Abstract
The utility model discloses a free-reverse drive type monkey-spanner which belongs to a tool spanner whose handle can return freely, comprising a monkey-spanner and a handle. The utility model is characterized in that a movable spanner head with a ratchet wheel is hinged in the groove at the front end of the handle and meshed with a ratchet pawl hinged in the same groove; a supporting spring reed is installed at one side end of the ratchet pawl to cause the ratchet pawl and the ratchet wheel to keep the meshing state. That a nut is locked is completed by that the monkey-spanner is not needed to be off the nut when using, and the work efficiency is enhanced.
Description
The utility model belongs to a kind of tool wrench, but is a kind of monkey wrench of free return stroke specifically, mainly is to have done improvement on the basis to existing structure.
It is to be made of live spanner and handle integral body for the monkey wrench of existing use.This kind adjustable wrench can only driving handle unidirectional tightened-up direction be pulled as in use, when pulling certain position, must withdraw from spanner, readjusts angle and screws again and pull, and finishes locking nut and need withdraw from repeatedly repeatedly, brings inconvenience for the person of manipulating.
The purpose of this utility model provides a kind of improved free return stroke formula adjustable wrench, utilizes being connected of live spanner and handle articulated structure, and the relative handle of spanner that makes it to live is static, and driving handle rotates freely, realizes the effect of locking nut fast.
For achieving the above object, the utility model is realized by following measure: adopt movable jaw (1) and handle (6) adjustable wrench dimerous, and link a ratchet (4) that has hinged setting in the same with it groove of movable jaw (1) of ratchet (3) mesh in the groove of the leading section of handle (6); At ratchet (4) one sides support spring sheet (8) is installed in addition, makes it to act on ratchet (4) and remain in the engagement shape with ratchet (3).
The form of this structure mainly utilizes the effect of support spring sheet to keep engagement by the ratchet of ratchet on the spanner of living and handle end, the direction rotation of driving handle inverse time.Just align an angle position, be convenient to the carrying out of next action, realize locking action.
The utility model has outside the performance of common adjustable wrench compared to existing technology, also has the handle of making free return stroke and pulls spanner work, regulates arbitrarily and pulls angle, do not need retraction operation repeatedly, can reach the purpose of locking nut, reduce and stirred number of times, improve operating efficiency.
Description of drawings:
Fig. 1 is this novel topology view.
Embodiment is further described in conjunction with the accompanying drawings:
Show the overall structure of free return stroke formula adjustable wrench by Fig. 1, adopted the semicircle curved surface of movable jaw (1) bottom to be provided with ratchet (3), be hinged on by bearing pin (2) in the groove of handle (6) leading section, movable jaw (1) is rotated arbitrarily by the hinged place.In the same groove of ratchet (3) bottom, also be hinged with ratchet (4), its preceding claw and ratchet (3) engagement by bearing pin (5).Remain on certain angle position with respect to spanner (1) qualification of living in order to make it handle (6), and support spring sheet (8) is installed in the corresponding position of groove lower end, fixing by screw (7), thus having guaranteed that ratchet (4) and ratchet (3) remain is in engagement.When operation, as long as behind the opening part insertion nut with movable jaw (1), just can rotate by free driving handle (6).Lock as clockwise direction, ratchet this moment (4) is under the effect of spring leaf (8), make it to be in engagement with ratchet (3), when reaching certain position, inverse time direction turning handle (6) then, ratchet (4) is slided break away from ratchet (3), treat and ratchet (3) engagement of arbitrary position, be in next duty.
The ratchet (3) of above-mentioned movable jaw (1) part is except that along the semicircle position is provided with, and also 1/4 circular portion at the spanner position is provided with ratchet as required, makes it the effect that handle reaches free return stroke equally.
Claims (2)
1, free return stroke formula adjustable wrench comprises that movable jaw and handle two parts constitute, hinged one movable jaw (1) that has ratchet (3) in the groove of (6) leading section that it is characterized in that having handle, and with same groove in ratchet (4) engagement of hinged setting; Ratchet (4) one sides are equipped with support spring sheet (8), make it to act on ratchet (4) and remain in the engagement shape with ratchet (3).
2,, it is characterized in that ratchet (3) part on the spanner alive (1) can be semicircle or 1/4 circle setting by the described free return stroke formula of claim 1 adjustable wrench.
