Embodiment

Below in conjunction with drawings and Examples, the utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain technical essential of the present utility model, protection domain of the present utility model should comprise the full content of claim, but is not limited thereto.

Embodiment 1

Gear type reducing clamping device as Figure 1-3, it comprises with lower member:

The casing 1 connected by revolute pair 7 and case lid 4;

Fixed head 11: the bottom of described casing 1 is fixed in its lower end; Described fixed head 11 is circular arc and vertically places.

Elastic webbing 8: its curling layout and two ends are mutually overlapping, the one end being wherein positioned at inner side is fixed on described fixed head 11 upper end by holding screw 10, and the outside, one end being positioned at outside has one section of dentalation;

Gear shaft 12: described gear shaft 12 upper end has knob 2, the lower end of described gear shaft 12 to be positioned at bottom described casing 1 and can freely to rotate, and it is fixed with 2 gears 3, described gear 3 can engage with described dentalation.

This device also comprises the lock handle 5 be positioned at outside described case lid 4, is positioned at the snap close 6 on described case lid 4 and is positioned at the structure lockhole 9 that described casing 1 can engage with described snap close 6.

The using method of this clamping device is as follows: before fixing cigarette, rotate backward described knob 2 and (direction that this device is clamped is defined as forward, the direction that this device is fluffed is defined as oppositely), drive described gear shaft 12 and on 2 gears 3 rotate, thus drive described elastic webbing 8 to move by the dentalation on described elastic webbing 8, overlapping place, described elastic webbing 8 two ends is diminished, and inside diameter becomes large.Again cigarette filter stick is positioned over upward, in a vertically downward fashion in the middle of described elastic webbing 8.Rotate forward described knob 2, drive described gear shaft 12 and on 2 gears 3 rotate, thus drive described elastic webbing 8 to move by the dentalation on described elastic webbing 8, make overlapping place, described elastic webbing 8 two ends become large, inside diameter reduces.Regulate degree of rotation according to the diameter of cigarette, not easily to loosen and cigarette filter stick stops without when obvious distortion to cigarette.

Certainly, device of the present utility model also can carry out the size of the diameter that adjustable elastic band 8 surrounds by aut.eq..Namely, described gear shaft 12 can not only lean on manual adjustments knob 2 to rotate, but can be rotated by the electric device of such as motor and so on, the unlatching of motor can be controlled by switch, or inside elastic webbing 8, pressure transducer is set, carry out the start and stop of feedback regulation motor according to the size of clamp pressure, realize the semi-automatic adjustment of clamping diameter thus.

Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to the utility model embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here cannot give exhaustive to all embodiments.Every belong to the technical solution of the utility model the apparent change of extending out or variation be still in the row of protection domain of the present utility model.
