TW200529983A - Improved rotation structure of screwdriver - Google Patents

Abstract

An improved rotation structure of a screwdriver (2) mainly includes: a handle, an intermediate control rod, a ratchet component, a rotation rod, and a moment arm, in which the handle is formed with a through hole, the intermediate control rod is mountable in the through hole of the handle, the front end of the intermediate control rod is formed with a control aperture with a suitable depth, one side of the intermediate control rod is formed with a control groove and one side is installed with a pivotal groove. The ratchet component can control the forward/reverse rotation of the rotation rod. The rotation rod is of a long cylinder shape, in which one end of the rotation rod is installed with an annular teeth part, and the whole body is pivotally mounted on the intermediate control rod. The teeth part of the rotation rod is housed in the control groove of the intermediate control rod. The teeth part of the rotation rod can be driven by the ratchet component to rotate. The moment arm is pivotally mounted on the pivotal groove of the intermediate control rod, and the whole body can be housed in the groove of the handle. Thus, the moment arm can be used to increase the rotation power when the screwdriver is used to drive a device in order to save power during the operation.

200529983 V. Description of the invention (4) In the jack of the push rod, a knob (: a flexible convex rod (4 1) is accommodated, and the knob can be pivoted on the control hole of the center lever (2 0). (2 4 0) of the convex rod (4 1) and pressed against the back of the card block; a rotation is provided to accommodate the groove tooth portion (5 2 tooth (3 0 (53), rod (2 0) The rotating hole (within 5), the circular hole of the rotating lever (0), a moment tip (70), the system can accommodate a tip (70, and then pivot through the moment; see section (4) for the f-zone slot as a whole) Rotate the ring groove (5 pivot at 0) and pivot (50) (11) (60) to the tooth-locking lever (50 (51)) to make it) against the clamping block. In the middle of the grip body () is wearable (60) (23) After the right rotation of the third picture as shown in the figure (30) After turning the lever and the 5 3 setting, its control is over 1

930227 screwdriver ratchet two ptd page 8 4 〇 is a long cylindrical shape, and is opened in the receiving slot (5 1) at the tail end position. It is equipped with a ring-shaped clamping block (3 0). And a ring groove is set in the receiving groove (5 1) for buckle J 2 (2 8) to set, so that the receiving groove (51) of the middle lever (50) is inside the holding body (1 0) The through hole (1 2) 'the receiving groove (5 1) is received in the grip body (丄 f has a round hole (6 1) at one end so that it can be caused by the pivot groove (2 3) of the rod (20)) , 敕 0) groove (1 3); ^ pivot hole (2 4), circular hole (6 1) of the center lever (2 0), so that the moment (6 0) f, as shown in the second figure Show. This is a schematic diagram of the operation of the present invention. The convex rod (41) of the knob (40): on the two rear sides, the clamping block (3 0) is forced: 50) the tooth portion of the receiving groove (51) 1 200529983 L, Description of the invention (5) 2), if the direction is rotated (2 0), the rotation lever is rotated (moving to move the middle block (3 〇)) clockwise, please refer to the time, force (3 0) to The lever (the grip body (1 with the power of the ratchet) has the function of 'grip the body, middle 50'). The lever (the action of the fourth picture knob (one side, 50)) is only effective. Efficacy, (1 0) is due to the counterclockwise rotation of the force control lever (2 0), and the phenomenon of tooth jumping occurs when 2) is rotated, otherwise, the convex rod of 4 0) now blocks the block (receiving slot ( 5 1 This counterclockwise direction is also the gripping moment (60) because the card block is used as the gripping body (, the center lever cannot be used to rotate the teeth of the knob ((41) 3 0))) and ( 310 (2 rotations 4 0 against one side (5 levers (〇) to drive 〇)) to move ○) to the system of the card 0 counterclockwise center lever and can be rotated clockwise due to the system (50 left rotation Make the teeth snap on, such as), and not) immediately Said Xia this force (the rod (Ming continues to refer to the fifth figure), the moment is considered when the moment (60) is unfolded from the grip body (), and it will be displayed in the middle of the movement, P bow mouth * 丄 瓶, ιυ) The groove is diligent and sweaty, and the moment (60) can directly drive the center bar η 3 and rotate the card block (30) and rotate the rotation # 工 干 (20). The moment due to the moment (6 〇), such as 〇) "The body 10 moment (60) has been unfolded, the body grip moment (60) is separated and the grip body (1 π) life # ^ 0) is the pivot It is shaped, and the hand is held on the grip body (1, 2, Π \ X3 P ，, the grip body) is free to rotate, and there is no friction between the palm, which is a great advantage. This is the present hair V-the embodiment, Department, month, month, and long-term refer to the sixth figure, which is based on this-

200529983 V. Description of the invention (6) Both sides of the grip body (10) have moments (6) Two sides have grooves (1 3), the center lever ((2 3)) and pivot holes (2 4), moments (The same effect can also be achieved during implementation. Continue to refer to the seventh figure, which is the fourth embodiment of the present invention. The rotating lever (5 lever (50) is fixed to the grip body (i)). A set of winged rods (80) is fixed on it. When the rotating lever (50) is connected, the M: (60) drives the center lever (3 = grip body (1 0) as the eighth As shown in the figure. The control forward and reverse structure of the present invention, such as (30) and the knob (40), has quite a lot of structures that cannot be patented. Therefore, no control forward or reverse structure is enclosed, and its control is The reversal structure is slightly changed in composition. The greatest advantage of the present invention is that: 1. Because the present invention is attached to the grip body ((60)), it can be used for 柞 # 击, 丄 U for yoke moving screw. (6 0) can increase the power of rotation. 2. When the moment (60) is hidden behind the recessed body (80), the rotation lever can be rotated: the rotation mode of a 5 J screwdriver is the same, but When the unfolding force is 0) 2 0 6 0 this hair 0), and the moment of rotation (the first rotation but the description should be centered, that is, the grip body (1 0) also has pivot grooves on both sides) can be unfolded, the whole implementation of the third For example, it has wings, which make it rotate the grip body (10), and the front grip body (10) is straight 60), the rotation torque is the rotation lever (50) and the figure shows the control of a screwdriver like a control block. In the content of reversal-write, when the action (1) of the protective lever (20) in the knot of the present invention is within the moment (when a torque is added to one side, the torque can be expanded 3), this operation is rotated and held The way is to rotate power with a 60)

930227 screwdriver ratchet II. Ptd page 10 200529983 V. Description of the invention (7) Moment of rotation (6 0) and turning the rotation lever (50) to increase its torque and unfolding torque (60) also has a ratchet effect. The invention has two kinds of rotation modes in structure. 3. As shown in the second figure, the center lever (20), the control block (30), the knob (40), and the torque (60) are all hidden on the grip body (10) to make it look good. Aesthetic effect. In summary, the present invention has both novel and practical effects, and can improve the shortcomings of habitual use. It is indeed an excellent invention that can meet the requirements of an invention patent. An application is filed in accordance with the law. Scrutinize carefully and pray for granting a quasi-patent early!
