[0023] As Figures 1-3 shown, a multifunctional needle starting device includes a base 1. A linear slide rail 2 is provided on one side of the base 1. A lifting block 3 is movably clamped on the linear slide rail 2. An adjusting screw 4 is provided on the top of the base 1. A vertical through hole is provided in the lifting block 3. A nut block 5 is installed in the vertical through hole. The lower end of the adjusting screw 4 extends into the vertical through hole and passes through the nut block 5. The adjusting screw 4 is threadedly connected with the nut block 5. The upper end of the adjusting screw 4 is exposed above the base 1. A needle starter 6 is installed on the lifting block 3. A lifting screw 7 is provided on the top of the lifting block 3. The lower end of the lifting screw 7 is connected to the needle starter 6. The upper end of the lifting screw 7 is exposed on the top of the lifting block 3. By rotating the adjusting screw 4, the nut block 5 is restricted from rotating synchronously. The nut block 5 is fixedly connected to the lifting block. Therefore, the nut block 5 will move up and down together with the lifting block. The height of the needle starter can be adjusted separately by using the lifting screw. The lifting screw is for fine adjustment, while the adjusting screw is for coarse adjustment.

[0024] On both sides of the upper opening of the vertical through hole in the lifting block 3, pressing screws 8 are installed. The pressing screws 8 press down on the nut block 5, so that the nut block 5 is fixed to the lifting block 3. When the adjusting screw rod 4 rotates, the nut block 5 drives the entire lifting block 3 to move linearly along the axial direction of the adjusting screw rod.

[0025] A radial screw hole is provided on the side surface of the lifting block 3. A radial locking screw 9 is inserted into the radial screw hole. The radial locking screw 9 is locked and faces the side surface of the linear slide rail 2. A handle 10 is provided on the radial locking screw 9. The radial locking screw 9 can be conveniently rotated by using the handle 10. After adjusting the position of the lifting block, rotate the handle to drive the radial locking screw, so that the radial locking screw presses against the side surface of the linear slide rail, realizing the radial locking of the lifting block. At this time, it is ensured that the lifting block will not drop. When the height needs to be adjusted, only need to loosen the radial locking screw, and the height adjustment purpose can be completed by rotating the adjusting screw rod.

[0026] A limit screw 11 is also provided on the side surface of the lifting block 3. The limit screw 11 is locked into the lifting block 3 from the radial direction and abuts against the side surface of the linear slide rail 2. A limit screw is installed above and below the radial locking screw respectively, which together play a role in radially locking and positioning the lifting block. The limit screw can be a countersunk head screw, and it can be loosened when adjustment is needed.

[0027] A rotating nut 12 is provided at the upper end of the adjusting screw rod 4, which is convenient for direct manual twisting.

[0028] The needle lifter 6 includes a thimble 61, and a main spindle rod 62 and side arms 63 integrally formed. One side arm 62 is formed on each side of the main spindle rod 62. A through hole is provided in the main spindle rod 62. The upper part of the thimble 63 extends into the through hole. The lower end of the lifting screw rod 7 extends into the through hole and is connected to the thimble 61. A transverse positioning screw 64 is provided on the side arm 63. The transverse positioning screw 64 passes through the main spindle rod 62 and the thimble 61. After adjusting the position of the thimble by the lifting screw rod, lock the transverse positioning screw to complete the positioning.

[0029] The bottom surface of the base is provided with anti-slip lines, so that it will not shift easily when placed.

[0030] The present utility model mainly processes precision devices such as watches. First, adjust the position of the lifting block through the adjusting screw rod, and then adjust the height of the thimble through the lifting screw rod, so that the thimble is kept at the best processing position.

[0031] It should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
