[0043] The working principle and usage process of this utility model are as follows: First, when the user needs to adjust the height of the handle assembly 1, he pulls the vertical plate 6. The vertical plate 6 drives the spring 7 to retract forward, causing the adjusting block 8 to disengage from the inside of the adjusting groove 22. Then, he pulls the connecting plate 2 and pulls it to the appropriate position before locking the adjusting block 8 into the inside of the adjusting groove 22, thus achieving the effect of adjusting the height of the handheld part. Then, during welding, he rotates the rotating rod 13, which drives the rotating rod 11 to rotate. The rotating rod 11 drives the shielding plate 14 and the reinforcing vertical bar 15 to rotate, so that the shielding plate 14 blocks the hands of the construction worker, thus preventing the construction worker's hands from being burned by sparks.

[0044] In summary, this construction safety personnel protection equipment changes the traditional problem of non-adjustable height of the handheld part by using an adjustment block 8 to disengage from the adjustment groove 22 and then pull the connecting plate 2. This makes construction welding at different heights less troublesome and does not affect the ease of use for construction personnel.
