Referring to Fig. 2 and Fig. 3, in this embodiment: the limit structure 4 includes a push ring 41, the push ring 41 is threadedly connected with the handle 1, and the arc surface of the handle 1 is evenly slidably inserted with three insertion rods 42, the insertion rods 42 is clamped with the connecting rod 3, and the other end of the insertion rod 42 is fixedly connected with a circular plate 44, and the arc surface of the insertion rod 42 is covered with a first spring 43, and the two ends of the first spring 43 are connected with the circular plate 44 and the handle respectively. 1 fixed connection. When it is necessary to fix the handle 1 and the connecting rod 3, first turn the push ring 41, and now the first spring 43 will give a elastic force to the circular plate 44, driving the insertion rod 42 to slide out from the inside of the handle 1, and then the connecting rod 3 is placed inside the handle 1, and then the push ring 41 is turned, so that the push ring 41 squeezes the circular plate 44, and the circular plate 44 drives the insertion rod 42 to slide and insert the connecting rod 3 along the inside of the handle 1, so that it can be carried out according to actual needs. The effect of replacing the fixing ring 2 and the connecting rod 3. An arc ball 45 is fixedly connected to the side of the circular plate 44 away from the insertion rod 42 , and the arc ball 45 abuts against the push ring 41 . When turning the push ring 41, since the surface of the arc ball 45 is arc-shaped, the friction between the push ring 41 and the circular plate 44 will be reduced, thereby achieving the effect of inserting the insertion rod 42 into the connecting rod 3 conveniently and quickly . The arc surface of the push ring 41 is fixedly connected with the limit ring 46, and the arc surface of the limit ring 46 is fixedly connected with the anti-slip pad 47, and the surface of the anti-slip pad 47 is provided with several anti-skid lines. When the push ring 41 is rotated, the frictional force between the hand of the operator and the limit ring 46 is increased by means of the anti-skid pad 47 , thereby achieving the effect of facilitating the rotation of the push ring 41 .

With reference to shown in Figure 4, in the present embodiment: protective structure 5 comprises two fixed plates 51, and fixed plate 51 is fixedly connected with fixed ring 2, and the upper surface of fixed plate 51 is fixedly connected with second spring 52, and the second spring 52 The other end is fixedly connected to the limiting plate 53, and the side where the two limiting plates 53 are close to each other is fixedly connected to an auxiliary plate 54, and the side of the auxiliary plate 54 near the fixed ring 2 is fixedly connected to a clamping block 57, and the clamping block 57 is connected to the fixed ring. 2-phase card connection. When the fixed ring 2 is not used, the second spring 52 will give the fixed plate 51 an elastic force, so that the clamping block 57 is snapped into the fixed ring 2, thereby achieving the effect of isolating oxygen and preventing the inner rust of the fixed ring 2 from affecting the use. A sealing strip 55 is fixedly connected to the side of the auxiliary plate 54 close to the block 57, and the sealing strip 55 is a rubber strip. The effect of better sealing the inner wall of the fixing ring 2 is achieved. The upper surface of the fixing plate 51 is fixedly connected with the limiting rod 56 , and the arc surface of the limiting rod 56 is slidably connected with the inside of the limiting plate 53 . The effect of restricting the elastic force direction of the second spring 52 is achieved.

Working principle, when it is necessary to assemble the connecting rod 3 and the fixed ring 2 on the handle 1, put the connecting rod 3 inside the handle 1 first, and then turn the anti-slip pad 47, at this time the anti-slip pad 47 plays a role in increasing the operator's hand The effect of the friction force between the fixed plate 51, and then better make the limit ring 46 drive the push ring 41 to rotate, the movement of the push ring 41 will squeeze the arc ball 45, and the movement of the arc ball 45 will drive the circular plate 44 to move, wherein The arc ball 45 has the effect of reducing the frictional force between the push ring 41 and the circular plate 44.
