As shown in fig. 1 and 2,

pins

1 and 2 of the power input terminal of the power module U1 and two poles of the ac 220V power supply are connected by wires, respectively, and pins 3 and 4 of the power output terminal of the power module U1,

pins

1 and 2 of the power input terminal of the power switch S, and one end and the other end of the power input terminal resistor R3 of the display mechanism are connected by wires, respectively. The power output ends 5 and 6 of the power switch S, the two normally closed contact ends of a power output end relay K1 of the control prompt circuit and the negative and positive and negative pole power input ends of the electric push rod M are connected through leads, and the two wiring ends of the adjustable resistor RP are connected in series between one end of a signal input end resistor R3 of the display mechanism and the 3 pins of the power module U1 through leads.

When measuring bamboo head end external diameter, an staff takes up bamboo middle part and puts the front end in fixed slot 102, then another staff stirs switch S 'S handle left, then switch S' S1, 2 feet and 3, 4 feet communicate respectively, and like this, electric putter M 'S positive and negative poles can be got electric (12V power through two control power input ends of relay K1, two normally closed contact ends get into electric putter M' S positive and negative poles power input end), electric putter M 'S movable rod then promotes contact ring 103 downstream, the simultaneous gangbar 104 drives adjustable resistance RP' S handle downstream, contact ring 104 contacts with bamboo end upper portion gradually. In practical situations, after the lower part of the contact ring 104 and the stress surface of the force sensitive resistor RT do not effectively contact the upper part of the bamboo end, because the reverse acting force is small, the pressure generated by the stress surface of the force sensitive resistor RT is small, the resistance value is large, the voltage division is large, and the voltage division by the resistor R1 is small, thus, after the 12V power supply is subjected to the voltage division by the force sensitive resistor RT and the resistor R1, the voltage of a control electrode entering the silicon controlled rectifier VS is lower than 0.8V through the current-limiting voltage reduction of the resistor R2, the silicon controlled rectifier VS cannot be triggered and conducted, the relay K1 keeps a power-off state, and the movable rod of the electric push rod M continuously pushes the contact ring 103 and the force sensitive resistor RT to go down. In practical situations, after the lower part of the contact ring 104 and the stress surface of the force sensitive resistor RT effectively contact the upper part of the bamboo end, due to the large reverse acting force, the pressure generated by the stress surface of the force sensitive resistor RT is large, the resistance value is small, the voltage division is small, and the voltage division is large through the resistor R1, thus, after the 12V power supply passes through the force sensitive resistor RT and the resistor R1, the voltage of the control voltage entering the silicon controlled rectifier VS is higher than 0.8V through the resistor R2 for current limiting and voltage reducing, the silicon controlled rectifier VS can be triggered and conducted, further, the relay K1 is electrified to attract the two control power supply input ends and the two normally closed contact ends to be open, the movable rod of the electric push rod M does not continuously push the contact ring 103 and the force sensitive resistor RT to go down, the buzzer B can still generate electricity to generate sound after the silicon controlled rectifier VS is conducted, another worker is prompted, and the number displayed by the voltmeter V is used for obtaining and recording the outer diameter of the bamboo end of the bamboo to be measured. After the external diameter of one of them bamboo end has been measured, the staff stirs switch S 'S handle right, then switch S2' S1, 2 feet and 5, 6 feet communicate respectively, like this, electric putter M 'S the negative and positive two poles can be electrified, electric putter M' S movable rod then drives contact ring and force sensitive resistor RT upward movement (buzzer B loses the electricity and does not sound again at this moment), and the measuring bamboo pulls open the interval, the staff just can take out the measuring bamboo, get into the next bamboo external diameter measurement process that is located on the bamboo heap.

Fig. 1 and 2 show, in this novel, its resistance value can take place the synchronous change when the handle of contact ring drive adjustable resistance RP descends, like this, the voltage that gets into voltmeter V can change, it is more (representing that bamboo end external diameter is less) that adjustable resistance RP's resistance value is less and with resistance R3 between the partial pressure little down, voltage signal that gets into voltmeter V after resistance R4 current-limiting step-down is less, the digit that the voltmeter shows is less represents that bamboo end external diameter is less, otherwise is bigger. The utility model discloses, resistance R4 can adopt adjustable resistance to replace, in production, when the technical staff passes through the different resistance values of adjusting this adjustable resistance, can accurate regulation voltmeter correspond bamboo end external diameter data (adjust the external diameter of good check-up bamboo of vernier caliper survey before, serve the back when the contact ring lower extreme effective contact bamboo, the technical staff adjusts the resistance value of this adjustable resistance repeatedly, just adjust the digit that the voltmeter shows and when bamboo end external diameter is unanimous (for example bamboo end external diameter 12.85 centimetres, the voltage digit that the voltmeter shows is 12.85V), this adjustable resistance's resistance value just adjusts and targets in place, then this adjustable resistance's resistance value is measured to the outage, the resistance value that records is when just follow-up batch production product, resistance R4's resistance value (or adopt adjustable resistance to adjust and target in place in advance). Through the aforesaid, this novel staff only need put the bamboo head end between fixed slot and contact ring in, then operation switch just can measure the external diameter of bamboo front end, can stop motion and send the pronunciation suggestion measuring staff to read under the control suggestion circuit effect after the contact ring targets in place down during the measurement, like this, the staff just can directly perceivedly draw the external diameter of bamboo end through watching the digit that shows table demonstration, and then, can accomplish the external diameter measurement of bamboo end automatically, this is novel has brought the facility for the staff, and has improved measurement of efficiency.
