[0024] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of a cemented carbide pressure-resistant impact cutter of the utility model in conjunction with the accompanying drawings.

[0025] like Figure 1-5As shown, a cemented carbide pressure-resistant impact tool of the utility model comprises a blade body 1, a blade blade 2 is fixedly connected to the surface of the blade body 1, a scabbard 6 is sleeved on the surface of the blade body 1, an external threaded rod 8 is welded on the surface of the blade body 1, a slide groove 7 is provided on the surface of the scabbard 6, the external threaded rod 8 is located inside the slide groove 7, and by providing the slide groove 7, the slide groove 7 can be utilized to provide a moving effect for the scabbard 6, which is very convenient to use, an extrusion turntable 9 is installed on the surface of the external threaded rod 8, and the bottom of the extrusion turntable 9 is attached to the surface of the scabbard 6, and the blade 2 is located inside the scabbard 6, and by installing the scabbard 6, the blade 2 can be hidden inside the scabbard 6 so that the blade 2 will not be exposed to the outside, and the blade 2 can be protected at this time so that the blade 2 will not be worn, and the protective performance is strong when used.

[0026] A baffle frame 4 is welded on the surface of the blade body 1, and anti-slip strips 5 are welded on the side of the baffle frame 4. The anti-slip strips 5 are evenly distributed. A slot 3 is provided on the surface of the blade body 1. By installing the anti-slip strips 5, when the blade body 1 is installed on the handle, the anti-slip strips 5 can be used to increase the friction between the handle and the blade body 1, so that the stability is stronger during use.

[0027] A rotating shaft 11 is welded to the side of the scabbard 6, a stop bar 12 is welded to the surface of the rotating shaft 11, a soft strip 13 is bonded to the side of the stop bar 12, and the soft strip 13 is located between the blade 2 and the stop bar 12. By installing the soft strip 13, the blade 2 can be further protected by the soft strip 13, so that the blade 2 will not be bumped, and the protection is strong when in use.

[0028] The surface of the scabbard 6 is fixedly connected to the fixing seat 14, and the other end of the fixing seat 14 is welded with a shift plate 15. By installing the shift plate 15, when the scabbard 6 needs to be moved, the shift plate 15 can be used as a force point to move the scabbard 6, which is very convenient to use.

[0029] A retaining ring 10 is welded to the other end of the externally threaded rod 8. The bottom of the retaining ring 10 is attached to the top of the extrusion turntable 9. The retaining ring 10 is symmetrically distributed. By installing the retaining ring 10, the retaining ring 10 can provide a limiting effect for the extrusion turntable 9, so that the extrusion turntable 9 will not separate from the externally threaded rod 8, which is very convenient to use.

[0030] The external threaded rods 8 are symmetrically distributed, and the slide grooves 7 are symmetrically distributed. Through the installation of the external threaded rods 8 and the distribution of the slide grooves 7, when the scabbard 6 is moved, the scabbard 6 will not shake left and right, and the stability is strong during use.

[0031] The working principle of the cemented carbide pressure-resistant impact tool is as follows: when using the cemented carbide pressure-resistant impact tool, the scabbard 6 should be moved to a suitable position first. At this time, the extrusion turntable 9 is rotated first, and moved upward under the action of the external threaded rod 8 until it leaves the surface of the scabbard 6, and the gear bar 12 is moved away through the rotating shaft 11, and then the scabbard 6 can be moved. When moving the scabbard 6, the dial plate 15 can be used as a force point until the scabbard 6 is moved. When the scabbard 6 is moved to a suitable position, the extrusion turntable 9 is rotated again until the extrusion turntable 9 and the scabbard are 6 surfaces fit each other, thereby increasing the friction between the blade 1 and the scabbard 6, and fixing the scabbard 6, and then the carbide pressure-resistant impact tool can be used. After use, the scabbard 6 is moved back to its original position, and the gear bar 12 is rotated by the rotating shaft 11 until the soft strip 13 is embedded in the scabbard 6. At this time, the scabbard 6 and the gear bar 12 can be used to hide the blade 2 in the scabbard 6, so that the blade 2 will not be exposed to the outside. At this time, the blade 2 can be protected so that the blade 2 will not be worn, and the protection is strong when used.

[0032] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
