[0006] Preferably, a No. 1 screw hole is symmetrically provided at the rear end of the fixed shell, and a long hole is provided at one side of the front end of the fixed shell near the end.

[0007] Preferably, a No. 1 screw groove is provided at the front end of the No. 1 trapezoidal insertion rod, and the internal thread of the No. 1 screw groove is connected with a fixing screw that passes through the long hole.

[0008] Preferably, a rotary handle is provided at one end of the fixing screw away from the No. 1 screw slot, and an anti-loosening pad is provided on the outer side of the fixing screw.

[0009] Preferably, a No. 2 screw hole is provided on both sides of the fixing seat, an adjusting screw is connected to the internal thread of the No. 2 screw hole, and a steel ball groove communicating with the No. 2 screw hole is provided on both sides of the fixing seat.

[0010] Preferably, a steel ball is arranged inside the steel ball groove, and a spring is arranged between the steel ball and the adjusting screw.

[0011] Preferably, a No. 2 screw groove is provided at the front end of the fixing seat, and two groups of the No. 2 screw grooves are symmetrically arranged about the central axis of the fixing seat, and a No. 3 screw hole is provided inside the fixing seat between the two No. 2 trapezoidal grooves.

[0012] In summary, the utility model mainly has the following beneficial effects:

[0013] 1. The utility model is provided with a rotating handle, a fixing screw, a No. 1 screw groove, an anti-loosening pad and a long hole. Since the fixing screw is threadedly connected with the No. 1 trapezoidal plug rod through the No. 1 screw groove, the fixing screw can drive the No. 1 trapezoidal plug rod to be closely contacted and locked with the fixed shell through the anti-loosening pad by rotating the handle, so that the No. 1 trapezoidal plug rod can be positioned in the fixed shell, so that the No. 1 trapezoidal plug rod can be prevented from shaking in the fixed shell, and the anti-loosening pad can be used to prevent the fixing screw from loosening due to vibration, thereby increasing the stability of the latch mechanism during use. Since the No. 1 trapezoidal plug rod is slidably connected with the fixed shell through the fixing screw and the long hole, after loosening the fixing screw, the No. 1 trapezoidal plug rod can be moved inside the fixed shell by moving the handle, so as to improve the convenience of use.

[0014] 2. The utility model is provided with an adjusting screw, a No. 2 screw hole and a spring. Since the adjusting screw is threadedly connected to the fixing seat through the No. 2 screw hole, after the No. 2 trapezoidal plug rod is inserted into the fixing seat, the adjusting screw can be turned to push the spring to move and contract, and at the same time, the steel ball and the No. 2 trapezoidal plug rod, and the No. 2 trapezoidal plug rod and the fixing seat are tightly abutted and locked, so that the No. 2 trapezoidal plug rod can be prevented from shaking in the fixing seat, thereby increasing the stability of the latch mechanism during use;

[0015] To summarize, the latch mechanism can achieve close contact and locking between the No. 1 trapezoidal rod, the anti-loosening washer and the fixed housing through the cooperation of the rotating handle, the fixing screw, the No. 1 screw groove and the anti-loosening washer, so that the No. 1 trapezoidal rod can be prevented from shaking in the fixed housing. At the same time, through the cooperation of the adjusting screw, the No. 2 screw hole and the spring, the steel ball and the No. 2 trapezoidal rod, and the No. 2 trapezoidal rod and the fixed seat can be closely abutted and locked, so that the No. 2 trapezoidal rod can be prevented from shaking in the fixed seat, thereby realizing the locking and anti-shaking function of the latch mechanism.
