Description
Technical field
The utility model relates to a kind of operation spanner.
Background technology
In prior art, the operating handle of switch cubicle is divided into mobile jib with contact and action bars that can 180 ° of rotations.In use, need in advance operating handle is adjusted to appropriate location, then the contact of mobile jib head inserted to the gathering hole being arranged on switch cubicle, utilize the action bars of lever principle pulling handle realize switch cubicle point, closing operation.But, actual carry out switch cubicle point, when closing operation, need to counterclockwise or turn clockwise operating handle to realize operation object, because action bars maximum can only be carried out 180 ° of angle rotations, and be subject to the impact of the factor such as switch cubicle space and operator's strength size, working strength is larger, if angle is bad in operation, can strengthen operation easier, even need contact to extract and readjust position from the gathering hole of switch cubicle, this can bring very big inconvenience to operation undoubtedly.
Utility model content
The purpose of this utility model is to provide the ratchet type operation spanner that a kind of action bars can rotate freely.
For achieving the above object, the utility model adopts following technical scheme:
A kind of operation spanner, comprise mobile jib, action bars and plectrum, one end of mobile jib is provided with contact, other end outer surface is evenly provided with projection, curved and the plectrum of plectrum is provided with the first through hole, the end, one end of action bars has installing hole, this end that mobile jib is provided with projection is arranged in described installing hole, the second through hole that this end that action bars is connected with mobile jib has pin-and-hole and matches with plectrum, plectrum is arranged in the second through hole, steady pin is through the first through hole on plectrum and the pin-and-hole on action bars, and one end of plectrum is stretched in installing hole.
Action bars is enclosed within mobile jib outer surface by installing hole, action bars can carry out taking mobile jib as axle 360 ° of rotations, in addition, by regulating plectrum that plectrum is stuck between the projection on mobile jib, while being now rotated in the forward action bars, action bars and mobile jib generation rotating in same direction, when being rotated in the forward after certain angle, when being subject to the impact in switch cubicle space and can not continuing to be rotated in the forward action bars, now, adjust plectrum, make claw on plectrum and protruding separation on mobile jib, mobile jib and action bars relatively rotate, then counter-rotate action bars, after adjusting angle, by adjusting plectrum, mobile jib and action bars are rotated simultaneously again, thereby when realizing positive and negative rotation action bars, drive mobile jib rotate and do not need action bars to take off correction again towards a direction, effectively evade in operating process because adjust incorrect, need take off the problem that action bars is proofreaded again.
As improvement of the present utility model, on plectrum, be also provided with arc groove, on action bars, also have a blind hole, a spring is set in blind hole, one end of spring contacts with the cecum of blind hole, the other end is installed a steel ball, and described steel ball is stuck in the arc groove of plectrum.
The end of engagement that plectrum comprises and projection engages and the struck side not contacting with projection, plectrum is provided with two arc grooves, and in the time that engage with projection one end of plectrum, one end of steel ball is pressed forward by spring, and the other end is stuck in the arc groove on plectrum; In the time that needs are adjusted plectrum, press the struck side of plectrum downwards with hand, plectrum can rotate in the second through hole so, the end of engagement of plectrum departs from projection, Compress Spring when plectrum rotates, the steel ball of spring at front end slides on plectrum, in the time sliding into another arc groove of plectrum, spring heads into steel ball in arc groove, and the position of plectrum is locked.Thereby can fix the position of plectrum.
As improvement of the present utility model, this end that plectrum stretches into installing hole is provided with latch.
It is more firm that latch and protruding cooperation can make plectrum and mobile jib engage, thereby can ensure that mobile jib and action bars synchronously rotate, and improves rotating effect.
Further improve as of the present utility model, described installing hole is circular hole.The difformity of installing hole can corresponding different mobile jib, makes the engaging of action bars and mobile jib more firm.
In sum, the beneficial effects of the utility model are that the convenient direction of adjusting action bars, has reduced real work amount, has improved rotating effect.

Fig. 2 is the utility model structural representation.
Fig. 3 is that the utility model plectrum is stuck in the schematic diagram between projection.
Detailed description of the invention
As shown in Figure 2, a kind of operation spanner, comprise mobile jib 1, action bars 2 and plectrum 4, one end of mobile jib 1 is provided with contact, other end outer surface is evenly provided with projection 3, the end, one end of action bars 2 has installing hole, this end that mobile jib 1 is provided with projection 3 is arranged in described installing hole, action bars 2 has circular arc through hole and pin-and-hole near this end of installing hole, the plectrum 4 that has through hole is arranged in circular arc through hole, steady pin is through the through hole on plectrum 4 and the pin-and-hole on action bars 2, plectrum 4 can rotate around steady pin in circular arc through hole and one end of plectrum 4 can be stretched in installing hole and be fastened between the projection 3 on mobile jib 1.
As shown in Figure 3, be also provided with arc groove on plectrum 4, also have a blind hole on action bars 2, a spring 5 is set in blind hole, one end of spring 5 contacts with the cecum of blind hole, the other end is installed a steel ball 6, and described steel ball 6 is stuck in the arc groove of plectrum 4.
When use, first the contact of mobile jib is inserted in the gathering hole of switch cubicle, be in place; According to need of work, operate clockwise or operation counterclockwise again.Be inconvenient to operate or operate while relatively requiring great effort when being subject to affecting of inside switch cabinet space, the direction of rotating by plectrum control, that is: make plectrum end of engagement depart from the projection on mobile jib, and steel ball is stuck in the arc groove of plectrum with fixing operation bar, counter-rotate again action bars, make action bars and mobile jib generation relative motion, now mobile jib is motionless; When reverse rotation certain angle is applicable to operation, then regulate plectrum, the end of engagement of plectrum is engaged with the projection on mobile jib, the steel ball that plectrum is stuck in its arc groove is simultaneously fixed; Now, when rotation action bars, action bars drives mobile jib to rotate simultaneously, thereby realizes the object of operation, and does not need mobile jib to take off again and proofread and correct from switch cubicle.
The utility model improves on traditional operating handle, ratchet device has been installed, make action bars in traditional handicraft can only 180 ° with respect to mobile jib rotation innovation for can 360 ° of rotations, the direction of convenient adjustment action bars, again proofread and correct and do not need action bars to take off from mobile jib, effectively avoid the drawback because of inside switch cabinet limited space impact operation simultaneously, more convenient to use, quick.
