[0009] A swinging component is installed inside the housing. One end of the swinging component is movably connected to the pressing component. When the gravity-sensing screwdriver is tilted, the other end of the swinging component swings to the upper end of the first cutting head or the upper end of the second cutting head under the action of gravity of the swinging component.

[0010] The press-and-extend structure, the press member, and the reset assembly work together to achieve the press-and-extend of the first cutter head and / or the second cutter head;

[0011] When the swinging member is located at the upper end of the first cutter head, the pressing member presses down, so that the pressing member, the swinging member and the first cutter head abut against each other in sequence, thereby realizing the pressing extension and retraction of the first cutter head.

[0012] In one embodiment, the oscillating element is a pendulum needle.

[0013] In one embodiment, one end of the oscillating member is connected to the pressing ball.

[0014] In one embodiment, the gravity-sensing screwdriver further includes a first guide member disposed within the housing. The first guide member is cylindrical, and the other end of the swing member passes through the first guide member and swings to the upper end of the first cutting head or the upper end of the second cutting head.

[0015] In one embodiment, the first guide member has a first notch and a second notch spaced apart from each other at the end away from the pressing member;

[0016] When the other end of the swing member swings to the upper end of the first cutter head, the swing member slides into the first notch. When the other end of the swing member swings to the upper end of the second cutter head, the swing member slides into the second notch.

[0017] In one embodiment, the gravity-sensing screwdriver further includes an auxiliary reset component, which is elastically connected to the pressing component and the first guide component.

[0018] In one embodiment, the auxiliary reset component is a conical spring sleeved outside the swing component, and the shape of the auxiliary reset component matches the swing trajectory of the swing component.

[0019] In one embodiment, the gravity-sensing screwdriver further includes a second guide member disposed within the housing, the second guide member having a first guide hole and a second guide hole;

[0020] The first cutting head penetrates the first guide hole, and the second cutting head penetrates the second guide hole.

[0021] In one embodiment, the first reset member is a spring sleeved on the first cutter head, and the first reset member elastically abuts against the second guide member and the tail end of the first cutter head respectively;

[0022] The second reset member is a spring sleeved on the second cutter head, and the second reset member elastically abuts against the second guide member and the tail end of the second cutter head respectively.

[0023] In one embodiment, the pressing member, the first guide member, and the outer shell are sequentially fitted together.

[0024] In one embodiment, the press-and-telescopic structure includes a rotating ring rotatably sleeved outside the press member and a press-and-telescopic portion disposed inside the first guide member, wherein the rotating ring is provided with a drive block that matches the press-and-telescopic portion.

[0025] In one embodiment, the cutter head assembly further includes a third cutter head, wherein the first cutter head, the second cutter head, and the third cutter head are spaced apart from each other;

[0026] The reset assembly further includes a third reset member that connects the third cutting head and the housing respectively;

[0027] When the gravity-sensing screwdriver is tilted, the other end of the swing member swings to the upper end of the first cutting head, the upper end of the second cutting head, or the upper end of the third cutting head under the action of gravity of the swing member.

[0028] When using this gravity-sensing screwdriver, to achieve the pressing and extending of the first cutting head, simply tilt the screwdriver so that the other end of the oscillating member swings to the upper end of the first cutting head under the action of gravity. The pressing member then presses down, causing the pressing member, the oscillating member, and the first cutting head to sequentially abut against each other, thereby achieving the pressing and extending of the first cutting head. When the gravity-sensing screwdriver needs to be used with different types or specifications of cutting heads (e.g., slotted, Phillips, Torx, or for example, 1.5mm, 2mm, 3mm, 4.5mm), the first and second cutting heads can be set to the required types.

[0029] Compared to traditional gravity-sensor screwdrivers, this gravity-sensor screwdriver allows for the pressing and extending of either the first or second cutting head. When changing different types or sizes of cutting heads, only tilting the gravity-sensor screwdriver combined with manual pressing is required. Compared to traditional screwdrivers, changing different types or sizes of cutting heads is more convenient, and unused cutting heads are stored inside the housing, eliminating the need for separate storage and preventing loss.
