Abstract

The utility model discloses a wrench with a handle capable of rotating upwards and downwards. The utility model aims to provide a wrench with a handle capable of rotating upwards and downwards, which is suitable to be used for screwing nuts or bolt heads arranged in counter-bored holes or pits. The wrench comprises a wrench head, a handle and a rotating shaft, wherein the wrench head and the handle are connected by the rotating shaft, and the rotating shaft is parallel to a rotating plane of the wrench head. The wrench disclosed by the utility model has the beneficial effects that: the wrench can screw nuts or bolt heads arranged in counter-bored holes or pits; and the wrench is simple in structure, convenient to manufacture, and easy to operate.

Description

The spanner that a kind of handle can rotate up and down
Technical field
The utility model relates to a kind of hardware & tools, refers in particular to the spanner that a kind of handle can rotate up and down.
Background technology
Usually, spanner is the hand tools that utilizes lever principle to tight a bolt.Existing this type of spanner since driving end and handle in same plane; Therefore, when nut or bolt head were positioned at counterbore or recess, driving end certain angle that must tilt could be used; Thereby cause the contact-making surface of bayonet socket and nut or bolt head of driving end too small; Spanner is skidded easily, and when counterbore or depression were dark, then existing spanner can't use at all.
Chinese patent Granted publication number: CN 1370658A, on 09 25th, 2002 Granted publication day, a kind of monkey wrench is disclosed, include a body, have a fixed jaw and leader.Weak point of the present invention is, when nut or bolt head were positioned at counterbore or recess, this spanner still can't use.
The utility model content
The utility model is to be difficult to turn and to be positioned at counterbore or the nut of depression or the deficiency of bolt head in order to overcome spanner in the prior art, provides a kind of being applicable to turn the spanner that the handle that is positioned at counterbore or nut that caves in or bolt head can rotate up and down.
To achieve these goals, the utility model adopts following technical scheme:
The spanner that a kind of handle can rotate up and down comprises driving end, handle and turning cylinder, is connected through turning cylinder between described driving end and the handle, and described turning cylinder is parallel with the rotational plane of driving end.
Be connected through turning cylinder between described driving end and the handle; Described turning cylinder is parallel with the rotational plane of driving end, then in the time need turning nut or the bolt head that is positioned at counterbore or depression, and rotatable handles; Thereby make handle head continue to be positioned at counterbore or depression; Keep the original contact-making surface of bayonet socket, guarantee the normal use of spanner, and simple operation.
As preferably, described spanner is fork spanner or monkey wrench.
The beneficial effect of the utility model is: can turn the nut or the bolt head that are positioned at counterbore or depression, and simple in structure, convenient manufacturing, simple operation.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
Among the figure: 1. driving end, 2. handle, 3. turning cylinder.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further description.
In the described embodiment of Fig. 1, the spanner that a kind of handle can rotate up and down comprises driving end 1, handle 2 and turning cylinder 3, is connected through turning cylinder 3 between described driving end 1 and the handle 2, and described turning cylinder 3 is parallel with the rotational plane of driving end 1.Described spanner is fork spanner or monkey wrench.
When running into bolt head or nut and be positioned at counterbore or recessed position; Can handle 2 be rotated up certain angle; Driving end 1 is placed in counterbore or the depression, makes the bayonet socket of driving end 1 block bolt head or nut, guarantee the contact area of driving end 1 bayonet socket and bolt head or nut; Avoid handle 2 and the mutual interference that makes counterbore or depression upper edge, thereby make spanner successfully swivel bolt head or nut.
