Description

Technical Field

[0001] The utility model belongs to the technical field of socket wrenches, and particularly relates to an anti-dropping socket wrench. Background Art

[0002] Socket wrenches are used when the nut end or bolt end is completely lower than the connected surface, and the diameter of the concave hole cannot be used for open-end wrenches, adjustable wrenches or socket wrenches. The socket head of the socket wrench is a concave hexagonal cylinder; the wrench is usually made of carbon structural steel or alloy structural steel, the head of the wrench has a specified hardness, and the middle and handle parts have elasticity.

[0003] During use, the socket of the wrench needs to be sleeved on the outside of the hexagonal end of the nut or bolt, and then the nut or bolt is turned by rotating the handle. However, during use, as the handle is held and the wrench is rotated, the socket may be skewed with the nut or bolt, resulting in the separation of the socket from the nut or bolt. At the same time, when the nut or bolt is removed, the nut or bolt is likely to fall off the socket, and it is necessary to search for it during recovery, which is rather inconvenient. Content of the Utility Model

[0004] In order to solve the above problems, the purpose of the utility model is to provide an anti-dropping socket wrench.

[0005] To achieve the above purpose, the utility model provides an anti-dropping socket wrench, including a fixed pipe, one end of the fixed pipe is fixedly connected with a counterweight block, the lower surface of the counterweight block is fixedly connected with a hexagonal socket, the inner side wall of the hexagonal socket is slidably connected with three sliding seats, the three sliding seats penetrate through the hexagonal socket, one side of the three sliding seats is fixedly connected with an extrusion plate, the three sliding seats are arranged in a circular array, and a driving component is arranged on the outer side of the fixed pipe, and the driving component is used to drive the sliding seats to slide.

[0006] In an example, the driving component includes a circular ring, both the outer side of the fixed pipe and the inner side of the circular ring are provided with thread grooves, the circular ring is threadedly connected with the fixed pipe, one end of the circular ring is fixedly connected with a tapered pipe, one side of the sliding seat is fixedly connected with a cross bar, a spring is fixedly connected between the cross bar and the hexagonal socket, and the cross bar is located outside the hexagonal socket.

[0007] In an example, placing grooves are arranged at positions near the extrusion plates on the inner side of the hexagonal socket, and the placing grooves are matched with the extrusion plates.

[0008] In an example, the other side of the fixed pipe is fixedly connected with a first circular block, the other side of the first circular block is hinged with a second circular block, and the other side of the second circular block is fixedly connected with a handle.

[0009] In one example, a circular through groove is provided on the handle, a sliding rod is slidably connected in the circular through groove, and both ends of the sliding rod are fixedly connected to limit blocks.

[0011] In one example, one end of the handle is oval-shaped.

[0012] The anti-drop socket wrench proposed by the utility model can bring the following beneficial effects:

[0013] First, by setting a squeezing plate, the sliding seat pushes three squeezing plates to squeeze the three sides of the hexagonal screw inside the hexagonal sleeve, squeezing the screw so that the hexagonal screw and the hexagonal sleeve maintain a relatively fixed static relationship. At this time, the hexagonal screw is rotated by rotating the hexagonal sleeve, and the hexagonal screw will not be easily separated from the hexagonal sleeve, which is convenient for screwing the hexagonal screw. At the same time, when the hexagonal screw is screwed off, the hexagonal screw is located in the hexagonal sleeve, which is convenient for recycling the hexagonal screw.

[0014] Secondly, by arranging the first magnet column and the second magnet column and the first magnet block close to the second magnet block, when the handle and the hexagonal socket are parallel and on the same straight line, the first magnet column and the second magnet column attract and fit each other, and the handle and the hexagonal socket are kept parallel through the first magnet column and the second magnet column. When the handle and the hexagonal socket are perpendicular, the first magnet block is close to the second magnet block, and the first magnet block is close to the second magnet block, so that the handle and the hexagonal socket are kept in a vertical state, avoiding the handle from swinging randomly during use, and being used according to different situations, so that it is more flexible to use.

Detailed implementation manners

[0023] In order to more clearly illustrate the overall concept of the present utility model, the following will be described in detail by way of examples in conjunction with the specification drawings.

[0024] As Figures 1 to 5 shown, an embodiment of the present utility model provides an anti-detachment socket wrench, which includes a fixed pipe 1. One end of the fixed pipe 1 is fixedly connected with a counterweight 2. The lower surface of the counterweight 2 is fixedly connected with a hexagonal socket 3. The inner side wall of the hexagonal socket 3 is slidably connected with three sliding seats 4. The three sliding seats 4 penetrate through the hexagonal socket 3. One side of the three sliding seats 4 is fixedly connected with an extrusion plate 5. The three sliding seats 4 are arranged in a circular array. A drive assembly 6 is provided outside the fixed pipe 1. The drive assembly 6 is used to drive the sliding seats 4 to slide. When the socket is sleeved on a hexagonal screw, the drive assembly 6 drives the three sliding seats 4 to slide. The sliding seats 4 push the three extrusion plates 5 to squeeze the three sides of the hexagonal screw inside the hexagonal socket 3, so as to squeeze the screw and keep the hexagonal screw in a relatively fixed and static relationship with the hexagonal socket 3. At this time, by rotating the hexagonal socket 3, the hexagonal screw can be rotated, and the hexagonal screw will not easily break away from the hexagonal socket 3, which is convenient for screwing the hexagonal screw. At the same time, when the hexagonal screw is unscrewed, the hexagonal screw is located inside the hexagonal socket 3, which is convenient for recycling the hexagonal screw.

[0025] As Figure 2 and Figure 4As shown in the figure, the driving component 6 includes a circular ring 61. Threaded grooves are provided on the outer side of the fixed pipe 1 and the inner side of the circular ring 61. The circular ring 61 is threadedly connected to the fixed pipe 1. One end of the circular ring 61 is fixedly connected to a tapered pipe 62. One side of the sliding seat 4 is fixedly connected to a cross bar 63. A spring 64 is fixedly connected between the cross bar 63 and the hexagonal sleeve 3. The cross bar 63 is located outside the hexagonal sleeve 3. After the hexagonal screw is sleeved in the hexagonal sleeve 3, rotate the circular ring 61. The circular ring 61 rotates on the fixed pipe 1, pushing the inner wall of the tapered pipe 62 to contact the cross bar 63 and squeezing the cross bar 63, causing the sliding seat 4 to slide, pushing the pressing plate 5, so that the pressing plate 5 presses against the side of the hexagonal screw to fix the hexagonal screw. When the hexagonal screw is unscrewed, the hexagonal screw is located in the hexagonal sleeve 3. Reverse the circular ring 61, the tapered pipe 62 leaves the cross bar 63, and the spring 64 pushes the sliding seat 4 to reset. The pressing plate 5 no longer presses the hexagonal screw, facilitating the removal of the hexagonal screw.

[0026] As Figure 4 shown, placing grooves are provided on the inner side of the hexagonal sleeve 3 near the pressing plate 5. The placing grooves cooperate with the pressing plate 5. Initially, the pressing plate 5 is located in the placing groove and will not block the entry of the hexagonal screw into the hexagonal sleeve 3. When the hexagonal screw is smaller than the hexagonal sleeve 3, the pressing plate 5 extends to press and fix the hexagonal screw. At this time, when the hexagonal sleeve 3 is rotated, the hexagonal screw can still be rotated, enabling the device to disassemble hexagonal screws of different sizes and greatly increasing the scope of use.

[0027] As Figure 1 and Figure 2 shown, the other side of the fixed pipe 1 is fixedly connected to a first circular block 7. The other side of the first circular block 7 is hinged to a second circular block 8. The other side of the second circular block 8 is fixedly connected to a handle 9. The upper end of the hexagonal sleeve 3 is hinged to the handle 9, facilitating the control of the hexagonal sleeve 3. The handle 9 can be used parallel to the hexagonal sleeve 3 or rotated to be perpendicular to the hexagonal sleeve 3 for use according to different situations, making the use more flexible.

[0028] As Figure 1 shown, a circular through groove is provided on the handle 9. A sliding rod 10 is slidably connected in the circular through groove. Limit blocks are fixedly connected to both ends of the sliding rod 10. When the handle 9 is parallel to the hexagonal sleeve 3, rotating the handle 9 and the hexagonal sleeve 3 through the sliding rod 10 is more convenient and more convenient for screwing the screw.

[0029] As Figure 2 and Figure 3As shown in the figure, the outer side of the first circular block 7 is rotatably connected to the first rotating ring 11, and the outer side of the second circular block 8 is rotatably connected to the second rotating ring 12. The outer side of the first rotating ring 11 is fixedly connected to the first magnet block 13 and the first magnet column 14, and the outer side of the second rotating ring 12 is fixedly connected to the second magnet block 15 and the second magnet column 16. When the handle 9 and the hexagonal sleeve 3 are parallel and on the same straight line, the first magnet column 14 and the second magnet column 16 attract and fit with each other. Through the first magnet column 14 and the second magnet column 16, the handle 9 and the hexagonal sleeve 3 are kept parallel. When the handle 9 is perpendicular to the hexagonal sleeve 3, at this time the first magnet block 13 approaches the second magnet block 15. By the first magnet block 13 approaching the second magnet block 15, the handle 9 and the hexagonal sleeve 3 are kept in a perpendicular state, preventing the handle 9 from swinging randomly during use.

[0030] As Figure 1 and Figure 2 shown, one end of the handle 9 is oval. One end of the handle 9 is oval, which is convenient for holding and more in line with ergonomics.

[0031] Working principle: Put the sleeve on the hexagonal screw, rotate the circular ring 61. The circular ring 61 rotates on the fixed tube 1, pushing the inner wall of the conical tube 62 to contact the cross bar 63, squeezing the cross bar 63, causing the sliding seat 4 to slide, pushing the pressing plate 5, so that the pressing plate 5 presses against the side of the hexagonal screw to fix the hexagonal screw. Then rotate the hexagonal sleeve 3 through the handle 9. When unscrewing the hexagonal screw, the hexagonal screw is located inside the hexagonal sleeve 3. Reverse the circular ring 61, the conical tube 62 leaves the cross bar 63, and the spring 64 pushes the sliding seat 4 to reset. The pressing plate 5 no longer presses the hexagonal screw, and the hexagonal screw is removed.
