Abstract
A novel falling prevention socket spanner comprises a cylinder body and a connection handle fixed on one end face of the cylinder body, wherein a nut accommodating chamber is inwards formed in the other end face of the cylinder body; a locking nut hole is formed in one side wall of the nut accommodating chamber in the radial direction; a pressure spring is arranged in the locking nut hole; a locking nut ejecting ball extending into the nut accommodating chamber is arranged at the end part of the pressure spring. According to the utility model, the structure is simple; during the use of the socket spanner, the connection handle is firmly connected with a portable electric pistol drill, a nut is placed inside the nut accommodating chamber and is tightly locked in the nut accommodating chamber under the action of the locking nut ejecting ball, so that the nut is prevented from falling off; when a step bolt, a flat gasket and a spring pad are completely placed, the cylinder comprising the nut is aligned to a bolt, a pistol drill power switch is started, so that the nut can be tightened; through the adoption of the socket spanner, the operation is simple and convenient, the construction efficiency can be greatly improved, the construction period is shortened, and the construction cost is reduced.
Description
Technical field
The utility model belongs to instrument and electric engineering construction technical field of tools, particularly a kind of Novel anti-drop box spanner.
Background technology
In engineering instrument and electric engineering construction, there is a large amount of cable testing bridges to need to install, the connecting portion of every two joint cable testing bridges (h=200mm) all needs 28 half-round head square neck bolt M10*22 to fix, and therefore, has a large amount of bolted work in cable testing bridge installation.Yet, on market, there is no suitable quick erecting tools, can only select opening fork spanner, double offset ring spanner or monkey wrench as erecting tools, because needs are manually progressively fastening, will expend longer activity duration and higher construction cost; In addition, in opening fork spanner, double offset ring spanner or monkey wrench use procedure, easily there is the phenomenon that nut drops, greatly reduce efficiency of construction.
Utility model content
The purpose of this utility model is to provide a kind of simple in structure, easy and simple to handle and Novel anti-drop box spanner that operating speed is fast.
For achieving the above object, the technical solution of the utility model is: a kind of Novel anti-drop box spanner, comprise cylindrical shell and the connection handle that is fixed on cylindrical shell one end face, described cylindrical shell other end inwardly offers nut cavity volume, on nut cavity volume one sidewall, radially offer latch nut hole, in latch nut hole, be provided with stage clip, stage clip end is provided with the locknut decorative pearl on top of an official cap that stretches into nut cavity volume.
The intersect vertical axis of the axis of described latch nut hole and nut cavity volume.
In described cylindrical shell, be provided with the bolt head cavity volume extending internally along nut cavity volume; Bolt head cavity volume cross section is circular, and nut cavity volume cross section is regular hexagon, and bolt head cavity volume and nut cavity volume coaxially arrange.
Described connection handle cross section is equilateral triangle.
Compared with prior art, advantage of the present utility model is:
1, the utility model comprises cylindrical shell and is fixed on the connection handle of cylindrical shell one end face, described cylindrical shell other end inwardly offers nut cavity volume, on nut cavity volume one sidewall, radially offer latch nut hole, be provided with stage clip in latch nut hole, stage clip end is provided with the locknut decorative pearl on top of an official cap that stretches into nut cavity volume, it is simple in structure, during use, connection handle and portable electric power drill are connected firmly, and nut is put in nut cavity volume, under the effect of the locknut decorative pearl on top of an official cap by nut check in nut cavity volume, prevent from that nut from coming off to drop out; After half-round head square neck bolt, flat shim, spring pad are placed, the cylindrical shell that contains nut is aimed to bolt, open power drill power switch, nut can be tightened, use this instrument, easy and simple to handle, can greatly improve efficiency of construction, shorten construction period and reduce construction cost.
2, in cylindrical shell, be provided with the bolt head cavity volume extending internally along nut cavity volume; Bolt head cavity volume cross section is circular, and nut cavity volume cross section is regular hexagon, and bolt head cavity volume and nut cavity volume coaxially arrange, to avoid in fastening process, because bolt is compared with growing the phenomenon that causes that nut exits cylindrical shell and cannot clamp nut.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the right view of Fig. 1.
The specific embodiment
Novel anti-drop box spanner as shown in Figure 1, Figure 2 and Figure 3, the connection handle 2 that it comprises cylindrical shell 1 and is fixed on cylindrical shell 1 right side, the cross section of connection handle 2 is equilateral triangle, is convenient to realize Rapid Combination with portable electric power drill.In cylindrical shell 1 left side, inwardly offer successively nut cavity volume 3 and bolt head cavity volume 4, the cross section of bolt head cavity volume 4 is circular, and the cross section of nut cavity volume 3 is regular hexagon, and bolt head cavity volume 4 coaxially arranges with nut cavity volume 3.On one of them sidewall of nut cavity volume 3, radially offer latch nut hole 6, the intersect vertical axis of the axis of latch nut hole 6 and nut cavity volume 3; In latch nut hole 6, be provided with stage clip 7, stage clip 7 outer ends are provided with the locknut decorative pearl on top of an official cap 5 that stretches into nut cavity volume 3, the locknut decorative pearl on top of an official cap 5 is for interim locking nut, can nut be placed in nut cavity volume 3 like a cork, even if nut cavity volume 3 oral areas are down time, also can effectively prevent that nut wherein from dropping, and is specially adapted to the work high above the ground of instrument electrical engineering.
In the present embodiment, nut cavity volume 3 adapts with the shape and size of hex nut M10; The diameter of bolt head cavity volume 4 is that 14mm, the degree of depth are 12mm, and in bolted process, bolt head can enter this cavity volume smoothly.
When the utility model is used, connection handle 2 is connected firmly with portable electric power drill, nut is put in nut cavity volume 3, under 5 effects of the locknut decorative pearl on top of an official cap by nut check in nut cavity volume 3, prevent from that nut from coming off to drop out; After half-round head square neck bolt, flat shim, spring pad are placed, the cylindrical shell that contains nut 1 is aimed to bolt, open power drill power switch, nut can be tightened, and uses this instrument, can greatly improve efficiency of construction, saves construction cost.
