[0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

[0003] Flashlights are commonly used lighting tools for daily maintenance workers, which can assist maintenance workers in observing parts that cannot be covered by conventional lighting. However, due to the characteristic of hand-held flashlights, one hand needs to be allocated to hold the flashlight during the maintenance process, which will restrict the movement and operation of maintenance workers. Existing designs have flashlights that are fixed by brackets or magnets. During work, the flashlight can be fixed on a ferromagnetic object, which is convenient for placing the flashlight and freeing the maintenance worker's hands to complete the maintenance action.

[0004] In terms of the fixing of magnetic flashlights, the fixing position is arbitrary and adjustable, the cost is low, and in actual use, the performance is better than the flashlight fixed by the bracket, and it has an irreplaceable position. However, for some precision instruments, the magnetic field will affect their normal operation and even cause accidents, so anti-magnetic is required; at this time, the flashlight with magnetic fixing cannot be used in this scene, which limits the convenience of maintenance in this scene and reduces work efficiency.

[0022] By setting the positioning component, the square permanent magnetic material can maintain a constant relative position with the base when rotating to a required position, thereby achieving continuous maintenance of the magnetism of the magnetic valve or maintaining the magnetic valve to be non-magnetic.

[0023] Preferably, the base is in contact with the permanent magnetic material, and a side surface of the base and / or the permanent magnetic material in contact is configured as a rough surface to increase the friction force of sliding friction, thereby assisting in maintaining the position of the permanent magnetic material.

[0037] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0038] Embodiment 1 A magnetically controllable flashlight

[0039] like Figure 1 The magnetically controllable flashlight shown in the figure comprises a lighting end 100 and a holding end 200 opposite to the lighting end 100, wherein the holding end 200 is provided with a magnetic valve 400 capable of opening and closing the magnetic field. Figure 2 As shown, the magnetic valve 400 includes a base 410 and a rotation area 420, wherein the base 410 includes a first half block 411 and a second half block 412 that are independent of each other, and a magnetic resistance material 413 for connecting the first half block 411 and the second half block 412. The first half block 411 and the second half block 412 are made of soft magnetic material. The magnetic resistance material 413 includes two pieces that are opposite to each other, and the first half block 411 and the second half block 412 are connected to each other through two pieces of magnetic resistance materials 413 that are oppositely arranged. The rotation area 420 is arranged in the base 410. A square permanent magnetic material 421 is rotatably arranged in the rotating zone 420; the square permanent magnetic material 421 can rotate in the rotating zone 420 so that both ends of the square permanent magnetic material 421 can simultaneously contact with the two pieces of anti-magnetic material 413 connecting the first half block 411 and the second half block 412; and the square permanent magnetic material 421 can continue to rotate so that both ends of the square permanent magnetic material 421 can simultaneously contact with the two inner side surfaces of the first half block 411 and the second half block 412 facing the rotating zone 420.

[0040] The maintenance personnel control the holding position of the square permanent magnetic material 421 after rotation, control its contact relationship with the magnetic resistance material 413 and the soft magnetic material, and then control the magnetic opening and closing of the magnetic valve 400. When the square permanent magnetic material 421 in the rotating area 420 rotates to the two ends and contacts the magnetic resistance material 413 at the same time, the magnetic valve 400 of the flashlight does not have magnetism, and can be used near the precision instrument without affecting the function of the precision instrument; when leaving the precision instrument and needing to be fixed, the square permanent magnetic material 421 can be optionally rotated to the two ends and contact the soft magnetic material, and the axis of the square permanent magnetic material 421 is perpendicular to the line connecting the two pieces of magnetic resistance material 413. At this time, the magnetic valve 400 has magnetism, and the flashlight can be adsorbed and fixed to the required working position based on the magnetism of the magnetic valve 400, so as to achieve stable holding, thereby freeing the hands of the maintenance personnel, so that the maintenance personnel can perform maintenance more properly.

[0041] Preferably, the rotation of the square permanent magnetic material 421 can be electrically driven or manually driven.

Preferably, the protrusions and depressions are hemispherical to facilitate the application of force by maintenance personnel. Through the setting of the positioning component, the square permanent magnetic material 421 can achieve self-positioning and retention when it is rotated to the required position, thereby facilitating the continuous maintenance of the magnetism of the magnetic valve 400 or maintaining the magnetic valve 400 without magnetism. The setting method of the positioning component can be adjusted according to the actual use situation, and other positioning methods can be selected, such as groove locking, spring positioning pins, etc.
