Description

Bent action lever for hand tools

The present invention relates to a structure of a bent-shaped action bar for a hand tool, and more particularly, to a special design in which a working end segment and a tool-joined end portion are non-parallel to obtain an optimum extension torque. This facilitates novel inventions of force application and rotational stability.

For example, a general screwdriver (not shown) is used as an example. It is known that one end is a gripping end for the user to hold, and the other end is a so-called "urging rod". The tip of the action (such as a word end or a cross end, etc.) to perform the desired screwing operation on the screw workpiece (not shown). However, the "bend-shaped action rod" discussed in the present invention must first be discussed with an L-shaped hex wrench. First, as shown in the eighth figure, it is the most commonly used conventional L-shaped hex wrench 10 Basically, both ends of the window are visible to the environment and use to rotate the hexagonal screw workpiece, and when we hold the long shaft end 11 to apply force and the short shaft end 12 contacts the working object, Because of the large "force torque", it will have a relatively labor-saving and large rotation torque, and vice versa. Therefore, as shown in the ninth figure, it is a so-called T-type wrench 20, which is designed to achieve a better torque, so that the force applying end 21 and the grip end 22 are vertically designed and held. The end 22 has a length to create a preferred "force moment" to achieve the desired labor savings and better torque.

From the above brief description, we can easily understand that if any hand tool product wants better labor-saving effect and torque strength, its "force moment" at the end of the force is long and short. It is an extremely important key factor.

After that, please refer to the above and refer to the figures shown in the tenth and eleventh figures. It is the most widely used hand tool "bending action rod" 30. As can be seen from the figure, the system includes one An active end section 32 having a working end 31 (which is connected to the driver head 36) for driving the screw workpiece, a bending connecting section 33 and a tool coupling end section 34 for coupling with the force applying tool 35, And the tool is combined with the end section 34 and the working end section 32 in a parallel position state.

Therefore, it is known that the working end section 32 and the tool coupling end section 34 are aligned along a central axis along the center, and according to the basic theory of the moment vector when the rotating force is applied, it can be seen that the extending distance L1 of the two central axes is equivalent to "Triving torque"; as mentioned earlier, the longer the "force torque", the more labor-saving. However, due to its integral design, if the length of the extending distance L1 is to be increased, only the extended connecting portion 33 is extended to enlarge the distance between the working end portion 32 and the tool joining end portion 34, but once designed, The overall volume will also widen and occupy too much space and is not conducive to operational use, but if it is not widened, its torque strength will not meet the actual needs.

In this regard, please refer to the twelfth and thirteenth drawings. In the future, the manufacturer specially designed a shaft joint 37 to make the bending action rod 30 and the force applying tool. The 35-folding into a vertical angle is equivalent to achieving a design feature similar to that of the T-wrench 20, thereby solving the potential disadvantage of the conventional bending-shaped acting rod 30 having insufficient torque. Of course, although this improved design is indeed commendable, it actually has the additional problem of increasing the manufacturing cost and cumbersome assembly procedures. In particular, it is obvious that it is only the connection of the shaft member 37 alone, which will necessarily result in the Insufficient load strength of the shaft joint, and there is great doubt that it is easy to be damaged.

Therefore, the inventor looked at the above facts and relied on his practice of practicing this industry for many years. Experience, active research and development, the invention is available early; therefore, it is mainly focused on not adding additional manufacturing costs and assembly steps, but only a small degree of bending changes, you can get the In order to increase the expected effect of the "force torque", and to enhance its practical value, it is the main purpose of the invention.

Accordingly, the present invention refers to a "bending action lever for a hand tool", which integrally includes an active end portion having a working end for driving a screw workpiece, a bent connecting portion, and a coupling portion. The force tool combined with the tool is combined with the end section, but the main purpose is that the tool is combined with the end section to bend a suitable slope in the direction of the action end section, so that the tool joint end section and the action end section are non-parallel.

In order to further understand the technical means and features of the present invention, the following is a detailed description of the present invention: First, please refer to the first and second figures, which are the structure and use state of a preferred embodiment of the present invention. As shown in the figure, the bent action rod 40 integrally includes an active end portion 42 having an active end 41 for driving a screw workpiece, a bent connecting portion 43 and a coupling with the force applying tool 50. The tool is constructed in conjunction with the end section 44, but primarily such that the tool is joined to the end section 44 in the direction of the active end section 42 and then deflected to a suitable slope so that the tool joint end section 44 and the active end section 42 are not The parallel state is its characteristic.

By means of the special design of the above-mentioned components, it is known that the extending distance L2 of the two central axes is far wider than that of the conventional products, and the working end section 42 and the tool coupling end section 44 are aligned along the center axis. That is, it is equivalent to having a long "force moment", and can achieve the positive purpose of achieving the expected labor saving and generating a large torque, and at the same time not detracting from the overall load strength, especially in the actual use operation, It will be more helpful in the various steps of the initial loosening of the screw workpiece, the rapid rotation in the middle and the final tightening force, without the need of other hand tools.

It has been confirmed by actual test results that the bending angle of the aforementioned tool in combination with the end section 44 is preferably 5° to 60°.

Of course, the present invention can be made into several preferred embodiments to meet all of the needs of use, such as the active end 41 shown in the first figure for plugging the driver head 36, and the third and fourth. As shown in the figure, the latching assembly 60 is attached to the working end 41, and the driver's head 36 can be surely inserted to prevent unintended falling off condition, but the latching assembly 60 is a hand tool product. The used items in the book are well known to the public and are not the characteristics of the present invention. Therefore, the creator will not repeat them. I would like to ask for inspection.

Furthermore, in the embodiment shown in the fourth figure, the tool-binding end section 44 is mainly formed in a polygonal shape so as to be a plug-in shaft and can be connected to a general sleeve type connector (not shown). In addition, the fifth, sixth, and seventh figures show that the working end 41 is directly formed into a cross-shaped body, a one-shaped body and a hexagonal wrench body, and the cymbal can be directly used to rotate the same type of body. Screw-like workpieces.

Looking at the above, the present invention is not only a high-level ideological creation obtained by utilizing the natural law, but also intensive in the printing industry technology and application categories, in addition to not being found in similar articles and related publications in the market, it has already possessed The practical value and positive benefits of novelty and progress are consistent with the requirements for patent applications, and should be protected by the patent law.
