[0013] Reference Figures 1 to 5 The embodiments of the present invention will be further described below.

[0014] This invention discloses a handheld drilling device for aluminum profiles, comprising two support bases 1 spaced apart. The surfaces of the two support bases 1 are provided with mounting grooves 10 along the length of each support base 1. An upper driving screw 11 and a lower driving screw 12, spaced vertically apart, are disposed within the mounting grooves 10. A fixing ring 120 is disposed at the middle of the lower driving screw 12. The thread directions of the lower driving screw 12 are opposite to those at both ends of the fixing ring 120. Two clamping blocks 2 are symmetrically disposed at the bottom of each support base 1, located on either side of the fixing ring 120. A clamping channel 3 for clamping and fixing the aluminum profile is formed between the two clamping blocks 2 and the support base 1. The two clamping blocks 2 are slidably engaged with the mounting grooves 10. First threaded holes 20 are provided on each clamping block 2, threadedly engaging with the lower driving screw 12. One end of each support base 1 is provided with a hole for driving the upper driving screw. A first drive motor that rotates the moving screw 11 and the lower drive screw 12 has a hand grip 4 fixedly connected to its other end. A drive column 5 is provided above each of the two support seats 1, slidingly engaging with the mounting slot 10. The bottom of each drive column 5 has a second threaded hole 50 that is threadedly engaged with the upper drive screw 11. An electric drill 6 is provided between the two drive columns 5, sliding vertically. An upper bracket 51 and a lower bracket 52 are fixedly connected to the side of each drive column 5 away from the hand grip 4. A drive screw 55 is provided between the upper bracket 51 and the lower bracket 52, rotating. A second drive motor 7 that drives the drive screw 55 is fixedly installed on the upper bracket 51. A fixing column 60 extending between the upper bracket 51 and the lower bracket 52 is provided on the side wall of the electric drill 6. The fixing column 60 is located near the upper end of the electric drill 6, and is threadedly connected to the drive screw 55.

[0015] Furthermore, a first slider 21 is provided on each side of the two clamping blocks 2, and a second slider 53 is provided on each side of the drive rod. Sliding grooves 13 are provided on the inner wall of the mounting groove 10 to allow the first sliders 21 and the second sliders 53 to slide left and right. This arrangement ensures greater stability and reduces the likelihood of wobbling during the sliding adjustment of the clamping blocks 2 and the drive rod along the mounting groove 10.

[0016] Furthermore, the electric drill 6 is provided with T-shaped connecting rods 61 on both sides, and T-shaped grooves 54 are provided on the two drive columns 5 to slide vertically with the connecting rods 61. The sliding engagement between the connecting rods 61 and the T-shaped grooves 54 makes the electric drill 6 more stable when drilling vertically, and it is less likely to vibrate and cause the hole to be drilled crookedly.

[0017] Furthermore, a motor housing 8 is fixedly connected to the ends of the two support bases 1 on the outside of the first drive motor. The motor housing 8 can protect the first drive motor.

[0018] Furthermore, a power supply 9 is located between the two motor housings 8 at the ends of the two support bases 1 furthest from the handgrip 4. The power supply 9 supplies power to the first drive motor, the second drive motor 7, and the electric drill 6. By placing the power supply 9 between the two motor housings 8, the position of the power supply 9 allows the two support bases 1 and the handgrip 4 to be connected to each other in a U-shape. This improves the overall rigidity of the handheld drilling device, making drilling more stable.

[0019] Furthermore, anti-slip protrusions 22 are arranged on the side of the two clamping blocks 2 that are close to each other. By providing anti-slip protrusions 22 on the clamping blocks 2, the clamping force of the clamping blocks 2 can be improved, and the structure is more stable.

[0020] Working Principle: In use, the handheld drilling device of this invention allows the user to hold the handle 4 and place the two support seats 1 on the aluminum profile to be drilled. The support seats 1 are then manually slid left and right along the aluminum profile to position the drilling along the X-axis. Once the vertical position is confirmed, the first drive motor is activated, rotating the lower drive screw 12. This causes the lower drive screw 12 to move the two clamping blocks 2 closer together, thus clamping and fixing the aluminum profile. Next, the first drive motor is activated, rotating the upper drive screw 11. This causes the upper drive screw 11 to move the two drive columns 5 synchronously back and forth, thus positioning the drilling along the Y-axis. After positioning, the second drive motor 7 is activated, rotating the drive screw 55. This causes the drive screw 55 to move the fixed column 60 up and down, which in turn drives the electric drill 6 to perform the drilling operation, achieving precise drilling of the aluminum profile.

[0021] The drilling device of the present invention uses a support base 1 and a clamping block 2 to fix it on an aluminum profile, and uses a drive column 5 to limit the electric drill 6, so as to achieve precise drilling of the aluminum profile and reduce the drilling deviation caused by the aluminum profile not being firmly fixed.

[0022] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
