Description

A handle having chisel}

The present invention relates to a tablet having a handle having a removable assembly function, and more particularly, by forming a fastening hole in the tablet and detachably installing a support bar having a fitting protrusion in the fastening hole, the vibration transmitted when the tablet is hit. The present invention relates to a tablet equipped with a handle having a detachable assembly function, which can be used to cushion the wear and replace a worn definition, thereby recycling and reducing maintenance costs.

Generally, the stone, or stone, used in buildings is used to make a smooth surface like mirror surface, but it is also used to make the surface of stone artificially bumpy for natural beauty. As a method of roughly processing, for example, a method of impacting the surface of the stone using a pointed extension to partially extrude it is used.

The pointed extension is a tablet made of a metal material, the stone can be processed by hammering the tablet with a hammer, and the tablet is erected at right angles from the loading surface and then hit.

However, since the conventional tablets are erected by the worker after holding the tablets, the hammers strike the hand held by the hammer during the blow, causing serious injury to the worker, and the vibration of the gripped hand is transmitted, resulting in repeated impacts. There was a problem that the worker feels tired.

Recently, in order to solve the above problems, by welding a metal bar to the tablet and hitting the tablet while holding the bar, the worker is less likely to be injured. Since both tablets and bars must be disposed of, there is a problem of excessive replacement costs.

The present invention is devised to solve the above problems, an object of the present invention is to form a fastening hole in the well and to detachably install a support bar having a fitting protrusion in the fastening hole, to cushion the vibration transmitted when hitting the well In addition, the purpose is to provide a tablet with a handle having a removable assembly function that can be recycled and reduced maintenance costs as well as replace the worn definition.

The present invention is a stone processing tablet having a pointed portion at one end, the fastening hole is formed in the center to penetrate through the central portion, the end of the support bar is fastened to the fastening hole detachably, one end of the support bar A fitting protrusion having a screw portion is formed on the outer circumference so as to penetrate through, and a fastening groove is formed correspondingly to a distal end side to fix the support bar with tongs, and at the end of the fitting protrusion protruding through the coupling hole. A nut is fastened so that the support bar is fixed to the well, and a bushing member made of synthetic resin is further fastened to the fastening hole, and the fitting protrusion of the support bar is fastened through the bushing member to be delivered when the tablet is hit. The vibration is buffered by the bushing member to be transmitted to the support bar, the fastening hole facing each other on the outer periphery The guide groove is formed, the outer surface of the bushing member is provided with a guide projection to be fitted into the guide groove, a pair of fixing grooves are formed on the inner circumference of the bushing member, the outer surface of the fitting protrusion in the fixing groove A fixing protrusion is formed to be fitted, and the bushing member and the fitting protrusion are prevented from being rotated in the fastening hole by vibration when the hitting member is hit.

Figure 2 is a perspective view showing a tablet provided with a handle having a removable assembly function according to the present invention.
Figure 3 is a view showing another embodiment provided with a handle having a removable assembly function according to the present invention.
Figure 4 is a view showing another embodiment provided with a handle having a removable assembly function according to the present invention.

Hereinafter, with reference to the accompanying drawings will be described with reference to the accompanying drawings a preferred embodiment with a handle having a removable assembly function according to the present invention. In this process, the thicknesses of the lines and the sizes of the components shown in the drawings may be exaggerated for clarity and convenience of explanation. In addition, the terms described below are defined in consideration of the functions in the present invention, and this may vary depending on the intention or custom of the user, the operator. Therefore, definitions of these terms should be made based on the contents throughout this specification.

In addition, the following embodiments are not intended to limit the scope of the present invention, but merely as an example, and various embodiments may be implemented through the present invention.

1 is an exploded perspective view showing a tablet provided with a handle having a removable assembly function according to the present invention, Figure 2 is a perspective view showing a tablet provided with a handle having a removable assembly function according to the present invention.

As shown in the drawings, the tablet 10 having a handle having a detachable assembly function of the present invention (hereinafter referred to as a tablet having a handle for convenience of description) is made of a metal material and has a pointed portion 22 formed at one end thereof. The upper end is hit by a hammer such as a hammer to be used to cut or process the stone to the pointed portion 22, the fastening hole 21 is formed so as to penetrate the center portion of the tablet 20, The end of the support bar 30 is detachably fastened to the fastening hole 21.

One end of the support bar 30 has a fitting protrusion 31 having a threaded portion at an outer circumference thereof so as to penetrate through the coupling hole 21, and the fitting protrusion protruding through the coupling hole 21. 31, the nut 40 is fastened to the end of the support bar 30 is fixed to the tablet 20.

Such, the support bar 30 is made of a metal material, otherwise it is also possible to form a synthetic resin material. It is also possible to further install a handle made of a synthetic resin material having an elastic portion at the end of the support bar 30.

In addition, the fastening groove 32 is formed to correspond to the front end portion of the support bar 30, the fitting groove penetrating the fastening hole 21 in the state in which the support bar is fixed by pressing the fastening groove 32 with a forceps. By fastening the nut 40 to the protrusion 31, it is possible to prevent the support bar 30 from rotating together with the nut at the time of fastening.

When explaining a defined use state provided with a handle having a removable assembly function configured as described above, first press the fastening groove 32 of the support bar 30 with a gripper such as tongs and then the fitting of the support bar 30. The protrusions 31 are inserted into the fastening holes 21 of the tablet 20, and then the ends of the fitting protrusions 31 protruding from the fastening holes 21 are fastened with nuts 40 to be fixed to the hitting points of the stones. By cutting the stone or by trimming the surface by hitting the top of the tablet 20 with a hammer or the like in the state in which the tip 22 of the tablet 20 abuts, a series of work processes are completed.

Since the tablet 20 is detachably fastened to the support bar 30, the tablet 20 can be worn or replaced by using tablets according to a purpose, thereby reducing maintenance costs.
