Description

  The present invention relates to a connection tool, for example, a connection tool suitable for exchanging, replacing, or combining various tool handles.

  Conventionally, for example, a bit lock structure has been used to replace the tip of a screwdriver or drill.

  In addition, as an example using a bit lock structure, for example, a stopper body attached to a bit body in which a bit portion is formed at a tip attached to an automatic driver, the stopper body allows rotation of the bit body. In addition, the screw body is configured to be detachably attached to the bit body in a state in which the bit body cannot be moved in the axial direction, and a screwing surface of a screwing member into which a screw, a screw, or the like is screwed into the stopper body The stopper surface is formed on a surface perpendicular to the axis of the stopper body and is provided so as to be able to project and retract. When the stopper body is attached to the bit body, the bit portion is the stopper. There is one that slightly protrudes from the surface (for example, see Patent Document 1).

JP-A-8-267366

However, the conventional bit lock structure has only been used for limited purposes, mainly for exchanging the tip of a drill or screwdriver.
In general, at a site where tools such as tools are used, depending on the place of work, if the hand cannot be reached or if the handle is a little longer, it is necessary to work in a place where the hand can reach.
In such a case, with conventional tools such as a screwdriver and a drill, the handle cannot be exchanged, so that there is a problem that it is very difficult to use or it takes time to move for work. For example, when painting paint on a high heel, it is easy to paint where you can reach it, but you need to bring a stepladder etc. where you can not reach it and apply it on the stepladder. There was a problem that it was very troublesome and time-consuming.

Although it is possible to carry two long and short tools depending on the work place, there is a problem that the number of tools to carry increases.
Also, if the handle of the tool becomes long, the handle may get in the way and get caught around, and the storage efficiency will be reduced, so there is a problem that many tools cannot be carried at once. .
In addition, for example, there is a case where it is necessary to clean the waste generated when the hole is opened after the operation of making a hole in a tree or the like is finished. In such a case, conventionally, it was necessary to change the hand holding the drill to a scissors or a brush, which was extremely inefficient.

The present invention has been made in view of the above-mentioned problems. When using any tool, the length of the tool can be changed according to the place and work, and the tip tool can be exchanged with one touch. Therefore, it is possible to improve the working efficiency and to provide a connection tool for enhancing the storage efficiency when carrying tools and the like.
In addition, a connection tool that can be easily attached to and detached from these tools is provided.

  A connector according to one aspect of the present invention includes a bit body in which a groove is formed at a tip portion, a sleeve in which a hollow hole including a large diameter portion and a small diameter portion is formed, and an axial direction in the hollow hole of the sleeve. An anvil in which a lock hole into which the bit body is inserted is formed, a spring which is arranged in the hollow hole of the sleeve and urges the anvil in an axial direction, and is arranged in the hollow hole of the sleeve; When the bit body is inserted, the bit body is engaged with the groove of the bit body by being positioned at the small diameter portion of the hollow hole, and the anvil is moved against the urging force of the spring. It is a joining tool comprising a lock body composed of a steel ball retracted in a large diameter portion of a hollow hole, wherein a joining member is provided at a lower end portion of the bit body and the lock body.

The joining member may be a wood screw.
The joining member may be a screw and a nut.

  The joining member may be formed in a flat plate shape.

  The joint part of the lock body may be attached to the handle, and the joint part of the bit body may be attached to a temporary part of the tool.

The pattern may be a pattern having a different length.
A plurality of the lock bodies may be attached to the handle by the joining member.

The joints may be attached in different directions.
The bit body may be attached to the joint member so as to be rotatable.

  A screw may be attached to the rotating portion between the bit body and the joining member, and the rotation of the bit body may be restricted by the screw.

Hereinafter, an example of an embodiment according to the present invention will be described with reference to the drawings.
FIG. 1 shows an example of an embodiment of the present invention.
The connecting tool shown in FIG. 1 includes a lock body 110 and a bit body 120.
The lock body 110 includes a lock member 1 and a wood screw portion 111 formed at the lower end portion of the lock member 1. The lock member 1 has a configuration similar to that of the conventional lock member 1, and is configured such that the bit 2 can be attached and detached with one touch. The wood screw portion 111 is configured as a wood screw that is directly screwed into the wood to be fixed, and the lock body 110 can be secured to the wood by screwing the wood screw portion 111 into the wood. ing.
The bit body 120 includes a pillar portion 2 and a wood screw portion 122 formed at the lower end portion of the pillar portion 2. This column portion 2 has the same configuration as that of the conventional column portion, is formed in a hexagonal column shape, and an annular groove 2a is formed in an intermediate portion in the height direction.
Further, the wood screw portion 122 constitutes a wood screw that is fixed by screwing into the wood, and the bit body 120 can be fixed to the wood by screwing the wood screw portion 122 into the wood. It has become.

The structure of the lock member 1 will be described.
As shown in FIG. 2, in the bit portion 3, an anvil 30 in which an insertion hole 31 for holding the column portion 2 is formed, a steel ball 32, and a sleeve 33 slidably attached to the outer periphery of the anvil 30, One end is constituted by a compression spring 35 which is locked to a retaining ring 34 and biases the sleeve 33.

The anvil 30 is formed with an insertion hole 31 having a hexagonal hole corresponding to the hexagonal axis of the column part 2, and the column part 2 is inserted into the insertion hole 31.
A holding hole is formed in the insertion hole 31 so as to be opposed to each other in the radial direction, and a steel ball 32 is disposed in the holding hole. The steel ball 32 is disposed in the holding hole of the anvil 30 and is held in the insertion hole 31 by a sleeve 33 disposed on the outer periphery of the anvil 30 so that a part of the steel ball 32 is retained. It is comprised so that it may engage in the annular groove 2a of the pillar part 2. FIG.
In addition, the diameter of the holding hole of the anvil 30 is appropriately set so that the steel ball 32 does not fall into the insertion hole 31.
A spring 40 is disposed between the upper bottom portion of the insertion hole 31 and the column portion 2. When the column portion 2 is inserted into the insertion hole 31 by the spring 40, the column portion 2 is urged downward by the spring 40. Thereby, the annular groove 11a is urged downward, and by restricting the movement of the steel ball 32, it is possible to prevent play and prevent the handle portion 2 from wobbling with respect to the saddle plate portion 1. . In addition, whether this spring 40 is provided is arbitrary.

The sleeve 33 is slidably attached to the outer periphery of the anvil 30 and is always biased downward by a compression spring 35 interposed between the sleeve 33 and the retaining ring 34.
Thereby, the steel ball 32 is held at a position protruding from the insertion hole 31 by the inner periphery of the sleeve 33.
An annular groove 33a is formed in the inner peripheral portion of the lower end of the sleeve 33. When the sleeve 33 is slid upward, the steel ball 32 is retracted into the groove 33a, and the steel ball 32 and the pillar portion are retreated. The engagement with the two annular grooves 2a is released.

Next, a method for attaching and detaching the lock member 1 will be described.
First, when attaching the column part 2, the anvil 30 is operated upward against the urging force of the compression spring 35. Thus, the steel ball 32 is retracted into the holding hole and the groove 33a, and the column portion 2 is fitted into the insertion hole 31 against the urging force of the spring 40 in this state.
When the operation of the anvil 30 is released in this state, the sleeve 33 slides downward by the urging force of the compression spring 35. Due to the movement of the sleeve 33, the steel ball 32 is pushed out of the groove 33 a of the sleeve 33 into the insertion hole 31, and one end portion of the steel ball 32 is fitted into the annular groove 2 a of the column portion 2 to be prevented from coming off. The state is maintained by the urging force.
Further, in this state, the column portion 2 is in a state where the upper end portion thereof is urged downward by the spring 40.

Further, when removing the column portion 2 from the lock member 1, the sleeve 33 is operated to the upper side of the anvil 30 against the urging force of the compression spring 35 so that the steel ball 12 is fitted in the groove 33 a of the sleeve 33. .
As a result, the steel ball 32 can be retracted into the holding hole and the groove 33a, and the steel ball 32 is detached from the annular groove 2a, so that the column portion 2 can be extracted from the insertion hole 31 of the anvil 30.

An example of using the connector thus configured will be described.
FIG. 3 shows an example in which the bit body 120 is attached to the wooden handle portion of the paint roller 130. In this example, the paint roller 130 includes a wooden handle 131, a roller 133, and a support bar 132 that supports the roller 133. The bit body 120 is fixed to the bottom of the handle 131 by screwing in a wood screw 122.
Further, the lock body 110 is fixed to the front end portion of the rod-shaped handle 140 separate from the paint roller 130 by screwing a wood screw 111 of the lock body 110.

In this state, for example, when it is desired to lengthen the handle of the paint roller 130, the bit body 120 is inserted into the lock body 110 of the handle 14.
Thereby, since the lock body 110 locks and holds the bit body 120, the handle of the paint roller 130 can be lengthened.
Further, when it is no longer necessary, when carrying it, the bit body 120 can be unlocked, the handle 140 can be removed and carried.

In the above-described example, the example of adding the handle has been described, but the handle may be exchanged. In this case, the bit body 120 may be attached to the tip of the support bar 132.
Thereby, the shape, thickness, etc. of the pattern which an operator likes can be selected.

Similarly, as shown in FIG.
The bit body 120 is attached by screwing a wood screw 122 into the bottom of the handle of the graft rod 150. Accordingly, the graft rod 150 and the handle 131 can be coupled by inserting the column part 2 of the bit body 120 into the bit body 120 of the separate handle 131.
Thereby, the same effect as the above-mentioned example can be produced.

Although the above-mentioned embodiment demonstrated the example which attaches the bit body 120 to a rod-shaped handle, it is an example which attached the bit body to the flat handle.
As shown in FIG. 5, the bit body 200 is formed of a column portion 2 and a flat mounting plate portion 210 formed at the lower end of the column portion 2.
In the mounting plate portion 210, screw fixing holes 211 and 212 are formed at the upper and lower end portions of the mounting plate portion 210, respectively.

A method of using the bit body 200 will be described.
As shown in FIG. 6, the bit body 200 is screwed into the holes 211 and 212 through wood screws while the bit body 200 is positioned on the flat handle 301 of the skin 300.
Thereby, the bit body 200 is attached to the handle 301 of the skin 300, and thus the aforementioned handle 140 can be attached and detached.

Further, as shown in FIG. 7, the bit body 200 may be attached to the flat handle 401 of the brush 400.
Similarly, in this case, the bit body 200 is positioned on the handle 401 of the brush 400 and screwed into the holes 211 and 212 through wood screws.
As a result, the bit body 200 is attached to the handle 401 of the brush 400, whereby the handle 140 can be attached and detached.

Next, another embodiment will be described.
The connector shown in FIG. 8 includes a lock body 510 and a bit body 520.
In this example, in place of the wood screw described above, screw portions 511 and 521 are provided in the lock body 510 and the bit body 520, respectively, and are attached by nuts 530 or wing nuts 540.

In this way, in the example shown in FIG. 8, the lock body 510 and the bit body 520 can be easily attached by passing the screws 511 and 521 through the holes of the handle and the like and stopping them with the nut 530 or the wing nut 540. be able to.
Thereby, the same effect as the above-mentioned embodiment can be produced.

Another embodiment will be described with reference to FIG.

Moreover, when carrying, etc., the handle 141 and the main body can be separated and stored compactly.

  Further, as shown in FIG. 15, the length of the handle can be extended by attaching the bit body 2 to the tip portions of the handles 606 and 605.

As for the shape of the handle, as shown in FIG. 15, the lock body 1 may be attached to a part in the width direction of the round bar-like handle 701.
As a result, since the shape of the handle can be freely deformed, for example, when working with the handle 141, it was necessary to repeat a movement in a certain direction, but by attaching a handle 701 having a different shape to the handle 141, The movement of the operator's hands and arms can be made different.
Thereby, even if an operator does not repeat a fixed movement, the same operation | work can be continued with another way of moving a hand or an arm by attaching the handle | pattern 141.

In addition, even when a person with a physical disability or an injury has occurred and a certain movement cannot be performed, a pattern shape corresponding to the movement can be selected.
For example, in the case of a normal round bar-shaped handle when moving left and right, it is necessary to move the arm largely to the left and right, but the movement can be changed by changing the shape of the handle.

Another embodiment will be described with reference to FIG.
In FIG. 16, the handle 720 has lock bodies 1a, 1b, 1c attached to the axial front end portion, rear end portion, and intermediate portion, respectively.
Thereby, another tool can be attached to each lock body.
For example, the lock body 1a is a hammer, the lock body 1b is a brush, and the lock body 1c is a mirror. As a result, it is possible to inspect the place where the nail is struck with a mirror and the nail is struck with a mirror after the work part is first cleaned with a brush.
In this way, a plurality of tools can be shared by one handle 720, eliminating the trouble of bringing back the tools.
Moreover, since the lock body 1 is attached toward different directions, it is less likely to obstruct each operation.

As another embodiment, FIG. 17 shows an example of an attachment for the bit body 2.
In the example shown in FIG. 17, (a) is an example in which the bit body 2 is attached to the fixture 800 with a thumbscrew.
