Technical Field

[0001] The utility model relates to the technical field of handheld automatic screw machines, in particular to a handheld automatic screw machine. Background Art

[0002] Handheld automatic screwdrivers are portable tools typically used to drive screws or bolts quickly and efficiently. They are often used on assembly lines, in assembly jobs, or in other applications where large numbers of screws are required to improve efficiency and reduce labor intensity. Operators simply align the tool with the screw hole and press a switch to drive the screw, significantly speeding up the process.

[0003] Some existing handheld automatic screw machines are usually equipped with a vertical arm, especially when driving bolts, to provide stable support and accurate positioning, so that the operator can accurately align the screw machine with the workpiece and perform the driving operation. However, when using the vertical arm to fix the screw machine, it is usually necessary to use a wrench or other tools to adjust the clamping part to ensure that the screw machine is fixed in the appropriate position. This results in extra time and tools required to complete these adjustments when disassembling and assembling the screw machine, which is very inconvenient. Therefore, those skilled in the art provide a handheld automatic screw machine to solve the problems raised in the above background technology. Utility Model Content

[0034] Working principle: In working situations where the vertical arm is required, when fixing the screw machine body 1, the clamping part of the vertical arm can be adjusted to fix the outer sleeve 3 outside the screw machine body 1 (the coverage area of ​​the clamping part is located in the upper area of ​​the fixed card slot 8), so as to complete the fixing operation of the screw machine body 1. At this time, when disassembling the clamped screw machine later, it is only necessary to press the fixed card block 7 to disengage it from the fixed card slot 8, so as to release the fixed connection between the screw machine body 1 and the outer sleeve 3, and then the screw machine body 1 can be directly pulled out from the outer sleeve 3. At the same time, when installing the screw machine body 1, it is only necessary to press the fixed card block 7 to retract it into the movable slot 6, so that the sliding card block 5 and the positioning card block 11 on the screw machine body 1 are smoothly inserted into the sliding card slot 4 and the positioning card slot 10, and then the fixed card block 7 is fixed via the provided return spring 9. It pops up, resets, and snaps into the fixed slot 8, so that the screw machine body 1 and the outer sleeve 3 are fixedly connected together. Since the outer sleeve 3 is fixed on the vertical arm at this time, the fixing operation of the screw machine body 1 on the vertical arm is completed. The whole process does not require the use of other tools, nor does it need to repeatedly adjust the clamping part of the vertical arm, thereby effectively improving the disassembly and assembly efficiency of the screw machine body 1, which is convenient and practical. When using the screw machine body 1, if the work is temporarily stopped, the rack 15 can be moved up by toggling the adjusting gear 14, so that the locking block 17 is stuck in the locking slot 18, and the switch 2 can be locked, thereby effectively preventing the screw machine body 1 from accidentally starting during non-working hours and causing adverse effects. When unlocking, it is only necessary to control the locking block 17 to disengage from the locking slot 18 by toggling the adjusting gear 14 in the reverse direction, thereby unlocking the switch 2.
