Through adopting above-mentioned technical scheme, because the spring is not the full recovery deformation to the deformation power of spring needs to be overcome to the hold-in range, and the tension that leads to the hold-in range to bear is too big, then reduces the life of hold-in range easily, damages the acceleration, and is close to each other through two sliders of gasbag restriction, prevents that the hold-in range from receiving the effect of spring, and leads to from the tension too big, can adjust the distance of two sliders through the degree of inflation of gasbag simultaneously.

Optionally, be equipped with the confession on the inserted bar the pressure sensor of hold-in range butt, be equipped with on the workstation and be used for showing the display screen of pressure sensor data.

Through adopting above-mentioned technical scheme, pressure sensor's setting can detect the hold-in range to the pressure that the inserted bar produced to show through the display screen, thereby can detect hold-in range lax degree according to the hold-in range to the pressure variation of inserted bar, can adjust the gassing volume of gasbag simultaneously, with the lax degree of adaptation hold-in range.

Optionally, the valve is an electromagnetic valve, and the pressure sensor is used for controlling the electromagnetic valve to open and close.

Through adopting above-mentioned technical scheme, can be through the numerical range control that sets up pressure sensor whether to solenoid valve transmission signal, if numerical value on the display screen surpasses this scope, then pressure sensor gives the solenoid valve with signal transmission to the solenoid valve is opened, realizes the gassing work of gasbag, and then the hold-in range is taut under the effect of spring, and pressure sensor's numerical value resumes to setting for the scope, and the solenoid valve is closed, thereby the removal of the regulating slide block that can self-adaptation, with the taut hold-in range of self-adaptation.

Optionally, a nut for limiting the synchronous belt to be separated from the inserted rod is arranged on the inserted rod.

Through adopting above-mentioned technical scheme, prevent that the hold-in range from breaking away from the inserted bar.

In summary, the present application includes at least one of the following beneficial technical effects:

1. after the synchronous belt is loosened, the position of the idler wheel can be adjusted through the adjusting assembly, and the idler wheel and the driving wheel are controlled to be away from each other, so that the synchronous belt can be tensioned;

2. this application passes through the setting of spring, realizes the automatic taut work of hold-in range, and can prevent through the setting of gasbag that the hold-in range from receiving the effect of spring, and lead to self-tension too big to setting up through solenoid valve and pressure sensor reaches the removal of the adjusting block of self-adaptation, with the purpose of the taut hold-in range of self-adaptation.
