摘要:
A light single button multi-function electric hammer comprises a body, a motor, a rotation set assembly (1), a cylinder assembly (6), a torque spring (2), a knob (26), a gearwheel and a transmission mechanism of torque clutch. The transmission mechanism of torque clutch comprises a pinion (7), a gear clutch (8), a middle shaft (10), a hammer crosspiece clutch (9), a swing rod bearing (11) and a primary gear (12). The pinion is movably fitted with the middle shaft; the pinion meshes the large end teeth of the gearwheel and matches with the inner teeth of the gear clutch. The gear clutch meshes the small end teeth of the gearwheel and is fitted with the teeth shaft of the middle shaft. The gear clutch and the hammer crosspiece clutch are movably fitted with the teeth shaft of the middle shaft. The swing rod bearing is movably fitted with the middle shaft and is connected with the cylinder assembly through the swing rod. Matched concavo and convex slots are set on the hammer crosspiece clutch and swing rod bearing. The primary gear is tightly fitted with the middle shaft. The knob is connected with an operating mechanism linked to the large teeth end of the gearwheel, the gear clutch and the hammer crosspiece clutch. The electric hammer enables a simple and compact structure, flexible and convenient conversion, low cost, safe and reliable use.

[Problem] To provide a hammer drill improved for enhanced drilling performance. [Solution] A hammer drill having: a linear impact mechanism section (115) for applying an impact force in the longitudinal axis direction to a tool bit (119); and a rotational drive mechanism section (117) for rotationally operating the tool bit (119) about the longitudinal axis. The hammer drill is configured so that a rotational impact can be applied to the tool bit (119) in the rotational direction.

摘要:
The invention relates to a hand-held power tool device, in particular a hammer drill and/or chisel hammer device, comprising at least one operating element (10a-f, 11a-d) and at least one locking unit (12a-f), which comprises at least one locking element (14a-f, 54d), which can be moved from at least one storage position into at least one locking position and vice versa and locks the operating element (10a-f, 11a-d) in at least one operating state in the locking position. The locking unit (12a-f) has at least one controllable actuator element (16a-f) for influencing motion of the locking element (14a-f, 54d).
摘要:
An electric power tool (2) of one aspect of the present disclosure includes a housing (10), a motor (8), an output shaft (6, 30), a first power transmission (40), a second power transmission (20, 30), a common sensor (92; 90A), a twisted-motion detector (94), and a vibration-based load detector (94). The common sensor (92; 90A) detects a motion of the housing (10) and outputs a detection signal indicating the detected motion. The twisted-motion detector (94) detects a twisted-motion of the housing (10) in a circumferential direction of the output shaft (6, 30) based on the detection signal. The vibration-based load detector (94) detects a vibration of the housing (10) in an axial direction of the output shaft (6, 30) based on the detection signal and detects a load on the output shaft (6, 30) based on the detected vibration.
