Embodiment Construction

[0039] Refer to attached figure 1 As shown, the fastener tool according to the first embodiment of the present invention includes a housing, a power device, a transmission device, an output device, a switch device and a switching device. The housing design includes typical hand-held power tool forms, eg, horn, gun or palm. The power device includes a motor 2 and a battery part arranged in the casing 1 . The switch device is disposed on the handle portion of the housing 1 and is operable to control the start and stop of the motor 2 . As a modification, the switch device can be a presser, and the presser is linked with the output device, and the start of the motor 2 is controlled by the pressing action. The depressor is operable to control the rotational speed of the motor 2, specifically through the force of the depressing action. If the depressing force is high, the motor rotational speed or torque will increase; if the depressing force is small, the motor rotational speed o...

Abstract

The invention discloses an output device of a fastener tool. The output device can be switched between at least two working modes. In a first working mode, the output device can non-rotatably move back and forth in the axial direction; and in a second working mode, the output device can rotatably move in the circumferential direction, with torque being intermittently increased. In the first working mode, the output device drives a hitting force transmission part which is used for transmitting hitting fore; and in the second working mode, the output device drives a rotation transmission part which is used for transmitting torque. The output device of the fastener tool disclosed by the invention can be adaptive to different fasteners such as screws, bolts and nails by switching the working modes; and not only can the inconvenience in continuously changing tools during working be avoided and the working efficiency of operators be improved, but also the functions of multiple tools are realized through one tool, the tool cost is greatly saved and the economic benefit is remarkable.

Description

technical field [0001] The invention belongs to the field of hand-held power tools, and in particular relates to a fastener tool used for fastening bolts, nails, etc., especially an output device in the aforementioned fastener tool. Background technique [0002] In the process of manufacturing wooden furniture and building wooden houses, fasteners such as screws, screws, bolts and nails are often used. At present, different hand tools or hand-held electric tools are generally used to work on the above fasteners, such as , use an electric screwdriver to drive screws and screws, use an electric wrench to drive bolts, and use an electric hammer to strike nails. However, these tools generally can only act on one kind of fasteners, for example, electric hammers can only be used to knock nails but not to screw screws, therefore, in the actual work process, the operator needs to frequently change tools to adapt different fasteners. The present invention designs and proposes a fas...
