[0033] Please see Figures 1 to 4 The integrated arc lock of this embodiment includes: a base plate 1; an arc lock body 2 mounted on the base plate 1 and having at least two sets of engaging and fixing holes; an arc positioning block 3 mounted on the arc lock body 2, having a guide hole and an internal thread formed on the guide hole; and a central shaft unit 42 mounted on one of the engaging and fixing holes, one end of which is engaged with a knob 41, and threaded through the guide hole to the lower end of the engaging and fixing hole group; and an arc block module 4 whose one end face abuts against an outer convex ring a1 formed on the central shaft unit 42, and has a plurality of positioning shafts c3 forming therethrough through the arc fixing block 3 and the positioning shaft unit 43 matching another engaging and fixing hole group. Specifically, the outer circumference of the outer convex ring a1 has an external thread matching the internal thread. When the knob 41 is rotated, the central shaft unit 42 rotates and presses down, and the positioning shaft unit 43 descends in conjunction with it until the positioning shaft c3 engages with the corresponding engaging and fixing hole group.
[0034] In a preferred embodiment, the arc lock body 1 forms a locking channel from the upper end inward, and the locking channel widens outward from the upper end to form a locking groove. One locking hole group is formed at the locking channel, and another locking control group is formed from the locking groove downward. Specifically, one locking hole group is the locking channel, which includes a threaded section and a locking positioning section. The diameter of the threaded section is smaller than that of the locking channel section, and a locking positioning ring for locking the central shaft unit 42 protrudes from the locking channel section. The locking positioning ring has several locking grooves formed at intervals. The other locking hole group includes several locking positioning holes formed from the locking groove inward at intervals. When the knob is rotated and pressed down, the positioning shaft c3 engages with the corresponding locking positioning hole.
[0035] In a preferred embodiment, a groove 31 is formed on one end face of the arc positioning block 3, a guide hole is formed in the groove 31, and a plurality of locking holes 32 are formed at intervals in the groove 31 and beside the guide hole.
[0036] The central shaft unit 42 includes: a sleeve b1 disposed on the snap-fit fixing channel, one end snapped and fixed to the knob 41 and the other end snapped to the snap-fit positioning ring; a central shaft b2 passing through the sleeve b1, one end fixed to the sleeve b1 and the other end having an external thread formed on its outer side; and an elastic element b3 sleeved on the outer periphery of the central shaft b2; the elastic element b3 is disposed within the snap-fit fixing channel section. Specifically, the lower end of the sleeve b1 has a plurality of protruding snap-fit portions b11 with gaps formed on its outer periphery, one end of the central shaft b2 has a nut formed, and the threaded portion at the other end is directly smaller than the diameter of the central shaft section in the middle.
[0037] The positioning shaft unit 43 includes: a circular ring plate c1 with a through hole formed in the middle; a plurality of engaging plates c2 that are intermittently protruding on the circumference of the through hole and abutting the lower end face of the outer convex ring a1; and a plurality of positioning shafts c3 that penetrate the circular ring plate c1, with one end penetrating the arc positioning block 2 and the other end protruding on the other side of the circular ring plate c1 corresponding to the engaging positioning hole.
[0038] As can be seen from the above description, in this utility model, when the knob 41 is rotated to adjust the curvature, the lower end of the central shaft b2 rotates and presses down. At the same time, the sleeve b1 rotates and presses down in conjunction with the knob 41. When the outer convex ring a1 descends to screw into the groove 31 of the curvature positioning block 3, the curvature positioning block 3 applies a downward force to the positioning shaft unit 43, and the positioning shaft c3 faces the locking positioning hole, thereby achieving the effect of simultaneously adjusting the curvature and locking. Reversing the rotation of the knob 41 will reset the corresponding component in the opposite direction.
[0039] The structural design of this utility model enables the product to achieve arc adjustment and locking in one operation. The reasonable and effective structural design improves work efficiency.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
