[0028] Please refer to Figure 1 , Figure 2 as well as Figure 3 In order to solve the problem that the pins cannot be replaced individually when the pins are damaged, the utility model proposes an aviation plug pin remover 1000, comprising:

[0029] The handle 1 and the plug 2, the handle 1 includes a grip 11 and a locking member 12, the grip 11 and the locking member 12 are movably connected; the grip 11 and the locking member 12 enclose a mounting cavity 1a; the locking member 12 forms a through hole 12a connected to the mounting cavity 1a; the plug 2 includes a needle 21 and a positioning block 22, the positioning block 22 abuts against the inner wall of the mounting cavity 1a; the needle 21 is connected to the positioning block 22 and penetrates the through hole 12a. When the plug 2 is withdrawn, the locking member 12 is locked with the grip 11, the positioning block 22 is limited in the mounting cavity 1a, and the user holds the grip 11 and uses the needle 21 to push the wires on the aviation plug out.

[0030] In the technical solution of the present utility model, when the pin 2 is damaged, the locking state of the locking piece 12 and the holding piece 11 is unlocked, the positioning block 22 is withdrawn from the installation cavity 1a, and the locking piece 12 is separated from the holding piece 11, and then the needle 21 is pulled out from the through hole 12a of the locking piece 12 to complete the separation of the pin 2 and the handle 1. Therefore, when the pin 2 is damaged, the pin 2 can be replaced separately, which is convenient for users to use and avoids waste of resources.

[0031] The form of the movable connection between the holding member 11 and the locking member 12 can be that buckles are respectively provided on the holding member 11 and the locking member 12, and the holding member 11 and the locking member 12 are movably connected through the buckle connection; or threads are formed on the holding member 11 and the locking member 12, and the holding member 11 and the locking member 12 are movably connected through the cooperation between the thread structures. In one embodiment, the holding member 11 and the locking member 12 are threadedly connected.

[0032] It can be understood that the threaded connection between the grip 11 and the locking member 12 can be formed by forming an external thread on the grip 11 and an internal thread on the locking member 12, so that the grip 11 and the locking member 12 are threadedly connected; or it can be formed by forming an internal thread on the grip 11 and an external thread on the locking member 12, so that the grip 11 and the locking member 12 are threadedly connected. In one embodiment, an internal thread is formed at one end of the grip 11 close to the locking member 12; the locking member 12 includes a threaded section 121 and a tightening section 122, and the threaded section 121 is threadedly connected to the grip 11; the positioning block 22 is limited to the end of the threaded section 121 facing the grip 11, and the tightening section 122 is connected to the end of the threaded section 121 away from the positioning block 22. The user can hold the tightening section 122 and rotate the locking member 12 to complete the locking and unlocking between the locking member 12 and the grip 11, which is convenient for the user.

[0033] A plurality of positioning protrusions 111 are formed on one end of the gripping member 11 facing the positioning block 22, and a slot 22a is formed on the positioning block 22 corresponding to each positioning protrusion 111, and each positioning protrusion 111 is inserted into a slot 22a to limit the positioning block 22. In one embodiment, two positioning protrusions 111 are formed on one end of the gripping member 11 facing the positioning block 22, and two slots 22a are formed on the positioning block 22, and each positioning protrusion 111 is inserted into a slot 22a to limit the positioning block 22. The positioning block 22 is arranged in the installation cavity 1a formed by the holding piece 11 and the locking piece 12. The inner wall of the installation cavity 1a limits the positioning block 22 to prevent the positioning block 22 from moving. Two positioning protrusions 111 are formed on the holding piece 11 and inserted into the slot 22a on the positioning block 22, which can prevent the positioning block 22 from rotating in the installation cavity 1a. In this way, the positioning block 22 can be prevented from shaking when the needle 21 withdraws the wire, making the wire pushing process of the aviation plug needle remover 1000 more stable.

[0034] In one embodiment, the sum of the lengths of the threaded section 121 and the positioning block 22 extending in the length direction of the gripping member 11 is greater than the depth of the installation cavity 1a extending in the length direction of the gripping member 11. When the gripping member 11 and the locking member 12 are locked, the length of the threaded section 121 is long enough to extend deep into the installation cavity 1a, so as to ensure that the positioning block 22 can be pushed to a position abutting against the inner wall of the installation cavity 1a, thereby ensuring that the gripping member 11 and the locking member 12 can clamp the positioning block 22 to limit the positioning block 22, thereby preventing the positioning block 22 from shaking in the installation cavity 1a and affecting the stability of the aviation plug needle remover 1000 when pushing the wire.

[0035] It can be understood that a plurality of anti-slip strips 1221 are formed on the outer wall of the tightening section 122. In one embodiment, twenty anti-slip strips 1221 are formed on the outer wall of the tightening section 122. When the user holds the tightening section 122 to rotate the locking member 12, the anti-slip strips 1221 can prevent the user's hand from sliding relative to the tightening section 122, thereby avoiding the situation where the user's strength is too small to unscrew the locking member 12, and facilitating the use of the user.

[0036] In one embodiment, the plug pin 2 further includes a connector 23, which is inserted into the through hole 12a and at least partially extends outside the through hole 12a; the needle 21 is connected to one end of the connector 23 extending outside the through hole 12a, and the positioning block 22 is connected to one end of the connector 23 away from the needle 21. Since the holes of some aviation plugs are arc-shaped or have an inclined angle, the needle 21 may bend slightly when the plug pin 2 is inserted into the aviation plug. This arrangement avoids the situation where the needle 21 abuts against the hole wall of the through hole 12a when it is bent and is broken, thereby improving the service life of the plug pin 2 to a certain extent.

[0037] Specifically, the diameter of the positioning block 22 is larger than the diameter of the through hole 12a, and the cross-sectional area of ​​the connecting piece 23 is larger than the cross-sectional area of ​​the needle 21. The diameter of the positioning block 22 is larger than the diameter of the through hole 12a, which can prevent the positioning block 22 from slipping out of the through hole 12a and causing the entire aviation plug needle remover 1000 to fail; generally, the connecting piece 23, the needle 21 and the positioning block 22 are made of the same material, and the cross-sectional area of ​​the connecting piece 23 is larger than the cross-sectional area of ​​the needle 21, so that the structural strength of the connecting piece 23 is greater than the structural strength of the needle 21, so the force required to break the connecting piece 23 is greater than the force required to break the needle 21, so that the plug is less likely to be broken by the hole wall of the through hole 12a, thereby improving the service life of the plug pin 2.

[0038] In one embodiment, the needle head 21 , the connecting member 23 and the positioning block 22 are integrally formed, so that the overall structural strength of the insertion pin 2 is higher, thereby increasing the service life of the insertion pin 2 .

[0039] In one embodiment, the handle 1 further includes an anti-skid pad 13, which is sleeved on the outer wall of the grip. When the user holds the grip to rotate the locking member 12, the anti-skid pad 13 can prevent the user's hand from sliding relative to the grip, thereby avoiding the situation where the user's strength is too small to unscrew the locking member 12, and facilitating the use of the user.

[0040] Specifically, the material of the anti-slip pad 13 can be rubber or silicone. In one embodiment, the material of the anti-slip pad 13 is rubber. Since the action of unscrewing the locking member 12 is that the user's hand rotates the grip 11, and the action of using the aviation plug needle remover 1000 to push the wire is that the user's hand applies force along the length direction of the handle 1, and the force directions of the user's hands in the two actions are inconsistent, and both require preventing the user's hands from sliding relative to the grip 11, rubber is preferably used as the material of the anti-slip pad 13. The rubber anti-slip pad 13 can provide friction for the user's hands in all directions. Therefore, the rubber anti-slip pad 13 can prevent the user's hands from sliding relative to the grip 11 in both usage scenarios.

[0041] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
