Abstract
The utility model discloses a spanner, including the main part, the handle is stretched out to the rear end of main part, and the front end then is equipped with fixed spanner and spout, but the movable mounting of tooth portion of the rear end of activity spanner cooperate in the spout and with the worm wheel pole installed in the main part, rotate the worm wheel pole and can remove by drive activity spanner relatively fixed spanner, movable spanner open and to have the holding chamber, have spring and removable pin in the holding chamber, the left end of spring offsets with the left end wall in holding chamber, the right -hand member then supports the right -hand member wall in the holding chamber with removable pin elasticity, the right -hand member of removable pin has the stop pin of the right -hand member wall that stretches out the holding chamber, the stop pin can block in the card hole of abnormal -shaped nut lateral wall. The utility model is simple in operation, it is convenient, efficient to at the dismouting in -process, cylindrical abnormal -shaped nut's surface is the atress basically not, and consequently, the dismouting in -process can not cause any harm to cylindrical abnormal -shaped nut's surface, can guarantee abnormal -shaped nut's outward appearance aesthetic feeling, and life.
Description
Technical field
The utility model relates to a kind of spanner, particularly a kind of spanner that also can be used for the columniform profile nut of dismounting.
Background technology
Nut coordinates with bolt or screw rod the part played the role of fastening, and is the element applied in manufacturing machine and daily life widely, nut generally have standard nut and profile nut (some irregular, grotesque nuts) point.Wherein, dismounting and the assembling of standard nut are undertaken by traditional spanner, and operation is very easy, and profile nut, then cannot be undertaken dismantling and assembling by traditional spanner, as shown in Figure 1, a kind of cylindrical profile nut 10, its outer wall is cylindrical, outer wall has annular groove 110, two hole clippings 110 are diametrically provided with in annular groove 110, in prior art, dismantle and assemble this profile nut, usually the cylindrical outer wall of profile nut only " is bitten " by pliers, firmly rotate pliers, thus make it absent-mindedness or tighten, although it can realize dismounting and the assembly manipulation of this type of profile nut substantially, but exist following not enough: 1, in operation, the circular outer wall of pliers and profile nut easily skids, dismounting and efficiency of assembling low, 2, pliers can bite the surface of profile nut, and when particularly skidding, the degree of profile nut surface damage is larger, finally causes the injurious surface mark of this type of profile nut innumerable, not only affects the outward appearance of cylindrical profile nut, also can reduce its service life.
Summary of the invention
The purpose of this utility model be to provide a kind of also can the spanner of for convenience detach and above-mentioned columniform profile nut of assembling, and ensure that the surface of this cylindrical profile nut is injury-free.
A kind of spanner described in the utility model, comprise main body, handle is stretched out in the rear end of main body, front end is then provided with fixing spanner and chute, the teeth portion of the rear end of movable jaw is movable to be installed in chute and to match with the worm gear pole be installed in main body, rotating worm gear pole can drive movable jaw to move relative to fixing spanner, described movable jaw has accommodating cavity, spring and removable pin is had in accommodating cavity, the left end of spring and the left end wall of accommodating cavity offset, removable pin elasticity is then butted on the right-hand member wall of accommodating cavity by right-hand member, the right-hand member of removable pin has the stop pin of the right-hand member wall stretching out accommodating cavity, stop pin can snap in the hole clipping of profile nut sidewall.
Spanner described in the utility model, in the process of dismounting or assembling profile nut, first will move movable jaw by rotation worm gear pole, be greater than the external diameter of cylindrical profile nut with the spacing making movable jaw move to stop pin on it and fixing spanner, then, spanner is moved to cylindrical profile nut is stuck between fixing spanner and movable wrench, and then, after relative with the annular groove of cylindrical profile nut sidewall to its stop pin for spanner fine setting, rotate backward worm gear pole, reduce movable jaw extremely to fit mutually with the external diameter of cylindrical profile nut with the spacing of fixing spanner, stop pin and annular groove are offseted and partly pushes back accommodating cavity, then, rotary spanner, stop pin is slided along the annular groove of cylindrical profile nut outer wall, when stop pin slides into relative with hole clipping, stop pin 41 is inserted in hole clipping under the effect of spring 3 elastic force, spanner and circular profile nut are locked, now, hold pinch bar and rotate, cylindrical profile nut then can under the drive of stop pin, rotate with spanner, thus complete dismounting or the assembling of cylindrical profile nut.It is simple, convenient, and efficiency is high, and in disassembly process, the outer surface of cylindrical profile nut does not stress substantially, therefore, can not cause any infringement in disassembly process to the outer surface of cylindrical profile nut, the aesthetic appearance of profile nut can be ensured, and service life.

Fig. 2 is structural representation of the present utility model.
Fig. 3 is the enlarged detail of the part A of Fig. 2.
Fig. 4 is the schematic diagram after the utility model tears a removable pin and spring open.
Detailed description of the invention
As shown in Figures 2 to 4, described spanner, comprise main body 1, handle 11 is stretched out in the rear end of main body 1, front end is then provided with fixing spanner 12 and chute 13, the teeth portion 21 of the rear end of movable jaw 2 is movable to be installed in chute 13 and to match with the worm gear pole 5 be installed in main body 1, rotating worm gear pole 5 can drive movable jaw 2 to move relative to fixing spanner 12, described movable jaw 2 has accommodating cavity 23, spring 3 and removable pin 4 is had in accommodating cavity 23, the left end of spring 3 and the left end wall 22 of accommodating cavity 23 offset, removable pin 4 elasticity is then butted on the right-hand member wall of accommodating cavity 23 by right-hand member, the right-hand member of removable pin 4 has the stop pin 41 of the right-hand member wall stretching out accommodating cavity 23, stop pin 41 can snap in the hole clipping of profile nut sidewall.In the process of dismounting or component location guide cylindricality profile nut, first will move movable jaw 2 by rotating worm gear pole 5, being greater than the external diameter of cylindrical profile nut with the spacing making movable jaw 2 move to stop pin on it 41 and fixing spanner 12; Then, spanner is moved to and cylindrical profile nut is stuck between fixing spanner 12 and movable wrench 2; And then, after relative with the annular groove of cylindrical profile nut sidewall to its stop pin 41 for spanner fine setting, rotate backward worm gear pole, reduce movable jaw 2 extremely to fit mutually with the external diameter of cylindrical profile nut with the spacing of fixing spanner 12, stop pin 41 and annular groove are offseted and partly pushes back accommodating cavity 23, then, rotary spanner, makes stop pin 41 slide along the annular groove of cylindrical profile nut outer wall; When stop pin 41 slides into relative with hole clipping, stop pin 41 is inserted in hole clipping under the effect of spring 3 elastic force, spanner and circular profile nut are locked, now, hold pinch bar and rotate, cylindrical profile nut then under the drive of stop pin 41, can rotate with spanner, thus completes dismounting or the assembling of cylindrical profile nut.It is simple, convenient, and efficiency is high, and in disassembly process, the outer surface of cylindrical profile nut does not stress substantially, therefore, can not cause any infringement in disassembly process to the outer surface of cylindrical profile nut, the aesthetic appearance of profile nut can be ensured, and service life.
Described stop pin and removable pin can be integrated structures, also can be welded on removable pin.
