Description

  The present invention relates to work tweezers, and more particularly to work tweezers used for work for processing fine members.

  For example, work tweezers are used during processing associated with the installation of optical fiber connectors for telephone lines that handle relatively small components, but work using an external light source such as a flashlight when the work place is in a dark place May do. However, the use of a flashlight hinders work when parts such as the optical fiber connector need to be handled accurately and quickly. For example, it is necessary to work with a flashlight with one hand, or it is necessary to install a flashlight to illuminate the work target. In addition, with normal indoor lighting, the brightness of the work location may be insufficient.

  In order to solve the problem of the technique using such an external light source, a technique in which a light emitting light is attached to tweezers itself has been proposed.

  A technical example of tweezers provided with this light emitting light is disclosed in Patent Document 1. This has a structure including a tweezers body and a case for storing the tweezers, a light for illuminating a work point, a switch for turning on the light is provided in the tweezers itself, and a spring for taking in and out the tweezers is provided in the case. Is. These members constitute one tweezers. The tweezers light is attached to the tip of the case, and the switch is provided at the base end of the case and is configured as a rotary switch that is operated by rotating.

  Another technical example is disclosed in Patent Document 2. This tweezers has a bipod-shaped sandwiching hand made entirely of a photoconductive synthetic resin and a gripping hand continuous with the proximal end of the sandwiching hand. The light projecting unit is provided in the gripping hand so as to project light from the proximal end side to the distal end side of the gripping hand. The switch shown in the document operates by rotating a cap fitted to a main body case constituting a gripping hand by a predetermined angle.

Japanese Patent No. 3110371 JP 10-165409 A

  However, in the techniques disclosed in the above-mentioned Patent Documents 1 and 2, it is necessary to rotate the rotary switch or the cap to turn on the switch, and these operations hinder smooth and continuous tweezer work. It is.

  For example, when turning on the light provided in the tweezers during work, it is necessary to change the tweezers held by one hand and rotate the rotating cap or the like with the other hand. In the opposite case, that is, when the light is extinguished, the same operation is necessary, and these operations cause a concentration force necessary for the work of processing a fine member.

  SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and an object thereof is to provide work tweezers that can be easily turned on and off and that can be operated while maintaining smoothness and continuity. There is to do.

  The working tweezers according to claim 1, which achieve the above object, are working tweezers in which a light emitting unit, a power source for supplying current, and a switch for turning on and off are loaded in a main body, Provided near the tip of the arm part of the main body, the switch touched when the arm part was moved in the direction in which the arm part approached inside the arm part, and moved in the direction in which the arm part separated It is characterized in that it is sometimes provided in a non-contact state.

  Thereby, the on / off of the switch can be operated only with one hand holding the tweezers. That is, there is no need to change tweezers or perform switch operation with the other hand. Therefore, the continuity and smoothness of work are maintained.

  The working tweezers according to claim 2 are the working tweezers according to claim 1, wherein the arm part is a clamping part formed at the tip part and a user formed wider than the clamping part. The light emitting unit is provided so as not to protrude from the height in the width direction of the arm unit at a position near the boundary between the holding unit and the gripping unit.

  Thereby, for example, when the tweezers are placed on a desk, a protection state can be formed to prevent the light emitting section from directly hitting the desk surface, and damage to the light emitting section can be prevented. Further, since the light emitting part does not protrude from the arm part in the height direction, it is possible to prevent the irradiated light from directly entering the eye.

  The working tweezers according to claim 3 are the working tweezers according to claim 2, wherein a protruding portion having a height in the width direction higher than other portions is formed near the light emitting portion of the grip portion. It is characterized by.

  Thereby, the protection state of a light emission part can be made more reliable. That is, for example, when the tweezers is placed on a desk, the convex part of the tweezers hits the desk surface, and the light emitting unit is protected from hitting the desk surface. In addition, the presence of the protruding portion enhances the function of preventing the light emitted from the light emitting portion from directly entering the eye.

  The working tweezers according to claim 4 are the working tweezers according to any one of claims 1 to 3, wherein the power source is housed in the casing and is located on the outer surface near the base end of one arm portion. The fixed casing is characterized by having an installation stabilizing portion extending from the bottom portion thereof in a direction perpendicular to the length direction of the arm portion.

  Thereby, since the installation stabilization part is provided, when this tweezers is mounted, for example on a desk, there is no backlash and stable mounting and storage are possible.

  According to the working tweezers of the present invention, it is easy to turn on and off the light emitting unit, and it is possible to perform work while maintaining smoothness and continuity of the work.

  Embodiments according to the present invention will be described below in detail with reference to the drawings. FIG. 1 is a perspective view showing a configuration of a working tweezers according to the present embodiment, and FIGS. 2 and 3 are a top view and a side view of the tweezers.

  As shown in FIG. 1, the tweezers 10 has a main body having an arm portion 12 for holding a member by a holding portion 24 provided at a distal end portion. A casing 14 that houses the battery is fixed to the outer surface of the arm 12 near the base end.

  Light emitting portions 18 are provided on the proximal end sides of the clamping portions 24 of both arm portions 12, respectively. The light emitting unit 18 is installed so as to illuminate the direction of the tip of the tweezers 10, and a light emitting diode (LED) is used in the present embodiment.

  A switch 20 for turning on and off the light emitting unit 18 will be described with reference to the drawings. The switch 20 which is a component of the present invention is provided on each inner surface of the arm portion 12. The installation positions of these switches 20 are opposite to each other, and are positions that come into contact when the arm portion 12 is moved in the approaching direction and are in a non-contact state when the arm portion 12 moves in the separating direction. . Each switch 20 is provided with a plate-like ridge portion 20a as a contact, and the contact separation operation is more reliably performed.

  The connection wiring of each member is performed by connecting the battery in the casing 14, the switch 20, and the light emitting unit 18 through the connection line 22, and the connection line 22 is installed along the arm 12.

  Here, the two members 20-1 and 20-2 constituting the switch 20 may be anything as long as they contact each other and conduct electricity. For example, the ridge 20a is a spiral spring or a commercially available switch. May be.

  With this configuration, the switch can be turned on and off while holding the tweezers 10 so as to pick the target part, and the tweezers 10 can be operated quickly and easily without requiring any special operation for turning on and off.

  Here, the arm portion 12 has a gripping portion 26 for the user to grip (see FIGS. 1 and 3). The grip portion 26 is formed wider than the sandwiching portion 24, and thus a stepped portion 28 is formed at the boundary position between the sandwich portion 24 and the grip portion 26. The light emitting unit 18 is fixed to the stepped portion 28 so as to illuminate the tip portion direction of the tweezers 10 (see FIG. 3).

  Here, the height a of the light emitting portion 18 is set to a height that does not protrude from the end surface 30 in the width direction of the arm portion 12 (shown by a dotted line in the vicinity of the step portion 28). In the present embodiment, the width (thickness) of the light emitting portion 18 is set to be approximately equal to the thickness b of the arm portion 12 (see FIG. 2).

  Thus, for example, even if the tweezers 10 is placed on a desk with the light emitting portion 18 facing downward, the light emitting portion 18 does not directly hit the desk surface, and therefore the light emitting portion 18 is protected from damage due to hitting the desk surface.

  Further, by fixing the light emitting portion 18 at this position, the light of the light emitting portion is not obstructed by the grip portion 26 and the periphery of the tip portion of the tweezers 10 can be reliably illuminated. Further, since the light emitting unit 18 becomes a shadow of the stepped portion 28 on the gripping portion 26 side of the tweezers 10, the light emitted from the light emitting unit is effectively prevented from directly entering the eye.

  Note that, as described above, the light emitting portion 18 is formed of an LED, so that miniaturization and simplification are facilitated. Furthermore, when compared with a miniature light bulb, the strength against impact is improved, and breakage of this portion is more reliably prevented.

  Further, in the present embodiment, a protruding portion 32 having a height in the width direction higher than other portions of the gripping portion 26 is formed in a portion of the gripping portion 26 near the light emitting portion 18 installation position (see FIGS. 1 and 3). ). This is for ensuring the above-described protection state of the light emitting portion 18 by the protruding portion 32. That is, for example, when the tweezers 10 is placed on a desk with the light emitting section 18 facing downward, the projecting section 32 hits the desk and the light emitting section 18 does not directly hit. It also leads to more effective prevention of light directly entering the eye.

  The casing 14 is provided at a location where the work is not hindered, that is, the outer side surface of the proximal end portion of the tweezers 10. An installation stabilizing portion 34 for stably placing the tweezers 10 is provided on the bottom portion 14 a of the casing so as to extend in a direction perpendicular to the length direction of the tweezers 10. As a result, when the tweezers 10 is placed on a desk with the installation stabilizing portion 34 facing down, for example, the tweezers 10 can be stably placed without rattling and stable storage is possible. In the present embodiment, the button battery is used as the battery, thereby making the casing compact and reducing the weight of the tweezers 10 and making the battery easy to replace.

  According to the tweezers 10 according to the above embodiment, the light emitting unit can be turned on and off while continuing the operation, that is, with the tweezers 10 being held. Therefore, it is possible to perform the operation as a continuous operation without interrupting the concentration necessary for the operation of processing the fine members.

  Further, since the light emitting unit 18 is protected by the shape of the tweezers 10 and is fixed so that the irradiation light does not directly enter the eye and illuminates the tip direction of the tweezers 10, workability is also improved.

  In addition, the structure of this invention is not limited to the structure of the said embodiment, A various deformation | transformation is possible within the range of the summary of invention. For example, the installation stabilization part 34 provided in the bottom part 14a of the casing 14 can be provided also in the upper surface part of the position which opposes the bottom part 14a other than this location.

  The working tweezers according to the present invention is effectively used in processing of fine members such as processing accompanying installation of a fiber optic connector of a telephone line. Also, in other cases than the above, it can be widely used as a working tweezers.
