The left and right ends of the toggle block 661 are fixedly connected to a shaft rod 662 that passes through the channel 64 and is rotatably connected to the slide groove 65. The outer side of one end of the shaft rod 662 away from the toggle block 661 is fixedly connected to a group of four ridges 663 set at equal angles. The outer side of one end of the shaft rod 662 in the slide groove 65 is sleeved with a sleeve block 67 that is slidably connected to a group of ridges 663. The outer side of one end of the shaft rod 662 in the slide groove 65 is sleeved with a first spring 68. The lifting module 7 includes a connecting rod 7 fixed on the upper side of the sleeve block 67. When the locking cam 721 is in the unlocking state, the locking cam 722 is unlocked, and the locking cam 723 is unlocked, so that the locking cam 723 can be unlocked. When the locking cam 723 is unlocked, the locking cam 723 is unlocked, and the locking cam 723 is unlocked. When the locking cam 723 is in the unlocking state, the locking cam 723 is unlocked, and the locking cam 723 is unlocked.The front side of one end of the connecting rod 733 away from the pushing bar 731 is fixedly connected to a stop block 734, and the side lifting portion 72 is installed with an auxiliary lifting portion 74. The auxiliary lifting portion 74 includes a group of two auxiliary lifting guide bars 741 slidably connected to the groove 722, and one end of the auxiliary lifting guide bar 741 away from the side lifting guide bar 721 is fixedly connected to a connecting plate 742. A notch 743 is provided on the rear side of the connecting plate 742, and an elastic pull rope 75 is fixedly connected between the connecting plate 742 and the outer end surface of the side lifting guide bar 721. Through this arrangement, the adjustment portion 5 can adjust the position of the adjustment transmission portion 6 and the lifting module 7, and the adjustment transmission portion 6 can control the lifting module 7 to rotate backward so that the lifting module 7 is between the socket printed circuit board 21 and the plug printed circuit board 23. At the same time, the guide part 4 can be pushed upward by the rotating top piece 12, so that the adjustment part 5, the adjustment transmission part 6, and the lifting module 7 can be moved vertically upward at the same time, so that the auxiliary lifting guide bar 741 cooperates with the side lifting guide bar 721 to move vertically upward to lift the plug printed circuit board 23, so that the plug printed circuit board 23 drives the plug connector 24 to move vertically upward and disengage from the connection with the socket connector 22; the clamping part 3 includes a folding plate 31 slidably connected to the rail groove 13, and a tension spring 32 is fixedly connected between the end of the folding plate 31 close to the rotating top piece 12 and the inner wall of the rail groove 13. Through this arrangement, the tension spring 32 can reset the folding plate 31 that moves outward, and a rotating part 36 is rotatably connected in the hole position on the lower side of the folding plate 31. The upper end of the rotating part 36 is fixedly connected to the screw rod 35, and the outer side of the screw rod 35 is spirally connected The upper end of the adjusting plate 33 is fixedly connected to the upper side of the socket printed circuit board 21, and the upper and lower positions of the adjusting plate 33 and the positioning guide block 34 are adjusted by the rotation of the rotating member 36 through the screw rod 35. The upper and lower positions of the positioning guide block 34 are adjusted. The guide surface of the positioning guide block 34 is set on the upper side. When the positioning guide block 34 is pushed from the bottom to the top, the contact between the positioning guide block 34 and the socket printed circuit board 21 is caused by the setting of the guide surface, so that the positioning guide block 34 is pressed to the side away from the socket printed circuit board 21, so that the positioning guide block 34 can pass over the socket printed circuit board 21. The spacing between the positioning guide block 34 and the base 11 is the same as the thickness of the socket printed circuit board 21. Similarly, the socket printed circuit board 21 is arranged between the positioning guide block 34 and the base 11. Through this arrangement, the positioning guide block 34 and the base 11 can clamp the socket printed circuit board 21; the rear side of the sleeve block 67 is composed of a lower curved surface and an upper plane. Through this arrangement, the sleeve block 67 can only rotate backward 90 degrees. The inner hole position of the sleeve block 67 is composed of a middle hole and a concave hole groove arranged around the outer side of the middle hole. Through this arrangement, the rotation of the toggle rod 66 can drive the sleeve block 67 to rotate through the convex strip 663. The sleeve blocks 67 are all arranged on the inner side of the slide groove 65. The first springs 68 are all arranged at the left and right sides of a group of sleeve blocks 67. Through this arrangement, the first spring 68 can reset the sleeve block 67 after displacement. The first spring 68 and the second spring 732 are both low-rigidity soft springs.Through this setting, the first spring 68 has limited interference with the rotation of the lifting modules 7 on both sides, so that the pressure exerted on the plug printed circuit board 23 by the lifting modules 7 on both sides after rotation is limited, avoiding damage to the plug printed circuit board 23 after the lifting module 7 rotates backward, making the elastic force of the second spring 732 smaller and not affecting the squeezing of the plug printed circuit board 23 on the push strip 731. The elasticity of the first spring 68 is greater than the elasticity of the second spring 732. Through this setting, the first spring 68 will not be affected by the second spring 732 when resetting the sleeve block 67 and the lifting module 7. The interference of the push bar 731 and the push bar 731, the lower side of the rotating groove 62 is provided with a slot 63 on the lower side of the toggle block 661, and the slot 63 is provided to facilitate the user to detent the toggle block 661; the front end of the push bar 731 is provided with a bevel, and the front end of the push bar 731 is exposed from the sinking groove 723. Through this setting, after the side lifting portion 72 is rotated backward, the push bar 731 will be pressed into the sinking groove 723 by the plug printed circuit board 23, and the width of the sliding channel 724 is greater than the diameter of the connecting rod 733. The rear curved surface of the connecting rod 733 and the sliding channel When the locking cam 731 is unlocked, the locking cam 732 is unlocked, and the winch 720 is unlocked, so that the winch 720 can be unlocked easily. The curved surface of the end of the lifting guide bar 741 near the cover module 8 is the same as the curved surface of the side lifting guide bar 721. This arrangement prevents the auxiliary lifting guide bar 741 from affecting the guiding displacement of the side lifting guide bar 721. The guiding curved surface of the side lifting guide bar 721 is located at the rear. The lifting modules 7 are located on the left and right sides of the plug connector 24. The lifting modules 7 are aligned front to back with the ends of the plug printed circuit board 23. This arrangement ensures that the side lifting portions 72 of the rotating lifting modules 7 contact the ends of the plug printed circuit board 23.

[0042] like Figure 1 、 Figure 6 、 Figure 20-23As shown, the covering module 8 is installed on the upper side of the adjusting transmission part 6, and the covering module 8 includes a folding rod 81 fixed to the front side of the toggle block 661 and arranged vertically in the longitudinal direction, the upper end of the folding rod 81 is fixedly connected to a rail sleeve 82 that passes through the front and rear, and the inner side of the rail sleeve 82 is slidably connected to a rail rod 83, the front end of the rail rod 83 is fixedly connected to a counterweight block 84 on the front side of the rail sleeve 82, and the rear end of the rail rod 83 is fixedly connected to a cover plate 85 on the front side of the electrical connection part 2, and the rear side of the cover plate 85 is fixedly connected to an elastic pad 86, and a cleaning part 87 is installed on the cover plate 85, and the cleaning part 87 includes a side rail shell 871 fixed to the upper side of the cover plate 85 and arranged horizontally, and the inner side of the side rail shell 871 is movably connected to a rail block 872, and the upper side of the rail block 872 is fixedly connected There is an adjusting arm 873 that fits with the upper end surface of the side rail shell 871, and the lower side of the front end of the adjusting arm 873 is rotatably connected to a rotating shaft 874 set vertically in the longitudinal direction. The outer side of the rotating shaft 874 is fixedly connected to a tearable adhesive roller 875 that fits with the front end surface of the cover plate 85. Through this arrangement, the cover module 8 will rotate after the toggle rod 66 of the adjustment transmission part 6 is rotated. When the plug connector 24 moves up and disengages from the connection with the socket connector 22, and then moves it from the lower side of the cover plate 85, the weight of the counterweight block 84 drives the rail rod 83, the cover plate 85 and the elastic pad 86 to move downward to cover the socket connector 22, so as to prevent dust from falling into the socket connector 22 after the socket connector 22 is separated from the plug connector 24, and cleaning The part 87 can rotate the adjusting arm 873 180 degrees to move the rotating shaft 874 and the tearable adhesive roller 875 to the rear side, so that the tearable adhesive roller 875 is in contact with the elastic pad 86. At this time, the adjusting arm 873 can be moved horizontally to drive the tearable adhesive roller 875 to rotate on the surface of the elastic pad 86, and the dust on the surface of the elastic pad 86 is cleaned by the tearable adhesive roller 875. After cleaning, the tearable adhesive roller 875 can be reset to complete the cleaning of the elastic pad 86. The track sleeve 82 is a square groove structure, and the track rod 83 is a square rod structure. Through this arrangement, the track rod 83 can only be translated, but cannot be rotated in the track sleeve 82, so that the cover plate 85 cannot rotate with the track rod 83 as the center point, and the elastic pad 86 The side length is the same as the side length of the cover 85, and the side length of the elastic pad 86 is larger than the side length of the socket connector 22. Through this arrangement, the elastic pad 86 can completely cover the socket connector 22. The track block 872 consists of a lower circular rotating block and an upper circular connecting block. The diameter of the lower circular rotating block of the track block 872 is the same as the inner rail width of the side rail shell 871. Through this arrangement, the track block 872 can be stably translated in the side rail shell 871. The tearable adhesive roller 875 consists of an inner roller and an outer tearable adhesive paper. Through this arrangement, the tearable adhesive roller 875 can adhere to dust, and when there is too much dust on the surface, the outermost layer of adhesive paper can be torn off and the inner layer of new adhesive paper can be used for subsequent cleaning.

[0043] Working process: The operation of the auxiliary separation tool for separating high-density low-profile connectors is as follows. It should be noted that the auxiliary separation tool of this solution can be held in one hand by the user and is easy to carry; for installation operation, first, the screw rod 35 is driven to rotate by rotating the rotating member 36, and the adjustment plate 33 connected thereto is driven to move up and down by the rotation of the screw rod 35, thereby adjusting the up and down position of the positioning guide block 34, so as to adjust the distance between the positioning guide block 34 and the base 11, so that the distance size between the positioning guide block 34 and the base 11 is roughly the same as the thickness size of the socket printed circuit board 21, at this time, the seat part 1 is pushed toward the direction of the socket printed circuit board 21, and the positioning guide blocks 34 of the clamping parts 3 on both sides that move with the seat part 1 will first contact the socket printed circuit board 21, and under the influence of the upward thrust, the positioning guide blocks 34 on both sides will drive the adjustment plate 33 and the folding plate 31 connected thereto. The lower side of the socket printed circuit board 21 moves backward, and at the same time, the tension spring 32 changes from a contracted state to an extended state. When the positioning guide block 34 passes over the socket printed circuit board 21, the tension springs 32 on both sides return to their original state and contract, driving the two side folding plates 31, the adjustment plates 33 and the positioning guide blocks 34 connected thereto to return to their original state, so that the socket printed circuit board 21 is between the positioning guide blocks 34 and the base 11. At this time, the clamping tightness of the base 11 and the positioning guide blocks 34 on the socket printed circuit board 21 can be adjusted by the rotating member 36. Through the above operation, the tooling can be quickly installed on the socket printed circuit board 21. After installation, the position of the adjustment transmission part 6 can be adjusted by sliding the sliding guide plate 51 and the rail rod 52 of the sliding adjustment part 5, so that the lifting modules 7 on both sides can be aligned front and back with the two ends of the plug printed circuit board 23, and the covering module 8 can be aligned front and back with the socket connector 22.To prepare for the lifting and separation operation, place your finger in the slot 63 and pull the toggle block 661 of the toggle rod 66 to rotate it, so that the two side shafts 662 and the ridges 663 connected thereto rotate, thereby driving the sleeve blocks 67 on both sides to rotate, so that the rear plane of the sleeve block 67 fits with the lower inner wall of the slide groove 65 after rotating backward, so that the sleeve block 67 can only rotate backward 90 degrees, so that the lifting modules 7 on both sides connected to the sleeve block 67 rotate backward 90 degrees. During the rotation process, the side lifting portion 72 of the lifting module 7 will first contact the plug printed circuit board 23. The two ends are in contact, and under the influence of the rotational force, the side lifting guide strips 721 on both sides are guided by the rear curved surface and move backward at the two ends of the upper side of the plug printed circuit board 23, and the backward movement of the lifting modules 7 on both sides will cause the first springs 68 on both sides to contract through the sleeve block 67 (because the first spring 68 is a low-rigidity soft spring, the first spring 68 has limited interference with the rotation of the lifting modules 7 on both sides, so that the pressure exerted by the lifting modules 7 on the plug printed circuit board 23 is limited, avoiding damage to the plug printed circuit board 23 after the lifting modules 7 rotate backward), until the two sides are When the side lifting guide bar 721 is pressed downward and turned over the plug printed circuit board 23, the first springs 68 on both sides will expand and reset to push the sleeve blocks 67 and the lifting module 7 on both sides to move toward each other, so that the side lifting guide bars 721 on both sides move toward the plug connector 24, so that the displaced side lifting guide bars 721 are located at the lower sides of the two ends of the plug printed circuit board 23. During the displacement of the side lifting guide bar 721, the push bar 731 protruding from the sinking groove 723 will be squeezed by the plug printed circuit board 23, so that the push bar 731 moves deeper into the sinking groove 723 to press the second spring 73 2 is squeezed, and the displacement of the push bar 731 will drive the displacement of the connecting rod 733 and the block 734, so that the block 734 is separated from the contact with the connecting plate 742 and aligned with the notch 743. Without the resistance of the block 734 to the connecting plate 742 of the auxiliary lifting portion 74, the elastic pull rope 75 can be contracted to pull the auxiliary lifting portion 74 toward the plug connector 24, so that the auxiliary lifting guide bar 741 is moved to the lower side of the two ends of the plug printed circuit board 23, and can be used as an extension of the side lifting guide bar 721 on both sides to assist in lifting, completing the preparation operation for lifting and separation (such as; Figure 23As shown); Covering preparation operation, by rotating the adjustment arm 873 180 degrees, the rotating shaft 874 and the tearable adhesive roller 875 can be moved to the rear side, so that the tearable adhesive roller 875 is in contact with the elastic pad 86. At this time, the adjustment arm 873 can be translated to drive the tearable adhesive roller 875 to rotate on the surface of the elastic pad 86, and the tearable adhesive roller 875 is used to adhere and clean the dust on the surface of the elastic pad 86. After cleaning, the tearable adhesive roller 875 can be reset to complete the cleaning of the elastic pad 86. The toggle block 661 is rotated 90 After the degree of rotation, the covering module 8 will be driven to press and rotate backward, so that the folding rod 81 in the vertical state becomes a horizontal state, and the rail rod 83 in the horizontal state becomes a vertical state, so that the counterweight block 84 and the cover plate 85 in the front and rear position relationship change to an up-down position relationship, so that the cover plate 85 and the elastic pad 86 are on the upper side of the plug printed circuit board 23, completing the preparation operation of covering; lifting and separating operation, the pressure guide part 4 is pushed up by rotating the top member 12, and the upward movement of the pressure guide part 4 causes the adjustment part 5, the adjustment transmission part 6, and the lifting module 7 to move vertically upward at the same time, so that the auxiliary lifting guide bar 741 cooperates with the auxiliary lifting guide bar 741 to move upward. The side lifting guide bar 721 moves vertically upward to lift the plug printed circuit board 23, so that the plug printed circuit board 23 drives the plug connector 24 to move vertically upward to separate from the socket connector 22, so that the portable auxiliary separation tool can conveniently and quickly separate the socket connector 22 and the plug connector 24 of the high-density low-profile connector vertically, avoiding product damage caused by manual direct separation; in the covering operation, the pressure guide part 4 drives the adjustment transmission part 6 to move upward and also drives the covering module 8 to move upward. When the plug connector 24 moves upward and separates from the socket connector 22, After it is removed from the lower side of the cover plate 85, the weight of the counterweight block 84 drives the rail rod 83, the cover plate 85 and the elastic pad 86 to move downward to cover the socket connector 22, so as to prevent dust from falling into the socket connector 22 after the socket connector 22 is separated from the plug connector 24. When the portable auxiliary separation tool is used to separate the socket connector 22 and the plug connector 24 of the high-density low-profile connector, it can automatically block and cover the socket connector 22 that is prone to dust, so as to prevent the dust falling into the socket connector 22 from affecting the subsequent connection test.
