[0002] In daily life, screwdrivers and screws are used more and more widely in various products. Household appliances, toys, cars, etc. all require the use of screws to assemble and complete the assembly of products.

[0003] At present, stainless steel cross pan head screws are more and more widely used in various products. When stainless steel screws are used for assembly, the traditional "magnetic" screwdriver head cannot absorb the stainless steel screws. The stainless steel screws can only be pre-installed into the threaded hole, and then the screwdriver head can be used to align with the cross disk on the top of the screw and rotate it for installation.

[0004] However, since stainless steel screws cannot be adsorbed, it is difficult to pre-install stainless steel screws when encountering a relatively narrow working space. It is difficult to place the stainless steel screws in the threaded holes, which makes the installation very inconvenient. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a screw installation tool, which aims to solve the problem that stainless steel screws cannot be adsorbed, and when encountering a relatively narrow working space, the pre-installation of stainless steel screws is more difficult, and it is difficult to place the stainless steel screws in the threaded holes, resulting in very inconvenient installation.

[0006] To achieve the above object, the utility model is implemented through the following technical solution: a screw installation tool, the screw installation tool comprising:

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0032] See also Figure 1-Figure 7 , which is a schematic structural diagram of a screw installation tool provided in one embodiment of the utility model, the screw installation tool comprises a clamp 100 provided on a screwdriver 300 and a fixing member 200 rotatably connected to the clamp 100, wherein:

[0033] Since the traditional "magnetic" screwdriver cannot absorb stainless steel screws, and the screwdriver lacks a structure for fixing the screws, it is difficult to pre-install the stainless steel screws into the threaded holes in a narrow working space, resulting in the inability to install them. Therefore, a clamp 100 is provided on the screwdriver 300. The clamp 100 includes an external threaded portion 110, and a fitting portion 120 and a fixing portion 130 respectively provided at both ends of the external threaded portion 110. The fitting portion 120 is used to fit the outer periphery of the screwdriver 300, and the fixing portion 130 is used to limit the screw 400, so that after the clamp 100 is assembled on the screwdriver 300, the head of the screw 400 can be directly clamped into the fixing portion 130 for installation.

[0034] In order to realize the assembly of the clamp 100 and the screwdriver 300, the fitting part 120 includes a plurality of fitting sheets 121 evenly spaced on the external threaded part 110, and in order to allow the fitting sheets 121 to have an adjustment space for opening and closing, a first clearance groove 122 is provided between any adjacent fitting sheets 121. When the fitting sheets 121 are opened or closed, due to the presence of the first clearance groove 122, the adjacent fitting sheets 121 will not interfere with each other due to the positional relationship, thereby enhancing the fitting effect of the fitting sheets 121 on the outer periphery of the screwdriver 300.

[0035] Furthermore, the inner diameter of the fitting portion 120 away from the end of the external threaded portion 110 is slightly larger than the diameter of the screwdriver 300, so that when the clamp 100 is sleeved on the outer periphery of the screwdriver 300, the fitting sheet 121 can be easily fitted to the circumferential surface of the screwdriver 300, facilitating installation, and then the fixing member 200 is screwed to the external threaded portion 110 to connect the clamp 100 to the screwdriver 300.

[0036] Furthermore, the inner diameter of the external threaded portion 110 is equal to the diameter of the screwdriver 300. When the clamp 100 is mounted on the screwdriver 300, the external threaded portion 110 is adapted to the screwdriver 300, thereby preventing the clamp 100 from shaking on the screwdriver 300.

[0037] In order to limit the screw 400, a fixing portion 130 is provided at the other end of the external threaded portion 110. The fixing portion 130 includes fixing sheets 131 evenly spaced on the external threaded portion 110. Similar to the fitting portion 120, a second clearance groove 132 is provided between any adjacent fixing sheets 131. The end of the fixing sheet 131 away from the external threaded portion 110 is bent toward the side close to the screwdriver 300. The fixing portion 130 is wide at the top and narrow at the bottom, and the inner diameter of the end away from the external threaded portion 110 is not greater than the diameter of the screw 400.

[0038] Due to the inverted cone shape inside the fixing portion 130, when the screw 400 is clamped in the fixing portion 130, due to the existence of the second clearance groove 132, the adjacent fixing plate 131 is squeezed and the port is expanded to allow the screw 400 to be clamped into the fixing portion 130. Then the fixing plate 131 is closed, and the fixing plate 131 grasps the head of the screw 400 to clamp the screw 400 in the fixing portion 130, and the screw 400 is rotated so that the internal screwdriver 300 bit is embedded in the top of the screw 400.

[0039] It should be emphasized that before installing the clamp 100, the fixing member 200 needs to be sleeved on the outer circumference of the screwdriver 300 in advance. When the clamp 100 is assembled, the fixing member 200 is rotatably connected with the clamp 100 to fix the clamp 100 on the screwdriver 300. The inner circumference of the fixing member 200 is provided with a curved surface portion 220 and an internal thread portion 210. When the internal thread portion 210 and the external thread portion 110 are rotatably connected, the curved surface portion 220 presses the bonding sheet 121 so that the bonding sheet 121 is firmly attached to the circumferential surface of the screwdriver 300, until the external thread portion 110 and the internal thread portion 210 are tightened, the bonding sheet 121 is locked on the screwdriver 300, and then the clamp 100 is fixed on the screwdriver 300. Due to the limiting effect of the fixing portion 130 , even in a relatively narrow working space, after the screwdriver 300 bit is pre-installed with the screw 400 , the screw 400 will not be separated from the screwdriver 300 , and the screwdriver 300 can be directly used for installation.

[0040] It should be emphasized that due to its universal function, the screw installation tool in the present application can be installed on a screwdriver with a magnetic function, and can also be used for a non-magnetic screwdriver. At the same time, it can have a gripping effect on stainless steel screws and screws made of other materials. Even when working in a narrow space, the screws can be firmly grasped for installation.

[0041] In summary, according to a screw installation tool provided by the utility model, a clamp is sleeved on the screwdriver bit, and the clamp is fixed to the periphery of the bit by a fixing member. The screw can be restricted on the screwdriver bit by the clamp, and cannot easily fall off the screwdriver bit even in a narrow working space. Specifically, the screw installation tool includes a clamp and a fixing member. The clamp is sleeved on the screwdriver bit, and its end away from the bit is attached to the periphery of the screwdriver, and the fixing member is rotatably connected to the periphery of the clamp to fix the clamp to the periphery of the screwdriver. The bit is arranged inside the clamp, and when the screw is clamped into the clamp, the screw is rotated so that the bit is embedded in the top of the screw. At the same time, due to the restriction of the clamp, the screw cannot be easily separated from the bit, ensuring that even in a narrow working space, after the screwdriver is embedded in the screw, it can be directly used for installation.
