DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] In order to solve the technical problem that the existing spiral ratchet screw driver has no automatic nailing function, Figure 1-6 As shown, the following preferred technical solutions are provided:

[0027] A spiral ratchet screw driver with an automatic nailing function comprises a driver body 1, an output end at the top left side of the driver body 1 is fixedly connected with a sleeve head 2, a surface of the sleeve head 2 is sleeved with a first spring 3 and a cover plate 4 in sequence from left to right, a fixed cylinder 5 is sleeved on the left side of the cover plate 4, an elastic sheet 6 is fixedly connected to the left side of the inner wall of the fixed cylinder 5, an infrared sensor 7 is fixedly connected to the bottom of the inner cavity of the fixed cylinder 5, a conveying pipe 8 is connected to the top of the fixed cylinder 5, a second spring 9 is fixedly connected to the top of the inner cavity of the conveying pipe 8, a push plate 10 is fixedly connected to the bottom of the second spring 9, a plectrum 11 is fixedly connected to the left side of the push plate 10, the left side of the plectrum 11 penetrates to the outside of the conveying pipe 8, a feed port 12 is provided on the right side of the conveying pipe 8, an electromagnet 13 is fixedly connected to the bottom of the surface of the conveying pipe 8, a limiting sleeve 14 is fixedly connected to the top of the driver body 1, a limiting rod 15 is provided in the inner cavity of the limiting sleeve 14, and the left side of the limiting rod 15 is fixedly connected to the conveying pipe 8.

[0028] Specifically, the obliquely arranged feed port 12 can facilitate the staff to insert the bolts one by one into the inner cavity of the conveying tube 8, and store the bolts through the conveying tube 8. When nailing is needed, the infrared sensor 7 is used to detect the inside of the fixed tube 5. When no bolt is detected, the electromagnet 13 is closed, and the second spring 9 is reset to enable the push plate 10 to push the bolt to move, and the bolt inside the conveying tube 8 is pushed into the fixed tube 5. The bolt is positioned by four elastic sheets 6 so that the bolt is located on the left side of the sleeve head 2. The push plate 10 can be pushed to the top of the inner cavity of the conveying tube 8 by the paddle 11. The positioning notch 16 can cooperate with the paddle 11 to lock the push plate 10, so that the staff can insert the bolt into the conveying tube 8 through the feed port 12. The fixed tube 5 can be limited by the limit sleeve 14 and the limit rod 15 to prevent it from rotating with the sleeve head 2.

[0029] In order to solve the technical problem that the fixed cylinder 5 is easy to rotate with the sleeve head 2 and the push plate 10 cannot be positioned, as shown in FIG. Figure 1 , Figure 2 and Figure 6 As shown, the following preferred technical solutions are provided:

[0030] The surface of the limiting rod 15 is slidably connected to the inner wall of the limiting sleeve 14 , and an observation opening is opened on the left side of the fixing tube 5 .

[0031] There are four elastic sheets 6 , which are evenly distributed in the inner cavity of the fixing tube 5 . The elastic sheets 6 are made of high-elastic steel sheet material.

[0032] A movable opening for use with the paddle 11 is provided on the left side of the delivery tube 8 , and a positioning notch 16 for use with the paddle 11 is provided on the top of the left side of the delivery tube 8 .

[0033] The top and bottom of the paddle 11 are fixedly connected with anti-skid pads, and the top and bottom of the second spring 9 are fixedly connected to the inner wall of the delivery pipe 8 and the push plate 10 respectively.

[0034] Specifically, the limiting rod 15 and the limiting sleeve 14 can limit the fixed tube 5 so that it can only move left and right, and prevent it from rotating with the sleeve head 2. The observation opening can facilitate the staff to observe whether the bolt is located between the four elastic sheets 6. The elastic sheet 6 made of high-elastic steel sheets can be deformed after being squeezed, and will not affect the installation of the bolt by the sleeve head 2. The movable opening can facilitate the movement of the paddle 11. The positioning notch 16 can cooperate with the paddle 11 to lock the push plate 10. The anti-slip pad can increase the anti-slip effect of the paddle 11 and prevent the staff from slipping and losing their hands when pushing the paddle 11.

[0035] In order to solve the technical problems that the bolts are not convenient to be inserted vertically into the delivery pipe 8 and the fixing tube 5 is not convenient to be disassembled, as Figure 1 , Figure 3 and Figure 4 As shown, the following preferred technical solutions are provided:

[0036] There are six electromagnets 13 , which are evenly distributed at the bottom of the surface of the delivery tube 8 , and one side of the electromagnet 13 penetrates into the inner cavity of the delivery tube 8 .

[0037] The right side of the inner cavity of the fixing tube 5 is fixedly connected to the cover plate 4 by means of threads, and a limiting groove for use with the bolt is provided at the bottom of the push plate 10 .

[0038] The bottom of the delivery pipe 8 is a hollow cone, and the feed port 12 is arranged obliquely.

[0039] A through hole for use with the sleeve head 2 is provided on the right side of the cover plate 4 , and the inner diameter of the through hole is larger than the diameter of the connecting rod of the sleeve head 2 .

[0040] Specifically, the electromagnet 13 can position the bolts inside the delivery tube 8 to prevent multiple bolts from entering the fixed tube 5 at the same time, which would cause the fixed tube 5 to get stuck. The provision of an electromagnet 13 can increase the positioning effect of the bolts. The threaded cover plate 4 can facilitate the staff to disassemble the fixed tube 5, so that the screwdriver body 1 can complete the fixing of the bolts in a narrow area. The limiting groove can limit the bolts so that the bolts can be smoothly pushed into the inner cavity of the fixed tube 5 by the push plate 10. The hollow cone at the bottom of the delivery tube 8 can limit the bolts so that they can accurately enter the inner cavity of the fixed tube 5. The obliquely arranged feed port 12 can facilitate the staff to insert the bolts into the delivery tube 8 one by one, to prevent the bolts from getting stuck after being laterally inserted into the delivery tube 8. The through hole can facilitate the sleeve head 2 to move up and down, so that the sleeve head 2 can fix the bolts.

[0041] Working principle: When in use, the staff pushes the paddle 11 and pushes the paddle 11 into the positioning notch 16 to lock the push plate 10. Then the staff inserts the bolts into the conveying tube 8 one by one through the feed port 12. Since the feed port 12 is opened obliquely, the bolts are prevented from getting stuck when they are inserted into the conveying tube 8. Then the paddle 11 is pushed so that the paddle 11 is located in the movable port. After the bolts are stored, the infrared sensor 7 is turned on. The interior of the fixed tube 5 is detected through the infrared sensor 7. When it is detected that there is no bolt in the fixed tube 5, the electromagnet 13 is closed. At this time, the second spring 9 is reset to drive the push plate 10 to move. The push plate 10 moves to push the bolts into the inner cavity of the fixed tube 5. At the same time, the electromagnet 13 is started again to position the bolts in the conveying tube 8. After the bolts enter the fixed tube 5, four elastic sheets 6 are used. After the screwdriver body 1 is tightened, the screwdriver body 1 is tightened, and the sleeve head 2 is moved to cover the bolt and squeeze the four elastic sheets 6. The screwdriver body 1 is opened, and the sleeve head 2 is driven by the screwdriver body 1 to rotate, and the installation and fixation of the bolt are completed. Then, the fixing cylinder 5 is no longer squeezed, and the first spring 3 is reset to reset the sleeve head 2. At this time, there is no bolt inside the fixing cylinder 5. After the infrared sensor 7 is used again to detect, the electromagnet 13 is turned off and the bolt is nailed again. The whole process is fast and convenient, and there is no need for manual nailing by the staff. During high-altitude operations, the situation of falling objects from high altitude due to loose bolts can be avoided, thereby increasing safety.

[0042] To sum up: the spiral ratchet screw driver with automatic nailing function solves the problem that the existing spiral ratchet screw driver has no automatic nailing function through the coordinated use of the socket head 2, the first spring 3, the cover plate 4, the fixing tube 5, the elastic sheet 6, the infrared sensor 7, the conveying tube 8, the second spring 9, the push plate 10, the paddle 11, the feed port 12, the electromagnet 13, the limit sleeve 14 and the limit rod 15.
