[0021] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] like Figures 1 to 6As shown, a typical embodiment of this utility model provides a novel railway turnout wrench, including a handle 1, a sleeve 2, and a screw head 3; the handle 1 includes a first end 1-1 and a second end 1-2, the sleeve 2 includes a first sleeve 2-1 and a second sleeve 2-2, the first sleeve 2-1 is rotatably mounted on the first end 1-1, and the second sleeve 2-2 is rotatably mounted on the second end 1-2, the screw head 3 includes a first screw head 3-1 and a second screw head 3-3, the first screw head 3-1 is disposed inside the first sleeve 2-1, and the second screw head 3-3 is disposed inside the second sleeve 2-2, both the first screw head 3-1 and the second screw head 3-3 are quadrilateral, each face of the first screw head 3-1 has a different specification of insertion hole 3-2, and each face of the second screw head 3-3 is fixedly installed with a different specification of insertion connector 3-4.

[0023] When using it, observe the bolt that needs to be installed or removed, select the appropriate screw head 3, taking the first screw head 3-1 as an example, rotate the first screw head 3-1 so that the insertion hole 3-2 corresponds to the end of the bolt, and put the end of the bolt on, hold the handle 1, drive the sleeve 2 to rotate, so that the bolt is removed or installed.

[0024] Both the first sleeve 2-1 and the second sleeve 2-2 are rotatably installed with ratchet sleeves 4. Both ends of the ratchet sleeve 4 are provided with grooves 4-1, and the connector 3-4 can slide in the grooves 4-1. The inner wall of the ratchet sleeve 4 can contact the outer surface of the screw head 3.

[0025] When the sleeve 2 is rotated, the ratchet sleeve 4 makes it easier to install or remove the bolt. When the screw head 3 is retracted into the ratchet sleeve 4, the connector 3-4 can slide in the groove 4-1, so that the connector 3-4 can be retracted into the ratchet sleeve 4. At the same time, when the screw head 3 is retracted into the ratchet sleeve 4, the outer wall of the screw head 3 contacts the ratchet sleeve 4, so that the screw head 3 can be stably placed in the ratchet sleeve 4. When the sleeve 2 is rotated, it can maintain stability, which facilitates the installation and removal of the bolt.

[0026] Both sides of the first screw head 3-1 and the second screw head 3-3 are provided with movable brackets 3-5. The movable brackets 3-5 are slidably installed in the ratchet sleeve 4. The bottom end of the movable brackets 3-5 is rotatably mounted with a rotating shaft 3-6. The rotating shaft 3-6 is fixedly installed at the center of the outer surface of the screw head 3. A cross-shaped through hole 3-7 is opened on the rotating shaft 3-6. The opening of the through hole 3-7 corresponds to the orientation of the connector 3-4 and the connector hole 3-2.

[0027] When the screw head 3 contacts the bolt, and the sleeve 2 descends, the rotating shaft 3-6 drives the moving frame 3-5 to slide upward relative to the ratchet sleeve 4, so that the screw head 3 can be retracted into the ratchet sleeve 4. When the sleeve 2 is rotated, it can maintain stability and facilitate the installation and removal of the bolt.

[0028] Both ends of the ratchet sleeve 4 are fixedly installed with insert rods 5. Insert rods 5 can be inserted into the through hole 3-7. When insert rods 5 and moving frame 3-5 are in the lowest position, the bottom end of insert rods 5 can contact the outer surface of rotating shaft 3-6. When insert rods 5 and moving frame 3-5 are in the highest position, insert rods 5 can be inserted into the through hole 3-7.

[0029] When the movable frame 3-5 moves downward relative to the ratchet sleeve 4, the screw head 3 can descend to the lowest distance. At this time, the insertion rod 5 disengages from the through hole 3-7, so that the screw head 3 can rotate around the pivot 3-6 as the center, which is convenient for adjusting the insertion holes 3-2 of different specifications.

[0030] After adjustment, press the sleeve 2 down relative to the screw head 3. If the screw head 3 is not parallel to the sleeve 2, the bottom end of the insert rod 5 will contact the outer wall of the rotating shaft 3-6, making it impossible for the screw head 3 to be inserted into the through hole 3-7. At this time, the angle of the sleeve 2 can be adjusted so that the screw head 3 can be inserted into the ratchet sleeve 4, which can effectively prevent the angle of the screw head 3 from shifting, causing the screw head 3 to be unable to be inserted into the ratchet sleeve 4.

[0031] If the screw head 3 is parallel to the sleeve 2, the insert rod 5 can be smoothly inserted into the through hole 3-7, so that the screw head 3 can enter the ratchet sleeve 4, making the bottom surface of the screw head 3 flush with the bottom surface of the sleeve 2, which makes it easier to maintain stability when disassembling the bolt.

[0032] A contact rod 5-1 is slidably mounted on the top of the insertion rod 5. The contact rod 5-1 can contact the rotating shaft 3-6. A connecting rod 5-2 is fixedly mounted on the top surface of the contact rod 5-1. A push rod 5-3 is fixedly mounted on both sides of the connecting rod 5-2. The top end of the push rod 5-3 penetrates the top surface of the ratchet sleeve 4. A first spring 5-4 is fixedly mounted on the top end of the connecting rod 5-2. The top end of the first spring 5-4 is fixedly connected to the ratchet sleeve 4.

[0033] When the screw head 3 enters the ratchet sleeve 4, the rotating shaft 3-6 contacts the contact rod 5-1 and pushes the contact rod 5-1 to move upward, which in turn drives the connecting rod 5-2 to move upward. When the connecting rod 5-2 moves upward, it can compress the first spring 5-4 and drive the push rod 5-3 to move upward.

[0034] When the first spring 5-4 returns to its original position, it can drive the contact rod 5-1 to push downward, so that the screw head 3 can pop out from the ratchet sleeve 4, making it easy to adjust the screw head 3.

[0035] A drive ring 5-5 is fixedly installed at the top of the push rod 5-3. The drive ring 5-5 can move up and down axially in the sleeve 2. A moving rod 5-6 is fixedly installed on the bottom surface of the drive ring 5-5. An extension rod 5-7 is fixedly installed at the bottom end of the moving rod 5-6. The extension rod 5-7 faces the handle 1.

[0036] When the push rod 5-3 moves upward, it can drive the drive ring 5-5 to move upward. When the drive ring 5-5 moves upward, it can drive the moving rod 5-6 to move upward. The moving rod 5-6 drives the extension rod 5-7 to move upward.

[0037] A rotating head 2-3 is fixedly installed on the outer wall of the sleeve 2. An opening 2-4 is provided at the bottom end of the rotating head 2-3. A connector 1-3 is fixedly installed at the end of the handle 1. A rotating rod 1-4 is fixedly installed on the connector 1-3. The center of the rotating rod 1-4 is set as a polygon. The top surface of the extension rod 5-7 can contact the polygon on the rotating rod 1-4.

[0038] After the angles of handle 1 and sleeve 2 are adjusted, sleeve 2 moves downward so that screw head 3 can enter ratchet sleeve 4 and drive extension rod 5-7 to move upward. The top surface of extension rod 5-7 can fit with the center of rotating rod 1-4, so that rotating rod 1-4 is blocked by extension rod 5-7 and can be locked at a specified angle, thus maintaining stability during bolt installation and removal.

[0039] Both ends of the bottom sides of the ratchet sleeve 4 are provided with latches 4-2. The latches 4-2 are slidably installed inside the ratchet sleeve 4. A second spring 4-4 ​​is fixedly installed between the latches 4-2 and the ratchet sleeve 4. A groove 4-3 is opened at the top of the latches 4-2. An inclined surface is provided on the groove 4-3. An inclined plate 4-5 is provided above the latches 4-2. The inclined plate 4-5 can be inserted into the groove 4-3. A connecting bracket 4-6 is fixedly installed on the inclined plate 4-5. A pressing block 4-7 is fixedly installed at the top of the connecting bracket 4-6. The pressing block 4-7 is slidably installed at the center of the top of the ratchet sleeve 4.

[0040] When the screw head 3 enters the sleeve 2, the rotating shaft 3-6 moves upward and squeezes the buckle 4-2, which compresses the second spring 4-4. When the through hole 3-7 corresponds to the buckle 4-2, the second spring 4-4 ​​returns to its original position, and the buckle 4-2 is pushed into the through hole 3-7, locking the screw head 3 inside the ratchet sleeve 4.

[0041] When it is necessary to adjust the screw head 3, press down the pressing block 4-7 with your finger, so that the connecting bracket 4-6 moves down and drives the inclined block to move down. When the inclined block is pressed down, the inclined surface of the groove 4-3 is used to make the inclined block move down and drive the buckle 4-2 to retract. At this time, the through hole 3-7 loses the locking of the buckle 4-2, the first spring 5-4 is reset, and the screw head 3 is ejected from the ratchet sleeve 4, which makes it easy to adjust the angle between the screw head 3 and the handle 1.

[0042] If adjusting screw head 3 is not required, simply remove it from under the bolt and slip it onto the lower bolt.

[0043] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
