Problems solved by technology

[0002] The bolt caps (nuts) widely used in industrial production are exposed to high temperature or corrosive environments, some are rusted to death, and some are damaged due to bumping. In short, it is very difficult to disassemble the nuts if there is a problem. Yes, the previous practice is to use (gas) welding to cut off the nuts and bolts together. However, in some special working conditions, sometimes it is strictly forbidden to use fire (electricity) welding operations, such as coal powder bunkers and oil pipelines in power plants. In high-pressure and high-temperature pipelines, etc., it is even more difficult to replace nuts and bolts
After the common nut cutter cuts the nut, it is still difficult to remove it from the bolt due to the perennial corrosion of the nut, and it usually needs to be hit with a hammer to fall off.

Embodiment 1

[0029] refer to figure 1 and figure 2 , is the first embodiment of the present invention. This embodiment provides a portable multifunctional nut cutter. The portable multifunctional nut cutter includes a fixing assembly 100 and a cutting assembly 200. The rusted The nuts are fixed and clamped, and the rusted nuts can be cut through the cutting assembly 200 and the nuts can be opened for easy removal after cutting.

[0030] Specifically, the fixing assembly 100 includes a fixing collar 101 and a handle 102 arranged at one end of the fixing collar 101. The fixing collar is used for fixing and clamping the rusted nut, and the handle 102 is used for connecting an external power device, such as a manual or Motorized, also used for fixing of internal breaker components.

[0031] Preferably, the shredding assembly 200 includes a moving part 201 arranged inside the handle 102, a spreading part 202 arranged inside the moving part 201, and locking parts 203 at both ends of the movin...

Embodiment 2

[0034] refer to Figure 1 to Figure 7 , is the second embodiment of the present invention, which is based on the previous embodiment.

[0035] Specifically, the handle 102 also includes a first moving groove 102a provided on its surface, the first moving groove 102a is used for moving and extending the inner structure, and the user controls the inner structure from the outside.

[0036] Preferably, the moving part 201 includes a screw rod 201a arranged inside one end of the handle 102. The screw rod 201a is threadedly engaged with the handle 102. The entry and exit of the screw rod 201a inside the handle 102 is an important travel mechanism for cutting, and the power source can be manually rotated with a wrench. The screw rod 201a completes the axial movement of the screw rod 201a, and electric equipment such as a pistol drill can also be used to rotate the screw rod 201a. There are various ways of use and high selectivity.

[0037] Preferably, the moving part 201 further inc...

Abstract

The invention discloses a portable multi-function nut splitter. The portable multi-function nut splitter comprises a fixing component and a splitting component, wherein the fixing component comprises a retaining collar and a handle arranged at one end of the retaining collar; and the splitting component comprises a moving part arranged in the handle, an opening piece arranged in the moving part and locking pieces arranged at the ends of the two sides of the moving part. Through the arrangement of the fixing component and the splitting component, the device can easily take down a rusted nut without the help of other tools after splitting the rusted nut, can be operated manually or electrically, and is diversified in function, convenient, practical, small, exquisite and portable.

Description

technical field [0001] The invention relates to the technical field of nut shredding, in particular to a portable multifunctional nut shredder. Background technique [0002] The bolt caps (nuts) widely used in industrial production are exposed to high temperature or corrosive environments, some are rusted to death, and some are damaged due to bumping. In short, it is very difficult to disassemble the nuts if there is a problem. Yes, the previous practice is to use (gas) welding to cut off the nuts and bolts together. However, in some special working conditions, sometimes it is strictly forbidden to use fire (electricity) welding operations, such as coal powder bunkers and oil pipelines in power plants. In places such as high-pressure and high-temperature pipelines, it is even more helpless to replace nuts and bolts. After the common nut cutter cuts off the nut, it is still difficult to remove it from the bolt due to the perennial corrosion of the nut, and it usually needs t...
