Description

Technical Field

[0001] This utility model belongs to the field of electric drill technology, and in particular relates to a cordless 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 CN202222594543.3 discloses a handheld lithium-ion electric drill with a hand protection structure, including a handheld drill body and a rechargeable handle. The rechargeable handle is fixedly mounted on the lower end of the handheld drill body. A drill switch is provided at the connection between the handheld drill body and the rechargeable handle. A drilling light is provided above the drill switch on the handheld drill body. A soft hand pad is provided on the inner side of the rechargeable handle. A hand protection structure is provided on the outer side of the soft hand pad on the rechargeable handle. Heat dissipation grooves are provided on both sides of the rear end of the handheld drill body. A drilling head is provided at the front end of the handheld drill body. A carrying handle is provided at the upper end of the handheld drill body. Drill bit carrying plates are provided on the outer sides of both ends of the handheld drill body.

[0004] In the aforementioned patent, the hand protection mechanism is directly fixed to the machine body, making it difficult to disassemble. Furthermore, when using the electric drill, the operator can only operate by holding the handle with one hand. For individuals with less strength, it is not feasible to operate the electric drill effectively with one hand. Utility Model Content

[0040] like Figure 1-7 As shown, a cordless drill includes a drill body 1, a handle 2, a battery compartment 3, a handle 44, a handle 2 protective mechanism, and a handle 44 protective mechanism. The drill body 1 is a conventional cordless drill, which consists of a housing 11, a motor 12, a reduction gear set 13, and a drill bit connecting seat 14, etc. The handle 22 is fixed to the housing of the drill body 1. The battery compartment 33 is fixed to the bottom of the handle 22 and is used to hold the battery.

[0041] Specifically, the grip protection mechanism includes a fixing screw 61, a mounting plate 62, a first protective plate 63, a first elastic element 64, and a locking nut 65. The fixing screw 61 is symmetrically arranged on the grip 2, with one end fixed to the grip 2. The mounting plate 62 has a through hole for the fixing screw to pass through, allowing it to slide relative to the fixing screw. The first protective plate 63 is curved in an arc shape, made of rubber, and fixed to the mounting plate 62. The first elastic element 64 is a spring, with one end fixed to the grip 2 and the other end abutting against the mounting plate 62, providing a cushioning effect. The locking nut 65 is screwed onto the fixing screw 61, allowing adjustment of the distance between the first protective plate and the grip, and also facilitating the removal of the first protective plate.

[0042] Specifically, the handle protection mechanism includes a first connecting plate 71, a second connecting plate 72, a second elastic element 73, a second protective plate 74, a fixing plate 75, and an elastic protrusion 76. The fixing plate 75 is symmetrically fixed on the handle 44 and has an installation groove. The second connecting plate 72 has an insertion groove, and the first connecting plate 71 can slide relative to the inner wall of the insertion groove. The second elastic element 73 is a spring, with one end fixed in the insertion groove and the other end fixed on the first connecting plate 71. The second protective plate 74 is curved in an arc shape, made of rubber, and fixed on the second connecting plate 72. The elastic protrusion 76 is fixed on the side wall of the first connecting plate 71, and the inner wall of the installation groove has a fixing groove that mates with the elastic protrusion 76.

[0043] As a preferred embodiment, the handle is detachably connected to the grip via a connecting mechanism. The connecting mechanism includes a connecting seat 41, a rotating shaft 42, a third connecting plate 43, a connecting screw 49, a sleeve 45, a third 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 grip 2. The rotating shaft 42 is rotatably connected to the connecting seat 41 and has a fixing hole 421. The third connecting plate 43 is fixed to the rotating shaft 42. One end of the handle 44 is fixed to the third connecting plate 43. The third elastic element 46 is a spring, with one end fixed inside the fixing hole 421. The push rod 47 is fixed to the end of the elastic element 46 and 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 45. The rotating shaft 42 can rotate relative to the inner wall of the sleeve 45; the connecting screw 49 is fixed on the connecting seat, and the handle 2 is provided with a threaded hole 21 that mates with the connecting screw 49; 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 third elastic element 46 mates with the slots on the inner wall of the sleeve 45 through the push rod 47 and the ball 48 to achieve 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.

[0044] In other embodiments, a rubber sleeve 5 and a baffle 51 are fixedly fitted onto the handle.

[0045] In other embodiments, hooks 8 are provided on the side wall of the battery compartment.
