Abstract
The multi-functional ratchet wrench includes a wrench and a handle. The main point of the technology is that the tail part with along-contrary torque output buttons is inserted into the opening groove of the handle head, and the tail part is hinge connected with the opening groove of the handle head. The self-resetting moving pin positioned at the handle drives the base plate to control the axial displacement of the locating pin. The locating pin is controlled to move in or out the indexing locating hole of the wrench tail, which enables the wrench to rotate around the center pin or to be fixed with the handle. The utility model has a simple structure, which is easy to be operated and used. The utility model overcomes the defect in the prior art that the wrench and the handle cannot form a clamp. The utility model enables the wrench and the handle to form a proper angle, which obviously improves the service performance and expands the applied range.
Description
Technical field
The utility model relates to a kind of loading, unloading, maintenance tool, particularly a kind of equipment, vehicle attachment tools class multifunctional ratchet wrench.
Background technology
At present, in the installation of various device, vehicle, dismounting, maintenance activity, often use comings and goings spanner (spanner have adjustable pull mouthful), fork spanner (spanner pull mouthful fixing non-adjustable) and movable fork spanner (spanner has and fixedly pulls mouth, but spanner and pull the ratchet that the energy one-directional rotation is set between mouth).Ratchet spanner is used one of more movable fork spanner exactly.Existing ratchet spanner mainly contains two kinds of versions: first spanner and trigger piece are integral type, and it two is that spanner and trigger piece are split type, and promptly spanner adopts inserting mode to combine with trigger piece.Yet the ratchet spanner of any form, its spanner are pulled mouthful center and the vertical line of trigger piece is on the same straight line, can't form angle.Therefore, just do not had the operating space, brought inconvenience for loading, unloading, maintenance in some narrow operation places.
The utility model content
The purpose of this utility model provides a kind of multifunctional ratchet wrench, its reasonable in design, simple to operate, easy to use, the spanner of prior art existence and the shortcoming that trigger piece can not form angle have been overcome effectively, spanner can form required angle operation with trigger piece, significantly improves its serviceability and widens the scope of application.
The purpose of this utility model is achieved in that this device comprises spanner and trigger piece, its technical essential is: the spanner afterbody that has along opposing torque output knob is plugged in the trigger piece head open slot, and it is hinged by central pin shaft, utilize the axial displacement of the active pin shaft drive handling substrates alignment pin that resets certainly on the trigger piece, the control alignment pin withdraws from or enters the calibration locating hole of spanner afterbody, makes spanner rotate or be fixed together with trigger piece around central pin shaft.
The bottom of the active pin shaft that resets certainly on the described trigger piece connects substrate, its upper end assembling back-moving spring.
Because the utility model is improved on the architecture basics of existing ratchet spanner, so be easy to realize.It is that the spanner of existing ratchet spanner and the connected structure of trigger piece are redesigned, and it is hinged by central pin shaft, utilize the active pin shaft drive substrate that resets certainly on the trigger piece to move back and forth, the calibration locating hole of spanner afterbody is withdrawed from or enters in the axial displacement of control alignment pin, make spanner rotate or be fixed together with trigger piece around central pin shaft, spanner can form required angle operation with trigger piece.This apparatus structure is reasonable in design, can keep former ratchet spanner advantage simple to operate, easy to use, has overcome the spanner of prior art existence and the shortcoming that trigger piece can not form angle again effectively.When operation, can adjust the angle that spanner and trigger piece form as required,, also can satisfy special job requirements, significantly improve its serviceability and widen the scope of application in some narrow places.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a kind of concrete structure schematic diagram of the present utility model.
Fig. 2 is the cutaway view of Fig. 1 along the A-A line.
The specific embodiment
Describe the concrete structure of the present utility model and the course of work in detail according to Fig. 1-2.This device comprises spanner 2 and trigger piece 5.Wherein the spanner 2 and the ratchet basic structure of fixedly pulling the energy one-directional rotation between mouth still keep the characteristics of former ratchet spanner.Fixedly pulling specification, the shape of mouth should select according to actual instructions for use.Spanner 2 afterbodys that have along opposing torque output knob 1 are fan-shaped sheet distribution, at the center of fanning strip axis hole are set, and a plurality of calibration locating holes are set on the circular arc of peripheral same radius.Trigger piece 5 heads are processed with open slot, and the bottom that parallels a side with the opening groove face is processed with the substrate groove, and the bottom of the active pin shaft 6 that resets certainly on the trigger piece 5 connects substrate 8, its upper end assembling back-moving spring 7.Spanner 2 fan-shaped sheet afterbodys are plugged in the trigger piece 5 head open slots, and by central pin shaft 3 that it is hinged.Utilize the active pin shaft 6 drive substrates 8 that reset certainly on the trigger piece 5 to move back and forth the axial displacement of control alignment pin 4.Alignment pin 4 withdraws from the calibration locating hole of spanner afterbody, can make spanner 2 around central pin shaft 3 rotations.Alignment pin 4 enters in the calibration locating hole of spanner 2 afterbodys, and spanner 2 is fixed together by the position and the trigger piece 5 of the calibration locating hole on it, forms needed connection angle.
During use, at first push, make it to drive substrate 8 control centre's bearing pins 3 and alignment pin 4 and move axially, withdraw from the central shaft hole and the calibration locating hole of spanner 2 afterbodys fully until it to being displaced downwardly to range from resetting active pin shaft 6.Replaceable at this moment, the required spanner 2 of loading and unloading.Stop to push, the active pin shaft 6 that resets certainly automatically resets under the elastic force effect of spring, finishes spanner 2 tasks of changing.
If push downwards from resetting active pin shaft 6, make it to being displaced downwardly to certain stroke, drive substrate 8 control alignment pins 4 and move axially, until the calibration locating hole that withdraws from spanner 2 afterbodys fully, central pin shaft 3 still is retained in the central shaft hole of spanner 2 afterbodys.Can make spanner 2 rotate to around central pin shaft 3 to need angle this moment, align corresponding calibration locating hole after, stop to push.Active pin shaft 6 automatically resets under the elastic force effect of spring 7, and spanner 2 is fixed together by the position and the trigger piece 5 of the calibration locating hole that is positioned on it, realizes angular transition.
Claims (2)
1, a kind of multifunctional ratchet wrench, comprise spanner and trigger piece, it is characterized in that: the spanner afterbody that has along opposing torque output knob is plugged in the trigger piece head open slot, and it is hinged by central pin shaft, utilize the axial displacement of the active pin shaft drive handling substrates alignment pin that resets certainly on the trigger piece, the control alignment pin withdraws from or enters the calibration locating hole of spanner afterbody, makes spanner rotate or be fixed together with trigger piece around central pin shaft.
2, multifunctional ratchet wrench according to claim 1 is characterized in that: the bottom of the active pin shaft that resets certainly on the trigger piece connects substrate, its upper end assembling back-moving spring.
