[0036] Embodiment 2

[0037] Reference Figure 4-Figure 6 A novel screwdriver, the gripping assembly 5 also includes a connecting shaft 20, the connecting shaft 20 is vertically arranged at the end of the extended grip 18 away from the hexagonal shank 2, the connecting shaft 20 is rotatably connected to the extended grip 18, the connecting shaft 20 is slidably connected to the handheld handle 1, and a plug-in hole 21 is provided on one side of the upper and lower ends of the connecting shaft 20, and a plug-in assembly is provided at the inner side of the handheld handle 1 and at a position corresponding to the plug-in hole 21; thereby facilitating the connection of the extended grip 18 with the handheld handle 1, so that the extended grip 18 can rotate;

[0038] The plug-in assembly includes a plug-in spring 22, which is arranged on the inner side of the handheld knife handle 1 and at a position corresponding to the plug-in hole 21. One end of the plug-in spring 22 is fixedly connected to the handheld knife handle 1, and a plug-in block 23 is fixed to the other end of the plug-in spring 22. The plug-in block 23 is slidably connected to the handheld knife handle 1, and the plug-in block 23 is plug-connected to the connecting shaft 20 through the plug-in hole 21; the connecting shaft 20 can be limited by the plug-in block 23 and the plug-in spring 22, so as to avoid the movement of the connecting shaft 20, thereby preventing the extended handle 18 from rotating, thereby improving the stability of the extended handle 18;

[0039] The device provided in this embodiment, through the structural design of the holding component 5, allows the operator to unfold the two extended handles 18, thereby driving the handheld knife handle 1 to rotate by rotating the extended handles 18. The lever principle is used to make it easier to rotate the handheld knife handle 1, reduce the labor intensity of the workers, and improve the practicality of the device.

[0040] The use process of the novel screwdriver provided by the utility model is as follows: when it is necessary to adjust the length of the hexagonal arbor 2, first, by toggling the adjusting paddle 13 in the direction away from the hexagonal arbor 2, the adjusting paddle 13 drives the driving block 12 and the moving ring 10 to move through the connecting rod 11, and the driving block 12 will squeeze the telescopic spring 14 when it moves, so that the telescopic spring 14 absorbs kinetic energy through deformation, and at the same time, when the moving ring 10 moves, the limit on the connecting plate 8 will be gradually cancelled. Because the connecting plate 8 is fixedly connected to the clamping ring 7, the clamping ring 7 moves in the direction away from the hexagonal arbor 2 under the elastic action of the contraction spring 15, so that when the clamping ring 7 moves to the position close to it When the fixed limiting ring 16 is disengaged from the limiting groove 17, the clamping ring 7 cancels the limiting of the hexagonal knife rod 2, and the length of the hexagonal knife rod 2 can be adjusted. When it is adjusted to a suitable length, the adjusting paddle 13 is released. At this time, because the elastic force of the telescopic spring 14 is greater than the elastic force of the contraction spring 15, the telescopic spring 14 pushes the driving block 12 to move in the direction close to the hexagonal knife rod 2, thereby driving the moving ring 10 to move. When the moving ring 10 moves, it squeezes the connecting plate 8, so that the connecting plate 8 drives the clamping ring 7 to move in the direction close to the hexagonal knife rod 2. When the limiting ring 16 moves to the inner side of the limiting groove 17, the limiting of the hexagonal knife rod 2 is completed, thereby completing the adjustment work;

[0041] When it is necessary to rotate the hexagonal knife rod 2, first, the extended handle 18 is unfolded from the inner side of the hand-held knife handle 1. When the extended handle 18 is at a vertical angle to the hand-held knife handle 1, the extended handle 18 is pushed in the direction close to the hand-held knife handle 1, so that the extended handle 18 drives the connecting shaft 20 to move in the direction close to the inner side of the hand-held knife handle 1. When the connecting shaft 20 moves to contact with the plug-in block 23, the connecting shaft 20 will squeeze the plug-in block 23, so that the plug-in block 23 moves in the direction close to the plug-in spring 22. When the connecting shaft 20 moves to the position corresponding to the plug-in hole 21 and the plug-in block 23, the plug-in block 23 moves to the inner side of the plug-in hole 21 under the elastic action of the plug-in spring 22, so that the plug-in block 23 completes the limiting of the connecting shaft 20, thereby preventing the extended handle 18 from sliding on the inner side of the hand-held knife handle 1. Subsequently, the operator rotates the hand-held knife handle 1 by holding the extended handle 18, which can drive the hexagonal knife rod 2 to rotate, thereby effectively reducing the labor intensity of the operator.
