Description
[ technical field ] A method for producing a semiconductor device
The utility model relates to a hardware and tools technical field, in particular to three pass spanners.
[ background of the invention ]
The wrench is a common mounting and dismounting tool, and is a manual tool for screwing bolts, screws, nuts and other screw threads to tightly hold open or trepanning fasteners of the bolts or nuts by utilizing the lever principle.
In the prior art, the spanner usually has the opening or trepanning of centre gripping bolt or nut at the one end or the both ends system of stalk portion, and external force is applyed at the stalk portion along the screw thread direction of rotation and is twisted bolt or nut during the use, however the operator is mostly one-hand operation like this, and the strength of use is limited, and sometimes bolt or nut are because reasons such as rust, and the strength of light relying on one hand is difficult to twist and change, and the use both hands go on by force, can lead to the health to lose balance when exerting oneself, have certain danger.
[ Utility model ] content
An object of the utility model is to provide a three pass spanner to it is limited to overcome the single hand operation spanner strength in the prior art, and both hands are volatile to go balanced not enough.
In order to achieve the above object, the utility model provides a following technical scheme:
the application discloses three pass spanners, including first spanner head, second spanner head, middle part spanner head and connection handle, the both sides of middle part spanner head are equipped with connection handle, one of them the other end of connecting handle is equipped with first spanner head, another the other end of connecting handle is equipped with second spanner head, the connection handle of middle part spanner head both sides is located same straight line.
Preferably, the first wrench head and the second wrench head are open-type wrench heads, the middle wrench head is a sleeve-type wrench head, and a sleeve hole is formed in the middle of the middle wrench head.
Preferably, the sleeve hole is of a regular dodecagonal structure.
Preferably, the connecting handles on the two sides of the middle wrench head are straight rods, and the middle wrench head, the first wrench head and the second wrench head are located on the same horizontal plane.
Preferably, the connecting handles on two sides of the middle wrench head are bent rods, the first wrench head and the second wrench head are located on the same horizontal plane, and the middle wrench head is higher than the first wrench head.
Preferably, the middle part of the connecting handle is provided with a rubber sheath.
Preferably, the first wrench head and the second wrench head are different in applicable model.
The utility model has the advantages that: compared with the prior art, the three-hole type wrench provided by the utility model has reasonable structure, firstly, the middle wrench head is designed, when the force of one hand can not be used for twisting, the middle wrench head can be sleeved on the bolt or the nut, and the two hands respectively grab the connecting handles at the two sides to apply force for twisting, thereby twisting the bolt or the nut; secondly, the middle wrench head, the first wrench head and the second wrench head are in various forms according to the position relationship, and can be selected according to actual requirements; and thirdly, the design of the first wrench head and the second wrench head which are connected with the two ends of the handle ensures the basic functions of the common wrench and the common wrench.
The features and advantages of the present invention will be described in detail by embodiments with reference to the accompanying drawings.

Fig. 1 is a schematic top view of a three-hole wrench according to an embodiment of the present invention;
FIG. 2 is a schematic side view of a three-hole wrench according to an embodiment of the present invention;
fig. 3 is a schematic side view of a second embodiment of the present invention.
In the figure: 1-a first wrench head, 2-a second wrench head, 3-a middle wrench head, 31-a sleeve hole, 4-a connecting handle and 5-a rubber sheath.
[ detailed description ] embodiments
In order to make the objects, technical solutions and advantages of the present invention more clear, the present invention is further described in detail through the accompanying drawings and embodiments. It should be understood, however, that the description herein of specific embodiments is only intended to illustrate the invention and not to limit the scope of the invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
The first embodiment is as follows:
referring to fig. 1 and 2, an embodiment of the present invention provides a three-hole wrench, which is characterized in that: including first spanner head 1, second spanner head 2, middle part spanner head 3 and connection handle 4, the both sides of middle part spanner head 3 are equipped with connection handle 4, one of them the other end of connecting handle 4 is equipped with first spanner head 1, another the other end of connecting handle 4 is equipped with second spanner head 2, the connection handle 4 of 3 both sides of middle part spanner head is located same straight line.
The connecting handles 4 on two sides of the middle wrench head 3 are straight rods, and the middle wrench head 3, the first wrench head 1 and the second wrench head 2 are positioned on the same horizontal plane. The middle part of the connecting handle 4 is provided with a rubber sheath 5. The applicable models of the first wrench head 1 and the second wrench head 2 are different.
Example two:
