[Prior Art] Referring to FIG. 1 and FIG. 2, a ratchet type ratchet wrench includes a ratchet head 1, a handle body 2, a spring 3, and a steel ball 4. The ratchet head has two frames connected to the handle body 2 The pivoting end 胄1〇1, and the ratchet teeth 102 disposed on the pivoting end portion 101, the handle body 2 has a receiving hole 201 toward the ratchet teeth 1〇2. The accommodating hole 2 〇 1 β is disposed in the accommodating hole 201 and abuts against the spring 3, so that when the ratchet head 1 is rotated relative to the shank 2 to a predetermined angular position, The spring 3 forces the steel ball 4 against the ratchets 1〇2 to position the ratchet head. Although the above-described ratchet wrench can achieve the effect of the swing angle, in reality, since the steel ball 4 cannot be mutually engaged with the ratchets 2, the ratchet head 1 is not firmly positioned at a predetermined angle. In the position, when the user applies the force of the handle body 2, the accident of the rotation of the handle body 2 to the ratchet head 1 often occurs, and an unpredictable danger occurs.

The function of this month is to use the pressing of the actuating lock to control the first card and the ratchet head unit to perform the card insertion action, thereby achieving the effect of angular positioning quickly and up to the ground. [Embodiment] The following detailed description of two preferred embodiments of the present invention with reference to the accompanying drawings, in which other technical contents, features and functions are described, will be apparently disclosed in 200922752. Referring to FIG. 3 and FIG. 4, the first embodiment of the present invention includes a ratchet head unit 1A, a handle unit 20 and a positioning unit 3〇. Further, the constituent members and combined spatial patterns of the above units will be described in detail later. The ratchet head unit 10 has a body Η and a ratchet driving head 12 disposed inside the body U. The body U extends at one end thereof with a pivoting portion 1U. The pivoting portion 111 has a semi-circular shape and is at the center thereof. A shaft hole 2 is provided, and a plurality of toothed portions jj 3 are provided at the outer circumference. The handle unit 20 includes a handle 21 and a shaft pin 22 having a grip end 211 for gripping the hand at the rear end of the grip 2!, the front end having a forward end extending from the grip end 211 The pivoting end 212 is convex toward the front and has an ear portion 213. The pivoting portion is inserted between the two ear portions 213, and a shaft hole 214 is disposed in the center of the two ear portions 213. The ratchet head unit 1〇 and the grip unit 2〇 are mutually pivoted by the shaft pin 22 penetrating into the shaft holes 112 and 214. (4) (4) Η 5 The side of the rotating end 212 is disposed laterally near the ear portion 213. - a pin hole 215 is provided at the outer side of the pin hole 215 - a counterbore 216 having a larger diameter. The center of the front end of the pivot end 212 is recessed in the longitudinal direction and is provided with a first receiving hole 217 extending through the pin hole 215. The second receiving hole 218 is deeply recessed in the middle of the connecting end 212 from the pin hole ^ toward the grip end 211. The positioning unit 30 includes an actuating pin η mounted in the pin hole 215, a first cymbal U that is disposed in the first accommodating hole 217, and a volley in the second accommodating hole 218. Two card engine parts 33. The actuating pin has a dust-collecting head 311 embedded in the counterbore and a rod 200922752 extending into the pin hole 215. The body 312' is recessed in the front of the outer periphery of the shaft 3 12 - a rectangular notch The card slot 313 and the bevel slot 314 connected to the card slot 313 are formed by a bevel portion 3141 and a flat bottom portion 3142. The bevel portion 3141 is laterally connected to the outer periphery of the shaft 312. The flat bottom portion 3142 is adjacent to the latching groove 313 and is formed with a step. The bevel groove 314 is configured to have a stable fixed point position when the first latching member 32 is engaged, and the rear portion of the outer periphery of the shaft 312 is respectively A first positioning groove 315 and a second positioning groove 316 are defined in the recess. The first card 32 has a first block 321 which is inserted into the first receiving hole 217 and an elastic member 322 which is forwardly biased against the first block 321 . The front end of the first block 321 is provided in a rectangular shape. The tooth portion 3211, the soil tooth portion quot" just right, the toothed portion 113 of the wheel head unit 1G makes a snap contact, thereby fixing the ratchet head early and unable to rotate, and the rear end of the first block 321 is provided The double beveled tapered portion 3212 can be slid into the card f groove 313 or the bevel groove 314. The second card 33 has a second block 331 inserted into the second receiving hole 218 and a spring that springs forward against the second block 331. The second block has a front-end card with a pointed shape. The stop portion 33 ι, the locking portion is just embedded in the first or second positioning groove 315 (316). The above is an overview of the shapes and combined spatial patterns of the moving head ratchet wrench of the adjustable angle positioning of the present invention; and then, the action of the present invention and the expected performance can be stated as follows: Reference _ 6' at - In the normal state, the user can press the third pin 3 of the actuating pin η (four), so that the position of the actuating pin 31 is moved toward the first block, and the pin is formed in the first ditch 316, i: the first block 321 The tapered portion can be elastically inserted into the card cylinder 200922752 slot 313, so that the tooth portion 3211 at the front end of the first block 321 can be dislocated from the latch portion 113 of the ratchet head unit 10, and the ratchet head unit is not Under the restriction of the first block 321 , it can be freely adjusted to a predetermined tilt angle. Referring to FIG. 5, when the user confirms that the angle is correct, the shaft 31 of the actuating pin 31 can be pressed to move the position of the actuating pin 3丨 to the right side, and the second block 331 is biased by the spring 332 to be locked. Positioning is formed in the first positioning groove 315. At this time, the tapered portion 3212 of the first block 321 can be wedged into the bevel groove so that the canopy portion 3211 at the end of the first block 321 can be engaged with the ratchet head unit 10 The tooth portion 113 is latched, and the ratchet head unit 1 is restrained by the second card 321 to be stably positioned at the angular position. In summary, the rocking ratchet wrench of the adjustable angle positioning is mainly for solving the problem of the use of the conventional ratchet wrench, and the technical hand 4 of the present invention is mainly used on the actuating pin 3丨. _The pressing head 3η' for hand pressing is convenient and easy for the user to operate. Further, the driving pin η 2 is recessed with the first and second positioning grooves 315 and 316, so that the locking position of the operating pin η can be made. It is quite accurate and will not cause malfunction. Finally, the actuating pin μ is provided with a card 313 and a bevel groove 314, which can accurately position the block-cut: set, so that the card block 321 can be combined with the ratchet head unit card. The card 2 of the tooth portion (1) is extremely stable, so that the present invention has quick and convenient operability, and the effect of adjusting the angle is firmly achieved in the month b.

The pressing head 311 is biased outwardly, thereby providing the driving pin 31 with the ability to keep moving to the right side, so that the user can press the driving pin 31 to adjust the angle freely, and after the driving pin 31 is released, the ratchet head unit 1 can automatically Reverting to the card positioning state is quite fast and convenient to use. However, the above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent changes and modifications made in accordance with the scope of the present invention and the description of the invention.
