Description

Technical Field

[0001] The utility model relates to the technical field of screwdrivers, in particular to a screwdriver with a variable rotation angle. Background Art

[0002] A screwdriver is a common tool used to turn screws into place, usually with a thin wedge-shaped head that can be inserted into the slot or notch of the screw head; when a screwdriver is used to pry open the paint cover, it utilizes the working principle of a lever; the greater the distance from the power point to the fulcrum, the less effort is required, so a long screwdriver is more labor-saving than a short screwdriver; when a screwdriver is used to tighten screws, it utilizes the working principle of a wheel and axle; the larger the wheel, the less effort is required, so using a thick-handled screwdriver is more labor-saving than using a thin-handled screwdriver. Screwdrivers are often used in daily life, so optimization of screwdrivers is necessary.

[0003] For example, a screwdriver is disclosed in a Chinese utility model patent with announcement number CN211805806U. In the above prior art, although the screwdriver rod can rotate multiple times through the gear transmission structure after the internal rotating sleeve rotates one circle, that is, the screw can be turned multiple times, thereby improving the efficiency of screwing the screw, the length of the screwdriver itself is fixed. When the screwdriver needs to be used in a narrow space, the screwdriver can only be tilted and cannot be used vertically because the length of the screwdriver itself is greater than the narrow space. When the screwdriver is used tilted, it cannot cooperate well with the screw and is very easy to slip, resulting in the screw being unable to be installed tightly or removed. Therefore, it is necessary to design a screwdriver with a variable rotation angle that can bend the blade of the screwdriver in a narrow space to reduce the overall length of the screwdriver for easy use in a narrow space. Utility Model Content

[0004] In order to solve the technical problem that a screwdriver cannot be used completely vertically in a narrow space, the utility model provides a screwdriver with a variable rotation angle.

[0012] Through the above technical solution, after the two fixing columns are inserted into the fixing holes, the two magnets will attract each other to prevent the fixing columns from loosening.

[0013] As a further improvement of the above scheme, the auxiliary component includes limit columns arranged on both sides of the first screwdriver body, a first auxiliary ring slidably mounted on the two limit columns and slidably matched with the first screwdriver body, and a second auxiliary ring slidably mounted on the two limit columns and slidably matched with the first screwdriver body, the first auxiliary ring and the second auxiliary ring are both arranged in the shape of the character "Ω", and both ends of the two limit columns are fixedly installed with limit plates, both ends of the first auxiliary ring and both ends of the second auxiliary ring are provided with springs mounted on adjacent limit columns, one end of the four springs are fixedly installed with adjacent limit plates, one end of the first fixed column is fixedly installed with the first auxiliary ring, and one end of the second fixed column is fixedly installed with the second auxiliary ring.

[0014] Through the above technical solution, the first fixing column and the second fixing column can be pulled out by pulling the first auxiliary ring and the second auxiliary ring for movable fixation.

[0015] As a further improvement of the above solution, a third fixing hole penetrating the second screwdriver body is provided on one side of the second screwdriver body, and movable grooves providing a moving range for the first fixing column and the second fixing column are provided on both sides of the third fixing hole.

[0016] Through the above technical solution, the two fixing columns can be moved inside the movable groove by only pulling a part of the first auxiliary ring and the second auxiliary ring in coordination with the movable groove.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model provides a bending component, a fixing component and an auxiliary component, so that when the screwdriver cannot be used vertically in a narrow space, the two auxiliary components are pulled to move the fixing component, and the bending component loses its fixing effect, so that the screwdriver can be bent. After bending, the auxiliary component is slid to allow the fixing component to fix the bending component. In this way, the height of the screwdriver can be reduced as a whole, so that the screwdriver can be used in a narrow space. BRIEF DESCRIPTION OF THE DRAWINGS

A rotating groove matching the rotating block 501 is opened at one end of the first screwdriver body 2, and one side of the sliding block 502 is fixedly mounted on the inner wall of the rotating groove. The rotating block 501 cooperates with the sliding block 502, so that the first screwdriver body 2 can drive the handle 1 to rotate.

[0029] Combination Figure 1-Figure 4 A plurality of first fixing holes 8 penetrating the rotating block 501 are provided on one side of the rotating block 501, and a second fixing hole 9 penetrating the sliding block 502 is provided on one side of the sliding block 502. The fixing assembly includes a first fixing column 601 arranged on one side of the first screwdriver body 2 and a second fixing column 602 arranged on the other side of the first screwdriver body 2. The ends of the first fixing column 601 and the second fixing column 602 close to each other are fixedly installed with mutually matching magnets 10. One end of the first fixing column 601 and one end of the second fixing column 602 successively penetrate the first screwdriver body 2 and the adjacent first fixing hole 8 and extend to the inside of the second fixing hole 9. The two magnets 10 cooperate with each other inside the second fixing hole 9. The first fixing column 601 and the second fixing column 602 can be inserted into the first fixing hole 8 and the second fixing hole 9 to fix the first screwdriver body 2 and the second screwdriver body 3.

[0030] Combination Figure 2 , Figure 4 and Figure 5The auxiliary component includes a limiting column 701 arranged on both sides of the first screwdriver body 2, a first auxiliary ring 702 slidably mounted on the two limiting columns 701 and slidingly matched with the first screwdriver body 2, and a second auxiliary ring 703 slidably mounted on the two limiting columns 701 and slidingly matched with the first screwdriver body 2. The first auxiliary ring 702 and the second auxiliary ring 703 are both arranged in the shape of the character "Ω". Both ends of the two limiting columns 701 are fixedly installed with limiting plates 11. Both ends of the first auxiliary ring 702 and the second auxiliary ring 703 are provided with springs 12 mounted on adjacent limiting columns 701. One end of each spring 12 is fixedly installed on the adjacent limiting plate 11, one end of the first fixing column 601 is fixedly installed on the first auxiliary ring 702, and one end of the second fixing column 602 is fixedly installed on the second auxiliary ring 703. A third fixing hole 13 penetrating the first screwdriver body 2 is provided on one side of the first screwdriver body 2, and moving grooves 14 are provided on both sides of the third fixing hole 13 to provide a moving range for the first fixing column 601 and the second fixing column 602. The first fixing column 601 and the second fixing column 602 can be pulled out by pulling the first auxiliary ring 702 and the second auxiliary ring 703 for moving and fixing.

[0031] The implementation principle of a screwdriver with a variable rotation angle in the embodiment of the present application is as follows: when the screwdriver cannot be used perpendicular to the screw in a narrow space, the sliding block 502 is used to cooperate with the rotating block 501 to rotate the handle 1 and the first screwdriver body 2 along the rotating block 501 to form a bend at a certain angle, and the first auxiliary ring 702 and the second auxiliary ring 703 are pulled to pull the first fixing column 601 and the second fixing column 602 out of the third fixing hole 13 and move along the moving groove 14. Due to the existence of the moving groove 14, it is not necessary to pull out the first fixing column 601 and the second fixing column 602 very much. Only a part of it needs to be pulled out to move in the moving groove 14. After 02 moves to the hole position that passes through the first screwdriver body 2, the first fixing column 601 and the second fixing column 602 will be inserted into the first fixing hole 8 and the second fixing hole 9 under the push of the first auxiliary ring 702 and the second auxiliary ring 703 driven by the spring 12, and the two magnets 10 will also be attracted to each other inside the second fixing hole 9, so that the sliding block 502 will be fixed and cannot be moved using the sliding groove. In this way, the handle 1 and the first screwdriver body 2 will also be fixed, and the rotation angle will be changed from vertical rotation at one point to large-range rotation after bending. The overall height of the screwdriver after bending is reduced, so that it can cooperate vertically with the screw in a small space. In this way, even if the space is small and only a part can be rotated at a time, the installation or removal of the screw can be completed.

[0032] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
