[0006] A shock-resistant electric drum includes a drum body, a first ratchet fixedly connected to the inner wall of one end of the drum body, and a second ratchet attached to the outer wall of one side of the first ratchet. A telescopic column is welded to the center of the outer wall of one side of the second ratchet, and a fixed sleeve is slidably connected to the outer wall of the telescopic column. A spring is provided between the fixed sleeve and the second ratchet.

[0007] A rubber hose is wound around the outer wall of the drum body, and a stopper is installed on the outer wall of the rubber hose.

[0008] Preferably, one end of the rubber hose is connected to the inner wall of the drum body.

[0009] Preferably, the stopper includes a fixing ring slidably connected to the outer wall of the rubber hose and a groove disposed on the outer wall around the fixing ring.

[0010] Preferably, a servo motor is fixedly connected to the outer wall of one end of the drum body, and a mounting bracket is fixedly connected to the outer wall of the servo motor by screws. A fixing bracket is welded to the top outer wall of the mounting bracket, and a column is fixedly connected to one side outer wall of the fixing bracket by screws.

[0011] Preferably, a handle is installed at one end of the outer wall of the rubber hose.

[0012] Preferably, a rubber suction nozzle is fixedly connected to the outer wall of one end of the rubber hose, and the bottom outer wall of the rubber suction nozzle is hinged to the dust cover.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This design features a shock-resistant electric drum with a ratchet rotation structure inside the drum body. It can be fixed at any working point and is equipped with a rubber hose that can be extended and retracted at will. After the exhaust gas is exhausted, it can be dragged to automatically retract. It is suitable for large, medium and small-sized auto repair shops, 4S after-sales service workshops and other areas. It can also be connected to cars, trucks or other vehicles with electric motors of similar size.

[0015] 2. The shock-resistant electric drum in this design uses a high-temperature resistant rubber hose that is easy to bend and extend. The external structure is a supportive spiral shape, with internal reinforcing ribs for protection. It has good chemical resistance, including shock resistance and corrosion resistance. Furthermore, by adjusting the position of the stop device, the rubber hose can be stopped at any ideal height, making it flexible and practical. Attached Figure Description
