[0012] As a further improvement of the above-mentioned scheme, the testing mechanism includes a screw rod rotatably installed inside the installation box and a turntable rotatably installed on one side of the installation box. The turntable and the screw rod are connected to each other through a transmission assembly. The surface of the screw rod is meshingly sleeved with a mounting plate sliding on the front surface of the installation box. The surface of the mounting plate is fixedly connected to a tester. A hook is provided at the bottom of the tester. The transmission assembly includes bevel gears fixedly connected to the screw rod and the turntable, respectively, and the two bevel gears are meshing.

[0013] Through the above technical solution, the rotation of the turntable drives the screw to rotate, so that the tester pulls the antenna until it is separated, and then the test data is obtained. Through the gear transmission setting, the high precision can improve the accuracy of the test.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The utility model selects a suitable fixing hole according to the length of the antenna, and then controls the angle between the fixing block and the antenna through a slide slot, so that the mounting hole can fix the lower side of the antenna, and then limits the position by rotating the limit rod, and rotates the turntable, so that the turntable drives the screw rod to rotate through the transmission component, so that the mounting plate drives the tester and the hook to move downward, and the hook is hung on the threaded rod, and then slowly moves upward through the turntable, and the clamping plate is pulled until the two glued sides of the antenna are separated.
