[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the present invention.
[0025] like Figure 1 、 Figure 2 、 Figure 5 and Figure 6 In an embodiment of the utility model, a universal handle that can be quickly replaced includes a handle body 1, wherein the handle body 1 includes a handle body 11, and the handle body 11 is longitudinally provided with a quick-change interface 15. The quick interface is a non-circular design, which can limit the rotation of the joint. The handle body 11 is laterally slidably installed with a button slider 3, and the button slider 3 is located at the quick-change interface 15 and is provided with a joint slot 33. The joint slot 33 is used for the clamping of the joint of the main body 6; an extrusion component is installed between the end of the button slider 3 located inside the handle body 11 and the handle body 11, and the extrusion component is used to rebound and squeeze the button slider 3, thereby realizing the clamping of the joint in the joint slot 33, and the handle body 11 is installed with a limit pin 2 for limiting the button slider 3, and the limit pin 2 is used to limit the button slider 3.
[0026] Figure 2 、 Figure 3 and Figure 5The extrusion assembly consists of a spring 4 and a guide pin 5, the spring 4 is sleeved on the guide pin 5, one end of the guide pin 5 is installed on the button slider 3, and the two ends of the spring 4 are respectively against the handle body 11 and the button slider 3; the handle body 1 is provided with a button slider guide groove 14 that cooperates with the button slider 3, and the handle body 11 is provided with a spring limiting groove 12 at one end of the button slider guide groove 14; the handle body 11 is provided with a limit pin mounting hole 13 for installing the limit pin 2, and the limit pin mounting hole 13 is communicated with the button slider guide groove 14, and the button slider 3 is provided with a limit pin groove 34 that cooperates with the limit pin 2 at the limit pin 2 hole.
[0027] Figure 3 、 Figure 4 and Figure 5 The button slider 3 is composed of a pressing portion 31 and a slider portion 32.
