Abstract
The utility model discloses a kind of tongs, including hanging ring, the lower end of hanging ring is fixedly connected with davit, and the lower end of the davit is connected with symmetrical caliper by shaft；The caliper includes diagonal brace, perpendicular support and stull, and stull is mutually perpendicular to perpendicular support；The davit is socketed with movable sleeve, connecting rod is equipped between the movable sleeve and the lower end of diagonal brace, the both ends of the connecting rod are connect with movable sleeve and diagonal brace by shaft respectively.The beneficial effects of the utility model：The tongs of this kind of structure, efficiently with work pieces mate and dismounting, can improve the efficiency of work by manually；It is actively set under the action of back-moving spring naturally downward crimper body, ensure that the safety of lifting.
Description
Technical field
The utility model is related to a kind of suspender of lifting workpiece, specifically a kind of tongs.
Background technology
The suspender for being presently used for lifting I-steel is generally the structure of tongs, this kind of tongs by shaft directly with lifting
Device connects, and safety coefficient is not high during lifting；Also there is itself with dynamic tongs, but this kind of tongs operation is not
Just, the efficiency of work is reduced.
For this purpose, applicant proposed a kind of technical solutions, and provide a kind of tongs.
Invention content
The purpose of this utility model is to provide a kind of tongs, which can automatically lock the workpiece such as I-steel, tear open
Dress is more quick, improves safety coefficient and the efficiency of work.
To achieve the above object, the technical solution of the utility model includes hanging ring, and the lower end of hanging ring is fixedly connected with davit,
The lower end of the davit is connected with symmetrical caliper by shaft.
The caliper includes diagonal brace, perpendicular support and stull, and stull is mutually perpendicular to perpendicular support.
The davit is socketed with movable sleeve, between the movable sleeve and the lower end of diagonal brace be equipped with connecting rod, the two of the connecting rod
End is connect with movable sleeve and diagonal brace by shaft respectively.
Further, the lower end of the movable sleeve connects by the lower end of back-moving spring and davit
Further, the upper surface of the stull is equipped with non-slip mat.
Due to the adoption of the above technical scheme, the beneficial effects of the utility model are：The tongs of this kind of structure can pass through hand
It moves efficiently with work pieces mate and dismounting, improves the efficiency of work；It is actively set under the action of back-moving spring and is pressed downward naturally
Clencher body ensure that the safety of lifting.
Description of the drawings
The utility model is described further in conjunction with attached drawing.
Fig. 1 is the structural schematic diagram of the utility model.
In figure：1, hanging ring, 2, davit, 3, caliper, 301, diagonal brace, 302, perpendicular support, 303, stull, 304, non-slip mat, 4, living
Dynamic set, 5, connecting rod, 6, spring.
Specific implementation mode
As shown in Figure 1, the lower end of hanging ring 1 is fixedly connected with davit 2, the lower end of the davit 2 is connected with symmetrically by shaft
Caliper 3, caliper 3 includes diagonal brace 301, perpendicular support 302 and stull 303, and stull 303 is supportted 302 and be mutually perpendicular to perpendicular, stull 303
Upper surface is equipped with non-slip mat 304.Davit 2 is socketed with movable sleeve 4, and connecting rod 5 is equipped between movable sleeve 4 and the lower end of diagonal brace 301,
The both ends of connecting rod 5 are connect with movable sleeve 4 and diagonal brace 301 by shaft respectively, the lower end of movable sleeve 4 by back-moving spring 6 with
The lower end of davit 2 connects.
When in use, movable sleeve 4 can be moved up, caliper 3 opens and work pieces mate, and during lifting, caliper 3 is certainly
It can will be by movable sleeve 4 by tongs and workpiece after completing to lift with workpiece firm connection under the action of body structure and spring 6
Quickly separation.
