Description

  The present invention relates to a lever-type tool such as a compression pliers, a temporary holding tool used for a lever-type tool, and a method of using a lever-type tool.

  When wiring the wires, there are cases where the wires are connected. At this time, the covering of the electric wires is peeled off to expose the conductive wires, the conductive wires to be connected are arranged, a cylindrical compression connector having a C-shaped or circular cross section is arranged around the conductive wires, and the compression connector is compressed with compression pliers. Connect the wires together.

  As the compression pliers used at this time, there is a so-called lever-type tool that applies a force to the working portion at the tip using a lever principle. An example is the compression pliers 100 shown in FIG.

The compression pliers 100 is an example having a two-stage structure. In other words, the rear ends of the dies 5 and 6 are connected to the front ends of the handles 2 and 3 connected to be swingable about the handle shaft 8 as the first fulcrum by the connecting shafts 9 and 10, respectively. Is done. The dies 5 and 6 can also swing about the shafts 4a and 4b, which are second fulcrums provided on the connecting plate 4 that connects them.
A concave portion 7a and a concave portion 7b are provided in each of the opposing surfaces on the tip side of the dies 5 and 6. FIG. 25A shows a state in which the tips of the dies 5 and 6 are close to each other. At this time, the concave portions 7a and the concave portions 7b form the compression holes 7 having different sizes.

In order to compress the compression connector with the compression pliers 100, first, the rear ends of the handles 2, 3 are separated from each other as shown in FIG. Thereby, the front ends of the handles 2 and 3 and the rear ends of the dies 5 and 6 connected thereto are brought close to each other. Along with this, the tips of the dies 5 and 6 are separated from each other, and the interval between the recess 7a and the recess 7b is widened.
After setting the compression connector C arranged around the conducting wire L to be connected to an appropriate portion of the widened concave portion 7a and concave portion 7b, when applying a force to bring the rear ends of the handles 2 and 3 close to each other, Contrary to the above, the tips of the dies 5 and 6 are close to each other, the compression connector C is compressed, and the conductive wires L are connected (see FIG. 8 of Patent Document 1).

Japanese Patent Laid-Open No. 10-80034

  Since this type of compression pliers 100 has a structure in which a large force is applied to the tips of the dies 5 and 6 by utilizing the principle of the lever, the force applied to the handles 2 and 3 by the operator is reduced. In order to apply the force, it is necessary to shorten the length from the handle shaft 8 to the connecting shafts 9 and 10 and to increase the length from the handle shaft 8 to the rear ends of the handles 2 and 3.

  For this reason, in the compression pliers 100, it is necessary to swing a long handle at a large swing angle, and an operator needs to apply force by holding the rear ends of the handles 2, 3 which are widely opened with one hand.

In the electric wire connecting operation described above, the compression connector C needs to be set in the recess 7a (7b) until the compression of the compression connector C is started. However, since it is assumed that the compression pliers 100 are operated with both hands as described above, it is difficult to set the compression connector C with one hand.
For this reason, in the electric wire connection work, the compression connector C is temporarily compressed using a small pliers once, the lead wire L is temporarily crimped and the compression connector C is temporarily fixed to the lead wire L, and then the compression pliers 100 are attached. In many cases, the lead wires L are connected to each other by carrying out the main compression of the compression connector C.

  However, in such connection work, it is necessary to change the pliers, and there is a possibility that the pliers may be dropped at the time of change, and there is a disadvantage that workability is poor particularly when working alone at a high place. .

  The present invention has been made in view of the above-described problems, and provides a lever-type tool that improves operability and facilitates work, a temporary gripper used for a lever-type tool, and a method of using a lever-type tool. With the goal.

  A first invention for achieving the above-described object is a lever-type tool in which working portions are provided at the distal ends of a pair of handles that are slidably connected around a first fulcrum. The lever-type tool is characterized in that a temporary gripping portion located on the other handle side is provided in the front portion on the fulcrum side.

  With this configuration, in the lever-type tool, the handle can be brought close to each other while holding the temporary holding portion and the handle with one hand, and a force can be applied to the working portion by the lever principle. As a result, when a small force needs to be applied to the working portion at the tip, for example, in the temporary compression of the compression connector, this can be easily performed with one hand, and when a large force is applied, the temporary gripping portion is applied to the handle. Since the operation can be easily carried out, the operability of the lever-type tool can be improved and the operation can be easily performed.

  Further, it is desirable that the temporary gripping portion is provided at a position where the swinging handle does not collide.

  With this configuration, the temporary gripping portion does not hinder the opening and closing of the handle in the lever type tool. In addition, the temporary gripping portion can be provided at a position closer to the other handle, and the operability of the compression pliers can be further improved.

  It is desirable that the temporary gripping portion can be changed by moving the gripping position. Further, it is desirable that the length along the handle length direction of the temporary gripping portion is a length that can be changed by moving the gripping position.

  With this configuration, the lever tool can be operated by moving the gripping position to an appropriate position for the operation. Then, by setting the temporary gripping portion to a length that can be changed by moving the gripping position in the handle length direction, it is possible to adjust the force applied to the working portion by operating the temporary gripping portion. That is, when a small force needs to be applied to the working unit, the operation can be performed by gripping the handle front end side closer to the working unit. When a larger force is applied, the handle rear end side farther from the working unit is grasped. To do the operation.

  Furthermore, it is desirable that the lever-type tool of the first invention further includes a ratchet mechanism for preventing the pair of handles from being separated from each other.

  With such a configuration, the handle is not separated when the one hand holding the temporary gripping part is replaced with the handle or when the temporary gripping part is replaced, so that the workability is further improved.

  In the lever type tool of the first invention, the rear end of the working part and the front end of the handle are connected so as to be swingable, and the working part is swingable about a second fulcrum. It is desirable to have this configuration step by step.

  The lever-type tool having the two-stage structure requires the handle to be largely separated at the time of operation, and is assumed to be operated with both hands. Is very large and is particularly suitable as an object of the present invention.

  Furthermore, the lever-type tool of the first invention is preferably a compression pliers that compresses the object to be compressed in the working unit.

  With this configuration, it is possible to apply the compression pliers provided with the temporary gripping portion to the compression work of the object to be compressed which has a great need for improving workability. By using such compression pliers, after temporarily holding the temporary gripping part with one hand and temporarily compressing the object to be compressed, it is possible to easily carry the main compression from the temporary gripping part to the handle. Therefore, it is particularly effective to provide a temporary gripping part.

  A second invention for achieving the above-mentioned object is a temporary gripping tool used for a lever-type tool in which a working portion is provided at each end of a pair of handles that are swingably connected around a fulcrum. A temporary gripping tool comprising: an arm portion for fixing and a fixing portion that can be fixed to one of the handles.

  If the temporary gripping tool having such a configuration is attached to the lever-type tool, the handle can be brought close to each other while gripping the arm portion and the handle with one hand, and a force can be applied to the working portion based on the lever principle. As a result, when a small force only needs to be applied to the working part, this can be easily performed with one hand, and when a large force is applied, the operation can be easily performed by changing the arm part to the handle. The operability of the lever-type tool is improved and the work can be easily performed.

  It is preferable that the arm portion of the temporary gripping tool is disposed at a position that avoids the swinging of the handle when the fixing portion is fixed to one of the handles.

  With this configuration, when the temporary gripping tool is attached to the lever-type tool, the arm portion does not hinder the opening and closing of the handle. In addition, the arm portion can be provided at a position closer to the other handle, and the operability of the lever-type tool can be further improved.

The temporary gripping tool of the second invention is constituted by a pair of side members having an arm portion and a fixing portion, and these side members are fastened between the arm portion and the fixing portion, thereby being attached to the handle. It is desirable that it can be fixed. Furthermore, when the pair of side members are fastened, it is desirable to arrange a spacing member between these side members.
The temporary gripping tool of the second invention is preferably composed of a pair of side members each having an arm portion and a fixing portion, and the pair of side members are preferably connected at the end portions of the fixing portion.

  With this configuration, it is possible to easily attach the handle to the lever of the lever tool by sandwiching the handle with the fixing portion. Further, when fastening is performed by placing a spacing member between the side members, it is easy to keep the spacing between the arm portions appropriate, and attachment is facilitated even when handling for the first time.

  According to a third aspect of the invention for achieving the above-mentioned object, the second handle of the lever type tool is provided with a working portion at each of the tips of a pair of handles that are swingably connected around a fulcrum. After attaching the temporary gripping tool of the invention, holding the arm part of the temporary gripping tool and the other handle with one hand and applying a small force to bring the handles close to each other and temporarily compressing the object in the working part A method of using a lever-type tool, wherein the pair of handles are brought close together with both hands and compressed.

  By attaching the temporary gripping tool of the second invention to the lever-type tool and using this to perform the compression work as described above, in the conventional method such as the compression work of the compression connector by the lever-type tool when connecting the electric wire, It becomes possible to easily perform a work with poor workability such as the need to change the tool after temporary compression.

  According to the present invention, it is possible to provide a lever-type tool that improves operability and facilitates work, a temporary gripping tool used for the lever-type tool, and a method of using the lever-type tool.

Hereinafter, embodiments of the lever-type tool of the present invention will be described with reference to the drawings.
In addition, although embodiment of this invention gives and demonstrates the example of the compression pliers which compresses to-be-compressed objects, such as a compression connector, as a lever-type tool, it is not restricted to this.

[First Embodiment]
First, a first embodiment of the present invention will be described. FIG. 1 is a view showing a compression pliers 1 which is a lever-type tool of the first embodiment. FIG. 1A is a view showing a side surface of the compression pliers 1, and FIG. 1B is a view of the compression pliers 1 viewed from the rear in a direction indicated by an arrow A in FIG. FIG. 1 shows a state in which the tips of the dies 5 and 6 that are working portions of the compression pliers 1 are brought close to each other.

  The compression pliers 1 are mainly different in that, in addition to the conventional compression pliers 100 described in FIG. 25, the temporary gripping tool 16 is attached from the front part of the handle 3 on the die 5, 6 side to the rear thereof. In addition, the parts already described in FIG. 25 are denoted by the same reference numerals in FIG.

  2 to 8 are views showing the temporary gripping tool 16 in detail. 2 is a perspective view, FIG. 3 is a front view, FIG. 4 is a rear view, FIG. 5 is a plan view, FIG. 6 is a bottom view, FIG. 7 is a right side view, and FIG. In the front view and the plan view, when the temporary gripping tool 16 is attached to the handle 3 of the compression pliers 1, the surfaces located on the tip side (die 5, 6 side) and upper side (handle 2 side) of the compression pliers 1 are shown. The rear view and the bottom view are the opposite, respectively. The right side view corresponds to the plane shown in FIG. 1 (a), and the left side view is the opposite.

  The temporary gripping tool 16 generally has a shape in which two side members 161, 161 formed in a wide U-shape are connected at one end of the U-shape, and a metal having appropriate strength and elasticity is used. It is manufactured by processing and then covering the surface with vinyl or the like.

The side members 161 of the temporary gripping tool 16 each have an arm portion 16a and fixing portions 16b and 16c.
The arm portion 16a is a portion (temporary gripping portion) that performs temporary gripping when operating the compression pliers 1 described later (corresponding to the U-shaped vertical bar portion of the side member 161).
The fixing portions 16 b and 16 c are portions corresponding to the U-shaped end portions of the side members 161, and are portions that fix the temporary gripping tool 16 to the handle 3.
The tips of the fixing portions 16b and 16b (second fixing portions) at one end of the side members 161 and 161 are connected via a crossover portion 164.
At the other end portion of the side members 161 and 161, a screw hole 163 and a hole 167 are provided between the fixing portion 16c (first fixing portion) and the arm portion 16a, respectively, and the screw 162 is connected to one side member 161. The side members 161 can be fastened by being screwed into the screw holes 163 of the other side member 161 and tightened.

As shown in FIGS. 1A and 1B, when the temporary gripping tool 16 is attached to the handle 3 of the compression pliers 1, the handle 3 is interposed between the fixed portions 16 b with the arm portion 16 a facing the handle 2. The handle 3 is disposed between the fixing portions 16c and the screws 162 are tightened into the screw holes 163 to fasten the both side members 161. Accordingly, the temporary gripping tool 16 is fixed to the handle 3 by the fixing portions 16b and 16c.
At this time, the temporary gripping tool 16 is disposed on the front side of the handle 3 (near the handle shaft 8), and when the handles 2 and 3 are closed, the arm portions 16a and 16a are positioned beside the handle 2. Further, the length of the arm portion 16a along the handle length direction is a length that can be changed by moving the gripping position by one hand in the handle length direction, for example, about 150 mm.

  Further, the interval between the arm portions 16a of the both side members 161 is larger than the width of the handle 2, and is provided so as not to collide with the handle 2 where the arm portion 16a swings. In addition, since the arm part 16a is arrange | positioned at the both sides of the handle | steering-wheel 3, what is necessary is just to hold | grip the arm part 16a of the side suitable for an operator's dominant hand at the time of the compression work mentioned later.

  In FIGS. 1A and 1B, reference numeral 20 denotes a connecting portion that connects the handles 2 and 3. The connecting portion 20 includes a bar member 20 a having one end attached to the handle 3, an accommodating portion 20 b that slidably accommodates the other end of the rod member 20 a, and an attaching portion 20 c that attaches the accommodating portion 20 b to the handle 2.

  The other end of the rod 20a accommodated in the accommodating portion 20b has a concave shape and a convex shape (not shown) alternately in the length direction of the rod 20a, and the mounting portion 20c has an irregular shape at the other end. And a latching claw (not shown) biased by a spring or the like, which forms a ratchet mechanism. When the engaging claw is engaged with the irregularities at the other end of the bar 20a, the movement of the bar 20a in the direction of coming out of the accommodating portion 20b is locked, and the separation of the handles 2, 3 is prevented. When the rear ends of the handles 2 and 3 are brought close to each other until the dies 5 and 6 of the compression pliers 1 are completely closed and a predetermined force is applied, the ratchet mechanism is unlocked and the handles 2 and 3 can be separated. .

In the compression pliers 1 of the present embodiment, the arm portion 16a of the temporary gripping tool 16 can be gripped and the compression work can be performed. Is different.
That is, as shown in FIG. 9, first, the rear ends of the handles 2 and 3 are separated to open the dies 5 and 6 of the compression pliers 1. Next, while holding the handle 2 and the arm portion 16a with one hand, the compression connector C disposed around the connecting wire L is set between the concave portions 7a (7b) of the dies 5 and 6 with the other hand. .

  Then, as shown in FIG. 10 (a), the dies 5 and 6 are closed halfway by holding the handle 2 and the arm 16a and holding the compression connector C halfway. Temporarily compress. This temporary compression is performed to such an extent that the conductor L is temporarily fixed by the connector C. Thereby, the conducting wire L is temporarily fixed by the compression connector C.

  Thereafter, the one hand holding the compression connector C and the one hand holding the handle 2 and the arm portion 16a are moved to the rear ends of the handle 2 and the handle 3, respectively, so that both the handles are brought close to each other. A compression force larger than that at the time of temporary compression is applied to the tip of 6 to fully compress the compression connector C, and the conductors L are connected.

  Further, since the compression connector C can be temporarily compressed with a small force, as shown in FIG. 10A, the work can be performed while gripping the distal end side of the arm portion 16a. As shown in FIG. 10 (b), the compression connector C can be temporarily compressed with a larger force by carrying out the operation after changing the hand to the rear end side of the arm portion 16a.

  At the time of the above-described main compression or when the arm portion 16a is changed as described above, the arm portion 16a and the handle 2 are once separated from each other. Is prevented from being separated.

  As described above, according to the first embodiment, the temporary gripping tool 16 having the arm portion 16a is attached to the front portion of the handle 3, and the arm portion 16a is disposed closer to the handle 2 than the rear portion of the handle 3. Since the arm portion 16a and the handle 2 can be gripped, the handles 2, 3 are brought close to each other while holding the arm portion 16a and the handle 2 of the temporary gripping tool 16 with one hand. Forces can be applied to 5 and 6. Thereby, temporary compression of the compression connector C can be performed with one hand. In addition, since the arm 16a can be easily moved to the handle 3 during the main compression, the operability of the compression pliers 1 can be improved and the operation can be easily performed.

Further, when the temporary gripping tool 16 is attached to the handle 3, the arm portion 16a of the temporary gripping tool 16 is in a position avoiding the swinging of the handles 2, 3, so that the opening and closing of the handles 2, 3 is performed by the arm portion 16a. There is no hindrance. In addition, the arm portion 16a can be provided at a position close to the handle 2, and the operability of the compression pliers 1 is further improved.
Furthermore, since the length of the arm portion 16a along the handle length direction is a length that can be changed by moving the gripping position, the arm portion 16a is gripped at an appropriate position for the operation and the compression pliers 1 are operated. And the force applied to the dies 5, 6 can be adjusted. If it is sufficient to apply a small force to the dies 5 and 6 to perform compression work such as temporary compression, the work can be performed by gripping the handle tip side closer to the dies 5 and 6, and compression work can be performed by applying a larger force. When performing the above, the work may be performed by holding the far rear end of the handle with the dies 5 and 6.

  In addition, since the compression pliers 1 have a ratchet mechanism that prevents the handles 2 and 3 from being separated from each other, the one hand is changed from the arm portion 16a to the handle during the main compression, or the holding position of the arm portion 16a is moved. Even in this case, the separation of the handles 2 and 3 is prevented, and workability can be improved.

  Further, when the temporary gripping tool 16 is attached to the handle 3, the handle is sandwiched between the other fixed portions 16 c and 16 c while the handle 162 is sandwiched between the other fixed portions 16 b and 16 b connected by the crossing portion 164, and the screw 162 is attached. The temporary gripping tool 16 can be easily attached to the compression pliers 1.

  The compression pliers 1 according to the first embodiment described above has this configuration in two stages. However, the present invention is not limited to this. For example, a pair of handles having a die at the tip can swing around a fulcrum. The same effect as described above can be obtained by providing the same temporary gripping tool 16 also to the compression pliers having the above-mentioned configuration that is connected to the die and applies force to the die by closing the handle. However, in the case of the compression pliers 1 having this configuration in two stages, it is necessary to open and close the handles 2 and 3 as described above for the purpose of more efficiently applying the force to the dies 5 and 6, and it is assumed that the operation with both hands is performed. Therefore, the provisional gripping tool 16 is provided and the effect of improving the workability by enabling the operation with one hand is very large, and it is particularly suitable for mounting the temporary gripping tool 16.

  Moreover, although this embodiment demonstrated using the example of the compression pliers 1 which performs a compression operation | work using the tip dies 5 and 6 as a working part as an example of a lever-type tool, it is not restricted to this, The above-mentioned die By substituting with for performing various operations, it can be applied to various lever-type tools as they are, and the same effect can be obtained. However, the compression work using the compression pliers performed at the time of connecting the electric wire or the like has a very large need for improving workability, and the above-described effect by providing the temporary gripping tool 16 is particularly effective.

  Furthermore, as shown in FIG. 11, extension handles 18a and 18b may be provided at the rear ends of the handles 2 and 3, respectively. The fixing portion 16c of the temporary gripping tool 16 can be attached from above the extension handle 18b as shown in the drawing. Also in this case, the compression connector can be temporarily compressed and the main compression can be performed by the above procedure, and the same effect can be obtained. Further, since the handles 2 and 3 are extended by the extension handles 18a and 18b and the compression pliers 1 can be operated by applying a force to a portion further away from the handle shaft 8, the main compression can be performed with a smaller force.

  In addition, the temporary gripping tool 16 of the first embodiment has two types of fixing portions, that is, fixing portions 16b and 16b (second fixing portions) that are connected to each other and fixed with the handle 3 interposed therebetween. ) And two types of fixing portions 16c and 16c (first fixing portions) for holding the handle 3 by tightening the screws 162, but the temporary gripping tool of the present invention is used as a fixing portion. Only one of the types may be adopted. The position where the fixing portion is provided may be a position other than the end of the temporary gripping tool.

  Furthermore, it is possible to easily maintain an appropriate interval between the arm portions 16a when the both side members 161 are fastened by using the interval maintaining member. Hereinafter, another example of the temporary gripping tool of the present invention using a spacing member will be described as second to fifth embodiments.

  In addition, in the temporary gripping tool 16 of the first embodiment described above, the arm portions 16a of the both side members 161 come close to each other by tightening the screws 162, so that the arm portions 16a do not hinder the swinging of the handle 2. Although it was necessary to adjust the tightening amount of the screw 162, in the case of the temporary gripping tool 26 of this embodiment, the interval between the arm portions 16 a is determined by the tubular member 165 even when the screw 162 is tightened to the maximum. Kept at a predetermined distance. Therefore, if the length of the cylindrical body 165 is set to an appropriate value such as the width of the handle 2, the arm portion 16a avoids collision with the swinging handle 2 regardless of whether the screw 162 is tightened or not. Since it is arranged in a position, there is an advantage that it is easy to install even when handling for the first time.

FIG. 22 shows a state in which the dies 5 and 6 at the tip of the compression pliers 1a are brought close to each other and closed, as in FIG.

  The compression pliers 1a of the sixth embodiment of the present invention are mainly different in the shape of the handle from the conventional compression pliers 100 described in FIG. Other parts already described in FIG. 25 and the like are denoted by the same reference numerals in FIG.

In the compression pliers 1a, a temporary grip 19 is formed at the front of the handle 3a. A hole 19a is provided in the handle 3a, and the temporary gripping part 19 can be gripped through one hole in the hole 19a. The part of the temporary gripping part 19 where the finger is hung is closer to the handle 2a than the extension line of the part where the finger of the rear part of the handle 3a is hung.
Further, the handle 2a has a concavo-convex shape along the handle length direction, and a concave portion 15 that is concave toward the handle 3a is formed at a position corresponding to the temporary grip portion 19.

  More specifically, as shown in FIGS. 22 (a) and 22 (b), the handle 3a has a substantially U-shaped cross section, and the front portion thereof is formed to receive the swinging handle 2a. That is, the front portion of the handle 3a is composed of a pair of plate-like members arranged to face each other at a predetermined interval in the width direction, and this interval is larger than the width of the handle 2a. A hole 19a is provided in the front portion of the handle 3a, and a temporary gripping portion 19 is formed. Also in the sixth embodiment, the temporary gripping portion 19 is provided at a position avoiding the swinging of the handles 2a and 3a.

  Even with the compression pliers 1a of the present embodiment, it is possible to operate the compression pliers 1a while holding the handle 2a and the temporary gripping part 19 with one hand. At this time, since the concave portion 15 can be gripped and operated on the handle 2a side, the handle 2a and the temporary grip portion 19 can be gripped more easily.

  When the compression connector is compressed using the compression pliers 1a, the same procedure as in the first embodiment can be performed. FIG. 23 is a diagram illustrating temporary compression of the compression connector C by the compression pliers 1a. FIG. 23A is a diagram showing a state in which the compression connector C is set in the concave portion 7a. Thereafter, the compression connector C is temporarily compressed and the main compression is performed in the same procedure as in the first embodiment. FIG. 23B is a diagram illustrating a state in which the compression connector C is temporarily compressed by the compression pliers 1a. Also in this embodiment, the compression operation can be performed by moving the holding position of the temporary holding portion 19 in the handle length direction in accordance with the required compression force at the time of temporary compression.

As described above, the sixth embodiment can provide the same effects as those of the first embodiment. The shape of the temporary gripping portion 19 is not limited to this, and a portion that can be gripped with one hand is sufficient on the handle 2a side of the front portion of the handle 3a. For example, as shown in FIG. 24, the hole 19a is slightly small. It can also be.
