Abstract

<P>PROBLEM TO BE SOLVED: To provide an electric screwdriver with a means which only requires to press a tip of the electric screw driver onto a screw to be automatically activated to rotate. <P>SOLUTION: When a bit 12 at a tip of a spindle 10 is pressed onto the screw, a spring 5 provided to a rear part of a motor 2 is interlockingly expanded and contracted, and a push button switch 4 is pressed down by an iron core protection cap 6 at the rear part of the motor 2 to power the motor 2 for activation and rotation. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

本発明品は電動ドライバーに関するものである。 The product of the present invention relates to an electric screwdriver.

従来式の電動ドライバーはビス等を止める際スイッチを手動で入力する必要がある。この例として、特許文献１に開示されているものがある。
特開平７−６０６５３ The conventional electric screwdriver needs to manually input a switch when stopping a screw or the like. An example of this is disclosed in Patent Document 1.
JP 7-60653 A

電動ドライバーの先端部をビスに押さえつけるだけで、自動に起動回転する手段を設ける Provide a means to automatically start and rotate just by pressing the tip of the electric screwdriver against the screw

Means to solve the problem

ビスにスピンドル１０先端部のビット１２を押し付けると、これに連動してモーター２後部に備えられたバネ５が伸縮し、モーター２後部の鉄心保護キャップ６で押しボタンスイッチ４が押し込まれ、モーター２に電気が流れ起動回転する構造とした。 When the bit 12 at the tip of the spindle 10 is pressed against the screw, the spring 5 provided at the rear of the motor 2 expands and contracts in conjunction with this, and the push button switch 4 is pushed in by the iron core protection cap 6 at the rear of the motor 2. In this structure, electricity starts and rotates.

The invention's effect

以上にすることでビスにスピンドル１０先端部のビット１２を押し込むだけで、モーター２はバネ５を押さえつけ、モーター２後部にある鉄心保護キャップ６で、押しボタンスイッチ４を押し込むため、モーター２に電気が流れ回転し、簡単にビスを締め付けることができる。 By simply pushing the bit 12 at the tip of the spindle 10 into the screw, the motor 2 presses the spring 5 and pushes the push button switch 4 with the iron core protective cap 6 at the rear of the motor 2, so Rotates and can be easily tightened.

またビスからスピンドル１０先端部のビット１２を放すとモーター２後部のバネ５が反発し、モーター２の鉄心保護キャップ６は押しボタンスイッチ４から離れ、モーター２の電気は遮断されるため回転は自動で止まる。 When the bit 12 at the tip of the spindle 10 is released from the screw, the spring 5 at the rear of the motor 2 is repelled, the iron core protection cap 6 of the motor 2 moves away from the push button switch 4, and the electricity of the motor 2 is cut off so that the rotation is automatic. Stop at.

図２はスピンドル１０の後部に直接押しボタンスイッチ４を設けた図である。スピンドル１０とモーター軸心１３を歯車１５で組み合わせ、スピンドル１０の後部にスピンドル軸受けキャップ１４を設け、スピンドル１０を押し込んだ時に、バネ５が縮み、押しボタンスイッチ４がスピンドル軸受けキャップ１４で押される事でモーター２に電気が流れ、起動回転する事ができる。 FIG. 2 is a view in which a push button switch 4 is provided directly at the rear part of the spindle 10. The spindle 10 and the motor shaft 13 are combined with a gear 15, and a spindle bearing cap 14 is provided at the rear part of the spindle 10. When the spindle 10 is pushed in, the spring 5 is contracted and the push button switch 4 is pushed by the spindle bearing cap 14. Then electricity flows to the motor 2 and it can start and rotate.

Best mode for practicing the invention

ビット１２は磁気を帯びており、ビット１２にビスを吸着固定することができる。ビスを吸着した状態でビス穴に差込み、ノッキング電動ドライバー１を垂直に押し込むとモーター２はバネ５を押さえつけ、モーター２後部にある鉄心保護キャップ６で、押しボタンスイッチ４を押し込むため、モーター２に電気が流れ回転し、ビス止めをすることができる。 The bit 12 is magnetized, and screws can be fixed to the bit 12 by suction. When the screw is inserted into the screw hole and the knocking electric screwdriver 1 is pushed vertically, the motor 2 presses the spring 5, and the push button switch 4 is pushed in by the iron core protective cap 6 at the rear of the motor 2. Electricity flows and rotates and can be screwed.

またビスを抜く場合には正逆回転切り換えスイッチ８を逆回転に切り換え、ビスにノッキング電動ドライバー１のビット１２を差込み、垂直に押し込めば逆回転し抜く事ができる。 Further, when the screw is pulled out, the forward / reverse rotation changeover switch 8 is switched to the reverse rotation, the bit 12 of the knocking electric screwdriver 1 is inserted into the screw, and if it is pushed vertically, the reverse rotation can be pulled out.

スピンドル１０の先端部のビット受け１１をチャック式にすることで穴あけ用ドリルなどに応用できる。 The bit receiver 11 at the tip of the spindle 10 can be applied to a drill for drilling by making it a chuck type.
