Description

Square bench clamp

Technical Field

The utility model belongs to the technical field of bench clamps, and particularly relates to a square bench clamp.

Background

The existing bench clamp movable jaw and fixed jaw in the market are both cuboid, the contact surfaces of the two are rectangular planes, and only two sides of an article can be fixed, so that the bench clamp is better used when an object with a regular appearance is fixed, but the bench clamp is not well fixed to an object with an irregular appearance. And the fixed object that can not three-dimensionally is not very much, and when operating the object, article can the skew probably, can take place to roll when reation kettle operates, and is not very safe and practical, can not satisfy the user demand in laboratory. Therefore, there is a need for square bench clamps to solve the above problems.

Disclosure of Invention

In view of the above-mentioned problems with the background art, the present utility model has as its object: aims to provide square bench clamp.

In order to achieve the technical purpose, the utility model adopts the following technical scheme:

the utility model provides a square bench vice, includes fixed pincers body, fixed pincers body is equipped with the adjustment tank, adjustment tank internal movable mounting has the lead screw, the lead screw is connected with screw-nut, screw-nut is connected with movable jaw, fixed pincers body is installed fixed jaw in corresponding movable jaw department, movable jaw all is equipped with L type pincers groove with fixed jaw, and movable jaw is mutual crisscross mosaic structure setting with fixed jaw.

Further limited, the both sides of lead screw run through fixed pincers body and extend to its outside, wherein one side the lead screw is connected with the dwang socket, install the dwang in the dwang socket, the opposite side the lead screw is equipped with the limit head.

Further defined, both sides of the rotating rod are connected with rotating rod nuts through threads.

Further defined, the movable jaw and the fixed jaw are arranged in a square structure.

Further limited, both sides of the fixed clamp body are connected with a fixed base, and a screw () is installed in the fixed base.

The beneficial effects of the utility model are as follows: the movable bench clamp is movable, the L-shaped clamp grooves are formed in the clamp jaws, so that the four surfaces are fixed, the movable bench clamp can be used for fixing cylinders such as multi-type reaction kettles or other irregular objects, the objects can be better fixed in a three-dimensional mode, the problems that a common bench clamp is not easy to fix and fall off to incline when facing the irregular objects are solved, the safety and the high efficiency are achieved, the experimental operation is simplified, and the wide market prospect is achieved.
