Description

Technical Field

[0001] The utility model relates to the field of screw removal, in particular to a screw removal device. Background Art

[0002] Screws are widely used. During use, the straight or cross pattern of the nut may easily slip due to unexpected circumstances. Without the assistance of the pattern groove inside the nut, how to remove the screw embedded in the screw hole becomes a very difficult problem. The current device for removing slipped screws mainly uses a drill bit to drill a hole in the nut, and then uses a reverse tap to remove it.

[0003] Traditional screw removal devices still have certain shortcomings during use: when drilling with a drill bit, the current removal device is prone to causing the drill hole to be skewed or offset due to unstable hands, which in turn leads to removal failure. Secondly, when drilling, the metal wire inside the nut will splash out. Although there is currently a structure that adds a transparent cover to the outside of the nut, the inner wall of the cover is easily stained with debris after being hit by metal debris and its inner surface is easily scratched after long-term use. The current cover structure is not convenient for users to clean or quickly replace it.

[0004] Therefore, it is necessary to provide a new screw removal device to solve the above technical problems. Utility Model Content

[0005] The technical problem solved by the utility model is to provide a screw removal device which can effectively prevent structural instability during drilling and is convenient for cleaning and replacing the cover structure.

[0006] In order to solve the above technical problems, the utility model provides a screw removal device comprising: a shielding assembly, a positioning assembly and a first limiting member, the positioning assembly comprising a fixing member, a first clamping block being fixedly connected to a side wall surface of the fixing member, the first clamping block being clamped with the first limiting member, a guide rail being fixedly connected to a side wall surface of the fixing member relative to the first clamping block, a slider being slidably connected to the surface of the guide rail, the slider being fixedly connected to a driving motor via a connecting block, the output end of the driving motor being fixedly connected to a connecting member, and a spring being fixedly connected between the slider and the fixing member;

[0007] The shielding assembly includes a mounting plate, which is fixedly connected to one end of a fixing member. Brackets are vertically arranged at the four corners of a side surface of the mounting plate relative to the driving motor. The ends of the brackets are fixedly connected to supporting feet. A slot is provided on the surface of the bracket, and a partition is inserted between the slots of two adjacent brackets. A through opening is provided on the surface of the mounting plate, and the connecting member is located on the inner side of the through opening.

[0008] As a further solution of the present invention, the end of the connecting member is fixedly connected to a second limiting member, a second clamping block is inserted into the interior of the second limiting member, and the two ends of the second clamping block are respectively fixedly connected to a drill bit and a reverse tap.

[0009] Through the above technical solution, the driving motor is first used to drive the drill bit to drill a hole in the nut, and then the direction of the second clamping block is adjusted to remove the screw through the reverse tap.

[0010] As a further solution of the present invention, a rotating sleeve is provided at a position on one side of the fixing member, the outer wall surface of the rotating sleeve is fixedly connected to a cantilever, the end of the cantilever is rotatably connected to a turntable, and the turntable is rotatably connected to the first limiting member.

[0011] Through the above technical solution, the rotating sleeve and the inner rod in the device are rotationally connected, and the first limiter and the turntable are also rotationally connected, so the driving motor and the drill bit can flexibly adjust the direction.

[0012] As a further solution of the present invention, the surfaces of the first limit member and the first clamping block are both provided with sockets, the two sockets are connected by a pin, and the surface of the connecting block between the slider and the drive motor is fixedly connected with a handle.

[0013] Through the above technical solution, in some cases, through the support of the inner rod and the cantilever, the user does not need to hold the drive motor and other structures all the time, which is more relaxed. In other cases, the inner rod and other structures hinder the user's operation. At this time, the pin can be pulled out to remove the fixing part, thereby facilitating its use.

[0014] As a further solution of the present invention, the inner side of the rotating sleeve is rotatably connected to an inner rod, the outer side of the inner rod is slidably connected to an outer rod, and a locking bolt is threadedly connected to the outer wall surface of one side of the outer rod, and the end of the locking bolt located inside the outer rod abuts against the surface of the inner rod.

[0015] With the above technical solution, the height of the rotating sleeve can be adjusted by the cooperation between the inner rod and the outer rod. After the adjustment is completed, the inner rod can be fixed with a locking bolt.

[0016] As a further solution of the present invention, the bottom of the outer rod is fixedly connected to a base, a plurality of universal wheels evenly distributed around the axis are installed on the surface of the base, and an armrest is fixedly connected to the outer wall of the outer rod located on the upper side of the base.

[0017] With the above technical solution, the user can flexibly adjust the position of the device through the cooperation of the universal wheels and the armrests.

[0018] As a further solution of the present invention, the first limiting member and the second limiting member are both located on the inner side of the four brackets, and a non-slip pad is bonded to a side wall surface of the support foot relative to the bracket.

[0019] Through the above technical solution, the metal wire inside the nut will splash out when drilling. Although there is a structure of adding a transparent cover on the outside of the nut, the inner wall of the cover is easily stained with debris after being hit by metal debris and its inner surface is easily scratched after long-term use. The current cover structure is not convenient for users to clean or replace it quickly. Therefore, the device sets the drill bit structure on the inner side of the four brackets, and the surfaces opposite to the brackets are provided with slots, and the partitions that play a shielding role are directly plugged into the slots. Therefore, the user can easily remove it from the bracket for cleaning, and it is also convenient to quickly replace the partitions. The structural design is humanized.

[0020] Compared with the related art, the screw removal device provided by the present invention has the following beneficial effects:

[0021] 1. In the present invention, when drilling, the metal wire inside the nut will splash out. Although there is a structure that adds a transparent cover to the outside of the nut, the inner wall of the cover is easily stained with debris after being hit by metal debris and its inner surface is easily scratched after long-term use. The current cover structure is not convenient for users to clean or replace it quickly. Therefore, the device arranges the drill bit structure on the inner side of the four brackets, and the surfaces opposite to the brackets are provided with slots, and the partition that plays a shielding role is directly plugged into the slot. Therefore, the user can easily remove it from the bracket for cleaning, and it is also convenient to quickly replace the partition. The structural design is humanized.

[0022] 2. In the present invention, the current extraction device is prone to causing the drill hole to be skewed or offset due to unstable hands when drilling with a drill bit, which in turn leads to extraction failure. In this device, the user can first place the four legs against the outside of the screw and align the drill bit with the nut. Due to the design of the anti-slip pad, the legs are not easy to offset. Then the user pushes the drive motor through the handle. Since a guide rail and slider structure are set on one side of the drive motor, the drive motor can move linearly along the guide rail. This can effectively assist the user in drilling holes in the nut and greatly reduce the possibility of failure. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The shielding assembly 6 includes a mounting plate, which is fixedly connected to one end of the fixing member 28. Brackets 8 are vertically arranged at the four corners of the surface of one side of the mounting plate relative to the driving motor 12. The end of the bracket 8 is fixedly connected to the support leg 10. A slot 17 is provided on the surface of the bracket 8. A partition 9 is inserted between the slots 17 of two adjacent brackets 8. A through opening 18 is provided on the surface of the mounting plate, and the connecting member 11 is located on the inner side of the through opening 18.

[0033] like Figure 1-4 As shown, the end of the connecting member 11 is fixedly connected to the second limiting member 23, the interior of the second limiting member 23 is plugged with a second clamping block 24, and the two ends of the second clamping block 24 are respectively fixedly connected to a drill bit 25 and a reverse tap 26.

[0034] First, the driving motor 12 is used to drive the drill bit 25 to drill a hole in the nut, and then the direction of the second clamping block 24 is adjusted, and the screw is removed by the reverse tap 26.

[0035] like Figure 1-4 As shown, a rotating sleeve 5 is provided on one side of the fixing member 28 , a cantilever is fixedly connected to the outer wall surface of the rotating sleeve 5 , a turntable is rotatably connected to the end of the cantilever, and the turntable is rotatably connected to the first limiting member 15 .

[0036] In the device, the rotating sleeve 5 is rotatably connected to the inner rod 2, and the first position-limiting member 15 is rotatably connected to the turntable, so that the driving motor 12 and the drill bit 25 can be flexibly adjusted in direction.

[0037] like Figure 1-4 As shown, the surfaces of the first limit member 15 and the first clamping block 16 are both provided with a socket 21 , the two sockets 21 are connected by a pin 14 , and a handle 20 is fixedly connected to the surface of the connecting block between the slider 27 and the drive motor 12 .

[0038] In some cases, with the support of the inner rod 2 and the cantilever, the user does not need to hold the drive motor 12 and other structures all the time, which is easier. In other cases, the inner rod 2 and other structures hinder the user's operation. At this time, the pin 14 can be pulled out to remove the fixing part 28, thereby facilitating its use.

[0039] like Figure 1-4 As shown, the inner side of the rotating sleeve 5 is rotatably connected to the inner rod 2, the outer side of the inner rod 2 is slidably connected to the outer rod 1, and the outer wall surface of one side of the outer rod 1 is threadedly connected to a locking bolt 3, and the end of the locking bolt 3 located inside the outer rod 1 abuts against the surface of the inner rod 2.

[0040] The height of the rotating sleeve 5 can be adjusted by the cooperation between the inner rod 2 and the outer rod 1. After the adjustment is completed, the inner rod 2 can be fixed by using the locking bolt 3.

[0044] When drilling, the metal wire inside the nut will splash out. Although there is a structure that adds a transparent cover to the outside of the nut, the inner wall of the cover is easily stained with debris after being hit by metal debris and its inner surface is easily scratched after long-term use. The current cover structure is not convenient for users to clean or quickly replace it. Therefore, the device sets the drill bit 25 structure on the inner side of the four brackets 8, and the surfaces opposite to the brackets 8 are provided with slots 17, and the partition 9 that plays a shielding role is directly plugged into the slot 17. Therefore, the user can easily remove it from the bracket 8 for cleaning, and it is also convenient to quickly replace the partition 9, and the structural design is humanized.

[0045] The working principle of a screw removal device provided by the utility model is as follows:

[0046] Step 1: When drilling, the metal wire inside the nut will splash out. Although there is a structure that adds a transparent cover to the outside of the nut, the inner wall of the cover is easily stained with debris after being hit by metal debris and its inner surface is easily scratched after long-term use. The current cover structure is not convenient for users to clean or quickly replace it. Therefore, the device arranges the drill bit 25 structure on the inner side of the four brackets 8, and the surfaces opposite to the brackets 8 are each provided with a slot 17, and the partition 9 that plays a shielding role is directly plugged into the slot 17. Therefore, the user can easily remove it from the bracket 8 for cleaning, and it is also convenient to quickly replace the partition 9, and the structural design is humanized;

[0047] Step 2: When drilling with the drill bit 25, the current removal device is prone to causing the drill hole to be skewed or offset due to unstable hands, which in turn leads to removal failure. In this device, the user can first place the four legs 10 against the outside of the screw and align the drill bit 25 with the nut. Due to the design of the anti-slip pad 19, the legs 10 are not easy to offset. Then the user pushes the drive motor 12 through the handle 20. Since the guide rail 13 and the slider 27 structure are set on one side of the drive motor 12, the drive motor 12 can move linearly along the guide rail 13, which can effectively assist the user in drilling holes in the nut and greatly reduce the possibility of failure.
