Detailed Description

To make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings and embodiments, it being understood that the specific embodiments described herein are only used for explaining the present invention, and are not used for limiting the present invention.

Referring to fig. 1-5, the present invention provides a woodworking sharp mouth graver, comprising a handle 1 and a blade 3, wherein substantially all gravers are used manually. When the wood carving knife is used, the blade 3 is fixed on the handle 1, and then the cutting force of the cutting edge of the carving knife is utilized to realize wood processing by pressing the handle 1 downwards. The blade 3 is connected to the lower end of the handle 1 through the clamping mechanism 2; the clamping mechanism 2 comprises a fixed rod 21 and a clamping sleeve 23, a clamping head 22 is arranged at the lower end of the fixed rod 21, an opening is formed in the clamping head 22, the side surface of the end part of the fixed rod 21 is arc-shaped, and the fixed rod 21 is connected with the clamping sleeve 23 through inner threads and outer threads which are matched with each other; because the blade 3 is of a plurality of types, the knife is a sharp-nose graver, a flat-nose graver, a round-nose graver and the like, before the knife is used, the clamping sleeve 23 rotates anticlockwise, the clamping head 22 is stressed to be reduced and opened, after the blade 3 is placed into the clamping head, the clamping sleeve 23 rotates clockwise, the fixing rod 21 can be shortened, the arc-shaped end of the clamping head 22 is extruded to the blade 3 by the force of the clamping sleeve 23, and then the blade 3 is fixed. The blade 3 comprises a plurality of detachable cutter heads 31, and the head parts and the tail parts of the adjacent cutter heads 31 are fixed through a connecting component. In the engraving process, the cutting edge at the lower end of the tool bit 31 is worn to a certain extent and needs to be replaced, and at the moment, after the connecting assembly on the tool bit 31 is opened, the tool bit 31 can be replaced quickly. The connection mode between the cutter head 31 and the cutter head 31 is more, and the cutter head can be clamped and connected in a sliding mode. In practice, the blade 3 is grooved, and is quickly broken from the groove by utilizing the characteristics of metal to form a new cutting edge.

Preferably, the utility model discloses a coupling assembling is stopper 33 and spacing groove 34 for mutually supporting, and spacing groove 34 is located the afterbody of tool bit 31, and stopper 33 is located the well upper portion of tool bit 31, and the distance between stopper 33 and the spacing groove 34 is less than the height of single blade 3. The utility model discloses a stopper 33 is cylindrically, and spacing groove 34 is arc, and 34 lower extreme diameters of spacing groove are greater than upper end opening diameter. The outer terminal surface of stopper 33 all is arc with the interior terminal surface of spacing groove 34, and the opening width of spacing groove 34 upper end should not exceed 1/2 of circle, need simply strike during the installation, and need just pull out with appurtenance such as pliers during the dismantlement, the stability of 3 jobs of blade when further guaranteeing the sculpture. The tool bit 31 is attached in a manner as shown by the arrow of fig. 4. Meanwhile, the distance between the limiting block 33 and the limiting groove 34 after connection should exceed the length of a single cutter head 31, so that the limiting groove 34 and the limiting block 33 can ensure that the impact force is applied when the blade 3 is knocked, and the purpose of protecting the cutting edge of the cutter head 31 is achieved.

Further, the utility model discloses a coupling assembling is sliding connection's spacing boss 35 and spread groove 36, and the afterbody of adjacent tool bit 31 passes through spread groove 36 sliding connection in the well upper portion of another tool bit 31. In addition to using the limiting block 33 and the limiting groove 34, in the actual use process, a limiting boss 35 and a connecting groove 36 can be used, the adjacent tool bits 31 are respectively provided with the limiting boss 35 and the connecting groove 36, and the connection mode refers to fig. 5. After the cutting edge of the first tool bit 31 is worn to a certain degree, the limiting boss 35 slides out of the connecting groove 36, so that the lowermost tool bit 31 can be taken down quickly, and the second tool bit 31 can be used continuously. In order to further ensure the stability, boss lock catches matched with each other need to be arranged in the limiting boss 35 and the connecting groove 36, so that the cutter head 31 cannot be dislocated when the cutter head is stressed.

Preferably, the blade 3 for connecting the clamping head 22 of the present invention is provided with a fixing groove 32, and the fixing rod 21 is provided with a protrusion (not shown in the figure) matching with the fixing groove 32. When the blade 3 is connected with the chuck 22, after the fixing groove 32 and the protrusion are correctly clamped, the clamping sound can be heard, and then the clamping is tightly fixed through the jacket 23, so that the clamping tightness can be ensured.

In order to achieve better technical effect, the handle 1 of the utility model is hollow, and a plurality of blades 3 with the same model are arranged in the handle 1. Each blade 3 is generally provided with 2-3 cutter heads 31, and each handle 1 can be provided with 2-3 blades 3, so that a maximum of 9 cutter heads 31 can be carried, and the cutter heads 31 can be reused.

Naturally, the present invention can be embodied in many other forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be made by one skilled in the art without departing from the spirit or essential attributes thereof, and it is intended that all such changes and modifications be considered as within the scope of the appended claims.
