The utility model provides a concrete embodiment 1 of broken nut instrument of tearing open:

as shown in fig. 1 and 2, the utility model provides a broken dismouting of nut device includes sleeve 2, and the sleeve extends along the fore-and-aft direction, and its front end an organic whole is provided with pullover 3, and pullover 3 is the loop configuration for the suit is on waiting to break the nut of tearing open.

The sleeve 2 is provided with a cutter 4 in a guiding and moving mode along the front-back direction, the front end of the cutter 4 is a cutter head, the rear end of the cutter 4 is used for being pushed by a corresponding pushing bolt 1 to move forwards, and a nut is cut by the cutter head to realize breaking and dismantling.

The cutting knife 4 is provided with a guide groove extending along the front-back direction, correspondingly, the sleeve 1 is spirally provided with a guide screw 5, the guide screw 5 extends along the radial direction of the sleeve and is in insertion fit with the guide groove as a guide part, and therefore the cutting knife is guided to move front and back.

A jacking bolt 1 is further assembled in the sleeve 2, the jacking bolt 1 is positioned behind the cutter, and the jacking bolt 1 is spirally assembled with the sleeve 2. The rear end of the cutter 4 is rotatably assembled with the ejector bolt 1, and the cutter can be driven to advance and retreat when the ejector bolt rotates to advance and retreat.

Specifically, an insertion section is convexly arranged at the rear end of the cutter 4, an annular groove 41 is arranged on the insertion section, an insertion groove is arranged at the front end of the pushing bolt 1 and serves as an adaptive insertion section for the insertion section to be matched in an insertion manner, an annular clamping groove is arranged in the insertion groove, a clamping spring 6 is arranged on the annular groove 41 during assembly, the clamping spring is a hole-used clamping spring and can rotate around the circumferential direction of the insertion section, and after the hole-used clamping spring enters the insertion groove, the clamping spring is correspondingly matched with the annular clamping groove in a clamping manner, so that the insertion section can be placed to be separated from the insertion groove. Because the connection of the cutter and the pushing bolt is realized by the clamp spring, the cutter and the pushing bolt are effectively prevented from being separated under the condition of ensuring that the cutter and the pushing bolt can rotate relatively. In this embodiment, the insertion section uses as the grafting section of cutter, and the slot uses as the adaptation grafting section of top bolt, and then under the effect of jump ring, guarantees the rotation assembly between them.

In addition, the cross section of the sleeve 2 is rectangular, so that the sleeve 2 is relatively small in size and relatively high in strength under the condition of ensuring the strength, and the handheld operation is also facilitated.

Moreover, for convenient operation, the head of the jacking bolt 1 is provided with a rotation stopping matching structure, so that an operator can conveniently drive the jacking bolt 1 to rotate by using tools such as a wrench and the like.

When the nut is broken and torn by the breaking-in tool provided by the embodiment, the sleeve head 3 is sleeved on the nut to be dismantled, then the pushing bolt 1 is rotated to push the cutter 4 to move forwards, and the cutter 4 applies acting force to the nut to cut off the nut, so that the purpose of breaking-in is achieved. When more nuts need to be broken and disassembled, the jacking bolt 1 can be rotated anticlockwise, the jacking bolt 1 drives the cutter 4 to return to the original position through the adaptive inserting device, and then the initial step is repeated. The adaptive connecting device is used for driving the cutter 4 to move along with the ejector bolt when the ejector bolt 1 rotates anticlockwise so as to finish the purpose of retracting the cutter.

In the broken nut instrument of tearing open that this embodiment provided, through the top pushing bolt drive cutter prospect, can realize convenient, quick destroy and demolish the nut of rustting and smooth silk. Has the advantages of convenient operation, time saving, labor saving and the like. In addition, the cutter and the pushing bolt are assembled together in a rotating mode, the cutter can conveniently move forwards and backwards through the pushing bolt, operation is convenient, and independent cutter moving operation is not needed.

The utility model provides a concrete embodiment 2 of broken nut instrument of tearing open:

the difference from example 1 is mainly that: in embodiment 1, the cutter and the pushing bolt are rotatably assembled through the insertion section, the slot and the clamp spring. In this embodiment, the cutter and the jack bolt may be rotatably assembled by a bearing, wherein the bearing may be selected from a rolling bearing, a sliding bearing or a thrust bearing.

The rolling bearing or the sliding bearing can be sleeved between the insertion section and the slot, so that the rotary assembly of the cutter and the pushing bolt is realized.

The thrust bearing comprises two end plates and a middle rolling body, one end plate is fixedly connected with the rear end of the cutter, the other end plate is fixedly connected with the front end of the pushing bolt, and the rotary assembly of the cutter and the pushing bolt can be realized.

Of course, in other embodiments, the front end of the ejector bolt may be provided with an insertion section, the rear end of the cutter may be provided with an adaptive slot, and the cutter and the ejector bolt may be rotatably assembled by providing a corresponding bearing therebetween.

The utility model provides a concrete embodiment 3 of broken nut instrument of tearing open:

the difference from example 1 is mainly that: in embodiment 1, the ferrule and the sleeve are integrally provided. In this embodiment, the sleeve head and the sleeve are separately arranged, and can be fixedly assembled through threaded connection or a clamping structure.

The utility model provides a concrete embodiment 4 of broken nut instrument of tearing open:

the difference from example 1 is mainly that: in embodiment 1, the guide screw serves as a guide to guide the cutting knife to move in the front-rear direction. In this embodiment, the guide part also can adopt guide pin, and guide pin fixes in sleeve and pullover junction, and it can to guarantee that guide pin and the guide way on the tool bit are the cooperation of leading.

The utility model provides a concrete embodiment 5 of broken nut instrument of tearing open:

the difference from example 1 is mainly that: in the embodiment 1, the inner hole of the sleeve head is a round hole. In this embodiment, the sleeve head may also be a hexagonal hole.
