The invention discloses a musical score bracket, which includes a bracket, a support panel, and a pressing part. Horizontal slide grooves are symmetrically arranged on both sides of the middle part of the support panel, and a pressing plate driving mechanism is installed in each horizontal sliding groove. The traction sleeve is set on the side and the traction block is set. The traction block is connected with a pull rope. In the hole, the lower end of the sleeve pipe and the lower end of the stay cord are connected to the fixed part and the moving part of the foot switch driving part, and the stay cord is controlled to move telescopically in the sleeve pipe through the foot switch. The present invention realizes the functions of synchronous deployment and merging of the pressing plate driving mechanisms on both sides through the foot switch, and the adopted pressing plate driving mechanism can realize the functions of unfolding and outward translation under the pedal driving. It brings great convenience to the page-turning operation of the music score, and is suitable for the use of music scores of various materials. The user can drive the unfolding and pressing with one hand to turn the page by stepping on the foot.

The invention discloses a graphene-modified antistatic TPU film, which is prepared from the following raw materials in parts by mass: 60-80 parts of polyether-type TPU resin, 1-3 parts of modified graphene, and 2-4 parts of thermal stabilizer , 1-3 parts of lubricant, 1-2 parts of plasticizer, and 0.5-2 parts of nano-alumina; after graphene oxide is modified by silane coupling agent and reduced by ammonia water, it is uniformly dispersed in TPU resin, and at the same time It does not polymerize itself, which enhances the electrical conductivity and impact resistance of the TPU film; after the nano-alumina is modified, the mechanical properties of the nano-alumina and the affinity for the resin material are enhanced; at the same time, the nano-alumina, graphite The amount of alkene is less, which reduces the production.

The invention discloses a digital onboard power supply output soft start method and belongs to the field of onboard electronic technology. The method comprises establishing an onboard power supply main circuit and an onboard power supply control unit, initializing a configuration function, completing a performance function, comparing a soft start counter with a set voltage reference value in orderto select either of the soft start counter and the set voltage reference value as a voltage external-loop voltage reference to be substituted into the voltage outer-loop PID calculation, thereby realizing the soft start of the onboard power supply, solving the technical problem of the soft start of the onboard power supply, and eliminating the defect that the onboard power supply, which is a switching power supply, has over-high and sharply increased output-end voltage so as to cause an output-end capacitor to be unable to sustain the excessive surge current. The method avoids the use of a soft start circuit, thereby reducing the volume of the onboard power supply and the manufacturing cost, avoiding the power consumption of the soft start circuit, improving the operating efficiency of the onboard power supply and realizing the controllable soft start time.

The invention discloses a detection method of a self-trapping threaded sleeve drilling bottom hole and anti-stretching and anti-twist values and aims to solve the problems that the prior self-trapping threaded sleeve drilling bottom hole detection method is tedious, stretching resistance is not detected, and potential safety hazards exist. The detection method of the self-trapping threaded sleeve drilling bottom hole and the anti-stretching and anti-twist values comprises the following steps: 1) drilling a bottom hole; 2) detecting the bottom hole by adopting a hole diameter detection device; 3) detecting verticality; and 4) detecting anti-stretching and anti-twist values of the a self-trapping threaded sleeve by adopting an anti-stretching and anti-twist value measurement device. The detection method of the self-trapping threaded sleeve drilling bottom hole and the anti-stretching and anti-twist values improves the percent of once installment pass of the self-trapping threaded sleeve, eliminates potential quality hazard, and reduces reworking and production cost.

The invention discloses an automatic cut-off machine comprising a main unit base, a feed mechanism, a discharge mechanism, a length limiting mechanism, a cutting mechanism, a compressing mechanism, a loading vehicle and an operating box. The feeding mechanism delivers an aluminum alloy profile to the discharge mechanism; after the aluminum alloy profile is in contact with a detection switch of the length limiting mechanism, discharging and feeding stop; the compressing mechanism pushes a pressure plate through a cylinder so as to fix and compress the profile; the cutting mechanism cuts the profile; after cutting, the length limiting mechanism pops up; the discharge mechanism delivers the cut profile to the loading vehicle; the length limiting mechanism pops down, and the feed mechanism moves to perform feeding. The automatic cut-off machine is simple in structure and low in manufacturing cost, has a wide cutting range, allows accurate cutting and has an automatic cutting mode and a manual step cutting mode.
