The fixed block 1221 and the main gripping arm 122 may be integrally formed or welded.
Of course, in other embodiments of the present utility model, the main gripping arm 122 may be directly supported by the support bar 132 without the fixing block 1221.
Referring to fig. 6, the fixed block 1221 is concave, the fixed block 1221 is relatively provided with a first inner groove 1222 and a first outer abutting surface 1223, the supporting rod 132 is connected to the first inner groove 1222 through the latch 133, and the first outer abutting surface 1223 contacts the main gripping arm 122.
In the above technical solution, on one hand, the overall structural strength of the supporting rod 132 and the fixed block 1221 can be improved, so as to avoid the supporting rod 132 from being bent by the main gripping arm 122; on the other hand, the first inner groove 1222 may have a certain limiting effect on the supporting rod 132, so as to prevent the supporting rod 132 from easily disengaging from the first inner groove 1222.
And, when the bolt 133 is used to connect the first inner groove 1222 and the supporting rod 132, the supporting rod 132 and the first inner groove 1222 are provided with a through hole for accommodating the bolt 133, and the bolt 133 is used to connect the first inner groove 1222 and the supporting rod 132, so that the dismounting process can be faster.
Of course, in other embodiments of the present utility model, the support rod 132 and the first inner groove 1222 may be removable by a threaded connection.
Referring to fig. 6, the support bar 132 has a U-shaped cross section. The cross section of the support rod 132 may be understood as a cross section perpendicular to the axial extension direction of the support rod 132, and by defining the cross section dimension of the support rod 132, the support rod 132 may have better structural strength and rigidity while having less material.
Referring to fig. 6, the mounting block 131 is also concave, the mounting block 131 is relatively provided with a second inner groove 1311 and a second outer abutting surface 1312, the second outer abutting surface 1312 is connected to the frame 110, and the supporting rod 132 is hinged to the second inner groove 1311.
By providing the second inner groove 1311, when the support rod 132 does not support the fixed block 1221 and the support block naturally falls under the influence of gravity, the support block can move in the second inner groove 1311, and the support block and the second inner groove 1311 are not mutually infected, so that the upper side of the mounting block 131 is avoided.
The foregoing is merely illustrative of the present utility model, and the present utility model is not limited thereto, and any changes or substitutions easily contemplated by those skilled in the art within the scope of the present utility model should be included in the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
