[0027] The technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are used only for explaining the utility model, and cannot be understood as limiting the utility model.

[0028] A multi-cam continuously driven escapement mechanism, such as Figures 1-4 As shown, the escapement includes an escape fork 1 and an escape wheel 2. The escape wheel 2 includes a toothed body 201 with toothed grooves 203 on its outer side. Multiple sockets 205 are inserted into the toothed grooves 203, and cam blocks 204 are mounted on the top of the sockets 205. Multiple screw holes 202 are formed on the outer surface of the toothed body 201, the number of which is the same as the number of sockets 205. Bolts 206 are installed in the screw holes 202. This structural design allows the cam blocks 204 on the escape wheel 2 to be flexibly connected to the toothed body 201 via the sockets 205, achieving the replaceability of the cam blocks 204 and facilitating quick replacement of cam blocks 204 of different shapes or sizes according to different needs. Simultaneously, the cooperation of the screw holes 202 and the bolts 206 ensures the stable installation of the sockets 205 and the cam blocks 204, improving the reliability and durability of the escapement mechanism.

[0029] See Figure 1 , Figure 4 Bolt 206 passes through socket 205 and is used to secure socket 205. A hexagonal hole 207 is provided on the outer surface of bolt 206. The design of bolt 206 passing through socket 205 enhances the connection strength and ensures the secure mounting of socket 205 on toothed body 201. The hexagonal hole 207 provides a convenient tightening method, allowing maintenance personnel to easily tighten or loosen bolt 206 using a hex wrench, improving maintenance efficiency and convenience.

[0030] See Figure 3 , Figure 4 The hexagonal hole 207 connects to an external hexagonal wrench, allowing for the tightening of bolt 206. This perfect fit between the hexagonal hole 207 and the hexagonal wrench ensures a more precise and reliable tightening process for bolt 206. This design not only improves tightening efficiency but also reduces the risk of loosening or damage to parts due to improper tightening, further guaranteeing the stable operation of the escapement mechanism.

[0031] See Figure 1 , Figure 2 The socket 205 and the cam block 204 are arranged in a circular array at equal intervals. This circular array design makes the distribution of the cam block 204 on the escape wheel 2 more uniform. This not only improves the balance and stability of the escapement mechanism, but also makes the power transmission smoother and more uniform. At the same time, this design also facilitates the debugging and maintenance of the escapement mechanism, reducing the difficulty of maintenance.

[0032] See Figure 1, the escapement fork 1 includes a main shaft 101, the top of the main shaft 101 is provided with a fork head 104, the main shaft 101 serves as the support core of the escapement fork 1, providing a stable rotating basis. The design of the fork head 104 enables the escapement fork 1 to make precise contact with the tooth tip or cam block 204 of the escapement wheel 2, achieving effective power transmission and accurate execution of the escapement action. This structural design improves the accuracy and reliability of the escapement mechanism.

[0033] Referring to Figure 1 , the bottom of the main shaft 101 is provided with a first fork body 102 and a second fork body 103 on both sides, respectively, and the symmetrical design of the first fork body 102 and the second fork body 103 enhances the balance and stability of the escapement fork 1. This structure enables the escapement fork 1 to maintain a uniform stress state during rotation, reducing vibration or deviation caused by uneven stress. At the same time, the design of the two fork bodies also provides more contact points, making the escapement action more reliable and stable.

[0034] Referring to Figure 1 , the first fork body 102 and the second fork body 103 can respectively contact the cam block 204, and the contact design of the first fork body 102 and the second fork body 103 with the cam block 204 achieves accurate escapement action of the escapement mechanism. This contact method enables the escapement fork 1 to rotate and swing accurately according to the profile shape of the cam block 204, thereby achieving accurate power transmission and precise execution of the escapement action. This design improves the sensitivity and accuracy of the escapement mechanism, making the entire mechanism more reliable and efficient.

[0035] The implementation principle of the embodiment is: first, since the cam block 204 and the tooth body 201 are connected through the socket 205 and the bolt 206, when the cam block 204 is damaged or worn, the cam block 204 can be replaced individually without replacing the entire escapement wheel 2, which greatly reduces maintenance costs and waste;

[0036] The outer surface of the bolt 206 is provided with a hexagonal hole 207, which facilitates tightening and loosening operation with a hexagonal wrench, and this design makes the maintenance process simpler and more efficient, improving the maintenance efficiency.
