DETAILED DESCRIPTION

[0021] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the present invention is further described below in conjunction with the accompanying drawings.

[0022] Batteries can easily harm children and pollute the environment. Developed countries such as Europe and the United States have required that batteries must be removed with other tools. Therefore, this application is an improvement on the problem that batteries in pickers are easily removed.

[0023] like Figure 1 and Figure 2As shown, the present application is an improvement based on the existing magnetic pickup. An improved pickup comprises a handle 1, a telescopic rod 2 and a pickup head 3 connected in sequence, the telescopic rod 2 can be adjusted according to the use situation, and the handle 1 is provided with a concave-convex groove that is conducive to gripping. The picking head 3 includes a base 31 and a cover 32 that are socketed together. A battery assembly 4 is arranged in the base 31, a magnet block 6 is arranged at the end of the cover 32 away from the base 31, and a lighting assembly 5 is arranged in the cover 32, and the lighting assembly 5 is elastically matched with the battery assembly 4; the battery assembly 4 includes a battery sleeve 41 that is upside down and arranged in the base 31 and a battery 42 that is arranged in the battery sleeve 41, and the battery 42 can be a dry cell battery, a button cell, etc.; the outer wall of the battery sleeve 41 is provided with an external thread that cooperates with the internal thread arranged on the inner wall of the base 31, and the outer wall of the base 31 is provided with an external thread that cooperates with the internal thread arranged on the inner wall of the cover 32; the top wall of the battery sleeve 41 is provided with a wire inlet hole 411 and a disassembly slot hole, and the battery 42 is used to selectively power the lighting assembly 5 through the wire inlet hole 411; the disassembly slot hole is used to cooperate with tools to disassemble and assemble the battery sleeve 41 and the base 31. In the present application, the rotation directions of the internal thread arranged on the inner wall of the base 31 and the external thread arranged on the outer wall are arranged in opposite directions to each other, so as to reduce the fracture scrap caused by the internal and external spiral grooves during the processing of the parts, that is, to increase the strength of the threaded part of the parts under the same wall thickness.

[0024] It can be understood that the picker of the present application can be telescopically adjusted according to the usage conditions through the telescopic rod 2, and the battery assembly 4 selectively supplies power to the lighting assembly 5 through elastic cooperation with the lighting assembly 5.

[0025] Specifically, the lighting assembly 5 of the present application includes a lamp holder 51 made of insulating material and an LED lamp 52 arranged on the lamp holder 51. The LED lamp 52 radiates outward through a light-transmitting hole 61 arranged on the magnet block 6, and the positive and negative pins of the LED lamp 52 pass through the lamp holder 51 and are selectively connected to the battery 42; the lamp holder 51 is elastically embedded between the cover 32 and the battery cover 41, and the cover 32 is rotated to connect the positive and negative pins of the LED lamp 52 to the battery 42 to achieve lighting; conversely, the cover 32 is rotated to separate the positive and negative pins of the LED lamp 52 from the battery 42, that is, the lighting is turned off.

[0026] like Figure 3As shown, the lamp holder 51 is a circular step structure, including a circular plate 511 and a spring seat 512 which are coaxially arranged in one piece, the outer diameter of the circular plate 511 being larger than the outer diameter of the spring seat 512; a mounting slot 513 is arranged in the middle of the upper end surface of the circular plate 511, which is used to assemble the LED lamp 52; and the upper end surface of the circular plate 511 abuts against the retaining ring 321 arranged in the sleeve cover 32. A cylindrical spring 9 is arranged on the spring seat 512, the inner diameter of the cylindrical spring 9 is transitionally matched with the outer diameter of the spring seat 512, the upper end surface of the cylindrical spring 9 abuts against the lower end surface of the circular plate 511, and the lower end surface abuts against the top wall of the battery sleeve 41, and the battery 42 in the battery sleeve 41 selectively supplies power to the LED lamp 52 through the elastic deformation of the cylindrical spring 9. A through hole 515 is provided in the middle of the lamp holder 51, through which the positive and negative pins of the LED lamp 52 are inserted; a wire groove 514 is also provided inside the lamp holder 51, and one pin of the LED lamp 52 is embedded in the lamp holder 51 to ensure that the cylindrical spring 9 is installed on the lamp holder 51 without tilting.

[0027] It can be understood that the upper end surface of the lamp holder 51 abuts against the retaining ring 321 provided in the sleeve cover 32, and the lower end is elastically connected to the battery sleeve 41 through the cylindrical spring 9 to restrict the lamp holder 51 in the sleeve cover 32. The inner diameter of the cylindrical spring 9 and the outer diameter of the spring seat 512 on the lamp holder 51 are selected to be transitionally matched, and the cylindrical spring 9 will not be separated from the lamp holder 51 when disassembled. The positive pin of the LED lamp 52 is connected to the positive electrode of the battery 42 through the wire entry hole 411 under the elastic deformation of the cylindrical spring 9, and the negative pin of the LED lamp 52 is connected to the negative electrode of the battery 42 through the wire entry hole 411 under the elastic deformation of the cylindrical spring 9, so that the power supply mechanism selectively supplies power to the LED lamp 52.

[0028] like Figure 4 As shown, in one embodiment, the wire entry hole 411 is arranged in the middle of the top wall of the battery sleeve 41, and the disassembly slot is a flat slot 8, which is used with a flat screwdriver; the flat slot 8 is arranged on the axis of the top wall of the battery sleeve 41, and the slot length is greater than the diameter of the wire entry hole.

[0029] like Figure 5 As shown, in another embodiment, the wire entry hole 411 is arranged in the middle of the top wall of the battery sleeve 41, and the disassembly slots are two disassembly holes 7, which are used in conjunction with the retaining ring pliers; the two disassembly holes 7 are symmetrically arranged around the wire entry hole on the same central axis relative to the axis of the battery sleeve 41.

[0030] In order to expand the scope of use and facilitate maintenance, an inspection mirror can also be magnetically connected to the magnet 6. When lighting is needed, the battery sleeve 41 is screwed into the inner cavity of the base 31, so that the cylindrical spring 9 is elastically deformed. Since the upper end of the lamp holder 51 is blocked by the retaining ring 321 and cannot move forward, the positive pin on the LED lamp 52 is connected to the positive pole of the battery 42, and the negative pin on the LED lamp 52 is connected to the negative pole of the battery 42, so the current is conducted and the LED lamp 52 is powered; when lighting is not needed, the battery sleeve 41 is rotated in the opposite direction, and the positive and negative pins of the LED lamp 52 are disconnected from the battery 42 under the action of the cylindrical spring 9, thereby turning off the lighting.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
