The first embodiment is as follows:

referring to fig. 1-6, the present invention provides a technical solution: the utility model provides an instrument grinding special type electricity main shaft, including electricity main shaft 1, be provided with hexagonal bolt 10 on the electricity main shaft 1, slide 8 has been seted up on the surface of apron 6, slide 8's inside sliding connection has gag lever post 7, the one end fixed mounting that apron 6 was kept away from to gag lever post 7 has connecting plate 5, gag lever post 7 extends to slide 8 inside one end fixed mounting has smooth ball 15, smooth ball 15 is at slide 8's inside sliding connection, slide 8's shape is circular, smooth ball 15's shape is spherical.

When gag lever post 7 outwards removed, make smooth ball 15 slide in slide 8's inside, because smooth ball 15's shape is spherical, slide 8's shape is circular, and then be convenient for restrict gag lever post 7 and connecting plate 5, and then prevent that connecting plate 5 and gag lever post 7 and slide 8's inside from breaking away from, the stability of device use has been guaranteed, reduce the probability that connecting plate 5 and device break away from, the phenomenon of damage appears in the reduction device, the smooth butt joint of hexagonal pole 9 and hexagonal bolt 10 of being convenient for, improve the precision of butt joint.

The inside fixed mounting of slide 8 has spring 2, and spring 2 is close to one end and the smooth ball 15 fixed connection of smooth ball 15, and the inside of connecting plate 5 is rotated and is connected with dwang 4, and the one end fixed mounting that dwang 4 is close to six prismatic bolt 10 has six prismatic pole 9, and six prismatic pole 9 is identical with the recess on the six prismatic bolt 10, and six prismatic pole 9 is located six prismatic bolt 10's inside.

When the hexagonal bolt 10 is disassembled, the connecting plate 5 is pulled outwards, and then the rotating rod 4 is driven to move outwards, so that the limiting rod 7 and the sliding ball 15 move outwards, the spring 2 is further stretched, the hexagonal rod 9 and the hexagonal bolt 10 are further separated from each other and are further not limited by the hexagonal rod 9, when the hexagonal bolt 10 needs to be limited, the connecting plate 5 is reset through the tensile force of the spring 2, so that the connecting plate 5 is reset, the hexagonal rod 9 is clamped into the hexagonal bolt 10, the limitation on the hexagonal bolt 10 is further completed, the hexagonal bolt 10 is further conveniently limited, the hexagonal bolt 10 is further prevented from being reversed when the hexagonal bolt 10 is subjected to long-time external vibration, the fixing effect of the hexagonal bolt 10 on the cover plate 6 is improved, and the stability of the use of the device is ensured to the maximum extent, the phenomenon of reduction device damage appears, reduces 6 phenomena that drop that appear in apron, reduces the number of times that the workman maintained.

Example two;

referring to fig. 1-6, on the basis of the first embodiment, a clamping rod 12 is slidably connected inside the connecting plate 5, a clamping groove 11 is formed in the surface of the rotating rod 4, the clamping grooves 11 are equidistantly formed in the surface of the rotating rod 4, one end of the clamping rod 12 close to the clamping groove 11 is clamped inside the clamping groove 11, a placing groove 13 is formed inside the connecting plate 5, a return spring 14 is movably sleeved on the surface of the clamping rod 12, one end of the return spring 14 is fixedly connected with the inside of the placing groove 13, the other end of the return spring 14 is fixedly connected with the surface of the clamping rod 12, and a pull ring 3 is fixedly mounted at one end of the clamping rod 12 extending to the outside of the connecting plate 5.

When six edges on the hexagonal rod 9 are not matched with the hexagonal grooves on the hexagonal bolt 10, the pull ring 3 is pulled outwards, so that the clamping rod 12 moves outwards, the return spring 14 is extruded, the clamping rod 12 is separated from the interior of the clamping groove 11, the rotating rod 4 is rotated, the rotating rod 4 rotates in the connecting plate 5, so that the hexagonal rod 9 rotates, when the hexagonal rod 9 is matched with the hexagonal grooves on the hexagonal bolt 10, the pull ring 3 is not pulled, so that the pull ring 3 and the clamping rod 12 are reset through the elastic force of the return spring 14, because the clamping grooves 11 are equidistantly arranged on the surface of the rotating rod 4, and are arranged more densely, so that the clamping rod 12 is clamped into the interior of another clamping groove 11, so that the angle of the hexagonal rod 9 is convenient to adjust, the hexagonal rod 9 is accurately butted with the hexagonal bolt 10, and the limiting effect on the hexagonal bolt 10 is improved, the smooth operation of the device is ensured.

The working principle is as follows:

when the hexagonal bolt 10 is disassembled, the connecting plate 5 is pulled outwards, and then the rotating rod 4 is driven to move outwards, so that the limiting rod 7 and the sliding ball 15 move outwards, the spring 2 is stretched, the hexagonal rod 9 and the hexagonal bolt 10 are separated from being fixed, the hexagonal rod 9 is not limited to the hexagonal bolt 10, when the hexagonal bolt 10 needs to be limited, the connecting plate 5 is reset through the tensile force of the spring 2, the connecting plate 5 is reset, the hexagonal rod 9 is clamped into the hexagonal bolt 10, the limitation on the hexagonal bolt 10 is completed, the hexagonal bolt 10 is conveniently limited, and the hexagonal bolt 10 is prevented from being reversed when being subjected to external long-time vibration.

When six arriss on hexagonal pole 9 and hexagonal groove on hexagonal bolt 10 are not anastomotic, outside pulling pull ring 3, and then make kelly 12 outwards remove, make reset spring 14 extruded, then make kelly 12 break away from fixedly with the inside of draw-in groove 11, and then rotate dwang 4, make dwang 4 rotate in the inside of connecting plate 5, and then make hexagonal pole 9 rotate, when hexagonal groove on hexagonal pole 9 and hexagonal bolt 10 is anastomotic, do not at pulling pull ring 3, make pull ring 3 and kelly 12 reset through reset spring 14's spring action, because a plurality of draw-in grooves 11 are the equidistance on the surface of dwang 4 and set up, set up simultaneously denser, and then make kelly 12 block into the inside of another draw-in groove 11, and then be convenient for adjust the angle of hexagonal pole 9.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
