In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0037] like Figures 1 to 4 As shown, an embodiment of the utility model provides a pin pulling pliers, which includes a first pliers body 1 and a second pliers body 2. The first pliers body 1 includes a first pliers mouth 11 and a first pliers handle 12 connected to each other. The side wall of the first pliers mouth 11 is provided with a positioning portion 13, and the positioning portion 13 is used to abut against the mounting column 4 so that the positioning portion 13 can be supported by the mounting column 4 to form a fulcrum.

[0038] The second pliers body 2 includes a second pliers mouth 21 and a second pliers handle 22 connected to each other. The first pliers body 1 and the second pliers body 2 are rotatably connected, and the first pliers body 1 is located on one side of the rotational connection position, and the second pliers body 2 is located on the other side of the rotational connection position, that is, the first pliers body 1 and the second pliers body 2 are rotationally connected, the first pliers mouth 11 and the first pliers handle 12 are located on the same side of the rotational connection position, the second pliers mouth 21 and the second pliers handle 22 are located on the same side of the rotational connection position, and the first pliers body 1 and the second pliers body 2 are connected to form an outer pliers structure. The side wall of the second pliers mouth 21 is provided with a connecting portion 23, and the connecting portion 23 is used for detachably connecting with the latch 5. The second pliers handle 22 can be rotated close to the first pliers handle 12, and the second pliers mouth 21 can be rotated away from the first pliers mouth 11 and can drive the latch 5 to move through the connecting portion 23, so as to facilitate the latch 5 to be removed from the mounting column 4.

[0039] The second jaw 21 is configured so that when in use, the first pliers handle 12 and the second pliers handle 22 can be held by the user, and the first pliers mouth 11 abuts on the mounting post 4 through the positioning portion 13, which serves as a fulcrum during the force application process and remains motionless. The user holds the first pliers handle 12 and the second pliers handle 22 and applies force. Under the action of external force, the second pliers handle 22 can rotate around the rotating connection position close to the first pliers handle 12 to drive the second pliers mouth 21 to rotate around the rotating connection position. The second pliers mouth 21 can drive the latch 5 to move relative to the mounting post 4 through the connecting portion 23 connected to the latch 5 and remove it from the mounting post 4, thereby realizing the separation of the latch 5 from the mounting post 4. The user only needs to hold the first pliers handle 12 and the second pliers handle 22 with one hand to apply force, and the force application is more controllable. The pin pulling pliers use the abutment between the positioning portion 13 and the mounting post 4 as a fulcrum, which is convenient for the user to apply force, improves the speed and efficiency of pin pulling and the safety of pin pulling, reduces the situation of personal injury and equipment damage, and solves the problem of inconvenience in applying force during the extraction of the latch 5 in the related technology, which is easy to cause personal injury and equipment damage.

[0040] In this embodiment, the size of the second jaw 21 can be smaller than the size of the ear hole 52 of the pin 5, and the top of the second jaw 21 can extend into the ear hole 52 of the pin 5. The connecting portion 23 on the side of the second jaw 21 can not only connect the second jaw 21 with the ear hole 52 of the pin 5, but also limit the connection position of the pin 5 on the second jaw 21 to prevent the pin 5 from detaching from the second jaw 21.

[0041] like Figure 2 and Figures 5 and 6 As shown, in some embodiments, the connecting portion 23 includes one or more of a first snap-on component, a first magnetic component, and a first adhesive component, that is, the connection between the connecting portion 23 and the latch 5 can be a combination of one or more of snap-on, magnetic, and adhesive connection, so that the movement of the second jaw 21 can drive the latch 5 to move. Various connection methods such as snap-on, magnetic, or adhesive connection can be applicable to different models or types of latches 5, and can be selected according to usage needs.

[0042] For example, the connecting portion 23 can be configured as a first magnetic component, and the first magnetic component can be configured to be magnetically attractive. For example, the material of the first magnetic component can be a magnet, and the material of the ear hole 52 of the latch 5 can be designed to be iron or magnetic. After the second pliers mouth 21 is inserted into the ear hole 52 of the latch 5, the latch 5 is magnetically connected to the connecting portion 23, and the second pliers mouth 21 can drive the latch 5 to move.

[0043] like Figures 5 and 6As shown, in some embodiments, the first clamping member is configured as a hook 131, and the hook 131 is arranged on the side wall of the second jaw 21. The hook 131 can be hooked and connected with the ear hole 52 of the pin 5. In this way, the hook 131 can protrude from the side wall of the second jaw 21 and extend outward, or the hook 131 can be recessed in the side wall of the second jaw 21 and extend inward. After the second jaw 21 is extended into the ear hole 52 of the pin 5, it can be hooked and connected with the ear hole 52 of the pin 5 through the hook 131, thereby reducing the possibility of the pin 5 and the second jaw 21 being detached.

[0044] like Figure 1 to Figure 2 As shown, in some embodiments, the connecting portion 23 is arranged at the top position of the second jaw 21, that is, the connecting portion 23 is connected to the side wall of the second jaw 21 near its own top, reducing the distance between the hook 131 and the top of the second jaw 21, so that after the second jaw 21 is extended into the ear hole 52 of the pin 5, the connecting portion 23 and the ear hole 52 of the pin 5 are close to each other, and the connecting portion 23 is easier to connect with the pin 5.

[0045] In some embodiments, the positioning portion 13 is detachably connected to the first jaw 11, and / or the connecting portion 23 is detachably connected to the second jaw 21, and the adjacent detachable connection method may be, but is not limited to, snap connection, bonding, threaded connection, magnetic connection or threaded connection, so that the positioning portion 13 can be removed and replaced from the first jaw 11, and the positioning portion 13 can be replaced to a different size or shape according to the size or shape of the mounting column 4. The connecting portion 23 can be removed and replaced from the second jaw 21, and the connecting portion 23 can be replaced to a different size or shape according to the size or shape of the positioning hole.

[0046] like Figures 1 to 4 As shown, in some embodiments, the positioning portion 13 may also include one or more of a second clamping member, a second magnetic member, and a second adhesive member. The positioning portion 13 may also be connected to the mounting column 4 by one or more of clamping, magnetic attraction, and adhesive bonding, which facilitates connection and disassembly.

[0047] In this embodiment, the second clamping member can be configured as a groove 231, which extends along the length direction of the first jaw 11 and extends to the top of the first jaw 11, so that the side of the mounting column 4 can extend into the groove 231. The groove 231 can abut and limit the first jaw 11 and the mounting column 4, provide stable support, and reduce displacement and shaking of the first jaw 11 and the mounting column 4.

[0048] Furthermore, the cross-sectional profile of the groove 231 is the same as the side wall profile of the mounting post 4 , which can make the side wall of the groove 231 of the first jaw 11 fit more closely with the side wall of the mounting post 4 , thereby reducing shaking and displacement.

[0049] like Figure 1 to Figure 2As shown, in some embodiments, the top of the first jaw 11 is lower than the top of the second jaw 21 to form an operating space, and the operating space is used for the pin 5 to pass through. When in use, after the top of the second jaw 21 and the connecting portion 23 are extended into the ear hole 52 of the pin 5, the first jaw 11 can avoid the position of the pin rod 51 of the pin 5 through the operating space to reduce position interference. The first jaw 11 can be above the pin rod 51 of the pin 5 and abut against the mounting column 4, and the end of the second jaw 21 can also abut against the pin rod 51 for further support.

[0050] In some embodiments, the width of the first jaw 11 is equal to or greater than the width of the second jaw 21 , so as to increase the setting space of the positioning portion 13 and improve the application range of the pin puller.

[0051] like Figures 1 to 4 As shown, in some embodiments, the pin pulling pliers further include an elastic member 3, which is disposed between the first pliers handle 12 and the second pliers handle 22. The elastic member 3 is configured to apply a thrust to the first pliers handle 12 and the second pliers handle 22. With such a configuration, when pulling out a pin, the user needs to hold the first pliers body 1 and the second pliers body 2 so that the two rotate toward each other, and at this time, the elastic member 3 is compressed and stores energy. After the pin pulling is completed, the external force disappears, and the elastic member 3 recovers its deformation and applies a thrust to the first pliers handle 12 and the second pliers handle 22, so that the first pliers handle 12 and the second pliers handle 22 rotate away from each other for resetting, thereby reducing the manual force application operation.

[0052] In this embodiment, the elastic member 3 can be but is not limited to a spring or a columnar member made of elastic material. For example, the elastic member 3 can be a torsion spring, which is more suitable for the rotational elastic reset of the first clamp handle 12 and the second clamp handle 22. The elastic member 3 can push the first clamp handle 12 or the second clamp handle 22 to move and reset.

[0053] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
