20100044063 | Vibratory and Impact Connector for a Power Tool - A vibratory and impact connector for a power tool is provided with a spring, a first drive rod, a drive ring and a second drive rod which are sequentially received in an outer cylinder. The first drive rod is inserted through the spring and extended out of the outer cylinder, the second drive rod is inserted through the drive ring and into the first drive rod, and the drive ring is fixed to the outer cylinder. By such arrangements, driving the second drive rod can rotate the outer cylinder, the first drive rod and the drive ring. Furthermore, by restricting the rotation of the outer cylinder, the drive ring can also be restricted from rotation, and the drive ring and spring can cooperate with a spring to drive the first drive rod to perform axial reciprocation, thus creating an impact operation. | 02-25-2010 |

20090000432 | Tool Head Structure - A tool head structure is used to screw a general screw or screw a damaged screw and comprises two cutting edges located at the center of the front end thereof. Between the two cutting edges is formed a ridge line, at the central axis of the tool head structure is formed a chisel point, and behind the two cutting edges are formed two concave flank portions, and each flank portion is correspondingly linked up with the concave engaging portion. By such arrangements, the tool head structure of the present invention can solve the problem of easy slipping and being unable to remove the damaged screw. | 01-01-2009 |
20110127054 | Chisel Adapter - A chisel adapter has both ends connected with a tool head and a drive tool, respectively, and comprises: a first sleeve, a slide bushing, a first fastener, an abutting member, a second sleeve, a first rod, and a second rod. The chisel adapter is convenient to use since it allows the user to replace the chisel by hand without using tools. Furthermore, the chisel adapter is improved in applicability since it is applicable to common drive tools. | 06-02-2011 |

20130001897 | CONNECTING ROD ASSEMBLY FOR CONNECTING A WORK HEAD - A connecting rod assembly is capable of pushing the work head outward to allow more of the part of the work head to be exposed out of the connecting rod assembly, making it easier for the user to pull out the work head, thus solving the problem that it is difficult to pull the work head out of the conventional connecting rod structure since the conventional connecting rod structure doesn't have any function or devices to move the work head outwards. | 01-03-2013 |

20150042358 | Dielectric Constant Measurement Circuit and Dielectric Constant Measurement Method - A dielectric constant measurement circuit includes a dielectric constant sensor, an oscillator controlling circuit, a waveform converting circuit, and a counting readout circuit. The oscillator controlling circuit generates an oscillation waveform according to the response of the dielectric constant sensor to a dielectric material. The waveform converting circuit converts the oscillation waveform into frequency division square waves. The counting readout circuit includes a switching counter, a switching circuit, a reference current source, and a current integrator. The reference current source charges the current integrator through the switching circuit controlled by the frequency division square waves, and the switching counter counts the number of the turned-on states of the switching circuit and stops counting the number of the turned-on states when a value of the output voltage from the current integrator reaches a value of the reference voltage, and the number of the turned-on states is related to the oscillation frequency. | 02-12-2015 |
