The preferred embodiments of the present invention are further described below in conjunction with the accompanying drawings.

As shown in FIG. 1-3, the wrench tool includes a "Z"-shaped wrench body, a first handle 8, a second handle handle 9 and a sleeve 10. The wrench body includes a connecting rod 1 and is disposed at two ends of the connecting rod 1. a first driving portion 1 and a second driving portion 3, wherein the free end of the first driving portion 1 and the free end of the second driving portion 3 are provided with a tool head capable of driving two screws of different specifications, and the first driving portion 1 and The first driving portion 1 is provided with a first mounting groove 6 , and the first driving portion 8 is sleeved in the first mounting groove 6 . The first handle 8 is provided with a cylindrical first cavity. The diameter of the first cavity is smaller than that of the tool head on the first driving portion 2. In daily use, the tool head is generally hexagonal, the first driving of this embodiment The free end of the portion 1 is provided with a hexagonal head 4 for driving a screw. As shown in FIG. 2, the inner hexagonal head 4 is provided with a first adapter sleeve 15, and the first adapter sleeve 15 end can be mounted on the inner hexagon socket. In the first 4, the other end is provided with a disassembly and another The structure of the hexagonal screw of the specification, the first adapter sleeve 15 in this embodiment is an additional structure, and its main function is to change the specification to disassemble and install the screw of different specifications from the hexagonal head 4, or to make other according to the needs of the special component. a tool head of a disassembling screw of a shape, such as an inner five-corner or outer five-corner head, an inner seven-head or outer seven-corner head, a crosshead, an N-corner head, and a second driving portion 3 provided with a second mounting groove 7, second The handle 9 is sleeved in the second mounting groove 7, and the second handle 9 is provided with a cylindrical second cavity. The diameter of the second cavity is smaller than the tool head on the second driving portion, and the second driving in this embodiment The free end of the portion 3 is provided with a hexagonal head 5 for driving a screw, and the outer hexagonal head 5 is provided with a second adapter sleeve 16, and the second adapter sleeve 16 can be provided with an outer hexagonal head 5, and the other end is provided with In the embodiment, the second adapter sleeve 16 is an additional structure, and the main function of the second adapter sleeve 16 is to change the specifications to disassemble and install the screws of different specifications from the outer hexagon head 5, and the sleeve 10 is sleeved. On the connecting rod 1, the sleeve 10 is composed of a first part 11 and a second part 12, as shown in FIG. The first member 11 is provided with a convex structure 13 , and the second component 12 is provided with a card slot structure 14 . As shown in FIG. 5 , when the convex structure 13 and the card slot structure 14 are buckled In time, the convex structure 13 is not easily removed from the card slot structure 14, and the sleeve 10 is reliable in use, and is convenient to install and disassemble. To enhance the bonding effect of the first component and the second component, the first component and the second component are glued by a fixing glue, or the first component and the second component are hooped by a hoop or cuff that is hooped on the surface thereof. When the screw is too tight to be easily disassembled, people are accustomed to holding the first handle 8 or the second handle 9 with one hand, and the other hand is pressed against the connecting rod 1. Since the material of the wrench body is hard, the hand is liable to feel uncomfortable. The connecting rod 1 of the utility model is sleeved on the connecting rod 1 for improving the hand feeling when being gripped, so the sleeve 10 is preferably a soft material.

When the tool head of the free end of the first driving part 2 drives the screw, the user holds the second handle 9. Since the second cavity is cylindrical, it is sleeved in the second mounting groove 7, and the second handle 9 can be opposite to the second The driving part 3 rotates, and feels good when disassembling the screw. Similarly, when the tool head of the free end of the second driving part 3 drives the screw, the user holds the first handle 8, because the first cavity is cylindrical, the sleeve is set. In the first mounting groove 7, the first handle 8 is rotatable relative to the first driving portion 2, and the disassembly and assembly of the screw is convenient. The diameter of the first cavity is smaller than the tool head on the first driving portion 2, and the first handle 8 is not easily slid out from the first mounting groove 6. Similarly, the second handle 9 is not easily slid out of the second mounting groove 7. In order to enhance the hand feeling of the first handle 8 and the second handle 9, the first handle 8 can be installed in the first mounting groove 6 by the method of thermal expansion and contraction, and the second handle is installed in the second installation. A second handle 9 is mounted in the slot 7.

The first driving part 1 and the first handle 8, the second driving part 3 and the second handle 9 can adopt other connecting structures. As shown in FIG. 6, the outer surface of the first driving part 2 is provided with a first ring shape. a groove 17 , the inner wall of the first handle 8 is provided with a first annular protrusion that cooperates with the first annular groove 17 , and when the first handle 8 is sleeved on the first driving portion 2 , when the first annular protrusion is received In the first annular groove 17, the first driving portion 1 can be positioned opposite to the first handle 8. Similarly, the outer surface of the second driving portion 3 is provided with a second annular groove 18, and the inner wall of the second handle 9 is provided. A second annular projection is provided that cooperates with the second annular groove.

The angle α between the first driving portion 1 and the connecting rod 1 is 80° to 120°, and the second driving portion 3 and the connecting rod 1 The angle β between them is 80. To 120. The effective arm length is long during the rotation process, and the energy efficiency is large and labor-saving. The optimum mode is that the angle between the first driving portion 1 and the connecting rod 1 and the angle between the second driving portion 3 and the connecting rod 1 are both 95. The first and second driving portions are inclined with respect to the vertical direction of the connecting rod 1 to reduce the height of the tool head of the free ends of the first driving portion 1 and the second driving portion 3, facilitating the first driving portion 1 or the second driving 3 The free end tool head is placed in the screw head of the screw, and the free end of the first driving portion 1 and the free end of the second driving portion 3 are away from each other, so as to avoid the obstacle to be loosened or locked above the screw to a certain extent. Expand the range of use of this wrench tool.
