[0038] Specifically, please refer to Figure 3 and Figure 4The clamp head 120 can include a housing 121, a functional column 122, first and second clamping rods 123 and 124, first and second connecting rods 125 and 126, the housing 121 defines a mounting cavity 1212 in the housing 121, the housing 121 includes opposite extension and functional ports 1211; the functional column 122 is arranged in the functional port 1211 and can move along the extension direction of the functional column 122, the functional column 122 includes a guide section 1222 and an extension section 1221 connected to each other, and the extension section 1221 is close to the extension port; the first and second clamping rods 123 and 124 are arranged in the extension port respectively, and the first and second clamping rods 123 and 124 are rotationally connected to the housing 121; one end of the first connecting rod 125 is rotationally connected to the first clamping rod 123, and the other end is rotationally connected to the extension section 1221; one end of the second connecting rod 126 is rotationally connected to the second clamping rod 124, and the other end is rotationally connected to the extension section 1221.
[0039] The functional column 122 includes a first position (for example, the position of the functional column 122 shown in Figure 1 ) and a second position (for example, the position of the functional column 122 shown in Figure 2 ), and the functional column 122 can move between the first position and the second position; when the functional column 122 is in the first position, the guide section 1222 is located outside the housing 121, the extension section 1221 is located in the mounting cavity 1212, and the first and second clamping rods 123 and 124 form a clamping gap therebetween, and the cross intersection of the main rib and the longitudinal rib can be clamped into the clamping gap; when the functional column 122 is in the second position, the guide section 1222 and the extension section 1221 are both located in the mounting cavity 1212, and the first and second clamping rods 123 and 124 can clamp the cross intersection of the main rib and the longitudinal rib.
[0040] In this way, by adjusting the movement of the functional column 122 between the first position and the second position, the clamping of the cross intersection of the main rib and the longitudinal rib can be controlled, and the process of manual binding and clamping is replaced, which greatly improves the construction efficiency, reduces the labor intensity, and improves the construction safety.
[0041] In some embodiments of the present application, please continue to refer to Figure 1 and Figure 2 , the first and second clamping rods 123 and 124 are symmetrically arranged about the central axis of the functional column 122, so that by symmetrically arranging the first and second clamping rods 123 and 124, the stability of the rotation of the first and second clamping rods 123 and 124 during the movement of the functional column 122 between the first position and the second position can be ensured, and the stability of the overall structure can be ensured.

[0044] Specifically, please continue to refer to Figure 1 and Figure 2 The clamp head 120 can further include a first rotating column 1201 arranged on the inner wall of the shell 121, the first clamping rod 123 is provided with a first rotating hole matched with the first rotating column 1201, and the first rotating column 1201 is arranged in the first rotating hole, so that the first clamping rod 123 can rotate around the first rotating column 1201 by arranging the first rotating column 1201.
[0045] The clamp head 120 can further include a second rotating column 1202, the first clamping rod 123 is provided with a second rotating hole located on the side of the first rotating hole away from the outlet, the first connecting rod 125 is provided with a third rotating hole, and the second rotating column 1202 is arranged in the second rotating hole and the third rotating hole. Thus, the second rotating column 1202 is arranged to realize the rotational connection between the first clamping rod 123 and the first connecting rod 125.
[0046] The clamp head 120 can further include a third rotating column 1203, the first connecting rod 125 is provided with a fourth rotating hole located on the side of the third rotating hole close to the functional column 122, and the extension section 1221 is provided with a fifth rotating hole, and the third rotating column 1203 is arranged in the fourth rotating hole and the fifth rotating hole. Thus, the third rotating column 1203 is arranged to realize the rotational connection between the functional column 122 and the first connecting rod 125.
[0047] Further, the second connecting rod 126 is provided with a sixth rotating hole, and the third rotating column 1203 is arranged in the fourth rotating hole, the fifth rotating hole and the sixth rotating hole, so as to realize the rotating connection between the first connecting column, the second connecting column and the function column 122.
[0048] It can be understood that the clamp head 120 can further include a fourth rotating column 1204, and the second connecting rod 126 and the second clamping rod 124 are rotatably connected through the fourth rotating column 1204.
[0049] The clamp head 120 can further include a fifth rotating column 1205, and the fifth rotating column 1205 is arranged on the inner wall of the shell 121.

[0050] In some embodiments of the present application, please refer to Figure 1 and Figure 2 In the direction in which the outlet is directed to the function port 1211, the outer wall of the guide section 1222 is inclined to the circumferential outer side of the guide section 1222, and the radial dimension of the end of the guide section 1222 away from the outlet is greater than the radial dimension of the function port 1211.
[0051] The guide section 1222 has a certain elasticity, and when the function column 122 is moved from the first position to the second position, the guide section 1222 is moved from outside the mounting cavity 1212 to inside the mounting cavity 1212. The guide section 1222 plays a guiding role, so that the guide section 1222 and the function port 1211 are elastically deformed to a certain extent, so that the guide section 1222 can pass through the function port 1211. When the guide section 1222 is located in the mounting cavity 1212, because the radial dimension of the end of the guide section 1222 away from the outlet is greater than the radial dimension of the function port 1211, the guide section 1222 cannot pass through the function port 1211, so that the function column 122 is maintained in the second position, thereby avoiding the function column 122 from returning to the first position from the second position, and ensuring the stability of the clamp head 120.
[0052] The guide section 1222 can further include an abutting surface 1224 away from the outlet.

[0053] In some embodiments of the present application, please refer to Figure 1 and Figure 2, the function column 122 can include an auxiliary section 1223 connected with the guiding section 1222 away from one end of the outlet, the radial dimension of the auxiliary section 1223 is less than or equal to the radial dimension of the function port 1211, that is, the auxiliary section 1223 can pass through the function port 1211, and the staff can push the auxiliary section 1223 to realize the switching of the function column 122 from the first position to the second position.
[0054] In some embodiments of the present application, please refer to Figure 1 and Figure 2 The clamp head 120 can further include an elastic member 127 located in the mounting cavity 1212, one end of the elastic member 127 is in abutment with the shell 121, and the other end is in abutment with one end of the extension section 1221 towards the outlet, and the elastic member 127 always applies a pushing force to the function column 122 towards the function port 1211. Thus, by providing the elastic member 127, the stability of the function column 122 in the second position can be ensured, and the clamping effect of the clamp head 120 is not affected by the shaking of the function column 122 in the second position.
[0055] In some embodiments of the present application, please refer to Figure 1 and Figure 2 The inner wall of the shell 121 is provided with opposite first and second limiting plates 1281 and 1282, and the function column 122 is located between the first and second limiting plates 1281 and 1282. Thus, by providing the first and second limiting plates 1281 and 1282, the shaking of the function column 122 during movement between the first and second positions can be avoided, and the stability of the function column 122 during movement can be ensured.
