Abstract
The utility model relates to a two-way ratchet wheel spanner, wherein one end of a sleeve spanner is provided with an internal hexagonal hole which is matched with a bolt head, the other end is provided with a fine gear spline shaft tube, one end of a handle is provided with a tube bottom and a round tube sleeved on the fine gear spline shaft tube, a ratchet wheel is sleeved on the fine gear spline shaft tube, gears of the ratchet wheel is an equilateral gear, a circlip slot is arranged outside a tube port of the spline shaft tube, a circlip is arranged in the circlip slot, a strip-shaped sliding pawl which is vertical to the length direction of the axial cord of the ratchet wheel and the handle penetrates through the round tube on the handle, two ends of the sliding pawl directing to the ratchet wheel are respectively provided with pawls matched with the ratchet wheels, the middle section of one side of the sliding pawl opposite to the ratchet wheel is provided with two locating dents, and a spring ball matched with the locating dents is arranged on the handle. The gear of the ratchet wheel of the two-way ratchet wheel spanner is the equilateral gear, the pawl is the strip-shaped sliding pawl, two ends of the strip-shaped sliding pawl are respectively provided with the pawls, once the strip-shaped sliding pawl is sleeved into a bolt head, and the two-way ratchet wheel spanner not only can rotate on the positive direction for use, but also can rotate on the negative direction for use through pushing the sliding pawl.
Description
Technical field
The utility model relates to the ratchet and pawl of a kind of ratchet spanner, particularly a kind of ratchet spanner.
Background technology
Ratchet spanner has sleeve to pull and pulls the handle that links to each other with sleeve, and sleeve is pulled and is with ratchet, is hinged with the ratchet that matches with ratchet on the handle.During use, when handle rotated to direction, ratchet can be inserted into and promote ratchet between the adjacent a pair of ratchet of ratchet to drive the sleeve switching moving, be used for fastening or dismantle bolt, when handle rotated to another direction, ratchet was beated on the ratchet of ratchet, and ratchet is motionless.Ratchet spanner can be easily fastening after being enclosed within bolt head or be dismantled bolt.The sleeve of ratchet spanner of the prior art pull and handle between ratchet and pawl in, the ratchet of ratchet is unequal-sided helical teeth, ratchet has only one, be hinged on the handle, ratchet spanner is after being enclosed within bolt head, handle can only be moving to the switching of a direction rotating band moving sleeve, as rotating to another direction, need pull sleeve of the present utility model from the bolt head that is enclosed within and take off, be enclosed within again after the upset on the bolt head and could rotate to another direction, so ratchet spanner of the prior art after putting bolt head, only is suitable for fastening or dismantles a kind of operation of bolt, can not also can dismantle bolt by fastening bolt.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, to propose a kind of forward rotation fastening bolt that can be used for and also can be used for the reversible ratcheting tool that backward rotation is dismantled bolt after putting bolt head.
The utility model is realized with the following method.
Reversible ratcheting tool has sleeve to pull and pulls the handle that links to each other with sleeve, the end that sleeve is pulled has the inner hexagonal hole that matches with bolt head, the other end that sleeve is pulled has the cylindrical shape serration splined shaft that communicates with inner hexagonal hole, one end of handle is connected with the identical cylinder of external diameter that external diameter and ratchet carriage are pulled, the axis of described cylinder and the length direction of handle are perpendicular, the tube of cylinder has at an end and to be enclosed within the circular hole that matches with the serration splined shaft on the serration splined shaft, be with the ratchet in above-mentioned cylinder on the serration splined shaft with internal spline axis hole, the tooth of described ratchet is equilateral tooth, there is the jump ring groove in the nozzle outside of above-mentioned serration splined shaft, in the jump ring groove jump ring is arranged, cylinder side on the handle is installed with and the axis of ratchet and the perpendicular bar shaped slip ratchet of length direction of handle, the slip ratchet has the ratchet that matches with ratchet respectively towards the two ends of ratchet one side, the slip ratchet stage casing of ratchet one side dorsad has two dihedral angle location pits, and the spring ball that matches with the location pit is arranged on the handle.
During use, the utility model is enclosed within on the bolt head, the slip ratchet is pushed to a side, allow spring ball on the handle enter the slip ratchet dorsad in the location pit of ratchet one side, the ratchet of ratchet one end that slides this moment inserts between a pair of ratchet that a side is adjacent on the ratchet.When the forward rotation handle, because ratchet is stuck on the ratchet on the ratchet, ratchet constraint ratchet makes the bolt head forward rotation; When the backward rotation handle, the ratchet on the ratchet can promote to slide ratchet in the restriction range of location pit, beats on ratchet along its length direction, removes the constraint to ratchet, makes the bolt head can not backward rotation.If the slip ratchet is pushed to opposite side, allow spring ball on the handle enter the slip ratchet dorsad in another location pit of ratchet one side, the ratchet of the ratchet other end of then sliding inserts between the adjacent a pair of ratchet of opposite side on the ratchet, make the utility model can only be to backward rotation, can not be to forward rotation.
The tooth of ratchet of the present utility model is equilateral tooth, ratchet is a bar shaped slip ratchet, and the two ends of bar shaped slip ratchet have ratchet respectively, once being inserted in bolt head, can the utility model can forward rotation be used by promoting the slip ratchet, can backward rotation use again.
Below in conjunction with accompanying drawing, the utility model is further described.
