Abstract

An improved hand tool with a controllable push handle steering structure is provided with a working part; the working part consists of two jaws which are mutually articulated with each other; each jaw is respectively provided with an articulation end; each articulation end is respectively articulated with a push handle; wherein, one push handle is provided with an arc-shaped sleeve which extends facing to the other push handle; the other push handle corresponding to the sleeve is provided with an arc-shaped rod which is pierced in the sleeve; a recovery component is arranged between the arc-shaped rod and the sleeve to ensure the two push handles to be synchronously articulated; after the two push handles are relatively grasped, by that the recovery component pushes the arc-shaped rod, the two push handles are recovered. The two push handles of the utility model can be synchronously steered and can be automatically recovered.

Description

Improved have the hand-held tool that can control the handle steering structure

Technical field

The utility model relates to a kind of hand-operated tools, and relating in particular to a kind of two handles can turn to synchronously, and can the automatically reset improved hand-held tool that can control the handle steering structure that has.

Background technology

As shown in Figure 6, the pliers that can turn to for existing a kind of handle, it is to be articulated by two

jaws

81,82 to be combined into an operate portions 8, each

jaw

81,82 has a pivot end 811,821 respectively, each pivot end 811,821

handle

91,92 that is pivoted respectively is by controlling two jaws, 81,82 holding workpieces that this two handle 91,92 drives operate portions 8.

As shown in Figure 7, when using pliers in the plane during holding workpiece 7, grip two

handles

91,92 for ease of the user and drive two jaws, 81,82 holding workpieces 7, two

handles

91,92 upwards can be pivoted respectively, make two

handles

91,92 and interplanar form bigger operating space, be beneficial to user's holding operation two

handles

91,92.

But, pivoting two

handles

91,92 o'clock, handle 91,92 pivots with costing thing one by one, the mode that so pivots causes the angle after two handles 91,92 pivot inconsistent easily, i.e. aspect as shown in Figure 7, two handles, 91,92 pivoting angles are inconsistent can to increase that the user grips, the inconvenience during operation.

The utility model content

In order to overcome the above-mentioned shortcoming that pliers that existing handle can turn to exists, the utility model provides a kind of improved hand-held tool that can control the handle steering structure that has, and its two handle can turn to synchronously, and can automatically reset.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of improved hand-held tool that can control the handle steering structure that has, it has an operate portions, and this operate portions is articulated mutually by two jaws to be formed, and each jaw has a pivot end respectively, and each pivot end is pivoted with a handle respectively; It is characterized in that a described wherein handle is provided with the arc shrouds that one day, another handle extended, and another handle is to being provided with a bow that is extended through in this sleeve pipe by sleeve pipe, be provided with a reset assembly between this bow and this sleeve pipe, make this two handle can be by pivot in unison, after this two handle is held relatively and closed, this two handle is resetted by this bow of reset assembly pushing tow.

The aforesaid improved hand-held tool that can control the handle steering structure that has, wherein reset assembly is a back-moving spring, by the elastic force of this back-moving spring and the pushing tow bow resets this two handle.

The aforesaid improved hand-held tool that to control the handle steering structure that has, wherein reset assembly comprises first magnetite that is embedded in this sleeve pipe, with second magnetite that is incorporated into this bow front end, and the one side that first and second magnetite is adjacent is same polarity, by this bow of magnetic force pushing tow that repels each other of first and second magnetite this two handle is resetted.

Two handles of the present utility model can turn to synchronously, and can automatically reset.

The specific embodiment

See also Fig. 1 to Fig. 4, it shown in the figure the selected example structure of the utility model, present embodiment has an operate portions 1, this operate portions 1 is by two

jaws

11,12 articulate composition mutually, this operate portions 1 forms the form of a clamp, each

jaw

11,12 have a pivot end 111 respectively, 121, each pivot end 111,121 are pivoted with a handle 21 respectively, 22, wherein a handle 22 is provided with the sleeve pipe 23 that one day, another handle 21 arcs extended, and 21 pairs of another handles should be provided with a bow 24 that is extended through in this sleeve pipe 23 by sleeve pipe 23, and this

bow

24 and 23 of this sleeve pipes are provided with a reset assembly.This reset assembly is a back-moving spring 25 in the present embodiment, so that this two

handle

21,22 can be by pivot in unison, and is held relatively at this two

handle

21,22 and can this two

handle

21,22 be resetted by this bow 24 of back-moving spring 25 pushing tows after closing.

See also Fig. 3, when the utility model is used in the plane holding workpiece 3, grips two handles 21,22 for ease of the user and drive two jaws, 11,12 holding workpieces 7, two

handles

21,22 upwards can be pivoted.Because 21,22 of the utility model two handles are to wear binding by sleeve pipe 23 and bow 24, therefore, arbitrary handle 21 or the 22 as long as user pivots, another

handle

22 or 21 just can be driven synchronously and be pivoted, and guarantee the angle unanimity that two handles 21,22 are pivoted, be convenient to that the user grips, operation two handles 21,22 drive two jaws, 11,12 clamping work pieces 7.

Moreover, hold in user's application of force and to close two handles at 21,22 o'clock, bow 24 can push the back-moving spring 25 in the sleeve pipe 23, back-moving spring 25 is compressed, thus, as user no longer during the application of force, the elastic force of back-moving spring 25 just can pushing tow bow 24 and this two

handle

21,22 is resetted, to reach automatically reset effect.

In sum, the utility model is by linking with sleeve pipe 23 that wears mutually and bow 24 21,22 of two handles, two

handles

21,22 are reached by pivot in unison to the effect of consistent angle, and be arranged at sleeve pipe 23 and the back-moving spring 25 of bow 24 and can make two

handles

21,22 be reached automatically reset effect after closing by relative holding.

Certainly, still there are many examples in the utility model, therebetween the only variation on the details.See also Fig. 5, be second embodiment of the present utility model, wherein this reset assembly comprises first a magnetite 26A who is embedded among this sleeve pipe 23A, with second a magnetite 26B who is incorporated into this bow 24A front end, the one side that first and second magnetite 26A, 26B are adjacent is same polarity, can this two handle 21A, 22A be resetted by this bow of magnetic force pushing tow 24A that repels each other of first and second magnetite 26A, 26B, so also can reach identical effect with aforementioned first embodiment.
