Description
Technical Field
[0001] This utility model relates to the field of machining tools, and in particular to a handheld screwdriver with laser alignment function. Background Technology
[0002] Handheld screwdrivers are widely used tools in the field of automated assembly, which can significantly improve the efficiency and consistency of screw fastening. As the manufacturing industry continues to demand higher assembly precision, especially in applications with complex structures, poor lighting, or densely packed holes, relying solely on the operator's naked eye to align the screw holes can easily lead to problems such as low efficiency and positioning errors.
[0003] To address this, an improved solution has emerged in the industry: integrating a laser alignment tool into a handheld screwdriver. By emitting a laser beam to create a visible spot on the workpiece, the position of the screw hole can be indicated intuitively and accurately, effectively solving the aforementioned alignment difficulties.
[0004] However, this handheld screwdriver integrating a laser alignment function has also revealed new structural deficiencies in practical use. As a precision optical component, the core lens of the laser alignment function is directly exposed to the working environment. During breaks from screwdriver operations, or during storage and handling, the lens is highly susceptible to contamination from dust, oil, and other pollutants in the workshop, or scratches and collisions with other objects. These external factors can cause the lens to become dirty or damaged, thus affecting the collimation and spot quality of the laser beam. In severe cases, it can even completely disable the laser alignment function, negating its original technological advantages. Therefore, a handheld screwdriver with laser alignment functionality is proposed to address these issues. Utility Model Content
[0005] In view of the problems in the existing handheld screwdrivers with laser alignment function, such as the integrated laser alignment lens being easily contaminated and damaged by collisions, leading to decreased alignment accuracy or functional failure, this utility model aims to provide a handheld screwdriver with laser alignment function with an improved structure that can effectively solve the above problems.
[0006] This utility model provides a handheld screwdriver with laser alignment function, including a power unit, a screwdriver, a connecting cable, a laser alignment device fixedly connected to the outer wall of the screwdriver, and a protective mechanism.
[0007] The protective mechanism is used to detachably protect the laser pointer, and includes a protective connecting ring fixedly connected to the outer wall of the laser pointer, and a protective cover that cooperates with the protective connecting ring.
[0008] Furthermore, a first magnetic ring is fixedly connected to the protective cover, and a second magnetic ring is provided inside the protective connecting ring. The protective cover is detachably connected to the protective connecting ring by the magnetic attraction between the first magnetic ring and the second magnetic ring. This magnetic attraction connection method makes it very convenient to install and remove the protective cover, while ensuring the firmness of the connection and preventing accidental detachment when not in use.
[0009] Preferably, a rubber sheet is fixedly connected to the inner side of the protective cover, and the rubber sheet is positioned facing the laser pointer. This rubber sheet allows for flexible contact with the lens end face of the laser pointer when the protective cover is closed, thus providing cushioning and sealing against dust, preventing damage to the lens from hard contact.
[0010] Preferably, a positioning locking ring is also fixedly connected to the protective cover. The structure of this positioning locking ring can provide structural guidance when the protective cover and the protective connecting ring are aligned, making the installation more convenient and accurate, and avoiding installation difficulties or poor sealing caused by misalignment.
[0011] Preferably, the handheld screwdriver with laser alignment function further includes a limiting mechanism, which is disposed on the power body to provide stable placement and fixation of the screwdriver when not in use.
[0012] Preferably, the limiting mechanism includes a limiting mounting bracket fixedly connected to the power unit, a limiting base plate, a support plate fixedly connected between the limiting mounting bracket and the limiting base plate, and a limiting ring disposed above the limiting base plate; the side wall of the support plate is provided with a spring, and the spring elastically abuts against the limiting ring. With this structural combination, when the screwdriver is placed, it can be clamped or supported and fixed by the elastic action of the spring and the limiting ring, resulting in a simple and reliable structure.
[0013] Preferably, the power unit is also equipped with a control panel. This control panel is integrated into the power unit, allowing operators to set and adjust the equipment's torque, speed, and other operating parameters before operation.
[0014] Preferably, the power unit is further provided with a top hinged cover, which is hinged to the top of the power unit. This structure facilitates the opening of the power unit's outer casing for internal maintenance, repair, or replacement of parts, thus improving the maintainability of the equipment.
[0015] Preferably, the power unit is also equipped with a storage box and a sliding sealing cover, the sliding sealing cover being slidably fitted onto the power unit and covering the storage box. The storage box provides integrated storage space for commonly used small accessories such as screwdriver bits, while the sliding sealing cover effectively prevents accessories from being lost or contaminated by dust, enhancing the overall integrity and ease of use of the equipment.
[0016] This utility model has the following beneficial effects:
[0017] 1.
