DETAILED DESCRIPTION

[0023] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0024] Various tools are often needed in industrial production and daily life. Due to the wide variety of tools, a large storage space and a reasonable and orderly storage method are required, so management is relatively troublesome. For this reason, some tool manufacturers have developed multifunctional combined tools that can integrate the functions of multiple tools in one tool. One of the functions is a screwdriver. However, the existing multifunctional combined tool screwdriver does not have any structure to lock it after opening, resulting in the screwdriver loosening when tightening the screw, and eventually the screw cannot be tightened or unscrewed, which greatly affects the use. In view of this, the utility model provides a locking structure and a multifunctional tool, which can effectively lock the screwdriver in the multifunctional tool to prevent it from loosening during use.

[0025] Embodiment 1:

[0026] like Figure 1-5 As shown, the locking structure is installed in a multi-function tool, which includes a tool body 1 and a screwdriver 2, wherein the screwdriver 2 is rotatably connected to the tool body 1, a locking groove 3 is provided on the screwdriver 2, and a supporting groove 4 is provided on the tool body 1; the locking structure includes a toggle lock plate 5 and a spring plate 6, wherein the toggle lock plate 5 is rotatably connected to the tool body 1, a locking block 7 is provided at one end of the toggle lock plate 5, a spring pressure groove 8 is provided at the other end of the toggle lock plate 5, and the spring plate 6 is installed in the tool body 1; when the screwdriver 2 is opened, the locking block 7 is clamped in the locking groove 3, one end of the spring plate 6 abuts against the supporting groove 4, and the other end of the spring plate 6 abuts against the spring pressure groove 8.

[0027] When in use, open the screwdriver 2 and rotate the screwdriver 2 to a horizontal position with the tool body 1. At this time, the locking block 7 is clamped in the locking groove 3, one end of the spring sheet 6 abuts in the support groove 4, and the other end of the spring sheet 6 abuts in the spring pressure groove 8, that is, the spring sheet 6 presses the toggle lock sheet 5, so that the toggle lock sheet 5 presses the screwdriver 2, that is, the locking block 7 locks the locking groove 3 to ensure that the screwdriver 2 is locked when in use to avoid looseness. When the screwdriver 2 needs to be closed, the locking sheet 5 is pushed outward so that the locking block 7 exits the locking groove 3, and the screwdriver 2 is rotated at this time. When the screwdriver 2 is retracted into the tool body 1, the spring sheet 6 abuts against one end of the toggle lock sheet 5, so that the toggle lock sheet 5 is automatically reset without the need for additional manual reset.

[0028] like Figure 1 and 2 As shown, in this embodiment, the tool body 1 is provided with a rotating shaft 9, and the screwdriver 2 is rotatably connected to the rotating shaft 9. The toggle lock piece 5 is provided with a rotating shaft 10, and the toggle lock piece 5 is rotatably connected to the tool body 1 through the rotating shaft 10.

[0029] like Figure 1-3 As shown, in this embodiment, the toggle lock piece 5 is provided with a toggle handle 11, and the tool body 1 is provided with a groove 12, and the toggle handle 11 is located in the groove 12. In this structure, the toggle lock piece 5 is provided with a toggle handle 11, and the toggle handle 11 is located in the groove 12. When the screwdriver 2 needs to be closed, it is only necessary to push the toggle handle 11 outwards. After the screwdriver 2 is closed, the toggle handle 11 automatically returns to the groove 12.

[0030] like Figure 1 , 2 As shown in FIG. 4 , in this embodiment, a support block 13 is provided at one end of the spring sheet 6 . When the screwdriver 2 is opened, in this embodiment, the support block 13 abuts against the support groove 4 .

[0031] like Figure 1 , 2 As shown in FIG. 4 , in this embodiment, a pressing block 14 is provided at one end of the spring sheet 6 away from the supporting block 13 , and the pressing block 14 abuts against the spring pressing groove 8 .

[0032] like Figure 1-3 As shown, in this embodiment, a limit block 15 is provided on the toggle lock piece 5, and when the toggle lock piece 5 rotates, the limit block 15 abuts against the pressure block 14. In this structure, when the screwdriver 2 is closed, the limit block 15 abuts against the pressure block 14 to prevent the spring piece 6 from escaping from the spring pressure groove 8, so that the spring always presses the toggle lock piece 5, and after the screwdriver 2 is completely closed, the toggle lock piece 5 can be automatically reset.

[0033] Embodiment 2:

[0034] like Figure 1 , 2 As shown in Figure 6, this embodiment provides a multifunctional tool, including the above-mentioned locking structure.

[0035] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
