The top block 42 is provided with a second rotating groove 412 to accommodate the second rotating shaft 421, and the second rotating groove 421 is C-shaped. The protruding part 422 is arranged on one side of the top block 42, which is away from the central axis of the main rod 1, and the protruding part 422 is provided with an obtuse angle structure which can enter the inner angle of the inner hexagon screw, and the obtuse angle structure is matched with the inner angle of the inner hexagon screw, so that the top block 42 can be tightly attached to the inner angle of the inner hexagon screw when being propped against the inner angle of the inner hexagon screw, and the inner hexagon screw is prevented from being separated from the inner hexagon screw when the inner hexagon screw is loosened. Specifically, as shown in fig. 6, the horizontal projection of the top block 42 is composed of a rectangle and an isosceles obtuse triangle, and one of the long sides of the rectangle is co-located with the hypotenuse of the isosceles obtuse triangle, and the obtuse angle of the isosceles obtuse triangle is 120 °.
In this embodiment, the rotary rod 2 is a hollow screw, and the head thereof is exposed outside the other end of the main rod 1, and the rotary rod 2 is rotated by holding the head.
Specifically, the total length of the main rod 1 is 60mm, wherein the head part is a hexagonal nut with the length of 15mm and the length of 10mm, and the rest part is an inner hexagon with the length of 50mm and the length of 10 mm. The first rotating shaft 411 of the swing arm 41 is 2.7mm long, the diameter is 0.8mm, the locking plate 6 is fixed in the locking groove 11 of the main rod 1 by using an M1 screw with the length of 2.5mm, and the locking groove 11 is partially surrounded to form a first rotating groove 12 for accommodating the first rotating shaft 411.

The screw rod 2 is a hollow screw with the model of 6mm and the length of 60mm, the pressing rod 3 is a cylinder with the length of 60mm and the diameter of 2mm, and the diameter of the top surface of the pressing head 31 is 4mm.
The invention discloses an operation method of an internal hexagonal wrench based on the integration of multiple types, which comprises the following steps:
1. the swing arm assemblies 4 at one end of the main rod 1 are mutually closed and inserted into the inner hexagonal groove of the inner hexagonal screw;
2. rotating the rotary rod 2, so that the rotary rod 2 drives one end of the compression rod 3 to move towards one end of the main rod 1 and pushes each swing arm assembly 4, and each swing arm assembly 4 is spread until each swing arm assembly 4 respectively abuts against the corresponding inner angle of the hexagon socket head cap screw;
3. the main rod 1 is rotated, and the hexagon socket head cap screws are driven to rotate through the swing arm assemblies 4 so as to screw or unscrew the hexagon socket head cap screws.
Specifically, when the rotary rod 2 is rotated by hand to drive the compression bar 3 downwards during operation, the pressing head 31 is made to prop the bottom swing arm assembly 4, the protruding part 422 of the jacking block 42 is made to prop up to the inner angle of the inner hexagon screw, at this moment, the swinging arm 41 can not rotate any more because the pressing head 31 firmly clamps the swinging arm 41, at this moment, the protruding part 422 of the jacking block 42 is tightly attached to the inner angle of the inner hexagon screw, no gap exists between the protruding part 422 and the inner hexagon screw, so that the rotary rod is firmly clamped with the inner hexagon screw, and the head nut of the main rod 1 can be rotated by a wrench or a torque wrench to tighten the inner hexagon screw with ease. As shown in fig. 3, when the two swing arms 41 are abutted together toward the inner end angle of the main rod 1, the invention can tighten the socket head cap screw with minimum, specifically, against and tightening the socket head cap screw of 2 mm. As shown in fig. 4, the rotation of the rotary rod 2 drives the pressing rod 3 to move downwards, so that the pressing head 31 gradually opens the swing arm assembly 4, and the size of the inner hexagon screw capable of being loosened is changed. As shown in fig. 5, when the top end of the ram 31 contacts the swing arm assembly 4, the size of the inner hexagonal screw which can be loosened is the largest, and in particular, the inner hexagonal screw of 10mm can be supported and loosened. As can be seen from the above, the invention can be used for tightening the socket head cap screws with any size between 2mm and 10 mm.
In actual operation, because the inner diameters of the hexagon socket screws of 2mm and 2.5mm are smaller, only two swing arm assemblies 4 can be used when the hexagon socket screws are loosened, and the rest four swing arm assemblies 4 are expanded to the maximum, so that the hexagon socket screws are loosened by only using the two swing arm assemblies 4 to prop against the inner angles of the hexagon socket screws, as shown in fig. 9 and 10. Since the hexagon socket head cap screws of 2mm and 2.5mm do not need too much torque force, two swing arm assemblies 4 are used.
When the inner hexagon screws with the diameter of 3-4mm are loosened, only three swing arm assemblies 4 are needed to be used for propping against the inner corners of the inner hexagon screws for loosening, and the other three swing arm assemblies 4 are idle, as shown in fig. 11 and 12. Because the 3-4mm socket head cap screws do not need too much torsion, the three swing arm assemblies 4 are used for opening to be tight enough.
When the inner hexagon screws with the length of 5-10 mm are loosened, the six swing arm assemblies 4 can be fully placed into the inner corners of the inner hexagon screws to be loosened, and as shown in fig. 13 and 14, the six swing arm assemblies 4 can fully meet the corresponding torsion requirements.
If more complex working scenes are needed, three inner hexagonal wrenches can be prepared simultaneously to respectively cope with the three situations.
According to the multi-type integrated socket head wrench and the operation method thereof, the pressing head can downwards and gradually prop up the swing arm assembly to meet the use requirements of socket head screws with different sizes, so that the working efficiency is improved, the swing arm assembly can be enabled to prop against the inner angle of the socket head screw again through rotating the rotating rod for the socket head screw which is expanded and deformed, sliding teeth of the socket head screw are not easy to cause, the jacking block can be tightly attached to the inner angle of the socket head screw, the socket head wrench is firmer when the socket head screw is loosened, and the socket head wrench is not easy to separate from the socket head screw. Due to the tension of the swing arm assembly, the inner hexagon screw can be directly taken out through the swing arm assembly after being screwed down, and the problem that the inner hexagon screw is difficult to find after being loosened can be avoided.
Example two
Referring to fig. 15-16, a multi-type integrated socket wrench and an operation method thereof according to the present invention are different from the first embodiment in that the horizontal projection of the top block 42 is composed of a trapezoid and an isosceles obtuse triangle, and the bottom side of the trapezoid is co-bordered with the hypotenuse of the isosceles obtuse triangle. When the six swing arm assemblies 4 are all used, the distance between the six swing arm assemblies 4 is reduced to the minimum, and the side surfaces of the two adjacent jacking blocks 42 can be attached, so that the six swing arm assemblies 4 can be used for tightening smaller socket head cap screws, and the socket head cap screws with the length of 4mm can be propped up and tightened.
The invention relates to a multi-type integrated socket head wrench and an operation method thereof, and parts not related to the socket head wrench are the same as or can be realized by adopting the prior art.
