Abstract
The application relates to a kind of spanner with barrier structure, including spanner handle, and it is arranged on the driving end of spanner handle end, described driving end has the recess of a clamping screw cap, it is capped with baffle plate at back segment upper port in described recess, recess is divided into the most uncovered anterior leading portion nut space, and semi-enclosed back segment nut space, rear portion by baffle plate.Owing to implementing technique scheme, the application simple in construction, applied widely, can prevent spanner from departing from nut during turning, improve work efficiency.
Description
Technical field
The application relates to a kind of spanner, particularly relates to a kind of spanner with barrier structure having and preventing spanner from departing from nut during turning.
Background technology
Spanner is used to loosen or during terminal operation nut is carried out; owing to spanner force direction can not keep the moment vertical with nut axis; spanner is easily moved along nut axis direction; in whole operation process; spanner is often occurred to depart from the phenomenon of nut; thus needing frequently to adjust spanner so that spanner and nut are positioned at best combination position, and then affect work efficiency.
Summary of the invention
The purpose of the application is to propose a kind of spanner with barrier structure preventing spanner from departing from nut during turning.
The purpose of the application is achieved in that the spanner with barrier structure includes spanner handle, and it is arranged on the driving end of spanner handle end, described driving end has the recess of a clamping screw cap, it is capped with baffle plate at back segment upper port in described recess, recess is divided into the most uncovered anterior leading portion nut space, and semi-enclosed back segment nut space, rear portion by baffle plate.
Owing to implementing technique scheme, the application simple in construction, applied widely, can prevent spanner from departing from nut during turning, improve work efficiency.
Accompanying drawing illustrates: concrete structure of the present utility model is given by following drawings and Examples:
Fig. 1 is the cross-sectional view of the spanner with barrier structure；
Fig. 2 is the spanner structure schematic diagram with barrier structure；
Fig. 3 is the baffle arrangement schematic diagram of outer recessed convex；
Fig. 4 is the baffle arrangement schematic diagram of evagination indent.
Legend: 1, driving end, 2, baffle plate, 3, spanner handle, 4, back segment nut space, 5, leading portion nut space, 21, horn mouth, 22, semi-circular indentation, 23, first surface, the 24, second curved surface.
Detailed description of the invention:
The application is not limited by following embodiment, can determine specific embodiment according to the technical scheme of the application and practical situation.
Embodiment: as shown in Figure 1, 2, spanner with barrier structure includes spanner handle 3, and it is arranged on the driving end 1 of spanner handle 3 end, described driving end 1 has the recess of a clamping screw cap, baffle plate 2 it is capped with at back segment upper port in described recess, recess is divided into the most uncovered anterior leading portion nut space 5, and semi-enclosed back segment nut space, rear portion 4 by baffle plate 2.
Described baffle plate 2 center offers baffle plate recess, and described baffle plate recess is in order to card connecting bolt, and it has is located at inner most semi-circular indentation 22, and is arranged on the horn mouth 21 at semi-circular indentation collar extension.
Along being respectively provided with first surface 23 and the second curved surface 24 from outside to inside in described horn mouth 21 both sides, described first surface 23 and the second curved surface 24 bending direction are contrary.
Described first surface 23 caves in outside baffle plate 2, and described second curved surface 24 caves in inside baffle plate recess.
Described first surface 23 caves in inside baffle plate 2, and described second curved surface 24 caves in outside baffle plate recess.
Described first surface 23 and the second curved surface 24 curvature are less than the curvature of semi-circular indentation 22.
This kind of structure be disposed to when bolt cannot be introduced into semi-circular indentation 22, can be located at first surface 23 or the second curved surface 24 position, to meet the demand of different situations.
The application is in use, when needs turn single bolt or single nut, can be by back segment nut space 4 clamping of single nut with the application, now baffle plate 2 is positioned on the upside of it or downside according to single nut stressing conditions, single bolt enters in baffle plate recess, so during turning, baffle plate 2 can stop spanner upwardly away from.
When if desired turning double nut locking mechanism, owing to double nut thickness is enough, leading portion nut space 5 can be used, so that the application is applicable to various situation.
Above technical characteristic constitutes most preferred embodiment of the present utility model, and it has stronger adaptability and optimal implementation result, can increase and decrease inessential technical characteristic according to actual needs, meet the needs of different situations.
