Description of the new type: [Technical field to which the new type belongs] A circular hole saw is fast This creation is related to the circular hole saw, especially the dismantling shaft. [Previous technique] 5-10 electric drills are inclined in the Lance group. You must use the assistance of your hand to control the electric power. — ^ 叫 向 However, since the chuck wrench is not integrated with the electric drill, the situation sometimes occurs, and it is very inconvenient for the chuck wrench to control the displacement of the chuck jaws. 'If the user must often replace the used _The second time of hole mining is to repeatedly reverse the chuck wrench, so that the electric drill changes the knife and the action becomes extremely time-consuming and troublesome. , 〃, 15 [New content] The main purpose of this creation is to provide a quick-release knife shaft for round-hole mines, which is simple and convenient to operate and allows the electric drill equipped with the quick-release knife shaft to quickly replace the used circle Hole saw. The reason is that, in order to achieve the purpose of unveiling, this creative department provides a 20-hole quick-release knife shaft for a round hole mine, which is installed in a circular hole saw and an electric drill, and the circular hole saw has a cymbal-shaped connecting piece. The body of the connecting piece is provided with an annular recess; and the quick-release knife shaft includes: a body, one end of which is connected with the electric drill, and the other end of the body has a set of connecting holes for receiving the connecting piece, and a A pivot hole, the inner wall of which is connected to one side of the sleeve hole; and a limit rod that can be slidably inserted into the pivot hole of the M263175 body, and one side of the shaft thereof extends into the recess of the connecting member, At the same time, the limit lever has a groove to be mated with the socket hole. When the limit lever is displaced so that the groove is mated with the socket hole of the body, the shaft of the limit lever exits the sleeve. Outside the connection hole, the connecting member can be pulled away from the body. 5 By this, installing the quick-release cutter shaft on the chuck of an electric drill, the electric drill can quickly replace the circular hole saw. [Embodiment] Please refer to the first figure, which is a schematic diagram of the combination of the quick-release knife shaft (10) 10 and the round hole mine (50) in the preferred embodiment of the creation. As shown in the figure, the round hole mine ( 50) It consists of a cylindrical connecting piece (51), a circular saw blade (52) screwed on one end of the connecting piece (51), and a drill bit (53) that can pass through the center of the connecting piece (51) Common composition 'wherein the cross-sectional shape of the body of the connecting piece (51) is hexagonal, and a through hole (511) is provided in the center along the axial direction for the drill (53) to pass through, and the connecting piece 15 (51) The other end of the body is provided with a ring-shaped recess (512). However, the round hole mine (50) is a conventional technique. Here, only the link (51) related to this creation is described. Referring to the second and third figures, the quick-release knife shaft (10) of this creation mainly includes: a body (20), a limit rod (30), and an elastic element, and in this embodiment, the elastic element It is a torsion spring (40), where: 20 The body (20) has a barrel portion (21) and a rod portion (22) connecting the barrel portion (21) to the end, and the barrel portion (21) The other end is recessed from its center to form a socket hole (211) extending along its axial direction. The cross-sectional shape of the socket hole (211) is a hexagonal shape that matches the cross-sectional shape of the connecting member (51). A pivot hole (212) is opened from the body portion of the barrel portion (21). The two ends of the pivot hole (212) are open to the air, and the middle portion is on the M263175 side and communicates with the socket hole (211). With reference to the fourth and fifth figures, the limit lever (30) is slidably disposed in the pivot hole (212) of the body (20), and one side of the shaft of the limit lever (30) (3ι) and extended into the socket hole (2Π) of the 4 body (20), and the middle section of the side (31) is provided with a 5 groove (32), and when the limit rod (30) is displaced, the When the groove (32) is opposite to the socket hole (211), the shaft of the limit lever (30) is pulled out of the socket hole (211). One end of the torsion spring (40) is connected to one end of the limit rod (30), and the other end is provided on the barrel portion (21) of the main body ，, so the torsion spring (4〇) is used. ) The torque provided by 10 drives the limit lever (30) to a latching position (as shown in Fig. 3) 'and blame the elastic return force for displacement toward the latching position. With the above structure, when installing, the body (20) is first connected to the chuck (not shown) of the electric drill with its rod part p⑺, and then the user pushes the vertical rod (30) with his finger. ) Method, the limit lever (30) is driven to slide, and when the limit talent (30) is moved to its groove (32) and the socket hole pH of the body (2〇), it is about to The connecting piece (51) is inserted into the inner opening of the socket hole (211) of the body (20), ^ the recess (512) of the connecting piece (51) and the pivot hole (212) of the body (20) In the relative time, the user can release the hand pressed on the limit lever 此时. At this time, under the influence of the returning force of the torsion spring (40), the limit set moves, and its shaft-side ⑼ Will again extend into the connecting piece (= 512), and combine the connecting piece (51) with the body (20); when disassembling and disassembling, 'the user presses the limit lever 手 by hand, so that The groove (32) of the limit lever 与 and the connecting piece (51) are bribed, and the shaft of the lever ⑽ will withdraw from the socket hole (Sichuan) of the body (20). At this time, 'use Then, the connector (51) of M263175 can be pulled away from the body (20). Therefore, the quick-release knife shaft of this creation can be easily and easily operated, quickly assemble the circular hole saw on the quick-release knife shaft, or quickly remove the circular-hole saw from the quick-release knife shaft. The electric drill equipped with the quick-release cutter shaft can achieve the main purpose of quickly replacing the circular hole saw.
