TWI258403B - Anti-skidding structure for a socket wrench - Google Patents

Abstract

This invention provides an anti-skidding structure for a socket wrench (4), including: a wrench body and an urging device, wherein the wrench body is provided at a driving portion with a slit, and an urging hole at its center for receiving the urging device. In use, when pressure is applied to cause the urging device to urge against the driving portion, the outer edge of the driving portion would therefore expand such that it is able to urge against a Hex-screw that has been rubbed off such that the screw can still be wrenched by preventing skidding.

Description

1258403 V. INSTRUCTION DESCRIPTION (1) [Technical Field] The present invention relates to a structure of a hexagonal wrench anti-slip device, and more particularly to a wrench that can be used for preventing slipping of a hexagon socket screw. [Prior Art]

Press, as far as we know, the screws that are generally used under long-term use will have a rounding phenomenon. The screws after the rounding will make the wrench difficult to pull, which will make it more difficult to work with the screw. The screw is removed again in a destructive manner, and this method will cause damage to the workpiece itself. Therefore, this method is the next strategy. Therefore, the industry has a series of wrenches for rounding hexagonal screws, which has a solution to the rounded hexagonal screws; however, the above improvements are only for the invention of the hexagonal screws. However, the solution to the hexagonal screw is far from complete, and there is no such thing as an invention that can effectively solve the rounded hexagonal screw.

For this, the difficulty lies in the traditional hex wrench (please refer to the seventh figure), which is a simple L-shaped type, and its driving head is designed for different sizes of hexagonal solids, and its structural design is not The open-end wrench is fastened to the hex head by the clamping portion at both ends, and there is no space limitation. Therefore, the geometrical change of the clamping portion at both ends and the change of the calculation angle can be arbitrarily changed. To solve the problem of the hexagonal screw used for rounding, the first thing to face is the problem of the most difficult space limitation, and the reason why the industry has been unable to break through is also here. As described above, the present inventors have not considered the existence of the above-mentioned hex wrench.

Where I think, I feel that I have the experience to study and design this creation. The need for improvement is to improve and, after a long period of time, make it more practical to engage in the design experiment and modification of this kind of product design system. 'And to promote the progress of the industry to S is to provide a way to break the past can not effectively solve the ί = 2? angle screw is not easy to pull the stomach, in the normal use: the brakes can be easily adjusted Hexagonal screw; its main system;: The driving part of τρ螌 is provided with a groove, and then the center is provided with a top 掣Chen 骢 邱 邱 * 装置 装置 装置 装置 装置 装置 装置 , , , , , , , , , , , , , , , , , , , Therefore, the outer edge of the driving part is enlarged, and it can resist the purpose of preventing the slipping and the inability to pull the hexagonal screw which has been rounded. This is a way of breaking the traditional thinking, and often The mind of the invention is limited to the use of the existing space, and further changed to "creating its own space" to break the dilemma that cannot be improved. Therefore, after the splitting groove is formed, the wrench system is sufficient for t to change, and the shape of the body can also be used as a small change to the body, and then deformed by the body to resist the rounding. Hexagonal wire 故 故 故 = = to prevent slipping when the pull occurs. The ultimate goal of the present invention is to utilize the design method to achieve the purpose of directly preventing the hex wrench from slipping without the need of manual T-setting, whether it is used in a normal hexagon socket screw or a hexagonal hexagon. The silk yarns are all fastened to the hexagonal screws through the invention, and can be used for the purpose of use.

1258403 V. INSTRUCTIONS (4) The shape change makes the external shape of the body change with the screw inside the circle, and further can pull the hexagonal screw that has been rounded. When using, please match the state before use, as shown in the third and fourth figures. As shown in the third figure, the top piece (2 2 ) is slightly exposed to the top surface of the sectioning groove (1 2 ). The hexagonal wrench has a regular hexagonal shape, which is beneficial to the normal normal hexagonal screw. When there is a hexagonal screw with rounding, you can refer to the figure shown in the fourth figure. When the screw is pressed, the top piece (2 2 ) will be forced into the top hole (1 3 ), and the driving part (1 1 ) will expand outward, and the tight card will be inside the circle. The end of the hex screw can prevent the hex wrench from slipping and can not resist the hexagonal hex screw; when it is used, the elastic member (2 3 ) will push the top member (2 2 ) outward to make the driving part (1 1 ) Re-returning its status to match the next use is the best design. Please refer to the fifth and sixth figures as a second preferred embodiment of the present invention, wherein the top device (20) can be a top member (2 2 > ) and an elastic member ( 2 3 >), and the elastic member (2 3 > ) is fixed at one end to the top member (22 >), and the other end is fixed in the top pupil (13) to achieve the same effect, and The processing of the screw hole (14) is omitted, and the top piece (2 2 >) does not need to increase the processing of the perforation (2 2 1 ) and the layer (2 2 2 ), and the same method of use can be used. To achieve the purpose of preventing the hex wrench from slipping, it is also designed for industrial use. In summary, the hexagonal wrench anti-slip device structure (four) of the present invention is in the knot
