所述的扭力圈7在安装孔6内可相对转动，所述的扭力圈7与顶块10为一体成型结构。The torsion ring 7 is relatively rotatable in the installation hole 6 , and the torsion ring 7 and the top block 10 are integrally formed.
所述的安装孔6和容置腔12连通，所述的连通的位置右侧为档点11，所述的容置腔12为“﹄”结构，所述的“﹄”结构上部具有一定长度S1。The mounting hole 6 communicates with the accommodating cavity 12 , the right side of the communicating position is the stop point 11 , the accommodating cavity 12 has a "﹄" structure, and the upper part of the "﹄" structure has a certain length S1.
所述的档点11到容置腔12右侧的内壁面的距离S大于或等于弹簧12最大压缩的距离，从而防止弹簧12被过度压缩而失效。弹簧到达最大压缩后，由于档点11的作用，顶块10不再位移，从而防止弹簧12被过度压缩而失效。The distance S from the stop point 11 to the inner wall surface on the right side of the accommodating cavity 12 is greater than or equal to the maximum compression distance of the spring 12, thereby preventing the spring 12 from being over-compressed and failing. After the spring reaches the maximum compression, due to the action of the stop point 11, the top block 10 is no longer displaced, thereby preventing the spring 12 from being over-compressed and failing.
所述的顶块10后端部与扭力圈7相交的位置的扭力圈上设有指示箭头5。The torsion ring at the position where the rear end of the top block 10 intersects with the torsion ring 7 is provided with an indicating arrow 5 .

所述的扭力圈7内壁为配合螺栓头的多边形啮合口。该扭力圈7内壁的多边形结构与普通的扳手内壁结构一样。The inner wall of the torsion ring 7 is a polygonal meshing opening that matches the bolt head. The polygonal structure of the inner wall of the torsion ring 7 is the same as that of a common wrench inner wall.
实施例1：如图6-8，本发明专利例如为螺栓规格为M10*1.5P，螺栓等级为8.8级的，最小破坏扭矩设为66N.m，当该梅花扳手头套于螺栓上进行施力的时候，由于力的作用是相互，当对扳手从右往左施力时候，螺栓会给扭力圈从左往右的力，从而带动扭力圈从左往右旋转，扭力圈的旋转带动顶块旋转，从而顶块将弹簧压缩，当对扳手的力逐渐增大时，顶块对将弹簧压缩越大，其扭力圈的旋转位移越大，指示箭头将不断从左往右移动，由于指示箭头下方设有指示牌，箭头位置移动从可施力范围指示区域移动到不可施力范围指示区域时候，就要停止用力，如果继续用力，箭头位置将移动到极限范围指示区域，此时，可能会破坏螺栓扭矩，由于本发明设置了档点，所以本发明尽管不管施加外力，当顶块顶于档点后，其顶块就不会发生位移，由于设有档点，所以本发明防止了弹簧被过度压缩而失效。图6指示箭头处于可施力范围指示区域，图7指示箭头处于不可施力范围指示区域，图8指示箭头处于极限范围指示区域。Example 1: As shown in Figure 6-8, the patent of the present invention is for example, the bolt specification is M10*1.5P, the bolt grade is 8.8, and the minimum breaking torque is set to 66N.m, when the Torx wrench head is put on the bolt to apply force When the force is applied to each other, when the wrench is applied from right to left, the bolt will force the torsion ring from left to right, thereby driving the torsion ring to rotate from left to right, and the rotation of the torsion ring drives the top block Rotate, so that the top block compresses the spring. When the force on the wrench gradually increases, the more the top block compresses the spring, the greater the rotational displacement of its torsion ring, and the indicating arrow will continue to move from left to right. There is a sign below. When the arrow position moves from the area where the force can be applied to the area where the force cannot be applied, stop applying force. If you continue to apply force, the arrow position will move to the limit area indicating area. Destruction of bolt torque, because the present invention sets a stop point, so despite the application of external force, when the top block is pressed against the stop point, the top block will not be displaced. Because of the stop point, the present invention prevents the spring is over-compressed and fails. Fig. 6 indicates that the arrow is in the force-applicable range indication area, Fig. 7 indicates that the arrow is in the force-impossible range indication area, and Fig. 8 indicates that the arrow is in the limit range indication area.
实施例2：如图9-11，螺栓规格为M10*1.5P，螺栓等级为12.9级的，最小破坏扭矩设为90N.m；当该梅花扳手头套于螺栓上进行施力的时候，由于力的作用是相互，当对扳手从右往左施力时候，螺栓会给扭力圈从左往右的力，从而带动扭力圈从左往右旋转，扭力圈的旋转带动顶块旋转，从而顶块将弹簧压缩，当对扳手的力逐渐增大时，顶块对将弹簧压缩越大，其扭力圈的旋转位移越大，指示箭头将不断从左往右移动，由于指示箭头下方设有指示牌，箭头位置移动从可施力范围指示区域移动到不可施力范围指示区域时候，就要停止用力，如果继续用力，箭头位置将移动到极限范围指示区域，此时，可能会破坏螺栓扭矩，由于本发明设置了档点，所以本发明尽管不管施加外力，当顶块顶于档点后，其顶块就不会发生位移，由于设有档点，所以本发明防止了弹簧被过度压缩而失效。图9指示箭头处于可施力范围指示区域，图10指示箭头处于不可施力范围指示区域，图11指示箭头处于极限范围指示区域。Example 2: As shown in Figure 9-11, the bolt specification is M10*1.5P, the bolt grade is 12.9, and the minimum breaking torque is set to 90N.m; When the wrench is applied from right to left, the bolt will force the torsion ring from left to right, thus driving the torsion ring to rotate from left to right, and the rotation of the torsion ring drives the top block to rotate, so that the top block Compress the spring, when the force on the wrench gradually increases, the more the top block compresses the spring, the greater the rotational displacement of its torsion ring, the indicating arrow will move from left to right continuously, because there is an indicating sign below the indicating arrow , when the arrow position moves from the area indicated by the range that can be applied to the area indicated by the range that cannot be applied, stop applying force. If you continue to apply force, the position of the arrow will move to the area indicated by the limit range. At this time, the bolt torque may be damaged. The present invention is provided with a stop point, so the top block will not be displaced when the top block is pressed against the stop point, regardless of the external force being applied. Because of the stop point, the present invention prevents the spring from being over-compressed and failing. . Fig. 9 indicates that the arrow is in the indication area of the forceable range, Fig. 10 indicates that the arrow is in the indication area of the unapplyable range, and Fig. 11 indicates that the arrow is in the limit range indication area.
