[0033] Please refer to Figures 1 to 3 In some embodiments, the locking piece 22 is a bolt installed in the limiting hole 13 through a threaded pair.

[0034] The locking piece 22 of the application is a bolt installed in the limiting hole 13 through a threaded pair. The bolt is conveniently installed in the limiting hole 13 through the threaded pair. When the fixing sleeve 1 is to be fixedly installed on the electric valve, the debugging personnel rotates the bolt by using a wrench, moves the bolt to the center of the first accommodating cavity 11, clamps the electric valve by the bolts around, and keeps the electric valve stationary with the locking piece 22 and the fixing sleeve 1. Then, the debugging personnel installs the torque wrench on the matching part 3, rotates the torque wrench, analyzes whether the electric valve is damaged according to the displayed value on the torque wrench, and thus the operation is more convenient and the manufacturing cost is lower, and the debugging personnel is facilitated to operate.

[0035] Please refer to Figures 1 to 5 In some embodiments, the clamping piece 21 comprises a guide piece 211 and an extrusion block 212. The guide piece 211 is slidingly connected to the fixing sleeve 1, and the extrusion block 212 is fixedly installed at the end of the guide piece 211. The locking piece 22 is rotationally connected to the extrusion block 212, and drives and limits the extrusion block 212 to approach or move away from the center of the first accommodating cavity 11.

[0036] In the application, the extrusion block 212 is fixedly installed at the end of the guide piece 211, the locking piece 22 is rotationally connected to the extrusion block 212, and the extrusion block 212 is driven and limited to approach or move away from the center of the first accommodating cavity 11. The rotation of the extrusion block 212 is limited by the guide piece 211, so that the extrusion block 212 can only approach or move away from the center of the first accommodating cavity 11 in the direction perpendicular to the axis of the fixing sleeve 1. The connection strength between the extrusion block 212 and the fixing sleeve 1 is further improved, the extrusion blocks 212 around can more stably clamp the electric valve, the contact area between the extrusion block 212 and the electric valve can be increased, the friction between them is further improved, the damage to the electric valve during clamping can be reduced, the clamping between the extrusion block 212 and the electric valve is more stable, the value on the torque wrench during analysis by the torque wrench is more accurate, and the analysis efficiency and accuracy are improved. When the electric valve is clamped, the locking piece 22 can be a bolt. The debugging personnel rotates the locking piece 22, uses the threaded pair between the bolt-shaped locking piece 22 and the limiting hole 13, and rotates the locking piece 22 into the center of the first accommodating cavity 11. The extrusion block 212 at the end is driven to approach the center of the first accommodating cavity 11 during movement, and clamps the electric valve. Similarly, when the electric valve is to be disassembled from the first accommodating cavity 11, the debugging personnel reversely rotates the locking piece 22, drives the extrusion block 212 to move away from the center of the first accommodating cavity 11 by the locking piece 22, and separates the extrusion blocks 212 around from the electric valve. Thus, the whole analysis process is simple in operation, the damage to the electric valve is reduced, and the analysis efficiency and accuracy are improved.

[0037] Please refer to Figures 1 to 6In some embodiments, the extrusion block 212 is arranged in a circular arc shape, and an elastic pad 213 is arranged between the extrusion block 212 and the electric valve.

The circular arc-shaped extrusion block 212 can more stably clamp the cylindrical electric valve, improve the analysis efficiency and accuracy of the electric valve, and thus improve the range of use.

[0039] The extrusion block 212 can also be flat or polygonal. The extrusion block 212 can be matched with the shape of the electric valve according to the shape of the electric valve, so as to clamp different models of electric valves and further improve the range of application.

[0040] The elastic pad 213 arranged between the extrusion block 212 and the electric valve can further increase the friction between the extrusion block 212 and the electric valve during clamping, so that the connection between the fixing sleeve 1 and the electric valve is more firm and stable, and thus the analysis result is more accurate. The elastic pad 213 can also protect the electric valve from moving and reduce the wear of the electric valve by the extrusion block 212 during clamping, thereby reducing the maintenance cost.

[0041] Please refer to Figures 1 to 6 In some embodiments, a plurality of anti-skid grooves 214 are formed on the elastic pad 213.

[0042] The plurality of anti-skid grooves 214 formed on the elastic pad 213 can further increase the friction between the extrusion block 212 and the electric valve, so that the connection between the fixing sleeve 1 and the electric valve is more firm and stable.

[0043] Please refer to Figures 1 to 5 In some embodiments, a slot hole 12 is formed on the fixing sleeve 1 and is in communication with the first accommodating cavity 11 and parallel to the axis of the fixing sleeve 1.

[0044] The slot hole 12 formed on the fixing sleeve 1 is in communication with the first accommodating cavity 11 and parallel to the axis of the fixing sleeve 1. When a flat key is arranged on the electric valve, the debugging personnel slides the flat key of the electric valve into the slot hole 12 when the fixing sleeve 1 is sleeved on the electric valve. The flat key and the slot hole 12 are matched to further increase the stability between the fixing sleeve 1 and the electric valve. The use range of the electric valve torque verification conversion tool is further expanded, more electric valve models can be used, the labor intensity is reduced, and the operation is more convenient.

[0045] Please refer to Figures 1 to 5In some embodiments, one of the bolts is installed on the part of the fixing sleeve 1 corresponding to the slot hole 12.

The bolt cooperates with the slot hole 12 to further stably and firmly fix the electric valve in the first accommodating cavity 11, thereby improving stability and analysis accuracy.

[0047] Please refer to Figure 1 and Figure 7 In some embodiments, the locking member 22 includes a locking rod 221, the clamping member 21 is provided with a plurality of through holes 222, and the fixing sleeve 1 is provided with a locking hole 223 cooperating with one of the through holes 222.

The locking hole 223 is provided on the fixing sleeve 1 and communicates with the limiting hole 13, and the plurality of through holes 222 are provided according to different models of electric valves. The closer the through hole 222 to the first accommodating cavity 11, the larger the model of the electric valve, and the farther the through hole 222 to the first accommodating cavity 11, the smaller the model of the electric valve. When the through hole 222 communicates with the locking hole 223, the clamping member 21 around the through hole 222 can stably clamp the electric valve in the first accommodating cavity 11. Several through holes 222 are provided on the clamping member 21 to correspond to the fixing and clamping of several models of electric valves. During clamping, the installer moves the corresponding model of the through hole 222 to coincide with the locking hole 223, and then inserts the locking rod 221 into the locking hole 223 and the through hole 222, so that the clamping member 21 remains relatively stationary on the fixing sleeve 1, stably clamping the electric valve in the first accommodating cavity 11. Then, the torque wrench and the matching part 3 are fixed and cooperated to analyze the electric valve. The operation is more convenient and labor-saving, the structure is simpler, and the clamping efficiency is improved.
