the side that is equipped with the diameter expansion operation part can be easily pushed into the diameter expansion operation part side without the rigging or connecting parts getting in the way. The ease of operation is due to the fact that, as mentioned above, during the pulling and insertion process, the pulling force of the rigging always acts as a diameter expansion operation force on the holding part, so the grip between the holding part and the diameter expansion operation part becomes tight. This is particularly useful when it is necessary to forcefully press the sliding member using a suitable tool such as a hammer or the like.

に至つた。
As a result of the above, during the drawing and insertion process, the pulling operation force of the rigging always acts as a diameter expansion operation force on the holding part (i.e., a force that reliably and firmly holds the holding part against the flexible pipe by expanding its diameter). This effectively suppresses and prevents the conventional problem that when ropes such as wires are pulled strongly, the holding part in an enlarged diameter state separates from the flexible pipe and the retracting tool tends to come off. It has now been possible to smoothly draw and insert the flexible tube into the tube.

た。 In addition, the cam engagement structure between the holding part and the diameter expansion operation part ensures that the holding part holds the diameter of the flexible tube in the flexible tube during the drawing and insertion process reliably and firmly as described above, but when the drawing is completed, By separating the end portion of the sliding member on the side equipped with the connecting part, the retractor can be easily removed from the flexible pipe without the rigging or the connecting part getting in the way, making it extremely easy to operate. It has now been possible to create a flexible pipe retractor.
