Description of the invention: [Technical field to which the invention pertains] In particular, it relates to a wrench which can quickly change the driving head of the invention and the bending tool. [Prior Art], - People, master t's wrench can be divided into: double open wrench, double plum wrench, = fit wrench, ratchet wrench, socket wrench, and adjustable wrench, etc., although there is - part Wei is Common, but still have its own special use. Thanks to the complex. The wrench can only rotate a single size screw (or nut), because H generally has a number of sewed ten-way wrenches (or two double-shaped wrenches, ratchet wrenches), and the two drive ends are rive-ended ) With the handle, most of them are integrally formed, and the drive ends are not interchangeable. The general sleeve set has a ratchet wrench and a plurality of sleeves of different sizes I5, and the σ2 ratchet wrench has a square drive end, which can be replaced with various π-size sleeves for rotation. Different sizes of bolts (or nuts), but if you want to adjust the space of the screw (for example, the narrower the engine's screw space), you must make different angles and avoid the space limit to drive. In order to achieve the above purposes, most of the wrench drive end and the sleeve, plus a 20 joint _ _ eal joint, operation is not easy; although it can be directly inserted into the million (Universd sockets), but due to high production costs, almost No one took it, but because the sleeve is closed, it is impossible to use the hexagonal joint that is connected to the pipe. Use the adjustable wrench to adjust the activity display to obtain the required distance between the fixed cymbal and the activity rhyme 4 1271275. The bolt (or nut) can be rotated within a predetermined size range. The driver's wrench can be bent. Or a wrench that can be adjusted, or can be fixed at an angle, such as, for example, U.S. Patent Nos. D506,373S, 5,581,959, 5,768,960, 6,295,898, 6,000,302, and 5,199,335. Patent No. 4,711,145, and earlier publication No. 20 (H/0144219, and National Patent Publication No. 483, 371, etc. These drive heads may be bent, adjusted, or fixed at a certain Angle, but can not be quickly replaced. 1 〇 In the conventional wrench, the driver can replace the wrench, such as: National Patent Announcement 苐 482, 064 'di brother one figure: Although the driver can be replaced, but the drive head is not in Z The direction of the axis is the bending angle. Another example is: National Patent Publication No. 497,526: "The sleeve part of the head is formed into a circular arc shape, ... has a long arc-shaped slot, so that a combined screw can be worn. in. ·』, not only into 15 咼, when replacing the driver's head, it can't be replaced quickly, and when the force is large, the screw rod will have an angle idling in the long arc-shaped slot. Another example is: National Patent Announcement No. UJ25 It is shown that the structure of the replaceable drive head and the structure which can be bent at the z-axis direction are separate, and the cost is high, and the assembly takes time and the like. 20 [Summary of the Invention] The main object of the present invention is Providing a wrench that can quickly change the drive head and can be angled, which not only can quickly change the drive head, but also can be bent to change the angle. 1271275
