[0026] The utility model is further described below in conjunction with the accompanying drawings. Example

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, a metal sheet circle gripping tool of the present embodiment comprises a fixed disk 6, a central axis 62 is arranged at the center of the fixed disk 6, a handle 1 which can make circular motion around the central axis 62 is hingedly connected to the central axis 62, and a sliding axis 4 is arranged on the handle 1; a plurality of positioning axes 5 are arranged on the fixed disk 6, and the distances of the plurality of positioning axes 5 relative to the central axis 62 are all consistent, and the plurality of positioning axes 5 are evenly distributed on the circumference of a circle set relative to the center of the fixed disk 6, and a fixed axis 8 for positioning the thin plate workpiece 7 is also arranged on the outer side of one of the positioning axes 5, and the position of the fixed axis 8 is set as the starting point of the circle gripping, and the sliding axis 4 of the handle 1 starts from this point, and the thin plate workpiece 7 is gripped into a circle while the handle 1 rotates around the central axis 62. In actual use, the thin plate workpiece 7 can also be round steel or other similar parts that need to be gripped into a circle.

[0028] The distance between the sliding shaft 4 and the center axis 62 is the sum of the distance between the positioning shaft 5 and the center axis 62 and the wall thickness of the thin plate workpiece 7, that is, when the sliding shaft 4, a positioning shaft 5, and the center of the fixed disk 6 are located on the same straight line, the distance between the outer wall of the sliding shaft 4 and the outer wall of the positioning shaft 5 is the wall thickness of the thin plate workpiece 7. When the handle 1 rotates along the center axis 62, the sliding shaft 4 can smoothly grip the thin plate workpiece 7 in a circle.

[0029] like Figure 3 As shown, a central axis sleeve 2 rotatably matched with the central axis 62 is provided at the end of the handle 1, so that the handle 1 can smoothly perform a circular motion with the central axis 62 as the center.

[0030] like Figure 3 and Figure 5 As shown, a sliding shaft sleeve 3 is provided on the outside of the sliding shaft 4. The distance between the sliding shaft sleeve 3 and the central axis 62 is the sum of the distance between the positioning shaft 5 and the central axis 62 and the wall thickness of the thin plate workpiece 7. In actual use, the sliding shaft sleeve 3 contacts the thin plate workpiece 7. When the circle is gripped, the sliding shaft sleeve 3 rotates relative to the sliding shaft 4 to reduce friction (equivalent to converting sliding friction into rolling friction).

[0031] like Figure 6 As shown, the central shaft 62, the sliding shaft 4, the positioning shaft 5 and the fixed shaft 8 have the same structure, and all include a shaft body 41 and a threaded portion 42 arranged at the end of the shaft body, and a nut 43 for fixing is screwed onto the threaded portion 42.

[0032] like Figure 4 and Figure 5As shown, the handle 1 is provided with a first adjusting groove 11 for the sliding shaft threaded portion 42 to penetrate into. According to the required diameter of the grip circle, the threaded portion 42 can pass through any position of the first adjusting groove 11 and screw on the nut 43 for fixation. The end faces of the first adjusting groove 11 that cooperate with the shaft body 41 and the nut 43 are all set to be planes. Through the setting of the plane, the sliding shaft 4 can be better fixed when the nut 43 is screwed on.

[0033] like Figure 2 As shown, the fixed disk 6 is provided with a plurality of second adjustment grooves 61 for the threaded portion of the positioning shaft 5 to penetrate, and the positioning shaft 5 corresponds to the second adjustment grooves 61 one by one. According to the diameter size of the required grip circle, the positioning shaft 5 can pass through any position of the second adjustment groove 61, and the fixed shaft 8 can also be fixed in a second adjustment groove 61 at a certain position, and the position of the fixed shaft 8 is used as the starting point of the grip circle workpiece. A mounting hole (not shown in the figure) for fixing the central shaft 62 is provided at the center of the fixed disk 6. The fixing method of the positioning shaft 5, the fixed shaft 8, and the central shaft 62 is similar to that of the sliding shaft 4. After passing through the fixed disk 6, the nut 43 is screwed on the back thereof.

[0034] like Figure 2 As shown, the side wall of the second adjustment groove 61 is provided with scale lines, which can conveniently fix the positioning shaft 5 at a suitable position according to the preset diameter of the round workpiece.

[0035] When the utility model is in use, firstly, according to the diameter and the central angle of the workpiece to be gripped in a circle (such as a full circle or a semicircle), the positioning shaft 5 is installed at the designated position of the appropriate number of second adjustment grooves 61, and the fixed shaft 8 is installed at the positioning shaft 5 at the starting position, and the central shaft sleeve 2 of the assembled handle 1 is sleeved on the central shaft 62, the workpiece is passed through between the fixed shaft 8 and the positioning shaft 5 at that position, and the sliding shaft sleeve 3 of the handle 1 is rotated to the fixed shaft 8 and starts to rotate until the workpiece is gripped in a circle, which has the advantages of simple structure and easy use.
