As shown in fig. 1, a pin pulling tool 100 for inserting and pulling a pin 200 according to an embodiment of the present invention includes: the first structural member 110, the second structural member 120, the elastic connection member 130 and the pushing member 140.
Specifically, the first structural member 110 includes a jig 111 for connection with the plug pin 200; the second structural member 120 is relatively movably connected to the first structural member 110 in the axial direction of the insertion pin 200 (for example, up-down direction shown in fig. 1); the elastic connection 130 is connected to the first structural member 110 and the second structural member 120, respectively; the pushing member 140 is connected to the elastic connection member 130, and the pushing member 140 is movable with respect to the first structural member 110 and the second structural member 120.
The first structural member 110 is movable relative to the second structural member 120 between a first position, a second position and a third position, when the first structural member 110 is in the first position relative to the second structural member 120, the elastic connecting member 130 is in a free state, when the first structural member 110 is in the second position relative to the second structural member 120, the elastic connecting member 130 drives the pushing member 140 to move so as to unlock the plug pin 200, and when the first structural member 110 is in the third position relative to the second structural member 120, the first structural member 110 drives the plug pin 200 to be pulled out through the clamp 111. In this way, the insertion pin 200 is pulled out by the cooperation between the first structural member 110, the second structural member 120, the elastic connection member 130, and the pushing member 140.
Referring to fig. 2, the elastic connection 130 is switchable between a free state, a first elastic state, and a second elastic state; the first structural member 110 is movable relative to the second structural member 120 between a first position, a second position and a third position, when the first structural member 110 is in the first position relative to the second structural member 120, the elastic connecting member 130 is in a free state, when the first structural member 110 is moved relative to the second structural member 120 from the first position to the second position, the elastic connecting member 130 is switched from the free state to the first elastic state, and the elastic connecting member 130 drives the pushing member 140 to move so as to push the unlocking button 230 of the plug pin 200, so that the plug pin 200 is in an unlocking state, and when the first structural member 110 is moved relative to the second structural member 120 from the second position to the third position, the elastic connecting member 130 is switched to the second elastic state, and the first structural member 110 drives the plug pin 200 to be pulled out through the clamp 111.
During specific operation, when the plug pin 200 is inserted into the target member and needs to be pulled out, the user may use the pin pulling tool 100 of the present embodiment, and before using the pin pulling tool 100, the elastic connection member 130 of the pin pulling tool 100 is in a free state, and the first structural member 110 is in the first position relative to the second structural member 120.
When the pin is pulled out, first, the pin 200 is held by the jig 111 on the first structural member 110.
The pin extraction tool 100 is then operated to move the first structure 110 to the second position relative to the second structure 120. Here, it can be understood that, since the first structural member 110 is fixed to the plug pin 200 by the clamp 111, and the plug pin 200 is fixed to the target, when the plug pin tool 100 is operated, the first structural member 110 is not moved, the second structural member 120 moves, and in this process, the second structural member 120 pushes the elastic connection member 130 to gradually compress to the first elastic state by moving, and the elastic connection member 130 drives the pushing member 140 to move to approach the unlocking button 230 of the plug pin 200 gradually, and then pushes the unlocking button 230 to unlock the plug pin 200.
Then, the pin pulling tool 100 is continuously operated to move the first structural member 110 to the third position relative to the second structural member 120. Here, in the present operation step, since the plug pin 200 needs to be pulled out, that is, the plug pin 200, the clamp 111, and the first structural member 110 need to be gradually moved away from the fixing member in the present operation step, in order to achieve the relative movement of the first structural member 110 and the second structural member 120, the second structural member 120 is fixed, for example, the second structural member 120 may be stopped against a fixing member (for example, a target member) and the first structural member 110 moves in the present operation step. During the process of moving the first structural member 110 from the second position to the third position, the first structural member 110 gradually pushes the elastic connecting member 130 to compress to the second elastic state, and at the same time, the first structural member drives the plug pin 200 to be pulled out from the target member through the clamp 111.
According to the pin pulling tool 100 for the plug pin 200, the plug pin 200 can be pulled out in a time-saving and labor-saving manner under the condition that the plug pin 200 is not easy to pull out, so that the labor is saved, the efficiency is improved, and the cost is reduced.
In one embodiment of the present invention, referring to fig. 2, the elastic connection 130 includes: a first elastic member 131 and a second elastic member 132, one end (e.g., a lower end of the first elastic member 131 shown in fig. 2) of the first elastic member 131 is connected to the first structural member 110 and the other end (e.g., an upper end of the first elastic member 131 shown in fig. 2) is connected to the pushing member 140, and one end (e.g., an upper end of the second elastic member 132 shown in fig. 2) of the second elastic member 132 is connected to the second structural member 120 and the other end (e.g., a lower end of the second elastic member 132 shown in fig. 2) is connected to the pushing member 140. In this way, providing the elastic connection 130 as the first elastic member 131 and the second elastic member 132 allows movement of the pushing member 140 with respect to the first structural member 110 and movement of the pushing member 140 with respect to the second structural member 120, respectively.
Specifically, during use of the pin extraction tool 100, before use of the pin extraction tool 100, the first elastic member 131 and the second elastic member 132 are both in a free state, and the first structural member 110 is in a first position relative to the second structural member 120; firstly, clamping the plug pin 200 by the clamp 111, and operating the pin pulling tool 100 to move the first structural member 110 to a second position relative to the second structural member 120; the second structural member 120 is compressed by moving and pushing the first elastic member 131, the pushing member 140 moves downward relative to the first structural member 110, gradually approaches to the unlocking button 230 of the plug pin 200, triggers the unlocking button 230 of the plug pin 200, enables the clamping portion 220 of the plug pin 200 to be received in the pin body 210 of the plug pin 200, enables the plug pin 200 to be in an unlocking state, then continues to operate the plug pin tool 100, enables the first structural member 110 to move to a third position relative to the second structural member 120, enables the second structural member 120 to be fixedly supported against the target member, enables the plug pin 200, the clamp 111 and the first structural member 110 to gradually move away from the target member, compresses the second elastic member 132, and enables the first structural member 110 to move upward relative to the second structural member 120, and drives the plug pin 200 to be pulled out of the target member through the clamp 111.
In one embodiment of the present invention, referring to fig. 2, the first elastic member 131 and the second elastic member 132 are springs, and the elastic coefficient of the first elastic member 131 is smaller than that of the return spring of the plug pin 200 and smaller than that of the second elastic member 132. In this way, the relative movement between the first structural member 110, the second structural member 120 and the pushing member 140 is achieved by providing the first elastic member 131, the second elastic member 132 and the return spring having different elastic coefficients.
In a specific operation process, before using the pin pulling tool 100, the elastic connection piece 130 of the pin pulling tool 100 is in a free state, when the pin pulling is started, the pin pulling tool 200 is clamped by the clamp 111, the clamp 111 is fixed relative to a target piece, then the first elastic piece 131 is compressed by moving the first structural piece 110, so that the pushing piece 140 contacts the unlocking button 230 of the pin pulling tool 200, the main function of the first elastic piece 131 is to reset the first structural piece 110, and the elastic coefficient is not required to be very high; after the pushing member 140 contacts the unlocking button 230 of the plug member, since the elastic coefficient of the second elastic member 132 is greater than that of the return spring, the pushing member 140 compresses the unlocking button 230, so that the plug pin 200 enters an unlocking state, at this time, the second structural member 120 is fixed relative to the target member, and the return spring of the plug pin 200 is mainly used for resetting the unlocking button 230, and the elastic coefficient is not required to be very high; after the plug pin 200 is put into the unlock state, the jig 111 moves upward with respect to the second structural member 120, and the plug pin 200 is pulled out.
In one embodiment of the present invention, referring to fig. 2, the second structural member 120 may further include a guide rod 121, and the first elastic member 131 and the second elastic member 132 are sleeved on the guide rod 121. In this way, the guide rod 121 ensures the stability of the positions of the first elastic member 131 and the second elastic member 132, so that the compression directions of the first elastic member 131 and the second elastic member 132 are consistent, and since the elastic coefficient of the first elastic member 131 is far smaller than that of the second elastic member 132, the first elastic member 131 is compressed first in the process of moving the first structural member 110 relative to the second structural member 120, and when the pushing member 140 triggers the unlocking button 230 of the plug pin 200, the second elastic member 132 is compressed again, so that the plug pin 200 is pulled out.
In one embodiment of the present invention, referring to fig. 2, the inside of the guide rod 121 has a first channel 1211 extending along an axis (e.g., up-down direction shown in fig. 2), one end of the pusher 140 (e.g., an upper end of the pusher 140 shown in fig. 2) is movably disposed in the first channel 1211, one of the guide rod 121 and the pusher 140 is formed with a first guide slot 1212 extending along the axis and the other is formed with a first guide post 141 extending along a radial direction (e.g., left-right direction shown in fig. 2) of the guide rod 121, and the first guide post 141 is movably fitted in the first guide slot 1212. That is, the first guide slot 1212 may be formed on the guide rod 121, the first guide post 141 may be formed on the pushing member 140, or the first guide post 141 may be formed on the guide rod 121, and the first guide slot 1212 may be formed on the pushing member 140, so that the relative movement of the pushing member 140 with respect to the guide rod 121 may be realized.
Referring to fig. 2, a first guide slot 1212 is formed in the guide rod 121 and penetrates the guide rod 121 along a radial direction of the guide rod 121, a first guide post 141 is formed at one end of the pushing member 140, the first guide post 141 extends radially outward along the guide rod 121, and a radially outer end of the first guide post 141 extends out of the guide rod 121 from inside to outside through the first guide slot 1212. It should be noted that, the first guide post 141 and the first guide slot 1212 cooperate with each other to realize the relative movement of the guide rod 121 and the pushing member 140 in the up-down direction, and meanwhile, the first guide slot 1212 has a limiting effect on the movement of the pushing member 140, when the pushing member 140 moves upward relative to the guide rod 121, the first guide post 141 gradually moves to the upper end edge of the first guide slot 1212, when the first guide post 141 abuts against the upper end edge of the first guide slot 1212, the pushing member 140 cannot move upward relative to the guide post, when the pushing member 140 moves downward relative to the guide rod 121, the first guide post 141 gradually moves to the lower end edge of the first guide slot 1212, and when the first guide post 141 abuts against the lower end edge of the first guide slot 1212, the pushing member 140 cannot move downward relative to the guide post.
Further, one end of the first elastic member 131 (e.g., an upper end of the first elastic member 131 shown in fig. 2) and one end of the second elastic member 132 (e.g., a lower end of the second elastic member 132 shown in fig. 2) are both fixed to the first guide post 141.
In one embodiment of the present invention, referring to fig. 2, the other end of the pusher 140 (e.g., the lower end of the pusher 140 as shown in fig. 1) is formed with a pressing block 142, the pressing block 142 being located outside the first channel 1211, the pressing block 142 being adapted to push the unlocking button 230 of the plug pin 200 to unlock the plug pin 200.
