New description: [New technical field] This creation is about the improvement of a wrench handle structure, especially the grip of the wrench is composed of a flexible tube and an elastic tube. The structure is elastic and bendable. - Folding, 忒 wrench can be extended into the structure of the wrench used in the narrow or tortuous work space. [Prior Art] • As previously known, the structure of a wrench that can be swung from the rear end of the wrench is used, as in the U.S. Patent No. 4 6 9 〇28, the wrench of the patent, the structure of which is The end of the wrench grip controls 3 6 degrees of rotation to rotate the pinion gear of the α卩 in the handle, and the pinion gear meshes with the large gear fixed by the rotating member, so that the large gear can be linked and rotated. The rotating member is convexly provided with a sleeve end, and the sleeve end can fit the sleeve to rotate the lock screw. " The advantages of the patents mentioned above are: · When the working space is limited and the helmet is backhand, the user can rotate the pinion clock at the end of the grip of the wrench and interlock the large return wheel and the rotating part to act. It can solve the space problem: 'But the wrench used in this utility has a fixed shape at the grip, which is difficult to use when it is on the eve. This is the missing. In view of the experience of the above-mentioned patents and related industries, there is finally a world. The structure, the creator borrowed many years to engage in the creation of the wrench structure of the product M340899 [new content], and the body is sturdy, this creation is about a wrench handle to include: the drive head, the m-th structure improvement, a main tube, wherein: the driving head system comprises: a = rotation = tube, the body is provided with a - accommodating groove, the body handle is provided with a first tooth portion, and the first gear system is fixed on Turn: piece: the outer riding system is set in the hole of the body, the second gear front end rides d part 'the second tooth part is merging with the first tooth part;-: Γί: two end system And the second _ set =::, the flat h is wrapped on the outer circumference of the flexible tube (4) on the body, and the other end of the flexible tube is exposed to the f-fold of the elastic tube external force, the elastic tube can be Self-response ^ Straight management In order to enable your review board to further understand and agree with the purpose of this creation, special science, and good fortune, the following is more important than the workmanship: Niu Pingyi 1 soil only example sub-pattern Explanation [Embodiment] First of all, please refer to the first figure, which is the three-dimensional exploded view of the creation, and the structure of the wrench is changed.
