DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] In the description of the present invention, it should be understood that the terms "middle", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0028] In the present invention, unless otherwise clearly specified and limited, the terms "set", "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] like Figure 1 and Figure 2As shown, a ball flat steel clamp comprises a fixed jaw body 1, a movable jaw body 2 and a support frame 3, the support frame is arranged at the middle part of the upper end of the fixed jaw body, a first support 4 and a second support 5 are respectively arranged on both sides of the upper end of the fixed jaw body, the movable jaw body is located on one side of the first support, and the middle part thereof is rotatably connected with the first support through a rotating shaft 6, one side of the movable jaw body spans over the top of the fixed jaw body and is connected with a locking assembly for adjusting the rotation angle of the movable jaw body between the second support, a first limiting groove 701 is arranged at the lower end of one side of the fixed jaw body close to the movable jaw body, the first limiting groove cooperates with the second limiting groove 702 arranged at the lower end of one side of the movable jaw body, and forms a clamping cavity 7 matching the ball head shape of the ball flat steel, as shown in FIG. Figure 5 As shown, when in use, the ball head of the spherical flat steel is embedded in the clamping cavity, so that the spherical flat steel can be clamped, which is convenient for lifting, fixing, transferring and other operations.

[0030] like Figure 2 and Figure 3 As shown, the locking assembly includes a fixing hole provided on the second support, and the fixing hole is connected to the first positioning hole 201 and the second positioning hole 202 provided on the movable clamp body through a limiting member 8, and is used to lock the movable clamp body in the open and closed states of the clamping cavity, respectively. The limiting member is a bolt or a limiting pin. In this embodiment, the limiting member is a bolt to ensure the stability of the connection structure between the movable clamp body and the fixed clamp body. When the fixing hole is connected with the first positioning hole, the clamping cavity is in an open state, which is convenient for the embedding of the ball flat steel; conversely, when the fixing hole is connected with the second positioning hole, the clamping cavity is in a closed state, and the first limiting groove and the second limiting groove clamp and fix the two sides of the ball flat steel. In order to avoid wear on the ball flat steel during the use of the clamp, an elastic pad 12 is provided on the inner wall of the first limiting groove and the second limiting groove. The size of the clamping cavity can be slightly larger than the size of the ball head of the spherical flat steel. When the spherical flat steel is embedded in the clamping cavity, the elastic pad fits tightly with the spherical flat steel to achieve fixation. At this time, the web of the spherical flat steel fits in the first limiting groove, and the raised ball head is located in the second limiting groove.

[0031] like Figures 1 to 3 As shown, the bottom wall of the second limit groove is an inclined surface, and a prying steel head 13 is formed between the second limit groove and the bottom end surface of the movable clamp body. The vertical cross section of the prying steel head is a wedge. When the bulb flat steel is in a fallen state, the prying steel head can be used to pry it up from the bottom of the ball head side of the bulb flat steel to lift it off the ground for easy clamping of the bulb flat steel. For more convenient use, the prying steel head protrudes to the outside of the fixed clamp body. When the utility model is in a vertical state, the prying steel head is located below the horizontal plane where the lower end surface of the fixed clamp body is located.

[0032] Combination Figure 4As shown, the support frame is inverted U-shaped, and is assembled and connected to the fixed clamp body by bolts 9, which is convenient for disassembly and assembly. A lifting ring 10 and an operating rod 11 are provided on the support frame, and the operating rod is detachably connected to the support frame. A threaded hole 301 is opened in the middle of the top of the support frame, and the end of the operating rod is threadedly connected to the threaded hole. There are two lifting rings, which are symmetrically distributed on both sides of the operating rod. When the operating rod is connected, it is convenient to pry up, lift, flip, etc. the ball flat steel; conversely, after the operating rod is disassembled, the ball flat steel can be lifted by connecting the lifting ring to the lifting rope or hook of the lifting equipment.

[0033] The method of using the utility model is as follows:

[0034] First, rotate the movable clamp body 2 to move the first positioning hole 201 to the position of the fixed hole, and use the limiter 8 to lock and fix the two, and the clamping cavity 7 is in an open state. If the bulb flat steel 14 is in a fallen state, the operator holds the operating rod 11, and uses the prying steel head 13 to pry it up from the bottom of the ball head side of the bulb flat steel 14 and lift it off the ground, and then make the end of the web of the bulb flat steel close to the ball head contact with the inner wall of the first limiting groove 701, remove the limiter 8, rotate the movable clamp body 2, so that the ball head end of the bulb flat steel 14 is embedded in the second limiting groove 702, and then use the limiter 8 to lock and connect the second positioning hole 202 with the fixed hole, and the clamping cavity 7 will completely clamp the bulb flat steel, and finally use the operating rod 11 or the lifting ring 10 to perform subsequent operations as needed.

[0035] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
