Abstract
The invention belongs to hardware tool fields, specifically, it is a kind of box spanner, including wrench body, the groove that connection spanner handle is provided at the top of wrench body is set as inverted draw cut, the bottom of wrench body is for loosening or the sets of holes of screwing bolts, the through hole being provided between the inverted draw cut and sets of holes of wrench body through entire wrench body is used to that power-assisted stick is arranged, the box spanner of present disclosure increases the use of power-assisted stick, under the effect of the double leverage of power-assisted stick and spanner handle, so that screwing or loose nut is more laborsaving；Wrench body is used with spanner handle and power-assisted stick and is detachably connected, so that storing and replacing more convenient；The case where intensity of power-assisted stick is less than the intensity of wrench body, avoids power-assisted stick damage wrench body generation.
Description
Technical field
The invention belongs to hardware tool fields, specifically, being a kind of box spanner.
Background technique
Box spanner is commonly referred to as sleeve：It is by multiple sleeves with hexagon ring or 12 corner apertures and equipped with handle, connect
The multiple accessories such as bar composition, especially suitable for twist status it is very narrow or recess very deep bolt or nut.Sleeve has public affairs
Point of system and English system, although sleeve concave shape is the same, outer diameter, length etc. are the shape and size designs for corresponding equipment
, country does not have Uniform provisions, so the design of sleeve is comparatively relatively more flexible, meets public needs.Box spanner one
As collet head all with a set of various specifications and handle of waving, extension bar, universal joint, driver connector, elbow handle etc. be used to
It is inserted in hexagonal (hexagon)nut.The collet head of box spanner is a recessed hexagonal cylinder；Spanner is usually by structural carbon steel or alloy
Structural steel is made, and Wrench head has defined hardness, and intermediate and handle portion then has elasticity.
Box spanner in the prior art can only be screwed or be loosened to nut using handle for user, and effect is past
Past is not fine.
Summary of the invention
In order to solve the above technical problem, the present invention provides a kind of box spanners, and handle not only can be used, and can also borrow
Power-assisted stick screws nut or is loosened under the collective effect of handle and power-assisted stick, more easily quick, improves
Working efficiency.
The specific technical solution that the present invention uses is as follows：
A kind of box spanner, including wrench body, the groove that wrench body top is provided with connection spanner handle are set as inverted draw cut, pull
The bottom of hand ontology is provided between the inverted draw cut and sets of holes of wrench body through whole for loosening or the sets of holes of screwing bolts
The through hole of a wrench body is used to that power-assisted stick is arranged.
Further improvement of the present invention, with the connection of spanner handle using being threadedly coupled, threaded connection can to pull inverted draw cut
Hand ontology and spanner handle are separable, convenient for storage.
Further improvement of the present invention, spanner handle are designed using L shape, and one end of spanner handle is provided with screw thread and inverted draw cut connects
It connects, the other end setting rubber sleeve of spanner handle convenient for grasping, be convenient in wide spatial dimension by the spanner handle of L shape design
It uses.
Further improvement of the present invention, spanner handle use "T"-shaped design, the "T"-shaped bottom of spanner handle be provided with screw thread with
Inverted draw cut connection, convenient for grasping, the spanner handle of "T"-shaped design can make the "T"-shaped transverse ends setting rubber sleeve of spanner handle
The box spanner uses in narrow space.
Further improvement of the present invention, the intensity of power-assisted stick are less than the intensity of sleeve body, and the intensity of power-assisted stick is less than set
The intensity of cylinder ontology, during the work time, when firmly excessive, power-assisted stick is first broken, and can thus be damaged to avoid power-assisted stick
The case where wrench body, occurs, and protects wrench body.
Beneficial effects of the present invention：The box spanner of present disclosure increases the use of power-assisted stick, in power-assisted stick and pulls
Under the double leverage effect of handle, so that screwing or loose nut is more laborsaving；Wrench body is adopted with spanner handle and power-assisted stick
With being detachably connected, so that storing and replacing more convenient；The intensity of power-assisted stick is less than the intensity of wrench body, avoids power-assisted
The case where stick damage wrench body, occurs.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
In figure, 1- wrench body, 2- inverted draw cut, 3- sets of holes, 4- spanner handle, 5- through hole, 6- power-assisted stick.
Specific embodiment
In order to deepen the understanding of the present invention, the present invention is done below in conjunction with drawings and examples and is further retouched in detail
It states, the embodiment is only for explaining the present invention, does not constitute and limits to protection scope of the present invention.
Embodiment：As shown in Figure 1, a kind of box spanner, including wrench body 1, connection is provided at the top of wrench body 1 and is pulled
The groove of handle 4 is set as inverted draw cut 2, and the bottom of wrench body 1 is the wrench body 1 for loosening or the sets of holes 3 of screwing bolts
Inverted draw cut 2 and sets of holes 3 between be provided with through entire wrench body 1 through hole 5 be used to power-assisted stick 6, inverted draw cut 2 and spanner are set
The connection of handle 4 is using being threadedly coupled, and threaded connection can make wrench body 1 and spanner handle 4 separable, convenient for storage.
Generally, spanner handle 4 is designed using L shape, and one end of spanner handle 4 is provided with screw thread and connect with inverted draw cut 2, spanner handle
4 other end setting rubber sleeve is convenient for grasping；In narrow working environment, spanner handle 4 can also use "T"-shaped design,
The "T"-shaped bottom of spanner handle 4 is provided with screw thread and connect with inverted draw cut 2, and the "T"-shaped transverse ends setting rubber sleeve of spanner handle 4 is just
In grasping.
In the present embodiment, the intensity of power-assisted stick 6 is less than the intensity of sleeve body, and the intensity of power-assisted stick 6 is less than sleeve sheet
The intensity of body, during the work time, when firmly excessive, power-assisted stick 6 is first broken, and can thus be damaged and be pulled to avoid power-assisted stick 6
The case where hand ontology 1, occurs, and protects wrench body 1.
Basic principles and main features and advantage of the invention have been shown and described above.The technical staff of the industry should
Understand, the present invention is not limited to the above embodiments, and the above embodiments and description only describe originals of the invention
Reason, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes and improvements
It all fall within the protetion scope of the claimed invention.The claimed scope of the invention is by appended claims and its equivalent circle
It is fixed.
