Description
The utility model relates to a kind of manual wrench, especially the combination wrench of the narrow multiple shape workpiece of local degree of tightness of application space.
Existing adjustable wrench and pipe wrench and solid wrench, the defective that exists is: pull mouthful, the jaw folding is time-consuming bothersome, the degree of tightness workpiece is extremely inconvenient, and very easily make the hexagonal (hexagon)nut mill lose corner angle, in the space narrow place especially inconvenience use, though solid wrench can use in narrow place in the space,, its size is single, uses also very inconvenient; A kind of monkey wrench, the patent No.: 93244943, though improve to some extent,, the defective that monkey wrench exists is fairly obvious: chucking workpiece handle swing angle degree is big, and degree of tightness workpiece size scope is little, and pulling mouth can not change with the workpiece size.The narrow place in the space, still inconvenience is used.
At above-mentioned deficiency, the utility model provides a kind of function that integrates adjustable wrench, solid wrench and pipe wrench and monkey wrench, and narrow place still can make things convenient for the combination wrench of the various type shape of degree of tightness workpiece freely in the space.Its advantage is: the chucking workpiece handle anglec of rotation is little, degree of tightness workpiece size scope big, pull mouthful folding can change with the workpiece size.Thereby solved the difficult problem that the local inconvenience narrow in the space of adjustable wrench, pipe wrench is used.
For realizing this purpose, the technical solution of the utility model shows as:
A kind of combination wrench is by handle with pull mouthful movable part and the garden pin connects and composes.Pull the shape approximation greater-than sign "＞" or the is less than "＜" of mouthful movable part, the angle that the both sides face forms is less than 90 degree, and optimum angle 60 is spent.The inboard of pulling mouthful movable part is provided with three medial surfaces, and press isogonism or isogonism link to each other, pull on three medial surfaces of mouthful movable part and establish teeth or do not establish teeth, pull the position that mouthful movable part one end combines with handle and be provided with groove, be convenient to handle and be rotated around the garden pin; Handle pull that the oral area position is made as lonely shape side, lonely shape side is provided with teeth or does not establish teeth.Use for the ease of the place more narrow in the space; Be connected with the slidable adjustment positioner at handle on mouthful movable part with pulling, single using and dual-purpose slidable adjustment positioner arranged, list is used the slidable adjustment positioner, is made of connecting rod, sliding part, pin etc.; Dual-purpose slidable adjustment positioner is made of connecting rod, sliding part, spring, pin etc.Reach the adjusting location by be slidingly connected bar or sliding part and pull the purpose that mouthful size adapts to workpiece size.
Provide four embodiment of the present utility model below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of the utility model embodiment one;
Fig. 2 is the right side view of Fig. 1;
Fig. 3 is the structural representation of the utility model embodiment two;
Fig. 4 is the structural representation of the utility model embodiment three;
Fig. 5 is the structural representation of the utility model embodiment four.
Embodiment one constitutes one by pulling a mouthful movable part (1), handle (2) and garden pin (3).An end of pulling a mouthful movable part (1) is provided with the hole, garden, and is provided with and is convenient to the groove of handle (2) around garden pin (3) rotation, and mouthful thickness of pulling of groove width and handle (2) matches.Pull a mouthful movable part (1) and handle (2) and constitute one, so pull a mouthful movable part (1) and handle (2) all is active by garden pin (3).Also can implement the method for sound exchange: on handle (2), establish groove, do not establish groove pulling on mouthful movable part (1).
Embodiment two is for the workpiece that adapts to wider size designs, all is connected with at the two ends of handle (2) and pulls a mouthful movable part (1), and the concrete structure at two ends is identical with embodiment one by garden pin (3), but the size difference, two ends are of a size of small one and large one.
Embodiment three designs for adapting to the more narrow place use in space, be to constitute jointly by pulling a mouthful movable part (1), handle (2), garden pin (3) and connecting rod (6), spring (7), pin (8), sliding part (9) etc., by bar that is slidingly connected (6) or sliding part (9), be releasable workpiece, reach the dual regulation location and pull mouthful purpose of size.
Embodiment four is single designs of pulling the mouth size with the adjusting location, be to constitute jointly by pulling a mouthful movable part (1), handle (2), garden pin (3) and connecting rod (6), pin (8) (10), sliding part (9) etc., by slip sliding part (9), be releasable workpiece, reach and regulate the purpose that the mouth size is pulled in the location.
The utility model mouthful blocks workpiece as long as will pull when the degree of tightness workpiece, turning handle (2) can reach the purpose of free degree of tightness workpiece.
