Abstract
The utility model provides a lock-self pipe twist with a sliding bar, which uses a convex wheel and a handle which are squeezed to be served as a limitator and uses a pressure rod as a pressing device. The distance of a jaw can be adjusted by using the push and pull method. The workpiece can be clamped to be locked instantly no matter how the external dimension of the workpiece is changed; after the workpiece is locked, both directions of the workpiece can be rotated.
Description
The utility model provides a kind of improved plumber's pipe wrench.It is to limit device with the extruding of cam and handle, sliding thick stick self-locking pipe wrench that can positive and negative both direction turn workpiece behind the locking workpiece.
Existing pipe wrench is regulated the jaw distance with adjustable screw.Its shortcoming is that governing speed is slow, the difficult adjustment.Especially workpiece size changes and just seems more not when frequent.And can only be to a direction turn workpiece.Therefore existing pipe wrench is not desirable plumber's instrument, needs improvement badly.
Task of the present utility model provides a kind of follow-on pipe wrench.No matter how frequent it is that the overall dimensions of workpiece change, this pipe wrench is as long as one draw one to push away moment and workpiece can be clamped, and locked.And can positive and negative both direction rotational workpieces.
The utility model is achieved in that
This pipe wrench is by fixed caliper, handle, and moving caliper, device for exerting, positioning sliding block five parts are formed.Handle and fixed nip are integrated, and positioning sliding block is connected by device for exerting with moving caliper, all can slide on handle simultaneously.The device for exerting postbrachium is ad hoc brake cam, and cam did not contact with handle when moving caliper slided on handle with positioning sliding block, and the handle of exerting pressure when needing clamping work pieces is upwards moved, and cam contacts with handle.After positioning sliding block can not slide, moving caliper had obtained a motive force forward, and workpiece is clamped, and turn handle workpiece can be followed rotation.
The utility model is described in further detail in conjunction with the accompanying drawings:
Fixed caliper is by handle (5), and fixed nip (1) is formed.Moving caliper (14) is made up of movable clamp port (2) open-work (3) identical with handle (5) physical dimension.Device for exerting is made up of the forearm of exerting pressure (11), effort handle (10), the postbrachium of exerting pressure (8) and postbrachium tail end one cam (12).Moving caliper (14) connects the forearm of exerting pressure by connecting axle (6).Connect exert pressure forearm (11) and postbrachium (8) by connecting axle (7), postbrachium is connected with positioning sliding block (13) by connecting axle (9).Moving caliper (14) device for exerting can slide on handle after positioning sliding block is connected as a single entity simultaneously.When the pulling positioning sliding block when (13) jaw magnify when identical workpiece and enter in quiet, the movable clamp port with the workpiece overall dimensions, upwards move the handle of exerting pressure (10) again, the cam of the postbrachium of exerting pressure contacts the back and has produced powerful extrusion force positioning sliding block can not be slided with handle.The angle α of forearm (11) and postbrachium (8) increases the elongation of two arms and has produced a thrust forward, and this tries hard to recommend moving moving caliper (14), and jaw obtained a very big clamping force workpiece was clamped this moment.α can be locked in workpiece in the jaw after 180 °.The turn handle can positive and negative both direction turn workpiece.If with above-mentioned opposite, operate the handle of exerting pressure and to remove the clamping force of jaw workpiece.
Claims (2)
1, a kind of sliding thick stick self-locking pipe wrench, it is made up of fixed caliper, moving caliper, device for exerting, positioning sliding block, it is characterized in that:
A. fixed caliper is made up of fixed nip (1) and handle (5).
B. moving caliper (14) is made up of open-work (3) and the movable clamp port (2) identical with handle (5) physical dimension.
C. device for exerting, by the handle of exerting pressure (10), compression arm (11), compression arm (8) is formed.
D. positioning sliding block (13), it is identical with the appearance and size of handle (5) to have its size of an open-work (4).
2, according to right 1 described sliding thick stick self-locking pipe wrench, it is characterized in that: the tail end of the compression arm of device for exerting (8) has a brake cam (12), moving caliper (14), device for exerting, positioning sliding block is linked into an integrated entity and can be slided on handle by connecting axle (6), (7), (9).
