[0003] Therefore, based on the defects of the existing die shifting arm, the existing die shifting arm needs to be improved. SUMMARY

[0004] The utility model discloses a controllable folding joint structure which solves the defects of the existing die shifting arm, such as inconvenient folding.

[0005] To achieve the above object, the utility model is realized through the following technical scheme.

[0006] A controllable folding joint structure, comprising a pivot seat, a pivot shaft is installed between the upper part and the lower part of the pivot seat, a sleeve is fixed on the pivot shaft, a spiral limiting groove is formed on the outer surface of the sleeve, a lifting block is provided outside the sleeve, a positioning pin is provided through the lifting block, one end of the positioning pin is embedded in the limiting groove, and a handle is fixed outside the sleeve.

[0007] Further, a connecting block is pivotally arranged on the pivot shaft of the joint, the upper part and the lower part of the connecting block are pivotally arranged on the pivot shaft, the handle, the sleeve and the lifting block are located at the middle position of the connecting block, the lifting block movably presses the lower part of the connecting block, the lifting block moves when the handle is rotated, and the pressing contact and the loose contact of the connecting block are realized.

[0008] Further, the lifting block movably presses the connecting block, the connecting block is positioned when being pressed, the rotating arm cannot rotate, and the connecting block can move when being loosened, so that the rotating arm can be rotated and folded.

[0009] Further, a top block is installed at the rear part of the pivot seat, the lifting block movably abuts against the top block, and the pressing effect on the connecting block can be increased.

[0010] The utility model has the advantages that the handle can be rotated to rotate the sleeve, the positioning pin moves along the limiting groove of the sleeve, the lifting block is moved up and down, the connecting block of the rotating arm is movably pressed by the lifting block, so that the rotating arm cannot rotate, when the connecting block of the rotating arm is loosened, the rotating arm can be rotated, the folding of the rotating arm is realized, and the occupied space is reduced.

[0015] Label and explanation:

[0016] Pivot joint seat 1, pivot shaft 2, handle 3, sleeve 4, lifting block 5, top block 6, limiting groove 7, positioning pin 8, connecting seat 9, connecting block 10. Specific implementation

[0017] The utility model will be further explained in connection with the drawings.

[0018] See Figure 1 --- Figure 4 The utility model discloses a controllable folding joint structure, which comprises a pivot joint seat 1, a pivot shaft 2, a handle 3, a sleeve 4, a lifting block 5, a top block 6, a limiting groove 7 and a positioning pin 8. The pivot joint seat 1 is in the shape of "]", the pivot shaft 2 is installed between the upper part and the lower part of the pivot joint seat 1, and the top block 6 is installed at the rear part of the pivot joint seat 1. The sleeve 4 is fixed on the pivot shaft 2, the outer surface of the sleeve 4 is formed with a spiral limiting groove 7, the lifting block 5 is sleeved on the sleeve 4, the positioning pin 8 is arranged through the lifting block 5, one end of the positioning pin is embedded in the limiting groove 7, and the handle 3 is fixed outside the sleeve 4.

[0019] The utility model discloses a joint, which is pivoted with a connecting block 10 on the pivot shaft 2. The connecting block 10 is in the shape of "]", the upper part and the lower part of the connecting block 10 are pivoted on the pivot shaft 2, the handle 3, the sleeve 4 and the lifting block 5 are located at the middle position of the connecting block 10, and the lifting block 5 is used for pressing the lower part of the connecting block 10.

[0020] When the joint is used, the handle 3 is rotated, the sleeve 4 is rotated, the positioning pin 8 is moved along the limiting groove 7 of the sleeve 4, the lifting block 5 is driven to realize lifting movement, the lower part of the connecting block 10 is pressed by the lifting block 5, at this time, the lifting block 5 is pressed by the top block 6, the top block 6 increases the positioning of the connecting block 10, and the connecting block 10 cannot rotate.

[0021] When the lower part of the connecting block 10 is pressed by the lifting block 5, the connecting block 10 cannot rotate around the pivot shaft 2, so that the effect that the rotating arm connected by the connecting block 10 is positioned is realized.

[0022] When the lifting block 5 moves up, the connecting block 10 is loosened, at this time, the rotary arm is rotated, the connecting block 10 rotates around the pivot 2, the rotary arm can be folded, and the occupied space is reduced.

[0023] The utility model discloses the front end fixed mounting of punch press has the connecting seat 9, the rear end of connecting seat 9 installs the joint, the rear end of connecting seat 9 rotatory connection rotary arm, the front end of rotary arm is installed with connecting block 10, and connecting block 10 rotatory connection joint. Rotary arm can rotate around joint, thereby folding to the side of connecting seat 9, greatly reduce space occupation, and the practical effect is good.

[0024] Of course, the above-mentioned embodiments are only preferred examples of the utility model, and are not limited to the scope of the utility model. Any equivalent changes or modifications made in accordance with the structure, features and principles described in the utility model patent application scope shall be included in the utility model patent application scope.
