Problems solved by technology

[0003] In order to overcome the deficiency that the existing screwdriver cannot better transform the cross-shaped screwdriver, the present invention provides a cross-shaped screwdriver with automatic telescopic transformation. The screwdriver not only combines the two to fix the metal strip so that it is not easy to fall off, but also can Convenient auto-scaling for free swapping

Embodiment Construction

[0010] exist figure 1 Among them, in the insulating handle 9, three indexing claws 2 with the same gap width as the sliding claws protruding from the sliding claw sleeve 3 are rotated, and a hand-pressed push rod 1 with the same width bead is also placed, and the compression spring is placed one the outside of the word metal knife, and make the sliding claw cover cover the word metal knife, press the push rod to make the sliding claw 10 leave the groove and slide along the inclined surface that it contacts, so that the sliding claw that is protruding from the sliding claw sleeve 3 slides on the In the gap between each indexing claw 2, due to the elastic force of compression spring 4, flat metal knife 5 is retracted, and the cross metal head of cutting is also due to the small spring 6 in connecting insulating handle 9 bottoms together.

[0011] exist figure 2 Among them, when the push rod 1 is pressed down, the bead on the push rod will press the sliding claw 10 in the axial...

Abstract

The invention discloses a screwdriver capable of switching between a line shape and a cross shape freely by stretching and retracting automatically. According to the screwdriver, a pipe is arranged in a cross-shaped metal blade, a line-shaped metal blade is placed in the pipe, the line-shaped metal blade is sleeved with a sliding claw sleeve, the sliding claw sleeve is sleeved with a spring, and the connection effect between a sliding claw of the sliding claw sleeve, a pressing strip of a hand-pressing push rod and an indexing claw enables the line-shaped metal blade to stretch and retract freely on a cross-shaped metal head which is cut open. Moreover, the cross-shaped metal head is connected with the bottom of an insulated handle through a small spring in the pipe of the cross-shaped metal blade so that the small hinge connecting pipe and the metal head which is cut open can be combined.

Description

Technical field: [0001] The invention relates to a screwdriver device capable of screwing, in particular to a screwdriver capable of automatic expansion and contraction and random conversion of a cross-shaped screwdriver. Background technique: [0002] At present, the known screwdriver is composed of an insulating handle, a flat metal knife or a cross metal knife. When it is necessary to twist the flat screw or the cross screw, the corresponding screwdriver is screwed, so that both become isolated. The two items are inconvenient to carry and increase the construction time. There are also metal strips with a letter at one end and a cross at the other end, which can be taken out for replacement, but this not only cannot fix the insulating handle to the metal strip, but also easily causes the metal strip to fall off on the insulating handle, and also increases the trouble and construction time in replacement. Invention content: [0003] In order to overcome the deficiency th...
