[0042] Referring to Figures 1-5 A dual-purpose telescopic spike, the telescopic spike 10 is connected with the pipe 20; the telescopic spike 10 includes a first spike 110 and a second spike 130;

[0043] The first spike 110 is rotatably arranged relative to the pipe 20, and is hollow inside and open at the upper and lower sides to form a through cavity 100.

[0044] The second spike 130 is movably arranged in the through cavity 100.

[0045] The first spike 110 is in transmission cooperation with the second spike 130, and when the first spike 110 rotates forward or reversely, the second spike 130 can be driven to move upward or downward.

[0046] The first spike and the second spike arranged in the utility model, in the normal state, the first spike is adhered and supported with the bottom surface. When it is needed to switch the spike for the ground, under the action of rotating the first spike, the second spike can be driven to stretch downward, so that the second spike protrudes downward relative to the first spike, thereby supporting the ground. The existing advantages are that any spike does not need to be disassembled, the loss of the spike is avoided, and the user operation is facilitated, and the needs of the user are met.

[0047] The second spike 130 moves upward or downward, and the action is that when moving downward, the second spike moves to a position protruding downward relative to the first spike, and the protruding part of the second spike relative to the first spike can contact the ground to form support. When moving upward, the second spike moves to a position in which the first spike protrudes downward relative to the second spike, and in the position, the first spike is adhered and supported with the ground.

[0048] Referring to Figure 5 , the telescopic spike 10 further comprises a guide base body 120, the guide base body 120 is provided with a guide groove 121 extending upward and downward, the second spike 130 is provided with a guide block 133, and the guide block 133 is movably inserted into the guide groove 121. The cooperation of the guide block 133 and the guide groove 121 can effectively constrain the upward and downward movement of the second spike 130, and the second spike 130 cannot rotate relative to the guide base body 120.

[0049] Further, the guide block 133 is threadedly connected with the first spike 110. When the first spike 110 is rotated, under the action of the threaded connection, the guide block 133 and the second spike 130 are driven to move upward or downward.

[0050] Referring to Figure 3 and Figure 5The first cleat 110 comprises a first cleat body 111 and a rotating sleeve 112 connected with the first cleat body 111, the second cleat 130 and the guide base 120 are arranged in the rotating sleeve 112, and the rotating sleeve 112 is threadedly connected with the guide block 133; the first cleat body 111 or the rotating sleeve 112 is arranged in rotation relative to the pipe 20. When the position of the second cleat is adjusted, the user rotates the first cleat body 111 in the forward direction or the reverse direction to synchronously drive the rotating sleeve 112, and the rotating sleeve 112, when rotating, drives the guide block 133 to move upward or downward relative to the guide groove 121 through the thread cooperation, so as to drive the second cleat 120 to move.

[0051] Further, the first cleat body 111 is designed in a "ring shape", which is to enable the second cleat 120 to move up and down freely without interference.

[0052] Referring to Figure 3 Further, the first cleat body 111 is designed in a "ring shape", which is to enable the second cleat 120 to move up and down freely without interference.

[0053] The mounting base 150 is designed in a ring shape, which is to enable the rotating sleeve 112 and the guide base 120 to extend into the mounting base 150 for connection.

[0054] Further, the guide base 120 is fixedly connected with the mounting base 150, and the connection mode is that the upper end of the guide base 120 is threadedly connected with the mounting base 150, and then the guide base 120 is fixedly connected with the mounting base 150 through glue dispensing.

[0055] Further, the guide base 120 is designed in a cylindrical structure, and the second cleat 130 is arranged in the guide base 120 to move up and down. The cylindrical structure is to enable the second cleat 130 to be arranged in the guide base 120 and move up and down in the guide base 120.

[0056] Referring to Figure 3 and Figure 4 The lower end of the second cleat 130 is provided with a downwardly extending plug-in part 134. The plug-in part 134 can be inserted into the ground during actual use to improve the support.

[0057] Referring to Figure 3 The second cleat 130 is provided with an elastic positioning structure 140, and the guide base 120 is provided with a positioning groove 122.

[0058] When the second cleat 130 is in the extended state, the elastic positioning structure 140 is clamped into the positioning groove 122 to restrict the up and down movement of the second cleat 130 relative to the guide base 120. The elastic positioning structure 140 prevents the second cleat 130 from being retracted during use, thereby affecting the support stability.

[0059] Referring to Figure 3 and Figure 5 , in this state, the second cleat 130 is shown in the extended state.

[0060] The second cleat 130 is internally provided with a mounting cavity 135, and the side wall of the second cleat 130 is provided with a pin hole 132 in communication with the mounting cavity 135;

[0061] The elastic positioning structure 140 includes an elastic member 142 arranged in the mounting cavity 135, and the elastic member 142 is connected with a locking pin 141 which is movably inserted into the pin hole 132;

[0062] The elastic member 142 is used to apply a force to the locking pin 141 to drive the locking pin 141 to pass through the pin hole 132 and then be clamped into the positioning groove 122.

[0063] When the second cleat 130 is moved downward to the extended state, in this state, the locking pin 141 is clamped into the positioning groove 122, which can restrict the upward movement of the second cleat 130 to avoid the upward retraction of the second cleat 130 affecting the support stability. When the first cleat 110 is driven by an external force to retract the second cleat 130 upward, the external force can drive the locking pin 141 to be separated from the positioning groove 122 to achieve unlocking, so that the second cleat 130 can move upward.

[0064] Further, the elastic member 142 is a V-shaped elastic piece, and the locking pin 141 is connected to both ends of the V-shaped elastic piece.

[0065] In the utility model, the pipe 20 is a foot pipe of a tripod.

[0066] In some embodiments, as shown in Figure 6 and Figure 9 , the guide base 120 and the connecting base 150 are detachably connected, so that when the threaded connection between the guide block 133 and the rotating sleeve 112 fails, the guide base 120 and the connecting base 150 can be separated. When the two are separated, the guide base 120, the second cleat 130 and the first cleat 110 can be taken out downward relative to the connecting base 150. The connecting base 150 is fixed on the pipe 20 by gluing or other methods. The cleat part is separated from the pipe 20 for maintenance or replacement of a new cleat part.

[0067] In some embodiments, as shown in Figure 6 and Figure 9 shown, about the disassembly connection of the guide base 120 and the connecting base 150. The guide base 120 is connected with a connecting piece 123, and the connecting piece 123 is provided with a friction limiting block 124; the connecting base 150 is in a hollow cylindrical structure, and a friction fitting block 151 is arranged on the inner wall of the upper part of the connecting base 150. A through channel 152 is arranged in the connecting base 150 on the side of the friction fitting block 151.

[0068] When the guide base 120 and the connecting base 150 are connected and locked, the friction limiting block 124 is located on the upper side of the friction fitting block 151 and the two are in close contact with each other. Under the action, the friction fitting block 151 can constrain the friction limiting block 124 together with the guide base 120 from moving downward relative to the connecting base 150, so that the guide base 120 is kept in the connecting base 150. The friction limiting block 124 is assembled in the connecting base 150 with interference, and the friction limiting block 124 is in friction fit with the inner wall of the connecting base 150 or with the friction fitting block 151. The friction fit provides a rotation constraint force that can constrain the guide base 120 from rotating relative to the connecting base 150. The rotation constraint force > the engagement resistance of the threaded fit of the rotating sleeve 112 and the guide block 133. Thus, when the rotating sleeve 112 is rotated, the guide base 120 will not rotate relative to the connecting base 150, so that the rotating sleeve 112 is rotated, the guide block 133 together with the second spike 130 moves up and down relative to the guide base 120, realizing extension or contraction.

[0069] Further, about the friction fit, the interference fit of the surface and the surface can be adopted, and at the same time, some concave-convex textures can be arranged on the surface and the surface to increase the friction force, thereby increasing the constraint force.

[0070] In some embodiments, as shown in Figure 8 the lower part of the guide base 120 is provided with a docking operation part 125 for docking with a disassembly tool. In order to realize that when disassembling, the tool machine is docked with the docking operation part 125, and then an action force is applied, the action force > the rotation constraint force, the guide base 120 rotates relative to the connecting base 150, and when the friction limiting block 124 corresponds to the through channel 152, the guide base 120 can move downward relative to the connecting base 150, that is, the friction limiting block 124 moves downward along the through channel 152, so that the guide base 120 and the connecting base 150 are separated.

[0071] The basic principle and main features of the present application and the advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application.
