The ground is fixed by applying force to the ball head a. However, after all, the spring can exert a limited force, even if the ferrule has been fixed after the mosquito test, it is expected to change the adjusted if it is subjected to other external force side. Good angle, and the angle of rotation of the sphere is directly limited by the cone of the fan-shaped hole. == The universal joint structure shown in the figure is only suitable for the force of very small work, or the instrument is used, and the angle The scope of adjustment is small. [Summary of the Invention] The technical problem to be solved is smaller. The face of this hair is due to the shortness adjustment of the traditional cardan shaft structure and the lack of fixed strength after adjustment. 1259245 "Technical means for solving the problem" The present invention utilizes the following technical hand In order to achieve the above objectives·· The creation of the cardan shaft structure mainly includes - the body, the two spheres, the bolt and the 1 cap; the α hai spheres are respectively coupled to the two ends of the body, wherein the sphere can be combined with the body to be 1, In addition, the sphere is separated from the body; or both spheres are integrally formed with the body; the body is provided with a through-hole that leads to the ends of the sphere, and the side walls of the two spheres are provided with a plurality of cuts, and the average is divided into fine, and The _ _ end of the _ _ end is provided with a tapered socket, the bolt is placed in the center hole of the ball separated from the main body, and the other end of the ball locks the cap, the two spheroids hold the tree and hold the tree, by means of Rotating the bolt head of the bolt, the elm chest is whistling, and when the ball is swollen, it will be fixed with the W _ rotation. When the ball is restored, the ball and the inner wall of the clip are not supported. _ holding the tree to adjust the angle., "Effects on the prior art" Compared with the conventional universal joint device, the present invention mainly utilizes the universal joint shaft structure and the bolt and the __ to expand or restore the sphere, thereby making the desire = movement element 'offset in angle; by this The single structure not only solves the problem that the universal joint is adjusted in a small angle range and the fixing is not accurate, but also achieves the purpose of reducing cost and maintenance. [Embodiment] The following is an example of the implementation of the creation. - After the description of the step, it is better to see 6 1259245. Please refer to the first and second figures, which shows an exploded view of the present embodiment. The creation includes - the body is provided with a sphere m at each end thereof, wherein One k L can be solidified & at the "end" of the body i, and the other - the sphere 2 is separated from the body 1; the center of the side body 1 is provided with a through hole n and penetrates the sphere 12, and the side wall of the sphere 12 is provided with a plurality of through-centers a hole n and a slit 14 at the end thereof, and a socket portion 15 (shown in FIG. 2) is disposed in the center hole of the end of the ball (four). The other end Z of the body is provided with a bump 13 which is provided. It can be square or other corner shape. The further detached sphere 2^ has a recess 22 complementary to the bump 13, and can be connected by the ghost 3' and the recess 422; the bump 13 and the recess 22 can be any other or Multi-corner shape. The side wall of the sphere 2 is provided with a plurality of slits 22 penetrating therethrough, holes and other ends, and a writing portion U is formed in the center hole of the end portion. A bolt 3 is sequentially passed through the center hole of the ball 2, the body 1 and the ball 12, so that the bolt is inserted into the bearing portion 21, and the external thread of the other end of the bolt 3 is locked - the nut 4' and the nut 4 is located in the housing portion 15 of the sphere 12. Please refer to the second figure for the combined structure. (4) In addition to this, 'another embodiment of the present invention can form the two ball limbs 2, 12 and the body} or the sphere 2 separated from the body in the upper paragraph is welded to the body by welding. Together. In order to obtain a flattening effect on the outer surfaces of the spheres 2, 12, the preferred embodiment of the present invention uses a flat head bolt to connect the two spheres 2, 12 and the body i in series, and the screw head is buried 1259245 into the socket portion 21 of the sphere 2. Inside. One end of the nut 4 has a taper like the head of the thread check 3. After the nut 4 is locked to the thread check 3, the nut 4 is buried in the socket portion 15 of the ball, I]. Ugly The fourth picture shows the actual use of this creation. The two spheres 2, 12_ of the present creation are matched with the holder of the holding member 5; the holding member 5 may include two clips X 51 having the curvature of the surface of the corresponding spheres 2, 12, and the two clips η are covered. After the body 2 or 12', the two clips are magically locked by screws (not shown), so that the spheres 2, 2 are expected to be formed in the _-shaped space of the two clips 51; one of the holding elements 5 _ side There is a through hole 52 which is provided with a screw such as a screw scale or a second work == hole! When the bolt 3 is locked, since the bolt head is close to ', the ground*, the bolt head and the nut 4 simultaneously apply pressure to the socket portions 21, 15 of the two spheres 2, 12, μ^α±α η 攸 攸Further, the spherical bodies 2, 12 are expanded in the outer diameter direction, and the opposing members 5, 1 > inner wall surface 'the so that the balls 2, 12 gl can be fixed to the clip η, and the holding element is swung. On the other hand, when the bolt 6 is loosened, the bolt head and the nut 4 are freshly separated, thereby releasing the pressure on the socket of the sphere, and the elasticity of the two spheres 2, 12 and the force 1 itself is restored to the original state 'two spheres and clips at this time There is no or no between the sheets 51, so that the holding member 5 can be rotated to adjust the angle. The attempted person is only a preferred embodiment for explaining the creation of the creation. It is not the same as the second: the creation of any restriction on the creation, so that any modification or change made by the company under the spirit of the essay is Still in the scope of this creative intent. 12592^ [Simple description of the formula] First, Fig. 2 shows the embodiment of the embodiment of the TW-adjustable tightness.
