Description

Technical Field

[0001] The utility model relates to a hand tool, in particular to a hand tool for a hexagonal wrench. Background Art

[0002] Normally, disassembling and installing high-locking screws with clearance fits requires two-hand coordination (one hand on the ratchet, the other on the hexagon socket). However, when performing certain specialized tasks, such as assembling fasteners inside the S15 blind hole in the wheel well, executing the FR16-20 double splicing command with the forward galley intact, or replacing the high-locking screws inside the cabin floor beam, coordination is difficult due to the confined work area and the short lever arm travel. This can easily cause the hexagon socket to tilt and dislodge, causing damage to the screw hole, failure, and even disengagement, leading to the risk of repeated disassembly and secondary injury. Furthermore, the narrowness of the holes increases the risk of hand jamming and injury. Utility Model Content

[0038] like Figure 1 、 Figure 2As shown, the utility model provides a wrench assembly for a hexagon socket, comprising an upper insert bracket 1, a lower insert bracket 2, a hexagon socket 100 and a wrench 3.

[0039] In order to ensure aesthetics and comfortable operation, the contour shapes of the upper insert bracket 1 and the lower insert bracket 2 are designed to be consistent and smooth, so that when the upper insert bracket 1 and the lower insert bracket 2 are connected together on the left, the upper insert bracket 1 and the lower insert bracket 2 can form a smooth whole with consistent contours.

[0040] The upper blade bracket 1 and the right end of the lower blade bracket 2 clamp the right end of the wrench 3 in the middle, and the left end of the wrench 3 forms an angle with the upper blade bracket 1 and the lower blade bracket 2. To ensure that it can be used in the smallest possible space and can be operated with one hand, the angle is generally less than 90 degrees, so that the space occupied by the left end of the wrench 3, the upper blade bracket 1 and the lower blade bracket 2 is relatively small.

[0041] The hexagon socket 100 passes through the upper insert bracket 1, the wrench 3 and the lower insert bracket 2 in sequence along the axial direction (i.e., the direction perpendicular to the surfaces of the upper insert bracket 1 and the lower insert bracket 2), and the hexagon socket 100 forms a fixed whole with the upper insert bracket 1, the wrench 3 and the lower insert bracket 2.

[0042] Because the hexagon socket 100 is connected to the upper insert bracket 1, the wrench 3, and the lower insert bracket 2 as a fixed unit, when in use, only one hand is needed to hold the wrench 3, the upper insert bracket 1, and the lower insert bracket 2. The extended end of the hexagon socket 100 is aligned with the high locking pin or fastener to be operated, and single-handed operation is possible. For different models of hexagon sockets 100, the insertion hole size of the hexagon socket 100 can be adjusted to adapt to different sizes of hexagon sockets.

[0043] Optionally, a transfer rod 4 is further included, which is axially arranged at the connection ends of the upper insert bracket 1, the wrench 3, and the lower insert bracket 2, and is respectively connected to the upper insert bracket 1, the wrench 3, and the lower insert bracket 2. That is, the upper insert bracket 1, the wrench 3, and the lower insert bracket 2 are connected into one piece through the transfer rod 4.

[0044] In order to ensure the most labor-saving during use, the hexagon socket 100 should be set at the center of the transfer rod 4, so a through hole 405 (such as Figure 4 As shown), the through hole 405 is loosely matched with the hexagon socket 100.

[0045] Optionally, the transfer rod 4 is connected to the upper insert bracket 1 via threads, the transfer rod 4 is connected to the wrench 3 via gears, and the transfer rod 4 is clearance-fitted to the lower insert bracket 2 .

[0046] In order to realize the above connection between the adapter rod 4 and the upper insert bracket 1, the wrench 3 and the lower insert bracket 2, as shown in FIG. Figure 4 As shown, the adapter rod 4 includes a square top 401, a columnar embedded portion 402, a gear coupling portion 403 and a threaded end 404 from top to bottom. The square top 401, the columnar embedded portion 402, the gear coupling portion 403 and the threaded end 404 are concentrically arranged, and the through hole 405 is arranged at the axis center.

[0047] The threaded end 404 is connected to the upper insert bracket 1 , the gear coupling portion 403 is connected to the wrench 3 , and the columnar embedded portion 402 is embedded in the lower insert bracket 2 .

[0048] like Figure 3 As shown, to connect the threaded end 404 to the upper insert bracket 1, a mounting portion 101 is provided at the right end of the upper insert bracket 1. A circular mounting groove 102 is provided within mounting portion 101. A fourth mounting hole is provided at the bottom of mounting portion 101, which is clearance-matched with the hexagon socket 100. The fourth mounting hole is concentric with mounting groove 102. A nut 8 is positioned within mounting groove 102, which threadably engages with threaded end 404. To ensure stability, nut 8 is secured to mounting groove 102, preventing the adapter rod 4 from rotating during use.

[0049] like Figure 3 As shown, the connecting end of the wrench 3 is provided with an inner gear ring 301 , and the inner gear ring 301 is adapted to the gear on the surface of the gear coupling portion 403 .

[0050] Optionally, the right end of the lower insert bracket 2 is provided with a first mounting hole 201, the left end is provided with two second mounting holes 202, and the middle portion of the lower insert bracket 2 is provided with a third mounting hole 203. The first mounting hole 201 is clearance-matched with the columnar embedded portion 402.

[0051] like Figure 3 As shown, two second mounting holes 202 and one third mounting hole 203 are provided on the upper insert bracket 1 at positions corresponding to the second mounting holes 202 and the third mounting holes 203, respectively. A first screw 5 is provided in the second mounting hole 202, and a second screw 6 is provided in the third mounting hole 203. The first screw 5 and the second screw are used to tighten the upper insert bracket 1 and the lower insert bracket 2 as a whole.

[0052] like Figure 2 As shown, a fifth mounting hole is provided on the side of the mounting portion 101 along the radial direction of the fourth mounting hole. The fifth mounting hole is connected to the fourth mounting hole. A top screw 7 is provided in the fifth mounting hole, and the top screw 7 abuts the hexagon socket 100. The top screw 7 can apply a force to the hexagon socket 100 to ensure that the hexagon socket 100 does not rotate during operation.

[0053] Optionally, since the lower insert bracket 2 and the upper insert bracket 1 sandwich the wrench 3, to ensure overall aesthetics and comfortable operation, a downwardly projecting platform is provided at the left end of the lower insert bracket 2. The height of the projecting platform corresponds to the thickness of the wrench 3. The projecting platform is in contact with the upper insert bracket 1, and the second mounting hole 202 passes through the projecting platform.

[0054] The utility model provides a tool for a hexagonal wrench, which has the following advantages:

[0055] 1. Improve efficiency: The manual assembly of the wrench can replace different types of adapter rods and can replace multiple sizes of hexagon sockets. It can be used with a variety of high-locking nails, effectively solving the problem of fastener assembly difficulties during the construction of small and medium spaces in structural repairs, and improving the efficiency of structural fastener assembly.

[0056] 2. Cost savings: This wrench can be used not only in special working positions, but also for general assembly tasks. It improves efficiency while ensuring the safety of small tools, reduces the probability of damage to fasteners, and saves costs.
