Detailed Description
The present utility model will be described in further detail by way of examples with reference to the accompanying drawings, which are illustrative of the present utility model and not limited to the following examples.
The embodiment of the utility model comprises a screw rod 1, a slide rod 2, a first fixing piece 3, a slide sheet 4, a spring 5, a wheel 6, a second fixing piece 7 and a screw 8.
Two mounting holes are formed in the first fixing piece 3 in an up-down mode, the mounting hole in the upper portion is a square hole, the mounting hole in the lower portion is a round hole, and a rolling bearing is arranged in the round hole and used for mounting the screw rod 1. The number of the first fixing sheets 3 is two, and the first fixing sheets are oppositely arranged.
A screw 8 is mounted on the first fixing piece 3.
The middle part of the screw rod 1 is provided with silk threads, the two sides of the screw rod are provided with smooth round tubes, and the part of the screw rod is square. The screw rod 1 is rotatably arranged in the lower mounting hole of the two fixing sheets one 3, so that the screw rod 1 is rotatably arranged on the two fixing sheets one 3.
The two ends of the slide bar 2 are square, and the middle part is a smooth round tube. The two ends of the slide bar 2 are respectively and fixedly arranged in the upper mounting holes of the two fixing sheets I3, so that the two ends of the slide bar 2 are respectively and fixedly arranged on the two fixing sheets I3. The slide bar 2 and the screw rod 1 are arranged side by side up and down.
The upper portion of gleitbretter 4 is provided with the connecting hole, and the connecting hole is the circular hole, and the lower part of gleitbretter 4 is fixed with screw-nut. The slide bar 2 is sleeved in the connecting hole in a sliding way, so that the slide sheet 4 is in sliding connection with the slide bar 2. The screw rod nut is sleeved on the screw rod 1.
The spring 5 is sleeved on the slide bar 2, one end of the spring is propped against the fixed piece 3, and the other end is propped against the slide sheet 4.
The second fixing piece 7 is arranged beside the first fixing piece 3, a round hole is formed in the second fixing piece 7, and a rolling bearing is arranged in the round hole and used for installing the end part of the screw rod 1. One end of the screw rod 1 extends out of the first fixing piece 3 and then is connected with a rolling bearing in a round hole of the second fixing piece 7, so that one end of the screw rod 1 extends out of the first fixing piece 3 and then is rotationally connected with the second fixing piece 7. A screw 8 is also mounted on the second fixing piece 7.
The wheel 6 is positioned between the second fixing piece 7 and the first fixing piece 3 and is fixedly arranged on the screw rod 1.
