摘要: A scale indicator has a key selecting device and multiple illuminating devices. The key selecting device is arranged on the keybed of the keyboard. The player can use the key selecting device to choose the musical key for the music that he or she wants to play. Each illuminating device is electrically connected to the key selecting device and corresponds to one of the keys of the keyboard instrument. The illuminating devices will show a note for the corresponding key after the player sets the key selecting device to a desired musical key. This can show the player the notes to which the keys of the keyboard respectively corresponded. To learn the keyboard instrument becomes easier.

摘要: A thermally insulating fixture includes a self-tapping screw, a fixed member mounted on the self-tapping screw, and a thermally insulating member wrapping the fixed member. The fixed member is provided with a first through hole. The thermally insulating member is provided with a second through hole and a positioning groove. The self-tapping screw extends through the second through hole of the thermally insulating member and the first through hole of the fixed member. A thermally insulating cover is mounted in the positioning groove and covers the self-tapping screw. The thermally insulating cover has a receiving space which receives the self-tapping screw. The thermally insulating cover has a positioning flange which is positioned in the positioning groove when the thermally insulating cover covers the head of the self-tapping screw.

摘要: A screw structure includes a screw and a washer mounted on the screw. The bottom face of the screw head is provided with a plurality of pressing portions. Each of the pressing portions has a top provided with a first plane and a bottom provided with a second plane having an area smaller than that of the first plane. Each of the pressing portions is provided with a first inclined face and a first steep arcuate face. The first inclined face is directed toward a clockwise direction of the screw when the screw is screwed. The first steep arcuate face is directed toward the external thread. When the screw is screwed into an article, the pressing portions press the washer, and an outer diameter of the washer is expanded outward and forms an expansion.

摘要: A thrust screw assembly includes a thrust screw and two threading dies for working the thrust screw. The thrust screw includes a first shank, a second shank, an external thread, and a thrust member. Each of the threading dies is provided with an external thread forming section and a flat portion forming section. In a first molding process, the first shank is worked to form the thrust member with two wing-shaped stop pieces. In a second molding process, the second shank is processed by the external thread forming section of each of the two threading dies to form the external thread on the second shank, and the two wing-shaped stop pieces is processed by the flat portion forming section of each of the two threading dies to form two flat portions on the two wing-shaped stop pieces simultaneously.

摘要: A thermally insulating fixture includes a support bracket, and a thermally insulating member mounted on the support bracket. The support bracket has a middle provided with a sheet plate. The sheet plate includes two hollow portions formed on two ends thereof. Each of the two hollow portions is provided with an abutment laminating the sheet plate. The sheet plate is provided with a through hole. The thermally insulating member covers an exterior of the support bracket. In practice, when the self-tapping screw extends through the through hole of the sheet plate and is screwed and tightened, a force is applied on the abutment. Thus, the abutment reinforces the strength of the support bracket to reduce deformation of the support bracket.
