[0015] By adopting the above technical solutions, the foam design increases the comfort of holding the device.

[0016] As a further embodiment of this utility model: the arm force tube includes a first arm force spring in the middle, a second arm force spring is sleeved on the outside of the first arm force spring, the adjusting tube is sleeved with a limiting ring, and the first arm force spring and the second arm force spring are located inside the limiting ring.

[0017] By adopting the above technical solution, the limiting ring is located on both sides of the first arm spring and the second arm spring, and plays a limiting role on the first arm spring and the second arm spring.

[0018] As a further improvement of this utility model: the middle part of the handle is provided with an inwardly recessed groove, and a semi-circular block is integrally connected to one end of the handle.

[0019] By adopting the above technical solution, the recessed groove facilitates the picking up of the handle, and the semi-circular block facilitates the placement of the handle.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] When the length needs to be adjusted, the adjusting tube is moved so that the locking block is in different adjusting holes, thereby adjusting the length of the connecting tube and the adjusting tube. The setting of the reset piece ensures that the locking block always has an outward force, and the setting of the handle makes it easy for technicians to hold. Attached Figure Description
