[0020] A dual-purpose wrench for an alarm provided in an embodiment of the present application is now described.
[0021] See also Figure 1 and Figure 2 , which is a schematic diagram of the structure of the utility model at different angles, the dual-purpose wrench for the alarm comprises a wrench head 1, a first wrench hole 2 is provided on one side of the wrench head 1, and a hollow cylindrical wrench body 3 is vertically connected to the other side, and a mounting groove 6 for accommodating the alarm is provided on the side of the top of the wrench body 3 close to the first wrench hole 2; a pair of second wrench holes 5 corresponding to each other are provided at the bottom end of the wrench body 3, and the length of the connection line between the two second wrench holes 5 is equal to the diameter of the cross section of the wrench body 3.
[0022] When in use, the staff can select the corresponding wrench hole according to the size of the fire sprinkler and the pipe connected to the alarm to be repaired; when the fire sprinkler is large, the first wrench hole 2 is selected, and the staff allows the alarm to enter the internal space of the wrench body 3 through the installation slot 6, and clamps the fire sprinkler or pipe through the first wrench hole 2 on the wrench head 1, and rotates the wrench body 3 to complete the installation and disassembly of the alarm; when the fire sprinkler is small, the second wrench hole 5 is selected, and the staff allows the alarm to enter the inside of the wrench body 3, and then clamps the fire sprinkler or the two ends of the pipe with the second wrench hole 5, and completes the installation and disassembly of the alarm by rotating the wrench body 3. When the fire sprinkler and the pipe are different, there is no need to replace different wrenches, only the direction of use of the wrench needs to be reversed, which is safe and convenient to operate, saves time for replacing wrenches, saves time and effort, improves work efficiency, and has a wide range of applications.
[0023] Furthermore, a pair of fixing holes 4 corresponding to each other is formed on the wrench body 3 , and the length of the line connecting the two fixing holes 4 is equal to the diameter of the cross section of the wrench body 3 .
[0024] Furthermore, handles are detachably connected to the two fixing holes 4. When the staff needs to rotate the wrench body 3, the handles are inserted into the two fixing holes 4, and the force arm is extended by rotating the handles, so that the force on the wrench body 3 is strengthened, which is convenient for the rotation of the wrench body 3, and has a labor-saving effect during work, and is convenient for the replacement of the alarm.
[0025] Furthermore, the fixing hole 4 is located in the middle of the wrench body 3 , so that the first wrench hole 2 and the second wrench hole 5 are both subjected to the same force effect.
[0026] Specifically, the wrench head 1 is a circular structure, and the wrench head 1 and the wrench body 3 are coaxial and have the same diameter.
[0027] Specifically, the first wrench hole 2 is a radial rectangular opening.
[0028] Specifically, the center of the opening of the first wrench hole 2 on the outer periphery of the wrench head 1 and the center of one of the fixing holes 4 are distributed on the same axis, which facilitates the insertion of the handle when the first wrench hole 2 is clamped with the fire sprinkler or pipe, and the force applied to the wrench body 3 can be better transmitted to the clamping point.
[0029] Furthermore, the center of the second wrench hole 5 and the center of the fixing hole 4 are distributed on the same axis, which facilitates the insertion of the handle when the second wrench hole 5 is clamped with the fire sprinkler or pipe, and the force applied to the wrench body 3 can be better transmitted to the clamping point.
[0030] The method of using the utility model is as follows: when in use, the corresponding spanner hole is selected according to the type of the fire sprinkler or pipe to which the alarm is connected and the needs of the operation; when the fire sprinkler is large in size, the staff makes the alarm enter the internal space of the spanner body 3 through the installation slot 6, clamps the fire sprinkler or pipe through the first spanner hole 2 on the spanner head 1, and rotates the spanner body 3 to complete the installation and disassembly of the alarm; when the next fire sprinkler is small in size, the second spanner hole 5 needs to be selected, the staff rotates the wrench direction to make the alarm enter the inside of the spanner body 3, clamps the fire sprinkler or both ends of the pipe through the second spanner hole 5, and rotates the spanner body 3 to complete the installation and disassembly of the alarm.
[0031] In the utility model, a first wrench hole 2 is provided on one side of the wrench head 1, and a pair of second wrench holes 5 corresponding to each other are provided at the bottom end of the wrench body 3. During the maintenance and inspection of the alarm, when the sizes of the fire sprinkler or pipe connected to the alarm are different, the staff only needs to select the first wrench hole 2 or the second wrench hole 5 according to the size of the fire sprinkler or pipe, and turn the use direction of the wrench, without changing different wrenches. The operation is safe and convenient, saving time for changing wrenches, saving time and effort, improving work efficiency, and having a wide range of applications. A handle is detachably connected to the two fixing holes 4. The staff can extend the force arm by turning the handle to strengthen the force on the wrench body 3, which is convenient for the rotation of the wrench body 3, and has a labor-saving effect during work, and is convenient for the replacement of the alarm.
