[0002]

2. Description of the Related Art As shown in FIG. 4, a wire is first inserted into an insertion member, and the insertion member is inserted into a hollow cylindrical holder. The projection of the holder pushes the wiring upward. In this state, the holder is turned upside down so that the protrusion is directed downward, the holder is pressed against the impeller shaft of the fan, and the wiring is inserted.

[0003]

When the wiring is inserted into the wiring insertion member, it is difficult to insert the wiring because the wiring is small, and both hands must be used. Furthermore, a procedure of inserting the insertion member into the holder has to be taken, which is very time-consuming and inefficient in operation.

The present invention has been made in view of the above facts, and a main object of the present invention is to provide a wiring installation tool which can easily install a wiring on a fan motor, for example.

[0005]

According to the present invention, a cylindrical shape is provided.
The inner diameter of one end is made smaller and the female thread is
And a holder within the holder

A cylindrical member comprising a flange provided at an end of the portion;
Between the insertion member and the cylindrical member in the container.
A coil spring for pressing the insertion member toward one end.
And between the flange member of the cylindrical member and the end face of the holder.
A coil bar interposed so as to be wound around the male screw portion.
And another spring member made of
It is a wiring installation tool .

[0006]

The wiring mounting tool according to the present invention includes a holder.
Hold the hand with one hand and push the insertion member into the wiring.
When attached, a wiring is attached to this free end. This
Hold the end of the insertion member in a predetermined position in the state of
The holder against the contact surface,
The wiring is removed. At this time, insert member and circle
The insertion member advances by the spring member interposed between the column member.
It can move freely. The cylindrical member is screwed into the holder
Because of the tightening position of this cylindrical member,
You can finely adjust the pressing force applied to. In addition, the cylindrical member
The cylindrical part is formed by another spring member between the flange and the holder.
Looseness of the material can be prevented. Furthermore, the enlarged diameter part of the insertion member is
Since it is provided at the end of the pad, the excess
It has a structure that can sufficiently withstand a large pressing force.

DETAILED DESCRIPTION FIG. 1 shows an embodiment of a Wye spear ring mounting tool according to the present invention. In FIG. 1, 1 is an insertion member, 2 is a spring member, 3 is a holder, and 5 is a spring pressure adjusting member as a cylindrical member . The insertion member 1, the holder 3, and the spring pressure adjusting member 5 are formed by cutting a steel material, for example. The insertion member 1 is formed of a stick-shaped rod portion 11 and a cylindrical enlarged diameter portion 12 provided at one end of the rod portion.

The holder 3 has a hollow cylindrical main body 31 and an inner part .
It has a tip inclined portion 32 having a small diameter . A female screw groove is formed on the inner peripheral surface 33 of the main body 31 to a position approximately 20 mm from the upper end. When the insertion member 1 is mounted on the holder 3, the main body 31 is provided with a locking portion 36 with which the enlarged diameter portion 12 comes into contact. A hole 34 is formed. The inner diameter of the through hole 34 is set slightly larger than the inner diameter of the rod portion 11 so that the rod portion 11 of the insertion member 1 can advance and retreat.

A male screw groove is provided on the shaft of the spring pressure adjusting member 5 , and the spring pressure adjusting member 5 has a male screw groove on the cylindrical shaft.
A flange portion is provided at an end of the shaft portion, and is attached to a female screw groove provided on the inner peripheral surface 33 of the holder 3.

Next, a method of mounting a wiring using the wiring mounting tool according to the present invention will be described with reference to FIGS.

FIG. 2 shows a state in which the wiring is inserted into the wiring installation tool. In FIG. 2, an insertion member 1 and a spring member 2 are provided in a holder 3, and a spring pressure adjusting member 5 is screwed to the holder 3. Spring pressure adjusting member 5
By tightening, the spring member 2 interposed between the insertion member 1 and the spring pressure adjusting member 5 is pressed. Since the spring member 2 is pushed downward, the enlarged diameter portion 12 hits the locking portion 36, and the rod portion 11 projects from the holder 3. If it is desired to increase the force applied by the spring 2 to the insertion member 1, the spring pressure adjusting member 5 may be tightened, and if it is desired to be weak, the spring pressure adjusting member 5 may be loosened. Also, between the spring pressure adjusting member 5 and the holder 3,
The spring member 4 is provided to prevent the spring pressure adjusting member 5 from loosening.

On the sponge 10 placed on the case 8, the wiring 7 is placed. When the rod portion 11 protruding from the holder 3 is applied to the wiring 7 toward the wiring 7 and the holder 3 is pressed, the wiring 7 is inserted into the rod portion 11 by the elasticity of the sponge 10.

FIG. 3 shows a state in which the wiring 7 inserted into the wiring mounting tool is mounted in the impeller shaft recess of the fan motor. When the wire ring 7 inserted into the tip portion of the rod portion 11 is applied to the end face of the impeller shaft of the fan motor and the holder 3 is pressed, the rod portion 11 that has protruded due to the contraction of the spring member 2 retreats into the holder 3 and the wire ring 7 Is mounted in the recess of the impeller shaft of the fan motor.

Although the embodiment of the wiring installation tool according to the present invention has been described above, the present invention is not limited to such an embodiment, and various modifications and alterations can be made without departing from the scope of the present invention. It is.

[0015]

Advantages of the Invention The present invention has the above-described structure, and thus has the following effects. The work of inserting the wiring into the wiring installation tool can be performed with one hand, and the fan motor or the like can be held with the other hand, so that efficient work can be performed. Also a cylinder
A spring member for preventing the member from being loosened and an insertion portion
Prolonged use by providing an enlarged diameter section at the end of the material
There is no problem even in.
