Embodiment 1

[0029] An adjustable pneumatic multifunctional screwdriver for construction engineering, such as figure 1 As shown, it includes a first frame body 1, a second frame body 2, a third frame body 3, a switch mechanism 4 and a rotation mechanism 5, and the rear side of the first frame body 1 is provided with a second frame body 2, and the second frame body 2 A third frame body 3 is provided on the rear side, a switch mechanism 4 is provided on the first frame body 1, and a rotation mechanism 5 is connected between the second frame body 2 and the third frame body 3.

[0030] When the user needs to use a screwdriver, the screwdriver can be used. The user can first connect the screwdriver to the air pump, then turn on the switch through the switch mechanism 4, and then start working through the rotating mechanism 5. When the user does not need to use the screwdriver, through The switch mechanism 4 can be closed.

Embodiment 2

[0032] On the basis of Example 1, such as figure 2 and image 3 As shown, the switch mechanism 4 includes a first isolation plate 41, a barrier ball 42, a linear spring 43 and a push switch 44. The lower side of the first frame body 1 is provided with a first isolation plate 41, and the first isolation plate 41 is provided with a slide type. There are two blocking balls 42 , the first frame body 1 is provided with a sliding push switch 44 , and a linear spring 43 is connected between the pressing switch 44 and the two blocking balls 42 .

[0033] The user can connect the air pump to the lower part of the first frame body 1. When the user needs to turn on the switch, he can press the push switch 44 to the inside, and the push switch 44 drives the barrier ball 42 to move forward, so that the two barrier balls 42 do not move forward. Block the first isolation plate 41 again, and now the linear spring 43 is compressed, so that the air pressure generated by the air pump enters th...

Embodiment 3

[0037] On the basis of Example 2, such as Figure 4-9 As shown, a flow control mechanism 6 is also included, and the flow control mechanism 6 includes a first connecting rod 61, a lower wedge 62, an upper wedge 63, a second isolation plate 64, a stopper 65 and a first placement frame 66, press The upper part of the switch 44 is provided with a first connecting rod 61, the upper part of the first connecting rod 61 is provided with a lower wedge-shaped block 62, the first frame body 1 is covered with a first placement frame 66, and the top of the first placement frame 66 is provided with a stopper 65 , the first placement frame 66 is slidingly provided with a second isolation plate 64 , the second isolation plate 64 is connected with an upper wedge block 63 , and the upper wedge block 63 cooperates with the lower wedge block 62 .

[0038] When the push switch 44 moves inwardly, it drives the first connecting rod 61 and the lower wedge 62 to move inwardly, so that the lower wedge 6...

Abstract

The invention relates to a screwdriver, in particular to an adjustable pneumatic multifunctional screwdriver for constructional engineering. The technical problem to be solved is to provide the adjustable pneumatic multifunctional screwdriver for constructional engineering which can automatically tighten a screw and can change the direction of a screw rotating head. The adjustable pneumatic multifunctional screwdriver for constructional engineering comprises a first frame body, a second frame body, a third frame body and a switching mechanism, wherein one first frame body is arranged, the second frame body is arranged on one side of the first frame body, the third frame body is arranged on one side of the second frame body, and the switching mechanism is arranged on the first frame body. The screwdriver can achieve effects that a screw can be automatically tightened, and the direction of the screw rotating head can be changed, a rotating disc is manually rotated, then a first gear is meshed with a rack, a second connecting rod drives a baffle to move up and down, and the rotating direction of fan blades is changed, so that the direction of the screw rotating head can be changed.

Description

technical field [0001] The invention relates to a screwdriver, in particular to an adjustable pneumatic multifunctional screwdriver for construction engineering. Background technique [0002] A screwdriver is a tool that helps a screw turn into place. It usually consists of a handle and a thin wedge-shaped head, which is inserted into the groove of the screw through the thin wedge-shaped head to tighten the screw. [0003] When people use a general screwdriver, they generally manually clamp the head of the screwdriver in the groove of the screw, then manually hold the handle of the screwdriver, and apply force to the screwdriver to tighten the screw. In this way, the screw needs to be manually tightened vigorously, and the screw cannot be guaranteed to be screwed in place. [0004] Therefore it is necessary to design a kind of adjustable pneumatic multifunctional screwdriver that can automatically tighten the screw and can change the direction of the screw turning head. ...
