[0031] The transverse movement seat 2 is installed on the base 1 and can move along the transverse direction (i.e., the width direction) of the base 1; the transverse movement seat 2 is used to install the safety clamp 0 to be debugged. Specifically, the transverse movement seat 2 is a flat plate structure and is installed on the base 1 through the second linear guide rail 10 extending along the transverse direction of the base; among them, the slide rail of the second linear guide rail 10 is installed on the base 1, and the slider of the second linear guide rail 10 is fixedly installed with the transverse movement seat 2. In addition, the number of the second linear guide rails 10 in this embodiment is two, but it is not limited to two, and can be adjusted according to actual application requirements.

[0032] The guide rail 3 extends longitudinally (i.e., in the length direction) along the base 1 and is located above the transverse moving seat 2 so as to penetrate through the guide rail channel of the safety tongs 0 to be debugged installed on the transverse moving seat. Among them, the first end of the guide rail 3 is linked and connected with the counterweight 4, and the second end of the guide rail 3 is limited by an anti-tilting seat 11 installed on the base 1; specifically, the first end of the guide rail 3 is hinged to the guide rail seat 12, and the guide rail seat 12 is installed on the base 1 through a first linear guide rail 9 extending longitudinally along the base 1. The slide rail of the first linear guide rail 9 is installed on the base 1, and the slider of the first linear guide rail 9 is fixedly installed with the guide rail seat 12; the number of the first linear guide rails 9 in this embodiment is two, but not limited to two, and can be specifically adjusted according to actual application requirements. The guide rail seat 12 is connected with the counterweight 4 through a steel wire rope 5 passing around a guide wheel 16, and the guide wheel 16 is installed on the base 1 to realize the guiding of the steel wire rope. In addition, as Figure 4 shown, the anti-tilting seat 11 includes a seat body 11a. The seat body 11a has a through hole for the guide rail to penetrate through. The seat body 11a is provided with rolling elements 110 for guiding the movement of the guide rail. The rolling elements 110 are arranged on both the upper and lower sides of the guide rail, and the rolling elements 110 are bearings or rollers or wheels, etc.

[0033] The guide rail 3 of this embodiment has a lug 30 for lifting the safety tongs wedge.

[0034] A first displacement sensor 8 for measuring the moving stroke of the guide rail 3 is installed on the base 1 of this embodiment. The first displacement sensor 8 is installed on the abutting cylinder 6 to realize the integration of the installation structure.
