[0030] Referring to Figures 1 to 4 , the pin taking and installing device of the present invention includes a frame 10, a sliding member 30, a pin seat 90, and a driving mechanism. One end of the frame 10 is provided with a placement position 11 for placing the pin-bearing structural member, and a hand-held portion 12 is formed below the other end; the sliding member 30 is installed on the frame 10, and the sliding member 30 can slide relative to the frame 10 to approach or move away from the placement position 11; the pin seat 90 is installed on the sliding member 30. One end of the pin seat 90 close to the placement position 11 is provided with a pin-taking needle installation hole 91 and a pin installation groove 92. The pin-taking needle installation hole 91 is used for installing the pin-taking needle 100, and the pin installation groove 92 is used for installing a pin (not shown in the figure). The pin seat 90 can rotate relative to the sliding member 30 to adjust the positions of the pin-taking needle installation hole 91 and the pin installation groove 92; the driving mechanism includes a rotating member 20 and a transmission mechanism. The rotating member 20 is hinged on the frame 10. The lower end of the rotating member 20 forms a gripping portion 22, and the upper end forms a pushing portion 23. When the gripping portion 22 moves close to the hand-held portion 12, the pushing portion 23 pushes the sliding member 30 to slide through the transmission mechanism, so as to drive the pin-taking needle 100 in the pin-taking needle installation hole 91 or the pin in the pin installation groove 92 to move, for pin-taking or pin-installing.

[0031] When the pin extractor and installer of the present invention is in use, place the pin-structured component on the placement position 11, rotate the pin seat 90 to adjust the position so that the pin extractor 100 or the pin is aligned with the pin position of the pin-structured component. Then, grip the gripping portion 22, so that the pushing portion 23 drives the sliding member 30 to slide through the transmission mechanism, driving the pin extractor 100 or the pin to extract or install the pin on the pin-structured component. The pin extractor and installer of the present invention can not only extract the pin in the car key, but also install the pin in the car key. It has a simple structure, and can drive the sliding member 30 to slide through the gripping portion 22 to achieve pin extraction or installation, which is more convenient, faster and more labor-saving.

[0032] As one of the implementation manners, the pin-structured component can be the car key 120. Of course, the pin extractor and installer of the present invention can also be applicable to other components with pin structures.

[0033] Furthermore, there are some concave portions on the handheld portion 12, which play a role in anti-slip.

[0034] As one of the implementation manners, the frame 10 includes a fixed seat 15 and a frame body 17. The fixed seat 15 is located on one side of the frame body 17. The surface of the fixed seat 15 close to the frame body 17 forms the placement position 11. The lower part on the other side of the frame body 17 forms the handheld portion 12. The sliding member 30 is located between the fixed seat 15 and the frame body 17. In this way, a working space is formed by the spaced arrangement between the fixed seat 15 and the frame body 17. The sliding member 30 can move in the working space, and the car key 120 can enter the working space from the side and be placed on the placement position 11, which is more convenient for operation. When extracting or installing the pin, the placement position 11 of the fixed seat 15 is used for support and bearing, which is more stable, and the pin 100 or the pin is not easily broken. Moreover, the whole pin extractor and installer forms a gun-shaped structure, and the design conforms to the ergonomic design, which is convenient and labor-saving for operation.

[0035] Furthermore, there is also a pin receiving hole 16 on the placement position 11 of the fixed seat 15. When extracting the pin, the pin of the car key 120 is pushed away from the car key 120 by the pin extractor 100 and enters the pin receiving hole 16.

[0036] Furthermore, the frame 10 further includes a guide post 14. One end of the guide post 14 is fixedly connected to the fixed seat 15, and the other end is fixedly connected to the frame body 17. The sliding member 30 is installed on the guide post 14 and can slide along the guide post 14, so that the movement of the sliding member 30 during work is more stable. The number of the guide posts 14 can be one, two or more than two.

[0037] As one of the implementation manners, the transmission mechanism includes a pushing block 40 and a first elastic member 50. The pushing block 40 is movable relative to the frame 10. The first elastic member 50 is located between the pushing block 40 and the sliding member 30. The pushing portion 23 is configured to push the pushing block 40 when the gripping portion 22 approaches the handheld portion 12, so that the pushing block 40 pushes the sliding member 30 through the first elastic member 50. Specifically, the first elastic member 50 is not connected to the pushing block 40. When the gripping portion 22 is gripped, the pushing portion 23 pushes the pushing block 40, so that the pushing block 40 compresses the first elastic member 50. The first elastic member 50 pushes the sliding member 30, so that the pin seat 90 moves forward to achieve pin removal or pin installation. As one of the implementation manners, the first elastic member 50 may be a spring.

[0038] As Figures 1 to 3 As shown in the figure, the rotating member is hinged to the frame 10 through a hinge shaft 21. As one of the implementation manners, the frame 10 is provided with a movement space 13 for the pushing block 40 to move. The pushing portion 23 includes a push rod, and at least a part of the push rod is located in the movement space 13 and is configured to push the pushing block 40. Further, both ends of the push rod are fixed to the rotating member, and the middle part passes through the movement space 13.

[0039] As one of the implementation manners, the movement space 13 is provided on the frame body 17 and is located above the handheld portion 12. In this way, the transmission mechanism, the sliding member 30, and the fixed seat 15 are arranged in sequence along the length direction of the frame 10 and are located at the upper part of the frame 10, and the gripping portion 22 and the handheld portion 12 are located at the lower part of the frame 10.

[0040] As one of the implementation manners, the pin extractor and installer further includes a movable rod 60 and a check mechanism. The movable rod 60 is movably inserted through the frame 10. One end of the movable rod 60 is fixed to the sliding member 30. The placement position 11 and the movable rod 60 are respectively located on opposite sides of the sliding member 30. Both the movable rod 60 and the sliding member 30 can move along the length direction of the frame 10. The check mechanism is configured to prevent the movable rod 60 from moving in the direction away from the placement position 11. The check mechanism further includes a pressing portion, and the pressing portion is configured to allow the check mechanism to allow the movable rod 60 to move in the direction away from the placement position 11 when being pressed.

[0041] Further, the pushing block 40 is sleeved on the movable rod 60 and can move along the length direction of the movable rod 60; of course, the pushing block 40 can also be slidably installed on the frame 10.

[0042] Further, during use, when the gripping portion 22 is gripped once, the sliding member 30 drives the pin seat 90 to move forward a certain distance. When gripped continuously for multiple times until the pin seat 90 reaches the end, when resetting is required, press the pressing portion of the check mechanism, and then the movable rod 60 drives the sliding member 30 to rebound and return to the original position, and then the gripping portion 22 can be gripped continuously again.

[0043] Further, the check mechanism includes a check piece 70 and a second elastic member 80. The upper end of the check piece 70 is fixed to the frame 10, and the lower end forms a pressing portion 71. A through hole is provided on the check piece 70, and the movable rod 60 passes through the through hole. The second elastic member 80 is located between the frame 10 and the check piece 70. The second elastic member 80 is used to provide an elastic force to incline the check piece 70 outward, so that the side wall of the through hole presses against the movable rod 60, thereby increasing the frictional force and preventing the movable rod 60 from rebounding. When the pressing portion 71 is pressed, the side wall of the through hole leaves the movable rod 60, so that the movable rod 60 can move relative to the check piece 70, realizing the rebound, and driving the sliding member 30 to move back, realizing the reset. As one implementation manner, the second elastic member 80 may be a spring.

[0044] Further, in order to enable the sliding member 30 to reset better, the pin extractor further includes a third spring 130. The third spring 130 is disposed between the fixed seat 15 and the sliding member 30 and is used to provide a resilience force to move the sliding member 30 away when the sliding member 30 moves in the direction close to the fixed seat 15.

[0045] Further, from the perspective of the length direction of the frame 10, the movable rod 60 sequentially passes through the check piece 70, the second elastic member 80, the pushing block 40, and the first elastic member 50, and then is fixedly connected to the sliding member 30, wherein the movable rod 60 can move relative to the pushing block 40.

[0046] As one implementation manner, an installation cavity is provided in the sliding member 30, the pin seat 90 is installed in the installation cavity, and a groove 31 communicating with the installation cavity is further provided on the outer side of the sliding member 30. A handle 97 is installed on the pin seat 90, and the handle 97 extends out of the groove 31. The handle 97 is used to drive the pin seat 90 to rotate relative to the sliding member 30 when moving in the extending direction of the groove 31, so as to realize the position adjustment of the pin seat 90, so that the pin in the pin installation groove 92 or the pin extractor 100 in the pin extractor installation hole 91 corresponds to the pin hole position on the vehicle key 120 respectively.

[0047] In a preferred implementation manner, when the handle 97 rotates to the topmost position, the pin extractor 100 in the pin extractor installation hole 91 corresponds to the pin hole position on the vehicle key 120; when the handle 97 rotates to the lowermost position, the pin in the pin installation groove 92 corresponds to the pin hole position on the vehicle key 120; this can avoid the handle horizontally affecting the operation in the middle position. Of course, it is also possible that when the handle 97 rotates to the lowermost position, the pin extractor 100 in the pin extractor installation hole 91 corresponds to the pin hole position on the vehicle key 120; when the handle 97 rotates to the topmost position, the pin in the pin installation groove 92 corresponds to the pin hole position on the vehicle key 120.

[0048] Further, the width of the groove 31 can be made consistent with the diameter of the handle 97. In this way, the groove 31 can also limit the movement of the handle 97 in the length direction of the frame 10, so that the pin seat 90 will not shake during movement and is more stable.

[0049] As one of the implementation manners, the pin and the dowel pin should be installed on different planes.

[0050] Please refer to Figure 4 , further, one end of the pin seat 90 close to the placement position 11 has a first end face 93 and a second end face 94, and the first end face 93 and the second end face 94 are arranged in a stepped manner. The pin extraction hole 91 and the dowel pin installation groove 92 are respectively arranged on the first end face 93 and the second end face 94. Specifically, the pin extraction hole 91 is opened inward from the first end face 93, and the dowel pin installation groove 92 is arranged on the side of the pin seat 90, and one end of the dowel pin installation groove 92 forms an opening on the second end face 94.

[0051] As one of the implementation manners, a first positioning hole 96 is further provided on the pin seat 90, and a second positioning hole and a third positioning hole are provided on the sliding member 30. The second positioning hole and the third positioning hole are both used to align with the first positioning hole 96 after the position of the pin seat 90 is adjusted. During work, the position of the pin seat 90 is adjusted by rotation to align the pin or the dowel pin with the pin position of the vehicle key 120. Then, a positioning pin is inserted into the first positioning hole 96 and the second positioning hole (or the first positioning hole 96 and the third positioning hole) to realize the positioning of the pin seat 90. In this way, the pin seat 90 is more stable when extracting or installing the pin.

[0052] As one of the implementation manners, in the pin extraction and installation device of the present invention, one end of the pin seat 90 close to the placement position 11 may be provided with only the pin extraction hole 91 or only the dowel pin installation groove 92, so as to simply realize the function of extracting the dowel pin or simply realize the function of installing the dowel pin.

[0053] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of the present invention by the same token.
