[0030] The use of the utility model:

[0031] First of all, it should be made clear that the fastening tool involved in the utility model is mainly used for tightening and removing screws. The utility model takes the installation of screws of various depths as an example to explain its use method in detail. When it is necessary to tighten the screw, first adjust the height of the adjustment part 200 to a suitable level according to the depth of the connecting hole between the two connected workpieces. The specific operation method is to loosen the hand-tightening bolt, press the adjusting part 200 inward or pull it outward to a suitable length, and then tighten the hand-tightening bolt to lock the position of the adjusting part 200 with the adjusted height, and then the screw tightening operation can be carried out. When the depth of the connecting hole is too deep and the height of the adjusting part 200 is adjusted to the longest and can no longer meet the use requirements, it is necessary to loosen the threaded rod with the help of an inner hexagonal wrench, and then rotate the fastening part 400 to adjust the relative length between the fastening part 400 and the extension rod to a suitable level, and then lock the threaded rod to lock the position of the extension rod, and then continue to tighten the screw. When the tightening force required is large, the operator inserts the limit rod at the lower part of the handle 500 into the handle 500. The utility model can realize the convenient and rapid adjustment of the working height of the fastening assembly through the cooperation of the gripping part 100, the adjusting part 200, the extending part 300 and the fastening part 400, and can conveniently and quickly adjust the tightening force during work to adapt to the operation, and can be disassembled and collected in a tool box, which is convenient for storage and carrying, and is more convenient to use. It solves the problem of carrying a large number of screw fastening tools when fastening different types of screws, which is very cumbersome, and it is impossible to perform convenient and rapid installation and fastening operations for screws with different installation depths and installation strength requirements. At the same time, the use of electric screw fastening tools, although it is convenient to replace the installation head, is inconvenient for users to carry due to its large size, and requires electricity to drive. Even if there is a battery, when the battery is exhausted and a power outage occurs, there is no way to use it, which brings certain troubles to the actual assembly work.
