[0004] In view of the problems of unstable water stop fixing mode and easy to cause engineering quality accidents or safety accidents, the utility model provides a water stop fastener, and the technical scheme is as follows: a main shaft is provided with a push sleeve on the outer surface, a fixed chuck is arranged at the end of the main shaft away from the push sleeve, a movable chuck is arranged on the main shaft, and a hand wheel is arranged at the end of the push sleeve away from the main shaft.
[0005] As a preferred scheme, the outer surface of the main shaft is further provided with a main shaft thread, the inner wall of the push sleeve is provided with a sleeve thread, and the main shaft and the push sleeve are threadedly connected through the main shaft thread and the sleeve thread.
[0006] As a preferred scheme, the cross section of the main shaft is capsule-shaped, a hole corresponding to the cross section of the main shaft is arranged on the movable chuck, and the movable chuck is slidably connected with the main shaft through the hole.
[0007] As a preferred scheme, an active gasket is further arranged between the push sleeve and the movable chuck, and the active gasket is slidably connected with the main shaft.
[0008] As a preferred scheme, the hand wheel is fixedly connected with the push sleeve through spokes.
[0009] As a preferred scheme, anti-skid lines are arranged on the opposite surfaces of the movable chuck and the fixed chuck.
[0010] As a preferred solution, a binding belt is sleeved between the movable clamp head and the fixed clamp head, and the binding belt is used to bind the fixed clamp head when the movable clamp head is fixed, so as to enhance the stability.
[0011] The utility model discloses the beneficial effects of:
[0012] The device fixes the movable clamp head and the fixed clamp head through the cooperation between the advancing sleeve and the main shaft, prevents the water stop belt from loosening due to vibration and causing accidents, reduces the probability of safety risks on the construction site, then binds the binding belt, further increases the effect of the device on fastening the water stop belt, and the device is good in adaptability and can adapt to water stop belts of various specifications without specification limitation.

[0020] The utility model will be further described in detail according to the drawings and specific embodiments.
[0021] Embodiment
[0022] As Figures 1-6 The utility model discloses a water stop belt fastening device, including main shaft 1, the outer surface of main shaft 1 is sleeved with advancing sleeve 2, and the one end of main shaft 1 away from advancing sleeve 2 is equipped with fixed clamp head 9, and main shaft 1 is sleeved with movable clamp head 5, and the one end of advancing sleeve 2 away from main shaft 1 is equipped with hand wheel 3.
[0023] Further, the outer surface of the main shaft 1 is also provided with a main shaft thread 8, and the inner wall of the advancing sleeve 2 is provided with a sleeve thread 7, and the main shaft 1 and the advancing sleeve 2 are threadedly connected through the main shaft thread 8 and the sleeve thread 7.
[0024] Further, the cross section of the main shaft 1 is capsule-shaped, the movable chuck 5 is provided with a hole corresponding to the cross section of the main shaft 1, and the movable chuck 5 is slidably connected with the main shaft 1 through the hole. The friction area between the capsule-shaped main shaft 1 and the circular advancing sleeve 2 is small, and compared with the circular main shaft 1, it is more labor-saving, has higher fixing efficiency, and is lighter.
