Description of the new type: [The creation of the new type of technology belongs to a crutch, especially an improved and more material-saving crutch. [The prior art is shown in the fourth figure. The conventional crutch includes the main bracket (5 〇), a hollow casing (60) and a telescopic rod (70), the wooden main bracket (50) includes two parallel rods, and the two ends of the casing (60) are fixed at the end of the main bracket (50) And located between two parallel rods, a grip 2 (5 1) is provided between the two parallel rods of the main bracket (50) near the sleeve (60), and the grip (5 1) is used for holding by human hands One end of the telescopic rod (70) is inserted into the casing (60), and an adjusting device is provided between the casing (60) and the telescopic rod (70) to adjust the telescopic rod (70). The length inside the casing (60) determines the overall height of the crutch. Since both ends of the casing (20) are fixed to the main bracket (50), the length of the main bracket (the end of the casing and the casing (60)) The same. If the user uses the crutches vertically, that is, the crutches are perpendicular to the ground, and the force exerted by the users and the ground reaction The stress of the fork is mainly related to the telescopic rod (^ ^). The bearing fork's stress is only related to the θ of the telescopic rod (70). If the user has different terrain or use conditions, the crutch ^ is formed between the faces-less than 45 In this case, the point where the telescopic rod (70) meets the surface is used as the fulcrum. The force received by the crutch will form a moment around the crutch. 'Because the forces are the same', the farther away from the ground the arm is, the A, then λ, the greater the moment, the maximum bending moment is at the midpoint between the handlebar (51) and the bottom of the telescopic rod (7uang M270809). The greater the moment, the greater the breaking mechanism. From this perspective 'The end of the main support (50) and the casing (60) are fixed at each other' is not the key point of the damage, so the end of the main support (0) and the casing (60) have the same length. In view of: [new content] In view of the shortcomings of the conventional practice, the original A + to the department will improve the crutches to reduce the waste of materials. In order to achieve the above-mentioned creative purpose, the technical methods used in this creation + are known at first: Lu also designed a modified crutch, which included a main branch with two carcasses. 'The two rod bodies are parallel to each other and have a fixed gap. One end of the two rod bodies is bent inward to reduce the distance between the two rod bodies. The rod body forms a fixed part there. The other side of the body is provided with a shoulder support and a grip. It is fixed between the two rods. The casing is equipped with a telescopic rod at the end. The telescopic rod is provided with an adjustment device to adjust the length of the telescopic rod inserted in the casing. The improvement is that the other end of the sleeve is The combination section is located between the fixing parts formed by the two rod bodies. The combination section is fixed at two points on the fixing parts of the two parallel rod bodies of the main support. Because the user's force on the whole crutch is similar to $, The user will use the stick at an angle, that is, when the stick and the ground form an angle of -45 degrees, the farther the point on the cane from the ground, the larger the force arm will be. Because the force is the same, the farther away from the ground is the moment The bigger the chance of breaking is, so reducing the length of the ends of the two parallel rods will not affect the overall force. 'This creation cleverly strengthens and avoids the maximum bending moment failure point, so it can not only be fixed by this. Cannula, and can reduce the length of the main frame To achieve the purpose of reducing the waste of M270809 materials. [Embodiment] Please refer to the first figure, the crutch of this creation includes a main support (work), a set of tubes (20), a telescopic rod (30), and an adjustment device (40). Please refer to the first and the first figures, the aforementioned main bracket (10) includes two rod bodies (1 0 1), a shoulder support (1 1), several fixing holes (work 2) (121), and a grip (13) and a fixed seat, the two rod bodies (1 0 1) are maintained at a fixed distance parallel to each other, one end of the two rod bodies (i 〇 丄) is formed in a curved shape to reduce the distance, and the rod body (1 〇) should be The fixing part (15) is fixed, the shoulder support (11) is fixed on the other end of the two rod bodies (101) to provide a clamping and abutting place for the user, and the fixing holes (i 2) (ι 2 1) are opposite to each other. Is provided on two rod bodies (丄 〇 丄), where the array fixing holes (1 2) are provided at the middle of the two rod bodies (ii), and two sets of fixing holes (1 2 1) are provided on the two rod bodies (丄〇 丄) On the fixing part (丄 5), the grip (13) is fixed at the middle part between the two rod bodies (1 + dry k 丄 υ 1), with the fixing hole (1 2) j at the middle part. _Fix it with the fixing piece (丄 3 丄), and match the height of the user Wang Wang E —] body N and arm length, you can fix the grip (工 3) at any fixed position in the middle section (1 2) to facilitate user's holding Fixing base (1 4) ώ < Shang J ί two and each recess so with respect to a two member (1〇1), the holder (14) is provided with a central - perforations.

One end of the aforementioned telescopic rod (30) is sleeved with a foot pad (Sichuan, for increasing power: the telescopic rod (30)) and the ground. The contact area, preventing sliding, and increasing the stability of the extension (30) when standing upright on the ground, the other end of the telescopic rod (30) is provided with a set of opposite through holes (3 2). The withering device (4) 0) is installed in the telescopic rod (30), the length of the telescopic rod (30) penetrating in the sleeve (20) is adjusted, and the overall height of the crutch is adjusted by the height of the two crutches. / 41) 'Bouncing the moon " 1) The telescopic rod ⑴) to work outside ends 9) each have molded - within the circle can be reduced star New Zealand 2).
