Description

Technical Field

[0001] The utility model relates to a horizontal sliding window, in particular to a connection structure between a handle and a push rod of the horizontal sliding window. Background Art

[0002] At present, the existing sliding windows are provided with a handle on both sides of the sliding windows. The two independent handles are used to push the sliding windows outward to open or to close them inward to lock them. The gripping parts of the handles of the two handles are connected by a push rod. When the sliding windows are pushed outward or closed inward, the push rod can be pushed to drive the two handles to move synchronously to open and close the windows. The gripping parts of the handles and the push rod are usually fixed together in the form of threaded connection. Since there are many uncertainties in on-site installation, the conventional operation is that the installer cuts the push rod of the required length on the spot according to the specific size, cuts it and then taps it. Cutting requires corresponding cutting tools, and tapping requires corresponding tapping tools. The operator needs to carry many auxiliary tools, which makes the overall operation more troublesome.
