Description of the new model: [Technical field to which the new model belongs] This new model relates to a type of pneumatic safety gear, and in particular to a suspension mechanism that can prevent the rotary shaft of the pneumatic tool from being accidentally touched during work, and the rotary shaft of the pneumatic tool Stopped protective cover. [Previous technology] -Pneumatic tools driven by high pressure generally have many parts inside, including two parts made of metal casting, grabbing in the air inlet channel, powering air motor, providing grinding, etc. Metal tool heads and external air compressors that provide a source of compressed air. In addition, due to the extremely high torque of the pneumatic tool during operation, the industry has designed an auxiliary grip for the pneumatic guard. Its purpose is to allow the operator to support the pneumatic tool with both hands, thereby improving the stability of the work during the operation. And security. As mentioned above, a pneumatic tool for grinding is used as an example. The pneumatic motor powered by the pneumatic tool can drive _ the internal shaft to rotate, and then link the grinding disc at the end of the shaft to perform grinding. It is hoped that the rotation of the grinding disc can be temporarily stopped without pressing the on / off switch. Therefore, the conventional technique further sets a rotary shaft suspension assembly on the pneumatic tool to meet the above requirements. The rotating shaft suspension component is composed of a stopper and an elastic member, wherein the elastic member is sleeved on the stopper 'and the head of the stopper is exposed outside the casing of the pneumatic tool, and the tail of the stopper is penetrated In the housing of the pneumatic tool, when the user presses the head of the supporting member, the tail of the catching member contacts the rotating shaft to temporarily stop the rotating of the rotating shaft. Value 仵> The idea is that the head of the stopper of the shaft suspension assembly M268152 is directly exposed to the pneumatic tool. As a result, the user may accidentally touch the surrounding tools while using the pneumatic tool. The shaft suspends the component on the pneumatic tool and stops the shaft by mistake, which affects the smoothness of the grinding work. [New content] The purpose of the new Saint Dagger is to provide a protective cover for the suspension of the rotary shaft of the pneumatic tool, which can prevent the pneumatic tool from accidentally touching the stopper on the milk moving sanitary equipment during work, and the pneumatic Based on the above purpose, the present invention provides a suspension of the shaft of a pneumatic tool: a protective cover of the piece 'wherein the pneumatic tool has a driveable rotating shaft suspension assembly arranged in the housing of the pneumatic tool And the rotating shaft sleeve is mainly composed of a stopper and an elastic member, the elastic member is outside and the stopper is on, and the head of the stopper is exposed to the housing of the pneumatic tool, and the tail of the stopper is When the head of the stopper is touched by the user in the housing of the pneumatic tool, the tail of the stopper is connected with the rotation of the second part: the rotation of the axis, and the new model mainly lies in the double body of the pneumatic tool A protective cover is arranged on the protective cover, and the protective cover is the peripheral edge of the cover part, and the stopper is used in #; § The second head of the stopper is aligned with the head of the catch, and because the protective cover is at least aligned with Designed to prevent pneumatic tools During the work period, Menda touched the stopper and stopped the shaft by mistake. Chadou because of inadvertently knowing about the preferred embodiment and technical content of the new model, I will refer to the diagram M268152. [Embodiment] Please refer to "Figure 1 and Figure 2" together. In this embodiment, the pneumatic tool The housing 110 of the 100 has a rotating shaft 120 therein, and the rotating shaft 120 can be driven by a motor (not shown) also configured inside the housing 110, and the starting and otherwise of the motor can be pressed by a pressing on / off switch. 3 Controlled. One end of the above-mentioned rotating shaft 120 extends out of the housing 110. According to this embodiment, the end of the rotating shaft 120 is, for example, connected to a grinding disc 140, and the rotating shaft 120 is rotated by the motor γ, thereby interlocking the grinding disc 14 〇 to carry out the work of grinding. The auxiliary handle 150 connected to the housing 11 near the rotating shaft 20 is used to provide the user with a grip to improve work stability and safety. In addition, a semi-circular mask 160 can be connected to the bottom of the casing 110, and this mask 160 will cover a part of the grinding disc 14o to prevent the grinding liquid or grinding debris sprayed during the grinding process. In addition, the rotation shaft suspension assembly 17 is arranged on the casing 110 of the pneumatic tool 100. In the present embodiment, the rotation shaft suspension assembly-the support stop and the-elastic member are formed. Elasticity please: It is a compression spring, the sleeve is placed on the stopper 172, and the head of the stopper 172 is exposed outside the casing 11G of the pneumatic guard, and the stopper 172: the tail is penetrated by the pneumatic In the housing 110 of the tool 100, when the dust stopper 172 @ head is used, the tail of the broadcast stopper 172 can be brought into contact with the rotating shaft 20 to temporarily stop the rotation of the rotating shaft 120. It is worth noting that, in this embodiment, an eighteenth and eighth side cover 180 is further arranged on the housing 110 of the work and 100, and the protective cover 180 is attached to the head of the stopper 172. The periphery of Qiu's 、 鏠, < head 邛, and the stopper 172 is at least aligned with the head of the catcher m when the user M268152 does not press ['Sorrow'. Since the protective cover 180 is aligned with the head of the stopper 172, it is possible to prevent the pneumatic tool 100 from accidentally stopping the rotating shaft 120 due to accidentally touching the stopper ⑺ during operation. In other words, after the protective cover 180 is added, in addition to the user stopping the rotation shaft 12 by pressing the stopper m as required, the objects that he may accidentally touch the stopper 172 are all isolated by the protective cover. Since the rotating shaft 120 cannot be stopped through the stopper 172, the smoothness of the operation can be maintained. ^ As mentioned above, the protective cover 180 in this embodiment is attached to a part of the periphery of the head of the stopper 172. Of course, the new type is not limited to this type, and the protective cover 180 can also be attached to the stop. The entire periphery of the head of piece 172. In addition, in this embodiment, when the stopper 172 is not pressed by the user, the protection cover 180 is designed to be aligned with the head of the stopper 172. Of course, as you are familiar with the technology, the new model does not require Restricted to this type, the protective cover 180 can also be designed to protrude from the head of the stopper 172, in other words, the head of the stopper 172 is slightly recessed into the protective cover 18o, which can also prevent the pneumatic tool 1 〇〇 During operation, the rotation shaft 120 was stopped by accident because the stopper 172 was accidentally touched. Although the present invention has been disclosed in the preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in this art, without departing from the spirit and scope of the present invention, should make some changes and retouches, which should be covered by the present invention. Within the new model, the protection scope of this new model shall be determined by the scope of the attached patent application.
