The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0026] Please refer to Figures 1 to 9, the present utility model provides an instrument for automatically loading gun heads, including a moving frame 1 and an instrument body 2. A slider 3 is arranged on the outer side of the moving frame 1, and a threaded groove 4 is provided inside the slider 3. A first partition 5 is arranged above the moving frame 1, and a second partition 6 is arranged above the first partition 5. Eight first stoppers 7 are arranged on the first partition 5, and twelve second stoppers 8 and a collecting frame 9 are arranged on the second partition 6. The eight first stoppers 7 and the twelve second stoppers 8 form a 96-hole grid pattern. Eight first adjusting blocks 10 are arranged inside the first partition 5. The first adjusting blocks 10 are located below the first stoppers 7. One end of the first adjusting block 10 is provided with a first threaded sleeve 11. Twelve second adjusting blocks 12 are arranged inside the second partition 6. The second adjusting blocks 12 are located below the second stoppers 8. One end of the second adjusting block 12 is provided with a second threaded sleeve 24. A gun head box 13 and twelve limiting rods 14 are arranged inside the instrument body 2. A gun head plate is arranged in the middle of the instrument body 2. The end face of the gun head plate has eight gun head slots 16. A first screw rod 17 and a second screw rod 18 are arranged on the outer side of the instrument body 2. A chute 19 is arranged inside the instrument body 2. An adjusting member is arranged inside the chute 19. The moving frame 1 is slidably connected to the instrument body 2 and is located inside the instrument body 2. The slider 3 is arranged on the adjusting member. The first threaded sleeve 11 is threadedly connected to the first screw rod 17 and sleeved on the first screw rod 17. The second threaded sleeve 24 is threadedly connected to the second screw rod 18 and sleeved on the second screw rod 18.

[0027] In this embodiment, the inside of the instrument body 2 is divided into four areas A, B, C, and D. The moving frame 1 is located between areas A and B. The gun head plate is located in area C. The gun head box 13 is area D. Each gun head slot 16 on the gun head plate can accommodate twelve gun heads. Through this design, traditional manual operation can be avoided, thus liberating both hands, enabling it to automatically complete the loading of gun heads, thereby improving work efficiency and significantly saving various costs.

[0028] Furthermore, both the first screw rod 17 and the second screw rod 18 are driven by a motor 21.

[0029] In this embodiment, by setting the motor 21, the first screw rod 17 and the second screw rod 18 can rotate, thereby adjusting the hole size of the 96-hole grid pattern formed by the eight first stoppers 7 and the twelve second stoppers 8, so as to facilitate keeping gun heads of different sizes in an upright state.

[0030] Furthermore, the number of holes on the gun head box 13 is 96.

[0031] Further, the instrument for automatically loading the gun head further includes two pressing blocks 22, and the two pressing blocks 22 are respectively adhered to the instrument body 2 and are located at the upper end of the instrument body 2.

[0032] In this embodiment, by means of the pressing block 22, it is convenient to shake the instrument body 2, so that the gun head can better enter into the grid formed by 8 first stoppers 7 and 12 second stoppers 8 with 96 holes without using the gun head.

[0033] Further, the pressing block 22 is made of natural rubber.

[0034] In this embodiment, by adopting the natural rubber material, it is convenient to improve the grasping force, thereby avoiding the situation of slipping.

[0035] Further, pulling handles 23 are provided on the front end faces of the gun head plate and the gun head box 13.

[0036] In this embodiment, by means of the pulling handle 23, it is convenient to pull out the gun head box 13 and the gun head plate from the instrument body 2.

[0037] Further, the gun head plate includes two support blocks 26 and a gun head plate body 15. The two support blocks 26 are respectively fixedly connected to the gun head plate body 15 and are located on both sides of the gun head plate body 15. The two gun head plate bodies 15 are also respectively slidably connected to the instrument body 2 and are located in the middle of the instrument body 2. The gun head plate body 15 is slidably connected to the instrument body 2 and penetrates through the middle of the instrument body 2.

[0038] Further, the adjusting member includes a knob 25 and a third screw 20. The knob 25 is fixedly connected to the third screw 20 and is located above the third screw 20. The third screw 20 is rotatably connected to the instrument body 2 and is located in the chute 19 and extends above the instrument body 2. The slider 3 is threadedly connected to the third screw 20 and is sleeved on the third screw 20. By rotating the third screw 20, the moving frame 1 is moved to a suitable height, so as to be applicable to gun heads of different lengths.

[0039] In this embodiment, first, select a suitable tip plate and the tip box 13, and insert them into the instrument body 2. It is necessary to press the tip plate against the 12 limit rods 14. It should be noted that in this design, different tips can be loaded by replacing different tip plates. Then, rotate the third screw 20 to move the moving frame 1 to a suitable height, so as to be applicable to tips of different lengths. Then, drive the 8 first stoppers 7 and the 12 second stoppers 8 to move through the first screw 17 and the second screw 18, so that the 96-hole grid formed by the 8 first stoppers 7 and the 12 second stoppers 8 is adjusted to a diameter size that can clamp the upper end of the tip within the grid. It should be noted that the 96-hole grid formed by the 8 first stoppers 7 and the 12 second stoppers 8, and the size of one hole can accommodate any tip to pass through. At this time, pour the bagged tips into area A so that 96 tips are located in the collecting frame 9. Then, shake the instrument body 2 to make the 96 tips enter the 96 holes of the grid and keep them in an upright state. At this time, the 96 tips, the tip plate, and the tip box 13 are aligned. Then, rotate the first screw 17 and the second screw 18 in the reverse direction to make the 96 tips pass through the grid and fall into the 8 tip slots 16 in area C in sequence. Then, slowly pull the tip plate, so that the 96 tips are inserted into the tip box 13 in area D in sequence under the action of the 8 tip slots 16 and the 12 limit rods 14. Finally, the operation of loading the tips can be completed.

[0040] The above-disclosed is only a preferred embodiment of the present invention, and of course, it cannot be used to limit the scope of rights of the present invention. Those of ordinary skill in the art can understand the whole or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
