New description: [New technical field] This creation is about a pneumatic tool (4). The prior art pneumatic tool includes a main seat, a front seat, a tool set and a pneumatic motor. The tool set and the air motor are respectively fixed to the front seat and the main seat, and the front seat is fixed to the main seat. The 'pneumatic motor includes a cylinder and a cover, the cover is attached to the cylinder-end' to prevent the air motor from leaking, but the tool set of the pneumatic tool generates great vibration during operation, so that The cover body gradually loosens under long-term use, thereby causing the air motor to leak. / There is a problem with how to improve the cover of the air motor is susceptible to shocks. [New content] The main purpose of this creation is to provide a pneumatic tool with a structure of an urgent air motor. In order to achieve the above object, the pneumatic tool (4) of the present invention comprises a main casing, a front casing, a tool set, a pneumatic motor and a pressing member, the main casing having a wall and a first fixing section The inner wall encloses a motor chamber, the first fixed portion ring is disposed on the shaft wall; the front housing has a tool chamber, and the front L body end is fixed on the main housing; the tool set Rotatablely fixed to the tool, the pneumatic motor is fixed to the motor chamber, the air motor includes a cover shaft, the cover is attached to one end of the air motor, and the spindle is connected to The tool set end 'the air motor can be driven by the high pressure gas, the mandrel can be rotated about its axial direction, and the set rotates; the pressing member has a perforation, a first core surface, and a second abutment a second fixing section 'the perforation for the mandrel to wear" and the 'the first turning surface is located near one side of the main casing, the first abutting surface is against the air motor, the second abutting The abutment is located away from the side of the main casing. The first fixing section surrounds the circumference of the first abutting surface and the second abutment Between the edges of the face, the second fixed section is fixed to the first section, so that the first escaping surface is in close contact with and presses the air motor. Therefore, the structure of the pneumatic escort (4) of the present invention can make the air motor more compacted, so that the cover body is less susceptible to shock when the tool set vibrates, so that the air motor is less secreted. Can turn to read performance. [Embodiment] Hereinafter, the structural features of the present creation and the effects of its intended achievement will be described by way of a preferred embodiment, and the method of turning over the confession should be clarified. 1 to 3, in the preferred embodiment of the present invention, the pneumatic tool Lu (4) comprises a main casing 10, a front casing 2, a tool set 3〇, a pneumatic horse up to 40 and a pressing member 50, the main casing 1 has an inner wall u, a first solid block #12 and a control valve group, the inner wall I defines a motor chamber I], and the first fixed portion 12 is ring-shaped On the inner wall! ! The control valve group includes a flow control valve Η and a trigger unit 15 that can be used to control the flow rate of the high pressure gas flowing into the pneumatic tool; the front housing 20 has a tool chamber 2 The 20-end is fixed to the main casing 10. 4 M399005 The tool set 30 is rotatably fixed to the tool chamber 21, and the tool set 30 includes a tool head 3 - a rotating portion 32 and two striking blocks 33, and the end of the tool head 31 protrudes from the front shell The body 20 can be connected or snapped to a workpiece or a tool. The rotating portion 32 includes a card slot 321 and an accommodating space. Each of the striking blocks 33 includes a hole 33 and a rainbow head 31 _ two striking block % The tool head 31 can be accommodated in the valley space. The other end of the tool head 31 can cooperate with the shape of the hole 33 of the striking block 33. The rotating block 32 can mechanically move the tool head 31 to rotate. The air motor 40 is fixed to the motor chamber u. The air motor 4 includes a mandrel 4 - a cylinder 42 and a cover 43 . The sister 41 is accommodated in the cylinder 42. At the end of the cylinder 42, the cover is used to prevent the gas in the A rainbow 42 from being exposed. The end of the mandrel 41 protrudes from the cover body and is connected to the 30-end of the red set. The air motor 41 is driven by the high pressure gas to rotate the spindle 41 about its axial direction and to drive the tool set 3 to rotate. Referring to FIG. 3 , FIG. 3A and FIG. 4 , the pressing member 50 has a through hole 51 , a sinus surface 52 , a second abutting surface 53 and a second fixing section for the mandrel 41 to pass through. The first abutment surface 52 is located adjacent to the main housing side, and the first sinus surface 52 abuts against the air motor. For example, the first abutment surface 52 abuts against the air motor 4 The second button abutting surface 53 is located on one side of the main casing 1 ,, and the second fixing portion 54% surrounds the periphery of the abutting surface 52 and the second abutting surface μ 5 M399005 where 'the second HI is determined in the first-fixed section, let =: air motor' in this embodiment, the first-fixed = - recognized 54 material has - the section of the The first-side side-weaving crepe is attached to the cover body 43 and the remaining horse (four) is added. Compared with (10), the pressing member % further includes a ring convex portion 55 extending from the first abutting surface 52 toward the main body 10. The ring convex portion 55 includes a closing surface 551, and the air motor 4 〇
包含一外軸44，該環凸部55酸略大於魏動馬達4〇外 徑，令該内周面551緊貼於該外環面44上，藉此令該氣動馬 達被壓迫的較緊實，使該蓋體料因工胁缸作時所產生的 震動而遭震鬆。An outer shaft 44 is included. The annular convex portion 55 is slightly larger than the outer diameter of the motor 4, so that the inner circumferential surface 551 is in close contact with the outer annular surface 44, thereby making the air motor compact. The cover material is shocked due to the vibration generated by the work of the cylinder.
如圖3所示’該緊迫件5〇更包含一環狀凸塊％，該環狀 凸塊56自該第二抵靠Φ 53綱前殼體20延伸，且該環狀凸 塊56之輪廊為非圓形。本創作之較佳實施例中，該環狀凸塊 56包含—外周面’該外周面具有-第-平面561及一與該第 一平面相對應之第二平面562，該第一平面561及該第二平面 562分別與該第二抵靠面兄垂直且該第一平面56ι與該第 一平面562相互平行，於其他實施例中，該環狀凸塊％的外 周面亦可為多角形（例如六角形），藉此，該環狀凸塊56可供 一工具套設，並藉由將該緊迫件50轉動並鎖緊於該主殼體10 上，令該氣動馬達40被壓迫的較緊實，使其蓋體43較不易被 震鬆。 由上可知’本創作之氣動卫具（四）不僅結構創新，且 具有顯著的進步功效，符合專利法相關規心爰依法提起專 利申明，輯柄早日辭料，實感德便。 【圓式簡單說明】 圖1係本創作較佳實施例之分解圖。 圖2係本創作較佳實施例之局部分解圖。 圖3係本創作較佳實施例之局部分解側視圖。 圖3A係緊迫件之另一視角示意圖。 圖4係本創作較佳實施例之局部圖，其中姆迫件螺設於 主殼體並緊迫該氣動馬達。 又、 【主要元件符號說明】 10 ： 主殼體 41 :心轴 11 ： 内壁 42 :汽缸 12 ： 第一固定段 43 :蓋體 13 ： 馬達容室 44 :外環面 14 ： 流量控制閥 5〇 :緊迫件 15 ： 扳機組 51 :穿孔 20 ： 前殼體 52 :第一抵靠面 21 ： 工具容室 53 .第二抵靠面 30 ： 工具組 54 :第二固定段 31 ： 工具頭 55 :環凸部 32 ： 轉動部 551 :内周面 M399005 321 33 ： 331 40 : :卡槽 56 :環狀凸塊 打擊塊 561 :第一平面 :孔洞 562 :第二平面 氣動馬達As shown in FIG. 3, the pressing member 5 further includes an annular projection 56 extending from the second abutting Φ 53 front housing 20, and the ring of the annular projection 56 The gallery is non-circular.
