[0023] In the embodiments of the present application, the terms "first", "second" are only for description purpose, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include one or more of the features.

[0024] As shown in Figures 1-4 A propeller polishing tool, comprising a machining table 100, a U-shaped plate 101 is installed on one side of the upper surface of the machining table 100 through a lifting mechanism 200, the lifting mechanism 200 can drive the U-shaped plate 101 to vertically lift, a hammer head 102 is rotatably installed on the inner side of the U-shaped plate 101 through a connecting shaft 106, a shaft rod 103 is installed on the outer surface of the hammer head 102, an abutting block 104 is installed on the outer surface of the shaft rod 103, and supporting legs 105 are installed at the four corners of the bottom of the machining table 100.

[0025] In use, first, the propeller is sleeved on the shaft rod 103, and then the propeller is placed on the machining table 100 through the shaft rod 103, and the machining table 100 is supported by the blades of the propeller, at this time, two blades of the propeller are supported on the surface of the machining table 100, and cooperate with the U-shaped plate 101 to form a stable triangular support, so as to ensure the stability of the propeller during polishing. Since the propeller blades are arc curved surface structures, the height of the U-shaped plate 101 can be adjusted by the lifting mechanism 200, so as to adjust the inclination angle of the propeller blades, facilitate the worker to hold the polishing equipment to polish the blades, and improve the portability of operation.

[0026] Specifically, the lifting mechanism 200 includes a mounting block 201 arranged on the machining table 100, a screw rod 202 penetrating through the inside of the mounting block 201 and being threadedly connected, and the upper end of the screw rod 202 is rotationally connected with the bottom of the U-shaped plate 101. The bottom of the U-shaped plate 101 is connected with a limiting rod 203 on both sides, and the end of the limiting rod 203 penetrates to the lower side of the mounting block 201. When the screw rod 202 is rotated, the height of the U-shaped plate 101 can be adjusted by the threaded connection. Since the U-shaped plate 101 is limited by the limiting rod 203, and the screw rod 202 is rotationally connected with the U-shaped plate 101, the U-shaped plate 101 can overcome rotation and achieve the purpose of vertical lifting.

[0027] Specifically, the machining table 100, the shaft rod 103 and the abutting block 104 are all made of wood. On the one hand, the wood material has low cost, which further reduces the cost of the tooling. On the other hand, since the parts in contact with the propeller are all made of wood, the propeller is not easy to be scratched. Since the wood material structure is light, it is also convenient to carry the tooling, and the flexibility of use is improved.

[0028] Specifically, the surface of the machining table 100 is provided with a recess 300, and the lifting mechanism 200 is arranged in the recess 300. By providing the recess 300, the lifting range of the U-shaped plate 101 is increased, thereby increasing the angle adjustment range of the propeller.

[0029] Specifically, the side surface of the recess 300 is provided with a mounting groove 400, and the mounting block 201 is fixed in the mounting groove 400 by bolts 401. By the fixing mode of the bolts 401, the lifting mechanism 200 and the shaft rod 103 and other structures can be conveniently disassembled. Not only is it convenient to replace when damaged, but also after disassembly, the machining table 100 can also be used as an ordinary machining table, achieving the purpose of one thing with multiple uses.

[0030] Specifically, the bottom of the screw rod 202 is provided with a hand wheel 500, and the outer surface of the hand wheel 500 is provided with an anti-skid layer. By providing the hand wheel 500 and the anti-skid layer, it is convenient to rotate the screw rod 202, avoiding the situation of hand slipping.

[0031] The above is a detailed description of the utility model in combination with specific embodiments, which cannot be considered as limiting the specific implementation of the utility model to these descriptions. For ordinary skilled persons in the technical field to which the utility model belongs, without departing from the concept of the utility model, some equivalent substitutions or obvious modifications can be made, and the performance or use is the same, which should be considered as belonging to the patent protection range determined by the submitted claims of the utility model.
