Description

Technical Field

[0001] This utility model relates to the field of tool and fixture technology, and specifically to a device for sharpening screwdrivers. Background Technology

[0002] Mechanical watch parts are usually very small and precise. Screwdrivers are needed when repairing or maintaining mechanical watches. Screwdrivers need to precisely tighten tiny screws, so the precision and sharpness of the tool are very important.

[0003] Generally, high-quality screwdrivers, such as those made in Switzerland or Germany, are typically made of hardened steel, a durable material that is less prone to wear. However, even high-quality screwdrivers can dull over time, especially with frequent use. A dull screwdriver is prone to slipping when tightening screws, potentially damaging the screw head, which is a significant problem for delicate watch parts. Furthermore, when repairing high-end mechanical watches, the shape of the screwdriver tip must perfectly match the screw grooves on the watch. If the tip is worn and mismatched with the screw, forcing its use may scratch the screw or cause stripping.

[0004] When existing screwdrivers become dull, the only options are to replace them or use ordinary whetstones for rough sharpening; there are no specialized tools for sharpening screwdrivers. This invention proposes a tool specifically designed for sharpening screwdrivers to solve the above problems. Utility Model Content

[0005] According to one aspect of the present invention, a device for sharpening screwdrivers is provided, comprising a base and two parallel guide rods.

[0006] Two first sharpening rods are arranged parallel to each other on the base and below the guide rod, and the extension direction of the two first sharpening rods is the same as the extension direction of the guide rod.

[0007] The slider is slidably mounted on the guide rod;

[0008] The first tool mold sleeve is detachably mounted on the slider, and the first tool mold sleeve is provided with a first mounting sleeve hole;

[0009] The screwdriver can be placed in the first mounting sleeve hole, and the working end of the screwdriver penetrates the first mounting sleeve hole and abuts against the two first sharpening rods.

[0010] This invention provides a device for sharpening screwdriver tips, solving the problem of watch repairers frequently replacing screwdrivers or using simple whetstones to keep them sharp. The device consists of a base, a first tool mold sleeve, a slider, and two first sharpening rods. The slider slides along a guide rod on the base. During use, the screwdriver is placed in the first mounting hole, with its working end penetrating the hole and abutting against the two first sharpening rods. By sliding the slider, the working end of the screwdriver rubs against the two first sharpening rods, thus sharpening the screwdriver tip. Furthermore, different first tool mold sleeves are provided for different screwdriver models, allowing the device to sharpen various types of flathead screwdrivers. Professional sharpening ensures the screwdriver regains its sharpness and maintains its original angle and shape, thereby improving the quality of watch repairs.

[0011] In some embodiments, the base includes a base plate and two side blocks, which are respectively installed at both ends of the base plate, and each side block is provided with an elongated groove for mounting the first sharpening rod.

[0012] Thus, the base consists of a base plate and two side blocks, with the two side blocks sandwiching the base plate in the middle to form a base.

[0013] In some embodiments, an apparatus for sharpening screwdrivers further includes a first adjusting bolt, a first screw hole on the upper end face of the side block, the first screw hole communicating with an elongated groove, the first adjusting bolt being mounted on the first screw hole, and one end of the first adjusting bolt abutting against two first sharpening rods.

[0014] Therefore, the distance between the two first grinding rods can be adjusted by turning the first adjusting bolt.

[0015] In some embodiments, a device for sharpening screwdrivers further includes two adjusting springs. A first mounting hole is provided at one end of an elongated groove, and a second mounting hole is provided at the other end of the elongated groove. The first mounting hole and the second mounting hole face each other and are coaxially distributed. The two adjusting springs are respectively disposed in the first mounting hole and the second mounting hole. The adjusting springs abut against the corresponding first sharpening rods, and the two adjusting springs can force the two first sharpening rods to move closer to each other.

[0016] Therefore, the adjusting spring applies a pressing force to its corresponding first sharpening rod, causing the corresponding first sharpening rod to move closer to the other first sharpening rod.

[0017] In some embodiments, an apparatus for sharpening screwdrivers further includes a second adjusting bolt, wherein the side wall of the side block is provided with a second threaded hole communicating with a second mounting hole, the second adjusting bolt is mounted on the second threaded hole, and the second adjusting bolt forces the adjusting spring in the second mounting hole to abut against the first sharpening rod.

[0018] Therefore, the second adjusting bolt controls the clamping force of the first grinding rod by adjusting the compression of the spring.

[0019] In some embodiments, a through hole is provided on the elongated groove of one of the side blocks, the through hole being perpendicular to and communicating with the elongated groove.

[0020] Thus, the through hole is used to insert or replace the first sharpening rod.

[0021] In some embodiments, a device for sharpening screwdrivers further includes several buffer springs, and two third mounting holes for mounting guide rods are provided on the end faces of the two side blocks. The buffer springs are installed in the third mounting holes, and the two ends of the guide rods are elastically supported in the third mounting holes by the buffer springs.

[0022] In some embodiments, a device for sharpening screwdrivers further includes several connecting bolts, several third screw holes on the side blocks, and fourth screw holes on both sides of the base plate. The third screw holes on one side block correspond to the fourth screw holes on the same side of the base plate, and the connecting bolts penetrate the third screw holes and are installed into the fourth screw holes. This invention features a simple structure and convenient operation, making it suitable for widespread promotion and application.

[0023] Therefore, the base plate and the two side blocks are connected and installed using several connecting bolts.

[0024] In some embodiments, the slider has slots on both sides, which cooperate with the guide rods, and the slider is engaged between the two guide rods through the slots.

[0025] Therefore, the slider is installed by snap-fitting, with the slider sandwiched between two guide rods, and the slider slides under the action of the two guide rods.

[0026] In some embodiments, an apparatus for sharpening screwdrivers further includes a second sharpening rod and a second tool mold sleeve. The second sharpening rod is disposed on a base and extends in the same direction as the first sharpening rod. A second mounting groove is provided on the slider, and the second tool mold sleeve is detachably disposed on the second mounting groove. The working end of the screwdriver penetrates the second tool mold sleeve and abuts against the second sharpening rod.

[0027] Therefore, a second sharpening rod was added to grind the lower surface of the screwdriver. Attached Figure Description
