Abstract
The utility model discloses a wrench, comprising a wrench body which is bended into an L shape. The transverse planesat both ends of the wrench body are right pentagon planes. Counter bores are not prone to be damaged by the wrench or slide away when the wrench is operated thereon.
Description
Technical field
The utility model relates to a kind of hand-operated tools, specifically is a kind of spanner.
Background technology
The structure of screw generally comprises spiral shell head and threaded screw rod, the screw that generally uses generally is the standard component of securing member at present, in some common equipment field, the screw of fastening apparatus is not wished after fastening released, as: electric power facility, bridge, high frame iron tower, recreation facility, highway garbage can, the underground well lid of road administration, cable machinery control cabinet etc., in case unclamped the screw of connection easily by the people, will produce potential safety hazard, bring unnecessary trouble for people's live and work.Therefore, a lot of securing member manufacturer production some screws that must use special spanner just can unclamp, as hexagon socket head cap screw etc., must use supporting inner hexagon spanner screw could be unclamped.Though this hexagon socket head cap screw plays the effect of better protect common equipment; but in actual applications; because the cross section of the interior hexagonal counterbore of hexagon socket head cap screw is generally regular hexagon; regular hexagonal section is near circular cross-section; when the interior hexagonal counterbore of inner hexagon spanner insertion screw carries out tighten the screws; excessive or overexert if exert oneself; six inclines of this inner hexagon spanner will damaged screws in six medial surfaces of hexagonal counterbore; cause the interior hexagonal counterbore of the screw circular counterbore that weares and teares; thereby inner hexagon spanner is skidded, and screw just is difficult to tighten like this, and the staff has to change screw; installation cost is increased, and influence erection schedule.
The utility model content
The technical problems to be solved in the utility model is to overcome the defective of above prior art, the spanner that a kind of screw terminal counterbore not easy to wear is provided and is difficult for skidding.
Technical solution of the present utility model is that a kind of spanner with following structure is provided: it comprises and bends to L shaped wrench body that the two ends cross section of described wrench body is the regular pentagon cross section.
After adopting above structure, the utility model spanner compared with prior art, have the following advantages: because the two ends cross section of this spanner is the regular pentagon cross section, so this spanner is when tightening or unclamp inner pentagonal screw, five medial surface contacts area of five lateral surfaces of this spanner and interior five jiaos of counterbores of inner pentagonal screw are big, thus the counterbore that spanner screw terminal not easy to wear and spanner are matched, when tightening or unclamp screw, this spanner can not skid, and has therefore improved the erection schedule of screw.
As a kind of improvement, described wrench body is the crooked 90 degree molding structures of positive pentagonal prism.When making this spanner, only need like this, on lathe, bend into 90 degree and get final product, so production cost is low the pentagonal prism blank that is equipped with.
Description of drawings
Fig. 1 is the structural representation of the utility model spanner.
Fig. 2 is the side structure schematic diagram of the utility model spanner.
Fig. 3 is the A-A sectional structure schematic diagram of the utility model in Fig. 1.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As Fig. 1, Fig. 2 and shown in Figure 3.
A kind of spanner of the utility model, it comprises and bends to L shaped wrench body that the two ends cross section of described wrench body is the regular pentagon cross section.
Described wrench body is the crooked 90 degree molding structures of positive pentagonal prism.
Claims (2)
1. spanner, it comprises and bends to L shaped wrench body that it is characterized in that: the two ends cross section of described wrench body is the regular pentagon cross section.
2. spanner according to claim 1 is characterized in that: described wrench body is the crooked 90 degree molding structures of positive pentagonal prism.
