Description

A kind of improved fixture
Technical field
The utility model belongs to fixture, and in particular to a kind of improved fixture.
Background technique
Fixture is most common tool during people live, work.Existing fixture, which includes two, to be had elasticity and opens one The clamp arm of tentering degree pinches pressure clamp arm by hand to clamp article when use, unclamps clamp arm, and clamp arm can restore former under the effect of elasticity Shape.Due to the opening amplitude of two clamp arm be it is fixed, when clamping open amplitude close larger size article with it when, two clamp arm The distance of relative motion is smaller, when only elastic force need to be overcome to apply less power to clamp arm, and clamp smaller size article, two folders The distance of arm relative motion is larger, then to apply biggish power, if the clamping lesser article of size for a long time, hand can be obvious It feels fatigue and aches.
Utility model content
The purpose of this utility model is to provide the improved fixtures that a kind of adjustable clamp arm opens amplitude.
The technical scheme adopted for realizing the purpose of the utility model is as follows:
Improved fixture provided by the utility model, including the first and second two clamp arm, one end of two clamp arm is all provided with There is interconnecting piece, wherein the interconnecting piece of the first clamp arm is equipped with accommodating chamber, a part of the interconnecting piece of the second clamp arm protrudes into described first It is in the accommodating chamber of clamp arm and hinged by the interconnecting piece of connecting shaft and the first clamp arm, in the accommodating chamber of first clamp arm The interconnecting piece that the eccentric block and second clamp arm that are located above the connecting shaft are equipped with by hinge axis leans, and described first The interconnecting piece of clamp arm is externally provided with the knob with the hinge axis connection of the eccentric block, and first, second in the accommodating chamber Spring is equipped between the interconnecting piece of clamp arm.
Accommodating chamber on the interconnecting piece of first clamp arm includes parallel front and back cavity wall and arc-shaped cavity wall up and down, described The interconnecting piece of the second clamp arm protruded into the accommodating chamber of the first clamp arm includes being close to the front and back cavity wall of the accommodating chamber and upper respectively The anterior-posterior plane and upper and lower arc surface of lower cavity wall, so that the accommodating chamber of relatively described first clamp arm of the interconnecting piece of second clamp arm When movement, the interconnecting piece of second clamp arm always seals the accommodating chamber of first clamp arm.
Wavy bump, the second clamp arm connection are equipped with around eccentric block in the first clamp arm accommodating chamber Portion is equipped with arc-shaped convex block and leans with the bump on the eccentric block.
Beneficial effect
1, the utility model structure is simple, easy to use, and the opening between the first, second clamp arm can be adjusted by eccentric block Amplitude whether clamps large scale article or clamping small size article, need to only be adjusted to two clamp arm and be suitble to clipped object product Opening amplitude, the smallest dynamics clamping article can be used in this way, avoid causing hand fatigue occur to ache because working long hours The phenomenon that pain.It needs to continue clamping article in some cases, at this moment knob can be locked the folder for keeping two clamp arm to article Tight state saves the clamping force of hand.
2, in relative motion, the interconnecting piece of the second clamp arm begins the interconnecting piece of the first, second clamp arm in the utility model The accommodating chamber sealing of first clamp arm at last, can prevent water and dust from entering in accommodating chamber, damage spring, eccentric block in accommodating chamber Equal components, and harmful bacteria is bred in accommodating chamber, this has special significance to clamping food.
The utility model is not only suitble to food service industry, is also suitable for city dust alleviation work.
The technical solution of the utility model is further illustrated with reference to the accompanying drawing.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the lateral plan of the first clamp arm in the utility model.
Specific embodiment
See Fig. 1, Fig. 2, improved fixture provided by the utility model, including the first and second two clamp arm 1,1 ', two One end of clamp arm 1,1 ' is respectively equipped with interconnecting piece 2,2 ', wherein the interconnecting piece 2 of the first clamp arm 1 is equipped with accommodating chamber a, accommodating chamber a packet Include parallel front and back cavity wall 203,204 and arc-shaped cavity wall 201,202 up and down, one of the interconnecting piece 2 ' of second clamp arm 1 ' Divide the accommodating chamber a for protruding into first clamp arm 1 interior and hinged by connecting shaft 3 and the interconnecting piece 2 of the first clamp arm 1, institute State the eccentric block 4 and second folder for being equipped in the accommodating chamber a of the first clamp arm 1 by hinge axis 5 and being located at 3 top of connecting shaft The interconnecting piece 2 ' of arm 1 ' leans, and the hinge axis 5 of eccentric block 4 is mounted on the interconnecting piece 2 of the first clamp arm 1 by the way of tighter On, the interconnecting piece 2 of first clamp arm 1 is externally provided with the knob 6 connecting with the hinge axis 5 of the eccentric block 4, is located at the receiving Spring 7 is equipped between the interconnecting piece 2,2 ' of the first, second clamp arm 1,1 ' in chamber a;It is described to protrude into the first clamp arm accommodating chamber a The interconnecting piece 2 ' of second clamp arm 1 ' includes the front and back cavity wall 203,204 and upper and lower cavity wall 201,202 for being close to the accommodating chamber a respectively Anterior-posterior plane 203 ', 204 ' and arc surface 201 ', 202 ' up and down so that the interconnecting piece 2 ' of second clamp arm 1 ' is described the In the accommodating chamber a of one clamp arm 1 when movement, the interconnecting piece 2 ' of second clamp arm 1 ' is always by the accommodating chamber a of first clamp arm 1 Sealing;Wavy bump 401, second clamp arm 1 ' are equipped with around eccentric block 4 in the first clamp arm accommodating chamber a Interconnecting piece 2 ' be equipped with arc-shaped convex block 205 ' lean with the bump 401 on the eccentric block 4.
When the utility model is used, if to clamp the article of larger size, rotatable knob 6 is by the protrusion of eccentric block 4 Partially away from the interconnecting piece 2 ' of the second clamp arm 1 ', the amplitude that the first, second clamp arm 1,1 ' is opened under the action of spring 7 is maximum; If clamping the article of smaller size, rotatable knob 6 is by the protrusion part of eccentric block 4 against the interconnecting piece of the second clamp arm 1 ' 2 ' and overcome the active force of spring 7, makes the opening amplitude of the first, second clamp arm 1,1 ' close to folded article, clamped in this way with hand When article, need to only pinch pressure clamp arm a little can easily clamp article.It needs to continue clamping article in some cases, at this moment can will revolve Button 6, which is locked, makes two clamp arm 1,1 ' keep saving the clamping force of hand to the clamped condition of article.
Due to being equipped with wavy bump 401, the second clamp arm 1 ' around the eccentric block 4 in the first clamp arm accommodating chamber a Interconnecting piece 2 ' be equipped with arc-shaped convex block 205 ' lean with the bump 401 on the eccentric block 4, when first, second press from both sides It can be better maintained its state after the opening amplitude adjusted of arm 1,1 ' is good, prevent eccentric block 4 from skidding.
When being moved in the accommodating chamber a of the first clamp arm 1 due to the interconnecting piece 2 ' of the second clamp arm 1 ', the connection of the second clamp arm 1 ' Portion 2 ' always seals the accommodating chamber a of first clamp arm 1, can prevent water and dust from entering in accommodating chamber a, damages accommodating chamber The components such as spring 7, eccentric block 4 in a, and harmful bacteria is bred in accommodating chamber a.
