[0002] A force rod is a hand tool primarily used to increase torque and make manual operations easier. It's commonly used to tighten screws or nuts, and is particularly useful when working with difficult nuts or bolts. By amplifying manual effort, the force rod increases torque, helping to tighten parts like cranks. Alternatively, the term "force rod" can refer to a rod used with a torque wrench to increase leverage, making it easier to apply high torques. When using a force rod, pay attention to its length and diameter to ensure it matches the tool and avoid errors and inaccurate measurements.

[0003] In order to increase the operating range of the boosting rod currently on the market, a telescopic device is usually added to the boosting rod when in use, so that the boosting rod can be used to tighten the screw or nut. However, the switches of the existing telescopic devices are mostly exposed on the outer surface of the boosting rod. When workers are working, it is very easy to accidentally touch the switch, causing the telescopic device to open, affecting work efficiency. Therefore, it is necessary to propose a boosting rod auxiliary switch to solve the above problem. Utility Model Content

[0006] The top end of the extension column is rotatably connected to a fixed plate, and two telescopic rods are fixedly connected to the lower surface of the inner wall of the shell. The two telescopic rods are symmetrically distributed on the lower surface of the inner wall of the shell, and the telescopic ends of the telescopic rods are fixedly connected to the lower surface of the fixed plate. The telescopic rods extend and retract with the movement of the fixed plate, and are used for limiting the fixed plate.

[0007] Preferably, a connecting column is fixedly connected to the middle of the upper surface of the fixing plate, a connecting ring is fixedly connected to the top of the connecting column, and a nut groove is provided on one side of the connecting ring extending through to the other side.

[0010] Compared with the prior art, the present invention provides a force-adding rod auxiliary switch, which has the following beneficial effects:

[0011] The utility model protects the switch by means of a protective cover which can be detachably connected to the shell. Since the protective cover is made of rubber material and has a certain elasticity, when the switch needs to be protected, it is only necessary to rotate the protective cover to rotate the switch slot to a side away from the switch, thereby completing the protection of the switch and preventing workers from accidentally touching the switch when the force rod is in use, thereby improving the operating efficiency of the force rod. The device has a simple structure and is easy to use, meeting existing usage needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Reference Figure 1-3 As shown, a force-adding rod auxiliary switch includes: a housing 1, a drive motor 2, a connecting plate 3, a rotating frame 4, a threaded groove 5 and an extension column 6. The drive motor 2 is fixedly mounted on the middle part of the lower surface of the inner wall of the housing 1, the output end of the drive motor 2 is fixedly mounted on the connecting plate 3, the top of the connecting plate 3 is fixedly connected to the rotating frame 4, the inner wall of the rotating frame 4 is provided with a threaded groove 5, the interior of the rotating frame 4 is provided with an extension column 6, the surface of the extension column 6 is provided with a thread 7, and the thread 7 is threadedly connected to the thread groove 5.

[0019] Furthermore, the top end of the extension column 6 is rotatably connected to a fixing plate 8 , and the lower surface of the inner wall of the housing 1 is fixedly connected to two telescopic rods 9 , which are symmetrically distributed on the lower surface of the inner wall of the housing 1 .

[0020] The telescopic end of the telescopic rod 9 is fixedly connected to the lower surface of the fixed plate 8. The telescopic rod 9 is extended and retracted as the fixed plate 8 moves, and is used for limiting the fixed plate 8.

[0021] A connecting column 10 is fixedly connected to the middle of the upper surface of the fixing plate 8 , and a connecting ring 11 is fixedly connected to the top of the connecting column 10 . A nut groove 12 is formed from one side of the connecting ring 11 to the other side.

[0022] A switch 13 is provided at the bottom of one side surface of the housing 1 . The switch 13 is electrically connected to the drive motor 2 . There are two switches 13 , which can respectively control the drive motor 2 to rotate counterclockwise or clockwise.

[0023] In the present invention, a protective sleeve 14 is provided at the bottom of the housing 1. The protective sleeve 14 is detachably connected to the bottom of the housing 1. A switch slot 15 is formed on one side of the protective sleeve 14. The switch slot 15 is adapted to fit the switch 13. By rotating the protective sleeve 14 to change the position of the switch slot 15, the protective operation of the switch 13 is achieved.

[0024] When the present invention is used, first press the switch 13 to turn on the drive motor 2 to drive the connecting plate 3 to rotate, the connecting plate 3 drives the rotating frame 4 to rotate, the rotating frame 4 drives the extension column 6 threadedly connected thereto to move, so that it extends or retracts, and the extension column 6 drives the fixed plate 8 to move.
