Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, an adapter for tool bit replacement comprises an adapter 1, wherein a left adapter wing 2 is disposed on the left side of the adapter 1, a right adapter wing 3 is movably clamped on the right side of the left adapter wing 2, the outer diameter of the left adapter wing 3 is equal to the inner diameter of the left adapter wing 2, the left device cavity 14 of the right adapter wing 3 can be more closely attached to the inner cavity of the left adapter wing 2 by setting the outer diameter of the left adapter wing 3 is equal to the inner diameter of the left adapter wing 2, so that excessive shaking is avoided, the connection between the left adapter wing 2 and the device cavity 14 is firmer, a tool device 4 is fixedly mounted on the left side of the left adapter wing 2, a tool mounting opening 5 is formed on the right side of the right adapter wing 3, a tool 6 is movably mounted inside the tool mounting opening 5, three fixing holes are formed on the left side of the tool 6, in addition, the three fixing holes on the left side of the cutter 6 are distributed in a triangular shape, the cutter 6 can be installed with the joint right wing 3 through the three fixing holes by arranging the three fixing holes on the left side of the cutter 6, the stability of the cutter 6 is ensured, in addition, the three fixing holes on the left side of the cutter 6 are distributed in a triangular shape, because the triangular shape has very good stability, the fixing position is more stable and firm, therefore, the cutter 6 cannot sway left and right in the working process of the cutter 6 and can keep very good stability, the left side of the joint right wing 3 is provided with a device cavity 14, a partition plate 7 is fixedly arranged inside the device cavity 14, a first reset spring 8 is fixedly arranged at the top of the partition plate 7, a first latch 9 is fixedly arranged at the top of the first reset spring 8, and one ends of the first latch 9 and a second latch 11, which are far away from, the first latch 9 and the second latch 11 are trapezoidal, and the end of the first latch 9 and the end of the second latch 11 away from the partition plate 7 are both provided with the convex rib, so that the first latch 9 and the second latch 11 can be more conveniently pressed and detached without sliding and can not cause great resistance when being inserted, in addition, the first latch 9 and the second latch 11 are trapezoidal, so that the first latch 9 and the second latch 11 can be smoothly inserted through the trapezoidal edge when being inserted into the joint left wing 2, and are more convenient and rapid, the first latch 9 penetrates through the cavity of the joint left wing 2 and the joint right wing 3 and extends out of the joint left wing 2, the bottom of the partition plate 7 is fixedly provided with the second return spring 10, and the bottom end of the second return spring 10 is fixedly provided with the second latch 11, the right side of the joint right wing 3 is provided with three cutter mounting holes 12 on the front side of the cutter mounting opening 5, the number of the cutter mounting holes 12 is three, the distribution positions of the three cutter mounting holes 12 are the same as the positions of the fixing holes arranged on the cutter 6, the cutter 6 can be more firmly mounted by setting the number of the cutter mounting holes 12 to be three, and the distribution positions of the three cutter mounting holes 12 are the same as the positions of the fixing holes arranged on the cutter 6, so that the fixation is more stable through the stable relation of the triangle, the fixation cannot easily shake, and the fixation is more convenient, if the position of the cutter 6 is not stable enough, the cutter 6 is easily shaken, the shaking of the cutter 6 can cause the low processing safety on one hand, the processing quality on the other hand is not high, and the cutting surface of the processed part is not neat because the shaking of the cutter is easily caused, therefore, the cutting quality is not good, the stability of the enterprise quality is not facilitated, the friction ribs 13 are arranged on the left side of the cutter mounting hole 12, the number of the friction ribs 13 is two, the two friction ribs 13 are respectively positioned on the front side and the back side of the joint right wing 3, the friction between the hand of a person and the joint right wing 3 is larger through the arrangement of the two friction ribs 13, so that the hand of the person cannot easily slide, the installation and the disassembly are safer, the arrangement of the other two friction ribs 13 respectively positioned on the front side and the back side of the joint right wing 3 is to ensure the symmetrical attractive appearance and the taking habit of the hand of the person, so that the operation is more convenient, if the friction ribs 13 are not arranged, the person touches a smooth metal body when taking the joint right wing 3, the friction between the metal body and the hand of the person is very small, the joint right wing 3 is very easily dropped during the installation and the disassembly, the falling of the joint right wing 3 very easily causes the damage of the cutter 6, so that the friction rib 13 needs to be provided.

The theory of operation, when this device work, at first when the installation, because the trapezoidal setting of first latch 9 and second latch 11 for this connects right wing 3 directly push connect in the left wing 2 joint fixed can, in addition also fairly simple when dismantling, only need to press first latch 9 and second latch 11 inside and just can make this first latch 9 and second latch 11 break away from and connect the left wing 2, the completion is dismantled, can.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
