[0050] Although the present invention is susceptible of being embodied in different forms, only some of the specific embodiments are shown in the drawings and will be described in detail in this specification. It should be understood that this description should be regarded as an exemplary illustration of the principles of the invention and is not intended to limit the invention to that described herein.

[0051] Thus, a feature indicated in this specification is intended to illustrate one of the features of one embodiment of the present invention, rather than to imply that every embodiment of the present invention must have the described feature. In addition, it should be noted that this specification describes many features. Although certain features can be combined together to illustrate possible system designs, these features can also be used in other, not explicitly described, combinations. Thus, unless otherwise noted, the described combinations are not intended to be limiting.

[0052] In the embodiments shown in the accompanying drawings, directional indications (such as up, down, inside, and outside) used to explain the structure and movement of various components of the present invention are not absolute but relative. These descriptions are applicable when these components are in the positions shown in the accompanying drawings. If the descriptions of the positions of these components are changed, these directional indications will also change accordingly.

[0053] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these example embodiments are provided so that the description of the present invention will be more comprehensive and complete, and will fully convey the concepts of the example embodiments to those skilled in the art. The accompanying drawings are merely schematic illustrations of the present invention and are not necessarily drawn to scale. Identical reference numerals in the figures indicate identical or similar parts, and thus repeated descriptions thereof will be omitted.

[0054] The preferred embodiments of the present application are further described in detail below in conjunction with the drawings of this specification.

[0055] like Figure 1 and Figure 5 As shown, the present invention provides a pin pulling tool 10 , comprising a base 100 , a pin pulling component 200 , a de-pinning component 300 and a first driving member 400 .

[0056] The pin pulling component 200 is movably connected to the base body 100 and has an accommodating space 201. The accommodating space 201 is configured to allow the pin body 20 to be pulled out to extend into and be connected to the pin body 20 to be pulled out, thereby achieving a fixed connection with the pin body 20 to be pulled out. The accommodating space 201 has a wider range of applications and can be adapted to different pin bodies.

[0057] It is worth noting that the accommodating space 201 in this embodiment should be understood as a macroscopic space, that is, the space where the pin body 20 to be pulled out extends into the pin pulling component 200 should be understood as the accommodating space 201 .

[0058] The unbinding component 300 is connected to the pin pulling component 200 and is at least partially located in the accommodating space 201. The unbinding component 300 is configured so that when the pin body 20 to be pulled out extends into the accommodating space 201, the unbinding component 300 can trigger the triggering part 21 of the pin body 20 to be pulled out, so that the pin body 20 to be pulled out is unblocked from the fixed structure.

[0059] For example, Figure 12 As shown, the pin body 20 to be pulled out includes a latch rod 22, a clamping portion 23 and a triggering portion 21, wherein the clamping portion 23 and the triggering portion 21 are arranged on the latch rod 22, and the latch rod 22 can be connected to a fixed structure (such as a sheet metal part, a plastic part, etc.) to realize functions such as fixing, connecting or positioning the fixed structure. The clamping portion 23 (such as a ball, a buckle, etc.) is movably connected to the latch rod 22. When the latch rod 22 is inserted into the fixed structure, the clamping portion 23 can be clamped with the fixed structure, so that the latch rod 22 is locked to the fixed structure, and the latch rod 22 cannot be separated from the fixed structure. When the triggering portion 21 is triggered, the triggering portion 21 can link the clamping portion 23, so that the clamping portion 23 and the fixed structure are disengaged, thereby realizing that the latch rod 22 is unlocked from the fixed structure, and the latch rod 22 can be pulled out from the fixed structure, and the disengaging component 300 is used to realize the disengagement between the pin body 20 to be pulled out and the fixed structure.

[0060] It should be noted that the card removal component 300 can be designed to always have at least a portion located in the accommodating space 201, or the card removal component 300 can be designed to be located outside the accommodating space 201 and can move relative to the accommodating space to enter or exit the accommodating space 201.

[0061] The first driving member 400 is connected to the pin pulling component 200 and is suitable for driving the pin pulling component 200 to move to pull the pin, thereby realizing automatic pin pulling, which is more labor-saving and convenient.

[0062] In this embodiment, a de-jamming component 300 is provided on the pin pulling component 200. The de-jamming component 300 is used to trigger the triggering part 21 of the pin body 20 to be pulled out, so that the pin body 20 to be pulled out and the fixed structure are de-jammed, avoiding the situation where the pin body and the fixed structure are damaged due to hard pulling of the pin pulling component 200, and pin pulling is more labor-saving and convenient.

[0063] In some embodiments, as Figure 9 and Figure 11 As shown, the card-removing component 300 is movably connected to the pin-pulling component 200, and the card-removing component 300 is configured to move relative to the accommodating space 201 to extend into or out of the accommodating space 201. In this way, the card-removing component 300 has a certain amount of movement, which can more reliably trigger the triggering portion 21 of the pin body 20 to be pulled out.

[0064] Of course, it should be noted that in other embodiments, the card-removing component 300 can also be designed to be fixedly connected to the pin-pulling component 200, that is, the card-removing component 300 does not need to move relative to the pin-pulling component 200. For example, part of the side wall of the accommodating space 201 is formed as the card-removing component 300, and the trigger part 21 is a movable part. When the pin body 20 to be pulled out extends into the accommodating space 201, the trigger part 21 contacts the card-removing component 300 and is then decompressed by the card-removing component 300 and moves, thereby achieving card removal.

[0065] In some embodiments, as Figure 10 As shown, the accommodating space 201 has openings 202 at both ends along the axial direction. One opening 202 is configured to allow the pin body 20 to be removed to extend into or out of the accommodating space 201. The de-jamming component 300 moves along the axial direction of the accommodating space 201 and is configured to extend into or out of the accommodating space 201 through the other opening 202. In this way, the de-jamming component 300 can have a greater range of movement, achieving more reliable triggering of the trigger portion 21 of the pin body 20 to be removed.

[0066] Of course, it should be noted that, in other embodiments, the card removal component 300 may also be designed to move along other directions of the accommodating space 201 , such as radial movement of the accommodating space 201 .

[0067] In some embodiments, the card removal component 300 includes a pusher 310 and a second driver 320. The pusher 310 is connected to the pin removal component 200 and can move relative to the accommodating space 201. The second driver 320 is connected to the pusher 310 and configured to drive the pusher 310. This allows the pusher 310 to automatically trigger the triggering unit 21 through the second driver 320, making it more convenient to use.

[0068] It is worth noting that in other embodiments, the card removal component 300 can also be designed to be manually driven, which is beneficial to reduce the number of parts of the product and reduce costs, or the card removal component 300 can also be designed to be moved by other boosting structures, such as using the elastic force of an elastic part to drive the card removal component 300 to move.

[0069] In some embodiments, as Figure 3 、 Figure 4 、 Figure 6 and Figure 7 As shown, the pushing portion 310 includes a slider 311 and a push rod 312. The slider 311 is movably connected to the pin-pulling component 200 and is adapted to extend into or out of the accommodating space 201. The push rod 312 connects the slider 311 and the second driving member 320 and transmits force between the second driving member 320 and the slider 311. The force transmission achieved by the push rod 312 improves the movement precision of the slider 311.

[0070] For example, the push rod 312 may also be formed by the piston rod of the second driving member 320 , thereby further reducing the number of parts of the product.

[0071] The pin pulling component 200 is provided with a guide structure 203, and the slider 311 is slidably connected to the guide structure 203 and can slide along the guide structure 203. The guide structure 203 is used to guide the movement of the slider 311, thereby further improving the movement accuracy of the slider 311.

[0072] In some embodiments, the second driving member 320 is disposed on the pin pulling member 200 and is configured to move with the pin pulling member 200 when driven by the first driving member 400. The pin pulling member 200 and the base 100 are each provided with an escape opening, through which a portion of the first driving member 400 can extend out of the pin pulling member 200 and move along the escape opening, or the escape opening is configured to allow a driving source to pass through and connect with the second driving member 320.

[0073] For example, the avoidance openings include a avoidance opening 204A formed on the pin pulling component 200, a avoidance opening 204B formed on the base body 100, and a avoidance opening 204C formed on the protective cover 800. The three avoidance openings are connected to each other. The second driving member 320 includes a cylinder, which is arranged in the pin pulling component 200. The driving source includes an air supply pipe, which passes through the three avoidance openings and is connected to the cylinder to supply compressed gas to the cylinder. When the pin pulling component 200 moves under the driving force of the first driving member 400, the card removal component 300 also moves, and the air supply pipe moves accordingly in the avoidance opening, thereby reducing the risk of interference with the movement of the card removal component 300.

[0074] In some embodiments, as Figures 1 to 4 As shown, the pin extraction tool 10 includes a first switch 510 and a second switch 520. The first switch 510 is connected to the first driving member 400 and is configured to control the operation of the first driving member 400. The second switch 520 is connected to the second driving member 320 and is configured to control the operation of the second driving member 320. In this way, the first driving member 400 and the second driving member 320 are respectively controlled by their own switches, which makes the product structure simpler and more convenient to assemble.

[0075] As 5 to Figure 8 As shown, the pin removal tool 10 includes a third switch 530, which is connected to the first driving member 400 and the second driving member 320 and is configured to control the operation of the first driving member 400 and the second driving member 320. In this way, the first driving member 400 and the second driving member 320 are controlled by the same switch, and a single operation can be used to remove the card and remove the pin, which is convenient for the user.

[0076] In certain embodiments, as Figure 6 and Figure 7As shown, the pin pulling tool 10 further includes a transmission member 600 , and the pin pulling tool 10 includes a third switch 530 .

[0077] The pin pulling component 200 has a accommodating cavity 205, in which a stop wall 206 is provided. One end of the transmission member 600 is connected to the first driving member 400, and the other end extends into the accommodating cavity 205 and can move in the accommodating cavity 205 toward or away from the stop wall 206. The other end is provided with a matching portion 610. When the matching portion 610 contacts the stop wall 206, the first driving member 400 drives the pin pulling component 200 to move through the transmission member 600. In this way, the motion redundancy provided by the accommodating chamber 205 is utilized, and the movement distance of the first driving member 400 is greater than the movement distance of the second driving member 320, so that after the third switch 530 is triggered, the first driving member 400 and the second driving member 320 work synchronously. During the movement of the second driving member 320, the first driving member 400 drives the transmission member 600 to move in the accommodating chamber 205. At this time, the matching portion 610 is in contact with the stop wall 206 but has not yet contacted, and the pin pulling component 200 has not yet moved. After the de-carding component 300 abuts the triggering portion 21, the matching portion 610 is in contact with the stop wall 206. At this time, the second driving member 320 no longer continues to drive the de-carding component 300, and the first driving member 400 continues to drive the pin pulling component 200 to move, thereby driving the pin pulling component 200 and the de-carding component 300 to move synchronously to achieve pin pulling.

[0078] In some embodiments, as Figure 2 and Figure 3 As shown, the pin extraction component 200 includes a connecting member 210 and a plurality of contoured pulling heads 220. The connecting member 210 is slidably connected to the base 100. The first driving member 400 is connected to the connecting member 210. The plurality of contoured pulling heads 220 are interchangeably connected to the connecting member 210. The contoured pulling heads 220 define a receiving space 201. In this way, the contoured pulling heads 220 can adapt to pins 20 of different shapes to be extracted. Users can replace the contoured pulling heads 220 according to the specific pin 20 to be extracted, thereby improving the reliability of pin extraction.

[0079] The contoured pulling head 220 is formed into a clamping shape, which makes it easier to fix the pin bodies 20 to be pulled out with different shapes.

[0080] In some embodiments, as Figure 9 and Figure 11 As shown, the connector 210 includes a first connecting plate 211, a second connecting plate 212, and a connecting structure 213. The first connecting plate 211 and the second connecting plate 212 are arranged opposite each other and spaced apart. The connecting structure 213 connects the first connecting plate 211 and the second connecting plate 212. This structure is simple and reduces the weight of the product. The gap between the first connecting plate 211 and the second connecting plate 212 provides clearance for the first driving member 400 and the second driving member 320 to avoid motion interference.

[0081] A sliding groove is provided in the base body 100 , and the sliding groove is slidably connected to the first connecting plate 211 and the second connecting plate 212 and guides the first connecting plate 211 and the second connecting plate 212 .

[0082] In some embodiments, the pin pulling tool 10 further includes a stopper 700 connected to the base 100. The stopper 700 is configured as a hollow structure, and the contoured pulling head 220 is located within the hollow structure. During use, the stopper 700 abuts against the fixed structure to form a fulcrum, facilitating pin pulling, making pin pulling more reliable and labor-saving.

[0083] In some embodiments, an air supply component is further included. The first driving member 400 includes a cylinder. The air supply component is the same as the cylinder and is suitable for supplying air to the cylinder.

[0084] A specific embodiment

[0085] Quick-release pins are widely used in a variety of applications. However, in applications where space is limited, the pins are small and difficult to operate manually. Furthermore, they can easily become stuck or difficult to remove. Currently, most puller tools on the market are only suitable for standard cylindrical locating pins and lack suitable tools for specialized pins.

[0086] The purpose of the present invention is to provide a pin extraction tool 10 for this type of special pin, which can save time and effort to extract the pin when it is stuck or difficult to extract.

[0087] Regarding the structural form of the latch, for example, the latch includes a latch rod 22, a movable part and one or more ball bearings, the one or more ball bearings being located at one end of the latch rod 22 and distributed along the circumference of the latch rod 22, the one or more ball bearings being configured to be able to move relative to the circumferential side wall of the latch rod 22, the movable part being disposed in the latch rod 22 and a portion of which protrudes from the latch rod 22, the movable part being able to move along the circumference of the latch rod 22, the movable part being formed as a button of the latch, the movable part being able to move in conjunction with one or more ball bearings, so that the one or more ball bearings can move relative to the circumferential side wall of the latch rod 22 to protrude from the circumferential side wall or be retracted into the circumferential side wall.

[0088] It can be understood that when the ball protrudes from the side wall, the pin and the fixed structure are in a snap-fit state, and the pin cannot be separated from the fixed structure. When the ball is retracted into the side wall, the lock between the pin and the fixed structure is released, and the pin can be pulled out of the fixed structure. Specific embodiment 1

[0090] This embodiment provides a pneumatic pin pulling tool 10 that utilizes a pneumatic device to achieve pin insertion.

[0091] Specifically, the pneumatic pin extraction tool 10 includes a limit member 700, a contoured pin extraction head 220, a base body 100, a protective cover 800, a floating joint 340, a first drive member 400, a fastener 900, a first drive member mounting seat 410, a protective cover 800, a first switch 510, a second switch 520, a second drive member mounting seat 330, a second drive member 320, a slider 311, and a push rod 312.

[0092] The latch is pulled out using the contoured puller 220, which combines the action of the slider 311 pressing the latch and the retraction of the single-acting cylinder. During use, the appropriate contoured puller 220 is selected based on the latch model to engage the latch. The second switch 520 is manually turned on, establishing communication between the second driver 320 (e.g., a needle cylinder) and the air source. The push rod 312 of the second driver 320 then pushes the slider 311 forward, triggering the button at the top of the latch. This frees the ball bearing at the rear of the latch, allowing the latch to be pulled out of its fixed structure.

[0093] Then, the first switch 510 is turned on, the first driving member 400 is ventilated, and the first driving member 400 drives the contoured pulling head 220 to retract as a whole during the return stroke, thereby pulling out the bolt. Specific embodiment 2

[0095] This embodiment provides a pneumatic pin pulling tool 10 that utilizes a pneumatic device to achieve pin insertion.

[0096] Specifically, the pneumatic pin extraction tool 10 includes a limit member 700 , a contoured pin extraction head 220 , a base 100 , a protective cover 800 , a first driving member 400 , a stop wall 206 , a third switch 530 , a second driving member 320 , a slider 311 , a push rod 312 , and a transmission member 600 .

[0097] During operation, the operator first locks the latch through the contoured puller head 220, and then presses the third switch 530. At this time, the first driving member 400 and the second driving member 320 supply air at the same time. Since there is an idle stroke between the transmission member 600 and the connecting member 210, the second driving member 320 first retracts the latch button through the push rod 312. Then, when the first driving member 400 retracts, it drives the transmission member 600, the connecting member 210 and the contoured puller head 220 to pull out the latch.

[0098] The contoured pull head 220 is fixed on the mounting plate and can clamp the latch. The contoured pull head 220 can be replaced according to latches of different shapes.
