The second drawing is an exploded perspective view of the first figure. The second figure shows a cross-sectional view of the first end and the second end of the present invention. The fourth drawing is a longitudinal sectional view of the first figure. The fifth figure is a partial enlarged view of the fourth figure. The sixth figure is similar to the fourth figure, showing that the post is moved down to a release position. The seventh figure is a partial top view of the first figure. In May, referring to the first and second figures, the first preferred embodiment of the wrench (1) provided by the present invention has a gripper 2, and the two ends of the handle are connected to each other. (M). Each of the head (U) and the handle (10) is connected to a second end 4 (30) by a first end (20) and can be adjusted in relative angle. The first end (20) can be one end of the handle (12) and the second end (3) can be one end of the head adjacent (14). It will be understood that the first end and the second end are interchangeable such that the second end (20) is the end - end of the head (14) and the second end is the end of the grip (12). The other end of the head (14) is a set of ends (16) 'for the socket nut, the socket end (10) can be an open end or a closed end (b〇x end), the closed end can be It is a polygonal sleeve hole; the closed end may also be a ratchet structure 'with a ratchet; the socket end (10) may also have a - stud (for example, the second icon number of the patent No. 93102729) To insert the sleeve. The socket end is a conventional structure and will not be described. Referring to the third figure, the first end (2〇) has an upper jaw (21) and a lower Ρ Ρ Ρ (22) ′ which are juxtaposed one above the other, and a space (24) is formed between the ones. A first perforation (25) is provided in the upper crotch portion ρ2), and a peripheral wall has a plurality of teeth (26); a through hole (27)' is provided in the crotch portion (22), and corresponds to the perforation (25). A limiting protrusion (28) is disposed on the hole wall of the through hole (27). The first end (30) is provided with a second perforation (32) having a plurality of circumferential walls (four). The second end (10) extends into the space (four) between the two parts ^. The second perforation (32) is located between the first perforation (25) and the through hole (27) and corresponds to each other. Further, in the present embodiment, the bottom edge of the second perforation (32) is not formed with a tooth and is formed as a hole portion (36), but the hole portion (36) is not an essential configuration. - a post (40) having a plurality of teeth (42) on the circumference, and the teeth (42) are only formed on the top surface of the post in this embodiment. The upper teeth (4) can also be made on the top side and the bottom side of the cylinder, which is secretive. The card is disposed in the two perforations (25) (32) and the through hole (27), and the second end (20) of the fourth and fifth figures is combined with the second end (3). The post (40) can be moved up to one of the card-spot positions shown in Figure 5 to the -release position shown in Figure 6. In detail, the peripheral surface of the post is provided with a flange (44)' which is formed by a -c buckle and is fastened to a ring groove (45) provided on the peripheral surface of the post. The outer diameter of the abutting edge (44) is greater than the inner diameter of the second perforation (32) of the second end (3), so that the abutting edge (44) can abut the bottom surface of the perforating hole (32), such as In the five figures, the perforations (25) (32) are not removed when the post is moved up. When the post (4〇) is moved down to the release position of the sixth figure, the collar (28) is abutted by the abutment (44) (or by the bottom wall of the tooth (42) against the flange (28) ), so that the post does not come out. At least one elastic positioning member (46), for example, composed of a spring and a steel ball, is embedded on the bottom side of the post and located below the abutment (44). The elastic positioning member is elastically exposed on the peripheral surface of the post. When in use, please refer to the first and fifth figures. When the post (4〇) is in the clamping position, it penetrates into the first perforation (25) and the second perforation (32). The teeth of the post (42) At the same time, the teeth of the = perforation (25) (32) are engaged, so that the first end (2〇) and the second end (3〇) are engaged and fixed, and cannot be rotated relative to each other. Thus, the nut can be rotated by the head (14) when the grip (12) is pulled. The resilient retaining member (46) of the post (40) abuts against the top surface of the collar (28) to maintain the post in the engaged position. Preferably, the abutment (44) simultaneously abuts against the bottom wall of the second end (30) so that the post does not sway up and down when it is in the engaged position. When the post (40) is pressed down and moved down to the release position of the sixth figure, the post (40) leaves the first perforation (25), at which time the post is only with the second perforation ( 32) The joint is not sprayed with the first perforation (25), and the first end (2〇) and the second end (3〇) are no longer engaged and fixed and form a relatively rotatable state, the head (14) ) With the grip 〇 2), the post (4 〇) can be rotated relative to the center of rotation, as shown by the imaginary line in the seventh figure. After the head (14) is rotated to the desired angular position, the post (4〇) is pressed back to the engaging position of the fifth figure to re-fix the two ends (20) (30). The spring post (40) slides over the flange (28) when the post (40) is moved from the engaged position to the release position or when the release position is reverted to the click position. When the first end and the second end are released from the meshing state of the fifth figure to the released state of the sixth figure, it is only necessary to move the post (40) between the perforations (25) (32) without The handle and the head are relatively displaced. Therefore, the user can release the engagement between the handle and the head by pressing the post (4〇) with the thumb of the hand holding the handle (12), in other words, 1337919 bis The grip state and the head can be locked in one hand, without the convenience of using the pick. Furthermore, the structure of the present invention is simple, accurate, and easy to operate. The above examples are merely illustrative of the invention and not to limit it. In summary, the present invention is the first structure of the same kind of articles, and has the promotion of progressive efficiency, and is in line with the invention patent requirements, and submits an application according to law. The principal members of the praying committee encouraged the beauty of the Chinese people's mines to make a detailed examination and to grant the patent as a prayer.
