Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

It is to be noted that unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the present invention belongs.

As shown in fig. 1 to 3: the novel clamp of the embodiment comprises a clamp sleeve 1 and a connecting piece 2 connected to an opening of the clamp sleeve 1; the clamp sleeve 1 is made by a strip shaped plate 11 and two connecting blocks 3, the strip shaped plate 11 is buckled into the cover form and both ends are at the reverse curling of opening part, two connecting blocks 3 are rolled up respectively inside the both ends of strip shaped plate 11, all be equipped with the connecting hole that is used for erection joint spare 2 on the curling part at 11 both ends of strip shaped plate and two connecting blocks 3, the both ends of strip shaped plate 11 are rolled up on connecting block 3, and support by connecting block 3, avoid taking place the deformation, the local stress of 11 both ends connecting hole departments of strip shaped plate can be eliminated after the two is fixed, avoid splitting in connecting hole department.

In this embodiment, two connecting blocks 3 are the semicylinder type to two connecting blocks 3 set up with the cambered surface is relative each other, and the dog-ear block of the edge of connecting block 3 and the 11 tip of bar shape board, sound construction.

In this embodiment, the connecting piece 2 is a bolt, the connecting hole of one connecting block 3 is a circular through hole, the connecting hole of the other connecting block 3 is a threaded hole screwed with the bolt, and the bolt penetrates through the circular through hole to be matched with the threaded hole in a screwed manner, so that locking is realized. The outer end face of the bolt head is provided with a hexagon socket 21 suitable for inserting a hexagon tool to screw the bolt.
