When opening power gauge tap 4, silicon steel sheet and coil 6.5 energisings and rotation, drive left side lid 6.4 and right ratchet seat 6.25 rotations, by inside and outside ratchet 6.10,6.11,6.21,6.22, the gear drive of central gear 6.17 and inner spinous ring 6.20 cooperates, and makes left ratchet seat 6.6 rotate synchronously, is being shaped on the cingulum ratch 3 that is dynamically connected by left ratchet seat 6.6 front portions, connect ratch 3 and cooperate with drill bit 1, thereby drive drill bit 1 rotation by connector 2.
The electric hand drill speed change is outwards to be turned by speed-regulating switch 4, make speed governing push rod 6.26 outwards flick, speed governing alignment pin 6.15 drives right speed governing cover 6.16 motions under 6.2 effects of compression spring, owing to thereby the effect of center push rod 6.13 makes the speed governing cover 6.12 on the left side also simultaneously along with the motion campaign by speed governing cover 6.16, under the motion of speed governing cover 6.12,6.16 and big or small very heavy spring 6.9,6.23 cooperate, obtain speed change, thereby obtain different drill speeds.
Because under the effect of very heavy spring, very heavy during with the interlock of sour jujube circle, the sour jujube circle is rotated, but when making the opposite spin of sour jujube circle not transmission speed and power, thereby the generation skidding; When very heavy relieving, the sour jujube circle then can not rotate, and also can produce skidding, when speed governing cover 6.12,6.16 is on the central shaft 6.14 the through hole upper end position, big very heavy and left handle ratchet wheel 6.11 interlocks in a left side, right big very heavy and right outer ratchet 6.22 interlocks, be slow shelves transmission speed this moment.When speed governing cover 6.12,6.16 is on the central shaft 6.14 the through hole centre position, big very heavy and preceding handle ratchet wheel 6.11 interlocks in a left side, the big very heavy relieving in back is middle-grade transmission speed at this moment.When speed governing cover 6.12,6.16 is on the central shaft 6.14 the through hole lower end position, about big very heavy full relieving, be fast grade transmission speed this moment.Concrete drive connection is as follows:
1, the transmission of slow shelves: silicon steel sheet and coil 6.5 drive right ratchet seat 6.25 rotations in the rotor, right big very heavy and right outer ratchet 6.22 interlocks, right little very heavy skidding, then right ratchet seat 6.25 drives right outer ratchet 6.22 rotations, passing through inner spinous ring 6.20, the transmission of central gear 6.19 cooperates, drive the inside and outside ratchet 6.10 in a left side, 6.11 rotate, and big very heavy and left handle ratchet wheel 6.11 interlocks in left side this moment, little very heavy and left outer ratchet 6.10 interlocks in a left side, but because very heavy effect, the outer ratchet 6.10 in a left side skids, and left handle ratchet wheel 6.11 rotates, thereby left handle ratchet wheel 6.11 drives the transmission of the slow shelves of left ratchet seat 6.6 outputs, again by connecting the transmission of ratch 3, makes the slow shelves of drill bit 1 output speed.
2, middle-grade transmission: silicon steel sheet and coil 6.5 drive right ratchet seat 6.25 rotations in the rotor, right big very heavy relieving, right outer ratchet 6.22 skids, right little very heavy and right handle ratchet wheel 6.21 interlocks, then right ratchet seat 6.25 drives right handle ratchet wheel 6.21 transmissions, passing through inner spinous ring 6.20, the transmission of central gear 6.19 cooperates, drive the inside and outside ratchet 6.10 in a left side, 6.11 rotate, and big very heavy and left handle ratchet wheel 6.11 interlocks in left side this moment, the little very heavy relieving in a left side, because very heavy effect, the outer ratchet 6.10 in a left side skids, and left handle ratchet wheel 6.11 rotates, thereby left handle ratchet wheel 6.11 drives the equal rotating speed of left ratchet seat 6.6 outputs, by connecting the transmission of ratch 3, make the middle-grade speed of drill bit 1 output again.
3, the transmission of fast shelves: silicon steel sheet and coil 6.5 drive right ratchet seat 6.25 rotations in the rotor, right big very heavy relieving, right outer ratchet 6.22 skids, right little very heavy and right handle ratchet wheel 6.21 interlocks, then right ratchet seat 6.25 drives right handle ratchet wheel 6.21 transmissions, passing through inner spinous ring 6.20, the transmission of central gear 6.19 cooperates, drive the inside and outside ratchet 6.10 in a left side, 6.11 rotate, and the big very heavy relieving in left side this moment, little very heavy and outer ratchet 6.10 interlocks in a left side in a left side, but because very heavy effect, left side handle ratchet wheel 6.11 skids, and the outer ratchet 6.10 in a left side rotates, thereby the outer ratchet 6.10 in a left side drives the transmission of the fast shelves of left ratchet seat 6.6 outputs, by connecting the transmission of ratch 3, make the fast shelves of drill bit 1 output speed again.
