New description: [New technical field] This creation is about a kind of power ratchet wrench, especially the ratchet device of the power ratchet wrench. [Prior Art] The utility model uses a pneumatic motor or the like to provide rotational power, drives the ratchet device to reciprocate, and then uses a ratchet device to steer the workpiece in one direction, thereby facilitating assembly or disassembly of the screw. Nut or similar workpiece. The existing power ratchet wrench can refer to US5448930 patent, which is to connect the sleeve with a ratchet to further connect the sleeve, thereby quickly loading and unloading the screw. However, in the power ratchet wrench, the ratchet can only rotate the sleeve in one direction, if the user If you want to remove the screw and then accidentally distorted the power ratchet wrench, you must first remove the power ratchet wrench from the screw and turn it back again. However, in actual use, the screw is often set to long. There are other items on the sides of the rod or the screw. The user needs to disassemble and install the power ratchet wrench twice for each time the user installs and removes the screw, which causes the big trouble in the actual use. In this regard, US Pat. No. 4,722,252 provides a through-hole power spindle in which, in addition to having a motion field and a ratchet, a commutation device having a group-ratchet switching direction can be used to switch the reversing device to change the ratchet. In the working direction 'Using this device', the user does not need to repeatedly turn the power ratchet wrench (4) and turn when disassembling the screw. It is convenient to change the direction of rotation of the piece by changing the switching position. However, the reversing skirt is disposed in the accommodating space between the two end faces of the head. In order to allow the user to toggle the slanting direction, the user must exceed the accommodating space and protrude from the outer surface of the head. Actually, the (4) 'switching device will follow the part of the lion with the power ratchet device, and the head will protrude outwards. The county is easy to be _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The meshing is not correct, or the working direction of the ratchet is arbitrarily changed, causing the operation to cause (4) troubles. Secondly, the external device of the reversing device is also easy to touch with other people, or colliding with the manufacturer, causing accidental injury or property damage. There are 4i here, and the creator has previously proposed the No. 1 patent. The patent's main money touches the kind of through hole and makes it difficult to set the hand. It is to set the switching piece of the adjustment ratchet to the working county, and the switcher can switch the switch. The switching member does not arbitrarily shake the material, and the collision between the city member and other surrounding devices or workpieces can be avoided, which has a stable and good use effect. However, when the power ratchet wrench is used, the switching member still needs to protrude. On the surface of the work surface, there are still situations in which it is easy to paste other devices and accidentally switch, especially when used in a narrow working environment, it is more necessary to pay special attention to such accidental switching, and cause user operation.

The power unit 2 is rotated between the two tears 16 of the housing. The shaft 21 has an eccentric head 211. The eccentric head 211 is engaged with the slot 315 of the swing arm 311 when the shaft is 2° b. The eccentric 211 will be rotated around the rotating shaft 21 to further drive the pendulum (four) 1 and the turning mechanism 3 to reciprocately swing. In the above, when the user operates the rotating screw, the driving wheel 32 can be sleeved on the screw or engaged with the screw, and then the power unit 2 is activated, so that the power unit 2 drives the turning mechanism 3 to reciprocate. 'Please refer to the figure*, the ratchet portion 33 in the rotating mechanism is in the first position, because the ratchet portion 33 in the turning mechanism only drives the driving wheel 32 to rotate in the left-hand direction, so that the turning mechanism can drive the screw Wait for the workpiece to rotate in the left-hand direction. Referring to FIG. 5, when the user wants to change the direction of rotation of the workpiece, the rotating member 41 can be rotated to the right-handed position, and the inclined surface of the rotating member 41 can be pushed against the corresponding push rod 42 to make the push rod C1. Abutting against the convex portion 413 on one side of the inclined surface 411, the push rod 421 is abutted against the pawl portion 33, thereby changing the position of the pawl portion %, so that the pawl portion 33 is cut to the second position, at this time, the pawl The part % can only be recorded along the right-hand side (4), and the workpiece can be rotated in the right-hand direction when the swinging mechanism is swung. Referring to FIG. 4, when the user wants to change the direction of rotation of the workpiece again, 'the rotating member 41 can be rotated in the opposite direction to rotate the rotating member 41 to the left-handed position, and the other inclined surface 411 of the rotating member 41 is pushed. The other corresponding push rod 421 'buts the push rod 421' against the other convex portion, and makes the push rod similar, and switches the pawl π 33 to the first position, so that the swing mechanism can drive the screw when reciprocating The workpiece such as firmware is rotated in the left-hand direction. In summary, the present invention can be used by the user to change the direction in which the workpiece is rotated by using the rotating member 41, wherein the rotation is performed by a rotating member 41 that can be rotated in the radial direction, and the rotating member 41 can be set. It is a ring shape, and the rotating member 41 can be arranged around the inscription _ part u, and its outer shape does not protrude directly from the surface of the casing 1 'Ke Yi _ other objects are stuck, which is more suitable for the narrow working environment towel Fine, but can be used in a narrow need for use. f. The rotating member MS used for the adjustment in the present invention is provided for the user to rotate into the 仃 operation. The ke needs to be turned _ _ self-material will be exposed to the surface of the casing 1 to avoid accidental contact with other devices around. In the case where the rotation direction is arbitrarily switched and changed, the operation effect is stable, and the work of rotating the screw firmware can be surely performed according to the use of the surface, and the use effect is excellent.
