Description of the Invention: [Technical Field] The present invention relates to a differential n-locking device, and more particularly to a convex ring having a radial perforation and a concave shaft by a differential Innovative locking device designed by a groove and a ring made independently - 冋 离 [Previous technology] According to the 'differential device', also known as differential II, it is commonly used in tire transmission structures of vehicles. On the 'Because the vehicle is over material, the left and right tires are different from each other. Therefore, the number of turns of the left and right tires will be different, and in this case, the left and right tires can be achieved by the combination of the differential devices. It produces the reverse direction operation, that is, the "differential effect"; when the differential is used, it must be switched by the locking device due to the switching of the same direction and the reverse rotation mode of the two-wheeled rod involving the coaxial core line. Its active state; most of the current differentials use electromagnetic clutch devices as a way to lock and release the shaft; however, such electromagnetic clutch devices have found in their extensive application experience that their locks are The action between the release is often due to the instability of the electromagnetic force, and the correctness of the action of the shirt is relatively strong. In terms of the locked state, it is more likely to cause serious problems of insufficient stability or even disengagement; based on this, although the follow-up is directed to this The shortcomings have developed a mechanical differential (four) device, but the problem is that the structure is too complicated, the cost is high, and the maintenance is inconvenient, which is not practical. 疋x For the above, how to develop a more practical and useful The difference is that the industry needs to think about the breakthrough. In view of this, the inventor has been engaged in the manufacturing development and design experience of related products for many years, and the needle 1275502 has been evaluated for the above objectives, _ design and amount. - The present invention is embodied in a practical manner. [The present invention] The main object of the present invention is to provide a differential device, in which a main = 3$ group is provided on a convex ring edge outside the center of the main flywheel perforation, and a bell hole on the edge of the convex ring, and a plurality of grooves at the end of the shaft of the pie, which are opposite to the radial perforations on the convex heave when the main shaft is rotated to the pre-twist angle; and pivoted to the convex ring The ball-shaped bead body is pinched to the perforation; the clutch seat is pivoted on the main shaft to be axially displaceable, and the center of the main hole of the sleeve 2 is the main flywheel - the Qing Cheng Lai section and the Jujue section, the small section The miscellaneous fits with the outer edge of the convex ring, and the outer shoulder of the small expanded groove section is formed to be inwardly fixed to the inner side of the bead body. The limit of the ring surface when the ball body is outwardly tangled out of the groove. The mine is quickly set to light, and the 俾 can be easily built and the cost is reduced. The locking effect is particularly stable and practical. [Embodiment] In order to enable the reviewing committee to have a better understanding and understanding of the purpose, features and effects of the present invention, please refer to the following [simplified description of the drawings] as follows: First, see 第1 2 and 3 are a preferred embodiment of the differential locking device of the present invention, the locking device being assembled on the main flywheel (11) and the main shaft (2 0) of the existing differential (丄〇). - between the ends, wherein one end of the main shaft (2 〇) pivots out of the outer side of the central perforation (i 2) provided by the main flywheel (11); The feature system includes: a convex ring edge (1 3 ) disposed outside the center perforation (1 2 ) of the main flywheel (1 1 ); and a plurality of spaced apart openings on the convex ring edge (1 3 ) a radial perforation (1 4 ); and a plurality of grooves (2 1 ) arranged in a circumferential direction at the end of the main suction cup (20), the grooves being axially extending And the grooves are opposite to the radial perforations (14) on the convex ring edge (13) when the main shaft rod (2 〇) is rotated to a predetermined angle; and the 1275502 bead convex j (1 3) radial a beaded body (30) of perforated (1 4), which can be immersed in the groove (2 D) on the face (穿孔4) and the (4) (2丨) of the bar (2 Q) In the middle, the ball body (3 ◦) is located at the same time in the radial perforation ((4) == 卜定轴杆杆 (2 Q ) (as shown in Figure 3; otherwise, when the ball body is completely out of the groove (2 1 When it is formed, the main shaft (20) is released from 0), and it is in the shape of a ring. It is sleeved on the main shaft (2 0) - the outer circumference of the end is driven to be axially displaced and retracted. Wearing a sleeve hole (4 1 ) toward the segment (4 3 ), wherein the small expansion slot segment 4 2) The aperture is exactly the same as the convex ring = == When the small expansion slot section (4 2 ) stands on the outer circumference of the radial perforation (14) of the convex collar (13), the ball bead (3 〇) Internal fixation, the large expansion section (4 Γϊ groove section (4 2), is used as the limit torus when each ball body (3 Q ) is moved outwards out of the groove (21). With the above configuration, the operation of the differential lock device of the present invention is as follows. As shown in Fig. 3, the main shaft (20) is locked; when the clutch (40) is predetermined When the transmission is driven to the convex ring of the main flywheel (1丄), the small expansion (4 2 ) of the clutch seat (4 0 ) will be placed on the convex ^, thereby enabling the ball body ( 3 0) Inward gorge, that is, the ball and the k are located in the radial perforations (i 4) and the grooves to lock the main shaft (2 〇) as shown in Fig. 4, which is the main shaft (2 〇 The release state; when the departure seat 0) is scheduled to pass the pure qing _ to the far-end flywheel (i 2) square stop position, it will constitute the large expansion slot of the clutch seat (4 〇) (4 3 > 3) radial perforation (1 4) in the state of the outer circumference, such that the main shaft (2 〇) ' '' the bead (30) has a space that can be displaced outward, and the rat does not fix when 'by = the main shaft Release the state.卞v d u ) ′ [Advantages of the invention] 1275502 1 The differential locking device only has a convex collar Q 3 ) with a radial perforation, a spindle f ( 2
