DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to a wrench, and more particularly to an L-shaped wrench structure. [Prior Art] Referring to FIG. 1 ' is a perspective view of a commonly used L-type wrench 10, the L-shaped wrench is formed with a long grip portion u, a short grip portion 12, and a long and short grip portion. 1 and 12 f-curves 13 , and the long and short grip segments 11 11 end each have a star-shaped driving portion 14 , and the long holding portion 11 or the short holding portion according to space requirements The driving part u of 12 is inserted into the corresponding locking and unloading member (not shown), and the sawing and unloading operation is carried out. However, the l-type wrench (7) still has defects to be immediately improved in practical use: The long grip section u, the short grip section 12, the curved section 13 and the cross section of each of the driving parts 14 are all the same, and the L-shaped wrench 1〇 is formed by a pair of strip-shaped metal wires. Forming the long grip section spring U, the short grip section 12, and the curved section 13, and the f-curve processing causes the structural structure of the L-shaped panel to be broken, that is, the structural strength of the f-curved section 13 Lower than the structural strength of the long and short grip segments u, 12, therefore, when the l-type wrench 10 is in the process of picking up the dough for the face towel, the required lock release ^ ^ ^ Greater than the wrench 10 when this party bearing torque, it will be deformed in the curved sections, severe cases will break. First, due to the conventional L-type wrench 10, the long and short gripping sections 1 and 12 are in a cylindrical shape. Therefore, when the gripping force is applied, the hand is easily slipped. 201213054 is taken off the long and short. Holding the segments n, 12 causes inconvenience in applying force. According to this, how to close the issue of L-hands, which can solve the above-mentioned defects, is the motive of the invention.

With regard to this issue, the above-mentioned objectives, the techniques, means and other efficacies that have been made are described in detail in conjunction with the drawings. [Embodiment] Referring to Figures 2 to 5, a type 1 wrench, and provided by the first embodiment of the present invention. The structure is mainly composed of a first drive unit 2 and a second drive unit, and a first grip section 30, a curved section 40 and a second grip section 50 of the same cross section, wherein: § grip 4 Further 30' has a rectangular cross section, and the first holding section 3G includes a first inner surface 3b opposite to the first outer surface 32 of the first inner surface 31, and a first inner portion and an outer outer surface 3. a first side 33 of the 32 and a second eye a 7 " q λ a side 34 connecting the first inner and outer 3 and 32 opposite to the first side 33, wherein the first and second sides 33 The distance m between 2012 and 201413054 is greater than the distance _ between the first inner and outer outer surfaces 32, and the vertical direction is between the inner inner and outer outer surfaces 31 and 32. The curved section 40 has a rectangular cross section, and the curved section 4 is formed at the _ end of the first holding section 3Q, and is folded at an angle toward the first direction ' 'the f section 40 The inner curved surface 41 connecting the first inner surface 31, the outer curved surface 42 connecting the first outer surface 32, the first curved surface 43 connecting the first side surface 33, and the second connecting the second side surface 34 Surface 44. The second gripping section 50' has a rectangular cross section, and the second gripping section 50 is formed at one end of the curved section 40 and extends to form the second gripping section with the first direction. 50 includes a second inner surface 51 connecting the inner curved surface 41, a second outer surface 52 connecting the outer arc φ 42 , a third side surface 53 connecting the first curved surface 43 , and a second connecting the second curved surface 44 Four sides%. The first driving portion 2 is formed on the first holding portion 30 and extends in a second direction γ perpendicular to the first direction X. In the embodiment, the first driving portion 21 is star-shaped. For example, it can be hexagonal as shown in Figure 6 but not limited to these two types. The first driving portion 21 is located between the first inner and outer surfaces 3 and 32 of the first holding portion 30, and is also located between the first and second side surfaces 33 and 34 and the horizontal of the first driving portion 21 The maximum distance D3 of the cross section is smaller than the distance D1 between the first and second side % and % of the first driving portion 21. The second driving portion 22 is formed in the second holding portion Μ and is extended and formed in the first direction. In the embodiment, the second driving portion 22 is exemplified by the 201213054 star shape. Figure 6 shows the state as a limit. The first driving portion 22 is located in the second outer portion 51, 52$ρθ, and the second inner portion, and the first portion is also located in the third and fourth portions. Between the side faces 53, 54, the maximum distance driving portion of the cross section of the _ portion 22 is the distance between the third and fourth side faces 53, 54: in the second configuration: the first embodiment of the present invention The structure of each main component and its = when the L-type wrench is locked and unloaded through the first medium moving portion 21 or the second driving portion, due to the first and second holding segments 3(), 5q and bending The cross section of the segment 40 is larger than the cross section of the first and second driving portions 2i, 22, that is, the distance between the first and second side faces 33, 34 of the first grip portion 30, such as the second grip. The distance between the third and fourth side faces 53 and 54 of the holding portion 5G and the distance between the first and second curved surfaces 43 and 44 of the f curved portion 40 are larger than the first driving portion 21 or the second driving portion. The maximum distance of the cross section of 22, and the distance w between the first and second sides 33, 34, the distance D5 between the third and fourth sides 53, 54 and the first and second curved surfaces 43, 44 Twisted distance The direction of the force applied during the pulling, therefore, the curved portion 4 〇 has a stronger structural strength to resist the torsion generated when the bending portion and the driving portion are the same in cross section. The purpose of the [type wrench to reduce deformation or breakage of the bent portion during the locking and unloading process is achieved. In addition, the first and second sides 33, 34 are connected between the first inner and outer surfaces 31, 32 of the first holding portion 3, and the cross section of the first holding portion 30201213054 is - The third and fourth sides 53 and % are connected between the second inner surface and the outer surface 51, 52 of the second holding portion 50, and the cross section of the second holding portion 5G is - The rectangular cross section, therefore, the type of wrench of the present invention is a columnar structure, and the hand grips the first holding section 30 or the second holding section 40 stably when the holding force is applied. In order to achieve a lowering of the grip of the L-wrench in the process of locking the unloading process causes the slippery to occur.
