[0057] The following specific embodiments will further illustrate the present application in conjunction with the above-mentioned drawings. Specific embodiments

[0058] The following specific embodiments are exemplary rather than restrictive. They are intended to provide a basic understanding of the present application and are not intended to identify the key or decisive elements of the present application or to limit the scope to be protected. As long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way.

[0059] When a component is considered to be "provided on" another component, it can be directly provided on the other component or there may be an intermediate component at the same time. When a component is considered to be "connected to" another component, it can be directly connected to the other component or there may be an intermediate component at the same time.

[0060] It can be understood that the terms "perpendicular, equal" are used to describe an ideal state between two components. In actual production or use, there may be a state between two components that is approximately perpendicular or equal. For example, in combination with numerical descriptions, perpendicularity can refer to the angle between two straight lines being in the range of 90°±10°, perpendicularity can also refer to the dihedral angle between two planes being in the range of 90°±10°, and perpendicularity can also refer to the angle between a straight line and a plane being in the range of 90°±10°. The two components described as "perpendicular" may not be absolute straight lines or planes, but may be roughly straight lines or planes. From a macroscopic perspective, a component can be considered a "straight line" or a "plane" if the overall extension direction is a straight line or a plane.

[0061] Unless otherwise defined, when the term "plurality" is used to describe the number of components, it specifically means that the components are two or more.

[0062] The embodiment of the present application provides a torque detection platform for detecting the torque of an electric screwdriver, including a base, a torque detector, two support columns and a bracket. The base is provided with a level meter for detecting whether the base is in a horizontal state. The torque detector is arranged on the base.

The bracket is slidably connected to the two support columns, the bracket is connected to the end of the elastic member away from the base, the bracket is used to install the electric screwdriver, and the electric screwdriver is acted on by an external force. The bracket presses the elastic member so that the screwdriver head of the electric screwdriver moves along the second direction and is connected to the torque detector. The present application uses the support column to be perpendicular to the base, so that the bracket moves in a direction perpendicular to the base, stably controls the vertical angle, detects the horizontal state of the base through the level meter, facilitates the adjustment of the base, and controls the force of the piezoelectric screwdriver and the bracket through the elastic member, improves the accuracy and stability of the torque detection, improves the compliance rate of the detection, and reduces the impact of excessive torque on the locking parts.
