Abstract

This invention is to provide a T-shape wrench for overcoming the problems of conventional T-shape wrenches that horizontal displacement and angle adjustment cannot be integrated. The T-shape wrench of this invention has a body with a connection part, the body having a vertically indented slot which separates the body into two side walls between which an axle is disposed. The axle has a hole relative to the slot for pivoting a long rotary rod with two ends each of which is sleeved to a C-shape hook for securing the rotary rod. The rotary rod can be separated equally into two parts or extended toward one side. The axle can be adjusted to provide two isometric sides or one extending side so as to adjust the obliqueness of the rotary rod with the rotatable axle, such that the T-shape wrench can be shifted vertically while the angle can still be adjusted, largely increasing the utility of the T-shape wrench.

The force arm (as indicated by the dashed line), f隹, the conventional case of the rotary rod 1 2 can not be used when it encounters an obstacle in its rotation, but must use the second type as shown in Figure 2. T-shaped wrench 1 4, the second conventional τ-type plate: the 14-series also has a body 15, the body 15 is formed with a recessed groove ί from the upper end face downward, and the missing groove 16 Inserting a rotating rod 18, a shaft pin i 7 is simultaneously pivoted through the body 1 5 side walls 丄 5 丄, 1 5 2, the rotating rod 18, the shaft 丄 8 axis is pivoted in the vacant groove 26 The tilt angle can be adjusted, and the bottom end of the body 15 is formed and reduced. The rectangular assembly portion 9 9 can be engaged with the sleeves 3 各种 of various sizes, and the first type of white matter can be used. The function of adjusting the tilting angle can solve the problem that the obstacle is encountered when the rotation is performed. However, when the adjusting rod 8 8 is to be extended to the side of the side 2 200848219 and the maximum arm is extended, the shaft bolt is received. The limit cannot adjust the displacement; Therefore, the first and second conventional cases each have their own advantages and disadvantages, and their shortcomings need to be improved. SUMMARY OF THE INVENTION ^ Based on the above-mentioned problems of the conventional T-shaped wrench, the present inventors have made great efforts in the interest of the people, concentrating on research, constantly designing and improving, and making sample tests, and repeating tests, and then improving them. The present invention, which finally achieves the following object of the invention, was born. That is, the object of the present invention is to enable the T-shaped wrench's rotating rod to be adjusted horizontally or horizontally at the same time or separately, so that the use of the T-shaped wrench is more convenient. In order to achieve the above object, the present invention is characterized in that it comprises a body having a joint portion and a groove, a shaft body disposed in the body of the body, and a pivoting body and reciprocally displaceable The rotating rod, the rotating rod and the body missing groove are in the same direction, and the rotating rod and the shaft system are in the staggered direction. [Embodiment] In order to make the present invention more familiar with the present invention, the following is a detailed description of the preferred embodiment, and the detailed description is as follows: (only the embodiment is only for the purpose of explanation, The implementation of the present invention in the future is not limited thereto, and any improvement by the present invention is subject to the invention. As shown in FIG. 2 of the drawing, the T-shaped wrench 2 of the present embodiment comprises a body 2 1 , a shaft body 2 2 and a rotating rod 2 3 ; the body 2 1 is located from the middle of the upper end surface thereof. The first and second side walls 2 1 2 and the second side wall 2 1 3 are respectively provided with a side wall formed on the bottom of the main body 2 1 . Opposite the perforations 2 1 4, 2 1 5, the bottom of the body 2 1 is provided with a reduced assembly portion 2 1 6 , the assembly portion 2 16 is capable of engaging the sleeves 3 of various sizes or other various extension functions. Tool shaft (not shown); the shaft body 2 2 is a cylinder, and the shaft body is provided with a through hole 2 2 1 , and the shaft body 2 2 is pivoted to the first and second side walls 2 1 of the body 2 1 2, 2 1 3 perforations 2 1 4, 2 1 5, and the body 2 1 is pivoted and can be rotated; the rotating rod 2 3 is a long cylinder, and both ends are provided with a ring groove 2 3 1 Each ring groove 2 3 1 can be sleeved with a c-type buckle 2 4 , and the screw rod 2 3 is at one end of the C-shaped buckle 2 4 is to be rotated 2 2 through the shaft 2 2 perforation 2 2 1 After the cover, the two buckles are slightly larger than the perforations 2 2 1, so that the rotary lever 23 will not be self-axial. 22 off. Referring to FIG. 4 to FIG. 6 again, when the T-shaped wrench 20 of the embodiment is used, the assembly portion 2 16 can be embedded in the slot 3 1 of the sleeve 3, and then has a bore. The driving part 3 2 aligns the workpiece 4; [the screw end 40 of the upper part, and then rotates the rotating rod 2 3 to work on the screw, and the rotating rod 2 3 can adjust the arm located on both sides of the body 21 as needed The same length or only one side extends to the longest arm or the angle of inclination of the screw 2 3 can be adjusted simultaneously to avoid obstacles. Referring to FIG. 7 again, in order to prevent the rotary rod 2 3 from being autonomously displaced by the weight in the shaft 2 2 hole 2 2 1 , the inner wall of the shaft 2 2 is facing the shaft body. A counterbore 2 2 2 is drilled in the axial bottom surface, and the sinking 200848219 hole 2 2 2 is sequentially inserted into the elastic crystal 2 2 3 and a steel ball 2 2 4, and the steel ball 2 2 4 is caused by the elastic yellow 2 2 3 Pushing the top, the blame is against the rotating rod 2 3, so that the rotating rod 2 3 can be displaced when the external force is applied, and does not make an autonomous displacement. Referring to FIG. 8 , in order to prevent the shaft body 2 2 from being detached from the body 2, the first or second side wall 2 i 2, 2 1 3 of the body has a perforation 2 and 2 1 5 inner ring wall surface. A ring groove 2丄7 is provided (the ring groove 2 17 in the embodiment is disposed on the second side wall 2 1 3 ), and a ring-shaped ring 2 5 is placed in the ring groove 2 17 The elastic ring 25 is elastic and (1 is deformable, and the outer ring surface of the shaft body 2 2 is opposite to the annular groove 2 17 of the second side wall 2 1 3 , and a ring groove 2 2 5 is also provided. When the shaft body 2 2 is pivoted between the two teeth 2 1 5 and 2 1 4, the outer portion 2 5 1 of the spring ring 2 5 is clamped to the second side wall 2 1 3 groove 2 1 7 In the middle, the constricted portion 2 5 2 of the elastic ring 25 is clamped in the groove 225 of the shaft body 2 2 so that the shaft body 2 2 and the main body 2 1 do not disengage without external force. In order to prevent the shaft body 2 2 from being detached from the body 2 1 , another embodiment of the present invention is applied to the first or second side wall 2 1 2 , 2 1 3 perforations 2 i 4 of the body. A groove 218 is formed in the inner wall of the inner ring of 2 1 5 (the groove 218 of the embodiment is disposed on the second side wall 2 1 3 ), and the shaft body 2 2 is outside. With respect to the groove 218 of the through hole 215, a radial counterbore 2 2 6 is provided, and the counterbore 2 2 6 is sequentially placed with a spring 2 27 and a steel ball 2 28, so that the steel ball 228 is pushed by the spring 227 When it is topped, the steel ball 2 2 8 can be constantly in the groove 2 1 8 of the perforation 2 1 5 , so that the shaft body 2 2 and the body 2 1 do not separate from each other without external force 0 200848219 As described above, the present invention has practical and progressive nature, and invites people to inspect domestic and foreign literatures, and does not find the same or similar, and = this application meets the requirements of the invention in the patent law, and submits an application in accordance with the law.么月诚 [Simple diagram of the figure] Figure 1 is a three-dimensional schematic diagram of the first conventional T-shaped wrench.
