DETAILED DESCRIPTION

[0026] The utility model will be further described below in combination with the drawings:

[0027] The orientation terms involved in the paragraphs of detailed description are only for the convenience of the person skilled in the art to understand the technical solutions recorded in the application according to the visual orientation shown in the drawings. Except for explicit provisions and limitations, the terms "set", "install", "connect" and the like should be understood broadly, and for the person skilled in the art, the specific meanings of the above terms in the utility model can be understood according to the specific circumstances.

[0028] For example, Figures 1 to 7As shown, an adjustable double-head screwdriver includes a handle 2, which includes a handle compartment 201. The handle compartment 201 is cylindrical and hollow inside. Four internally connected limit holes 202 are provided on each side of the upper portion of the handle compartment 201. A sliding groove 204 is provided above the limit holes 202, which is internally connected. A clip 203 is provided between the two sliding grooves 204 and fixed to the outside of the handle compartment 201. The clip 203 can be clipped to clothing for easy carrying. A fixed limit 205 is provided at the bottom of the inner side of the handle compartment 201. The upper end of the fixed limit 205 is fixedly connected to a limit baffle 206. The upper end of the limit baffle 206 is fixedly connected to the upper end of the handle compartment 201. The two sides of the limit baffle 206 are fixedly connected to the inner wall of the handle compartment 201. The limit baffle 206 separates the two sets of adjustment rods 3 and the telescopic mechanism 4 to prevent interference between the two sets of adjustment rods 3 and the telescopic mechanism during operation. An adjustment rod 3 is slidably connected to the interior of the handle compartment 201. A telescopic mechanism 4 is fixedly connected to the bottom of the adjustment rod 3. The adjustment rod 3 has threads on its bottom, and a threaded hole is located on the top of the telescopic mechanism 4, screwing the two together. The telescopic mechanism 4 is slidably connected to the handle compartment 201. A screwdriver bit 5 is fixedly connected to the bottom of the telescopic mechanism 4. The bottom of the handle compartment 201 is fixedly connected to the storage compartment 1. The handle compartment 201 has threads on its bottom, and the storage compartment 1 has threads on its top, rotating the two together. A screwdriver bit 5 is fixedly connected to the storage compartment 1.

[0029] like Figure 4 As shown, the adjustment rod 3 includes a rod body 301, the upper portion of which abuts against the upper portion of the handle compartment 201. A sliding block 302 is provided on one side of the rod body 301, which cooperates with the sliding groove 204. A limiting block 303 is provided on the other side of the rod body 301, which cooperates with the limiting hole 202. The sliding block 302 is responsible for sliding and retracting, while the limiting block 303 is responsible for limiting the position. The telescopic mechanism 4 includes a telescopic column 403 fixedly connected to the rod body 301. The upper end of the telescopic column 403 is fixedly connected to the base 401. A spring 402 is slidably connected to the outer side of the telescopic column 403. One end of the spring 402 abuts against the base 401, and the other end abuts against the upper portion of the fixed limit 205. The fixed limit 205 has two openings to facilitate the sliding of the telescopic column 403. The bottom of the telescopic column 403 is flush with the bottom of the fixed limit 205. The bottom of the telescopic column 403 is provided with a hexagonal groove 404, and the bottom of the hexagonal groove 404 is fixedly connected to the telescopic column magnet 405. The telescopic column 403 is prismatic, and the opening on the fixed limiter 205 is also prismatic.

[0030] like Figure 5As shown, the bit 5 includes a hexagonal prism 503 fixedly connected to the hexagonal groove 404. The advantage of setting it as a hexagonal prism is that when applying force, the force can be evenly distributed among the six prisms. If there are too few prisms, the force shared by each prism will be too great, causing damage to the bit 5. If there are too many prisms, excessive force may cause damage to the prisms. One end of the hexagonal prism 503 is fixedly connected to the bit column 501, which is cylindrical. The bit column 501 has a cutter head 502 fixedly connected to one end. There are six bit 5s in total, and each cutter head 502 is different, making it convenient to replace different bit 5s during use. The telescopic column magnet 405 attracts the bit 5.

[0031] like Figure 6 As shown, the storage bin 1 includes a bin body 101, with a storage bin magnet 103 fixedly connected to the bottom of the bin body 101. The advantage is that it can not only fix the screw bits 5 placed in the bin body 101, but also can be placed on a workbench when in use. The outer side of the bin body 101 can absorb the removed screws to prevent the screws from being lost after removal. Three storage plates 102 are fixedly connected to the inner wall of the bin body 101. Each layer of the storage plates 102 is provided with four cylindrical openings with a diameter consistent with the screw bit columns 501. The screw bits 5 are placed in the cylindrical openings, and the storage bin magnet 103 absorbs the screw bits 5. The advantage is that the screw bits 5 are better fixed and will not become loose.

[0032] The adjusting rod 3 in the present invention is made of plastic and is connected to the telescopic column 403 by setting a thread. The advantage of using plastic for the adjusting rod 3 is that when the sliding block 302 is pressed to telescope the telescopic column 403, the plastic itself is soft in texture, so the force required to disengage the limit block 303 from the limit hole 202 is relatively small, and the operation is easy. In addition, the plastic has good elasticity. When pressed to the desired position, the limit block 303 will return to the limit hole 202.

[0033] Usage process: Remove the storage bin 1 from the handle 2 body, determine the type of screw to be installed, take out the corresponding bit 5 from the storage bin 1, and magnetically attract it to the telescopic column magnet 405 in the hexagonal groove 404. Press the sliding block 302 inward to disengage the limit block 303 from the limit hole 202. Move the sliding block 302 downward to allow the telescopic column 403 to drive the bit 5 to extend downward. When it slides to the appropriate distance, the limit block 303 snaps into the limit hole 202. At this time, the bit 5 can be installed and removed. It is worth noting that the telescopic column 403 is a prism and the opening in the fixed limit 205 is also prism-shaped. Therefore, when holding the handle 2 and forcing to install or remove the screw, the force point is between the telescopic column 403 and the fixed limit 205, and the adjustment rod 3 only serves to adjust the telescopic limit of the bit and is not subjected to force.

[0034] Finally, although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
