Furthermore, cylindrical caps 16, 16 made of resin are fitted into the handles 3, 4 near the pivot shaft 2, and slides around the pivot shaft 2 of the cylindrical caps 16, 16. Projections 17,... Protruding outward are provided as stop prevention means.

As shown in FIG. 2, the edge 4 of the handle 4
A first ratchet 8 and a second ratchet 9 are engraved on the c and 4c as ratchets 7, respectively. The first ratchet 8 and the second ratchet 9 are connected to the pivot shaft 2 (hole).
4b), they are arc-shaped with the same radius around the center, are formed at the same pitch, and are configured to face each other in the axial direction of the pivot shaft 2.

Further, as shown in FIG. 3, the first ratchet 8 and the second ratchet 9 have different phases in the direction around the pivot shaft 2, and in this embodiment, the second ratchet 9 is It is in a state shifted from the ratchet 8 by a half pitch.

As shown in FIG. 2, reference numeral 10 denotes a rotating body which is rotatably connected to the handle 3 and is formed by press-forming a band plate, and has a substantially U-shaped cross section. And
The space between the opposing parts (opposing parts) 10a, 10a formed by press-forming in a substantially U-shape is substantially the same as the distance between the opposing parts 4a, 4a of the handle 4.

Further, a first claw 12 and a second claw 13 are formed at end edges 10b, 10b of the rotating body 10 as protruding claws 11 capable of engaging with the ratchet 7, respectively. A first claw 12 with the first ratchet 8 and a second claw
13 can be engaged with the second ratchet 9.

Further, one end of a coil spring 14 is fixed as an elastic body to a connecting portion 10c connecting the opposed portions 10a, 10a of the rotating body 10, and the other end of the coil spring 14 is Locking hole 1 as a holding portion formed in the facing portion 3a of
Locked to 5. Therefore, the rotating body 10 is urged by the coil spring 14 in the direction in which the pawl 11 is engaged with the ratchet 7, and the pawl 11 is always engaged with the ratchet 7.

When the pawl 11 engages with the ratchet 7,
The shape of the claw 11 and the tooth surface 7a is set so that the claw 11 and the tooth surface 7a of the ratchet 7 come into surface contact with each other. In this embodiment, as shown in FIG. The tooth surface 7a has the same radius as the claw 11 and is formed in a concave arc.

As shown in FIG. 1, the pressing elements 6, 6
It is configured to open and close in cooperation with the opening and closing operation of 3, 4
The crimp terminals and the like inserted between the teeth 18, 18 formed at the opposing positions of the pressers 6, 6 can be pressed and crimped.

An arc-shaped convex portion 21 is formed on the one pressing element 6, and an arc-shaped concave section 22 is formed on the other pressing element 6, into which the convex element 21 can be engaged. The pressers 6, 6 open and close around this portion.

The manual crimping tool according to the present embodiment has the above-described configuration. Hereinafter, the manner of engagement between the ratchet 7 and the claw 11 will be described with reference to FIG. First, in a plan view shown in FIG. 3, the first claw 12 of the claw 11 abuts on the outer (X direction side) tooth surface of the first ratchet 8a, and the second claw 13 of the claw 11 is connected to the second ratchet 9a. The ratchet 7 and the claw 11 are engaged with each other by contacting the inner (opposite side in the X direction) tooth surface, and the grips 3 and 4 are maintained at a constant opening and closing angle.

If the handles 3 and 4 are closed in this state, the handle 4 rotates in the direction P about the pivot shaft 2 and the first claw 12 is moved to the outer teeth of the first ratchet 8a. Surface of the rotating body 10 against the urging force of the coil spring 14
Rotate in the direction.

Thereafter, when the first claw 12 is separated from the outer tooth surface of the first ratchet 8a, the rotating body 10 rotates in the R direction by the urging force of the coil spring 14, and the first claw 12 is moved to the first ratchet.
At the same time that the second pawl 13 comes into contact with the inner tooth surface of the second ratchet 9b, the second claw 13 comes into contact with the outer tooth surface of the second ratchet 9b. That is, the pawl 11 is moved relative to the ratchet 7 by the first ratchet 8a and the second ratchet 8a.
Ratchet moving at half the pitch of 9b
7 and the handles 3, 4 are maintained at an opening angle smaller than the initial opening angle.

The engagement between the ratchet 7 and the claw 11 according to the present embodiment is as described above. However, in the manual crimping tool according to the present embodiment, the ratchet 7 is not a separate body as in the related art. The protrusions 21 formed integrally with the handle 6, not the conventional pins, should be formed integrally with the handle 4. By locking the coil spring 14 directly on the handle 3 instead of locking the coil spring 14 on the support pin fixed to the handle 3 as in the related art, it is possible to eliminate components such as pins, ratchets, and support pins. Therefore, the assembly work and the adjustment work can be simplified by reducing the number of parts,
In addition, there is an advantage that it can be manufactured at low cost.

The ratchet 7 has a hole 4b (a pivot shaft).
Since the teeth of the ratchet 7 are machined on the basis of 2), the dimensional accuracy of the ratchet 7 with respect to the rotation center (pivot shaft 2) of the handle 4 can be ensured. There is an advantage that the assembly can be performed inexpensively and quickly without performing a centering adjustment operation of the ratchet with respect to the pivot shaft.

Further, in the manual crimping tool,
Ratchet 7 is replaced by first ratchet 8 and second ratchet 9
And the phases of the pivot shafts 2 of the first ratchet 8 and the second ratchet 9 in the direction around the axis are shifted from each other, so that the pitch of the first ratchet 8 and the second ratchet 9 can be adjusted. A ratchet having a half pitch can be formed, and there is an advantage that the opening / closing angle of the handles 3, 4 can be changed at a smaller angle.

Moreover, since the pitches of the first ratchet 8 and the second ratchet 9 themselves are not made fine, the processing becomes complicated and the processing cost is deteriorated, and the tooth strength is reduced and the life of the ratchet mechanism is reduced. Is advantageously prevented from decreasing.

The claw 11 has a convex arc shape and a tooth surface.
7a has the same radius as the claw 11 and is formed in a concave arc.
When the hook 11 engages with the ratchet 7, the pawl 11 and the tooth surface 7a of the ratchet 7 are configured to abut against each other.
4 forcibly open, the outer edge of the claw 11 does not come into line contact with the tooth surface 7a, so that the scratch on the tooth surface 7a caused by the outer edge of the nail 11 This has the advantage that the life of the ratchet 7 can be suitably prevented from being shortened.

Further, since the rotating body 10 is formed by press-forming a strip, the rotating body 10 is cheaper and simpler than those conventionally formed by a sintering method or a lost wax method. It has the advantage that it can be formed.

Further, in the state where the handles 3 and 4 are combined, the ratchet 7, the claw 11 and the coil spring 14 of the handle 4 are arranged between the facing portions 3a and 3a of the handle 3, so that
Since these cannot be recognized from the outside, the hand-operated crimping tool has the advantage that it does not give a rough impression and has an excellent appearance.

Further, conventionally, as shown in FIG.
Since the ratchet mechanism 45 is interposed between the handle 41 and the cylindrical cap 56 for the purpose of preventing slippage, it is not possible to insert the handle to the vicinity of the pivot shaft 40 of the handle 41. When opened, there is a problem in that the grips 41, 41 near the pivot shaft 40 become slippery, which makes it difficult to hold the portions securely and makes it difficult to close the handles 41, 41. Since the outer edges of the handles 41, 41 near the shaft 40 are bulging in the direction away from each other, when the handles 41, 41 are opened to the maximum angle, the outer edges of the handles 41, 41 near the pivot shaft 40 further increase in angle. Therefore, there is a problem that slipperiness is promoted. However, in the manual crimping tool according to the present embodiment, the outer edges 3d and 4d of the grips 3 and 4 near the pivot 2 are provided.
When the handles 3 and 4 are closed, the gap between them is formed narrower in a direction away from the pivot 2, so that the outer edges of the cylindrical caps 16 and 16 fitted near the pivot 2 are formed. Since the gap is also narrower in the direction away from the pivot 2, the opening / closing angle of the outer edges of the cylindrical caps 16, 16 is smaller than that, even when the handles 3, 4 are fully opened. Therefore, pivot axis
2 When the grips 3 and 4 in the vicinity are held, there is an advantage that the grips 3 and 4 can be securely held without slipping, and the closing operation of the grips 3 and 4 can be reliably performed. Moreover, in the vicinity of the pivot 2 of the cylindrical caps 16,16,
Since the projections 17,... Are provided, there is an advantage that the hand can be further prevented from slipping by the projections 17,.

Note that the hand tool according to the present invention is not limited to the crimping type hand tool according to the above embodiment, and other hand tools such as a manual cutting tool and a cable cutting layer are cut. Tools and pliers.

In the above embodiment, the claw 11 is formed as a convex arc, and the tooth surface 7a is formed as a concave arc having the same radius as the claw 11, but the tooth surfaces of the claw 11 and the ratchet 7 are formed. 7a
The shape is not limited as long as the shape is in contact with the surface.

Further, in the above embodiment, the handle 3
Although a locking hole 15 is formed in the hole, one end of the coil spring 14 is locked in the hole. However, the holding portion of the coil spring 14 is not limited to this. For example, a tongue piece punched and formed in a part of the handle 3 May be used as a holding portion, and the coil spring 14 may be engaged with the holding portion.

In the above embodiment, the handle 4
Is formed in a substantially U-shape in cross-section by bending a flat plate, but the shape of the handle 4 is not limited to this, and can be changed as appropriate. Bends to reduce the distance between the edges 4c
By making the shapes of 4c and 4c superimposed on each other, the handle 4 has a tubular shape or a shape close to a tubular shape, and the strength of the handle 4 can be increased.

[0047]

An arcuate ratchet centered on the pivot is formed integrally with the handle, so the number of parts can be reduced,
Therefore, assembling work can be simplified, and
It can be manufactured at low cost.

Further, since the ratchet is used for machining the teeth of the ratchet with reference to the pivot shaft,
Accuracy of the ratchet with respect to the pivot which is the center of rotation of the handle can be ensured. And it can be assembled quickly.

The manual tool according to the present invention is characterized in that
As described, to make the nail and ratchet tooth surface abut,
Because the shape of the nail and / or tooth surface is set, even if the handle is forcibly opened, the outer edge of the nail does not come into line contact with the tooth surface, and therefore, the outer edge of the nail hits the tooth surface locally. Can be suitably prevented from being caused on the tooth surface.

Further, in the manual tool according to the present invention, when the ratchet and the claw are engaged with each other,
Since the first ratchet is engaged with the first claw and the second ratchet is engaged with the second claw, the force can be distributed to two places, and therefore, the durability of the ratchet and the claw can be increased. Can be.

The manual tool according to the present invention is characterized in that
As described, the first ratchet and the second ratchet are formed so as to have different phases from each other in the direction around the axis of the pivot shaft, and thus constitute a ratchet having a half pitch of the pitch of the first ratchet and the second ratchet. It is possible to change the opening / closing angle of the handle at a smaller angle.

Further, the hand tool according to the present invention employs a handle formed by bending a metal flat plate into a substantially U-shape in cross-section, so that the axial length of the pivot shaft is set. The first ratchet and the second ratchet facing each other in the direction can be easily carved, and when carving the first ratchet and the second ratchet, the handle is rotated with reference to the pivot shaft. The accuracy of the ratchet with respect to the central pivot can be ensured.

Further, the hand tool according to the present invention is provided in claim 6.
As described, since the rotating body is formed by press-forming a metal strip, it is cheaper and simpler than the conventional one formed by a sintering method or a lost wax method. Can be formed.

Further, in the hand tool according to the present invention, since the holding portion is formed on the handle to hold the elastic body, the holding tool is fixed to the support pin fixed to the handle as in the prior art. By not holding the body but holding the body directly on the holding portion, parts such as the support pins can be eliminated, and therefore, the assembly work can be simplified by reducing the number of parts, and It can be manufactured at low cost.

Further, the manual tool according to the present invention is provided in claim 8.
As described, an arc-shaped convex portion is formed on one of the pressing elements,
Since the other pressing member is formed with an arc-shaped concave portion into which the convex portion can be engaged, it is possible to prevent the pressing members from being shifted from each other, and it is not necessary to separately provide a pin as in the related art. The number of points can be reduced, so that the assembling work can be simplified and the device can be manufactured at low cost.
