[0023] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0024] According to an embodiment of the present invention, the pipe bayonet puller comprises a first piece 1 and a second piece 2, the center of the first piece 1 is hinged to the center of the second piece 2 via a rotating shaft 3, the first end of the first piece 1 has a first portion 11 for entering the bayonet, the second end of the first piece 1 has a first gripping portion 12, the first end of the second piece 2 has a second portion 21 for entering the bayonet, the second end of the second piece 2 has a second gripping portion 22, the second portion 21 has a tongue-shaped piece 211 extending in the first direction, the tongue-shaped piece 211 is for entering the bayonet, the first piece 1 has an overlapping position and a separation position relative to the second piece 2, when the first piece 1 is in the overlapping position, at least a portion of the first portion 11 can overlap with the second portion 21, when the first piece 1 is in the separation position, the first end of the first piece 1 is away from the first end of the second piece 2. Insert the first part 11 of the first piece 1 into the bayonet and pry it. After prying it several times, the bayonet can be removed. For the bayonet that is relatively corroded, the tongue-shaped part 211 of the second part 21 enters the bayonet. Hammer the second piece 2 to vibrate and separate the pipe from the bayonet. Rotate the first part 11 of the first piece 1 and the second part 21 of the second piece 2 to lock the bayonet. The first piece 1 and the second piece 2 cooperate to clamp the bayonet and remove it. The operation is convenient and quick.

[0025] The pipe bayonet extractor according to the embodiment of the present invention has the advantages of being adaptable to operations in narrow spaces and having high removal efficiency.

[0026] In some embodiments, the width of the first portion 11 decreases as the distance from the first grip portion 12 increases to allow for entry of the latch.

[0027] Specifically, the first portion 11 is designed to be conical or wedge-shaped, so that the pin can be guided more easily when inserted and damage to the pin and the pipe in which it is located can be reduced, ensuring that the tool enters the pin stably while reducing damage caused by size mismatch, thereby improving the applicability and safety of the tool.

[0028] In some embodiments, two sides of the first portion 11 are respectively a first arcuate surface 111 and a second arcuate surface 112 , and both the first arcuate surface 111 and the second arcuate surface 112 are convex in a direction away from the second member 2 .

[0029] Specifically, the design of the arcuate surfaces on both sides of the first part 11 can better adapt to the curved surface of the bottom of the bayonet, and the two arcuate surfaces protrude in the direction away from the second piece 2, which can also make the thickness of the first part 11 thinner while maintaining a certain structural strength so as to enter the gap under the bayonet, thereby improving the flexibility and stability of operation. The arcuate surface design helps to evenly disperse the force, avoid damage to the pipeline caused by concentrated force, and improve the convenience of tool operation.

[0030] In some embodiments, the first direction is perpendicular to the extension direction of the second member 2 , and the first end of the second member 2 has a hammering surface 212 , and the hammering surface 212 is used to abut against the pipe.

[0031] Specifically, the hammering surface 212 can be provided with a layer of material with a certain elasticity, such as rubber, so that force can be applied without damaging the pipeline during the hammering. This allows the user to use the tool to apply force to help the bayonet to separate from the pipeline, thereby improving work efficiency. When the worker hammers the second end of the second piece 2, the hammering surface 212 of the first end contacts the pipeline, and the corroded bayonet can be separated from the pipeline by vibration.

[0032] In some embodiments, the thickness of the tongue-shaped piece 211 decreases as the distance from the second piece 2 increases to enter the detent.

[0033] Specifically, the thickness of the tongue-shaped piece 211 becomes thinner as it moves away from the second piece 2. The end of the tongue-shaped piece 211 away from the second piece 2 enters the pin, and the thinned end is convenient for entering the gap between the pin and the pipe. The end of the tongue-shaped piece 211 connected to the second piece 2 is thicker to ensure structural strength and prevent the tongue-shaped piece 211 from bending or even breaking.

[0034] In some embodiments, the first side of the tongue-shaped member 211 has a third arc-shaped surface 2111 , and the third arc-shaped surface 2111 protrudes toward the second gripping portion 22 .

[0035] Specifically, the third curved surface 2111 can better fit the shape of the bayonet and provide stable support. The third curved surface 2111 protrudes in the direction of the second gripping portion 22 to facilitate the tongue-shaped piece 211 to enter the gap between the bayonet and the pipe and pry the bayonet. The curved surface design helps to provide a better fulcrum during operation, prevent the bayonet from sliding, and improve the stability and safety of the tool.

[0036] In some embodiments, the length of the tongue 211 is greater than or equal to the width of the latch.

[0037] Specifically, the length of the tongue-shaped piece 211 is greater than the width of the bayonet, which ensures that the tongue-shaped piece 211 can completely cover the bayonet, thereby facilitating the tongue-shaped piece 211 to cooperate with the first portion 11 of the first piece 1 to lock and remove the bayonet, and the tongue-shaped piece 211 can provide uniform force distribution. This ensures that the bayonet can be lifted stably and evenly, avoiding damage caused by excessive local force. The first portion 11 of the first piece 1 and the tongue-shaped piece 211 cooperate to form an annular locking area, which can prevent the bayonet from falling.

[0038] In some embodiments, the pipe bayonet extractor further includes a lighting component, which is located on the first component 1 and / or the second component 2 and is used to provide lighting.

[0039] Specifically, the lighting element can be an LED light, which is convenient for operation in an environment with insufficient light. The lighting function improves the efficiency and safety of operations in dark or narrow spaces.

[0040] In some embodiments, the pipe pin extractor further includes a magnetic element, which is located on the second portion 21 and is used to absorb the pin.

[0041] Specifically, the magnetic attraction piece can prevent the small bayonet from falling off, making the operation easier. The magnetic attraction function can simplify the operation process, prevent the loss of small parts, and improve the operation efficiency and safety.

[0042] In some embodiments, the first grip portion 12 and the second grip portion 22 are symmetrical about the rotation axis 3 .

[0043] Specifically, the symmetrical design makes the operation more balanced and convenient for using both hands at the same time. The symmetrical grip can provide a more comfortable grip, reduce fatigue during operation, and improve the user experience.
