Have been done. Conventionally, such work has been carried out, for example,
Special tools and the like as described in JP 160794
Using, the joint from painting the liquid to facilitate sliding in Sakomiashi place where crowded fitted to a rigid pipe, plug operation
Isn't it a time-consuming and user-friendly job?
Was.

[0003]

The present invention is to provide a view of the above, the present invention is convenient to carry a small, aims to also be used to develop a simple fitting tool.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to meet the above-mentioned object, and comprises a tool body through a reciprocating rod provided with a linear reversing saw tooth, and a handle portion pivotally supported by the body. A lever-shaped handle protruding to the outside, a retraction control lever pivotally supported by the lever-shaped handle to engage with a retreating saw tooth and protruding an engagement release handle outward, and a fixed pipe bite fixed to the main body A half piece, a movable pipe biting half which comes into contact with and separates from a release side face of the half piece and attaches a handle piece to a side face of the main body at the time of joining ;
A lock that presses the handle piece that is supported and attached to the side
It is characterized by comprising a clever and a holder for supporting a pipe joint with an insertion leg provided on the advance / retreat rod corresponding to the pipe to be bitten by the movable pipe bite half.

[0005]

According to the present invention, the end of the pipe P having a radius slightly larger than the radius of the fixed pipe is fitted into the fixed pipe gripping half 17 of the tool body 1 by slightly projecting the end thereof, and the handle piece 21 is operated.
The movable pipe gripping half piece 20 is replaced with the fixed pipe gripping half piece.
17 and tighten pipe A so that handle piece 2
1 is brought into contact with the side surface of the tool body 1. In this state,
Turn the lock lever 22 counterclockwise as shown in FIGS.
So that the handle piece 21 does not move with the elasticity of the pipe P
Apply a lock. Then, after fitting the fitting T to the holder 24 of the reciprocating rod 7 to make the insertion leg Ta correspond to the center of the pipe P, the operation of pushing the lever-shaped handle 10 in the direction of the arrow in FIG.
When the operation is repeated, the control lever 14 swings interlockingly about the axis and intermittently meshes with the retreating saw tooth 8 each time the lever-shaped handle 10 is pressed, and the joint T is moved in the direction of the arrow in FIG.
It is not forcibly plug Murrell the end of Sakomiashi Ta pipes P as shown in FIG. Further, in the lever-type handle 10 from 4 state to the original state of FIG. 1, the disengagement operation handle 1
6 is lifted as shown by the chain line in FIG.
Out of engagement with the retreating saw tooth 8.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a side view, FIG. 2 is a partially cutaway side view, FIG. 3 is a front view, and FIG. FIG.

[0007] Reference numeral 1 denotes a tool main body, which is composed of two symmetrical main body cases 2 and 2 facing each other as shown in FIG.
To form a passage 4 through which the reciprocating rod 7 can be freely moved horizontally, and a lever-shaped handle 10 is provided below the passage 4.
A missing 5 which projects the handle portion, reverse control lever 1 4
Of the handle 6 projecting from the disengagement operation handle 16 .

[0008] 7 is a reciprocating rod through forward and backward freely to form the L-shaped in the passage 4 of the main body case 1, a portion passing through the passage 4 and an inverted convex cross-section, receding straight to the lower convex surface A row of saw blades 8 is formed . In addition, a pin 9 for preventing the rod from dropping out of the passage 4 is inserted into the rear end of the advancing / retracting rod 7 . Reference numeral 10 denotes a lever-shaped handle supported by a shaft 11 inside the tool main body 1. The handle portion 12, which is wound around the shaft 11 and one end of which is fixed to the main body 1, is fixed to the other end of the spring 13, is cut off. 5 protrudes rearward and outward.

Further, a retreat control lever 14 which engages the retreating saw tooth 8 as shown in FIG. 2 with the weight of the disengagement operation handle 16 at the tip of the lever type handle 10 as shown in FIG. The front part of the shaft 15 is moved to the disengagement operation handle 16 described above.
And On the upper surface of the main body 1, a fixed pipe biting half 1
The L-shaped seat 18 provided with 7 is attached with a screw 19. (Because the outer diameter of the pipe P is not constant, several kinds of L-shaped seats 18 are prepared so that they can be replaced each time the diameter is different.)
7, the handle piece 21 at the time of joining in FIG.
To attach the movable pipe to the side of the body 1
0 is fixed to the rising portion of the L-shaped seat 18 with a screw 19. (Normally, it is set with the L-shaped seat 18.)

[0010] When the handle pieces 21 of the side movable pipe掴着for halves 20 of the main body case 1 is in contact as in FIG. 3 the solid line on the side surface of the main body 1 without continuing pressing by hand, strong
A lock lever 22 that is pressed down is supported by a shaft 23.

The fixed and movable pipe biting halves 17,
The joint T with the insertion leg Ta is fixed to the rising portion of the reciprocating rod 7 corresponding to the center of the pipe P to be bitten by 20.
A holder 24 for supporting is exchangeably mounted with a set screw 25.

Regarding the operation of the portable insertion tool of the present embodiment ,
State. To the fixed pipe holding half 17 of the tool body 1 ,
The end of the hard synthetic resin pipe P such as polyethylene of slightly thicker radius than the radius of the semi piece inlaid by slightly protruding, Ha
Operate the handle 21 and move the movable pipe gripping half 20 forward.
Move the pipe A close to the fixed pipe gripping half 17 side
Tighten the handle piece 21 to contact the side of the tool body 1
Let In this state, as shown in FIGS.
22 is turned counterclockwise so that the handle piece 21
Lock to prevent movement with elasticity. Next, the forward / backward rod 7
The holder 24 is fitted to fitting T Ru made to correspond to Sakomiashi Ta at the center of the pipe P. And the lever type handle 10
Is pressed several times against the spring 13, the control lever 14
Swings interlockingly about the shaft, and intermittently meshes with the retreating saw tooth 8 each time the lever-shaped handle 10 is pressed, and the joint T
Since the moving in the arrow direction in FIG. 1, <br/> as shown in Figure 4 Sakomiashi Ta forcibly inserting Murrell the end of the pipe P.

[0013]

The portable fitting tool of the present invention can quickly and easily perform the work of inserting the fitting insertion leg into a pipe end of a hard pipe made of a synthetic resin such as polyethylene or the like.
It has the effect of being suitable for carrying .
