[0026] The working principle and use process of the utility model are as follows:

[0027] After the garden pruning knife body is used, the limiting ring 4 is pulled upwards, the two connecting rods 7 are driven to rotate on the outside of the two supporting columns 6 through the limiting ring 4, because the connecting rod 7 is connected with the outside of the supporting column 6 through the torsional spring 8, so that the torsional spring 8 is stretched when the connecting rod 7 rotates, and the two handles 2 are pulled, the distance between the fixed block 3 and the positioning block 5 is adjusted, after the distance is adjusted, the limiting ring 4 is released, under the rebounding action of the torsional spring 8, the limiting ring 4 is driven to move towards the positioning block 5, and the limiting ring 4 is sleeved on one end of the positioning block 5, and one side of the limiting ring 4 enters the inside of the clamping groove 9, the two handles 2 are limited through the cooperation of the limiting ring 4 and the positioning block 5, and the movement of the two handles 2 is prevented;

[0028] When the limiting ring 4 enters the inside of the clamping groove 9 on one side, the outer side of the limiting ring 4 will extrude the side of the extrusion plate 10 away from the spring 11, and since the side of the extrusion plate 10 away from the spring 11 is arranged in an arc shape, when the limiting ring 4 extrudes it, the extrusion force caused by the limiting ring 4 to it will be converted into a pushing force through the arc surface arranged on one side of the extrusion plate 10, so that the extrusion plate 10 moves to the spring 11 direction and extrudes the spring 11, and under the elastic action of the spring 11, the extrusion plate 10 will be pushed to move to the limiting ring 4 direction, so that the extrusion plate 10 extrudes the outer side of the limiting ring 4, improves the stability of the limiting ring 4 in the inside of the clamping groove 9, and the telescopic column 12 will move to the inside of the recess 13 at the same time when the extrusion plate 10 moves to the spring 11 direction, and through the limiting of the telescopic column 12, the spring 11 can be prevented from being bent, and the normal operation of the extrusion plate 10 is ensured.

[0029] The fixed disc 14 arranged on one end of the supporting column 6 limits the connecting rod 7, so that the connecting plate will not be separated from the supporting column 6.

[0030] At the same time when the limiting ring 4 enters the inside of the clamping groove 9, the inside of the clamping groove 9 will extrude the positioning rod 15 arranged on the inside of the limiting ring 4, and since the top and bottom of the side of the positioning rod 15 away from the spring 17 are arranged in an inclined manner, the positioning rod 15 will move to the inside of the storage groove 16 and extrude the spring 17 when it is extruded, and when the bottom of the limiting ring 4 contacts the bottom end inside the clamping groove 9, the positioning rod 15 will be driven to move to the inside of the positioning groove 18 under the elastic action of the spring 17, and through the cooperation between the positioning rod 15 and the positioning groove 18, the limiting ring 4 is limited, and the stability of the limiting ring 4 is improved.

[0031] The protective shell 19 arranged on the outer side of the blade 1 can cover the blade 1, so that the blade 1 will not damage other objects, and the insertion slot matched with the blade 1 is arranged on the inside of the protective shell 19, so that the blade 1 can be better limited, and the protective shell 19 can be disassembled.
