Abstract
The utility model discloses a step ratchet block opening transcend idle spanner. An upper wrench opening of utility model is provided with a concave angle of 120 DEG, and a lower wrench opening of the utility model is provided with a ratchet, wherein, the ratchet can be slid from left to right; the ratchet is provided with a high step and a low step. Thereby, the process in overtaking and tightening can be completed. Besides, the utility model has the advantage of high intensity, and the reverse square angle is only 30 DEG.
Description
The stiff hand of a kind of step sour jujube of the present invention piece formula is particularly a kind of have transcendent function fall corner be 30 ° stiff hand be fit to screw (pine) nut.
The stiff hand of opening is a kind of instrument of extensive use in mechanical industry, but the nut that exists certainly that the side of moving generally screws (pine) need change number formulary time, so extremely inconveniently need to improve.
The opening that the purpose of this invention is to provide the angle of making the return trip empty and be 30 ° surmounts fork spanner
The present invention realizes (seeing accompanying drawing 1) like this
This wrench is made up of plate body (1) step sour jujube piece (7) two large divisions, by bearing pin (8) two bodies is connected together.The upper plate mouth (2) of plate body (1) is gone up system 120 ° of re-entrant angles (3) step sour jujube pieces (7) upper end and is shaped on the low step (11) of high step (9), the lower end is shaped on slotted hole (12), the torque spring (6) fixing by bearing pin (10) forces sour jujube piece (7) to slide to the inboard of plate mouth, and the length of slotted hole (12) has determined the full-size that the sour jujube piece horizontally slips.During operation when the dextrorotation handle, nut can screw nut because of the restriction of the physical dimension that is subjected to upper plate mouth (2) and high step (9), when handle is revolved counterclockwise in the need side of changing, the reaction strength of nut is extrapolated step sour jujube piece (7) Xiang Bankou, the last drift angle of nut can enter in the re-entrant angle (3) when handle revolves 30 ° counterclockwise, this moment, step sour jujube piece reentered the plate mouth because of the effect sour jujube piece (7) of torque spring (6), and the restriction of the physical dimension of the following drift angle of nut and low step (11) just can to nut counterclockwise screwed power, but like this repeatable operation just complete operation for several times.
The present invention has following good effect:
1, the sour jujube piece only bears pressure, so the intensity high technology is good.
2, there is the transcendent function side of the changing angle of making the return trip empty only to be 30 °.
The invention will be further described below in conjunction with accompanying drawing
Plate body (1) is connected by bearing pin (6) with step sour jujube piece (7), be shaped on the upper plate mouth (2) that 120 ° of re-entrant angles (3) sour jujube pieces (7) upper ends is shaped on high and low step (9), (11) lower end is shaped on slotted hole (12), the physical dimension when dextrorotation handle (4) between plate mouth (2) and high step (9) can restrict the both sides up and down of nut or re-entrant angle (3) thereby otherwise can and finish the side of changing restraining force disappearance outside the sour jujube piece head board mouth with two jiaos of nuts when screwing nut and revolving handle (4) counterclockwise up and down of the restriction of the physical dimension between low step nut.
Claims (1)
- A kind of step sour jujube piece opening surmounts stiff hand and is made up of plate body (1) step sour jujube piece (7) and it is characterized in that:1, plate body (1) and step sour jujube piece (7) are connected by bearing pin (8);2, upper plate mouth (2) is shaped on 120 ° of re-entrant angles (3);3, step sour jujube piece upper end is shaped on the low step (11) of high step (9), and the lower end is shaped on slotted hole (12);4, be fixed with torque spring (6) by bearing pin (10).
