For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] Combine the following Figure 1 to Figure 2 , describing a chain movable nail removal tool according to an embodiment of the utility model.

[0026] A chain movable nail removal tool, comprising a mounting base 1, a front handle 2, a rear handle 3, a punching needle 4 and an impact seat 5, wherein the impact seat 5 is fixedly connected to the mounting base 1;

[0027] The rear handle 3 is fixedly connected to the impact seat 5, the front handle 2 is rotatably connected to the impact seat 5, a movable cavity 10 is opened in the middle of the impact seat 5, the impact seat 5 is provided with a pin assembly 6 inside the movable cavity 10, the movable end of the pin assembly 6 is connected to the end of the front handle 2 close to the movable cavity 10, and the pin assembly 6 moves in the movable cavity 10;

[0028] The impact end of the punch needle 4 moves through the mounting seat 1 and the punch pin assembly 6, and the front handle 2 is used to control the movement of the punch pin assembly 6. The movement of the punch pin assembly 6 is used to drive the punch needle 4 to impact the impact seat 5 forward.

[0029] The present invention is a tool for removing movable nails of a chain. The impact seat 5 is placed at the front end of the pin shaft in the chain. Then the impact end of the punch pin 4 passes through the mounting seat 1 and the punch pin assembly 6 and is aligned with the pin shaft. The front handle 2 is connected to the punch pin assembly 6. The staff can drive the punch pin assembly 6 to move by pressing the front handle 2. Since the movement of the punch pin assembly 6 can drive the punch pin 4 to impact the pin shaft forward, the short-distance movement of the punch pin 4 is realized, thereby removing the chain nail, solving the problem that the traditional staff needs to use hammers and nails to remove the chain.

[0030] The present invention also provides a rear handle 3. The designs of the front handle 2 and the rear handle 3 are ergonomic and can improve the user experience of the staff.

[0031] The punch assembly 6 includes a connecting piece 61 and a first spring 62. The end of the connecting piece 61 is hinged to the front handle 2. The end of the connecting piece 61 away from the front handle 2 is sleeved on the punch needle 4. The first spring 62 is movably sleeved on the punch needle 4. The first spring 62 horizontally connects the connecting piece 61 and the mounting seat 1.

[0032] Since the connecting piece 61 and the front handle 2 are hinged, when the staff holds the front handle 2 and the rear handle 3, the staff presses the front handle 2 backward, so that the front handle 2 can drive the bottom of the connecting piece 61 to move forward and compress the spring. At this time, the connecting piece 61 is tilted, so that the inner wall of the through hole on the connecting piece 61 abuts against the punch 4, so that the punch 4 can move forward under the drive of the connecting piece 61.

[0033] Then, the first spring 62 starts to reset, and the first spring 62 drives the connecting piece 61 to move backward, so that the connecting piece 61 and the front handle 2 are quickly reset. During the reset process, the connecting piece 61 is evenly subjected to the force of the first spring 62, so that the connecting piece 61 has a smaller tilt angle when reset, reducing the occurrence of the punch 4 moving backward under the drive of the connecting piece 61.

[0034] It is worth noting that the distance that the punch pin 4 moves forward each time by the punch assembly 6 is certain, so the staff can press the front handle 2 multiple times to make the punch pin 4 abut against the chain, and then push out the chain nail to complete the disassembly work.

[0035] The rear end of the mounting seat 1 is movably sleeved with a second spring 72, the front end of the second spring 72 is connected to the mounting seat 1, the rear end of the second spring 72 is connected to a limiting plate 71, and the end of the limiting plate 71 is movably sleeved on the punching pin 4;

[0036] A limiting portion 12 is disposed at the rear end of the mounting seat 1 , and the top of the limiting piece 71 is engaged with the limiting portion 12 .

[0037] It is worth noting that the second spring 72 is a compression spring. A limiting portion 12 is provided at the rear end of the mounting seat 1 , and the limiting portion 12 is engaged with the top of the limiting piece 71 , so that the top of the limiting piece 71 is fixed to the limiting portion 12 .

[0038] The limiting piece 71 is normally arranged to be tilted and sleeved on the punching needle 4, so that the inner wall of the through hole on the limiting piece 71 abuts against the punching needle 4. At this time, the top of the second spring 72 is pressed by the limiting piece 71, so the second spring 72 has an outward pressing force, which can effectively limit the movement of the punching needle 4 toward the rear end of the mounting seat 1.

[0039] The staff presses the end of the limit plate 71 so that the limit plate 71 compresses the second spring 72 and maintains the vertical direction. At this time, the through hole on the limit plate 71 does not contact the punching needle 4. Therefore, the staff can adjust the position of the punching needle 4 by pressing the limit plate 71.

[0040] The distance between the limiting portion 12 and the outer side wall of the mounting seat 1 is smaller than the natural length of the second spring 72 .

[0041] This solution limits the distance between the limiting portion 12 and the mounting seat 1, so that under normal conditions, the top of the second spring 72 is pressed by the limiting plate 71, causing the limiting plate 71 to tilt under the action of the second spring 72, ensuring that the second spring 72 and the limiting plate 71 cooperate with each other, which can effectively prevent the punch 4 from moving toward the rear end.

[0042] The front handle 2 and the rear handle 3 are both provided with a recessed portion 21 .

[0043] The recessed portion 21 perfectly fits the structure of the human hand. It not only provides a more comfortable grip, but also reduces fatigue that may be caused by long-term use. This design undoubtedly greatly improves the user experience and allows users to enjoy unprecedented comfort when using the handle.

[0044] The mounting seat 1 is provided with a limit block 11 in the movable cavity 10 . The limit block 11 is located at the rear end of the movable cavity 10 . The limit block 11 is used to limit the movable range of the first spring 62 .

[0045] The limit block 11 can limit the range of motion of the first spring 62, and can better control the elasticity and restoring force of the first spring 62, so that the first spring 62 can maintain stable performance in different environments; it can also prevent accidents caused by the loss of control of the first spring 62, and improve the safety of use.

[0046] The impact seat 5 and the mounting seat 1 are fixedly connected by screws 8 .

[0047] The installation process of the screw 8 connection mode is simple, and it can be easily disassembled and repaired. Moreover, the screw 8 connection has good strain capacity, is not easy to break, can meet the fixed connection requirements and the soft connection requirements, and can be suitable for large-scale production and use.

[0048] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
