Description

Technical Field

[0001] The invention relates to the technical field of hardware tools, in particular to a screw sleeve. Background Art

[0002] It is known that a screw sleeve is a tool specially used for tightening screws. Its main functions are: improving work efficiency: compared with manual screwing, using a screw sleeve can be faster and more labor-saving; precise tightening: for screws that need to be tightened precisely, using a sleeve can better control the torque; wide applicability: since different screws require wrenches of different sizes and models, screw sleeves can be used with plugs of different sizes, and have a wider range of applications. The most common ones are sleeves with magnetic suction, and the screws are also metal, so they can be magnetically attracted. However, for sleeves that are not used for metal screws, such as aluminum alloy screws, traditional magnetic suction sleeves cannot attract them, which reduces the practicality of the sleeve. Then a Chinese utility model patent with authorization announcement number CN221270982U appeared, which disclosed a screw sleeve. However, when tightening the screw, sometimes a large amount of plaster and other materials will be blocked, and the lower surface of the screw clamping mechanism at one end of the existing hexagonal plug rod is a smooth surface. If there is a large amount of plaster and other materials blocking the part that needs to be tightened, it will take a lot of effort, and the problem of loose tightening will occur, which cannot meet the use requirements. It is necessary to improve the existing technology. Summary of the invention

[0024] In the description of the present invention, it should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or indirectly connected to the other element.

[0025] In the description of the present invention, it should be noted that the terms "center", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the invention product is usually placed when in use, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third" and the like are only used to distinguish descriptions, and cannot be understood as indicating or implying relative importance. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined. "Several" means one or more, unless otherwise clearly and specifically defined.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below through the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the scope of the present invention. In addition, in the following description, the description of known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0028] Embodiment 1: Refer to FIG. Figure 2 and Figure 3 A screw sleeve includes an insert rod 1 and a screw clamping device 2 arranged on one end of the insert rod 1, wherein the screw clamping device 2 includes a handle rod 21, a sleeve 22 is arranged on the handle rod 21, and a mounting groove 23 for accommodating screws is arranged on the lower end surface of the sleeve 22, and a cleaning piece 24 is arranged on the lower end surface of the sleeve 22. The arrangement of the cleaning piece 24 is conducive to better cleaning of the tightening part if there is a material such as gypsum blocking it, and is conducive to easy tightening to the tightening position, and is also conducive to tightening more firmly, which is more conducive to meeting the use requirements. When the cleaning piece 24 rotates with the sleeve 22, it is conducive to better cleaning of the tightening part if there is a material such as gypsum blocking it, and then it is more conducive to the screw in the sleeve 22 entering the tightening part, which is conducive to the screw being easily tightened to the tightening position, and is also conducive to tightening the screw more firmly, which is more conducive to meeting the use requirements.

[0029] Embodiment 2: It can be explained on the basis of embodiment 1, such as Figure 1 , Figure 2 and Figure 3 As shown, the cleaning member 24 includes protruding teeth 241 arranged on the end face of the sleeve 22. The protruding teeth 241 are evenly spaced on the end face of the sleeve 22. The evenly spaced protruding teeth 241 are arranged in the same direction, which is conducive to reducing the resistance to rotation. The protruding teeth 241 are conducive to better cleaning of the plaster and other materials that block the parts where the screws need to be tightened. Then, it is more conducive to the entry of the screws in the sleeve 22 into the tightening part, which is conducive to the easy tightening of the screws to the tightening part, and also conducive to tightening the screws more firmly, which is more conducive to meeting the use requirements. It is further explained that it also includes chip grooves 242 arranged at intervals on the outer surface of the sleeve 22. This arrangement is more conducive to chip removal. It is further explained that the chip grooves 242 gradually become smaller from the mounting groove 23 of the sleeve 22. This is conducive to reducing the difficulty of production and manufacturing, and is also conducive to chip removal. Figure 4 As shown, it is also to be noted that each chip groove 242 is two arcuate triangular surfaces 2421 arranged on the outer surface of the sleeve 22, and the two arcuate triangular surfaces 2421 form a chip groove 242, which is more conducive to chip removal. It is also to be noted that the arcuate triangular surface 2421 is provided with a chip guide groove 2422, which is conducive to chip removal and dust removal, and is more convenient for users to use. In this embodiment, the chip guide groove 2422 can be provided on both arcuate triangular surfaces 2421, which is conducive to better chip removal. Finally, it is also to be emphasized that the protruding tooth 241 and the sleeve 22 are integrally formed, and this arrangement greatly improves the firmness of the structure.

[0030] Embodiment 3: It can be described on the basis of Embodiment 1 or Embodiment 2, such as Figure 1 , Figure 2 and Figure 4 As shown, a transition portion is provided between the handle rod 21 and the sleeve 22, and the handle rod 21 and the sleeve 22 are formed into one piece through the transition portion, which greatly improves the stability and firmness of the structure.

[0031] The standard parts used in this application document can all be purchased from the market, and the specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology, which will not be described in detail here.

[0032] It should be noted that, although the above embodiments have been described in this article, the scope of patent protection of the present invention is not limited thereby. Therefore, based on the innovative concept of the present invention, changes and modifications made to the embodiments described herein, or equivalent structures or equivalent process changes made using the contents of the present specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields are all included in the scope of protection of the patent of the present invention.
