DETAILED DESCRIPTION

[0020] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0021] See also Figure 1-4 In this embodiment: a horizontal semi-automatic knife locking device comprises a base 1, the upper surface of the base 1 is fixedly connected to a fixed seat 2, a tool handle clamping mechanism 3 is installed on the fixed seat 2, a tool handle clamping mechanism 4 is clamped on the tool handle clamping mechanism 3, a translation device 5 is provided on the upper surface of the base 1, a push plate 6 is provided on one side of the translation device 5, a tool is inserted into the tool handle mechanism 4, the tool handle mechanism 4 is installed on the tool handle clamping mechanism 3, and the tool handle mechanism 4 is fixed by the tool handle clamping mechanism 3. This device is used to position and clamp a tool. When in use, first fix the tool handle mechanism 4 on the tool handle mechanism 4 On, one end of the tool is then inserted into the tool handle mechanism 4. At this time, the tool handle is not locked first. The translation device 5 automatically pushes the tool, and the tool is pushed into the tool handle mechanism 4 until the pushing distance reaches the preset distance. The translation device 5 is reset in the reverse direction and then closed. At this time, the tool handle mechanism 4 locks the tool, and then the tool handle mechanism 4 and the tool are removed from the tool handle clamping mechanism 3 to complete the installation of the tool and the tool handle mechanism 4. This structure can conveniently control the distance that the tool enters the tool handle mechanism 4 so that the distance meets the preset installation distance. It does not require manual measurement and is more convenient.

[0022] like Figure 1 As shown, the translation device 5 includes a shell 51, which is fixedly connected to the base 1. A translation cylinder is installed inside the shell 51. The telescopic rod of the translation cylinder passes through the shell 51 and is fixedly connected to the push plate 6. The translation is driven by the translation cylinder, which replaces manpower and is more labor-saving.

[0023] like Figure 3 and Figure 4As shown, the tool handle clamping mechanism 3 includes a circular fixed tube 31, which is fixedly connected to the fixed seat 2, and a sliding seat 32 is slidably connected inside the circular fixed tube 31. One end of the sliding seat 32 is provided with a T-shaped protrusion 33, and four claws 34 are clamped at the T-shaped protrusion 33 of the sliding seat 32. The outer side of the four claws 34 is sleeved with an annular spring 35, and the side of the claw 34 close to the T-shaped protrusion 33 is provided with a first inclined surface, the inner wall of the fixed tube 31 is provided with an annular groove, and the side wall of the annular groove is provided with a second inclined surface, and the other end of the claw 34 is provided with an outward inclined protrusion 36, and the four claws 34 are in a circular array. It is set that initially, the inclined protrusions 36 on the four claws 34 are located at the annular groove, and the four claws 34 are squeezed by the annular spring, so that the inclined protrusions 36 are opened outward. At this time, the handle mechanism 4 is inserted into the fixed tube 31, reaches the annular groove, and is located between the four claws 34. At this time, when the sliding seat 32 moves to pull the claws 34 into the fixed tube 31, the claws 34 leave the annular groove. Due to the smaller space, the claws 34 no longer open outward, but approach each other inward. The four claws 34 clamp the handle structure to fix the handle structure, which is convenient for inserting the tool and avoiding handle displacement.

[0024] like Figure 3 As shown, the T-shaped protrusion 33 of the sliding seat 32 is fixedly connected to four fixing columns 7 on the side, and the fixing columns 7 are used to separate the four claws 34. The fixing columns 7 separate the claws 34 so that the claws 34 maintain a circular array. A fixing column 7 is clamped between the claws 34 to limit the claws 34 and prevent the claws 34 from contacting and squeezing each other.

[0025] like Figure 3 and Figure 4 As shown, the tool handle mechanism 4 includes a tool handle seat 41, one side of the tool handle seat 41 is conical, and the inner wall of one end of the fixed tube 31 is provided with a second inclined surface, and the second inclined surface is in contact with the tool handle seat 41. The tool handle seat 41 has a conical side threadedly connected to a T-shaped column 42, and the T-shaped column 42 cooperates with four claws 34. The other end of the tool handle seat 41 is cylindrical, and the outer side is threadedly connected to a fastening ring 43. A conical hollow groove is provided on one side of the tool handle seat 41 close to the fastening ring 43, and a circular cavity is provided on one side of the conical hollow groove. An extrusion ring 44 is placed at the conical hollow groove. When the tool is inserted into the tool handle seat 41, the tool is passed through the extrusion ring 44. At this time, the tool is first pushed by the pushing plate 6 to adjust the insertion distance, and then the fastening ring 43 is rotated. As the fastening ring 43 approaches the tool handle seat 41 along the thread, the fastening ring 43 squeezes the extrusion ring 44 into the fixed seat 2, and the extrusion ring 44 squeezes the tool to squeeze and fix the tool to prevent the tool from falling off.

[0026] like Figure 3 and Figure 4As shown, a third inclined surface is provided on the inner side of the fastening ring 43, and both ends of the extrusion ring 44 are tapered, one side fits with the tapered hollow groove, and the other side fits with the third inclined surface on the fastening ring 43, the upper surface of the base 1 is fixedly connected to the mounting seat 8, the mounting seat 8 is fixedly connected to the fixed tube 31, one side of the mounting seat 8 is fixedly connected to the clamping cylinder 9, the telescopic rod of the clamping cylinder 9 passes through the mounting seat 8, and the telescopic rod of the clamping cylinder 9 is connected to the sliding seat 32 by a thread, and the outer side of the tool handle seat 41 is fixedly connected to the blocking ring 10, and the sliding seat 32 is pulled or pushed by the clamping cylinder 9. When the clamping cylinder 9 pulls the sliding seat 32 to slide, the clamping claw clamps the T-shaped column 42 and pulls the T-shaped column 42 into the fixed tube 31, so that the tool handle seat 41 is close to the fixed tube 31, so that one side of the fixed tube 31 contacts the blocking ring 10, one side of the tool handle seat 41 is pulled, and the other side is blocked, thereby making the fixation of the tool handle seat 41 more stable.

[0027] The working principle and use process of the utility model are as follows: the T-shaped column 42 on one side of the tool handle seat 41 is inserted into the fixed tube 31. When the clamping cylinder 9 pulls the sliding seat 32 to slide, the clamping claw clamps the T-shaped column 42 and pulls the T-shaped column 42 into the fixed tube 31. The tool handle seat 41 is close to the fixed tube 31, so that one side of the fixed tube 31 contacts the blocking ring 10, and the tool passes through the extrusion ring 44. The translation cylinder pushes the tool through the pushing plate 6, and the insertion distance is adjusted. After the distance meets the preset installation distance, the fastening ring 43 is rotated. As the fastening ring 43 approaches the tool handle seat 41 along the thread, the fastening ring 43 squeezes the extrusion ring 44 into the fixed seat 2, and the extrusion ring 44 squeezes the tool to squeeze and fix the tool. Then the clamping cylinder 9 pushes the sliding seat 32 to slide, and the clamping claw releases the T-shaped column 42, and the tool handle seat 41 and the tool are removed from the fixed tube 31.

[0028] Of course, the present utility model may have many other implementations. Based on the present implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present utility model.
