[0002] The umbrella is a common tool for people to take shelter from the rain. Its main structure consists of an umbrella cover and ribs. The umbrella cover is used to block rain or sunlight, while the ribs support the umbrella cover and guide the umbrella cover to open and close. The ribs are made of high-strength metal or fiber materials, and different numbers of ribs are configured according to the size of the umbrella cover, thereby ensuring that sufficient support is provided in a windy and rainy environment so that the umbrella cover will not collapse, so that the umbrella cover can always maintain a certain shape to block rain or sunlight. The middle rod of the umbrella is set in the middle of the umbrella, which can be used to fix and connect the ribs, and the ribs can be opened and closed through the middle rod so that the user can hold the umbrella. In order to make the umbrella more beautiful and more textured, some umbrella middle rods are made of wood, and an outer grinder is used to make the wood surface smoother, thereby making it feel better to use. The outer grinder can quickly and automatically process the outer surface of the wood, and the processing and grinding speed is fast and easy to use, which greatly reduces the labor intensity of workers.

[0003] Although the above-mentioned existing technology can solve the corresponding technical problems, it still has certain defects: when the existing outer grinder is grinding, a large amount of wood chips will be generated during the grinding process of the wooden middle stick. The smoother the wooden middle stick is grinded, the more and finer the wood chips will be generated. As the grinding head of the grinder continuously rotates and grinds, the wood chips will also fly around due to the centrifugal force of the grinding head, resulting in a very bad air environment around the grinder and serious pollution. The operator must wear protective equipment for isolation, otherwise it is easy to affect the operator's health. Utility Model Content

[0020] The utility model is now further described in conjunction with the accompanying drawings and specific embodiments.

[0021] See also Figure 1-4 As shown, the technical solution adopted in this specific embodiment is: a grinder for the outer side of a wooden middle stick of an umbrella, comprising a base 1 and a lifting seat 2 arranged on the base 1, a grinding head 4 being arranged on the top of the lifting seat 2, a processing table 3 being arranged on the side wall of the lifting seat 2 at a corresponding position below the grinding head 4, the processing table 3 comprising a placement plate 31 arranged on the side wall of the lifting seat 2 at a corresponding position below the grinding head 4, the processing table 3 also comprising an exhaust fan 33 arranged at the bottom of the placement plate 31, an exhaust guardrail 32 connected to the exhaust fan 33 is also arranged on the top surface of the placement plate 31, the exhaust guardrail 32 comprises a fixed guardrail 41 arranged on the top surface of the placement plate 31 and a flow duct 42 arranged in the fixed guardrail 41 and penetrating the inner wall of the fixed guardrail 41, the middle section of the flow duct 42 is provided with a The exhaust pipe 43 is used to start the exhaust fan 33 during grinding to generate negative pressure through the exhaust guardrail 32 to absorb the wood chips generated by grinding. When in use, the grinding head 4 and the processing table 3 are moved to a suitable position through the lifting seat 2, and then the wooden middle stick to be grinded is placed on the placement plate 31 of the processing table 3, and the grinding head 4 is turned on, and the grinding head 4 is lowered and moved through the lifting seat 2, so that the grinding head 4 grinds the wooden middle stick placed on the placement plate 31. While grinding, the exhaust fan 33 is turned on, and the exhaust fan 33 sucks away the gas to generate negative pressure, and the air in the circulation pipe 42 is extracted through the exhaust pipe 43. At this time, the circulation pipe 42 can be extended out of the position of the inner wall of the fixed guardrail 41 to generate negative pressure, thereby extracting the wood chips generated by grinding, effectively reducing the air pollution generated during the grinding process, and no protective equipment is required during use;

[0022] The top surface of the placement plate 31 is also provided with a plurality of anti-slip grooves 34. In this embodiment, three anti-slip grooves 34 are provided, which are conducive to increasing the friction between the wooden middle stick and the placement plate 31, thereby avoiding rolling during processing and affecting the processing effect;
