Abstract
Description
Technical Field
[0001] This utility model relates to the field of wrench technology, and in particular to a wrench that can be used for both gas cylinders and cutting torches. Background Technology
[0002] Existing gas cylinder valve opening and closing wrenches are usually fixed square straight handle open wrenches, which can only be used to open and close gas cylinder valves and cannot be used for other purposes. Their use is limited. When it is necessary to adjust or disassemble the cutting torch, only an adjustable wrench or other open handle wrench can be used, which requires preparing another wrench, resulting in low work efficiency and failing to meet the needs of on-site use.
[0003] Therefore, in order to address this problem, this utility model provides a dual-purpose wrench for gas cylinders and cutting torches. Utility Model Content
[0004] The purpose of this utility model is to solve the problems in the prior art by proposing a gas cylinder cutting torch dual-purpose wrench.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A gas cylinder cutting torch dual-purpose wrench includes jaws, a handle fixedly connected to the bottom of the jaws, and an open-end wrench assembly at the end of the handle; wherein the open-end wrench assembly further includes a rotating handle fixedly disposed at the end of the handle, a rotating shaft fixedly connected to the end of the rotating handle, the rotating shaft being rotatably connected to the inside of the handle, and a rhomboid locking post fixedly connected to the bottom of the rotating handle, with a square sleeve fitted on the surface of the rhomboid locking post.
[0007] Preferably, both ends of the rotating shaft extend into the handle and are fixedly connected to rotating gears. The handle has a through groove inside, and a limiting component is slidably connected inside the through groove. The end of the limiting component is located on one side of the rotating gear.
[0008] Preferably, the limiting component includes a U-shaped rod that slides inside the through groove, and both ends of the U-shaped rod are fixedly connected with locking teeth, which are used to engage with the rotating gear.
[0009] Preferably, a sliding block is fixedly connected to the top of the U-shaped rod, the sliding block extends through the handle and beyond, and the surface of the sliding block is provided with anti-slip texture.
[0010] Preferably, a support spring is fixedly connected inside the through groove, and the support spring is fixedly connected to one side of the U-shaped rod.
[0011] Preferably, a guide rod is fixedly connected inside the through groove, the U-shaped rod slides on the surface of the guide rod, and the support spring is sleeved on the surface of the guide rod.
[0012] Compared with the prior art, this utility model provides a dual-purpose wrench for gas cylinders and cutting torches, which has the following advantages:
[0013] This gas cylinder and torch combo wrench integrates a rotating handle, rotating shaft, diamond-shaped locking pin, and square socket, allowing it to be integrated with the jaws and handle. This enables the opening and closing of the gas cylinder and the adjustment and disassembly of the torch to be performed with just one integrated wrench, avoiding the need to switch between multiple wrenches for these tasks and further improving the wrench's operability and work efficiency.

[0019] Example 1:
[0020] Reference Figures 1-4 A gas cylinder cutting torch dual-purpose wrench includes a jaw 1, a handle 2 fixedly connected to the bottom of the jaw 1, and a deadbolt assembly 3 provided at the end of the handle 2; wherein the deadbolt assembly 3 further includes a rotating handle 31 fixedly provided at the end of the handle 2, a rotating shaft 32 fixedly connected to the end of the rotating handle 31, the rotating shaft 32 being rotatably connected to the inside of the handle 2, and a rhomboid locking post 33 fixedly connected to the bottom of the rotating handle 31, and a square sleeve 34 sleeved on the surface of the rhomboid locking post 33.
[0021] In this utility model, the cutting torch can be adjusted and disassembled by setting the jaws 1. When it is necessary to open or close the gas cylinder, the gas cylinder valve surface can be directly fitted by setting the open-end wrench assembly 3 at the end of the handle 2. Then the user controls the handle 2 to rotate the angle, thereby realizing the opening or closing of the valve by the open-end wrench assembly 3. By setting the jaws 1, handle 2 and open-end wrench assembly 3 as an integrated unit, it is possible to realize the opening and closing of the gas cylinder and the adjustment and disassembly of the cutting torch with only one integrated wrench.
[0022] With the rotation of the rotating shaft 32 fixed on the surface of the rotating handle 31 and the handle 2, the diamond-shaped locking post 33 at the end of the rotating handle 31 can be rotated at multiple angles. Since the square sleeve 34 is fitted on the surface of the diamond-shaped locking post 33, the angle of the square sleeve 34 can be changed synchronously. By adjusting the angle, the user can find a more ergonomic operating posture, reduce wrist twisting or excessive force, reduce fatigue, and transmit torque more efficiently. In narrow or complex working environments, the adjustable angle design allows the wrench to flexibly fit nuts or bolts at different angles, avoiding the inability to operate the tool normally due to space limitations.
[0023] Furthermore, it is explained that the diamond-shaped retaining post 33 and the square sleeve 34 are interference fit to ensure the connection strength between the diamond-shaped retaining post 33 and the square sleeve 34. At the same time, the diamond-shaped retaining post 33 and the square sleeve 34 can be disassembled to replace different sizes of the square sleeve 34, thereby adapting to different valve sizes.
[0024] Example 2:
[0025] Reference Figure 1 , Figure 3 and Figure 4 Similar to Embodiment 1, but further: the two ends of the rotating shaft 32 extend into the handle 2 and are fixedly connected to the rotating gear 35. The handle 2 has a through groove 21 inside, and a limit component 36 is slidably connected inside the through groove 21. The end of the limit component 36 is located on one side of the rotating gear 35. The limit component 36 includes a U-shaped rod 361 that slides inside the through groove 21. Both ends of the U-shaped rod 361 are fixedly connected to the locking teeth 362, which are used to engage with the rotating gear 35. A sliding block 363 is fixedly connected to the top of the U-shaped rod 361. The sliding block 363 extends into the handle 2 and outwards. The surface of the sliding block 363 is provided with anti-slip texture. A support spring 37 is fixedly connected inside the through groove 21. The support spring 37 is fixedly connected to one side of the U-shaped rod 361. A guide rod 38 is fixedly connected inside the through groove 21. The U-shaped rod 361 slides on the surface of the guide rod 38, and the support spring 37 is sleeved on the surface of the guide rod 38.
[0026] With the rotating gear 35 at the end of the rotating shaft 32, the rotating shaft 32 can synchronously drive the rotating gear 35 to adjust the angle during rotation. When the required angle is adjusted, the limiting component 36 is inserted into the rotating gear 35 to lock the rotating gear 35. The locking of the rotating gear 35 ensures that the rotating shaft 32 will not rotate, thus ensuring the stability of the rotating handle 31 fixed to the rotating shaft 32. The U-shaped rod 361 included in the limiting component 36 slides in the through groove 21, ensuring the guiding of the movement of the U-shaped rod 361. Then, with the locking teeth 362 at the end of the U-shaped rod 361, when the locking teeth 362 approach the rotating gear 3... At position 5, the rotating gear 35 can be locked. Conversely, when the locking tooth 362 moves away from the rotating gear 35, the locking of the rotating gear 35 can be released, allowing the rotating shaft 32 to be adjusted at any angle. The sliding block 363 above the U-shaped rod 361 facilitates the user's better displacement of the U-shaped rod 361. The anti-slip texture on the sliding block 363 increases the friction of the user's hand. The spring force of the support spring 37 allows the U-shaped rod 361 to be automatically reset. The guide rod 38 further improves the displacement stability of the U-shaped rod 361 and guides the support spring 37.
