Description

Technical Field

[0001] This utility model relates to the field of electric drills, and in particular to an anti-tilt handheld electric drill. Background Technology

[0002] Electric drills are commonly used tools in the machinery, construction, and decoration industries for drilling, driving in screws, and removing screws. They are also frequently used tools in the decoration industry.

[0003] Application number 202321783662.1 discloses an anti-tilt handheld electric drill, including a drill body. The upper surface of the drill body has an upper sliding groove, and the inner walls of both sides of the upper sliding groove have inner sliding grooves.

However, since this anti-tilt mechanism only limits movement from one side, vibrations during use may cause the anti-tilt mechanism to change angle, affecting its anti-tilt effect. Utility Model Content

[0004] This utility model discloses an anti-tilt handheld electric drill, which aims to solve the technical problem that the anti-tilt mechanism may change angle due to vibration during use, thus affecting the anti-tilt effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An anti-tilt handheld electric drill includes a drill body and a drill bit, and further includes: an inner frame, fixedly connected to one outer wall of the drill body, with the drill bit located inside the inner frame, and multiple sliding strips fixedly connected to multiple outer walls of the inner frame; an outer frame, movably sleeved outside the inner frame, with multiple inner walls of the outer frame respectively provided with sliding grooves, multiple sliding strips movably connected to the sliding grooves, and springs fixedly connected between the sliding strips and the sliding grooves; multiple square through-slots I, penetrating multiple inner walls of the outer frame; multiple square through-slots II, penetrating multiple inner walls of the inner frame; a dust collection mechanism installed at the bottom of the outer frame; and a shielding mechanism installed on both sides of the outer frame.

[0007] The inner wall of one side of the inner frame is provided with multiple screw holes, and the top outer wall of the electric drill body is fixedly connected with multiple protrusions, and each protrusion is inserted with a screw, and one end of the multiple screws is movably engaged in the multiple screw holes.

[0008] An L-shaped limiting plate is fixedly connected to the bottom outer wall of the electric drill body, and one end of the L-shaped limiting plate is movably attached to one side of the outer wall of the inner frame.

[0009] By setting an inner frame and an outer frame, the inner frame is fixed to the outer wall of the electric drill body, and the outer frame is movably sleeved on the outer periphery of the inner frame, thereby achieving synchronous limiting on all four sides. This ensures that the drill bit is always perpendicular to the wall when drilling, which is more stable and has a better anti-tilting effect compared to single-sided limiting.

[0010] In a preferred embodiment, the shielding mechanism includes: two side supports, symmetrically fixedly connected to the opposite outer walls of the outer frame; two winding rods, rotatably connected to each side support, and a shielding cloth is wound around each winding rod; and two spring-loaded components, simultaneously connected to one end of the winding rod and the side support.

[0012] With the shielding mechanism in place, the shielding cloth can be pulled down with a rope to block both sides during drilling, preventing dust generated during drilling from overflowing from both sides. The structure of the rebound component and the winding rod connecting the shielding cloth allows for quick switching between shielding and visibility modes, facilitating operation during work.

[0013] In a preferred embodiment, the dust collection mechanism includes: a bottom groove, which extends through the inner wall of the bottom end of the outer frame; and a square magnetic frame, which is snapped into and magnetically adsorbed onto the inner wall of the bottom groove.

[0015] With a dust collection mechanism and dust collector bag installed, dust can be collected without additional accessories, optimizing the versatility of the electric drill. It is also easy to disassemble and clean the dust remaining in the dust collector bag.

[0016] As described above, an anti-tilt handheld electric drill includes a drill body and a drill bit, and further includes: an inner frame, fixedly connected to one outer wall of the drill body, with the drill bit located inside the inner frame; multiple sliding strips fixedly connected to multiple outer walls of the inner frame; an outer frame, movably sleeved outside the inner frame; multiple inner walls of the outer frame respectively provided with sliding grooves; multiple sliding strips movably connected to the sliding grooves; and springs fixedly connected between the sliding strips and the sliding grooves; multiple square through-slots I, penetrating multiple inner walls of the outer frame; multiple square through-slots II, penetrating multiple inner walls of the inner frame; a dust collection mechanism installed at the bottom of the outer frame; and a shielding mechanism installed on both sides of the outer frame.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] The anti-tilt handheld electric drill disclosed in this utility model is mainly used in scenarios where electric drills are used for drilling holes.

The inner frame 2 is installed on multiple inner walls of the inner frame 2; the dust collection mechanism 4 is installed at the bottom of the outer frame 1; the shielding mechanism 5 is installed on both sides of the outer frame 1. The inner frame 2 is fixed to the outer wall of the drill body 3, and the outer frame 2 is movably sleeved on the outer periphery of the inner frame 2. Under the action of the spring 13, when the outer frame 2 is pressed against the wall, the position of the inner frame 2 in the outer frame 1 can also be adjusted according to the drilling depth, thereby achieving synchronous limiting on all four sides, thus ensuring that the drill bit 10 is always perpendicular to the wall when drilling for a long time. Compared with single-sided limiting, it has higher stability and better anti-tilting effect.

[0026] Reference Figure 2 In a preferred embodiment, a plurality of screw holes 6 are provided on one side inner wall of the inner frame 2, and a plurality of protrusions 8 are fixedly connected to the top outer wall of the electric drill body 3, and a screw 7 is inserted in each protrusion 8, with one end of the plurality of screws 7 movably engaged in the plurality of screw holes 6.

[0027] Reference Figure 2 In a preferred embodiment, an L-shaped limiting plate 9 is fixedly connected to the bottom outer wall of the electric drill body 3, and one end of the L-shaped limiting plate 9 is movably attached to one side outer wall of the inner frame 2. The L-shaped limiting plate 9 is used to abut against one side of the inner frame 2 to form a support and assist in the stable connection between the inner frame 2 and the protrusion 8.

[0028] Reference Figure 4 In a preferred embodiment, the dust collection mechanism 4 includes: a bottom groove 401, which is disposed through the bottom inner wall of the outer frame 1; and a square magnetic frame 402, which is snapped into and magnetically adsorbed onto the inner wall of the bottom groove 401.

[0029] Reference Figure 4In a preferred embodiment, the dust collection mechanism 4 further includes: a mounting frame 403, fixedly connected to the bottom outer wall of the square magnetic frame 402; and a dust collection bag 404, fixedly connected to the bottom outer wall of the mounting frame 403. The dust collection mechanism 4 connects the dust collection bag 404 by the square magnetic frame 402 snapping into and adsorbing it into the bottom groove 401. After the dust collection bag 404 is installed, the dust generated during the drilling process will fall directly into the dust collection bag 404 for temporary storage. Dust collection is achieved without the need for additional accessories, optimizing the multi-functionality of the electric drill. It is also easy to disassemble and convenient to clean the dust remaining in the dust collection bag 404 after disassembly.

[0030] Reference Figure 5 In a preferred embodiment, the shielding mechanism 5 includes: two side supports 501, symmetrically fixedly connected to the outer walls of opposite sides of the outer frame 1; two winding rods 507, rotatably connected to each side support 501, and each winding rod 507 is respectively wound with a shielding cloth 506; and two spring-loaded components 502, which are connected to one end of the winding rod 507 and the side support 501.

When drilling, the shielding cloth 506 can be pulled down by the hanging rope 504 to open the shielding cloth 506 and cover the square through-slot 12 on the outer frame 1, thereby sealing the two sides and preventing dust generated during drilling from overflowing from the two sides. With the structure of the rebound component 502 and the winding rod 507 winding around the shielding cloth 506, the shielding cloth 506 can be quickly rebounded by releasing the hanging rope 504, opening the position of the square through-slot 12, and quickly switching between shielding and visibility modes, which facilitates the operation during work.

[0032] Working principle: The inner frame 2 is fixed to the outer wall of the drill body 3, and the outer frame 2 is movably sleeved on the outer periphery of the inner frame 2. Under the action of the spring 13, when the outer frame 2 is pressed against the wall, the position of the inner frame 2 in the outer frame 1 can also be adjusted according to the drilling depth, thereby achieving synchronous limiting on all four sides, thus ensuring that the drill bit 10 is always perpendicular to the wall when drilling for a long time. Compared with single-sided limiting, it has higher stability and better anti-tilting effect.
