[0001] This utility model belongs to the field of auxiliary screw tightening technology, and specifically relates to an auxiliary screw tightening tool. Background Technology

[0002] When enterprises disassemble and assemble screws during production and maintenance, screws are usually tightened with a screwdriver. The screw angle and position need to be fixed by hand or pliers. However, in some narrow areas, auxiliary tools are required.

[0003] In existing technologies, when fixing screws, it is difficult for operators to reach their arms into the space in narrow areas to align the bolts with the screw holes for installation, which can easily lead to screws falling out and make screw tightening difficult. To address this, we propose an auxiliary screw tightening tool. Utility Model Content

[0004] To address the problem mentioned in the background art where, in confined spaces, operators find it difficult to extend their arms to align the bolts with the screw holes during screw tightening, leading to screws easily falling out and causing difficulties in screw tightening, this utility model provides an auxiliary screw tightening tool.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary screw-tightening tool, comprising a hollow tube and clamping feet, wherein a fixing boss is welded to the outer side of the lower end of the hollow tube, and a limiting plate is fixed on both sides of the fixing boss; clamping feet are symmetrically installed on both sides below the hollow tube, and a telescopic spring is fixed on the side of the clamping feet near the limiting plate.

[0006] A clamping ring is fixed to the inner side below the clamping foot, and an adapter is detachably installed on the inner side of the clamping ring. A positioning block is fixed to one end of the adapter, and a screw head groove is opened on the inner side of the adapter.

[0022] Example 1

[0023] like Figures 1-5 As shown;

[0024] An auxiliary screw-tightening tool includes a hollow tube 1 and clamping feet 5. A fixing boss 4 is welded to the outer side of the lower end of the hollow tube 1. Limiting plates 11 are fixed on both sides of the fixing boss 4. Clamping feet 5 are symmetrically installed on both sides below the hollow tube 1. A telescopic spring 13 is fixed on the side of the clamping feet 5 near the limiting plates 11. A clamping ring 6 is fixed on the inner side below the clamping feet 5. An adapter 7 is detachably installed on the inner side of the clamping ring 6. A positioning block 8 is fixed to one end of the adapter 7. A screw head groove 9 is opened on the inner side of the adapter 7.

[0025] In this implementation plan, the radially opening clamping foot 5 and the slender hollow tube 1 design solve the problem of screws being difficult to fix in narrow areas such as inside the equipment and deep holes. The modular adapter 7 can be quickly replaced and is compatible with various bolt heads such as Phillips, slotted, hex, and Torx bolts, thus improving applicability.

[0026] In an optional embodiment, a telescopic inner rod 3 is telescopically connected to the upper part of the hollow tube 1, and a tube cap 2 is fixed to the top of the telescopic inner rod 3. The hollow tube 1 is stretched to the tube cap 2 by the telescopic inner rod 3, and the telescopic inner rod 3 is fixed to the hollow tube 1 by bolts.

[0027] In this implementation scheme: the telescopic inner rod 3 is slidably connected to the hollow tube 1, and the tool length can be adjusted.

[0028] In an optional embodiment, the clamping ring 6 is sized to match the adapter 7, and the clamping ring 6 is fixed relative to the adapter 7 by a positioning block 8 and screws.

[0029] In this implementation scheme: the clamping ring 6 can be detachably installed with the adapter 7, the adapter 7 is provided with a screw head groove 9 for adapting to different bolt heads, and a positioning block 8 to fix the position of the clamping ring 6.

[0030] In an optional embodiment, the clamping foot 5 is elastically telescopically connected to the limiting plate 11 via a telescopic spring 13, and the clamping foot 5 is slidably engaged with the fixed boss 4.

[0031] In this implementation scheme: the telescopic spring 13 connects the clamping foot 5 and the fixed boss 4, providing clamping and resetting force. The opening action of the clamping foot 5 is achieved by external force pulling, and the closing action is completed by the telescopic spring 13 automatically resetting.

[0032] In an optional embodiment, a limiting rod 12 is horizontally fixed between the limiting plate 11 and the fixed boss 4, and the limiting rod 12 passes through the upper part of the clamping foot 5.

[0033] In this implementation scheme: the limiting rod 12 can limit the movement of the clamping foot 5.

[0034] In an optional embodiment, an anti-slip patch 10 is adhered to the inner wall of the screw head slot 9. The anti-slip patch 10 is made of silicone material with raised teeth.

[0035] In this implementation plan: the anti-slip patch 10 provides mechanical friction to solve the problem of non-magnetic screws easily falling off.

[0036] Working principle: First, select the appropriate accessory 7 matching the bolt head, install the clamping ring 6, and the positioning block 8 on the outside of the clamping ring 6 will lock the clamping ring 6. Then, fix the positioning block 8 and the clamping ring 6 with screws. Next, adjust the length of the pipe body according to the space distance, pull the telescopic inner rod 3 of the pipe cap 2 and the hollow pipe 1 to stretch them to a suitable position, and then fix them with bolts. Next, pull the clamping foot 5 outward. The clamping foot 5 is squeezed by the telescopic spring 13, which drives the clamping ring 6 to move outward, and then the bolt end is locked in the screw head groove 9. The anti-slip patch 10 can improve the connection stability. Qualitative analysis is performed; then the clamping foot 5 is released, and the telescopic spring 13 rebounds, causing the clamping foot 5 to move closer to the end of the bolt to clamp it. The coordinating control of the limiting plate 11 and the limiting rod 12 prevents the clamping foot 5 from shifting. The bolt is then moved to the surface of the workpiece to ensure that the bolt is vertically aligned with the screw hole. Finally, the screwdriver is passed through the hollow tube 1 until it touches the head of the bolt. The screwdriver is pushed forward, and the bolt is disengaged from the screw head slot 9 by axial force. The screwdriver is then continuously rotated until the bolt is screwed into the screw hole. During the operation, there is no need to hold the bolt body with the other hand, which is convenient for operation in narrow spaces.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
