DETAILED DESCRIPTION OF THE INVENTION
In order that those skilled in the art can further understand the present invention, a description will be described in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.
With reference to FIG. 3, the present invention is illustrated. The present invention has the following elements.
A display panel 20 has a plurality of unidirectional ratchet holes 21. A lower side of the display panel 20 has a cambered slot 22.
A polygonal cylinder 40 is includes. The shape of each ratchet hole 21 is corresponding to that of a protruding post 41 at a front end of a polygonal cylinder 40 so as to receive the cylinder 40. In this embodiment, one end of the cylinder 40 is a rectangular protruding post 41 and another end thereof is a hexagonal section 42 for receiving the clamping portions 11, 12 of an adjustable spanner 1. The cover 43 is connected to the hexagonal post 42 for retaining the adjustable spanner 10. A surface of the protruding post 41 can be coated with combining agent for fixing the polygonal cylinder 40 to the ratchet hole 21.
A clip 30 has a U shape. A front end of each of two sides of the clip 30 is a round post 32.
A strip buckle 31 is included. Each of two ends of the strip buckle 31 is a respective recess 311. The round post 32 passes through the cambered slot 22 and then is buckled into a respective one of the recess 311. By high frequency technology, the clip 30 is firmly secured to the strip buckle 31. The clip 30 of U shape can be bent slightly to has an arc like that of the cambered slot 22 so that the clip 30 slides along the cambered slot 22.
With reference to FIG. 4, a schematic view about the assembly of the present invention is illustrated. It is illustrated that the display panel 20 can be formed with a suspending hole 23 for suspending the display panel 20.
With reference to FIG. 5, a schematic view showing the operation of the adjustable spanner 10, wherein the upper and lower clamping portions 11, 12 of the adjustable spanner 10 clamp the hexagonal post 42. The clip 30 clamps the adjustable spanner 10 at a neck portion 13 of the adjustable spanner 10. When a force is applied to the adjustable spanner 10 along a direction G, see FIG. 5, the adjustable spanner 10 will move from the position P1 to the position P2 so as to tight the hexagonal post 42.
With reference to FIGS. 4 and 6, since the polygonal cylinder 40 embedded into the unidirectional ratchet hole has an irreversible unidirectional clockwise rotating direction D1. A pivotal unit 14 is connected between the upper clamping portion 11 and the lower clamping portion 12. When a force is applied to the adjustable spanner 10 along a direction G2, see FIG. 6 (that is, the clip 30 moves from the first position P1 to the second position P2). The upper clamping portion 11 and the lower clamping portion 12 will expand to have a gap 15 so that the hexagonal post 42 can not be clamped. Namely, when the polygonal cylinder 40 on the display panel 20 is tightened or released, it is unnecessary to take the adjustable spanner 10 away from the display panel 20. It is only necessary to move the adjustable spanner 10 reciprocally, the hexagonal post 42 can be tightened or released. The cover 43 has a transparent material. The consumer can view the action of the display panel 20.
Referring to FIG. 7A, it is illustrated that the surface of the display panel 20 of the present invention can be adhered with a description used paper 50 for describing the function of the display panel 20. The shape and size of the paper 50 is matched to the space of the display panel 20. A hole 51 is formed on the paper 51. The size of the hole 51 is slightly larger than the diameter of the ratchet hole 21. A lower section of the paper 51 is formed with a cambered slit 501. The size of the cambered slit 501 is larger than the cambered slot 22 of the display panel 20. Each of two lateral sides of the paper 50 has a respective triangular label 52. Two lateral sides of the ratchet hole 21 are punched with respective triangular noses 24 so that the paper 50 can be accurately adhered to the display panel 20.
With reference to FIG. 8, a schematic view showing the adhesion of the paper 50. When adhering the paper 50, the triangular labels 52 of the paper 50 are aligned to the triangular noses 24 of the display panel 20. Then a protection film 53 at one side of the paper 50 is torn away, see FIG. 9. The protection firm 54 at another side of the paper 50 is also torn away, see FIG. 10.
Thereby the hole 51 of the paper 50 can complete align to the ratchet hole 21 of the display panel 20 with shiftness and the operation can be made easily.
The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
