[0055] like Figures 5 to 7 As shown, according to the third embodiment of the present invention, a vacuum nozzle adapter is provided, comprising: an adapter body 1, a buffer block base 2, a nozzle buffer block 3, a buffer assembly, a screwdriver bit 5 of the first embodiment, a fixing plate 6, a reset assembly, the vacuum nozzle 8 of the second embodiment and a locking member 9.

[0058] Specifically, Figures 5 to 7 As shown, the top end of the screwdriver bit 5 passes through the second through hole 31 , is inserted into the first through hole 11 and docks with the output end of the gear offset head tightening tool 10 , and the screwdriver bit 5 can rotate under the drive of the gear offset head tightening tool 10 .

[0059] Specifically, Figures 5 to 7 As shown, the head end of the fixing plate 6 passes through between the adapter body 1 and the buffer block base 2, is inserted into the first through hole 11 to hold the limiting ring 51 of the bit 5, and the head end of the fixing plate 6 is a U-shaped structure.

[0060] Specifically, Figures 5 to 7As shown, the reset assembly is connected to the buffer block base 2 and the fixing plate 6, and is used to reset the fixing plate 6. The reset assembly includes: a pair of placement grooves 71, a pair of reset springs 72, and a pair of reset plates 73; the pair of placement grooves 71 are opened on both sides of the top of the buffer block base 2; the pair of reset springs 72 are placed in the pair of placement grooves 71; the pair of reset plates 73 are arranged on both sides of the fixing plate 6, and the pair of reset plates 73 are inserted into the pair of placement grooves 71 and contact the pair of reset springs 72.

[0061] Furthermore, in this embodiment, a pair of reset sheets 73 and the fixing sheet 6 are integrally formed to improve stability and reliability.

[0062] Further, if Figure 6 As shown, a guide groove 21 is further provided on the top of the buffer block base 2 , and the fixing plate 6 is located on the guide groove 21 for guiding the pulling of the fixing plate 6 .

[0063] Specifically, Figures 5 to 7 As shown, the top of the vacuum nozzle 8 is inserted into the second through hole 31 and fits tightly with the second through hole 31. The vacuum nozzle 8 is sleeved on the screwdriver bit 5, and the screwdriver bit 5 fits tightly with the top of the vacuum nozzle 8. The locking piece 9 connects the top of the vacuum nozzle 8 and the nozzle buffer block 3, and is used to fix the top of the vacuum nozzle 8 on the nozzle buffer block 3. When the vacuum nozzle 8 needs to be replaced, the locking piece 9 is unscrewed to remove the vacuum nozzle 8.

[0064] Further, if Figures 5 to 7 As shown, in this embodiment, the buffer assembly includes: two guide columns 41 and two buffer springs 42; the two guide columns 41 are arranged between the adapter body 1 and the buffer block base 2, and both pass through the nozzle buffer block 3, for guiding the movement of the nozzle buffer block 3; the two buffer springs 42 are sleeved on the two guide columns 41, and both are located between the adapter body 1 and the nozzle buffer block 3, for buffering.

[0065] Furthermore, a shaft sleeve 12 is embedded in the first through hole 11 , and openings are provided on both sides of the shaft sleeve 12 to provide space for inserting the fixing plate 6 .

[0066] When the bit 5 needs to be replaced, first release the lock of the vacuum suction nozzle 8 and remove the vacuum suction nozzle 8. By pulling the tail end of the fixing plate 6, a pair of reset plates 73 will follow and move, squeezing a pair of reset springs 72. At this time, the head end of the fixing plate 6 no longer supports the limit ring 51 of the bit 5.

[0067] When sucking and locking screws, the vacuum suction nozzle 8 and the screwdriver bit 5 are moved to the top of the screw, and then the material is taken vertically downward in the Z direction. The external negative pressure generator is vacuumed, and a vacuum passage is formed through the second through hole 31, the first through hole 11, the two vacuum holes 102 on the vacuum suction nozzle 8 and the internal hollow channel 101 on the suction nozzle buffer block 3, so that the vacuum suction nozzle 8 absorbs the screw when the bottom contacts the screw. After the screw is sucked, the vacuum degree detection table detects whether the current suction state is good through the negative pressure difference. Good negative pressure performance means that the screw is in a good state of suction; the gear offset head tightening tool 10 is lifted with the vacuum adapter, and the screw is sucked to the designated position to complete the tightening action. And when tightening, the screwdriver bit 5 uses the gear offset head tightening tool 10 for buffering, simulating the action of continuous downward pressure during manual operation. In order to avoid hard contact between the vacuum suction nozzle 8 and the screw, the vacuum suction nozzle 8 compresses the two buffer springs 42 through the suction nozzle buffer block 3 for buffering.

[0068] Above, refer to Figures 1 to 7 The vacuum nozzle 8 adapter according to the embodiment of the utility model is described, which has the following beneficial effects:

[0069] 1. No magnetic adsorption, providing a negative pressure screw locking solution for locking in extremely narrow spaces;
