[0021] A plug-in housing 22 is fixed to the front of the top surface of the horizontal plate portion of the bending connecting frame 21. The top plate of the plug-in housing 22 is formed with a plurality of stepped through holes 221 extending downward, with the upper portion being a large-diameter hole section and the lower portion being a small-diameter hole section. The stepped screwdriver bit 1 is inserted into the corresponding stepped through hole 221. The bottom surface of the upper large-diameter section of the screwdriver bit 1 is pressed against the bottom surface of the large-diameter hole section of the corresponding stepped through hole 221. The lower small-diameter section of the screwdriver bit 1 is in the lower small-diameter hole section of the corresponding stepped through hole 221. The middle to the lower portion of the lower small-diameter section of the screwdriver bit 1 extends out of the bottom end of the stepped through hole 221 and the through groove formed on the front portion of the horizontal plate portion of the bending connecting frame 21.

[0022] A rear stepped through hole 23 extending horizontally backward is formed on the rear wall surface of the large diameter hole section of the stepped through hole 221, and the rear portion of the rear stepped through hole 23 is a small diameter hole section and the front portion is a large diameter hole section;

[0023] A support plate is fixed to the rear of the horizontal plate of the bending connecting frame 21, and a plurality of ventilation right-angle elbows 24 are located above the rear of the horizontal plate of the bending connecting frame 21. The middle of the horizontal pipe of the ventilation right-angle elbow 24 is clamped in the corresponding clamping installation through hole on the support plate. A positioning pressing rod 25 is inserted in the horizontal pipe of the ventilation right-angle elbow 24. The front part of the positioning pressing rod 25 is inserted in the small diameter hole section of the rear stepped through hole 23. The front end of the positioning pressing rod 25 is fixed. There is an anti-slip pressing block 26 with an outer diameter larger than that of the positioning pressing rod 25 (it is detachable, such as the front end of the positioning pressing rod 25 is formed with a threaded portion which is threaded into the threaded hole at the rear end of the anti-slip pressing block 26), the anti-slip pressing block 26 is inserted into the large diameter hole section of the rear stepped through hole 23, the outer diameter of the anti-slip pressing block 26 is larger than the inner diameter of the small diameter hole section of the rear stepped through hole 23, and the front end of the anti-slip pressing block 26 faces the rear side wall of the upper large diameter section of the corresponding batch head 1.

[0024] Furthermore, the rear portion of the positioning pressing rod 25 is located in the horizontal tube portion of the ventilation right-angle elbow 24, and a sealing ring 6 is clamped between the outer wall of the rear portion of the positioning pressing rod 25 and the inner wall of the horizontal tube portion of the ventilation right-angle elbow 24. The sealing ring 6 is nested in an annular groove formed on the inner wall of the horizontal tube portion of the ventilation right-angle elbow 24, and the inner wall of the sealing ring 6 is pressed against the outer wall of the rear portion of the positioning pressing rod 25.

[0025] Furthermore, a radial extension portion 251 is formed on the rear outer side wall of the positioning pressing rod 25 , the outer diameter of the radial extension portion 251 is larger than the inner diameter of the small diameter hole section of the rear stepped through hole 23 , and the radial extension portion 251 is located at the rear of the plug-in housing 22 .

[0026] Furthermore, a buffer spring is inserted and sleeved on the positioning pressing rod 25 , one end of the buffer spring is applied to the front end surface of the radial extension portion 251 , and the other end is applied to the rear wall surface of the plug-in housing 22 .

[0027] Furthermore, a protective cover is fixed to the rear of the horizontal plate portion of the bending connecting frame 21, and all the ventilation right-angle elbows 24 are located in the protective cover.

[0028] Furthermore, the bottom ventilation pipes of all ventilation right-angle elbows 24 extend out of the through slot at the rear of the horizontal plate portion of the bent connecting frame 21 .

[0029] Furthermore, the front end of the rear stepped through hole 23 is aligned and corresponds to the front through hole extending forward formed on the front wall surface of the large diameter hole section of the stepped through hole 221;

[0030] The bottom ventilation pipes of all ventilation right-angle elbows 24 extend out of the through grooves at the rear of the horizontal plate portion of the bent connecting frame 21 and are connected to the air outlets of the corresponding solenoid valves in the pneumatic equipment (the pneumatic equipment is not shown in the accompanying drawings. The pneumatic equipment includes an air pump, multiple solenoid valves, and interconnected air pipes, etc., and the air pump and the solenoid valves are electrically connected to the control host through electrical connecting lines and are controlled and operated by the control host. This is a conventional structure and will not be described in detail here).

[0031] When in use, air is ventilated through the vent right-angle elbow 24, so that the positioning pressing rod 25 is pushed forward, and the anti-slip clamping block 26 is pressed against the side wall of the corresponding bit 1, pressing it against the inner wall of the large-diameter hole section of the corresponding stepped through hole 221, that is, the bit 1 is clamped between the end face of the anti-slip clamping block 26 and the inner wall of the large-diameter hole section of the corresponding stepped through hole 221, making it impossible to take it away, that is, all the bits 1 are fixed.

[0032] When the corresponding screwdriver bit 1 is needed, the corresponding solenoid valve can be switched through the control host, so that the ventilation right-angle elbow 24 at the corresponding screwdriver bit 1 stops ventilation. At the same time, the gas in the ventilation right-angle elbow 24 enters the exhaust port of the solenoid valve and is discharged. The buffer spring is elastically reset, so that the anti-slip clamping block 26 no longer presses against the outer wall of the corresponding screwdriver bit 1. At this time, the screwdriver bit 1 can be manually taken and installed in the pneumatic bolt gun for use, which is very convenient.

[0033] Moreover, it can control the corresponding program in the control host. For example, in this installation, a corresponding batch head 1 cannot be used, and the corresponding solenoid valve is operated, so that the anti-skid clamping block 26 is always pressed against the corresponding batch head 1, so that the operator cannot take it. The batch head 1 that can be used in this installation does not have its corresponding anti-skid clamping block 26 pressed against it, so that it can be taken and used, making it convenient to take and select the batch head 1, easy to take, and easy to operate.
