Some of the advance is made here, as the skilled person in the art can understand, the focus-amplifying assembly, the cutting assembly are already at present belonging to the effect assembly of the relatively common stage lamp. The focusing and amplifying assembly is used for adjusting the definition, the amplification and the reduction of the light spots or the images; the cutting component is used for cutting the light beam into various shapes so as to form light spots of different shapes. Therefore, the detailed description thereof is omitted, and the focus-enlarging assembly and the cutting assembly are directly summarized as a whole.

The first embodiment,

As shown in fig. 1-3, a hand-screw comprises a nut 1 capable of being directly screwed by hand and a screw 2 penetrating from the lower part of the nut 1, wherein the nut 1 comprises a main body 11 and a pressing part 12 positioned below the main body 11, and the pressing part 12 is a cylinder and positioned in the middle of the main body 11; the screw 2 penetrates out from the center of the pressing part 12; the pressing portion 12 is used for pressing the two accessories to be attached, and in the lighting fixture, is generally used for pressing the handle; meanwhile, the purpose that the pressing part 12 is a cylinder is to adopt a gasket for correction when the lamp and the handle have a fit tolerance, and the gasket is generally circular, so that the cylindrical pressing part 12 is more convenient.

The main body 11 is formed by six surfaces, and is divided into an upper surface 111, a lower surface 112, a front surface 113, a rear surface 114, a left side surface 115 and a right side surface 116, wherein the upper surface 111 is a runway-shaped plane, the lower surface 112 is equally divided into two intersected symmetrical inclined planes, the front surface 113 and the rear surface 114 are both planes and are symmetrical to each other, and the left side surface 115 and the right side surface 116 are both arc surfaces and are symmetrical to each other.

The front surface 113 and the rear surface 114 are designed to be flat surfaces, which are more convenient for hand twisting because the two surfaces are normally the surfaces directly contacted by fingers. The other surfaces are designed to highlight the aesthetic feeling of the appearance design.

Example II,

As shown in fig. 4, unlike the first embodiment, the concave groove 1121 is formed on the lower surface 112, and the design of the groove 1121 is significant in saving material, i.e., reducing cost, and does not affect the overall appearance of the lamp because the lower surface 112 is not visible when the thumbscrew is locked on the lamp. It is understood that, since the second embodiment is the same as the first embodiment except for the lower surface 112 shown in fig. 4, the description thereof is not repeated.

Example III,

As shown in fig. 5, a hand-screw comprises a nut 1 which can be directly hand-screwed and a screw 2 which penetrates from the lower part of the nut 1, wherein the nut 1 comprises a main body 11 and a pressing part 12 which is positioned below the main body 11, and the pressing part 12 is a cylinder and is positioned in the middle of the main body 11; the screw 2 penetrates out from the center of the pressing part 12; the pressing portion 12 is used for pressing the two accessories to be attached, and in the lighting fixture, is generally used for pressing the handle; meanwhile, the purpose that the pressing part 12 is a cylinder is to adopt a gasket for correction when the lamp and the handle have a fit tolerance, and the gasket is generally circular, so that the cylindrical pressing part 12 is more convenient.

The main body 11 is a rectangular parallelepiped, and the pressing portion 12 is located in a middle region below the main body 11.

Examples IV,

As shown in fig. 8, unlike the third embodiment, the concave groove 1121 is formed on the lower surface 112, and the design of the groove 1121 has the significance of relatively saving material, i.e., reducing cost, and the appearance is not affected because the groove is invisible after being locked. It can be understood that, since the fourth embodiment has the same surface as the third embodiment except the lower surface 112 as shown in fig. 8, the description thereof is not repeated.

Example V,

As shown in fig. 9 and 10, unlike the third embodiment, the pressing portion 12 and the screw 2 penetrating from the center of the pressing portion 12 are not located in the middle area below the main body 11, but are located on the sides.

Example six,

As shown in fig. 11, unlike the fifth embodiment, the concave groove 1121 is formed on the lower surface 112, and the design of the groove 1121 is significant in saving material, i.e., reducing cost, and the appearance is not affected because the groove is invisible after being locked. It is understood that, since the sixth embodiment is the same as the fifth embodiment except for the lower surface 112 shown in fig. 11, the description thereof is not repeated.

As an alternative to all the above embodiments, the joints between adjacent 2 surfaces of the six surfaces have rounded corners. The beneficial effect is that the hand is not easy to be cut.

As an alternative to all the above embodiments, the diameter of the compressing portion 12 is smaller than the width of the main body 11 in vertical projection. For the first to fourth embodiments, since the lower surface 112 is a racetrack-shaped plane, i.e., the diameter of the compacting section 12 is no greater than the width of the lower surface 112; for example five, because the lower surface 112 is cambered, i.e., the diameter of the compacting section 12 is no greater than the chord length of the lower surface 112. The beneficial effect of this embodiment is that the pressing part 12 is not protruded to the main body in the horizontal direction, and the appearance is more beautiful.

As an alternative to all the above embodiments, the nut 1 and the screw 2 are integrally formed.

As an optional implementation manner of all the above embodiments, the screw 2 is made of metal, and the nut 1 is made of plastic. Technically speaking, the upper part of the screw 2 is generally a nut, which is embedded in the nut 1 and is not visible from the outside. The beneficial effect lies in that the main body 1 is supported and firmer.
