[0030] In this embodiment, the driving mechanism includes a motor 9, a worm 10 and a worm wheel 11. The motor 9 is fixedly mounted on one of the two electric slide bodies 1 to synchronously drive the two fixing mechanisms.

[0031] In this embodiment, a worm 10 is fixedly connected to the output end of the motor 9, and two worm wheels 11 are meshingly connected to the worm 10. The two worm wheels 11 are respectively fixedly connected to one end of two transmission rods 6 for transmission, thereby reducing the force on the output end of the motor 9, preventing damage to the motor 9, and increasing the service life of the equipment.

[0032] In this embodiment, the reinforcement component includes a fixed rod and an eccentric wheel 8. A groove 7 is opened on the telescopic plate 3, and a fixed rod is fixedly installed in the groove 7. An eccentric wheel 8 is rotatably sleeved on the fixed rod. When the anchor rod 15 slides between the two telescopic plates 3, the two sides of the anchor rod 15 interact with the two eccentric wheels 8 on the two telescopic plates 3 respectively, so that the two eccentric wheels 8 rotate a certain angle on the two fixed rods respectively, and the two return springs accumulate force, so that the two eccentric wheels 8 squeeze the two sides of the anchor rod 15, thereby achieving further clamping and fixing of the anchor rod 15, thereby achieving the effect of reinforcing the anchor rod 15.

[0033] In this embodiment, a plurality of return springs are sleeved on the fixed rod, one end of the return spring is fixedly connected to the eccentric wheel 2 8 , and the two eccentric wheels 2 8 are restored to their original state by the action of the two return springs.

The specific structure and working principle of the electric slide body 1, the support block 13 and the reaction support plate 14 can refer to the document with application number: 201920885807.6 proposed in this application. This is the prior art and will not be elaborated in detail.

[0036] In this embodiment, a common anchor rod 15 is disposed between the two fixing mechanisms, and one end of the anchor rod 15 passes through the reaction force support plate 14 .

[0037] Working principle: when in use, first pass one end of the anchor rod 15 through the reaction support plate 14 and between the two telescopic plates 3, then drive and control the motor 9 through the control module 12, so that the motor 9 drives the worm 10 to rotate, and at the same time, the worm 10 and the two worm wheels 11 are transmitted, so that the two worm wheels 11 respectively drive the two transmission rods 6 to rotate on the two sleeve plates 2 respectively, and at the same time, the two transmission rods 6 respectively drive the two eccentric wheels 5 to rotate a certain angle in the two grooves 4 on the two telescopic plates 3 respectively, and at the same time, the two eccentric wheels 5 act on the two telescopic plates 3 respectively, so that the two telescopic plates 3 slide in the two sleeve plates 2 respectively, and one end of the two telescopic plates 3 interacts with the anchor rod 15, and the two eccentric wheels 8 on the two telescopic plates 3 abut against the anchor rod 15, so that the two telescopic plates 3 clamp and fix the anchor rod 15, thereby achieving the effect of fixing the anchor rod 15;

[0038] Afterwards, the two electric slide bodies 1 are driven and controlled by the control module 12, and at the same time, the distance between the reaction support plate 14 and the two fixed components is increased by driving the two electric slide bodies 1 and transmitting the two support blocks 13, so as to achieve the purpose of detecting the solid bearing capacity of the anchor rod 15;

[0039] During this process, when the anchor rod 15 slides between the two telescopic plates 3, the two sides of the anchor rod 15 interact with the two eccentric wheels 8 on the two telescopic plates 3 respectively, so that the two eccentric wheels 8 rotate a certain angle on the two fixed rods respectively, and the two return springs accumulate force, so that the two eccentric wheels 8 squeeze the two sides of the anchor rod 15, thereby further clamping and fixing the anchor rod 15, thereby achieving the effect of reinforcing the anchor rod 15.

[0040] The technical progress achieved by the utility model compared with the prior art is that the anchor rod 15 can be clamped and fixed only by the drive of the motor 9, which reduces mechanical energy consumption and maintenance costs, and can also prevent the anchor rod 15 from detaching during the inspection of the anchor rod 15. It also has a simple structure and higher practicality.
