Detailed description of the invention

For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with specific embodiment, and Referring to the drawings, the utility model is further described.

As it is shown in figure 1, the present invention provides an embodiment of a kind of spanner:

A kind of spanner, including two brace arms 2, the head end of two brace arms 2 is hinged, and hinged place is provided with bulge-structure 1, often Be provided with being respectively symmetrically on individual brace arm 2 one with the equidirectional extension of described bulge-structure 1 pull ability to speak 3, pull ability to speak 3 end inside Lateral buckling, makes to pull ability to speak 3 L-shaped.When using this spanner, utilize regulations and parameters principle, with bulge-structure 1 as fulcrum, utilize and pull ability to speak 3 Grab the lower end closing the second connector that scaffold board for building card is buckled, and the L-shaped pulling ability to speak 3 conveniently blocks the lower end of the second connector Face, thus utilize lever principle, scaffold board for building buckle is fallen from scaffold board for building.

As shown in Figure 2,3, 4, the present invention provides another embodiment of a kind of spanner:

A kind of spanner, including two brace arms 2, the head end of two brace arms 2 is hinged, and hinged place is provided with bulge-structure 1, often Be provided with being respectively symmetrically on individual brace arm one with the equidirectional extension of described bulge-structure pull ability to speak 3, pull ability to speak 3 end to inner side Bending, makes to pull ability to speak 3 L-shaped.When brace arm 2 is held with a firm grip, pull ability to speak 3 end and just face occlusion, and angle parallel；Make Pull the both sides that ability to speak 3 is engaged in buckle the second connector 7 respectively with during this spanner two, from the lower surface card of the second connector 7 Live the both sides of buckle the second connector 7.

Described hinged place is provided with torsion spring 5, and the two ends of torsion spring 5 are positioned inside brace arm 2, and torsion spring 5 has two effects, one Being conveniently to use, after spanner of holding with a firm grip every time, the inner side of brace arm 2 is withstood at torsion spring 5 two ends, and when pine power, torsion spring 5 makes spanner Arm 2 automatically restores to the state do not held with a firm grip, thus facilitates the use of spanner next time.

Having fixed groove inside described brace arm 2, the both ends of described torsion spring 5 are respectively placed in the described of each brace arm 2 In groove, when hold with a firm grip spanner when, torsion spring 5 is compressed by brace arm, and the inner side of brace arm is withstood at the two ends of torsion spring 5, now exists and turns round The problem slided in spring 5 two ends, the groove that brace arm 2 is arranged can be prevented effectively from torsion spring 5 two ends when firmly holding spanner with a firm grip and slide.

Described brace arm 2 is aduncate arc along brace arm prolonging direction, and when brace arm 2 is held with a firm grip, this arc can So that the ability to speak 3 of pulling being positioned on brace arm 2 is parallel to each other, thus the angle with stress at more suitable buckle the second connector 7 will Buckle takes off.

The end of each described brace arm 2 is provided with along the handle 4 in outside bending for the brace arm prolonging direction, this arc with pull The bending direction of arm 2 is contrary, uses regulations and parameters principle, thus more convenient holds and firmly hold with a firm grip brace arm 2.

Described bulge-structure is cylinder or prism.

The described cross section pulling ability to speak is sheet.

A height of 5mm～the 50mm of described bulge-structure 1；The described a length of 5mm～30mm pulling ability to speak 3, kink is a length of 3mm～20mm.

The described length pulling ability to speak 3 is equal with the height of described bulge-structure 1.

Shown in Figure 5, it is the scaffold board for building buckle structure of spanner application in above-described embodiment, including use quality of rubber materials The first connector 6 made and the second connector 7, the cross section of the first connector 6 is U-shaped, and the cross section of the second connector 7 is I shape, Connect with bottom the U-shaped of the first connector 6 inside second connector 7, and the first connector 6 is perpendicular to the second connector 7, second Pasting reflecting strips 8 outside connector 7, the depth of section of the second connector 7 is more than the depth of section of the first connector 6, and first Connector 6 is arranged on the middle part inside the second connector 7；It is equipped with anti-skid structure on first connector 6 both sides lateral surface, anti-skidding Structure extends to inside the second connector 7 two ends groove, and anti-skid structure is projecting on the first connector 6 both sides lateral surface Anti-slip veins 9；When scaffold board for building buckle is installed, installation notch from color steel for first connector 6 passes, and the first connector U-type groove mouth on 6 is buckled on steelframe crossbeam, by anti-skid structure on the first connector 6 both sides lateral surface by the second connector 7 It is squeezed on color steel, reach color steel and be fastenedly connected with steelframe crossbeam.

The method using this spanner is: by the both sides of second connector pulling ability to speak alignment scaffold board for building buckle of spanner, Holding with a firm grip spanner handle, L-shaped is pulled ability to speak and is stuck in bottom the second connector and U-lag, utilizes regulations and parameters principle, with bulge-structure as fulcrum, Pull ability to speak and firmly grasp scaffold board for building buckle, firmly prize scaffold board for building buckle towards the direction away from steel plate, thus easily will building Frame plate buckle is dragged from steel plate.

It should be noted that the statement of all uses " first " and " second " is for district in the utility model embodiment The entity of point two same names non-equal or the parameter of non-equal, it is seen that " first " " second " only for the convenience of statement, Should not be construed as the restriction to the utility model embodiment, this is no longer illustrated by subsequent embodiment one by one.

Those of ordinary skill in the field are it is understood that the discussion of any of the above embodiment is exemplary only, not It is intended to imply that the scope of the present disclosure (including claim) is limited to these examples；Under thinking of the present utility model, above reality Execute and also can be combined between the technical characteristic in example or different embodiment, and exist of the present utility model as above Other changes of the many of different aspect, for their not offers in details simple and clear.Therefore, all in spirit of the present utility model Within principle, any omission of being made, modification, equivalent, improvement etc., should be included in protection domain of the present utility model Within.
