The handle 2 is an auxiliary device provided by a preferred embodiment of the present invention. The handle is mounted on the air-powered or power tool profile. The red display only shows the appearance of the front section of the body (25). Wheel (50) ^bar hand (10) has a handle (30), a bundle of rings (40) and a front end of the pressing member is a contact portion (32) corresponding to the body contour of the power tool to contact The body (25); the outer end of the handle is for holding. ΐ Γ Γ Γ Γ 为 为 为 Γ 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为The two end members (45)' of the looper can be screws, locks or rivets, and this embodiment is a screw 4. The connecting component is threaded through the through hole (four) of the first end (42) of the bundle ring (10) and screwed to the screw hole (34) of the handle (30) side, as shown in the fifth figure, (42) is fixed to the grip Handle (30) side. t # π The pressing member (50) has a -butt (10) and an I-tighter _. The inner end (54) of the post (52) is a screw end provided with a beak, and one end of the tightening button is a cam end (62) having a cam action and the other end is a toggle end. The hole (621) of the cam end (62) of the tightening base is pivoted to the outer end (55) of the post (52) by the -axis (66), and the miscellaneous (66) is the rotating towel recording lever. Upward i The circumferential surface of the cam end (4) has a positioning point '--release portion (4) and - pressing portion 7 (64). The distance of the release portion (63) from the center of rotation of the tightening button (i.e., the axis (66)) is known to be longer than the distance from the center of rotation of the pressing portion (64). In addition, the cam end (62) is composed of two juxtaposed lugs (67), as shown in the seventh figure, and a space (68), a release portion (63) and a pressing portion are formed between the two lugs. (64) The peripheral surface of the lug (52) is formed by the outer end of the post (52) extending into the space (68) between the two lugs (67) and pivotally connected to the cam end (62). The two sides of the triggering end (65) are each provided with a fin (69) on the same side of the pulling end. The pressing member (50) penetrates the through hole (44) of the second end (43) of the collar (40) with the screw end (54) of the post (52), and is screwed to the handle (3). 〇) The other side of the screw hole (35) 'as in the fifth figure' and the post (52) into the handle (3 〇) the appropriate depth. Thereby, the second end (43) of the collar is in a substantially connected relationship with the grip via the pressing member. When the invention is used, the collar (3) of the auxiliary handle (20) is looped on the ring groove (26) of the surface of the body (25) (as shown in the third figure), and then, as shown in the second and sixth figures, When the tightening button (60) of the pressing member (50) is turned toward the grip (3〇), the pressing portion (64) of the cam end (62) of the tightening button (6〇) can be brought into contact with the bundle. The second end (43) of the ring (3〇). Since the pressing portion (64) has a longer radial distance from the shaft (66), the pressing portion presses the second end (43) of the collar (30) toward the grip (3〇), so that the collar The circumference of the body is reduced and tightened to the body of the power tool (25) 'The auxiliary handle (20) is bundled with the power tool for holding. In the tightened state, the pulling end (65) of the tightening button (6〇) is moved to the grip (30), and the two flaps (69) are overlaid on the outer circumference of the grip. β When the user wants to adjust the angular position of the auxiliary handle, the bundle ring (3〇) must first be released to tighten the state of the power tool. As shown in the seventh and eighth figures, the user pulls the tightening button (5〇) outward from the pulling end (65), so that the pressing portion (64) leaves the second end of the collar (3 (7) ( 43), in turn, the release portion (63) is in contact with the second end of the bundle ring. At this time, since the radial distance of the release portion (63) from the shaft (66) is short, the second end is The stalk of the bundle ring itself. After the circumferential expansion of the collar, it is tightened to the body (25). The user can rotate the entire auxiliary handle on the body, for example, moving the upper side or the other side of the body. After the auxiliary handle is moved to the desired position, the 哕 tightening button (60) is re-pulled to the tightening position of the second and sixth figures, and the forced portion (64) is again pressed against the collar. At the two ends, the circumference of the collar is reduced and the machine is tightened (25).
