specific Embodiment approach 1

[0030] Specific implementation mode 1. Combination figure 1 Description of this embodiment, the combined hexagonal wrench device includes a handle 1, the shape of the handle 1 is a T-shaped structure, and the connection end is an external flower-shaped interface 11. It is characterized in that it also includes an adapter 2, and the adapter 2 is mainly composed of a sleeve Tube 3, mandrel 4, push rod 5, slip ring 6, compression spring 7 and inner wrench 8, handle 1 and sleeve 3 are connected through a flower-shaped interface, mandrel 4, compression spring 7, and inner wrench 8 are installed on Inside the sleeve 3, the slip ring 6 is installed outside the sleeve 3, the mandrel 4 is connected with the inner wrench 8 through a chute, the push rod 5 is connected with the mandrel 4 through a round hole, and the slip ring 6 is connected with the push rod 5 through a screw. The compression spring 7 is located in the gap between the inner wrench 8 and the sleeve 3 , one end of the comp...

specific Embodiment approach 2

[0048] Embodiment 2. The difference between this embodiment and Embodiment 1 is that this embodiment is a specific working process of Embodiment 1.

[0049] In the free state, the inner wrench 8 does not protrude from the sleeve 3, and the inner wrench 8 can be adjusted to extend or retract the sleeve 3 by changing the position of the slip ring 6 on the sleeve 3. When the inner wrench 8 extends out of the sleeve 3, the inner wrench 8 can be used to fasten or disassemble the corresponding hexagon socket head screw; when the inner wrench 8 is retracted into the sleeve 3, the outer wrench interface on the sleeve 3 can be used 33 to fasten or remove the corresponding hexagon socket head cap screws, and the function of the outer wrench interface 33 is equivalent to that of the outer wrench.

[0050] When using the inner wrench 8, first push and pull the slip ring 6, drive the push rod 5 to slide in the F-shaped chute 34, and drive the mandrel 4 and the inner wrench 8 to slide in the ...

Abstract

The invention discloses a combined internal hexagonal spanner device which relates to the technical field of combined spanners and solves the problems that the pressure of the spanner on a hand of a person in the prior art is large, and the flexibility is bad as each type of internal hexagonal spanner only fastens and detaches internal hexagonal bolts in one specification. The device comprises a handle and an adapter. The handle adopts a T-shaped structure, and the connection end is an external pattern interface. The adapter consists of a sleeve, a core shaft, a push rod, a sliding ring, a press spring and an inner-side spanner. The handle is connected with the pattern interface through the sleeve; the core shaft, the press spring and the inner-side spanner are all installed in the internal part of the sleeve; the sliding ring is installed on the external part of the sleeve; the core shaft is connected with the inner-side spanner through a sliding groove; the push rod is connected with the core shaft through a circular hole; the sliding ring is connected with the push rod through a bolt; and the press spring is located in a gap between the inner-side spanner and the sleeve. The combined internal hexagonal spanner device can adopt the adapters in different specifications, the inner-side spanner and the external spanner interface of each kind of adapter respectively correspond to the internal hexagonal spanners in different sizes, and the combined internal hexagonal spanner device covers various normal specifications of the internal hexagonal spanners, so that the combined design is achieved.

Description

technical field [0001] The invention relates to the technical field of combined wrenches, in particular to a combined hexagonal wrench device. Background technique [0002] Hexagon socket head screws have the characteristics of high thread strength, easy fastening and disassembly, and not easy to slip angle, so they are widely used in various mechanical structures. [0003] The fastening and dismounting of hexagonal screws requires the use of hexagonal wrench. The existing hexagonal wrench is a single hexagonal prism. The widely used hexagonal wrench is divided into two types: L type and T type. The contact area between the wrench and the human hand is small when the wrench is in use, and the pressure of the wrench on the human hand is relatively large, which limits the tightening force of the user on the wrench to a certain extent; There are different specifications of hexagon socket screws, resulting in poor flexibility in use. Contents of the invention [0004] In ord...
