[0002] A screw is a tool that uses the physical and mathematical principles of the inclined plane circle rotation and friction of an object to gradually fasten the machine parts of an object. A screw is a general term for fasteners and is an everyday colloquialism. Screws are indispensable industrial necessities in daily life: such as extremely small screws used in cameras, glasses, watches, electronics, etc.; general screws for televisions, electrical products, musical instruments, furniture, etc.; for engineering, construction, and bridges, large screws and nuts are used; for transportation tools, airplanes, trams, cars, etc., large and small screws are used together.

By setting a threaded rod and a pointed screw, the worker can turn the handle. Finally, after the tip of the pointed screw rod penetrates into the faulty screw, the worker can take out the insertion rod at this time, so that the connection between the connecting piece and the support rod is lost. Then continue to turn the handle to take out the faulty screw from the inside of the mounting plate, so as to achieve the effect of quickly removing the faulty screw, which is convenient for the worker to remove the faulty screw, so as to solve the problems raised in the above background art.

Detailed Embodiment

[0016] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0017] Embodiment 1: Referring to the attached Figure 1-2 description, a device for removing a faulty screw of the present utility model includes a connecting member 1, as detailed in Figure 2 , a threaded rod 2 is connected inside the connecting member 1 by threads. A handle 3 is fixedly connected to the top of the threaded rod 2, and a sleeve 4 is fixedly connected to the bottom of the threaded rod 2. A bidirectional threaded rod 5 is connected inside the sleeve 4 by threads. Two clamping blocks 6 are connected to the outer wall of the bidirectional threaded rod 5 by threads. The two clamping blocks 6 are slidably connected inside the sleeve 4. A pointed screw rod 7 is arranged between the two clamping blocks 6. The pointed screw rod 7 is inserted into the sleeve 4. A support rod 8 is inserted into the bottom of the connecting member 1. A plug rod 9 is connected inside the support rod 8 by threads. The plug rod 9 is inserted into the connecting member 1;

[0018] The bottom of the support rod 8 is rotatably connected to a rotating member 10. A nut 11 is arranged on the top of the rotating member 10. A clamping member 12 is connected inside the nut 11 by threads. The clamping member 12 is inserted into the rotating member 10. An installation plate 13 is arranged at the bottom of the rotating member 10. The installation plate 13 is arranged on the top of the clamping member 12. A faulty screw 14 is connected inside the installation plate 13 by threads. The faulty screw 14 is arranged at the bottom of the pointed screw rod 7.

[0019] It should be noted that, when the staff needs to remove the faulty screw 14, first insert the rotating member 10 of appropriate size between the two clamping blocks 6 inside the sleeve 4, and then rotate the bidirectional threaded rod 5, so that the bidirectional threaded rod 5 drives the two clamping blocks 6 to approach each other to clamp and fix the pointed screw rod 7, so as to achieve the effect of clamping and fixing the pointed screw rods 7 of different sizes, which is convenient for the staff to replace the pointed screw rods 7 to remove the faulty screws 14 of different sizes, and then the staff can align the pointed screw rod 7 with the top of the faulty screw 14 and rotate the rotating member 10 to At a suitable position on the mounting plate 13, move the nut 11 and the clamping member 12 to the side of the mounting plate 13, and rotate the nut 11, so that the nut 11 drives the clamping member 12 to rise through the thread, and then the clamping member 12 rises to cooperate with the rotating member 10 to clamp and fix the mounting plate 13, so that the removal device is fixed at this position as a whole, and the pointed screw rod 7 is fixed on the top of the faulty screw 14, so as to achieve the effect of quickly fixing and limiting the pointed screw rod 7, and prevent the pointed screw rod 7 from deviating when entering the interior of the faulty screw 14, so that the pointed screw rod 7 cannot enter the interior of the faulty screw 14;

[0020] Furthermore, when the staff has fixed the removal device, the staff can turn the handle 3 so that the handle 3 drives the threaded rod 2 to rotate and descend along the thread inside the connecting piece 1, and then the threaded rod 2 drives the fixed pointed screw rod 7 to rotate and descend through the clamping block 6 inside the sleeve 4, so that the threaded tip of the pointed screw rod 7 strikes into the interior of the faulty screw 14. When the tip of the pointed screw rod 7 strikes into the interior of the faulty screw 14, the staff can take out the insertion rod 9 from the inside of the support rod 8 and the connecting piece 1, so that the connection between the connecting piece 1 and the support rod 8 is lost. At this time, the staff continues to turn the handle 3, and finally the pointed screw rod 7 continues to strike into the interior of the faulty screw 14. Due to the faulty screw 14 and the installation screw The threaded connection resistance of the mounting plate 13 is less than the resistance of the pointed screw rod 7 entering the faulty screw 14. The pointed screw rod 7 will drive the faulty screw 14 to rotate, causing the faulty screw 14 to rotate and rise and disengage from the inside of the mounting plate 13, so as to achieve the effect of quickly removing the faulty screw 14, making it convenient for the staff to remove the faulty screw 14 and prevent the faulty screw 14 from breaking inside the mounting plate 13, thereby affecting the installation and fixation of the mounting plate 13. It should be noted that when the pointed screw rod 7 drives the faulty screw 14 to disengage from the inside of the mounting plate 13, it will rise, causing the pointed screw rod 7 to push the threaded rod 2 to rise through the clamping block 6 and the sleeve 4, thereby causing the threaded rod 2 to drive the connecting piece 1 to rise and partially disengage from the inside of the support rod 8.
