[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0035] In the description of this invention, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this invention is usually placed, they are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0036] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0037] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0038] Please combine them together Figures 1 to 4 The present invention will now describe the lamp holder provided, which is used in miniature lamps. The lamp holder includes a fixing component 1, a supporting component 2, and a clamping component 3. The supporting component 2 includes a first supporting arm 21 and a second supporting arm 22 connected to the first supporting arm 21. The fixing component 1 is rotatably connected to the first supporting arm 21 and is used to fix the lamp. The fixing component 1 is located in the space 100 formed by the first supporting arm 21 and the second supporting arm 22. The clamping component 3 is rotatably connected to the second supporting arm 22 and is used for external installation.

[0039] It is understood that the support component 2 of the lamp holder includes a first support arm 21 and a second support arm 22 connected to the first support arm 21. The fixing component 1 is located in the space 100 formed by the first support arm 21 and the second support arm 22, so that the center points of the fixing component 1, the second support arm 22 and the clamping component 3 coincide. The fixing component 1 is rotatably connected to the first support arm 21 and is used to fix the lamp. Rotating the fixing component 1 causes the lamp to change its vertical illumination area. The clamping component 3 is rotatably connected to the second support arm 22 and is used for external installation. Rotating the second support arm 22 causes the first support arm 21, the fixing component 1 and the lamp to change their horizontal illumination area. Thus, after the lamp holder is fixed on the shoulder strap, the lamp holder can adjust the illumination direction of the lamp in multiple directions, improving its applicability.

[0040] Furthermore, since the fixing component 1 is located in the space 100 formed by the first support arm 21 and the second support arm 22, the center points of the fixing component 1, the second support arm 22 and the clamping component 3 coincide, so that after the miniature lamp is installed on the fixing component 1, the miniature lamp can be stably clamped on the epaulette by the clamping component 3.

[0041] It should be added that the first support arm 21 and the second support arm 22 are set at an angle. In implementation, the angle between the first support arm 21 and the second support arm 22 is 90 degrees, so that the center points of the fixing component 1, the second support arm 22 and the clamping component 3 coincide.

[0042] It should be noted that, depending on the placement of the lamp holder, it can be placed horizontally or vertically. For ease of understanding, in the relevant embodiments, the lamp holder is placed vertically.

[0043] In this embodiment, the support assembly 2 further includes a first fixing button 23 and a fixing member 24. The fixing assembly 1 includes a base 11 and a connecting portion 12 formed on the base 11. The first fixing button 23 passes through the first support arm 21 and is rotatably connected to the first support arm 21. The fixing member 24 passes through the connecting portion 12 and is connected to the first fixing button 23, so that the base 11 can be rotatably connected to the first support arm 21.

[0044] Specifically, the fixing member 24 can be a screw that passes through the connecting part 12 and is threadedly connected to the first fixing button 23, so that the fixing member 24 and the first fixing button 23 are locked together. Rotating the base 11 causes the base 11 to rotate within the vertical illumination area. The base 11 drives the connecting part 12 to rotate, the connecting part 12 drives the fixing member 24 to rotate, and the fixing member 24 drives the first fixing button 23 to rotate. The friction between the connecting part 12 and the first support arm 21 can produce a damping effect, and the friction between the first fixing button 23 and the first support arm 21 can also produce a damping effect. Therefore, the base 11 can drive the lamp to adjust the rotation angle of any position within the vertical illumination area.

[0045] Furthermore, the first fixing button 23 includes a first button body 231 and a first protrusion 232 connected to the first button body 231. The first support arm 21 is provided with a first groove 211 facing the first protrusion 232, and the first protrusion 232 can engage with the groove wall of the first groove 211.

[0046] Specifically, rotating the base 11 causes the connecting part 12 to rotate, which in turn causes the fixing part 24 to rotate. The fixing part 24 then causes the first button body 231 to rotate, which in turn causes the first protrusion 232 to rotate. When the first protrusion 232 rotates to the position of the first groove 211, the first protrusion 232 engages with the groove wall of the first groove 211, thereby fixing the base 11 and the lamp in the current position.

[0047] In implementation, two first protrusions 232 are provided and symmetrically arranged on both sides of the first knob body 231. This makes the first knob body 231 more stable, and consequently, the base body 11 and the lamp fixture more stable. Multiple first grooves 211 are provided and are spaced circumferentially on the first support arm 21. This allows the base body 11 and the lamp fixture to be fixed at multiple positions and angles within the vertical illumination area.

[0048] It should be noted that the first protrusion 232 is cylindrical with a height of approximately 1.5 mm. When the first protrusion 232 engages with the groove wall of the first groove 211, the friction between the first protrusion 232 and the first support arm 21 is minimized. In other words, when the first protrusion 232 is not yet inside the first groove 211, it abuts against the first support arm 21, causing elastic deformation and maximizing the friction between them. When the first protrusion 232 enters the first groove 211, its elastic deformation returns to its original position, and the friction between it and the first support arm 21 is minimized. Whether the first knob 231 rotates clockwise or counterclockwise, it is resisted by the engagement resistance between the groove wall of the first groove 211 and the first protrusion 232, thus positioning the first knob 231 in its current position, and consequently, positioning the base 11 and the lamp in their current positions.

[0049] When a rotational force is applied to the seat 11, the rotational force overcomes the resistance of the first protrusion 232 leaving the first groove 211. The first protrusion 232 is lifted by the groove wall of the first groove 211, and the first protrusion 232 deforms, causing the first protrusion 232 to leave the first groove 211.

[0050] When the first protrusion 232 leaves the first groove 211 but has not yet entered the next first groove 211, the first protrusion 232 remains deformed, and the friction between the first protrusion 232 and the first support arm 21 can still fix the base 11 and the lamp at an arbitrary angle.

[0051] The angle adjustment of the base 11 and the lamp can realize the illumination direction adjustment of the lamp with an elevation angle of 20° and a depression angle of 20° (not limited to this angle; if it is necessary to increase the angle, adjust the installation height of the base 11 to increase the range of rotation angle of the base 11).

[0052] In one embodiment, such as Figure 2 As shown, the fixing component 1 also includes a fastener 13, the base 11 includes a fixing ring 111 and a fixing part 112 connected to the fixing ring 111. The fixing ring 111 is used to fit the lamp. The fastener 13 is threadedly connected to the fixing part 112. When the fastener 13 is rotated, the fastener 13 can abut against the lamp so that the lamp is abutted against the fixing ring 111.

[0053] Specifically, the fastener 13 can be a bolt. When the fastener 13 is rotated, it moves relative to the fixed part 112, so that the fastener 13 can abut against the lamp, thereby abutting the lamp against the retaining ring 111.

[0054] It should be added that the base 11 can be made of plastic structural components. The base 11 has a certain degree of elasticity. After the fastener 13 abuts the lamp against the fixing ring 111, the deformation of the fixing ring 111 causes the clamping point between the fastener 13 and the lamp to maintain a constant pressure. This pressure causes the fastener 13 to self-lock, and at the same time, it causes the surface of the lamp and the top of the fastener 13 (clamping point) to maintain a long-term static friction force, thereby achieving a long-term fastening effect.

[0055] In this embodiment, the fastener 13 includes a handle 131 and a rotating part 132. The handle 131 is connected to the rotating part 132, and the rotating part 132 is threadedly connected to the fixing part 112. Rotating the handle 131 causes the rotating part 132 to rotate relative to the fixing part 112 and move simultaneously, allowing the rotating part 132 to abut against the lamp, thereby securing the lamp against the fixing ring 111. The handle 131 facilitates the rotation of the rotating part 132.

[0056] Furthermore, the handle 131 is provided with friction protrusions 133 in the circumferential direction. This increases the friction between the operator and the handle 131 when the operator rotates the handle 131.

[0057] Furthermore, the retaining ring 111 is also provided with an operating hole 113. By providing the operating hole 113, the operator can connect the retaining member 24 to the first retaining button 23.

[0058] In one embodiment, such as Figure 9 As shown, the base 11 includes a first clamping arm 114 and a second clamping arm 115. The first clamping arm 114 and the second clamping arm 115 are arranged opposite to each other and are respectively connected to the connecting part 12. The first clamping arm 114 and the second clamping arm 115 can elastically clamp the lamp.

[0059] Specifically, both the first clamping arm 114 and the second clamping arm 115 are elastic plastic structural components. The lamp can be elastically clamped between the first clamping arm 114 and the second clamping arm 115, thereby fixing the lamp.

[0060] In this embodiment, one end of both the first clamping arm 114 and the second clamping arm 115 is provided with a raised structure. The raised structure facilitates the clamping of the miniature lamp by the first clamping arm 114 and the second clamping arm 115.

[0061] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the support assembly 2 also includes a second fixing button 25. The second fixing button 25 includes a second button body 251, an abutment portion 252 and a locking portion 253 connected to the second button body 251. The clamping assembly 3 is provided with a locking groove 39. The second support arm 22 is provided with a first mounting hole 221 and a second mounting hole 222 communicating with the first mounting hole 221. The locking portion 253 can extend into the first mounting hole 221 and engage with the groove wall of the locking groove 39. The second support arm 22 can move relative to the clamping assembly 3 so that the second button body 251 enters the second mounting hole 222 from the first mounting hole 221, so as to lock the second support arm 22 between the abutment portion 252 and the clamping assembly 3.

[0062] Specifically, after the second button body 251 extends into the first mounting hole 221 and engages with the groove wall of the engaging groove 39, the second support arm 22 moves relative to the clamping assembly 3, allowing the second button body 251 to enter the second mounting hole 222 from the first mounting hole 221. This causes the second support arm 22 to engage between the abutment portion 252 and the clamping assembly 3. After engagement, the second support arm 22 makes frictional contact with the abutment portion 252 and the clamping assembly 3, allowing the second support arm 22 to rotate relative to the abutment portion 252 and the clamping assembly 3.

[0063] It should be added that there are two engaging portions 253, symmetrically arranged on both sides of the second button body 251. This makes the engagement of the engaging portions 253 with the groove wall of the engaging groove 39 more secure. In addition, there is a gap between the two engaging portions 252, which allows the two engaging portions 253 to converge towards the gap during the engagement process with the groove wall of the engaging groove 39, thus facilitating engagement with the groove wall of the engaging groove 39.

[0064] In this embodiment, an elastic protrusion 224 is provided at the connection between the walls of the first mounting hole 221 and the second mounting hole 222. By providing the elastic protrusion 224, during the process of the second button body 251 entering the second mounting hole 222 from the first mounting hole 221, the elastic protrusion 224 will undergo elastic deformation under the compression of the second button body 251. Therefore, without the action of external force, the second button body 251 will not detach from the second mounting hole 222.

[0065] Furthermore, the second support arm 22 is also provided with a through hole 225. By setting the through hole 225 and making the size of the through hole 225 according to actual needs, the elastic protrusion 224 changes its deformation strength due to the size of the through hole 225, thereby adjusting the ease and reliability of installing the second button body 251 into the second mounting hole 222. That is, it ensures that the second button body 251 can be smoothly installed into the second mounting hole 222 and that the second button body 251 is not easy to detach from the second mounting hole 222.

[0066] Furthermore, the second support arm 22 is also provided with a second protrusion 223, and the clamping assembly 3 is also provided with a second groove 31 facing the second protrusion 223. The second protrusion 223 can engage with the groove wall of the second groove 31. Rotating the second support arm 22 causes the second protrusion 223 to rotate, so that the second protrusion 223 can engage with the groove wall of the second groove 31, thereby fixing the second support arm 22 in the current position.

[0067] Furthermore, multiple second grooves 31 are provided and spaced circumferentially around the clamping assembly 3. By providing multiple second grooves 31, the second protrusion 223 can engage with the groove walls of the second grooves 31 at different positions, thereby adjusting the positioning angle of the second support arm 22 to adjust the positioning angle of the lamp. For example, if there are 12 second grooves 31 within a 360° circumference, the second support arm 22 rotates 30° with each rotation. If there are 24 second grooves 31 within a 360° circumference, the second support arm 22 rotates 15° with each rotation.

[0068] Of course, in other embodiments, multiple second protrusions 223 are provided and spaced apart circumferentially on the second support arm 22. Thus, by providing multiple second protrusions 223, the groove wall of the second groove 31 can engage with the second protrusions 223 at different positions, thereby adjusting the positioning angle of the second support arm 22 to adjust the positioning angle of the lamp. For example, if there are 12 second protrusions 223 within a 360° circumference, then rotating one second protrusion 223 will rotate the second support arm 22 by 30°. If there are 24 second protrusions 223 within a 360° circumference, then rotating one second protrusion 223 will rotate the second support arm 22 by 15°.

[0069] In one embodiment, such as Figures 6 to 8 As shown, the clamping assembly 3 includes a first clamping plate 32, a second clamping plate 33, a rotating shaft 34, and an elastic element 35. The first clamping plate 32 and the second clamping plate 33 are arranged opposite to each other and are rotatably connected to the rotating shaft 34. The elastic element 35 includes a body and two working parts connected to the body. The body is arranged around the rotating shaft 34, and the two working parts abut against the first clamping plate 32 and the second clamping plate 33 respectively.

[0070] Specifically, the elastic element 35 is a torsion spring. The operator presses the first clamping plate 32 and the second clamping plate 33 close to each other, so that the first clamping plate 32 and the second clamping plate 33 can simultaneously drive the two actuating parts to move in position, thereby causing the two actuating parts to drive the body to elastically deform. At this time, the first clamping plate 32 and the second clamping plate 33 are placed on an item such as an epaulette. When the first clamping plate 32 and the second clamping plate 33 are released, under the action of the elastic deformation force of the body, the two actuating parts simultaneously drive the first clamping plate 32 and the second clamping plate 33 to clamp onto the epaulette.

[0071] In this embodiment, the spring wire diameter of the elastic element 35 is 1.4mm and the included angle is 80°. The spring wire diameter and included angle can be adjusted to meet the needs of various clamping forces.

[0072] Furthermore, the rotating shaft 34 is also provided with two anti-detachment components 38, which are symmetrically arranged at both ends of the rotating shaft 34. In this way, the rotating shaft 34 will not detach from the first clamping plate 32 and the second clamping plate 33.

[0073] Furthermore, both the first clamping plate 32 and the second clamping plate 33 are provided with anti-slip textures 36. Specifically, the anti-slip textures 36 can be raised textures or concave textures, which increase the friction between the operator and the first clamping plate 32 and the second clamping plate 33, enhance the feel, and prevent slipping.

[0074] In one embodiment, such as Figure 1 As shown, both the first clamping plate 32 and the second clamping plate 33 are provided with interlocking teeth 37. This makes it easier for the first clamping plate 32 and the second clamping plate 33 to clamp soft objects such as clothing and woven fabrics, and enhances the anti-slip ability of the clamping assembly 3.

[0075] In this embodiment, the number, length, and depth of the biting teeth 37 can be determined according to the width of the clothing or straps that are frequently clamped. If the clamped item is wide and soft, the number of biting teeth 37 can be increased appropriately, and vice versa.

[0076] The present invention also provides a miniature lamp, which includes the lamp holder of any of the above embodiments.

[0077] It is understood that the miniature lamp in this embodiment uses the lamp bracket of the above embodiment, so that after the lamp bracket is fixed on the epaulette, the lamp bracket can adjust the illumination direction of the lamp in multiple directions, thus improving its applicability.

[0078] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0079] The above description discloses only preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
