Like the battery V, the external device mounting adapter 4 has a bulging portion 4P ( upper front ), a lever 4L, adapter claws and elastic bodies, slide grooves, and terminal grooves with power supply terminals. are doing. An end portion 6B of the power cord 6 on the side of the external device mounting adapter is connected to the rear end portion of the external device mounting adapter 4 . Each power wire of the power cord 6 is electrically connected to a corresponding power terminal of the adapter 4 for attaching an external device.
On the other hand, an external device such as a screwdriver SD has a battery mounting part SDI having a slide rail and a terminal with a terminal rail, like the battery mounting part 12 of the battery mounting adapter 2 .
The external device mounting adapter 4 is mounted on the battery mounting part SDI so that each slide groove fits into the corresponding slide rail and each terminal groove fits into the corresponding terminal rail. It contacts and is electrically connected to the terminal rail. Therefore, an external device such as a screwdriver SD is connected to each terminal rail of the battery mounting portion SDI, each power terminal of the external device mounting adapter 4, each power line of the power cord 6, and the battery mounting portion of the battery mounting adapter 2. It is electrically connected to the power supply terminal of the battery V via each of the 12 terminal rails. The external device attachment adapter 4 does not have a battery cell and is lighter than the battery V (for example, 500 grams lighter).
Connection terminals that can be connected to each other are provided at an external device such as a screwdriver SD and the rear end of the power cord 6 (an end portion 6B on the side of the external device mounting adapter). Adapter 4 may be omitted. In addition, the external device mounting adapter 4 and the external device mounting adapter side end portion 6B of the power cord 6 are provided with connection terminals that can be connected to each other, so that the power cord 6 can be attached to and detached from the external device mounting adapter 4. It may be possible.

An operation example of the battery adapter 1 described above will be described.
When the operator attaches the external device attachment adapter 4 to the external device of the screwdriver SD and attaches the battery V to the battery attachment portion 12 of the battery attachment adapter 2, the power of the battery V is transferred to the battery attachment adapter 2, The power is supplied to the external device of the screwdriver SD via the power cord 6 and the adapter 4 for mounting the external device, so that the external device of the screwdriver SD can be used.
The worker attaches the battery mounting adapter 2 with the battery V to the worker by hooking the first hook 16 on a belt or the like wrapped around the worker or by hooking the second hook 18 on a hook or the like at the work site. The weight of the battery mounting adapter 2 with the battery V can be held by the operator or the like, and the weight of the battery mounting adapter 2 with the battery V can be applied to the operator or the like instead of the external device. Therefore, the operator can use the external device of the screwdriver SD in a lighter state than when the battery V is attached to the external device. In particular, when a screwdriver SD or the like is used to tighten screws in a remote location such as a ceiling, the effect of reducing the weight of the external device is great, and the burden on the operator is remarkably reduced. In addition, the operator can hang the battery mounting adapter 2 with the battery V on the first hook 16 or the second hook 18, depending on at least one of the environment of the work site and the condition of the operator. A battery mounting adapter 2 with a battery V can be hung.
Further, since the ridge 10a is provided on the opposite surface of the first hook 16, the object to be hooked such as a belt is firmly held when hooked by the first hook 16, and the battery mounting adapter 2 with the battery V is attached. It can be hung on the object to be hung more reliably.

The battery adapter 1 described above includes a battery mounting adapter 2 having a battery mounting portion 12 to which a battery V can be mounted, a battery mounting adapter 2, and a power cord 6 connected to the external device mounting adapter 4. The battery mounting adapter 2 has a first hook 16 and a second hook 18 . Therefore, in the battery adapter 1, the battery mounting adapter 2 to which the battery V can be mounted is held in a manner in which the first hook 16 is hooked and a manner in which the second hook 18 is hooked. Either mode can be selected accordingly.
Further, the second hook 18 is rotatable around the left mounting portion 18L and the right mounting portion 18R with respect to the battery mounting adapter 2, and is held so as to change its posture. Therefore, the battery mounting adapter 2 can be hung by the second hook 18 on a wall surface, a slope, or a hook installed at the tip of a rope at a work site.
Additionally, the second hook 18 is held against the first hook 16 . Therefore, the battery mounting adapter 2 having the first hook 16 and the second hook 18 becomes more compact.

In addition, the battery adapter 1 includes a battery mounting adapter 2 having a battery mounting portion 12 to which a battery V can be mounted, a power cord 6 connected to the battery mounting adapter 2, and the external device mounting adapter 4, and a second hook 18 held so as to be able to change its attitude with respect to the battery mounting adapter 2. The battery mounting adapter 2 includes a left main body housing 20L and a right main body housing 20L fixed to the left main body housing 20L. The second hook 18 does not overlap the right body housing 20R in the direction (rightward) in which the right body housing 20R separates from the left body housing 20L. It is possible to take a non-interference posture (FIG. 5), and if the separation non-interference posture is not taken, the left main body portion is positioned in the direction (rightward) in which the right main body housing 20R separates from the left main body housing 20L. It overlaps with the housing 20L and the right main body housing 20R. Therefore, in a normal state, even if the right main body housing 20R tries to be separated from the left main body housing 20L, the second hook 18 interferes with the right main body housing 20R to prevent the separation, and the left main body housing 20L and the right main body housing 20L are separated from each other. The united state of the main body housing 20R is maintained, and the united state can be obtained even in an emergency such as when at least one of the screw boss 22, the screw hole 24 and the screw 26 fails. In addition, in the battery adapter 1, the second hook 18 is expanded at the cut and deformed at the time of assembly as compared with the case where the ring-shaped second hook 18 with the cut is spread at the cut and inserted into the hole of the main body housing 20. Therefore, the second hook 18 can be attached naturally, and a longer attachment length (left and right length of the left attached portion 18L and left and right length of the right attached portion 18R) can be ensured.
The second hook 18 is ring-shaped with a gap, and the left main body housing 20L has a second hook mounting left hole for mounting the left mounting portion 18L, which is one end of the second hook 18. The right main body housing 20R has a second hook groove 16b for attaching a right attached portion 18R, which is the other end of the second hook 18, and the second hook 18 has only a second hook attachment left hole. It is possible to take a non-interfering posture when separated. Therefore, the second hook 18 , which can take an interfering posture during separation and a non-interfering posture during separation, can be more easily attached to the main body housing 20 .
Further, the second hook 18 is held by a protruding portion 16J provided on the battery mounting adapter 2 and protruding from other portions. Therefore, the second hook 18 that can take an interference posture during separation and a non-interference posture during separation can be easily attached to the main body housing 20 .
Furthermore, the projecting portion 16J is the base (part) of the first hook 16 (another hook) provided on the battery mounting adapter 2. As shown in FIG. Therefore, the battery mounting adapter 2 having the second hook 18 and the first hook 16 that can take the interference posture during separation and the non-interference posture during separation is formed compactly.
Also, the external device (screwdriver SD) is an electric tool. Therefore, the power tool becomes lighter than when the battery V is directly attached, and workability is improved.

In addition, the form of the present invention is not limited to the above-described first form and its modifications, and the following modifications may be made as appropriate.
The posture of the first hook 16 may be changed. Various postures of the hooks may be changed by moving the attached portion of the hook relative to the elongated hole-shaped attachment portion of the main body housing 20 instead of or together with the rotation.
The first hook 16 may be separate from the main body housing 20 .
The second hook 18 may be attached to a portion other than the first hook 16 , such as being attached to a protrusion separately provided on the main body housing 20 .
The non-interfering posture of the second hook 18 during separation is such that the groove 16b for the second hook is widened so as not to interfere with the right main body housing 20R even if the second hook 18 moves at a rotation angle of about 5° around the axis. It is also possible to cover a predetermined range by, for example,

The battery V may be a primary battery instead of a rechargeable secondary battery, a battery for electric equipment instead of a battery for power tools, a dry battery, or a built-in dry battery. It may be a dry battery pack (dummy battery) that has the same external shape as a power tool battery and can contain a dry battery (dummy battery).
When the battery V is a dummy battery, it is possible to attach a battery for an electric power tool to the battery mounting portion and also attach a dry battery through the dummy battery. In this case, the dummy battery may have only a power supply terminal for power supply, or may additionally have a battery terminal for signal, like the battery V described above.

Various screwing locations may be changed to engagement by at least one of claws and press contact. The number or arrangement of locking points or the number or arrangement of screwing points may be varied from those described above.
The shape, material, arrangement, and number of various members such as one or more power lines and power terminals, slide rails provided on the battery V and slide grooves provided on the battery mounting portion 12, etc. At least any, etc. may be varied in various ways.
External devices may be garden tools, cleaners, lights, fans, radios, speakers, compressors, and/or coffee makers.
