[0024] The utility model provides a forest tending and pruning pruner, comprising a gripping rod 101, a collar 102, an adjustment component 103, a fixed chain 104 and a fixing mechanism, wherein the fixing mechanism comprises a housing 105, a spring 106, a connecting block 107, a limiting component 108, a plurality of locking rods 109, a shoulder strap 110, a pushing block 111, an anti-skid pattern 112, an anti-skid pad 113, anti-skid particles 114, a buckle hole 115 and a connecting hole 116, wherein the adjustment component 103 comprises a threaded rod 117 and a rotating nut 118, and the limiting component 108 comprises a positioning frame 119 and an inclined plate 120. The above-mentioned solution solves the problem in the prior art that the long-term gripping of a heavy pruner will cause fatigue and weakness in the arms of the staff. It is understandable that the above-mentioned solution can also solve the problem that the shoulder strap 110 is too long and inconvenient to be stored, by folding the shoulder strap 110 and then bundling and storing the shoulder strap 110 using the storage component.

[0025] According to this specific embodiment, the ring 102 is slidably connected to the holding rod 101 and is located on the outer wall of the holding rod 101. The fixing chain 104 is rotatably connected to the ring 102 and passes through the ring 102. The fixing mechanism is located on the side of the fixing chain 104 away from the ring 102. The adjusting component 103 is arranged on the ring 102. The fixing mechanism is used to reduce the fatigue of the hands of the staff when holding the trimmer with both hands for a long time. The adjusting component 103 is used to adjust the tightness of the ring 102 and adjust the position of the ring 102 on the holding rod 101.

[0026] The shell 105 is fixedly connected to the fixed chain 104 and is located on a side of the fixed chain 104 away from the ring 102. Communication holes 116 are provided on both sides of the shell 105. The spring 106 is fixedly connected to the shell 105 and is located inside the shell 105. The connecting block 107 is fixedly connected to the spring 106 and is located on one side of the spring 106. The locking rod 109 is fixedly connected to the connecting block 107 and is located on a side of the connecting block 107 away from the spring 106. One end of the shoulder strap 110 is fixedly connected to the shell 105 and is located on a side of the shell 105 away from the fixed chain 104. The other end of the belt 110 is provided with a plurality of buckle holes 115; the pushing block 111 is fixedly connected to the connecting block 107 and is located on both sides of the connecting block 107; the anti-slip pattern 112 is arranged on the side of the pushing block 111 away from the connecting block 107, and the anti-slip pattern 112 is used to prevent the fingers of the staff from slipping when pushing the smooth pushing block 111. In order to realize the movement of the pushing block 111, two hole structures are arranged at the place where the shell 105 is connected to the pushing block 111. The size of the pushing block 111 is larger than the size of the corresponding hole structure, so that the pushing block 111 can be moved in the hole structure of the shell 105. The connecting block 107 is moved within the range of the structure, and the locking rod 109 is used to limit the shoulder strap 110 and adjust the length of the shoulder strap 110. The staff first pushes the pushing block 111 in the direction of the fixed chain 104. Since the connecting block 107 is fixedly connected to the pushing block 111, the connecting block 107 is driven to move together. At the same time, since the locking rod 109 is fixedly connected to the connecting block 107, the locking rod 109 is also moved to a side away from the shoulder strap 110. The locking rod 109 is taken out of the limiting assembly 108, and then the buckle hole 115 at one end of the shoulder strap 110 is moved along the connecting hole 116. The shoulder strap 110 is placed in the housing 105, and after being adjusted to a suitable length, the pushing block 111 is loosened. Since the spring 106 is fixedly connected to the connecting block 107, when the pushing block 111 is pushed in the direction of the fixed chain 104, the spring 106 is also compressed. At this time, due to the loosening of the pushing block 111, the elasticity of the spring 106 acts on the locking rod 109, and the locking rod 109 is inserted into the buckle hole 115 on the shoulder strap 110. At the same time, it is also inserted into the limiting assembly 108. The staff puts the shoulder strap 110 on the shoulder to reduce the fatigue of the hands caused by holding the trimmer for a long time.

[0027] At the same time, the positioning frame 119 is fixedly connected to the outer shell 105 and is located on the outer wall of the locking rod 109. The positioning frame 119 is provided with a through hole corresponding to the locking rod 109. The inclined plate 120 is respectively fixedly connected to the positioning frame 119 and the outer shell 105 and is located on one side of the positioning frame 119. The positioning frame 119 is used to limit the locking rod 109, and the inclined plate 120 is used to improve the fixing effect of the positioning frame 119 and the outer shell 105.

[0028] Among them, the rotating nut 118 is fixedly connected to the ring 102 and is sleeved on the ring 102. The threaded rod 117 is threadedly connected to the rotating nut 118 and passes through the rotating nut 118. The rotating nut 118 and the threaded rod 117 are used to adjust the tightness of the ring 102 and adjust the position of the ring 102 on the holding rod 101. By sliding the position of the ring 102 on the holding rod 101 and adjusting it to a suitable position, the tightness of the ring 102 can be adjusted by rotating the threaded rod 117.

[0029] Secondly, the anti-skid pad 113 is slidably connected to the shoulder strap 110 and is located on the outer surface of the shoulder strap 110. The anti-skid particles 114 are fixedly connected to the anti-skid pad 113 and are located on the side of the anti-skid pad 113 away from the shoulder strap 110. The anti-skid pad 113 is used to increase the contact area with the shoulder. The anti-skid particles 114 are made of anti-skid cloth, so that the anti-skid pad 113 is not easy to fall off or slide when in contact with clothes.

[0030] When using the forest tending and pruning pruner of the present embodiment, the position of the ring 102 on the gripping rod 101 is first adjusted to a suitable position by sliding the ring 102, and then the tightness of the ring 102 is adjusted by rotating the threaded rod 117. The staff then pushes the pushing block 111 in the direction of the fixed chain 104. Since the connecting block 107 is fixedly connected to the pushing block 111, the connecting block 107 is driven to move together. At the same time, since the locking rod 109 is fixedly connected to the connecting block 107, the locking rod 109 is also driven to move in a direction away from the shoulder strap 110. The locking rod 109 is taken out of the positioning frame 119, and then the shoulder strap 110 is fixedly secured by the buckle hole 115 at one end of the shoulder strap 110 along the connecting hole 116. 0 is placed in the housing 105, and after adjusting to a suitable length, the pushing block 111 is loosened. Since the spring 106 is fixedly connected to the connecting block 107, when the pushing block 111 is pushed toward the fixed chain 104, the spring 106 is also compressed. At this time, the pushing block 111 is loosened. Since the elasticity of the spring 106 acts on the locking rod 109, the locking rod 109 is moved toward the direction of the positioning frame 119 and inserted into the buckle hole 115 on the shoulder strap 110. At the same time, it is also inserted into the through hole of the positioning frame 119. The staff then slides the anti-slip pad 113 on the shoulder strap 110 to the middle position and places it on the staff's shoulder, thereby reducing the fatigue of the hands caused by holding the trimmer for a long time.
