[0004] Based on the search of the above patents and the application of existing drilling structures with adjustable angles, it is understood that when the current drilling device is drilling, the positions of the rotating shaft and the drill bit are basically in the same straight line, and the lengths of the rotating shaft and the drill bit will also interfere with the required drilling position, making it inconvenient for the drill bit to directly drill the drilling area. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a drilling structure with adjustable angle to solve the problem that when drilling, the positions of the rotating shaft and the drill bit of the existing drilling device are basically in the same straight line, and the length of the rotating shaft and the drill bit will also interfere with the required drilling position, making it inconvenient for the drill bit to directly perform drilling operations on the drilling area.

[0006] The purpose and effect of the drilling structure capable of changing the angle of the utility model are achieved by the following specific technical means:

[0007] A drilling structure with adjustable angle comprises a fixed frame; a motor is fixedly connected to the rear end of the fixed frame, a rotating shaft of the motor is fixedly connected to the rear end of a universal coupling component A, the universal coupling component A is rotatably connected to the middle position inside the fixed frame, the front end of the universal coupling component A is slidably connected to the rear end of a universal coupling component B, the universal coupling component B is rotatably connected to the middle position inside the rotating frame, a clamp is fixedly connected to the front end of the universal coupling component B, and a drill bit is clamped and fixed at the middle position of the front end of the clamp.

[0008] According to an embodiment of the utility model, the front end middle position of the bottom of the fixing frame is rotatably connected to the rear end position of the rotating plate, and the front end position of the rotating plate is rotatably connected to the rear middle position of the bottom of the rotating frame.

[0009] According to an embodiment of the utility model, a half gear A is fixedly installed at the middle front position of the fixed frame, and the center position of the half gear A is coaxial with the rotation position of the rear end of the rotating plate.

[0010] According to an embodiment of the utility model, a half gear B is fixedly connected to the rear position of the rotating frame, the center position of the half gear B is coaxial with the rotation position of the front end of the rotating plate, and the half gear B meshes with the half gear A.

[0011] According to an embodiment of the utility model, a threaded hole is respectively opened at the front and rear ends of the bottom of the rotating plate, and a positioning bolt A is rotatably connected in the threaded hole at the front end of the rotating plate, and the top position of the positioning bolt A is in contact with the bottom position of the half gear B.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

When the fixed frame and the rotating frame are rotating, the joints of the universal coupling A and the universal coupling B themselves will be adaptively adjusted in position, and there will be no interference in the angle conversion process between the fixed frame and the rotating frame. After the motor is started, the drill bit can still be clamped by the matching transmission clamp of the motor universal coupling A and the universal coupling B.

[0015] The device replaces the traditional straight shaft through the multi-joint design of the universal coupling A and the universal coupling B, reduces the length of the shaft and the drill bit, and is more suitable for drilling in narrow locations.

[0016] When the top position of the positioning bolt A and the top position of the positioning bolt B are respectively in contact with the half gear B and the half gear A, the positions of the fixed frame and the rotating frame can be limited to rotate, thereby avoiding joint position deviation during the punching process.

[0025] The implementation of the utility model is further described in detail below in conjunction with the drawings and examples.

[0026] Embodiment 1:

[0027] As attached Figure 1 To Attachment Figure 4 As shown:

[0028] The utility model provides a drilling structure capable of changing an angle, comprising a fixed frame 1; a motor 103 is fixedly connected to the rear end of the fixed frame 1; a rotating shaft of the motor 103 is fixedly connected to the rear end of a universal coupling component A104; the universal coupling component A104 is rotatably connected to the middle position inside the fixed frame 1; a front end of the universal coupling component A104 is slidably connected to the rear end of a universal coupling component B202; the universal coupling component B202 is rotatably connected to the middle position inside a rotating frame 2; a clamp 203 is fixedly connected to the front end of the clamp 203; and a clamp 203 is fixedly connected to the middle position inside the clamp 203. A drill bit 204 is clamped and fixed in position; the middle position of the front end bottom of the fixed frame 1 is rotatably connected to the rear end position of the rotating plate 101; the front end position of the rotating plate 101 is rotatably connected to the middle rear position of the bottom of the rotating frame 2; a half gear A102 is fixedly installed at the middle front position of the fixed frame 1; the center position of the half gear A102 is coaxial with the rear end rotation position of the rotating plate 101; a half gear B201 is fixedly connected to the middle rear position of the rotating frame 2; the center position of the half gear B201 is coaxial with the front end rotation position of the rotating plate 101; and the half gear B201 meshes with the half gear A102.

[0029] Among them, a threaded hole is respectively opened at the front and rear ends of the bottom of the rotating plate 101, and a positioning bolt A105 is rotatably connected to the threaded hole at the front end of the rotating plate 101, and the top position of the positioning bolt A105 is fitted with the bottom position of the half gear B201, and a positioning bolt B106 is rotatably connected to the threaded hole at the rear end of the rotating plate 101, and the top position of the positioning bolt B106 is fitted with the bottom position of the half gear A102. When the top position of the positioning bolt A105 and the top position of the positioning bolt B106 are fitted with the half gear B201 and the half gear A102 respectively, the position of the fixed frame 1 and the rotating frame 2 can be limited to rotate, thereby avoiding the occurrence of joint position displacement during the punching process.

[0030] When using:

[0031] In normal use, the motor 103 is started, and the rotating shaft of the motor 103 drives the universal coupling A104 to rotate.

[0032] When the angle needs to be changed, the fixed frame 1 and the rear end of the rotating plate 101 are rotated through the meshing of the half gear B201 and the half gear A102, and the front end position of the rotating plate 101 and the bottom of the rotating frame 2 are rotated to change the current angle of the fixed frame 1 and the rotating frame 2. When the fixed frame 1 and the rotating frame 2 are rotated, the universal coupling A104 and the universal coupling B202 will adjust the position of the joints of the universal coupling A104 and the universal coupling B202 themselves adaptively, and there will be no interference in the angle conversion process between the fixed frame 1 and the rotating frame 2. After the motor 103 is started, the drill bit 204 can still be clamped and fixed by the matching transmission clamp 203 of the motor 103 universal coupling A104 and the universal coupling B202.
