Description

Technical Field

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

[0002] In fact, screw is a general term, while screws and screw rods are different from each other. Screws are generally called wood screws; they are the kind with a pointed head at the front end, with a larger pitch, and are generally used to fasten wooden and plastic parts. Screw rods are machine screws (mechanical screws), which are the kind with a flat head at the front end, with a smaller and uniform pitch, and are generally used to fasten metal and machine parts.

[0003] During the process of screw connection or disassembly, a screwdriver is usually used to drive the screw to rotate, so as to improve the stability of the entire connection process and prevent it from loosening easily. It is known that in order to facilitate the rotation of the screw, a drive slot is usually opened on the top of the screw, wherein the drive slot is generally of two types, "flat head" and "plum blossom", and the screw is generally driven to rotate. However, the two screwdrivers in the prior art are generally set separately. When using different screws, different screwdrivers need to be carried and then switched according to different screws, which has certain shortcomings. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-6 The utility model provides a technical solution: a switchable screwdriver, comprising a fixing rod 1 and a handle 2 fixedly connected to the fixing rod 1, a screwing rod 3 is arranged inside the fixing rod 1, one end of the screwing rod 3 is arranged with a plum blossom portion 5, and the other end is arranged with a flat head 6; a switching component is arranged inside the fixing rod 1 to switch between the plum blossom portion 5 and the flat head 6; the switching component comprises a limit block 8 slidably connected to the fixing rod 1, an elastic member is arranged between the limit block 8 and the fixing rod 1, and a rotating shaft 9 is arranged between the fixing rod 1 and the limit block 8; an avoidance groove 4 is opened on the fixing rod 1.

[0022] Specifically, the switchable screwdriver includes a fixed rod 1 and a handle 2 fixedly connected to the fixed rod 1. A screw rod 3 is arranged inside the fixed rod 1. Specifically, the screw rod 3 is made of alloy and other materials, and has the characteristics of high hardness and long service life. A plum blossom portion 5 is arranged at one end of the screw rod 3, and a flat head portion 6 is arranged at the other end. The plum blossom portion 5 and the flat head portion 6 are the driving parts on the commonly used screws. At the same time, a switching component is arranged inside the fixed rod 1 to switch between the plum blossom portion 5 and the flat head portion 6. In actual use, there is no need to carry multiple screwdrivers, but only needs to switch between the plum blossom portion 5 and the flat head portion 6, which is easy and labor-saving, and has high efficiency. The switching component includes a limit block 8 slidably connected to the inside of the fixed rod 1, an elastic member is arranged between the limit block 8 and the fixed rod 1, a rotating shaft 9 is arranged between the fixed rod 1 and the limit block 8, and an avoidance groove 4 is opened on the fixed rod 1. In the original state, when the plum blossom portion 5 needs to be used for work, the flat head portion 6 is located inside the fixed rod 1 at this moment. When it is necessary to switch the plum blossom portion 5 and the flat head portion 6, the screw rod 3 is driven to slide horizontally. During the sliding process of the screw rod 3, the flat head portion 6 will be driven to slide out from the inside of the fixed rod 1 until the flat head portion 6 slides to the avoidance groove 4 position. At this time, the screw rod 3 can be driven to rotate. Specifically, the screw rod 3 is rotated 180° so that the plum blossom portion 5 is located inside the fixed rod 1. After that, after the screw rod 3 is loosened, the elastic force of the elastic member will drive the screw rod 3 to slide horizontally so that the plum blossom portion 5 is located inside the fixed rod 1. At this moment, the switching between the plum blossom portion 5 and the flat head portion 6 on the screw rod 3 is realized, which further improves the practicability and work efficiency of the screwdriver. There is no need to carry multiple screwdrivers, and the screwdriver is suitable for wide promotion and use.

[0023] In the embodiment provided by the utility model, a limiting groove 7 is provided inside the fixing rod 1, and the limiting block 8 is slidably connected to the fixing rod 1 through the limiting groove 7, which can further improve the stability of the limiting block 8 when sliding.

[0024] In the embodiment provided by the utility model, the elastic member includes a fixed spring 10, and the fixed spring 10 is arranged between the limiting block 8 and the limiting groove 7, so as to improve the stability of the fixed spring 10 during installation and meet the working requirements.

[0025] In the embodiment provided by the utility model, a fastening groove 11 is provided on the fixing rod 1, and fastening strips 12 adapted to the fastening groove 11 are fixedly connected on both sides of the twisting rod 3, and the fastening strips 12 on each side are respectively plugged into the fastening groove 11. When the plum blossom part 5 or the flat head part 6 is used for work, the fastening strips 12 at this moment will be stuck in the fastening groove 11, reducing the force between the rotating shaft 9, and further improving the service life of the twisting tool.

[0026] In the embodiment provided by the utility model, the handle 2 is provided with anti-skid stripes to reduce the slipping during work. Specifically, the handle 2 is provided with anti-skid grooves to further increase the friction of the handle 2.

[0027] In the embodiment provided by the utility model, a storage groove is opened inside the handle 2. When the plum blossom portion 5 needs to be used, the flat head portion 6 is located in the storage groove. When the flat head portion 6 needs to be used, the plum blossom portion 5 is located in the storage groove to meet work needs.
