[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. Through the provided connecting piece, the joint can be directly turned. At this time, the sealing ball rotates in the spherical groove on the sealing ring to adjust the orientation angle of the joint, so that the joint can be connected to the inclined water pipe, that is, it can be installed to water pipes with different inclination angles, thereby improving installation adaptability.

[0014] 2. Through the provided limit leveling parts, the water meter body can be placed on the V-shaped frame. At this time, the supporting ring is attached to the sealing ring on the water meter body. At the same time, the limit plate is attached to the end face of the sealing ring and the rubber tray is attached to the bottom of the water meter body, so that the center of the water meter body can be located directly above the counterweight ball, so that the load-bearing shaft is driven to rotate under the gravity of the counterweight ball.

By rotating the threaded rod, the two sets of threaded sleeves will be driven to move toward each other synchronously, and then the clamping claws on the two sets of clamps will be driven to clamp on the water meter body, so as to fix the leveled water meter body, so that the water meter body can always remain level during the subsequent pipe installation, without the need for manual control, thereby further improving the convenience during installation.

[0015] 3. When the clamping jaws are clamped on the water meter body, the threaded rod continues to rotate to drive the clamping seat to move. The pull plate will press against the guide plate to prevent the clamping jaws from moving. At the same time, the spring body will deform to offset the moving force brought by the clamping seat. One of the sets of threaded sleeves that continues to move will drive the lower tooth plate to move, so that the two sets of tooth plates are driven toward each other by the gears, thereby driving the support plate to move, so that the roller on the support plate can move from the horizontal section of the support plate to the inclined section, and under the guidance of the inclined surface of the inclined section, the support frame is forced to slide down in the support seat under gravity, thereby driving the limit plate and the support ring on the support frame to move down and away from the water meter body, thereby ensuring that the limit plate will not hinder the connection during the takeover process.
