The working principle is as follows:
the first step is as follows: when the hand-held tool mechanism 1 is used, the wrist is lapped at the rear end position of the hand support 301, the thumb is placed at the pull plate 207, the hand-held tool mechanism is used according to common tools when being used manually, when the hand-held tool mechanism is used electrically, the pull plate 207 can be pushed forwards through the thumb, then the thumb belly is directly pressed downwards to press the switch button 201 downwards, the switch button 201 is enabled to be simultaneously connected with the battery bin 106 and the conductive plate 108, internal circuits of the hand-held electric tool are connected, the tool head 111 is driven by the motor 110 to rotate, and only the thumb needs to be removed and pressed, under the action of the first spring 202 and the second spring 206, the switch cover 205 and the switch button 201 can be automatically reset, the device can be used in an automatic and manual isolation mode, and can be operated by a single hand, and the use is simple and convenient.
The second step: after the switch button 201 is pressed down to start the electric mode, the coil 503 is electrified through the connection of the lead 504, at the moment, the fixed iron core 502 attracts the movable iron core 506 to move backwards, the left end of the swinging plate 601 is pulled towards the back side through the connection of the small column 607, the right end of the opposite swinging plate 601 moves towards the front side, the positioning mechanism 7 is pushed towards the front side integrally, the positioning block 704 is positioned at the front side of the tip of the tool head 111, so that when the electric operation is carried out through a tool, the positioning of the position of the tip of the tool head 111 can be firstly carried out through the positioning blocks 704 at the two sides, and the working accuracy of the tool is improved.
The third step: after the switch button 201 is pressed down, the tool head 111 is rotated and started immediately, and meanwhile the positioning block 704 extends to the front of the tool head 111, so that the positioning mechanisms 7 on the two sides surround the tool head 111, on one hand, the tool head 111 is protected, on the other hand, the situation that a worker mistakenly touches the tool head 111 to cause harm is avoided, and the use safety of the tool is improved.
The fourth step: when the tool is held by hand, the wrist of the operator can be lapped on the clamping bag 303, so that the operator does not need to be suspended for working, and the use comfort of the operator is improved.
The fifth step: after the switch button 201 is started, the fixed iron core 502 attracts the movable iron core 506 to move backwards, so that all air between the movable iron core 506 and the fixed iron core 502 is guided into the clamping bag 303 through the air pipe 507, at the moment, through the existence of the air bag 304, the whole area of the inflated air bag 304 is larger than the arc surface of the side, away from the hand support 301, of the clamping bag 303, so that the end, away from the hand support 301, of the clamping bag 303 is upwards turned, the wrist of an operator is clamped from two sides, the wrist of the operator is fixed, a tool and the hand of the operator can be locked, manual operation and electric operation are prevented from being performed simultaneously, power resource waste is avoided, the wrist of the operator is prevented from being strained, and the use safety of the device is improved.
And a sixth step: when the tool is manually operated, the switch button 201 is not started, and the positioning block 704 is positioned at the rear side of the tip of the tool head 111, so that the tool head 111 is not obstructed to be used in the manual operation, and the device is very convenient to operate independently.
The seventh step: through the existence of protector to when manual operation, when needing to insert to close the rotation to the target, the holistic specification of device has been widened to the protection machanism of both sides, thereby is convenient for hold the instrument and rotate it, puts forth effort when convenient the rotation, makes more laborsaving when instrument manual rotation uses.
