The specific embodiment

Below in conjunction with accompanying drawing spanner described in the utility model is elaborated.

As shown in Figure 1, Fig. 1 is the structural representation of described spanner, and described spanner specifically comprises: two ends head 1,2 and mid-handle 3, described handle are provided with at least one hole 4.

Wherein, the structure of described head 1 as shown in Figure 2, described head 1 is provided with by two relative clamping parts 6, an opening is formed in described clamping part and bottom surface 5, two medial surfaces 7 of described clamping part are parallel to each other; Described bottom surface 5 is for being connected with two medial surfaces respectively, and described bottom surface 5 is in the inclined-plane of set angle α for the outer surface 8 with clamping part.

The structure of described bottom surface 5 as shown in Figure 3, Fig. 3 is the generalized section of spanner described in the utility model, the span of the angle α between described outer surface 8 and the described bottom surface 5 is: 30≤α≤70 degree; In specific implementation process of the present utility model, described angle α is 60 degree.

The structure of described head 2 as shown in Figure 4, described head 2 comprises the opening of being made up of two relative clamping parts 9,10 and bottom surface 11, the medial surface 12 of described clamping part 9 is a trapezoidal faces; Described bottom surface 11 is arc-shaped surface or plane.

Wherein, described medial surface 12 is made up of plane 13, plane 14 and inclined-plane 15, and described plane 13 is parallel with the medial surface of plane 14 difference clamping parts 10, and described inclined-plane 15 is connected between plane 13 and the plane 14.

For example the duty of spanner described in the utility model is described in detail below.

As shown in Figure 5, the utility model is the same with special spanner in the past with spanner commonly used, can be orthohexagonal nut outside the levels operation.

As shown in Figure 6, the bottom surface 5 that spanner described in the utility model can utilize outside the cylinder table face of 7/16DIN connector end and the facet between the hexagon table top is placed spanner, on described bottom surface 5 flat cards and the described facet, like this, the cylinder table top just can be dodged in the bottom surface 5 of spanner design, spanner has obtained the stressed position of a balance, can operate with the less radius of gyration, therefore the utility model goes for the situation of connector indent in equipment, as shown in Figure 7, Figure 7 shows that spanner described in the utility model is applied in the schematic diagram of connector indent in equipment.

As shown in Figure 8, if the connector nut top of operation is plane, the utility model can also be directly with bottom surface 5 flat cards in nut end face, brace arm tilts naturally, can finish the revolution of spanner at small space equally, thereby screw or unscrew operated nut.

The medial surface 12 of the clamping part 9 of the head 2 of spanner described in the utility model is a cascaded surface, is 18～21 N type radio frequency connector so connect the garden diameter in can operating, and is concrete as Fig. 9 and shown in Figure 10.Fig. 9 utilizes plane 13 in the medial surface 12 to screw or unscrew the user mode schematic diagram of hex nut, and Figure 10 utilizes another plane 14 in the medial surface 12 to screw or unscrew the user mode schematic diagram of hex nut.

In addition, as shown in Figure 1, at least one hole 4 can be set on the pinch bar, be used for the convenient described spanner that hangs, the shape in hole can have any shape, such as, circle, regular hexagon etc., if be designed to regular hexagon, described spanner can also be used in the bigger space, with described orthohexagonal borehole jack on the regular hexagon nut of corresponding size, by the head of rotary spanner, play the effect that screws or unscrew nut, like this, can play multiduty effect, like this, a spanner can be applied to polytype nut, reaches the purpose that is convenient for carrying.

In sum, the utility model provides a kind of multiduty spanner, and described spanner one end can be finished the operation of the 7/16DIN type connector of various locus, and the other end can be finished the operation of the N Connector of multiple appearance and size.

The utility model sets about from the upper surface of radio frequency connector screw thread considering, introducing can be rotated the mode of operation of radio frequency connector from multi-angle oblique, thereby can be implemented in the interior locking of a small space that caves in and unclamp radio frequency connector, save space and stressed good, be convenient to operation.Having solved the radio frequency connector that is contained at present in the interior concave space can't use Wrench to screw and unscrew the difficult problem of operation.Ladder wrench faces in the utility model can be operated the N Connector of multiple appearance and size.

Here, to be example with 7/16DIN class connector and N Connector only be illustrated the application of spanner described in the utility model present embodiment, but those skilled in the art will be appreciated that, spanner described in the utility model is equally applicable in other small space, tighten and unclamp similar regular hexagon nut, the angle of inclination of described spanner bottom surface 5 can customize according to actual conditions, the size dimension of described spanner and thickness also can customize according to actual conditions, just repeat no more herein.

The above; it only is the preferable specific embodiment of utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, the protection domain of utility model should be as the criterion with the protection domain of claims.
