When the lock assembly is installed on the fixing ring on the vertical pole, the movable baffle plate is first pushed inward. At this time, the spring is compressed and the opening is exposed. The movable baffle plate can be loosened by passing the opening through the fixing ring. At this time, the spring resets and drives the movable baffle plate to close the opening. Then, it is only necessary to adjust the distance between the two columns to keep the barrier net in a taut state, which facilitates the rapid installation and disassembly of the barrier net and facilitates the replacement of damaged barrier nets.

[0016] 3. By setting up a lifting control mechanism, when in use, first remove the positioning rod of the locking gear, and then turn the hand crank to drive the gear to rotate. When the gear rotates, it engages with the tooth pattern on the lifting rod, so that the rotation of the gear can control the lifting rod to keep moving in the vertical direction, thereby facilitating the control of the lifting of the blocking net, and then facilitating the adjustment of the height of the blocking net according to the needs of the user when in use. After the adjustment is completed, reinsert the positioning rod to complete the locking of the gear. The operation is simple and can be completed quickly by one person.
