Abstract

The invention discloses a clamp. The clamp comprises two clamp arms, wherein the two clamp arms are hinged through a hinge shaft, and a spring is arranged between the two clamp arms. An adjustment piece which can move up and down and located between the two clamp arms is movably arranged on the hinge shaft. Two oblique edges are arranged on the upper portion of the adjustment piece, and the ends, located above the hinge shaft, of the two clamp arms are correspondingly matched with the two oblique edges on the adjustment piece. According to the clamp, the distance between the two clamp arms can be adjusted through the adjustment piece, fatigue can be relieved after the clamp is used for a long time, and the clamp is suitable for people groups at various ages and with palms of different sizes; and the clamp is convenient to use and good in adaptability.

Description

A kind of fixture

Technical field

The invention belongs to hand tools, and in particular to a kind of fixture.

Technical background

Fixture is a kind of conventional hand tools, can both replace hand to press from both sides food, meets hygienic requirements, and hand can be avoided again Contact harmful substance, widely uses in daily life, industrial production, research and teaching.Existing fixture be divided into plain clamp and Spring chuck, two jig arm of plain clamp are freely hinged, and the folding of jig arm is complete with finger control, using there is certain difficulty Degree；And two jig arm of spring chuck have elasticity, only needing hand to pinch pressure can clamp article, loosen jig arm i.e. under elastic reaction Automatically open, using more convenient, but this spring chuck is disadvantageous in that the amplitude of opening of jig arm is fixed, it is impossible to adjust Section, for clamp different size of item holder hand gripping amplitude, for a long time using easy fatigue, and be not suitable for Various age hand sizes different crowds use, and adaptability is restricted.

The content of the invention

Amplitude, fixture easy to use are opened it is an object of the invention to provide a kind of adjustable jig arm.

Realize that the technical scheme that the object of the invention is used is as follows：

The fixture that the present invention is provided, including be hinged by hinge and between be provided with two jig arm of spring, it is living on the hinge Dynamic to be provided with one and move up and down and the adjustment sheet between two jig arm, the top of the adjustment sheet is provided with two hypotenuses, described Two jig arm be located at hinge above end respectively with adjustment sheet on two hypotenuse corresponding matchings.

The hypotenuse of the adjustment sheet is provided with the seam coordinated with the jig arm end.

The hypotenuse of the adjustment sheet is provided with bayonet socket, bayonet socket is provided with the jig arm end and is engaged with bayonet socket Bending.

The jig arm is divided into the fixed part and movable part being hinged on the hinge, and the movable part is using removable Structure is unloaded to be flexibly connected with the fixed part.

The end of a jig arm in the jig arm is provided with fork or spoon or knife.

Described two jig arm are that, used as the clamping bar of chopsticks, or the other end of two jig arm is provided with clamping plate.

Beneficial effect

The present invention can adjust the size of aperture between two jig arm by adjustment sheet, for a long time using can lessen fatigue, Er Qieshi Close the different crowd of various age hand sizes to use, its is easy to use, and adaptability is preferable.

Technical scheme is further illustrated below in conjunction with the accompanying drawings.

Specific embodiment

Embodiment 1

As shown in Figure 1 and Figure 2, the fixture that the present invention is provided, including two jig arm 1, the top of jig arm 1 is bent into U-lag for sheet material Connecting portion 101, wherein connecting portion for jig arm 1 101 is embedded in the connecting portion 101 of another jig arm 1 and is cut with scissors by hinge 3 Connect, torsion spring 4 is arranged with hinge 3, the two ends of torsion spring 4 are supported between two jig arm 1, and one is movably equipped with hinge 3 can be upper and lower Motion and the adjustment sheet 2 between the connecting portion 101 of two jig arm 1, adjustment sheet 2 are provided with long kidney-shaped hole 203 and match somebody with somebody with hinge 3 Close, the top of adjustment sheet 2 is provided with two hypotenuses 202, its top is provided with as the bending 201 of handle, and two jig arm 1 are located on hinge 3 Side end 102 respectively with adjustment sheet 2 on the corresponding matching of two hypotenuse 202, the bottom of jig arm 1 is provided with clamping plate a.

Original state of the invention as shown in Fig. 2 the end 102 of two jig arm 1 is limited positioned at the apical position of adjustment sheet 2, Because the length on the top of adjustment sheet 2 is minimum, spacing also minimum apart from L1 between the end 102 of two jig arm 1, two jig arm 1 are opened Amplitude L2 is maximum, namely clamping plate a to open amplitude maximum, larger article can be clamped.To opening between two jig arm 1 of regulation Open-width degree L2, can with a hand pinch pressure two jig arm 1, the bending 201 that another hand is pinched on adjustment sheet 2 pull up it is a bit of away from From, then jig arm 1 is unclamped, two jig arm 1 are opened in the presence of torsion spring 4, under the diverse location of hypotenuse 202 is spacing on the adjustment sheet 2, So that spacing apart from L1 increasings between the end 102 of two jig arm 1, the amplitude L2 that opens of the jig arm other end reduces, and clamping plate a can only Less article is clamped, as shown in Figure 3；As drawn adjustment sheet 2 further up, the amplitude L2 that opens of two jig arm 1 can be made to enter one Step reduces, and clamping plate a's opens amplitude minimum, it is impossible to clamps less article, but is easy to storage, as shown in Figure 4.

Embodiment 2

See Fig. 5, in the present embodiment, the hypotenuse 202 of the adjustment sheet 2 is provided with the seam coordinated with the jig arm end 102 204, when adjustment sheet 2 is pulled up, the end 102 in two jig arm 1 is stuck on the seam 204 on the hypotenuse 202 of adjustment sheet 2, As shown in fig. 6, this structure is conducive to the positioning of jig arm 1.

Embodiment 3

See Fig. 7, in the present embodiment, the hypotenuse 202 of the adjustment sheet 2 is provided with bayonet socket 205, and the jig arm end 102 is provided with Towards bayonet socket 205 and the bending 103 that is engaged with bayonet socket 205, when adjustment sheet 2 is pulled up, the bending on two jig arm ends 102 103 are stuck in the bayonet socket 205 on the hypotenuse 202 of adjustment sheet 2, as shown in figure 8, this structure is also beneficial to the positioning of jig arm 1.

Embodiment 4

See Fig. 9, in the present embodiment, 1 point of the jig arm is the fixed part 104 and movable part 105 being hinged on the hinge, The movable part 105 is flexibly connected using demountable structure 106 with the fixed part 104, and demountable structure 106 includes spiral shell The connected modes such as line connection, spring connection, grafting.

Embodiment 5

See Figure 10, in the present embodiment, it is that, as the clamping bar b of chopsticks, can make as tableware chopsticks that the bottom of the jig arm 1 is provided with With, amplitude is opened due to can adjust clamping bar b, the people for being adapted to all ages and classes uses.
