Technical Field
[0001] This utility model belongs to the field of electric drill technology, and in particular relates to a lightweight handheld electric drill. Background Technology
[0002] Electric drills are commonly used tools in the machinery, construction, and decoration industries for drilling, driving screws, and removing screws. The working principle of an electric drill is that the rotor of a small-capacity electromagnetic rotary or reciprocating motor performs work by cutting through a magnetic field. This work is driven by a transmission mechanism, which in turn drives gears to increase the power of the drill bit, allowing it to scrape the surface of an object and penetrate it more effectively.
[0003] Patent CN202020821192.3 discloses a handheld lithium-ion electric drill, including a housing, a transmission wheel system, and a drill bit clamping device. A motor is fixedly connected inside the housing, and the output end of the motor is connected to the drill bit clamping device through the transmission wheel system. A handle is welded to the bottom of the housing, and a base is welded to the bottom of the handle. A cavity is provided inside the base, and a lithium-ion battery is fixedly connected inside the cavity. The motor is electrically connected to the lithium-ion battery. A solar panel is embedded in the top of the housing, and the solar panel is electrically connected to the lithium-ion battery.
[0004] In the aforementioned patent, the operator can only use one hand to hold the handle when using the electric drill. For some people with less strength, it is not possible to operate the electric drill well with one hand. Utility Model Content

[0034] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.
[0035] like Figure 1-5 As shown, a lightweight handheld electric drill includes a drill body 1, a handle 2, a battery compartment 3, and auxiliary mechanisms. The drill body 1 is a conventional cordless electric drill, which consists of a housing 11, a motor 12, a reduction gear set 13, and a drill bit connector 14. The handle 2 is fixed to the outer shell of the drill body 1. The battery compartment 3 is fixed to the bottom of the handle 2 and is used to hold the battery.
[0036] Specifically, the auxiliary mechanism includes a connecting seat 41, a rotating shaft 42, a connecting plate 43, a handle 44, a sleeve 45, an elastic element 46, a push rod 47, and a ball bearing 48. The connecting seat 41 is detachably connected to the side wall of the handle 2; the rotating shaft 42 is rotatably connected to the connecting seat 41, and the connecting shaft has a fixing hole 421; the connecting plate 43 is fixed to the rotating shaft 42; one end of the handle 44 is fixed to the connecting plate 43; the elastic element 46 is a spring, one end of which is fixed in the fixing hole 421; the push rod 47 is fixed to the end of the elastic element 46, and it can slide relative to the inner wall of the fixing hole 421; the sleeve 45 is fixed to the connecting seat 41, and one end of the rotating shaft 42 extends into the sleeve. Inside the sleeve 45, the rotating shaft 42 can rotate relative to the inner wall of the sleeve 45; the ball 48 is rotatably connected to the end of the push rod 47, and the inner wall of the sleeve 45 is provided with a slot for the ball 48 to be inserted. There are two slots. When the handle 44 is rotated to the vertical position, the ball 48 is aligned with one of the slots. When the handle 44 is rotated to the horizontal position, the ball 48 is aligned with the other slot. The auxiliary mechanism is detachably connected to the handle 2 through the connecting seat 41. The rotating shaft 42 drives the connecting plate 43 and the handle 44 to rotate. The elastic element 46 cooperates with the slots on the inner wall of the sleeve 45 through the push rod 47 and the ball 48 to realize the positioning and locking of the handle 44 in the vertical and horizontal positions. The shaft 42 can rotate within the sleeve 45, and the ball bearings 48 are embedded in different slots under elastic pressure to ensure that the handle 44 is stable at the required angle. Through the elastic locking mechanism, the user can flexibly adjust the angle of the handle 44 according to the work requirements, enhancing the control of both hands. It is especially suitable for operators with less strength, effectively reducing the risk of electric drill deviation and improving drilling accuracy and operating comfort.
[0037] As a preferred embodiment, a rubber sleeve 5 is fixedly fitted onto the handle 44. The rubber sleeve 5 provides additional cushioning to reduce fatigue during prolonged gripping, while also increasing frictional resistance to prevent hand slippage, further enhancing grip stability and safety. The rubber sleeve 5 has multiple anti-slip grooves 51, which enhance the frictional effect of the gripping contact surface through physical structure, maintaining a stable grip even when hands are wet or oily, reducing the risk of slipping. The anti-slip grooves 51 have multiple drainage holes 52, and the handle 44 has a water collection cavity 441. The handle 44 has a through hole 442, which is connected to the water collection chamber 441 and is corresponding to the mounting hole. A drain hole 52 is provided in the anti-slip groove 51. The through hole 442 connects the water collection chamber 441 to the external environment. During operation, liquid (such as sweat or water stains) flows into the water collection chamber 441 through the drain hole 52 for temporary storage, effectively guiding and collecting the liquid, and preventing the liquid from accumulating in the grip area and causing slippage. A water-absorbing component 6 is detachably provided in the water collection chamber 441. The water-absorbing component 6 quickly absorbs water and keeps the handle 44 dry, further optimizing the anti-slip performance.
[0038] In other embodiments, the water-absorbing component 6 includes a first screw 61, a fixing rod 62, a water-absorbing sponge 63, a pressure plate 64, and a limiting plate 65. The first screw 61 is screwed onto the end of the water-collecting cavity 441, and the water-collecting cavity 441 is provided with a thread that mates with the first screw 61. One end of the fixing rod 62 is fixed onto the end of the first screw 61. The water-absorbing sponge 63 passes through the fixing rod 62. The pressure plate 64 is provided on the fixing rod 62 and can slide relative to the fixing rod 62. The limiting plate 65 is screwed onto the end of the fixing rod 62, and the water-absorbing sponge 63 can fit against the inner wall of the water-collecting cavity 441.
[0039] In other embodiments, a protective baffle 7 is fixedly provided at the end of the handle 44.
[0040] In other embodiments, a second screw 8 is fixedly provided on the connecting seat 41, and the handle 2 is provided with a threaded hole 21 that mates with the second screw 8, so as to facilitate the disassembly of the handle 44.
[0041] In other embodiments, the rubber sleeve 5 is provided with a plurality of flow guide grooves 53. The flow guide grooves 53 are distributed on the surface of the rubber sleeve 5 in the form of inclined or wavy grooves, and cooperate with the drain hole 52 to form a directional flow path. The flow guide grooves 53 accelerate the liquid discharge speed, avoid local water accumulation, and further improve the anti-slip performance, making it suitable for wet or high-intensity working environments.
[0042] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
