Abstract
Description
Technical Field
[0001] This utility model relates to the field of drill pipe operation, and in particular to a universal electric drill gun. Background Technology
[0002] Existing electric drill guns include the common electric drill guns commonly found on the market. These electric drill guns cannot adjust the drill bit angle, which greatly limits their use when working in confined spaces. They have a narrow range of applicable scenarios, cannot complete complex angle operations, reduce work efficiency, and have poor ease of operation.
[0003] In confined spaces such as inside kitchen cabinets, furniture gaps, and wall corners, it is difficult for a fixed-angle drill bit to reach the work point. The straight handle design of ordinary electric drill guns can cause interference between the machine body and the wall, making it impossible to align the drill bit with the target position. Forcing operation may also cause the drill hole to deviate or slip due to unstable force, or even damage the workpiece or the electric drill gun itself.
[0004] For drilling at non-vertical or non-horizontal angles, drill guns with non-adjustable angles are almost impossible to meet. Forcibly fixing the drill gun angle by changing hand posture or using external force not only makes it difficult to ensure drilling accuracy but also significantly increases the difficulty of operation, easily causes hand fatigue, and may even lead to safety hazards such as the drill gun slipping from the hand. Utility Model Content
[0005] This utility model provides a universal electric drill gun, which solves the problems of ordinary electric drill guns, such as the inability to adjust the drill bit angle, the narrow range of applicable scenarios, the inability to complete complex angle operations, the difficulty of the drill bit at a fixed angle to reach the work point, and the possibility that forced operation may cause the drill hole to deviate or slip due to unstable force, or even damage the workpiece or the electric drill gun itself. This reduces work efficiency, makes operation inconvenient, easily causes hand fatigue, and may even cause safety hazards, such as the problem of the electric drill gun slipping out of the hand.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a universal electric drill gun, including a drill gun body and a rotating sleeve. The drill gun body is provided with a power shaft, and the power shaft is provided with a first steering body. A second steering body is provided on one side of the first steering body. The first steering body and the second steering body have the same structure. The second steering body is provided with an output shaft. The first steering body includes a semi-toothed ball, and the semi-toothed ball of the first steering body meshes with the semi-toothed ball of the second steering body.
[0007] In the preferred embodiment, the drill bit body is provided with a hollow outer tube, the power shaft abuts against the outer tube, and a first bearing is provided between the power shaft and the outer tube.
[0008] In a preferred embodiment, a second outer hollow tube is provided outside the output shaft, a second bearing is provided between the output shaft and the second outer hollow tube, and the second outer hollow tube is connected to the rotating sleeve.
[0009] In a preferred embodiment, the rotating sleeve includes an outer sleeve, an inner sleeve that is rotatably connected to the outer sleeve, a threaded hole on the outer sleeve, the outer sleeve being connected to an outer hollow tube, and the inner sleeve being connected to a second outer hollow tube.
[0010] In a preferred embodiment, the first steering body includes a U-shaped frame, a third through hole at the bottom of the U-shaped frame, a drive shaft passing through the third through hole and connected to a semi-tooth ball, arc-shaped toothed rings on both sides of the U-shaped frame, and rotating shafts at both ends of the U-shaped frame, with through holes on the rotating shafts.
[0011] In a preferred embodiment, the arc-shaped toothed ring on the second steering body meshes with the arc-shaped toothed ring on the first steering body.
[0012] In a preferred embodiment, two connecting rods are provided between the first steering body and the second steering body, and the connecting rods have second through holes at both ends, with the rotating shaft abutting against the second through holes.
[0013] In a preferred embodiment, the limiting rod includes a screw, one end of which is provided with a pressure ring and multiple pressure teeth, one end of the connecting rod is provided with multiple second pressure teeth, and the other end of the screw is provided with a tightening cap.
[0014] In the preferred embodiment, one end of the screw rests against the through hole, and the screw is connected to the threaded hole.
[0015] The beneficial effects of this utility model are as follows: When the rotating sleeve rotates, the semi-toothed ball of the second steering body and the semi-toothed ball of the first steering body rotate, causing the arc-shaped toothed ring of the second steering body and the arc-shaped toothed ring of the first steering body to rotate. This causes the output shaft to rotate relative to the power shaft. When it rotates to the angle required by the operator, the limiting rod rotates in the opposite direction, so that the multiple pressing teeth of the limiting rod tightly abut against the multiple second pressing teeth of the connecting rod, making the connecting rod and the first steering body fit tightly together, preventing the first and second steering bodies from rotating, thereby limiting the angle of the output shaft.
[0016] The drill gun body is driven to work, the power shaft of the electric drill gun rotates, causing the half-tooth ball connected to the power shaft to rotate, causing the half-tooth ball on the second steering body to rotate, causing the output shaft to rotate, so that the electric drill gun can perform operations.
[0017] The overall structure allows for output shaft angle adjustment, ensuring the drill bit is aligned with the target position. This prevents drilling deviation, slippage, or even damage to the workpiece or drill gun due to unstable force caused by unadjustable angles. The device is suitable for drilling at non-vertical or non-horizontal angles, offering a wide range of applications, high work efficiency, and convenient operation. By ensuring drilling accuracy and minimizing operational difficulty, the device avoids hand fatigue and safety hazards caused by unadjustable angles, making it highly valuable for widespread adoption.

Detailed Implementation
[0026] Example 1:
[0027] like Figure 1-6 The universal drill gun includes a drill body 1 and a rotating sleeve 4. The drill body 1 has a power shaft 2, and the power shaft 2 has a first steering body 5. A second steering body 6 is located on one side of the first steering body 5. The first steering body 5 and the second steering body 6 have the same structure. The second steering body 6 has an output shaft 3. The first steering body 5 includes a semi-toothed ball 502, which meshes with the semi-toothed ball of the second steering body 6. With this structure, when the angle of the output shaft 3 needs to be adjusted, the operator manually rotates the limiting rod 8 to move the pressure ring 802 at one end of the limiting rod 8 away from the first steering body 5. The operator then rotates the inner sleeve 402 with one hand to rotate the inner sleeve 402 relative to the outer sleeve 401.
[0028] When the rotating sleeve 4 rotates, the semi-toothed ball of the second steering body 6 and the semi-toothed ball 502 of the first steering body 5 rotate, causing the arc-shaped toothed ring of the second steering body 6 and the arc-shaped toothed ring 503 of the first steering body 5 to rotate. This causes the output shaft 3 to rotate relative to the power shaft 2. When it rotates to the angle required by the operator, the limiting rod 8 rotates in the opposite direction, so that the multiple pressing teeth 803 of the limiting rod 8 tightly abut against the multiple second pressing teeth of the connecting rod 7, so that the connecting rod 7 is tightly attached to the first steering body 5, preventing the first steering body 5 and the second steering body 6 from rotating, thereby limiting the angle of the output shaft 3.
[0029] The drill rig body 1 is driven to work, the power shaft 2 of the electric drill rig rotates, causing the semi-tooth ball 502 connected to the power shaft 2 to rotate, causing the semi-tooth ball on the second steering body 6 to rotate, causing the output shaft 3 to rotate, so that the electric drill rig can perform operations.
[0030] The overall structure allows for output shaft 3 angle adjustment. Adjusted output shaft 3 ensures the drill bit is aligned with the target position, preventing drilling deviation, slippage, or even damage to the workpiece or drill gun due to unstable force caused by unadjustable angles. The device is suitable for drilling at non-vertical or non-horizontal angles, offering a wide range of applications, high work efficiency, and convenient operation. The overall design ensures drilling accuracy, minimizes operational difficulty, and avoids hand fatigue and potential safety hazards caused by unadjustable angles.
[0031] In a preferred embodiment, the drill bit body 1 is provided with a hollow outer tube 102, the power shaft 2 abuts against the outer tube 102, and a first bearing 101 is provided between the power shaft 2 and the outer tube 102. With this structure,
[0032] In a preferred embodiment, a second outer hollow tube is provided outside the output shaft 3, and a second bearing is provided between the output shaft 3 and the second outer hollow tube. The second outer hollow tube is connected to the rotating sleeve 4. With this structure, the output shaft 3 is rotatably connected to the second outer hollow tube, the power shaft 2 is rotatably connected to the outer hollow tube 102, and the rotating motor of the electric drill is connected to the power shaft 2. The output shaft 3 is connected to the drill bit.
[0033] In a preferred embodiment, the rotating sleeve 4 includes an outer sleeve 401, on which an inner sleeve 402 is rotatably connected. The outer sleeve 401 has a threaded hole 403. The outer sleeve 401 is connected to the outer hollow tube 102, and the inner sleeve 402 is connected to the second outer hollow tube. With this structure, when the angle of the output shaft 3 needs to be adjusted, the operator manually rotates the limiting rod 8 to move the pressure ring 802 at one end of the limiting rod 8 away from the first steering body 5. The operator then rotates the inner sleeve 402 with one hand to make the inner sleeve 402 rotate relative to the outer sleeve 401. The outer sleeve 401 and inner sleeve 402 are rotatably connected, the outer sleeve 401 is connected to the outer hollow tube 102, and the inner sleeve 402 is connected to the second outer hollow tube, so that when the output shaft 3 rotates relative to the power shaft 2, the inner sleeve 402 rotates relative to the outer sleeve 401.
[0034] In a preferred embodiment, the first steering body 5 includes a U-shaped frame 501 with a third through hole at its bottom. The power shaft 2 passes through the third through hole and connects to a semi-toothed ball 502. Arc-shaped toothed rings 503 are provided on both sides of the U-shaped frame 501, and rotating shafts 504 are provided at both ends of the U-shaped frame 501. Through holes 505 are provided on the rotating shafts 504. With this structure, when the rotating sleeve 4 rotates, the semi-toothed ball of the second steering body 6 and the semi-toothed ball 502 of the first steering body 5 rotate, causing the arc-shaped toothed rings of the second steering body 6 and the arc-shaped toothed rings 503 of the first steering body 5 to rotate. This causes the output shaft 3 to rotate relative to the power shaft 2.
[0035] In a preferred embodiment, the arc-shaped toothed ring on the second steering body 6 meshes with the arc-shaped toothed ring 503 on the first steering body 5. This structure allows the arc-shaped toothed ring on the second steering body 6 to mesh with the arc-shaped toothed ring 503 on the first steering body 5, facilitating the rotation of the two hemi-balls. The outer sleeve 401 is connected to the U-shaped frame 501.
[0036] In a preferred embodiment, two connecting rods 7 are provided between the first steering body 5 and the second steering body 6. Each connecting rod 7 has a second through hole 701 at both ends, and the rotating shaft 504 abuts against the second through hole 701. With this structure, when the second steering body 6 rotates relative to the first steering body 5, the connecting rods 7 rotate with the second steering body 6 relative to the first steering body 5. Multiple second pressure teeth on the connecting rods 7 engage with pressure teeth 803 on the limiting rod 8.
[0037] In a preferred embodiment, the limiting rod 8 includes a screw 801, one end of which is provided with a pressure ring 802, and the pressure ring 802 is provided with multiple pressure teeth 803. One end of the connecting rod 7 is provided with multiple second pressure teeth, and the other end of the screw 801 is provided with a tightening cap 804. With this structure, when the angle required by the operator is reached, the limiting rod 8 is rotated in the opposite direction, so that the multiple pressure teeth 803 of the limiting rod 8 tightly abut against the multiple second pressure teeth of the connecting rod 7, so that the connecting rod 7 is tightly attached to the first steering body 5, preventing the first steering body 5 and the second steering body 6 from rotating, thereby limiting the angle of the output shaft 3.
[0038] In the preferred embodiment, one end of the screw 801 abuts against the through hole 505, and the screw 801 is connected to the threaded hole 403. With this structure, the limiting rod 8 is connected to the rotating sleeve 4, and one end of the limiting rod 8 passes through the through hole 505, allowing the pressure ring 802 to extend out of the through hole 505. After the angle is adjusted, the limiting rod 8 is rotated to move it upwards, so that the multiple second pressure teeth of the connecting rod 7 are pressed against the pressure teeth 803 on the limiting rod 8.
