The following describes a method of using the self-locking multifunction tool.

As shown in fig. 15, the tool head assembly S is positioned at the outer side edge of the sliding groove 221, and the handle 3 is still retracted in the sleeve 2.

When the user needs to use the tool head 5, the user can use a finger to toggle the toggle protrusion 72 of the toggle head 7, so that the toggle head 7 slides towards the inner side of the sliding groove 221. Since the T-shaped connecting protrusion 63 is engaged in the sliding channel 731, the sliding head 6 and the tool bit 5 on the sliding head 6 slide synchronously with the striking head 7 until the whole tool bit assembly S moves to the center of the sleeve 2, i.e. the screw head limiting groove 35 of the handle 3, as shown in fig. 16. At this time, the user pushes the tail of the handle 3, so that the handle 3 moves forward, and the user can adjust the protruding depth of the tool head 5 by matching the spring pin 4 with the adjusting clamping holes 201 at different positions, thereby being suitable for different operating environments. As shown in fig. 17, the spring catch 4 now snaps into a foremost one of the adjustment catch holes 201, at which point the elongation of the tool head 5 is at its maximum.

Since the magnet is provided in the tool mount 62 of the slide head 6, the slide base 61 of the slide head 6 is simultaneously attracted to the screw head stopper groove 35 when the tool head 5 is extended. When the user rotates the sleeve 2 and drives the tool bit 5, the sliding base 61 will not rotate in the bit-limiting groove 35, and at the same time, the tool bit 5 will not rotate in the tool-locking notch 62. By using the square main groove 351 and the triangular auxiliary groove 352 of the screw head limiting groove 35, the sliding head 6 of any one tool head assembly S on the eight sliding grooves 221 can be clamped into the screw head limiting groove 35. In addition, a magnet may be disposed in the screw head limiting groove 35 for improving the connection firmness.

When the tool is not needed to be used, the positioning steel ball 42 on the spring pin 4 is pressed to press the tool head 5 against the table top, and the handle 3 is pushed into the sleeve 2. When the spring pin 4 is pushed into the most proximal one of the adjustment card holes 201, the tool head assembly S returns to the initial position. Then, the user again dials the dial protrusion 72 of the dial head 7, so that the dial head 7 slides to the outside of the sliding groove 221, and returns to the storage position as shown in fig. 15.

Eight different tool bits can be accommodated at a time by using the eight slide grooves 221. Because the tool head 5 and the sliding head 6 are connected by magnetic attraction, a user can also quickly replace other tool heads of more types, and the use is convenient. The self-locking multifunctional tool is integrally cylindrical, does not have any protruding tip, cannot puncture clothes even if being placed in the pocket, and is convenient to carry.
