[0033] Figure 1 A cross-sectional view of a device for installing a bolt according to an embodiment of the present invention is shown below. Figure 1 Provide a detailed description.

[0034] like Figure 1 As shown, the device includes a screwdriver 110 and a flexible sleeve 120. The screwdriver 110 can be used to tighten the bolt. Specifically, the screwdriver 110 can include a shank 111 and a cutter head 112, wherein the cutter head 112 is fixed to one end of the shank 111 (e.g., Figure 1In some embodiments, the cutter head 112 and the shank portion 111 are of an integral structure, which is not only conducive to simplifying the manufacturing process and reducing production costs, but also conducive to improving the durability and stability of the screwdriver 110. In other embodiments, the cutter head 112 and the shank portion 111 adopt a split structure, and the two are connected by a detachable manner such as a threaded connection. Such a design allows the user to replace the corresponding cutter head 112 according to the model of the bolt, thereby enhancing the versatility and applicability of the device. The flexible sleeve 120 is roughly cylindrical and can be slidably mounted on the screwdriver 110 and can be used to transport the bolt and its accessories to the target position. Specifically, the flexible sleeve 120 includes a first end ( Figure 1 The upper end of the middle), the second end ( Figure 1 The lower end of the flexible sleeve 120), a receiving chamber 121 and a positioning portion 122. The receiving chamber 121 connects the first end and the second end of the flexible sleeve 120, and the receiving chamber 121 is configured to accommodate at least a portion of the bolt, for example, at least the head of the bolt. Optionally, the receiving chamber 121 is also suitable for accommodating accessories of the bolt (such as flat washers, spring washers, etc.). The positioning portion 122 is arranged in the receiving chamber 121, and is used to position the bolt and its accessories to prevent the bolt and its accessories from falling off from the flexible sleeve 120. In addition, the flexible sleeve 120 has a soft texture and elastic deformation ability, so that after the user applies a certain pressure to the screwdriver 110 and / or the bolt, the screwdriver 110 (especially the blade head 112) and / or the bolt can pass through the positioning portion 122 smoothly. For example: by sliding the flexible sleeve 120 along the screwdriver 110, the blade head 112 of the screwdriver 110 can pass through the positioning portion 122, and the blade head 112 can enter and exit the receiving chamber 121 from the second end of the flexible sleeve 120.

[0035] Figure 2a and Figure 2b FIG. 1 shows a schematic diagram of a device in use according to an embodiment of the present invention. Figure 2a and Figure 2bAs shown, when using the device to install the bolt, the bolt and its accessories can be first loaded into the accommodating cavity 121 from the second end of the flexible sleeve 120 (in this process, the flexible sleeve 120 will undergo elastic deformation, allowing the bolt and its accessories to pass smoothly through the positioning portion 122). Then, use the device to send the bolt and its accessories to the target position (for example: a narrow, high aspect ratio space), and use the screwdriver 110 to screw the bolt so that the bolt is screwed into the threaded hole (no need to tighten). Next, slide the flexible sleeve 120 along the screwdriver 110 so that the blade 112 of the screwdriver 110, the bolt and its accessories leave the accommodating cavity 121 from the second end of the flexible sleeve 120 (in this process, the flexible sleeve 120 will undergo elastic deformation, allowing the blade 112 of the screwdriver 110, the bolt and its accessories to pass smoothly through the positioning portion 122). Finally, use the screwdriver 110 to tighten the bolt again to complete the entire installation process.

[0036] According to one embodiment of the present invention, Figure 1 As shown, the head 112 of the screwdriver 110 can be an external hexagonal socket, which can be used to screw an external hexagonal bolt (e.g. Figure 2a and Figure 2b shown). Figure 3a A cross-sectional view of a device according to another embodiment of the present invention is shown. Figure 3a As shown, the blade head 112 of the screwdriver 110 can also be a flat blade head, which can be used to screw a flat head bolt (for example Figure 3b and Figure 3c In other embodiments, the blade head 112 of the screwdriver 110 may also be a cross blade head, a hexagonal blade head, a torx blade head, etc., wherein the cross blade head can be used to screw a cross head bolt, the hexagonal blade head can be used to screw a hexagon socket bolt, and the torx blade head can be used to screw a torx bolt.

[0037] Figure 4 A schematic diagram of a device according to another embodiment of the present invention is shown. Figure 4 As shown, the screwdriver 110 may further include a handle 113, and the shank portion 111 is connected between the handle 113 and the blade head 112. In some embodiments, the handle 113 and the shank portion 111 may be an integral structure, which is beneficial to improving the durability and stability of the screwdriver 110. In other embodiments, the handle 113 and the shank portion 111 may also be a split structure, and the two may be fixed by a threaded connection, an adhesive connection, or the like. Such a design allows the handle 113 to be made of a lighter or lower-cost material, thereby reducing costs. Figure 4 As shown, the handle 113 is connected to one end of the shank portion 111 ( Figure 1 and parallel to the shank portion 111. In other embodiments, Figure 5As shown, the handle 113 and the shank 111 may also be perpendicular to each other, which helps increase the torque applied to the bolt, making it easier for the user to tighten the bolt. Those skilled in the art will appreciate that in some embodiments, the screwdriver 110 may not be equipped with a handle 113, but instead one end of the shank 111 may be configured to be connected to an electric screwdriver (also known as an electric drill), so that the user can use the electric screwdriver to drive the screwdriver 110 to quickly tighten the bolt.

[0038] According to one embodiment of the present invention, Figure 1 As shown, the flexible sleeve 120 may include an inner sleeve 123 and an outer sleeve 124, wherein the inner sleeve 123 is slidably mounted on the outside of the knife bar portion 111, and the outer sleeve 124 is slidably mounted on the outside of the inner sleeve 123. Optionally, an interference fit is adopted between the inner sleeve 123 and the knife bar portion 111, which enables the inner sleeve 123 to stay at any position on the guide rod portion by relying on friction without the need for an additional fixing structure. Optionally, an interference fit may also be adopted between the outer sleeve 124 and the inner sleeve 123, which is conducive to maintaining the relative position of the inner sleeve 123 and the outer sleeve 124 during operation, reducing shaking during sliding, and ensuring the stability and reliability of the entire device during operation. Those skilled in the art will understand that in some embodiments, the flexible sleeve 120 may be an integrated structure (for example Figure 6 As shown), this helps to make the flexible sleeve 120 more compact in structure, more reliable in function, and simplifies the manufacturing and assembly process.

[0039] According to one embodiment of the present invention, Figure 1 As shown, the positioning portion 122 may be provided at the second end of the flexible sleeve 120 to facilitate the user in installing the bolt and its accessories into the flexible sleeve 120 .

[0040] According to one embodiment of the present invention, Figure 1 As shown, the positioning portion 122 can be a positioning ring 125, which can provide stable support for the bolt and its accessories to ensure accurate positioning of the bolt and its accessories in the flexible sleeve 120. In some embodiments, as shown in FIG. Figure 6 As shown, the positioning portion 122 may include a plurality of positioning protrusions 126, which are spaced apart around the circumference of the flexible sleeve 120 to form a uniformly distributed support structure. This support structure not only provides stable support for the bolt and its accessories, but also allows the user to easily install the bolt and its accessories into the flexible sleeve 120, while also reducing the risk of damage caused by misoperation, thereby improving the practicality and safety of the entire device. Optionally, as Figure 6As shown, a plurality of slots 127 can be provided at the second end of the flexible sleeve 120, so that a plurality of elastic sheets 128 are formed at the second end of the flexible sleeve 120, and the plurality of positioning protrusions 126 are distributed on the plurality of elastic sheets 128. The provision of the slots 127 and the elastic sheets 128 makes it easier for the second end of the flexible sleeve 120 to deform, thereby allowing the user to more easily install the bolts and their accessories into the flexible sleeve 120.

[0041] Compared to the prior art, the embodiments of the present invention provide a device for installing bolts that can effectively perform bolt connections in narrow spaces and high-aspect-ratio environments, significantly improving the efficiency and reliability of bolt connections.
