First claim

The invention claimed is:

1. A detection device, comprising:
a bottom plate, a left spring, a left sliding sleeve, a left positioning column, a left pressing cylinder, a right pressing cylinder, a right sliding sleeve, a right spring, a right positioning column, a supporting block, a guide sleeve, an air cylinder, an inspection tool body, a guide rail, a sliding plate, a servo electric cylinder and a supporting column;
wherein the left sliding sleeve is fixed to an upper portion of the bottom plate on the left of the bottom plate;
wherein an outer side of the left positioning column is fitted with an inner hole of the left sliding sleeve;
wherein the left spring is mounted in the left sliding sleeve and arranged under the left positioning column;
wherein the right sliding sleeve is fixed to the upper portion of the bottom plate and arranged on the right of the left sliding sleeve;
wherein an outer side of the right positioning column is fitted with an inner hole of the right sliding sleeve;
wherein the right spring is mounted in the right sliding sleeve and arranged under the right positioning column;
wherein the left pressing cylinder and the right pressing cylinder are fixed to the upper portion of the bottom plate;
wherein the supporting column is fixed to the upper portion of the bottom plate and arranged between the left sliding sleeve and the right sliding sleeve;
wherein the guide sleeve is fixed to the upper portion of the bottom plate at a middle of the bottom plate; the supporting block is fitted with an inner hole of the guide sleeve at a lower portion of the supporting block;
wherein the air cylinder is fixed to a lower portion of the bottom plate, an output end of the air cylinder is connected with the lower portion of the supporting block, and an upper end of the supporting block contacts with the lower portion of the inspection tool body on the left of the inspection tool body;
wherein the sliding plate is mounted on the upper portion of the bottom plate through the guide rail;
wherein the inspection tool body is fixed to a left side of the sliding plate; and
wherein the servo electric cylinder is fixed to the bottom plate on the right of the bottom plate, and an output end of the servo electric cylinder is connected with a right side of the sliding plate.
