It is slidably matched.
Preferably, the handle is thread barrel, with being connected inside thread barrel at the top of elastic tweezer bar；In in adjustment barrel on handle
Side is additionally provided with the adjusting nut for crimping adjustment barrel, and adjusting nut coordinates with thread barrel screw thread.
Preferably, the adjusting nut is connected with adjustment barrel by bearing, and the inner ring of bearing is nested in adjustment barrel, bearing
Outer ring it is nested on adjusting nut, and the inner ring of bearing and outer ring be interference fitted with adjustment barrel and adjusting nut respectively.
Preferably, the handle top is provided with cross bar.
Preferably, the handle base outer wall is provided with defining flange, and the external diameter of defining flange is more than the external diameter of adjustment barrel.
Preferably, under the adjustment barrel bottom and defining flange top contact state, two elastic ends of the tweezer bar away from handle
Portion mutually pushes against contact.
Preferably, the push rod bottom is provided with ball, and the part sphere of ball is embedded in the chute conduit of elastic tweezer bar.
The use process of the present invention is as follows：
The present invention can be used according to the application method of conventional tweezers, and small article is clamped using two elastic tweezer bars, when
When needing to keep the relative position of two bullet tweezer bars to keep the lasting clamp position to article, tune is driven by rotating adjusting nut
Section cylinder rises or falls, and then adjusts two push rods to the top pressure position of two elastic tweezer bars, finally realizes the relative of two elastic tweezer bars
The regulation of position, while adjusting nut position in the case where being acted on without external force is fixed, and then keep adjustment barrel, push rod and two elastic tweezer bars
Present position it is stable, realize the effect persistently clamped.
Meanwhile the present invention can also realize the folding distance of two elastic tweezer bars of control, root by the change of push rod position
Suitable folding distance is selected according to the size of gripped object, by the stroke of compression elasticity tweezer bar when can effectively shorten clamping, and then
The efficiency and effect of clamping are improved, when particularly running into less gripped object, if the distance of two elastic tweezer bars is excessive,
Pressing stroke can also increase during clamping, often reduce the efficiency and effect of clamping.
The setting of bearing, it ensure that adjustment barrel will not rotate with the rotation of adjusting nut；Mandrel ends pass through ball
It is connected with the chute of elastic tweezer bar, and the bead of ball at least half volume is located in chute, greatly reduces push rod along chute
Frictional force when mobile, regulation process more convenient and efficient.
The setting of defining flange, the stroke of the stroke of adjustment barrel and two elastic tweezer bars can be defined, prevent two
Elastic tweezer bar excessively causes the damage of elastic tweezer bar to pressure.
The present invention compared with prior art, has the following advantages that：Present invention tweezers simple in construction, ingenious in design, described
Clamp position can also be kept after finger pressing is departed from, substantially increase electronic product maintenance or the use of other application
Convenience.

Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
As Figure 1-3, a kind of tweezers of sustainable clamping, including main body 1, the main body 1 include handle 2
With two curved elastic tweezer bars 11, two elastic tweezer bars 11 are relative in intrados and are symmetrical with the distribution of the axis of handle 2, the handle
2 be thread barrel, and the elastic top of tweezer bar 11 is fixedly connected with the bottom interior wall of handle 2；Adjustment barrel 4, adjustment barrel are arranged with handle 2
4 both sides are respectively equipped with push rod 41, and the bottom of push rod 41 is provided with ball, and the part sphere of ball is embedded in the chute of elastic tweezer bar 11
In 111 conduits；
Be additionally provided with adjusting nut 3 on handle 2 above adjustment barrel 4, adjusting nut 3 coordinates with thread barrel screw thread, adjusting nut 3 with
