The light 200 and the adjustment component 500 are both disposed in the inner cavity of the storage component 300, and the collar 400 is disposed between the drill body 100 and the storage component 300. The storage component 300 includes components fixedly connected to the collar 400. The storage box 310 has an open top and a lid 320 is fastened to the top of the storage box 310. The light 200 is fixedly connected to the bottom of the lid 320. The adjustment component 500 includes a screw 510 that is rotatably connected to the lower part of the inner cavity of the storage box 310 via a bearing. The end of the screw 510 away from the bearing extends to the outside of the storage box 310 and is fixedly connected to a knob 511 for easy rotation. A threaded sleeve 520 is threaded onto the surface of the screw 510. A linkage is provided between the threaded sleeve 520 and the light 200.

[0028] The electric drill body 100 includes a body 110 and a drill bit 120. A connecting member is provided between the body 110 and the drill bit 120. A collar 400 is movably sleeved on the surface of the body 110. The body 110 can drive the drill bit 120 to operate through the connecting member, so that the drill bit 120 rotates to realize the drilling operation. At the same time, the collar 400 is movably connected to the body 110 so that the collar 400 can be rotated according to actual use needs to adjust the position of the storage component 300 on the body 110, thereby improving the illumination range of the lighting lamp 200.

[0029] The connector includes a first connector 130 and a second connector 140. The first connector 130 is fixedly connected to one end of the drill bit 120, and the second connector 140 is fixedly connected to the output shaft of the machine body 110. The first connector 130 and the second connector 140 are threadedly connected, and an anti-detachment component 150 that cooperates with the first connector 130 is slidably sleeved on the second connector 140.

[0030] It should be noted that the above-mentioned connector is a structure consisting of a mounting plate, fixing plate, adjusting ring and positioning rod in a hand drill that facilitates drill bit replacement, as disclosed in the existing announcement number CN221935442U. It can quickly and effectively connect and fix the drill bit 120, and can also prevent the connector from loosening. At the same time, the working principle of the above-mentioned body 110 is the same as that of the main body of the electric drill in the prior art. They are all prior art, so they will not be described in detail in this technical solution.

[0031] The linkage includes connecting rods 530 that are rotatably connected to both sides of the surface of the screw sleeve 520 via a rotating shaft. A support plate 540 is movably provided in the inner cavity of the storage box 310. The end of the connecting rod 530 away from the screw sleeve 520 is rotatably connected to the support plate 540 via a rotating shaft. The support plate 540 is located below the lighting lamp 200 and has a rotating component between it and the lighting lamp 200. When the screw 510 is rotated, it can drive the screw sleeve 520 to move along its axial direction, so that the screw sleeve 520 can use the linkage to drive the lighting lamp 200 to gradually move out or into the storage box 310, so as to realize the operation of exposing or hiding the lighting lamp 200.

[0032] The rotating component includes a support 550 located on the top of the support plate 540. A protruding plate 560 is movably connected to the surface of the support 550. The top of the protruding plate 560 is fixedly connected to the bottom of the lighting lamp 200. A sliding component is provided between the support 550 and the support plate 540. When the lighting lamp 200 is moved out of the storage box 310, the lighting lamp 200 is rotated, causing the protruding plate 560 to rotate on the surface of the support 550. This allows the lighting angle of the lighting lamp 200 to be adjusted, further improving the lighting range of the lighting lamp 200.

[0033] The collar 400 and the body 110, and the convex plate 560 and the support 550 are respectively connected by damping shafts. The central axes of the two damping shafts are set perpendicular to each other. The damping shafts can maintain the torsion angle fixation function to ensure that the collar 400 and the convex plate 560 do not loosen after rotation.

[0034] The sliding component includes a T-shaped groove 541 formed on the top of the support plate 540. A T-shaped block 551 is fixedly connected to the bottom of the support 550. The T-shaped block 551 is slidably connected to the inner cavity of the T-shaped groove 541. A damping pad 552 is fixedly connected to the bottom of the T-shaped block 551. The bottom of the damping pad 552 contacts the bottom of the inner wall of the T-shaped groove 541. When the lighting lamp 200 is moved out of the storage box 310, the lighting lamp 200 is moved so that the lighting lamp 200 uses the rotating component to drive the T-shaped block 551 and the damping pad 552 to slide in the inner cavity of the T-shaped groove 541. This allows the distance between the lighting lamp 200 and the drill bit 120 to be adjusted, which further improves the lighting range of the lighting lamp 200 and ensures that the drilling position is fully illuminated. The damping pad 552 can increase the friction between the T-shaped block 551 and the inner wall of the T-shaped groove 541, which has the effect of preventing loosening.

[0035] The inner wall of the storage box 310 is vertically fixed with a protrusion 311, and the surface of the support plate 540 is provided with a groove 542. The inner wall of the groove 542 is slidably connected to the surface of the protrusion 311. When the support plate 540 moves up and down in the inner cavity of the storage box 310, it can drive the groove 542 to move synchronously, so that the support plate 540 can slide on the surface of the protrusion 311 to achieve the guiding effect of the support plate 540, thereby improving the stability of the support plate 540 when moving up and down.

[0036] The working principle of this utility model is as follows: Rotating the collar 400 causes the storage component 300, adjustment component 500, and lighting lamp 200 to rotate synchronously on the surface of the machine body 110, allowing the lighting lamp 200 to be adjusted in angle around the drill bit 120. Rotating the knob 511 causes the screw 510 to rotate, which in turn causes the screw sleeve 520 to move. The screw sleeve 520 then moves one end of the connecting rod 530, and the other end of the connecting rod 530 pushes the support plate. 540 moves upward within the inner cavity of storage box 310. Support plate 540 drives groove 542, sliding member, rotating member, light 200, and lid 320 to move upward simultaneously. Support plate 540 slides on the surface of protrusion 311 until light 200 is completely removed from storage box 310. Then, depending on actual needs, decide whether to continue rotating knob 511 to adjust the lighting height of light 200. Pushing storage box 310 causes it to move light 200. 0. The rotating component, T-block 551, and damping pad 552 move on the surface of the support plate 540, and the T-block 551 slides in the inner cavity of the T-slot 541 to adjust the distance between the lighting lamp 200 and the drill bit 120; 0. The storage box 310 is moved, causing the lighting lamp 200 and the convex plate 560 to rotate synchronously, thereby adjusting the lighting angle of the lighting lamp 200. This allows for multi-angle adjustment of the lighting position of the lighting lamp 200 to ensure the lighting lamp 200... The lighting effect allows workers to perform drilling operations in dim environments. When the light 200 is not in use, it is slid back to its initial position and the knob 511 is turned in the opposite direction, so that the light 200 is finally placed inside the storage box 310. The lid 320 is then fastened onto the storage box 310, thus completing the concealment and storage of the light 200. This prevents the light 200 from being broken or damaged by external forces and helps extend its service life.

[0037] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
