[0027] The following combines the drawings and embodiments to describe the utility model in detail.

[0028] Embodiment:

[0029] A screwdriver capable of removing stripped screws is as Figure 1 shown, including a shank 2 and a bit 21. The bit 21 is fixedly connected to one end of the shank 2. The other end of the shank 2 is fixedly connected with a shaft rod 3. Two symmetrical rotating shafts 31 are penetrated through the surface of the shaft rod 3 and located on both sides of the surface of the shaft rod 3. The rotating shaft 31 is rotatably connected with a rotating handle 1. The rotating handle 1 rotates around the rotating shaft 31. The rotating handle 1 rotates from abutting against the shank 2 to abutting against the screw fixing device 4 through the rotating shaft 31. A plurality of through holes are opened on both sides of the rotating handle 1.

[0030] As Figure 2 shown, the end of the shaft rod 3 away from the shank 2 is fixedly connected with a screw fixing device 4. The screw fixing device 4 includes a plurality of side rotating screws 41, a pressure plate 411, a top rotating screw 42 and a top column 421. The side rotating screw 41 is rotatably connected with the pressure plate 411. The top rotating screw 42 is rotatably connected with the top column 421.

[0031] As Figure 3As shown, several protrusions 422 are fixedly connected to the top end of the top column 421, and the protrusions 422 are hexagonal prisms.

[0032] As Figure 4 shown, a rotating clamping shaft 11 is rotatably connected to the end of the rotating handle 1 away from the shaft rod 3. The rotating clamping shaft 11 has a T-shaped structure. A rotating hole is penetrated through the end of the rotating clamping shaft 11 away from the head end, and the rotating hole is rotatably connected to the rotating handle 1.

[0033] As Figure 5 shown, a plurality of grooves are formed in the side wall of the rotating handle 1, and the grooves are in conformity with the shapes of the side rotating screws 41 and the top rotating screws 42.

[0034] One end of the shaft rod 3 is connected with a screwdriver shank 2 and a tool bit 21. One end of the shank 2 is fixedly connected with the tool bit 21, and the other end of the shank 2 is fixedly connected with one end of the shaft rod 3. The other end of the shaft rod 3 is fixedly connected with a fixing screw device 4. The fixing screw device 4 is composed of several side rotating screws 41, a pressing plate 411, a top rotating screw 42 and a top column 421. Among them, the pressing plate 411 is rotatably connected with each side rotating screw 41, and rotating the side rotating screw 41 controls the forward and backward movement of the pressing plate 411. The top rotating screw 42 is rotatably connected with the top column 421, and rotating the top rotating screw 42 controls the up and down movement of the top column 421. The top of the top column 421 is fixedly connected with several small protrusions 422. The small protrusions 422 are hexagonal prisms. The small protrusions 422 can increase the friction with the screw head and can more conveniently screw out the screw. The fixing screw device 4 increases the friction by increasing the effect of the pressure between the object and the surface, increases the friction with the screw to make the screw relatively fixed with the fixing screw device 4, and realizes the fixation of the part of the screw protruding from the plane. The two are used to clamp the screw to take out the screw. Selecting the clamping method can make the screw not easy to shake, improve the stability and accuracy of taking out, and can also avoid actions such as knocking on the screw and damage to the object. Selecting the clamping method can be applicable to screws of different shapes and sizes for clamping. Two symmetric rotating shafts 31 are arranged on both sides of the surface of the shaft rod 3 and penetrate through the surface of the shaft rod 3. The rotating shafts 31 are rotatably connected with a rotating handle 1. The rotating handle 1 is rotatably connected with the shaft rod 3 through the rotating shafts 31. The rotating handle 1 rotates from the fixing screw device 4 to the shank 2. And when it rotates to the two positions, a rotating clamping shaft 11 is rotatably connected to the end of the rotating handle 1 far away from the shaft rod 3. The rotating clamping shaft 11 is T-shaped. When the two rotating handles 1 rotate to the same position, the two can be fixed through the rotating clamping shaft 11, making the rotating handle 1 as a handle more stable. A groove is opened on the inner side of the rotating handle 1, and the shape of the groove is fitted with the side rotating screw 41. When the rotating handle 1 is used as the handle of the shank 2, it can be fitted with the side rotating screw 41 and the top rotating screw 42 on the fixing screw device 4, reducing the friction and impact damage between the two and the rotating handle 1. A number of through holes are opened on both sides of the rotating handle 1. The through holes can allow air to circulate, improve the holding comfort, and can also reduce the weight of the tool, making the tool lighter, saving materials and making it more beautiful.

[0035] During the use process, the screwdriver shank 2 and the tool bit 21 can be used to tighten and loosen normal screws. If the position of the screw head is scratched or the shape is damaged due to improper use, first rotate the rotating handle 1 to the shank 2, and then use the other end to clamp and hold the position of the screw head, and rotate the integrated rotating handle 1 to loosen it, achieving the effect of loosening the stripped screw.

[0036] The above are only the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as within the protection scope of the present utility model.
