[0008] Preferably, a plurality of limiting grooves are formed in the inner wall of the zinc dipping frame, a limiting block is slidably installed in the limiting groove, and one side of the limiting block is fixedly connected with one side of the installation plate.

[0009] Preferably, a plurality of fixing plates are fixed between the connecting frames, and the bottom of each fixing plate is fixed with a fan.

[0013] Compared with the prior art, the utility model has the advantages that:

[0014] 1. The output end of the motor drives the bidirectional screw rod to rotate, and then the adjusting block moves. When the adjusting blocks move close to each other, the support frame is driven to move close, and then the two mounting plates move close to each other, thereby achieving clamping and fixing of the bolt. Then, the output end of the driving motor drives the threaded rod to rotate, and then the connecting block moves up and down, thereby enabling the connecting frame to move up and down. When the connecting frame moves down, the zinc immersion frame enters the zinc immersion box, and thus the bolt can be put into the zinc liquid for galvanizing. This way can avoid the staff from approaching, and multiple bolts can be galvanized at a time, saving time and effort and improving safety and production efficiency.

[0015] 2. The fan is started to generate a certain amount of air, so that the bolt can be accelerated when it is taken out of the zinc liquid, and thus the zinc layer can be better fixed on the surface of the bolt to form a strong zinc plating layer, which helps to improve the service life.
