Therefore, an objective of the present invention is to provide a multifunctional spanner, which designs angles between driving heads at the two ends and a grab handle at the middle part, and helps a user to further smoothly operate the spanner.
According to one embodiment provided by the present invention, a multifunctional spanner is provided, which comprises a grab handle, a first driving head and a second driving head. The first driving head is integrally connected with one end of the grab handle, an included angle alpha is formed between the driving axis of the first driving head and the central axis of the grab handle, one port of the first driving head is horizontally connected with the grab handle, and an included angle phi is formed between another port of the first driving head and the grab handle. The second driving head is integrally connected with the other end of the grab handle, an included angle beta is formed between the driving axis of the second driving head and the central axis of the grab handle, one port of the second driving head is horizontally connected with the grab handle, an included angle theta is formed between another port of the second driving head and the grab handle, the included angle alpha and the included angle beta are respectively located on different sides of the central axis of the grab handle, the second driving head is hollow and cylindrical, and the inner wall of the second driving head is provided with multiple tooth parts.
According to the spanner, at least one end of the grab handle is provided with multiple embossed patterns.
According to the spanner, the included angle alpha between the driving axis of the first driving head and the central axis of the grab handle is larger than 7 degrees and smaller than 45 degrees, the included angle beta between the driving axis of the second driving head and the central axis of the grab handle is larger than 7 degrees and smaller than 45 degrees, the included angle theta between the port of the second driving head and the grab handle is larger than 0 degree and smaller than 25 degrees, and the included angle phi between the port of the first driving head and the grab handle is larger than 0 degree and smaller than 25 degrees.
It can be known that the driving axis of the first driving head and the driving axis of the second driving head respectively deviate from the two sides of the central axis of the grab handle, thereby improving the strength of a connection part between the grab handle and the first driving head and the strength of a connection part between the grab handle and the second driving head, increasing the torsional moments of the two connection parts, and improving the strength of the spanner under the external force.

Description of Embodiments FIG. 1 is a stereoscopic schematic diagram of a multifunctional spanner according to an embodiment of the present invention. The multifunctional spanner 100 comprises a grab handle 110, a first driving head 120 and a second driving head 130. The first driving head 120 and the second driving head 130 are respectively and integrally connected with the two ends of the grab handle 110, and arrangement of each component and their relationships refer to the following description and accompanying drawings. FIG. 2 is a front view of the spanner according to the embodiment in FIG. 1. An included angle alpha is formed between the central axis of the grab handle 110 and the driving axis of the first driving head 120, wherein 7 degrees < alpha < 45 degrees. The driving axis of the first driving head 120 deviates from the central axis of the grab handle 110, thereby achieving a labor saving effect. Due to the included angle between the first driving head 120 and the grab handle 110, a user can operate the spanner by using a comfortable and convenient holding manner.
Similarly, an included angle beta is formed between the central axis of the grab handle 110 and the driving axis of the second driving head 130, wherein 7 degrees < beta < 45 degrees. Therefore, when the user operates the second driving head 130 on a component to be driven, effects of saving labor and facilitating holding also can be achieved. Especially, the included angle alpha and the included angle beta are respectively located on different sides of the central axis of the grab handle 110.
Furthermore, at least one of the two ends, connected with the first driving head 120 and the second driving head 130, of the grab handle 110 can be provided with multiple embossed patterns 111. As shown in FIG. 2, in the embodiment, the embossed patterns 111 can be arranged at the two ends of the grab handle 110. The embossed patterns 111 have an anti-slip effect, and can help the user to more smoothly operate the spanner. FIG. 3 is a side view of the multifunctional spanner according to the embodiment in FIG. 1. A port 121 of the first driving head 120 and a port 131 of the second driving head 130 can be horizontally connected with the grab handle 110. Therefore, when the spanner 100 is operated at the edge of a device, the spanner 100 can be closely clung to the surface of the device, and the first driving head 120 and the second driving head 130 can tightly clamp or hold on the component to be driven, thereby improving the smoothness of the span in use.
Furthermore, an included angle phi is formed between another port 122 of the first driving head 120 and the grab handle 110, wherein 0 degree < phi < 25 degrees. Different from the horizontal connection of the port 121 and the grab handle 110, the included angle is formed between the port 122 and the grab handle 110, so that the spanner can be operated on a device with an unsmooth surface or relatively more peripheral components in a matching manner, spanner holding posture adjustment of the user is helpful, and operations are more smooth.
An included angle theta is formed between another port 132 of the second driving head 130 and the grab handle 110, wherein 0 degree < theta < 25 degrees. Like the first driving head 120, the included angle between the port 132 of the second driving head 130 and the grab handle 110 also facilitates improvement of operation smoothness. FIG. 4 is a partial cutaway view of the multifunctional spanner according to the embodiment in FIG 1. The second driving head 130 is hollow and cylindrical, the inner wall of the second driving head 130 are provided with multiple tooth parts, the multiple tooth parts comprise a first tooth part 133 and a second tooth part 134, and the first tooth part 133 and the second tooth part 134 are respectively vertical to the port 131 and the port 132 of the second driving head 130. Therefore, the spanner is convenient to be held by a user by matching with the included angle between the port 131 and the grab handle 110 and the included angle between the port 132 and the grab handle 110.
According to the embodiment provided by the present invention, by adopting the multifunctional spanner provided by the present invention, it can be known that the following advantages are achieved: (1) . the included angle between the grab handle 110 and the first driving head 120 and the included angle between the grab handle 110 and the second driving head 130 help the user to adjust the holding posture, thereby achieving the labor saving effect; (2) . the grab handle 110 is horizontally connected with one end of the first driving head 120 and one end of the second driving head 130, thereby improving the smoothness of the spanner in use; and (3) . the two ends of the grab handle 110 can be provided with embossed patterns 111 which have anti-slip effect.
