One end of the pressing block 13 is hinged on the workpiece mounting seat 12, and the other end of the pressing block is fixed with the workpiece mounting seat 12 through the quick locking mechanism 15, so that the workpiece is fixedly mounted on the workpiece mounting seat 12. Wherein the drive mechanism 14 comprises a motor and a gearbox.

As shown in fig. 1-2, the screwing mechanism 2 includes a fixing bracket 21, a guide rail 22, a pressure rod 23, a reset piece 24, a torque gun 25 and a slide block 26, the guide rail 22 is vertically arranged on the fixing bracket 21, the slide block 26 is arranged on the guide rail 22, and the slide block 26 is connected with the fixing bracket 21 through the reset piece 24 so as to drive the slide block 26 to move upwards to the highest position; wherein, the restoring member 24 may use a spring. The torque gun 25 is arranged on the sliding block 26, and different screw drivers are selectively installed on the torque gun 25 according to the shapes of different screws. Preferably, the end of the screwdriver has magnetism, so that the screwdriver can be attracted to a screw when in use, and the screwdriver is convenient to use. The pressing rod 23 is arranged on the sliding block 26, and an operator drives the sliding block 26 to move downwards by driving the pressing block 23, so that the torque gun 25 screws a workpiece.

In one embodiment, as shown in fig. 1, the screwing mechanism 2 further comprises a gear and a rack 27, the gear is arranged on the slide block 26 through a rotating shaft 28 and is connected with the pressing rod 23, the gear is driven to rotate by the pressing rod 23, and the rack 27 is vertically fixed on the bracket 21 and is meshed with the gear. When the pressing lever 23 is pressed, the gear turns the lever, effecting a downward movement of the slider 26 while the restoring member 24 continues the force required for restoring, and when the pressing lever 23 is released, the slider 26 is moved upward by the restoring force of the restoring member 24.

In one embodiment, as shown in fig. 1, the screwing mechanism 2 further comprises a position sensor 29, and the position sensor 29 is disposed on the fixing bracket 21 to send a signal that the slide block 26 is reset to the position.
